Description

ink refill container

technical field

The utility model relates to an ink supplement container.

Background technique

Conventionally, an inkjet printer is known as an example of an ink jetting device that can print on a recording medium using ink by jetting ink from a recording head toward a recording medium such as recording paper. In such an inkjet printer, a user can replenish ink to an ink tank storing ink supplied to a recording head. As a bottle (ink refill container) suitable for injecting ink into an ink tank, Patent Document 1 discloses that bottles having different ink storage capacities are provided with caps having a common shape to diversify the bottles.

(1) For a container that stores viscous or liquid in the container, forms a seal such as aluminum foil at the mouth of the container, and uses a cap that is screwed into the mouth of the container from above to close the lid, conventionally, Examples include tube containers, squeeze bottles, and the like. In particular, when the content of the container deteriorates due to contact with oxygen, in order to prevent the intrusion of oxygen into the container, a laminated sealing material mainly using aluminum foil is used. In this type of container, the container is unsealed by opening the lid, but at this time, it is necessary to form a grip portion on the sealing member that can be grasped by fingers, and to grasp the grip portion to peel off the sealing member.

(2) As a well-known cap, Patent Document 2 discloses a cap having an inner plug as a cap main body and an outer cap as an upper cap, and a main body-side cylindrical portion and an engraved portion are provided on the inner plug. The separation part provided at the front end of the main body side cylindrical part is connected with the mark. In this cap, the separation part separated from the main body side cylindrical part by tightening the outer cap is held by the annular protrusion extending downward from the upper end inner wall of the outer cap. In addition, as the threaded structure of the cap, Patent Document 3 discloses a cap in which an external thread that is threadedly engaged with the cap and a neck ring provided below the external thread are provided on the outer peripheral surface of the mouth of the container. Multiple parts of the cover form multiple protrusions that are pressed against the inner surface of the cover to prevent loosening.

(3) Conventionally, a liquid pouring container is known in which a detachable inner plug is attached to the mouth of the container, and the container body, inner plug, and cap can be disposed of separately after use. There are many kinds of liquid injection containers from which the inner plug can be separated, and a liquid injection container equipped with a shoulder-score type (Japanese: ショルダースコアタイプ) inner plug as shown in FIG. 20 is typically known. .

In FIG. 20 , Aa is the container main body, Ba is the inner plug, and Ca is the cap, and an engaging protrusion 361 is provided on the outer periphery of the container mouth 360 of the container main body Aa. The fitting cylinder portion opposite to the container mouth 360 of the inner plug Ba is composed of an inner cylinder 362, an outer cylinder 363 and a shoulder wall 364. There is a certain amount of interference between the inner cylinder 362 and the inner peripheral surface of the container mouth 360. For fitting, the inner surface of the outer cylinder 363 fits with the outer peripheral surface of the engaging protrusion 361 of the container mouth 360, and the lower end of the outer cylinder 363 is provided with an engaging protrusion that engages with the lower surface of the engaging protrusion 361. Article 365.

In order to separate the inner plug Ba, a notch 367 is formed in one part of the outer cylinder 363 to leave a thin cuttable connection part 366, and the engagement protrusion 365 corresponding to the notch 367 is removed. A cut hole 368 continuous with the notch 367 is cut along the inner circumference of the outer cylinder 363 on the shoulder wall 364 , and a V-shaped cutting groove is engraved on the lower surface of the shoulder wall 364 extending from the cut hole 136 .

(4) In recent years, regarding synthetic resin containers for storing various liquids and other contents, thin-walled containers that reduce the amount of resin used have been developed in order to reduce the burden on the environment. In addition, refill containers such as stand-up bags are often used as containers for storing various contents. The refill container replenishes the stored contents to the refill container equipped with a pump device on the cover body, or the refill container equipped with a pouring part such as a spout spout, so that high-value refill containers are not discarded every time. And can be used for a long time.

In addition, in Patent Document 4, as a refill container for replenishing contents to a container to be refilled that does not have a spout such as a spout, a refill container is disclosed, which has an attachment cylinder attached to the mouth of the refill container. A spout is formed; an operating member is slidably supported by the installation cylinder; and a pressing body is arranged in the installation cylinder, and the operation member is slid through the mouth of the container to be replenished, so that the pressing body presses the opening of the spout. The sealing body of the sealing part opens the spout.

(5) Conventionally, thin-walled bag containers formed of films have been widely used as refill containers. As such a bag container, Patent Document 5 discloses a stand-up bag in which frills (Japanese: ガセット) portions are provided on the upper and lower sides of the bag container, and a spout portion is provided on the upper portion.

(6) Conventionally, there are liquid products in which a liquid is contained in a container. In these liquid products, a liquid pouring cap for pouring out the liquid inside is attached to the orifice of the container. When using such a liquid product, usually, the container is pressed (squeezed) with the orifice of the container facing downward. As a result, the liquid in the container is poured out from the spout of the cap. However, in the conventional liquid pouring cap, the liquid discharge property is poor, and the liquid inside leaks out only by turning the orifice of the container downward, so it is not always easy to use.

Therefore, Patent Document 6 discloses a liquid injection cap called a self-sealing cap (hereinafter referred to as SS cap), which is configured such that a valve made of soft resin with a slit is provided on the cap body. spool, the slit does not open if the pressure in the container is not applied to the spool to a certain extent. In a liquid pouring container equipped with such an SS cap, even if the container is turned over or turned upside down, the liquid inside does not easily leak from the cap, and thus is more convenient to use than conventional liquid pouring containers. In addition, the operation of opening and closing the cover as in the past can be omitted, so it is very convenient. As other patent documents, there are patent documents 7, 8, 9, 10, and 11.

(7) In a plastic bottle containing a viscous content, it is desired to have a primary sealing performance for ensuring the integrity of the content, and a discharge performance for enabling good drainage when the content is poured out. At present, a pull-tab type inner plug for viscous contents etc. generally uses a cut score as a primary seal for ensuring the authenticity of the contents (see Patent Documents 12 and 13).

(8) As a pouring cap for a container mounted on the mouth and neck portion of the container, Patent Document 14 discloses a configuration comprising a mounting cylinder, a pouring cylinder for pouring out the contents of the container, and a Engagement means such as threads or snapping parts are fixed and held on the mouth and neck of the container; the base of the cover is fixed on the mouth and neck of the container by covering the surface of the mounting cylinder; The spout path of the spout cylinder is sealed by matching the bulge provided on the upper part of the cap base.

(9) Conventionally, there is known a spout plug which is composed of a nozzle body attached to the mouth of a container and a lid covering the nozzle body, and is configured by connecting the nozzle body and the lid via a hinge. In the existing spout plug, after opening the lid and tilting the opposite side of the hinge (the side opposite to the hinge) downward to pour out the contents, there is a residue of the contents dripped from the spout. On the upper surface periphery of the nozzle body, when the lid is closed, the liquid remaining on the upper surface periphery of the nozzle body scatters because the lower surface of the annular wall of the lid contacts the upper surface of the nozzle body. To address this problem, Patent Document 15 discloses a pouring tool that avoids direct collision between the lower surface of the cap and the upper surface of the pouring tool body by forming a protrusion on the top surface of the pouring tool, thereby preventing liquid from scattering.

(10) Conventionally, when pouring a liquid content from a container, a cap provided with a pouring tube is attached to the opening of the container and used. As one form of such a pouring cap, an integral cap in which a cover is integrally molded via a hinge can be used (see Patent Document 16).

For the container, use a flexible plastic container. When pouring out the contents, squeeze the container while tilting to squeeze out the contents. When the pouring is complete, stop squeezing and return the container to its original position. . Here, the content in the injection cylinder is pulled back into the container due to its own weight or the suction force (suckback) when the container recovers from the squeezed state, but especially when the content is high in viscosity, the injection cylinder The content inside tends to remain around the sprue or in the spout, causing liquid to drip and contaminate the spout.

As a technique for solving such a problem, in the content disclosed in Patent Document 17, a curved surface composed of a diameter-reducing portion that gradually decreases in diameter from the front end of the injection cylinder portion and a diameter-expanding portion that increases in diameter toward the base end is formed. , in particular, the angle formed by the straight line connecting the outer peripheral front edge of the connecting portion connected to the mouth of the container and the outer peripheral front edge of the injection cylinder portion and the straight line perpendicular to the axis of the front end of the injection cylinder portion It is 45°～90°.

Utility model content

Technical problems to be solved by the utility model

(1) Since the seal is firmly sealed on the mouth of the container, and the seal itself is small and the area of the handle is also small, the operation of peeling off the seal is very troublesome. When the peeling operation cannot be performed smoothly, the contents May spill or scatter and stain hands and clothes. In particular, when the contents of the container are attached to clothes and it is difficult to remove them, the peeling operation of the seal is difficult even if it is performed carefully, so that the contents may be spilled or Scatter and stain hands and clothes, causing discomfort to users.

Therefore, there is a desire for a container that does not require the operation of peeling off the seal at the mouth of the container after the cap is detached from the container body.

(2) In the lid described in Patent Document 2, it can be easily opened only by screwing the outer lid, and the separation part separated by opening can be held on the inner wall of the upper end of the outer lid as a seal after unsealing It works, so the operability is very good, that is, it is easy to use. In this cap, a primary seal is provided at the lower end of the outer cover to prevent unintentional opening, but it is conceivable to omit the primary seal when miniaturization or cost is prioritized. However, when the cap with the primary seal is simply omitted, the outer cap tends to loosen when the container with the cap before opening is transported. Here, as described in Patent Document 3, for example, it is conceivable to form a plurality of protrusions on the side of the container body that are pressed against the outer cover to prevent loosening, but since a large force is required not only before unsealing, but also after unsealing Since opening and closing are performed, there is a possibility that operability may be lowered.

Therefore, there is a need for a container that can be easily opened, can prevent accidental opening, and can be easily attached and detached after opening.

(3) In the liquid pouring container shown in FIG. 20 , when the inner plug Ba is made separable, in the part of the cut hole 368 and the cut groove, the lower surface of the shoulder wall 364 and the mouth top surface The airtightness between 370 is reduced. In addition, in the cut-out portion of the engaging protrusion 365, not only the airtightness between the inner peripheral surface of the outer cylinder 363 and the outer peripheral surface of the engaging protrusion 361 of the container mouth 360 is reduced, but also the shoulder The airtightness of the lower surface of the wall 364 is also reduced. If the inner peripheral edge of the top surface 370 of the mouth is damaged, scratches are attached to the inner cylinder 362 when the inner plug Ba is inserted, and a thin strip, that is, a fine continuous hole is formed between the inner cylinder 362 and the inner circumference of the container mouth 360. , impair the airtightness of the inside of the container, and in particular, if there is a scratch at the portion corresponding to the cut hole 368, there is a problem of liquid leakage.

However, in the conventional container main body Aa, the outer peripheral edge of the mouth top surface 370 of the container mouth 360 and the connecting portion 366 of the engaging protrusion 361 are rounded with a very small arc at the corner 370a ( FIG. 21 ). , or almost no rounding state. Therefore, when the container main body Aa is transported in the factory or when it is packaged and transported, the container main bodies Aa collide with each other, and the outer peripheral edge of the mouth top surface 370 of the container main body Aa collides with the inner surface of the mouth top surface 370 of another container main body Aa. Collision between the peripheral edge and the outer peripheral edge produces recesses 371, 372 as shown in FIG. 21 and scratches 373, thereby damaging the mouth top surface 370 of the container main body Aa.

In particular, damage to the inner peripheral surface of the mouth top surface 370 (recess 371 ) scratches the inner cylinder 362 of the inner plug Ba during insertion as described above, causing liquid leakage. In order to remove the damaged container main body Aa on the mouth top surface 370 of the container mouth 360, inspection may be performed between filling liquids, but there is a problem that costs for the inspection are incurred.

Therefore, it is desired that such a container can prevent the container bodies from colliding with each other during the transportation of the molded container main body or during the package transportation in the liquid pouring container equipped with a separable inner plug or a hinged lid. In the event of damage to the top surface of the mouth of the container main body, scratches will not be formed on the inner plug or the fitting part of the inner tube of the hinge lid when plugging, and the liquid will not leak.

(4) The existing stand-up pouch is formed of a flexible packaging material with good flexibility and elasticity, and the container is easily deformed and becomes unstable when the replenishment operation is performed. On the other hand, in the replenishing container of Patent Document 4, when the spout is opened, the liquid flowing from the replenishing container toward the container to be replenished flows through almost the entire area in the assembly cylinder, so the liquid flows into the container to be replenished. Insufficient discharge of the internal air may take time to replenish, or the liquid adhering to the vicinity of the mouth of the container to be replenished may be pushed back by the air discharged from the container to be replenished and leak from the gap between the containers.

Therefore, there is a need for a container that efficiently discharges the internal air accompanying the liquid flowing into the container to be replenished, and that can smoothly replenish the contents while preventing the liquid from overflowing.

(5) The existing bag container is relatively lacking in shape retention. Therefore, when repacking, the bag container cannot be kept in a stable shape relative to the bottle to be repacked. For example, there are problems such as easy leakage of liquid and difficult repacking. question.

Therefore, there is a need for a container that can easily refill the contents of the refill container into the bottle to be refilled.

(6) In the SS cap, in order to improve the liquid discharge performance (such as controllability, easy extrusion), a soft object is used for the valve core. For this reason, for example, when the container is shaken or the container is overturned, there is a problem that the valve element is instantly opened due to the impact, and the liquid inside is splashed out.

In order to solve this problem, Patent Document 6 discloses that a shielding member with an opening area smaller than that at the base of the valve body is provided on the liquid injection path closer to the container than the valve body. In the case where such a shielding member is provided, when the container is overturned, the impact of the liquid towards the valve core is limited and the contact with the valve core is eased, thereby preventing the valve core from being accidentally opened.

However, in addition to preventing inadvertent opening of the spool, further improvements are desired in order to reliably prevent liquid from leaking from the spool. In particular, as a container used for shaking, there is a container for a two-layer separation liquid composition containing a two-layer separation liquid composition. This two-layer separation liquid composition separates components with different specific gravity into upper and lower layers at rest, and the container needs to be shaken to mix the two layers during use. Therefore, in the container using the above-mentioned SS cap, further measures against liquid leakage are sought.

Therefore, there is a demand for a container that can reliably prevent the contents from being splashed or leaked even when the container is shaken for use.

(7) A tab for tearing the tab to open the seal is necessary, and a space for accommodating the tab and inserting a finger is required, so the spout portion for pouring out the content liquid inevitably becomes large. The flow rate of the content liquid is restricted to a certain extent depending on the size and shape of the spout, but especially when the content liquid is a high-viscosity content liquid, the discharge becomes poor, and the liquid returned after pouring remains in the sprue. The discharge part may contaminate the periphery of the discharge part, and the contents may drip from the outside of the sprue, and the discharge amount tends to become unstable.

Therefore, in order to solve these problems, such a suck-back inner plug has also been developed. The nozzle of the inner plug is narrowed. The pressure improves the liquid discharge performance, and the residual liquid at the spout is sucked into the container and returned. However, in this suck-back inner plug, since the sprue is thin, there is no space for a pull ring. In order to provide a primary seal, the Increase the number of accessories such a problem.

Therefore, it is desired to have such a container with an inner plug, which has primary sealing performance, good return of the residual liquid in the spout to the nozzle, good liquid discharge, and no contamination around the spout, and no contamination outside the sprue. While the content liquid is dripping, the injection amount of the content liquid is stabilized.

(8) In the existing pouring cap of this type, there is a problem that when pouring out the contents, the contents drip (liquid drips) along the outer surface of the pouring cylinder, and when the dropped contents When it adheres, dries, and solidifies to the fitting part of the upper cover and the cover base, the slipperiness of the surface of the fitting part deteriorates, or the upper cover needs to be opened with a force greater than usual.

Therefore, there is a demand for a container with a lid that can be smoothly opened even if the dripped contents adhere, dry, and solidify.

(9) In the pouring tool described in Patent Document 15, protrusions are formed on the upper surface of the pouring tool main body to prevent liquid from scattering, but liquid remains between adjacent protrusions on the upper surface of the pouring tool main body. , especially when the container is tilted in order to pour out the contents, there is a problem that the liquid remaining between these protrusions leaks out.

Therefore, it is desired that such a container is equipped with a spout plug that reliably removes the content liquid dripped from the spout, prevents the liquid from scattering when the lid is closed, and prevents the content liquid once removed from dripping or leaking. .

(10) In Patent Document 17, it is necessary to have a very high height of the injection cylinder, or to have a special shape in which the axis of the base end and the front end of the injection cylinder are shifted. In addition to the appearance, it will also lead to an increase in cost.

Therefore, it is desirable to have such a container that even if a high-viscosity liquid is injected, the liquid in the content will not remain around the spout or in the spout, so that dripping of the liquid and contamination of the spout can be prevented, and the appearance is consistent with the appearance. The existing impression does not change, and the cheap injection cap.

The engaging state of the shaped body and the ring-shaped connecting part can be smoothly opened. In addition, since the dripped ink flows into the annular space through the notch, a very small amount of ink adhering to the fitting portion between the lid and the base remains.

Furthermore, since the sealing wall erected in the annular space is in contact with the inner wall of the lower end portion of the outer annular body to seal, the waterproof performance of the ink replenishment container is improved.

[Application example 10] The ink replenishment container according to this application example is characterized in that it includes: a container body; a mouth; and a cap disposed on the nozzle main body and having a plug that fits into the pouring cylinder to keep the pouring cylinder in a sealed state, and the cap includes: a base mounted on the nozzle The main body is formed on the top wall through the opening of the injection tube in the state of being installed on the nozzle main body; the cover body is detachably arranged on the base body and provided with the plug part; and hinged The cover body is rotatably connected and held to the base body, a storage space extending along the periphery of the injection cylinder is formed between the base body and the nozzle body, and the base body has at least 1 A slit is opened on the top wall at the periphery of the opening and connected to the storage space.

According to the ink replenishment container of this application example, after the cap is opened and the container is tilted to pour ink, the ink dripped from the spout flows along its inclined direction, but the cap is provided with a connection between the cap and the nozzle body. There are slits in the storage space divided between them, so when the ink is injected, the outflowing ink flows into and is stored in the storage space through the slit. In addition, since the storage space is connected to the outside only through the slit, it is difficult for the ink once stored in the storage space to leak to the outside. Therefore, the ink dripped from the spout can be reliably removed, the ink can be prevented from scattering when the cap is closed, and the ink removed at one time can be prevented from dripping or leaking.

[Application example 11] The ink replenishment container according to this application example is characterized in that it includes a container body and a cap attached to the opening of the container body, and the cap includes: a cap body with the The injection tube of the opening; and the cover, which can be opened and closed connected to the cover body through a hinge, and the injection tube deviates from the direction opposite to the hinge, and the injection tube The communication hole connecting the spout and the container-side opening includes: a straight portion; and a diameter-enlarged portion gradually increasing in diameter from the container-side end of the straight portion toward the container-side opening.

According to the ink replenishment container of this application example, even if high-viscosity ink is poured out, the ink does not remain around the spout or in the spout, and it is possible to prevent dripping of liquid and contamination of the spout. In addition, it is possible to provide an ink refill container having an inexpensive cap with the same appearance as the conventional one.

Detailed ways

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in each of the following drawings, for the convenience of description, the dimensions of each member are shown differently from actual dimensions.

FIG. 1 is a perspective view schematically showing the main configuration of an ink ejection system 1 according to the following embodiment. In addition, in FIG. 1, XYZ axes which are mutually orthogonal coordinate axes are added, and the usage state when the inkjet system 1 is arrange|positioned in the XY plane which coincides with a horizontal plane is shown in figure. In this case, the X axis coincides with the direction in which the carriage 7 is reciprocated, the Y (Y(+)) axis coincides with the direction in which the recording medium P is conveyed, and the Z axis coincides with the height direction of the ink ejection system 1 .

As shown in FIG. 1 , an ink ejection system 1 according to the present embodiment includes a printer 2 and an ink supply device 3 as an example of an ink ejection device. The printer 2 has a control unit 4 and a recording unit 5 . In the printer 2 , the control unit 4 and the recording unit 5 are housed in a casing 6 . The recording unit 5 performs recording with ink on the recording medium P conveyed in the Y-axis direction by a conveying device (not shown). It should be noted that a conveyance device not shown in the figure conveys the recording medium P such as recording paper intermittently in the Y (+) direction. The recording unit 5 is configured to be reciprocable along the X-axis by a moving device (not shown). The ink supply device 3 supplies ink to the recording unit 5 . The control unit 4 collectively controls the driving of each of the above-mentioned components.

The recording unit 5 includes a carriage 7 and a recording head 8 . The recording head 8 is an example of an ink ejection unit, and ejects ink as ink droplets to perform recording on the recording medium P. As shown in FIG. The carriage 7 carries the recording head 8 . It should be noted that the recording head 8 is electrically connected to the control unit 4 . Ejection of ink droplets from the recording head 8 is controlled by the control unit 4 .

The ink supply device 3 has an ink tank 9 . The ink supply device 3 of this embodiment has a plurality (four in this embodiment) of ink tanks 9 . A plurality of ink tanks 9 are accommodated inside the casing 10 . Thus, the ink tank 9 can be protected by the housing 10 . It should be noted that the housing 10 and the housing 6 can be independent or integrated. When the casing 10 is integrated with the casing 6 , the plurality of ink tanks 9 can be housed inside the casing 6 together with the recording head 8 and the ink supply tube 12 .

Ink is accommodated (stored) inside the ink tank 9 . An ink injection portion 11 is formed on the ink tank 9 . In the ink tank 9 , ink can be injected (refilled) into the ink tank 9 from the outside of the ink tank 9 via the ink injection part 11 . It should be noted that the operator can reach the ink injection part 11 of the ink tank 9 from the outside of the casing 10 . In addition, the ink injection part 11 is sealed with a cap (not shown). When injecting (replenishing) ink into the ink tank 9, the operator opens the cap to open the ink injection portion 11, and then injects (replenishes) ink using an ink refill container described later.

An ink supply tube 12 is connected to each ink tank 9 . The ink in the ink tank 9 is supplied from the ink supply device 3 to the recording head 8 via the ink supply tube 12 . Then, the ink supplied to the recording head 8 is ejected as ink droplets from nozzles (not shown) facing the recording medium P side. It should be noted that, in the above example, the printer 2 and the ink supply device 3 are described as separate configurations, but the ink supply device 3 may also be included in the configuration of the printer 2 .

It should be noted that, in this embodiment, the ink supply device 3 is provided on the X(+) side of the printer 2 . However, the installation position of the ink supply device 3 (ink tank 9) is not limited to this, and may be installed on the side of the X (-) side of the printer 2, the side of the Y (+) side of the printer 2 (the side of the front side), etc. .

In the ink ejection system 1 having the above configuration, the recording head 8 is ejected at a predetermined position while the recording medium P is conveyed in the Y-axis direction (Y(+) direction) and the carriage 7 is reciprocated along the X-axis. Ink droplets are ejected, whereby recording on the recording medium P is performed. These operations are controlled by the control unit 4 .

The ink is not limited to either water-based ink or oil-based ink. In addition, the aqueous ink may be any one of an ink having a configuration in which a dissolved substance such as a dye is dissolved in an aqueous solvent, or an ink having a configuration in which a dispersoid such as a pigment is dispersed in an aqueous dispersant. In addition, the oil-based ink may be either an ink having a structure in which a dissolved substance such as a dye is dissolved in an oil-based solvent or an ink having a structure in which a dispersoid such as a pigment is dispersed in an oil-based dispersant.

In this embodiment, an ink replenishment container is used for filling ink into the ink tank 9 . Various embodiments of the ink replenishment container will be described below.

(first embodiment)

Hereinafter, the ink replenishment container 15 according to this embodiment will be described with reference to the drawings. In addition, in each drawing, the same code|symbol represents the same or equivalent component.

2 and 3 are partial sectional views of the ink replenishment container 15 according to this embodiment. Specifically, FIG. 2 is a cross-sectional view showing a state before the lid of the ink replenishment container 15 is opened, and FIG. 3 is a cross-sectional view showing a state after the lid is opened. FIG. 4 is a cross-sectional view showing an example of the seal 104 used in the sealing structure. Fig. 5 is a cross-sectional view showing another example of a seal used in a sealing structure.

In this embodiment, the ink replenishment container 15 is configured as a tube container. As shown in FIG. 2 , the ink refill container 15 is composed of a container body 102 made of soft synthetic resin, a seal 104 that seals the mouth 105 of the container, and a screw that covers the seal 104 and is formed on the outer periphery of the mouth 105 of the container. A cap 103 to which a portion 106 is screwed is formed.

The important feature of the sealing structure of the present invention is that the outer layer 104a of the sealing member 104 is strongly bonded to the inner surface 103a of the top plate of the lid 103, and the inner layer 104c of the sealing member 104 is weakly bonded to the container mouth 105. In the present utility model, expressions such as strong bond and weak bond do not refer to the numerical value of bond strength, but refer to that the bond strength of top plate inner surface 103a/outer layer 104a is greater than inner layer 104c/container mouth The bonding strength of part 105. With such a configuration, the lid 103 is opened in a state where the seal between the inner layer 104c/the mouth portion 105 is peeled off and the seal 104 is bonded to the top plate inner surface 103a when the lid is opened.

Therefore, according to the seal of the present invention, after opening the cap, the cumbersome operation of peeling off the sealing member 104 from the container mouth 105 with fingertips can be completely eliminated. In the sealing material 104 of the present embodiment, synthetic resin coatings are formed on both inner and outer surfaces of the aluminum foil constituting the intermediate layer 104b. The synthetic resin coating formed on the inner and outer sides of the aluminum foil is closely related to the type of resin constituting the lid 103 and the container body 103. The lid 103 and the outer layer 104a need to be made of the same type of resin as each other, and the inner layer 104c and the container body 102 need to be made of the same type of resin. Combination of resins that will not be completely welded even with high-frequency welding treatment, but will cause a false bonded state.

For example, as a general tube container, when the lid 103 is formed of polypropylene resin and the container body 102 is formed of polyethylene resin, it is preferable to use polypropylene for the outer layer 104a, that is, the side in contact with the inner surface 103a of the top plate. As the resinous layer, an unstretched film layer of polypropylene is particularly preferably used. In addition, the inner layer 104c, that is, the side in contact with the container opening 105, preferably uses a peelable resin layer composed of an unstretched film layer of a mixed resin of polypropylene resin and polyethylene resin.

The sealing member 104 of this embodiment is a laminated sheet formed by laminating an intermediate layer 104b, an outer layer 104a, and an inner layer 104c. The intermediate layer 104b is made of aluminum foil, the outer layer 104a is a polypropylene-based unstretched film layer, and the inner layer 104c is a peelable resin layer composed of an unstretched film layer of a mixed resin of a polypropylene resin and a polyethylene resin.

The mixing ratio (weight ratio) when the peelable layer is composed of a mixture of polypropylene and polyethylene is preferably in the range of 90% to 10% of polypropylene and 10% to 90% of polyethylene, particularly preferably 70% to 70% of polypropylene. 30% and polyethylene in the range of 30% to 70%.

In addition, when acidic ink is used, the acid which is its component may contact/react with the aluminum foil via the inner layer 104c, and the aluminum foil may be corroded. Since hydrogen gas is generated due to corrosion of aluminum foil, hydrogen gas enters the container and the container expands, which not only damages the value of the product, but also causes ink to scatter due to rupture.

For these reasons, in the case where an acid is contained as a component of the ink, it is desirable that the coating of the peelable resin layer constituting the inner layer 104c of the aluminum foil constituting the intermediate layer 104b is interposed therebetween by a biaxially stretched polyester film or the like. The polyester resin layer 104d is performed.

It should be noted that the container body 102 of the present embodiment is constituted from the outside to the inside as an olefin resin outer layer/gas (air or oxygen) barrier resin layer/cyclic olefin copolymer layer/olefin resin inner layer layer composition. In this case, the gas-barrier resin layer and the cyclic olefin-based copolymer layer may be interchanged, that is, from the outside to the inside may be an olefin-based resin outer layer/cyclic olefin-based copolymer layer/gas (air or oxygen) Barrier resin layer/Olefin resin inner layer composition. In addition, an oxygen-absorbing resin layer may be included between the cyclic olefin-based copolymer layer and the gas-barrier resin layer. These layers are thermally bonded when there is thermal bonding between the layers, and when there is no thermal bonding between the layers, an adhesive layer is provided between the layers for integration.

As the olefin resin outer layer and inner layer, for example, low/medium/high density polyethylene, linear low density polyethylene, isotactic polypropylene fiber, syndiotactic polypropylene, ethylene-propylene copolymer, polybutene -1. Poly(4-methyl-1-pentene), ethylene-butene-1 copolymer, propylene-butene-1 copolymer, ethylene-propylene-butene-1 copolymer, ethylene-vinyl acetate copolymer Compounds, ionically crosslinked olefin copolymers (ioncrosslinked copolymers), ethylene-acrylate copolymers, etc., may be single or may be a mixture of two or more.

The cyclic olefin-based copolymer layer plays a role in preventing the gas-barrier resin layer from lowering the barrier properties of oxygen in the air due to moisture, and examples thereof include amorphous or low-crystalline copolymers of olefins and cyclic olefins ( COC). As the olefin, ethylene is preferred, but in addition, propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, 3-methyl-1-pentene, 1-carbon Alpha-olefins having 3 to 20 carbon atoms such as alkenes are used singly in combination with ethylene. On the other hand, the cyclic olefin is an alicyclic hydrocarbon compound having an ethylenically unsaturated bond and a bicycle, especially a hydrocarbon compound having a bicyclo(2,2,1)hept-2-ene skeleton.

For the gas (oxygen) barrier resin layer, a thermoplastic resin having a low gas (air or oxygen) permeability coefficient and hygroscopicity is used. For example, the above-mentioned ethylene-vinyl alcohol copolymer is the most suitable, but not limited thereto, nylon 6, nylon 6.6, nylon 6/6.6 copolymer, isophthalic acid, nylon 6 , 10, nylon 11, nylon 12, nylon 13 and other polyamides.

For the oxygen-absorbing resin layer, a resin composition of an oxidizing resin and a transition metal catalyst, or a resin composition of a thermoplastic resin and an oxygen absorber can be used. Here, the oxidizing resin refers to a resin that is oxidized by oxygen in the air through the action of a transition metal catalyst. For example, it is possible to use one that contains carbon side chains and whose main chain contains at least one functional group selected from the group consisting of carboxylic acid groups, carboxylic acid anhydride groups, carboxylate groups, carboxylic acid amide groups, and hydroxyl groups. Resins, polyamide resins, copolymers containing ethylenically unsaturated groups, etc. In addition, the transition metal-based catalyst is a catalyst used in the oxidation reaction of an oxidized resin, and is an organic acid salt or an organic complex salt of a transition metal.

Examples thereof include iron, cobalt, nickel, copper, silver, tin, titanium, zirconium, vanadium, chromium, manganese, etc. Among them, cobalt is particularly preferable because of its high oxygen absorption rate. Furthermore, as the oxygen absorber, almost all conventional oxygen absorbers can be used, but it is preferable to use an oxygen absorber that is practically insoluble in water due to reducing properties, and reduced iron, reduced zinc, reduced tin powder, Ferrous oxide, triiron tetroxide, iron carbide, ferrosilicon, iron hydroxy, iron hydroxide, etc. are used alone or in combination as main components. In addition, a polymer compound having a polyphenol in its skeleton, such as a phenol/aldehyde resin containing a polyphenol can also be used.

The outer peripheral surface of the container mouth 105 of the ink replenishing container 15 is engraved with threads as a threaded joint 106, and corresponding to the threaded joint 106, the inner peripheral surface of the inner cylinder 108 of the cap 103 is engraved with a screw thread as a threaded joint. Section 107 is threaded. Also, the cap 103 may be screwed to the container mouth 105 by screwing in.

And, as described above, the tip of the container mouth 105 is sealed by the sealing member 104 made of metal foil. By filling ink from the bottom of the container (not shown) and finally heat-sealing the bottom of the container, the entire interior of the container main body 102 becomes gas-barrier, and air (oxygen) enters the interior of the container main body 102 to come into contact with the ink. impossible. In addition, when improving the anti-oxidation performance of the ink, it is preferable to provide a check valve (not shown) in the container mouth 105 to prevent air from entering the container body 102 .

In this embodiment, the cover 103 is constituted as a double cylindrical shape of an inner cylinder 108 and an outer cylinder 109, and a screw joint 107 (thread) is engraved on the inner peripheral surface of the inner cylinder 108, so that the cover 103 can be attached and detached. The way of threaded connection to the container mouth 105. Since the material of the cover 103 and the resin constituting the coating layer constituting the outer layer 104a must have thermal fusion properties, the same type of resin is required, and in this example, both are made of polypropylene-based resin.

The outer layer 104a and the inner layer 104c constituting the sealing member 104 are coated separately. Extrusion lamination using a maleic anhydride-modified polypropylene adhesive is suitable for lamination of the outer layer 104a and the intermediate layer 104b (aluminum foil). The lamination of the intermediate layer 104b (aluminum foil) and the inner layer 104c (releasable resin layer), or the intermediate layer 104b (aluminum foil) and the polyester resin layer 104d/inner layer 104c (releasable resin layer) is preferably performed by using polyurethane-based Dry lamination of two-component curing adhesive (Japanese: two-component curing adhesive) is carried out.

The sealing member 104 formed in this way is only required to have a size that completely covers at least the outer diameter of the container mouth 105 to seal, and its shape is generally formed in a substantially circular shape depending on the shape of the container mouth 105 . Therefore, it does not need to have a handle portion for peeling off like the existing sealing member, but is simply cut into a circular shape, so it is easy to manufacture and saves materials.

In the state where the sealing member 104 is arranged at the mouth of the lid, the lid 103 is screwed to the threaded joint 106 (thread) of the mouth of the container 105 in such a way as to cover the sealing portion, and the upper surface 103b of the top plate of the lid 103 is lifted Frequency induction heating. Therefore, in the bonding between the inner surface of the cover 103 and the outer layer 104a, both are made of polypropylene-based resin, so the bonding becomes strong by thermal fusion. On the other hand, in the bonding of the inner layer 104c and the mouth portion 105 of the container, the inner layer 104c is a mixture of polyethylene and polypropylene (mixing ratio = 30:70), and the container main body 102 is made of polyethylene, so dummy Bonded, but its bonded state is weakly bonded. In addition, the false adhesion means the state which has the seal strength of the grade which fulfills the purpose of sealing, and is bonded so that peeling is possible.

In this embodiment, as the most preferable example, polypropylene is used to form the cover 103 and the outer layer 104a of the seal 104 . It should be noted that the strongly bonded cover 103 and the outer layer 104a of the sealing member 104 are preferably made of the same type of resin, and they do not have to be polypropylene as long as a strongly bonded state can be obtained. Also similarly, the inner layer 104c of the sealing member 104 is temporarily bonded to the container mouth 105, but as long as the bonding state is weakly bonded, the inner layer of the sealing member 104 is selected according to the material constituting the container main body 102. layer 104c of resin.

It should be noted that the sealing member 104 of the present embodiment is configured to have a certain thickness. In the state where the sealing member 104 is arranged at the mouth of the cap, when the cap 103 is screwed to the mouth of the container 105 so as to cover the sealing portion At the time of the threaded joint (thread), the sealing member 104 is crushed and deformed by the container mouth 105 and the top plate inner surface 103a of the cap 103, so that sealing can be obtained. In this state, the sealing performance is further ensured by performing thermal fusion and dummy bonding by the above-mentioned high-frequency induction heating.

According to the first embodiment described above, the following effects can be achieved.

According to the ink refill container 15 of this embodiment, since the seal 104 sealing the container mouth 105 is formed on the cap 103 side in a fused state, the seal 104 is peeled off from the container mouth 105 when the cap 103 is opened. Therefore, there is no need to perform the troublesome operation of peeling off the seal after opening the lid like the conventional container with the seal, and it is possible to prevent ink from spilling or scattering due to inadvertent actions and soiling hands and clothes. situation, it is therefore possible to suppress discomfort imposed on the user. Moreover, the sealing member 104 can be cut only according to the shape of the container mouth 105, and there is no need to consider the handle for peeling off, so the production is simple and the material cost is saved.

In addition, this invention is not limited to said embodiment, Various changes and improvements are possible in the range which does not deviate from the summary. Modifications are described below.

In the ink refill container 15 of the first embodiment described above, the tip of the container mouth 105 is sealed by the sealing member 104, ink is filled from the bottom of the container, and finally the bottom of the container is sealed by heat sealing. Here, when performing sealing, decompression sealing may be performed by sealing in a decompression space. In addition, after the ink is filled, the container body 102 may be pressed and the air in the container body 102 may be eliminated as much as possible to seal. By sealing in this way, the quality as degassed ink can be maintained.

(second embodiment)

Hereinafter, the ink replenishment container 15A according to the present embodiment will be described with reference to the drawings.

FIG. 6 is a cross-sectional view of an ink replenishment container 15A according to the second embodiment. FIG. 7 is a cross-sectional view showing the sealing state of the inner plug 202 of the cap 201 . FIG. 8 is a cross-sectional view illustrating a first state during unsealing of the inner plug 202 of the cap 201 . FIG. 9 is a cross-sectional view illustrating a second state during unsealing of the inner plug 202 of the cap 201 . FIG. 10 is a sectional view showing a state of the ink replenishment container 15A in FIG. 9 . FIG. 11 is a cross-sectional view of the ink refill container 15A showing a state where the cap 201 is unsealed and the outer cap 203 is detached.

As shown in FIG. 6, the cap 201 of the ink replenishment container 15A according to this embodiment is a resin molded product attached to the mouth 230a of the container body 230 of the ink replenishment container 15A, and includes an inner plug 202 as the cap body and an inner plug 202 as the cap body. The outer cover 203 of loam cake. The ink refill container 15A accommodates and stores ink through the cap 201 and the container body 230 to which the cap 201 is attached. Note that, for simplicity, only the right half of the cover 201 is shown using a sectional view, but the left half across the rotation axis AX as the central axis also has the same structure as the right side.

As shown in FIGS. 6 and 7 , the inner plug 202 is an integral member in a state before opening such as when the ink refill container 15A is transported, and includes a separating portion 204 , a fitting portion 205 , and a main body side cylindrical portion 206 . Here, the fitting part 205 and the main body side cylindrical part 206 constitute the main body part 220 of the inner plug 202 . The inner plug 202 together with the container main body 230 forms a closed space in which ink is contained in an airtight or liquid-tight manner. In the inner plug 202, the separation part 204 unseals the inner plug 202 along the score 207, that is, an opening is formed by cutting when the inner plug 202 is opened for the first time.

The fitting portion 205 is a fitting member for fitting the inner plug 202 into the mouth portion 230 a of the container main body 230 by plugging (Japanese: plugging). The fitting part 205 is configured to have: an outer cylindrical part 205a, which is fixed in close contact with the peripheral wall of the mouth part 230a of the container body 230; an inner cylindrical part 205b, which is fixed in close contact with the inner wall of the mouth part 230a; and a horizontal part 205c. , close to the mouth portion 230a and connect the outer cylinder portion 205a and the inner cylinder portion 205b. The body-side cylindrical portion 206 has a cylindrical shape as a whole, but has a lip portion 206 a whose diameter increases upward at the upper end to improve liquid discharge when pouring out the ink in the container body 230 .

The outer cover 203 is an integral member made of resin, and includes a side wall 203a, an upper end wall 203b, and a sealing portion 203d. The side wall 203a and the upper end wall 203b form a dome-shaped appearance and protect the inner plug 202 from the external environment of dust, water vapor and the like. The side wall 203a has an internal thread as a threaded portion 211a, and is screwed with an external thread as a threaded portion 211b formed on the side surface of the container body 230 around the rotation axis AX. Thus, the outer cover 203 can be opened/unsealed, and can be attached to and detached from the container main body 230 . Moreover, the inner wall of the sealing part 203d is in close contact with the horizontal part 205c of the fitting part 205 (refer FIG. 9) when closing after opening. Thereby, when closing, the periphery of the main body side cylindrical part 206 is kept liquid-tight, and the outer cover 203 can be plugged.

As described above, in the cap 201, the separating portion 204 of the inner plug 202 has the separating portion side cylindrical portion 204b separated from the main body side cylindrical portion 206 to the inner diameter side by the thickness of the main body side cylindrical portion 206, and on the separating portion side The top wall 204c which seals the upper opening of the cylindrical part 204b is bridged. In addition, a flange 204d extending radially outward is formed at the upper end of the separating portion side cylindrical portion 204b. Furthermore, an annular locking portion 204e for locking the outer cover 203 is formed on the front end side of the flange 204d. A cylindrical first side portion 204f (see FIG. 7 ) extending in the axial direction of the rotation axis AX is provided on the locking portion 204e. It should be noted that the lower end of the separation portion side cylindrical portion 204b and the upper end of the main body side cylindrical portion 206 are connected by a thin-walled notch 207 .

In addition, in the outer cover 203, the upper end wall 203b has an annular protruding portion 209 extending downward on the lower surface thereof, and a claw 209a for engaging with the flange 204d at the time of unsealing is formed at the lower end of the protruding portion 209 . In other words, the upper end wall 203 b is provided with an annular, that is, a cylindrical protrusion 209 , and functions as a holding portion capable of holding the separated separation portion 204 . Furthermore, in the upper end wall 203b as a holding part, an annular rotation restraining part 209b is formed at the front end of the protruding part 209, that is, on the lower end side. rotation. A cylindrical second side portion 209c extending in the axial direction of the rotation axis AX is provided on the rotation suppressing portion 209b. The second side portion 209c is engaged with the separation portion 204 by contacting the first side portion 204f of the separation portion 204 with the outer cover 203 at the reference position before the screwing portion 211a is rotated.

The force for suppressing the rotation of the outer cover 203 by locking the rotation suppressing portion 209 b with the separation portion 204 is determined by assuming a rotational force erroneously applied to the outer cover 203 when the ink replenishment container 15A is transported. In other words, using the force of the separation part 204 to lock the rotation suppressing part 209b, when the unopened ink replenishment container 15A is transported, the restraining force to the extent that the outer cover 203 is not rotated is determined appropriately. Fitting conditions, etc., and the rotation inhibiting portion 209b at the reference position can inhibit the rotation of the outer cap 203 relative to the inner plug 202 with a certain degree of force. This prevents accidental unsealing of the cap 201 in a state where the separation portion 204 is connected to the inner plug 202 before the outer cap 203 is opened.

The cap 201 configured in this way can be rotated by applying a force exceeding the force that prevents the rotation of the outer cap 203 by locking the rotation restraining portion 209 b by the separation portion 204 , so that the ink refill container 15A can be opened. In other words, when the outer cap 203 is rotated with such force, the separating portion 204 can be separated from the main body side cylindrical portion 206 by the upper end wall 203b of the outer cap 203 capable of pressing down the separating portion 204 of the inner plug 202 .

At this time, the separating part 204 can be held on the side of the outer cover 203 by the protruding part 209 formed on the outer cover 203 and the flange 204d formed on the separating part 204, and the outer cover 203 can be unsealed while rotating the outer cover 203. The separation part 204 is separated from the inner plug 202 to form an opening. On the other hand, the lock of the above-mentioned separation part 204 to the rotation suppressing part 209b is released during this unsealing operation. Furthermore, the separating portion 204 is configured to be continuously held on the outer cover 203 side.

Hereinafter, the unsealing operation of the ink refill container 15A by the cap 201 will be described with reference to FIGS. 7 to 11 .

First, as shown in FIG. 7 , in order to separate the separation part 204 of the inner plug 202 from the main body part 220 based on the state where the outer cap 203 is located at the reference position before the rotation of the screw joint part 211a and the cap 201 is sealed, the outer cap 203 rotate clockwise to the tightening direction. At this time, as described above, when the ink replenishment container 15A is normally transported, a force greater than the force applied to the outer cover 203 is required.

As shown in FIG. 8 , when the outer cap 203 is rotated, the protruding portion 209 fits into the flange 204d of the inner plug 202, and the claw 209a engages with the lower peripheral surface of the flange 204d. In other words, the separating portion 204 is held on the outer cover 203 side. At this time, the state in which the rotation suppressing portion 209b is locked by the locking portion 204e is released.

Furthermore, when the outer cap 203 is tightened, the separation part 204 of the inner plug 202 is pressed downward by the upper end wall 203 b of the outer cap 203 . Then, the notch 207 is cut, and as shown in FIGS. 9 and 10 , the separation part 204 is inserted into the main body side cylindrical part 206 of the main body part 220 . In other words, the separation part 204 is separated from the main body part 220 and can be detached from the main body side cylindrical part 206 of the main body part 220 .

In this state, when the outer cap 203 is rotated counterclockwise in the loosening direction, the separation part 204 is detached from the main body side cylindrical part 206 of the inner plug 202 along with the outer cap 203 as shown in FIG. 11 . As described above, the inner plug 202 is unsealed, and the ink in the container body 230 can be poured out from the formed opening OP.

In addition, the outer cover 203 is detachable with respect to the container main body 230 . At this time, since the separation part 204 no longer locks the rotation restraining part 209b, the outer cover 203 can be opened/closed with ordinary force, without requiring a large force like the rotation operation at the time of unsealing. In addition, the separating portion 204 functions as an inner sealing plug capable of closing the opening OP after unsealing.

As described above, in the present embodiment, the upper end wall 203b of the outer cover 203 as the holding portion has the rotation inhibiting portion 209b that engages with the separating portion 204 at the reference position before the screwing portion 211a is rotated. In order to prevent the rotation of the outer cap 203 relative to the inner plug 202, it is possible to prevent accidental unsealing in a state where the separation part 204 is connected to the inner plug 202 in a state before the outer cap 203 is unsealed. In addition, once the seal is opened, the separation part 204 is separated from the inner plug 202 and engaged with the upper end wall 203b, so the locking of the rotation restraining part 209b with respect to the separation part 204 is released, and the rotation of the outer cap 203 with respect to the inner plug 202 is reduced. Easy, so that the outer cover 203 can be easily attached to and detached from the container main body 230 .

In addition, in the unsealing operation of the cap 201, the separation part 204 is cut off from the inner plug 202, so the structure is relatively simple, and the cap 201, that is, the inner plug 202, can be unsealed along with the rotation of the outer cap 203 as the upper cap. The separated part 204 is held by the outer cover 203 after unsealing.

Also, in this case, since the inner plug 202 does not use a tab, it does not cause the tab to break at the welded portion and prevent opening, which may occur when the tab is used to open the seal. In addition, since the inner plug 202 is unsealed by rotating the outer cap 203, it can be easily and reliably unsealed with a smaller force than when the tab is pulled to unseal. Furthermore, after the inner plug 202 is unsealed, the separation part 204 is integrated with the outer cover 203, so that it is not necessary to dispose of it as garbage after unsealed, and the operability is improved.

In addition, in this embodiment, the inner plug 202 is a plug-type composite cap, and is used as a member for air-tightly or liquid-tightly filling ink together with the container main body 230 by using the fitting part 205 . However, it is not limited to the plug, and ink can be filled in an airtight or liquid-tight manner by, for example, sealing by screwing or welding.

In addition, in the said embodiment, the inner plug 202 in which the separating part side cylindrical part 204b was shifted inside rather than the main body side cylindrical part 206 by the wall thickness of the main body side cylindrical part 206 was shown. However, the inner plug 202 may be one in which the separating portion side cylindrical portion 204b is shifted outward by the thickness of the main body side cylindrical portion 206 than the main body side cylindrical portion 206 .

In addition, in the above-described embodiment, a ring-shaped low protrusion seal may be provided on at least one of the outer peripheral surface of the separation portion side cylindrical portion 204 b and the inner peripheral surface of the main body side cylindrical portion 206 . By providing such a seal, a reliable liquid-tight state can be ensured between the separation portion side cylindrical portion 204 b and the main body side cylindrical portion 206 . In other words, liquid leakage can be reliably prevented upon repeated re-use after first unsealing.

<First modified example>

Hereinafter, a cover 251 according to a first modified example of the second embodiment will be described with reference to FIG. 12 .

FIG. 12 is a cross-sectional view showing a cover 251 according to the first embodiment. In addition, in FIG. 12, a part of cover 251 is enlarged and shown.

The cap 251 according to this modified example is the same as the cap 201 in FIGS. 6 to 11 except for the structure of the separating portion 254 of the inner plug 252 and the protrusion 259 of the outer cap 253 . Therefore, illustration and description of the entire cover 251 are omitted.

As shown in FIG. 12 , the cover 251 of this modified example has a structure in which the separation part 254 and the protrusion part 259 are fitted. Hereinafter, the fitting structure will be described in more detail.

First, in the separation part 254, the flange 254d constituting the top wall 254c has a first fitting part 254g having a concavo-convex shape on the first side part 254f of the locking part 254e as the front end part. . As shown in FIG. 12 , the first fitting portion 254g protrudes toward the front end side of the locking portion 254e , that is, outward.

On the other hand, in the protrusion part 259, the rotation suppressing part 259b which comprises the front-end side has the 2nd fitting part 259d which has the corresponding to the 1st fitting part 254g in the 2nd side surface part 259c. Bump shape. In other words, the second fitting portion 259d is recessed toward the inside on the second side portion 259c. The rotation suppression of the outer cover 253 is improved by fitting the 1st fitting part 254g with the 2nd fitting part 259d.

As described above, in this modified example, the cover 251 realizes the function of the cover 251 through the abutment of the first side portion 254f and the second side portion 259c, and the fitting structure of the first fitting portion 254g and the second fitting portion 259d. Rotation of the outer cover 253 during transportation is suppressed. In this case, by appropriately setting the degree of fitting, the locking state of the locking portion 254e and the rotation suppressing portion 259b can be adjusted, so that the rotation of the outer cover 253 can be more reliably suppressed by the rotation suppressing portion 259b. It should be noted that the concavo-convex shape in FIG. 12 has one convex shape on the locking portion 254e side and one concave shape on the protruding portion 259 side, but it is not limited thereto, and various shapes can be applied.

<Second modification>

Hereinafter, a cover 261 according to a second modified example of the second embodiment will be described with reference to FIG. 13 .

FIG. 13 is a cross-sectional view showing a cover 261 according to a second modified example.

The cap 261 according to this modified example is a modified example of the cap 201 of the second embodiment shown in FIG. illustrate.

As shown in FIG. 13 , in the separation portion 264 , at the portion of the flange 264 constituting the top wall 264 c , a locking portion 264 e serving as a front end portion is formed radially inward. Specifically, the locking portion 164e has: a connecting portion CP extending vertically upward from the flat portion FT of the flange 264d; on the first side portion 264f of the protruding portion 269 . In other words, in this case, the first side portion 264f faces the inner side, that is, the rotation axis AX side, unlike the first side portion 204f of FIG. 6 and the like.

Based on the structure of the locking portion 264e described above, the rotation suppressing portion 269b of the protruding portion 269 has a structure in which the second side surface portion 269c faces outward, that is, the side opposite to the rotation axis AX side. In addition, the claw 269a of the protrusion part 269 is formed in the surface of the same side as the 2nd side surface part 269c. Thus, during the unsealing operation, the abutting portion AP of the locking portion 264e is locked by the claw 269a, and once unsealed, the separating portion 264 is separated from the inner plug 262 and engages with the upper end wall 263b.

As described above, in this modified example, the rotation suppressing portion 269b that suppresses the rotation of the outer cap 263 relative to the inner plug 262 is further provided, so that the inner plug 262 can be connected to the separation portion 264 before the outer cap 263 is opened. Prevent accidental opening.

<Third modification>

Hereinafter, a cover 271 according to a third modified example of the second embodiment will be described with reference to FIGS. 14A , 14B, and 14C.

The cover 271 according to this modified example is a modified example of the cover 201 of the second embodiment shown in FIG. 6 , and since the structure is the same as that of the cover 201 in FIG. Diagram and description of the structure.

FIG. 14A is a schematic diagram illustrating a cover 271 according to a third modified example. In addition, FIG. 14A corresponds to the figure which showed the state cut along the X-X cross section perpendicular|vertical to the rotation axis AX in FIG. In addition, in FIG. 7, only the right half part is shown with respect to the X-X cross section, but in FIG. 14, it shows the state including the left half part.

As shown in FIG. 14A , the outer peripheral contour of the flange 274d constituting the separation portion 274 of the cover 271 is polygonal. In other words, the first side portion 274f that is the outer edge of the locking portion 274e has a polygonal shape. Here, as an example, the first side portion 274f is made into a regular octagon. On the other hand, the 2nd side surface part 209c of the rotation suppression part 209b is circular like the case of FIG. 6 etc. FIG. In addition, here, the diameter of the 1st side part 274f and the diameter of the 2nd side part 209c are made substantially the same.

Therefore, as shown in FIG. 14A , the first side portion 274f and the second side portion 209c intermittently abut against each other, and the rotation suppressing portion 209b is locked to the separation portion 274 . In this case, the outer peripheral shape of the first side portion 274f and the inner peripheral shape of the second side portion 209c are different and contact each other, thereby suppressing the rotational movement of the screw coupling portion 211a. It should be noted that the diameter of the inner peripheral contour of the claw 209a engaged with the separating portion 274 is slightly smaller than the diameter of the first side portion 274f, and the separating portion 274 engages with the protruding portion 209 after the unsealing operation.

FIG. 14B is a schematic diagram illustrating another example of the cover 271 according to the third modified example. As in the cover 281 shown in FIG. 14B , contrary to the above, the inner peripheral contour of the rotation suppressing portion 289 b of the protruding portion 289 may be polygonal. In other words, the second side portion 289c, which is the inner edge of the rotation suppressing portion 289b, may be polygonal. Here, as an example, the second side portion 289c is formed into a regular octagon. On the other hand, the 1st side part 204f of the separation part 204 is circular like the case of FIG. 6 etc. FIG. In addition, here, the diameter of the second side portion 289c is set to be substantially the same as the diameter of the first side portion 204f.

Therefore, as shown in FIG. 14B , the first side portion 204f and the second side portion 289c intermittently abut against each other, and the rotation suppressing portion 289b is locked to the separation portion 204 . In this case, the outer peripheral shape of the first side portion 204f and the inner peripheral shape of the second side portion 289c are different and contact each other, thereby suppressing the rotational movement of the screw coupling portion 211a. It should be noted that the diameter of the inner peripheral contour of the claw 289a engaged with the separating part 204 is slightly smaller than the diameter of the first side part 204f, and the separating part 204 is engaged with the protruding part 289 after the unsealing operation.

FIG. 14C is a schematic diagram showing still another example of the cover 271 according to the third modified example. Like the cover 291 shown in FIG. 14C , both the separation portion 294 and the protrusion portion 299 may have a regular octagonal cross-section. In this case, since both are polygonal, the rotation is restricted at a constant angular cycle, so the force for suppressing the rotation of the threaded portion 211a can be further increased, and loosening can be more reliably prevented.

It should be noted that, in the above description, the case where the separation portion and the rotation suppressing portion have a cross-sectional regular octagon has been described as an example, but the cross-sectional shape may be a polygon other than this. In addition, various non-circular shapes are also possible.

In the ink replenishment container 15A of the above-mentioned second embodiment, when the ink is sealed by placing the inner plug 202 in close contact with the mouth 230a of the container body 230 where the ink is injected, it can be sealed in the reduced-pressure space. Perform decompression sealing. By sealing in this way, the quality as degassed ink can be maintained. In addition, when the container body 230 has elasticity, the container body 230 may be pressed to eliminate as much air as possible in the container body 230 during sealing. By sealing in this way, also, the quality as degassed ink can be maintained.

(1) The pouring cylinder may be configured to have a plurality of closing portion insertion portions extending in the axial direction of the central axis C, and the plurality of closing portion insertion portions are respectively closed by the spout closing portions. In addition, instead of forming the pair of sprue ports formed in the blocking portion insertion portion at positions that do not face each other, they may be formed at positions that face each other.

(2) The cross-sectional shape of the pouring cylinder perpendicular to the central axis C is not limited to a circle, and the cross-sectional shape may be a square, a rectangle, a triangle, an ellipse, or the like. As shown in FIG. 27B , the ventilation holes 434c are not limited to arc shapes, and may be formed by arranging holes of any shape such as circles, squares, triangles, and semicircles in an arc shape.

(3) The ink replenishment container to which the plug member is attached does not have to be a thin-walled bottle-shaped container, and the plug member of the present invention may be attached to various other replenishment containers. For example, it is also possible to attach and use a new plug member that covers an outflow port formed by attaching a member made of an injection-molded synthetic resin to a stand-up pouch.

(4) The ink replenishment container 15D in this embodiment replenishes the ink in the ink tank 9 , but is not limited thereto. When refilling another ink replenishment container instead of the ink tank 9, the ink replenishment container 15D can also be used in the same manner as in this embodiment, and the same effect can be obtained. Thus, for example, when replenishment to the ink tank is switched to a new ink replenishment container and the ink tank cannot be replenished with the ink replenishment container 15D, ink can be refilled from the ink replenishment container 15D to the new ink replenishment container. , so that the ink in the ink tank 15D can be replenished without waste.

(sixth embodiment)

Hereinafter, the ink refill container 15E of this embodiment will be described with reference to the drawings.

FIG. 31 is an enlarged cross-sectional view of a main part of an ink replenishment container 15E according to the sixth embodiment, which is partially cut away. FIG. 32 is a partial cross-sectional view showing a state of ink replenishment in the ink replenishment container 15E.

As shown in FIGS. 31 and 32 , the ink refill container 15E of this embodiment has a container main body 501 a filled with ink and an outlet portion 510 , and refills ink into another ink refill container 520 as a container to be replenished.

The outlet portion 510 of the ink replenishment container 15E is provided with: an injection opening cylindrical portion 518 communicating with the container main body 501a; on the same axis; and the flange-shaped portion 511 (base portion). In addition, the injection opening cylindrical portion 518 is erected from the surface of the flange-shaped portion 511 at a distance from the internally threaded cylindrical portion 512 .

And, it is configured that, when replenishing ink in another ink replenishing container 520, the internally threaded cylindrical portion 512 is screwed to the mouth 521 of another ink replenishing container 520, and the surface 511a of the flange-shaped portion 511 is connected to the mouth. The opening end surface 521a of the portion 521 abuts against it.

In addition, in this embodiment, as shown in FIG. 32 , when replenishing ink into another ink replenishing container 520 , it is configured to come into contact with the opening end surface 521 a of the mouth portion 521 in an airtight state. That is, it is configured such that the surface 511 a comes into contact with the opening end surface 521 a in an airtight state by an axial force generated by screwing the internally threaded cylindrical portion 512 and the mouth portion 521 .

In addition, as shown in FIG. 31, the spout part 510 is provided with the main body fixing cylinder part 513 provided perpendicularly to the back surface 511b of the flange-shaped part 511. As shown in FIG. The upper inner surface of the container main body 501 a formed into a bag shape by, for example, a film is fused to the main body fixing cylindrical portion 513 . Here, the inside of the container main body 501a, the inside of the spout opening cylindrical portion 518, and the inside of the main body fixing cylindrical portion 513 communicate with each other.

In addition, as shown in FIG. 31 , the spout portion 510 includes a container cap 519 screwed to the external thread portion 518 a of the spout opening cylinder portion 518 . The container cap 519 is formed with an internal thread portion 519a screwed to the external thread portion 518a of the injection opening cylinder portion 518, and the injection opening cylinder portion is screwed in a state where the external thread portion 518a and the internal thread portion 519a are screwed together. The opening 518A of the opening 518 is closed.

In addition, the flange-shaped part 511, the internal thread cylindrical part 512, and the pouring opening cylindrical part 518 are each integrally formed in the state arrange|positioned on the coaxial line.

Next, a method for replenishing ink from the ink replenishment container 15E configured as described above to another ink replenishment container 520 will be described.

First, the container cap 519 is removed from the spout opening cylindrical portion 518 , and the opening portion 518A of the spout opening cylindrical portion 518 is opened. Next, the internally threaded cylindrical portion 512 is screwed to the mouth portion 521 until the surface 511a of the flange-shaped portion 511 abuts against the opening end surface 521a of the mouth portion 521 in an airtight state, thereby connecting the ink replenishment container 15E to another ink supply container 15E. Ink refill container 520. As a result, the inside of the container main body 501 a communicates with the inside of another ink refill container 520 through the opening 518A and the mouth 521 , and the ink in the container main body 501 a is transferred to another ink refill container 520 .

In the above-mentioned ink replenishment container 15E of the present embodiment, when replenishing ink into another ink replenishment container 520, the internal thread cylindrical portion 512 is engaged with the mouth 521 of another ink replenishment container 520, and the ink is poured out. The open cylindrical portion 518 is inserted into the mouth portion 521 , thereby stabilizing the ink refill container 15E relative to the other ink refill container 520 without dislocation or inclination of the ink refill container 15E relative to the other ink refill container 520 .

In addition, since the pouring opening cylindrical portion 518 is erected from the surface of the container main body 501a at a distance from the internally threaded cylindrical portion 512 , when the internally threaded cylindrical portion 512 is engaged with the mouth portion 521 of another ink replenishing container 520 , the spout opening cylindrical portion 518 can be inserted into the mouth portion 521 without interference.

And because when replenishing ink in other ink refill container 520, be positioned at the flange shape part 511 between injection opening cylinder part 518 and internal thread cylinder part 512 and be constituted with the opening end surface of mouth part 521 in airtight state. 521a, therefore, for example, the replenished ink is high-viscosity ink. When replenishing ink into another ink replenishment container 520, the flange-shaped portion 511 is brought into contact with the opening end surface 521a of the mouth portion 521 in an airtight state. In the state of the other ink replenishment container 520, the air in the container is temporarily flowed into the ink replenishment container 15E by squeezing and deforming the other ink replenishment container 520, and then the negative pressure in the other ink replenishment container 520 when the above-mentioned extrusion deformation is released is released. When the ink in the ink replenishment container 15E is sucked into another ink replenishment container 520 to be replenished, efficient replenishment can be realized.

That is, when the other ink replenishment container 520 is squeezed and deformed with the flange-shaped portion 511 in airtight contact with the opening end surface 521a of the mouth portion 521, the air in the container does not leak to the outside. . Therefore, as described above, when the squeeze deformation is performed, all the air squeezed out from the other ink replenishment container 520 flows into the ink replenishment container 15E. On the other hand, when the squeeze deformation is released, other ink can be replenished. The suction of negative pressure in the container 520 acts on the ink in the ink replenishment container 15E.

In the case where the ink replenishment container 15E is made of a thin film using aluminum, the permeability of gas such as water vapor can be lowered compared with resin, so that the viscosity and degassing of the ink can be maintained. In addition, the ink whose viscosity has been maintained and the ink has been degassed can be replenished to another ink replenishment container, an ink tank, or the like.

Next, a modified example of the present embodiment will be described based on FIG. 33 .

In addition, the same code|symbol is used for the same or equivalent member and part as the said embodiment, and description is abbreviate|omitted, and a different structure is demonstrated.

FIG. 33 is a partial cross-sectional view illustrating a state in which an ink replenishment container 15E according to a modified example of the present embodiment is being replenished.

As shown in FIG. 33 , the spout portion 510 of the ink replenishment container 15E of this modified example includes: a spout opening cylindrical portion 518 ; . The engaging cap member 514 includes a mounting cylindrical portion 514A mounted on the injection opening cylindrical portion 518 , and an inner portion coaxially connected to the radially outer side of the mounting cylindrical portion 514A from the distal end of the mounting cylindrical portion 514A via a connecting portion 514C. The threaded cylindrical portion 514B (engaging cylindrical portion) and the mounting cylindrical portion 514A are configured to abut against the mouth inner peripheral surface 521b of another ink replenishment container 520 when replenishing ink.

The connecting portion 514C is configured to be in close contact with the opening end surface of the mouth when replenishing ink into another ink replenishing container 520 .

In addition, in this modified example, the exhaust groove 515 extending over the entire length in the axial direction is formed on the outer peripheral surface of the attachment cylinder 514A. The exhaust groove 515 penetrates the connecting portion 514C in the thickness direction.

In addition, in this modified example, the sprue opening cylindrical portion 518 is arranged such that the plug body 517 integrally formed inside is extended coaxially. Furthermore, the mounting cylinder portion 514A is formed in a bottomed cylindrical shape including a peripheral wall 514a and a shielding wall 514b extending in a direction perpendicular to the peripheral wall 514a. A spout hole 514c for fitting the plug body 517 in a liquid-tight state is opened in the center portion of the shielding wall 514b. Here, the inside of the ink replenishment container 15E communicates between the plug body 517 and the spout opening cylindrical portion 518 .

In addition, when replenishing ink into another ink replenishing container 520, the internally threaded cylindrical portion 514B and the inner threaded cylindrical portion 514B are arranged in a state where the attachment cylindrical portion 514A is brought into contact with the mouth inner peripheral surface 521b of the other ink replenishing container 520. The other ink replenishment container 520 is relatively moved in the axial direction, and at this time, the spout hole 514c is opened.

In addition, in this modified example, a protruding portion 518b protruding radially inward is formed on the inner peripheral surface of the front end portion of the injection opening cylindrical portion 518 . In addition, the support cylindrical portion 516 is vertically provided on the shielding wall 514b so as to be located between the spout opening cylindrical portion 518 and the plug body 517 . On the outer peripheral surface of the lower end of the support cylinder portion 516, a locking convex portion 516a that is locked to the protrusion portion 518b is formed.

Next, a method for replenishing the ink in the ink replenishment container 15E configured as described above to another ink replenishment container 520 will be described.

First, in a state where the plug body 517 is fitted in a liquid-tight manner to the spout hole 514c of the shielding wall 514b of the engaging cover member 514, the inner peripheral surface of the mouth of the other ink replenishment container 520 and the mounting cylinder 514A are connected to each other. 521b mosaicism. Next, by rotating the pour opening cylinder 518 and the other ink replenishment container 520 to move relative to each other in the axial direction, the pour hole 514c is opened and the opening on the side of the peripheral wall 514a of the exhaust groove 515 is opened. Thus, the inside of the container main body 501a is communicated with the inside of the other ink replenishment container 520 through the gap between the plug body 517 and the injection opening cylinder portion 518 and the injection hole 514c, and the other ink is discharged through the exhaust groove 515. The inside of the supplementary container 520 communicates with the outside.

It should be noted that, as described above, when the spout opening cylinder portion 518 is rotated relative to the other ink replenishment container 520, since the projection portion 518b abuts against the locking convex portion 516a, the direction of the plug body 517 in the axial direction O movement is restricted.

In the above-mentioned ink replenishment container 15E of this modified example, the functions and effects of the above-mentioned embodiment are achieved, and in addition to engaging the internal thread cylindrical portion 514B of the engaging cap member 514 with the mouth portion 521 of another ink replenishment container 520 In addition to the state, since the attachment cylinder portion 514A of the engaging cap member 514 is fitted into the mouth inner peripheral surface 521b of another ink refill container 520, the ink refill container 15E can be further stabilized.

In addition, this invention is not limited to the above-mentioned embodiment and modification, Various changes and improvements can be added to the above-mentioned embodiment and modification. Other modification examples are described below.

(1) In this modified example shown in FIG. 33 , the exhaust groove 515 is formed on the outer peripheral surface of the mounting cylinder portion (peripheral wall 514 a ), but it does not matter if the exhaust groove 515 is not formed.

(2) In this embodiment and this modified example, the mouth portion 521 of the other ink replenishment container 520 is screwed to the engaging cylinder portion, but it is not limited to this, and the following various configurations may be adopted, for example, without The threaded portion for screwing is formed so that the respective surfaces are in contact with each other, a plurality of annular protrusions are formed on the outer peripheral surface of the mouth portion, and a plurality of annular protrusions are formed on the inner peripheral surface of the engaging cylinder portion to be able to contact with the annular protrusion. Fitting protrusions for protrusion fitting, a configuration such that undercut fitting (Japanese: Ander Katto fitting) is possible at a plurality of positions in the height direction, and the like.

(3) In the present embodiment and this modified example, a bag container is used as the ink replenishment container 15E, but a blow bottle container, a tube container, etc. may also be used. In this case, the flange-shaped portion protruding outward in the radial direction from the surface of the container main body 501 a and the lower end portion of the pouring opening cylinder portion constitutes the base portion 511 .

(4) In the present embodiment, the ink refill container 15E is fixed to another ink refill container 520 by screwing the internally threaded cylindrical portion 512 and the mouth portion 521 . However, it is not limited thereto, and may be fixed by engagement or insertion.

(5) In the present embodiment and the present modified example, a mode in which the ink in the ink replenishment container 15E is replenished to another ink replenishment container 520 has been described. However, it is not limited to this, and the ink tank 9 may be replenished with the ink in the ink replenishment container 15E. In this case, as a premise, the ink tank 9 can be separately detached from the ink supply device 3 ( FIG. 1 ). In addition, the ink tank 9 can be deformed by extrusion.

(seventh embodiment)

Hereinafter, the ink replenishment container 15F of this embodiment will be described with reference to the drawings.

FIG. 34 is a side view of an ink replenishment container 15F according to the seventh embodiment. FIG. 35 is an exploded perspective view of a SS cap (self-sealing cap) 601 . FIG. 36 is a longitudinal sectional view of the SS cap 601 . FIG. 37 is a plan view of the SS cap 601 viewed from the tip side.

The ink refill container 15F of this embodiment includes, for example, an SS cap 601 as shown in FIGS. 34 , 35 , and 36 , and a container body 602 to which the SS cap 601 is attached.

The container main body 602 is a squeeze container that can be repeatedly pressed (squeezed), and is molded into a bottle shape by blow molding a soft synthetic resin material such as polyethylene resin, polypropylene resin, polyester resin, etc. component composition. The casing portion 602s standing up in a cylindrical shape from the bottom of the container main body 602 has an elastic restoring force capable of repeated elastic deformation (squeeze deformation). And, for example, the SS cap 601 is attached to the orifice portion 602b located on the upper portion of the case portion 602s by screwing. Therefore, screw threads 602c for fixing the cap main body 603 of the SS cap 601 described later by screwing are formed on the outer peripheral surface of the orifice portion 602b.

It should be noted that the shape of the container main body 602 is not particularly limited, but it is preferably a shape that is easy to grasp during use and hardly causes liquid leakage even if a load is applied. Such a shape is preferably, for example, Use a cylindrical cylinder bottle. Also, since the thickness (resin amount) of the container body 602 affects the ease of pressing (hardness) during use, it is necessary to appropriately select the capacity and resin amount of the container body 602 .

The SS cap 601 is attached to the orifice 602 b of the container body 602 to pour the ink contained in the container body 602 , and includes a cap body 603 fixed to the orifice 602 b of the container body 602 . The cap body 603 is composed of a plastic member formed in a substantially cylindrical shape as a whole so as to close the orifice 602 b of the container body 602 .

In addition, a circular opening 603 a is provided at the tip end of the cap body 603 . Threads 603 b are formed on the inner peripheral surface of the cap body 603 . The SS cap 601 is attached to the orifice 602b of the container body 602 by screwing the thread 603b on the cap body 603 side and the thread 602c on the container body 602 side. In addition, the SS cover 601 is also provided with the plastic outer cover 604 which covers the cover main body 603 in a detachable manner.

Arranged on the inner side of such a cap main body 603 in order from the top end side are: a valve element 605 that opens and closes the slit 605a according to the pressure in the container main body 602 when the container main body 602 is squeezed; an impregnation member 606 that prevents liquid Leakage from the slit 605 a of the valve body 605 ; and the shielding member 607 for adjusting the flow rate of ink flowing from the container main body 602 side toward the valve body 605 side.

The valve element 605 is made of a soft elastic member such as silicone rubber or elastomer. Among them, it is particularly preferable to use silicone rubber which is easy to mold and difficult to tear. The spool 605 has a substantially circular top 605b, a cylindrical skirt 605c that gradually expands in diameter from around the top 605b and descends, and an annular protrusion that expands in diameter from the edge of the skirt 605c toward the outside. The edge portion 605d is integrally formed in the shape of a lid. The slit 605a is composed of a +-shaped slit as shown in FIG. 37, and is formed at the center of the top portion 605b depressed inward.

The valve element 605 fits inside the cap main body 603 in a state where the inside of the recessed part 605e constituted by the top part 605b and the skirt part 605c faces the container main body 602 side. Thereby, the slit 605a of the top part 605b is exposed to the outside from the opening part 603a of the cover main body 603. FIG.

Furthermore, the valve element 605 is fixedly held in the cap body 603 by pressing the flange portion 605d against the inner surface of the cap body 603 by the annular stopper 608 fitted inside the cap body 603 . It should be noted that an opening 608 a having approximately the same diameter as the concave portion 605 e of the valve body 605 is formed at the center of the stopper 608 .

The impregnated member 606 easily absorbs the outflow pressure (shock) of the ink flowing toward the valve element 605 by its elasticity, and therefore has both a shock absorbing function that prevents the outflow pressure of the ink from being directly applied to the valve element 605, and impregnated with ink to prevent the liquid from flowing out. The slit 605a of the spool 605 has a liquid leakage preventing function.

As the impregnation member 606, it is a member that can be impregnated with ink and does not hinder the injection of ink from the slit 605a of the valve body 605 and the introduction of external air when the container main body 602 is squeezed. Mesh, non-woven fabric, fiber body, foam body, porous body, three-dimensional network structure, etc. Among them, it is particularly preferable to use a sponge. In addition, a porous structure made of a polyethylene sintered body can also be used.

It is preferable to use a polyester-based flexible polyurethane foam as the sponge body, and it is particularly preferable to use such a polyurethane foam with a completely open cell structure and to use one that reduces pressure loss.

In addition, in the present embodiment, the number of cells of the sponge body is, for example, preferably 5 to 50 units/25 mm, and more preferably 8 to 40 units/25 mm. In this embodiment, if the number of cells of the sponge body is less than 5/25mm, the effect of preventing liquid leakage becomes insufficient. Performance deteriorates.

In addition, in the present embodiment, the thickness of the sponge is, for example, preferably 3 to 20 mm, more preferably 5 to 10 mm.

It should be noted that the number of cells of the sponge, the thickness of the sponge, and the like can be set to optimum values while verifying through appropriate experiments according to the type of ink, viscosity, and the like.

The impregnating member 606 is preferably arranged in a space formed between the valve element 605 and the shielding member 607 . Specifically, in this embodiment, the impregnating member 606 includes a first sponge 606 a arranged inside the recess 605 e of the valve body 605 and a second sponge arranged between the stopper 608 and the shielding member 607 . Body 606b.

For the shielding member 607, for example, polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS resin, polyoxymethylene (polyoxymethylene) (POM), polyvinyl chloride (PVC), polyparaphenylene, Ethylene dicarboxylate (polyester) (PET), acrylic acid, etc. Among them, polyolefin-based resins such as polyethylene, low-density polyethylene (LDPE), high-density polyethylene (HDPE), and polypropylene are preferably used, and such synthetic resin materials are selected and used according to molding, design, and the like.

The shielding member 607 is integrally formed of a circular bottom wall 607a, a cylindrical side wall 607b standing up from the periphery of the bottom wall 607a, and a flange portion 607c protruding from the peripheral end of the side wall 607b in a radially expanding direction. Formed lid shape.

The shielding member 607 fits the flange portion 607c into the inner peripheral wall 603c inside the cap main body 603 with the inside of the recess 607d formed by the bottom wall 607a and the side wall 607b facing the valve body 605 side. It is fixedly held in the cover main body 603 .

At least one through hole 609 is formed in the side wall 607 b of the shielding member 607 . Specifically, in this embodiment, four through-holes 609 arranged at equal intervals are provided along the periphery of the side wall 607b. And, the inner side and the outer side of the recessed portion 607d of the shielding member 607 are communicated through the plurality of through holes 609 .

When using the ink refill container 15F with the SS cap 601 having the above structure attached, the case portion 602a of the container body 602 is pressed (squeezed) with the orifice portion 602b of the container body 602 facing downward. At this time, the valve element 605 is elastically deformed due to the pressure increase in the container main body 602, and the slit 605a is opened. Thereby, the ink pressurized in the container main body 602 can be poured out from the slit 605 a of the valve body 605 .

On the other hand, when the pressure on the container body 602 is released, the case portion 602a of the container body 602 elastically returns to the original shape. At this time, due to the negative pressure generated in the container main body 602, the valve element 605 is elastically deformed, so that the slit 605a is opened. Thereby, external air can be sucked in through the slit 605 a of the valve element 605 and introduced into the container main body 602 .

By performing the pressing operation as described above, the ink contained in the container body 602 can be poured out from the slit 605 a of the valve body 605 . It should be noted that, in this SS cap, the side slit 605a will not open unless the pressure inside the container body 602 is applied to the valve element 605 to a certain extent. , the ink inside will not leak.

However, in the above-mentioned SS cap 601 , the impregnating member 606 is arranged between the above-mentioned valve element 605 and the shielding member 607 . At this time, when the container main body 602 is shaken repeatedly, since the impregnated member 606 absorbs the outflow pressure (impact) of the ink flowing toward the valve element 605, the outflow pressure of the ink is not directly applied to the valve element 605. The member 606 is impregnated with ink, thereby reliably preventing ink from accidentally splashing or leaking from the slit 605 a of the valve body 605 .

Furthermore, in this SS cap 601, the shielding member 607 adjusts the flow rate of the ink flowing from the container body 602 side to the valve body 605 side, so when the container body 602 is shaken, the impact of the ink toward the valve body 605 is limited, And prevent the spool 605 from accidentally opening due to such an impact.

In particular, as with the above-mentioned shielding member 607, with respect to the bottom wall 607a that directly receives the impact of the ink directed toward the valve body 605, the ink is configured so that the ink passes through the plurality of through holes 609 formed in the side wall 607b from the injection of the ink. When the outflow direction flows into the concave portion 607d in a substantially perpendicular direction, the impact of the ink toward the valve body 605 when the container main body 602 shakes can be more relaxed. In this way, the valve body 605 can be prevented from being accidentally opened, and ink can be reliably prevented from splashing or leaking from the slit 605 a of the valve body 605 .

As described above, in the ink refill container 15F of this embodiment, even if the container body 602 shakes during use, ink can be appropriately injected from the slit 605a of the valve body 605 without liquid leakage. In addition, it is very convenient because it is possible to omit the operation of opening and closing the cover as in the prior art.

Therefore, even when shaking occurs when the ink replenishment container 15F is used, the ink can be properly injected without liquid leakage. In addition, since the operation of opening and closing the cover can be omitted, the safety of the ink replenishment container can be further improved. Usability.

According to the ink replenishment container 15F of the present embodiment, the provision of the impregnating member 606 serves as a resistance when the ink is poured out, thereby preventing ink leakage. In addition, after pouring, the impregnated member 606 absorbs the remaining ink from the impregnated member 606 to the slit 605a serving as the nozzle before the ink drops, so that ink dripping (liquid dripping) can be prevented. Therefore, ink contamination and the like around the slit 605a can also be suppressed.

In addition, this invention is not limited to the said embodiment, In the range which does not deviate from the summary, various changes, improvements, etc. can be implemented.

FIG. 38 is a longitudinal sectional view showing a first modified example of the SS cap 601 . FIG. 39 is a longitudinal sectional view showing a second modified example of the SS cap 601 .

Hereinafter, modification examples will be described including the first modification example and the second modification example shown in FIGS. 38 and 39 .

(1) In the above-described embodiment, the impregnated member 606 is configured to include the first sponge body 606a and the second sponge body 606b. However, it is not necessarily limited to such a configuration. That is, in order to adjust the ink discharge performance (such as controllability, ease of extrusion, etc.), the space formed inside the recess 605e of the valve body 605, the space formed between the stopper 608 and the shielding member 607 can be , and the space formed inside the concave portion 607 d of the shielding member 607 is arranged in any one of the spaces.

For example, in the above-mentioned SS cap 601, as in the first modified example of the seventh embodiment shown in FIG. The second sponge body 606b is disposed between the member 608 and the shielding member 607, and the third sponge body 606c is disposed inside the concave portion 607d of the shielding member 607. In addition, as in the second modified example of the seventh embodiment shown in FIG. 39 , the first sponge body 606 a may be disposed only inside the concave portion 605 e of the valve element 605 .

(2) In addition, in these first sponge body 606a to third sponge body 606c, the number of cells, thickness, etc. may be different. In this case, it is preferable to make the number of cells of the sponge body disposed on the valve body 605 side smaller than the number of cells of the sponge body disposed on the container main body 602 side, whereby a sufficient effect of preventing liquid leakage can be obtained. , without compromising ink discharge.

Fig. 49 is a longitudinal sectional view showing a pouring state. Fig. 50 is a longitudinal sectional view showing a state of sucking back (Japanese: suck bag).

In FIGS. 40 to 45 , 701 is an inner plug, and the inner plug 701 is fitted to the nozzle part 703 of the container main body 702 . The container body 702 is made of plastic, and has a nozzle portion 703 on the top of the case portion 704 via a shoulder portion 705 . On the top of the container body 702 , a cover 706 can be detachably fitted to the shoulder 705 in a state of covering the inner plug 701 from the outside.

The inner plug 701 has a base portion 707 and a sprue portion 708 . The sprue part 708 can open and close the upper surface of the base part 707 . The base portion 707 and the sprue portion 708 are connected by a hinge 711 to form one piece. The hinge 711 is a member configured to be flexible by using a thin resin material.

The base 707 is concentrically arranged with an inner cylinder 712 and an outer cylinder 713 . The outer cylinder 713 is coupled to the inner cylinder 712 via a shoulder 714 . When installing the inner plug 701 by fitting the nozzle part 703 of the container main body 702, between the inner cylinder 712 and the outer cylinder 713, insert the front end 715 of the nozzle part 703 until it touches the bottom of the shoulder 714. surface. Then, the engaging portion of the outer cylinder 713 is fitted into the engaging portion of the front end 715 of the nozzle portion 703 to be fixed.

The inner surface of the inner cylinder 712 of the base 707 forms a fluid passage 718 through which ink flows. The fluid passage 718 is closed by a thin-walled partition 720 of the fluid passage 718 in a non-use state. Scores 722 are formed on the separator 720 along the outline of the nozzle 721 to be formed. The pull ring 724 is coupled to the inside portion of the score 722 of the separator 720 , ie, the cut-out portion 723 , by a rod 725 . At least a portion of the tab 724 enters the fluid passage 718 formed by the inner barrel 712 .

The nozzle part 708 is comprised from the cylindrical part 728 and the top plate part 727 which closed the upper end. In the sprue portion 708 , a sprue nozzle 726 stands up from the center portion of the top plate portion 727 . The sprue nozzle 726 communicates with the fluid passage 718 . The opening area of the sprue nozzle 726 is smaller than the opening area of the fluid passage 718 .

The function of the inner plug 701 constituted in this manner is as follows.

When injecting the ink in the container main body 702, first, as shown in FIGS. 42 and 43 , the cover 706 is removed to expose the inner plug 701 .

Next, as shown in FIGS. 44 and 45 , the sprue portion 708 of the inner plug 701 is rotated by 180° relative to the hinge 711 to open. Thus, the tab 724 in the fluid passage 718 of the base 707 is exposed. As shown in FIG. 46 and FIG. 47 , if the finger is caught on the pull ring 724 and pulled up, the pull-up force is transmitted to the cut-out portion 723 of the partition 720 via the rod 725 , and the notch 722 is broken. When the tab 724 and the cut-out portion 723 are removed, the sprue 721 is opened. In this state, the sprue part 708 is rotated in the original direction relative to the hinge 711 to close the base part 707 . Thereby, the spout nozzle 726 communicates with the inside of the container main body 702 via the spout 721 , so that ink can be poured out.

Therefore, as shown in FIG. 48 and FIG. 49, when the container main body 702 is grasped and pressed by hand, and a squeeze action is applied, the ink 731 of the container main body 702 passes through the fluid passage 718 of the base portion 707 of the inner plug 701 from the nozzle part. The front end 723 of the sprue nozzle 726 of 708 injects.

When the injection of the predetermined amount of ink 731 is completed, if the squeezing action of the hand is stopped, the shape and volume of the container main body 702 will recover. As shown in FIG. Inside the container body 702.

According to the eighth embodiment described above, the following effects can be obtained.

(1) According to the ink replenishment container 15G of the present embodiment, the spout nozzle 726 is narrowed in the inner plug 701 so that the suction effect can be exerted by squeezing, so that the ink 731 does not remain on the spout nozzle 726, and Drainage becomes good. Therefore, the periphery of the sprue nozzle 726 is not soiled, the ink 731 does not drip to the outside of the sprue nozzle 726, and the discharge amount can be stabilized.

(2) According to the ink replenishment container 15G of the present embodiment, in the inner plug 701, the partition 720, the notch 722, and the pull ring 724 can be provided in the large-diameter fluid passage 718 of the base portion 707 of the inner plug. It has the function of primary sealing (Japanese: バージンシール).

(3) According to the ink replenishment container 15G of the present embodiment, for having the above-mentioned function, since it is solved by only increasing the number of parts of one part in the inner plug, the productivity of the inner plug will not be greatly reduced, and the material The volume increase is also very small.

(4) According to the ink replenishment container 15G of this embodiment, even if it is used in the case of a rigid large container that cannot exert the suction effect even by squeezing, in the inner plug of the present invention, the sprue is made thinner, So it drains well.

In the inner plug 701b, the sprue 721 is elongated and its longitudinal direction is perpendicular to the rotation direction of the sprue portion 708 when opening and closing, that is, parallel to the axis 733 of the hinge 711 .

In addition, the widths d1 and d2 of the sprue 721 are changed at both ends in the lengthwise direction so that d1>d2. In this way, by changing the tilting direction of the container main body 702, it is possible to select whether to flow the ink 731 mainly in the part of the width d1 of the spout 721 or mainly in the part of the width d2 when the ink 731 is poured out. Flow, you can choose the injection volume. At this time, as shown in FIG. 55 , if a display 734 such as "more-less" is displayed on the surface of the sprue nozzle 726 corresponding to the direction of inclination, selection of the direction of inclination will be facilitated.

It can be clearly seen from the above description that according to this utility model, it has primary sealing performance, and in addition, the liquid discharge is good, and the residual liquid after injection can be returned to the nozzle well, and there is no pollution around the injection part and no leakage. Ink drips from the outside of the spout, and an ink refill container with an inner plug that stabilizes the amount of ink poured out can be realized.

The top wall 803b is integrally connected to the upper end of the peripheral wall 803a to close the opening of the mouth and neck portion 801a of the outer container 801 . The pouring cylinder 803c stands at the center of the top wall 803b, and the ink in the container can be poured out through the hole.

In addition, reference numeral 804 is a lid body, which is openably and closably connected to the base body 803 via a hinge 805 , and is matched with the upper surface edge of the base body 803 to close the opening of the pouring cylinder 803c.

The cover 804 is composed of an outer annular body 804a, an inner annular body 804b, and a top plate 804c. The outer annular body 804 a has a lower end surface along the edge portion of the upper surface of the base body 803 . The inner annular body 804b is disposed inside the outer annular body 804a, surrounds the injection tube 803c, and forms a downwardly open annular space 806 between the outer annular body 804a and the outer annular body 804a. The top plate 804c is integrally connected to the upper ends of the outer annular body 804a and the inner annular body 804b, and cooperates with the outer annular body 804a and the inner annular body 804b to form a storage space for the pouring cylinder 803c.

In addition, reference numeral 807 is a handle provided on the front side of the cover body 804 (position facing the hinge 805 ) and on the upper part of the outer surface of the outer annular body 804 a. In addition, reference numeral 808 is a cylindrical body that is held down on the back surface of the top panel 804c of the cover body 804 . The cylinder body 808 is a member that fits into the opening of the spout cylinder 803c when the lid body 804 is closed, thereby preventing ink from flowing out.

In addition, reference numeral 809 is an annular sealing wall integrally provided at the edge portion of the top wall 803 b of the base body 803 and standing in the annular space 806 . The annular sealing wall 809 maintains the inner side of the lid body 804 in a sealed state by contacting (surface-contacting) the inner side wall of the lower end portion of the outer annular body 804a.

The ring-shaped sealing wall 809 has a contact surface with the inner side wall of the lower end of the outer ring body 804a, so that water etc. can be reliably prevented from entering the cap (improved waterproof performance).

Reference numeral 810 is an annular connection portion integrally provided on the top wall 803 b of the base body 803 inside the sealing wall 809 . The annular connection portion 810 is detachably engaged (fitted by snapping) to the inner annular body 804 b of the cover 804 , thereby connecting the cover 804 to the base 803 . As the annular connection portion 810, a concave portion provided on the lower end portion of the inner annular body 804b, or a convex portion or a concave portion suitable for a convex portion (the illustrated member is shown as a convex portion) can be applied.

Reference numeral 811 is a notch formed in the inner annular body 804b. As an example, the notch portion 811 is formed to have a notch end 811a with an open lower end, and is adjacent to the front side of the inner annular body 804b, that is, the side where the handle portion 807 is provided. Through this notch 811, the inner annular body 804b becomes discontinuous, and the engagement of the inner annular body 804b with the annular connection portion 810 becomes easy to release, and even if a drop falls into the position where the lid body 804 and the base body 803 are engaged, The ink adheres, dries, and solidifies, and the lid 804 can be opened and closed smoothly. In addition, when liquid dripping occurs, the ink flows out into the annular space 806 through the cutout portion 811, so that the amount of ink adhered can also be reduced.

In this example, the case where one notch 811 is provided near the side where the handle 807 is provided is shown, but as long as the cover 804 can be fitted to the base 803 while maintaining the desired strength, the notch 811 The formation position of the inner annular body 804b can be appropriately changed to the side or rear side of the inner annular body 804b, and is not limited to the illustrated form. In addition, the number, width, and shape of the cutouts 811 can also be appropriately changed.

It should be noted that at least two cutouts 811 can be provided at intervals. In this case, the inner annular body 804b located between the cutouts 811 can easily bend itself, so the cover 804 can be opened smoothly. In addition, on the other hand, when the cover body 804 is closed, the inner annular body 804b, that is, the inner annular body 804b located between the cutouts 811 is connected to the annular connecting portion 810, so that the pair of inner annular bodies 804b The engagement of the connection part 810 becomes more reliable.

Reference numeral 812 is an annular storage groove provided on the top wall 803 b of the base body 803 between the seal wall 809 and the annular connection portion 810 . This storage groove 812 enters the lower end portion of the inner annular body 804b, and stores ink flowing out through the cutout portion 811 (dropped ink).

The main part of the storage groove 812 is enlarged. As shown in FIG. The groove width of the gap t prevents the ink passing through the notch 811 from flowing back to the back of the inner annular body 804 b and flowing out to the seal wall 809 by the gap t.

In addition, reference numeral 813 is an inner plug disposed between the protruding end portion of the mouth neck 801a of the outer container 801 and the top wall 803b of the base body 803, sandwiched and fixed by the mouth neck 801a and the top wall 803b.

The inner plug 813 is comprised from the partition wall 813b, the cylinder part 813c, and the fitting cylinder 813d. The partition wall 813b leaves a through opening 813a connected to the opening of the injection cylinder 803c, and closes the opening of the mouth and neck portion 801a of the outer container 801 . The cylinder body 813c is integrally connected to the upper surface of the outer edge of the partition wall 813b, and its upper end can abut against the top wall 803b of the base body 803 . The fitting cylinder 813d is integrally provided on the outer edge of the lower surface of the partition wall 813b, and can be fitted to the inner wall of the mouth and neck portion 802a of the inner container 802. As shown in FIG.

Reference numeral 814 is a spool that keeps the through-hole 813a of the inner plug 813 in a closed state, and squeezes the case portion of the outer container 801 to open the through-hole 813a, thereby allowing the ink to flow out toward the spout cylinder 803c. . The spool 814 is, for example, composed of a cylinder 814a and a valve portion 814b (for example, a three-position valve). The upper end portion and the lower end portion are respectively fitted into and fixed to the annular recessed portion 813e of the cylindrical body 813e, and the valve portion 814b is supported by the inner wall of the cylindrical body 814a via an elastic arm. It should be noted that the spool 814 is not limited to the illustrated configuration.

Reference numeral 815 is a suction storage chamber provided on the lower surface of the partition wall 813b of the inner plug 813 having an opening 815a opened in the partition wall 813b. The storage chamber 815 is hung and held on the lower portion of the partition wall 813b, and is composed of a storage chamber main body 815b and a slider (for example, a sphere) 815c. The storage chamber main body 815b is formed as a bottomless cylindrical peripheral wall forming a storage space for residual ink inside the partition wall 813b.

The slider 815c is formed to be movable toward and away from the opening 815a in the storage space of the storage chamber main body 815b, and by moving in a direction away from the opening 815a, residual ink is sucked into the storage space through the opening 815a. It should be noted that the storage chamber 815 may be an integrally connected component, or may be a combination of different components. In addition, the storage chamber 815 may be erected on the upper portion of the partition wall 813b. The opening 815a may be partially covered by the spool 814, but may not be completely closed by the spool 814, but may be always open.

In addition, reference numeral 816 is at least one protrusion provided at the upper end portion of the peripheral wall forming the storage chamber main body 815b and preventing the slider 815c from being pulled out from the opening 815a. Reference numeral 817 is an end opening provided at a lower portion of the storage chamber 815b.

The size of the end opening 817 is smaller than that of the slider 815c and allows the slider 815c to move within the range of the protrusion 816 and the end opening 817 .

When injecting ink, if the container body 800 is tilted or turned upside down, the slider 815c moves to be closest to the opening 815a. On the other hand, when the injection of ink is completed and the container body 800 is returned to the upright position, the slider 815c moves away from the opening 815a due to its own weight or the negative pressure generated by the restoring force of the inner container 802. , that is, moves toward the end opening 817, and at this time, the residual ink present on the upper surface of the partition wall 813 is sucked into the storage space of the storage chamber 815 through the opening 815a, thereby avoiding liquid dripping.

A slight gap may be formed between the slider 815c and the peripheral wall forming the storage chamber main body 815b, but the gap is set so that the residual ink does not pass through the gap due to consideration of the surface tension of the ink, and the residual ink is reliably contained in the gap. The accommodating space can prevent ink (residual ink) that has been in contact with the outside air from entering the container main body 800 through the storage chamber main body 815b.

The slider 815c can be made of a synthetic resin or a metal member, and in the case of using a metal member in particular, it can move smoothly by its own weight and can further enhance the suction effect. When the slider 815c is made of a metal member, its surface can be covered with resin, thereby stably maintaining the quality of the ink.

In this example, the slider 815c is shown as a spherical body as an example, but its shape can be appropriately changed as long as it can move smoothly in the storage chamber main body 815b, and is not limited to the illustrated structure. It should be noted that the slider 815c is designed such that the ink and/or air cannot pass through the slider 815c and substantially flow into the inner container 802 .

In addition, reference numeral 818 is an external air introduction hole provided at least one position (preferably two positions) of the step portion of the top wall 803 b of the base body 803 and connecting the inside and outside of the base body 803 . In addition, reference numeral 819 is a horizontal opening provided on the mouth and neck portion 801 a of the outer container 801 and connected to the inner container 802 . In addition, reference numeral 820 is a through path provided in the cylindrical portion 813 c of the inner plug 813 . In addition, reference numeral 821 denotes a vertical groove provided on the outer wall of the mouth and neck portion 801 a of the outer container 801 .

When external air enters the base body 803 through the external air introduction hole 818 , the external air is introduced between the inner container 802 and the outer container 801 through the through path 820 , the vertical groove 821 and the opening 819 .

In addition, reference numeral 822 is an external air introduction valve integrally connected to the outer side wall of the cylindrical body 814a constituting the valve body 814 in a cantilevered state. The free end of the external air introduction valve 822 is constituted by a disk-shaped elastic tongue, and the elastic tongue is in detachable contact with the valve seat portion 803e provided on the lower surface of the top wall 803b of the base body 803, and the external air The gas introduction hole 818 remains closed.

The external air introduction valve 822 is a part that opens when the force (force for squeezing) applied to the casing portion of the outer container 801 is removed to return the outer container 801 to its original shape, and the air is passed to the inner container 802 and the outer container. 801 is introduced with external air, the outer container 801 quickly returns to its original shape, and remains closed when the inner container 802 is squeezed by a squeezing action, so that the ink filled in the inner container 802 is reliably discharged.

The external air introduction valve 822 and the valve element 814 can be integrally connected to each other via the cylinder body 814a, thereby reducing the number of components. However, the external air introduction valve 822 and the valve element 814 may be composed of different components, and this point is not limited. .

In the ink refill container 15H which is a squeeze container formed as described above, when the ink filled in the inner container 802 is poured out, the container main body 800 is held in an inclined and inverted posture and the casing portion of the outer container 801 is squeezed. . In this way, along with this operation, the volume of the inner container 802 is reduced (reduced), and the ink filled therein is discharged from the opening of the spout cylinder 803c through the neck portion 802a and the through opening 813a of the inner plug 813 . At this time, the slider 815c is located near the opening 815a (the portion where the protrusion 816 is provided).

When the extrusion action is stopped, the through port 813a is immediately kept closed by the valve core 814, and the elastic tongue of the external air introduction valve 822 is separated from the valve seat portion 803e formed on the top wall 803b to open the external air introduction hole 818. Therefore, by introducing external air between the outer container 801 and the inner container 802, the outer container 801 quickly returns to its original shape (shape before destruction).

When the container main body 800 is returned to the upright posture (standing posture) in conjunction with the stop of the squeezing operation, while the slider 815c is moving toward the distal end opening 817, the amount remaining in the space from the injection cylinder 803c to the valve body 814 is The ink is sucked into the accommodation space of the storage chamber 815 by sucking back accompanying the movement of the slider 815c.

The amount of suction of ink is determined by the amount of movement of the slider 815c and the volume of the storage space, and is appropriately set.

It should be noted that, as described above, in FIG. 56 and FIG. 57 , as an example, the outer container 801 is constituted by the outer layer body and the inner container 802 is constituted by the inner layer body. The ink replenishment container 15H is a layered squeeze container whose volume is reduced by peeling the inner layer body (inner container) 802 from the outer layer body (outer container) 801 . However, the present invention can be applied to a double container in which the inner container 802 filled with ink is assembled inside the outer container 801, or a single-layer container without an inner container, and is not limited to the illustrated configuration.

In addition, as described above, in the embodiment, the case of applying the storage chamber 815 in which the storage space is formed by the bottomless cylindrical peripheral wall provided with the terminal opening 817 in the lower part of the storage chamber main body 815b is shown, but as the storage chamber 815, Parts with a bottom can also be used.

(eleventh embodiment)

Hereinafter, the ink replenishment container 15J of this embodiment will be described with reference to the drawings.

FIG. 63 is a cross-sectional view showing the cap 110 of the ink refill container 15J according to the eleventh embodiment.

The ink replenishment container 15J of the present embodiment is roughly configured to include a container body 190 filled with ink, and a cap 110 for injecting ink. The ink pouring cap 110 has a cap body 120 attached to an opening 191 of the container body 190 , and a cover 140 connected to the cap body 120 via a hinge 130 so as to be openable and closable.

The cover 110 can be manufactured using common plastic materials such as polypropylene by injection molding, compression molding and other well-known manufacturing methods, and usually the cover body 120, the hinge 130, and the cover 140 are integrally formed.

In the ink refill container 15J using the pouring cap 110 of this embodiment, the container body 190 is not particularly limited, but when the viscosity of the ink is high, it is preferable to use a squeezable soft plastic container. In addition, the ink refill container 15J is provided in a state in which, after filling the container body 190 with ink, the opening 191 is heat-sealed with an aluminum foil film, and the cap 110 is attached to the sealed opening 191 .

When using the ink refill container 15J, the user temporarily removes the cap 110 from the container body 190 , peels off the aluminum foil film from the opening 191 of the container body 190 , unseals it, and reattaches the cap 110 for use.

The lid main body 120 has: a top plate 150 sealing the opening 191 of the container main body 190; an outer cylinder 160 hanging from the outer peripheral edge of the top plate 150 and engaging with the outer peripheral edge of the opening 191 of the container main body 190; and a pouring cylinder 170, It protrudes from the top plate 150 and communicates with the inside of the container.

The pouring cylinder 170 is offset in the direction opposite to the connection side of the hinge 130 , and in this embodiment, the centerline of the pouring cylinder 170 is eccentric from the centerline of the cap main body 120 . Thereby, when injecting high-viscosity ink, the inclination of the container can be reduced, the injection cylinder 170 is not blocked by the cover 140 and can be easily recognized visually, and the top plate 150 is less likely to be contaminated by ink.

In addition, in this embodiment, an internal thread 161 is provided on the inner side wall of the outer cylinder 160 , and is screwed into the container body 190 until the lower surface of the top plate 150 abuts against the top surface of the opening 191 of the container body 190 .

The communication hole connecting the spout 171 provided at the front end of the spout cylinder 170 to the container-side opening 172 has a straight portion 173 with an approximately constant inner diameter, and an enlarged diameter portion 174 extending from the container-side end of the straight portion 173 toward the container The diameter of the opening 172 gradually expands. The end edges of the spout 171 and the container-side opening 172 may be suitably chamfered or rounded.

As described above, when the user finishes pouring the ink, he stops squeezing the container and returns the container to the original posture. At this time, the ink from the vicinity of the sprue port 171 to the communication hole of the spout cylinder 170 is recovered into the container main body 190 by its own weight and sucked back, and when the viscosity of the ink is high, it tends to remain easily. Therefore, there is a possibility that ink may drip from the spout 171 to contaminate the surroundings, or may be fixed in the communication hole to deteriorate the pourability.

In this embodiment, by configuring the pouring cylinder 170 as described above, and specifying the inner diameter of the straight portion 173, the cap 110 can be obtained that is excellent in the ink pouring property, and also excellent in the liquid discharge property and the liquid return performance after the pouring. .

Regarding the inner diameter D of the straight portion 173, the smaller the inner diameter D, the higher the liquid return effect by sucking back, but if it is smaller than a specific range, the pourability will deteriorate, and the liquid tends to remain near the spout 171 . In addition, the larger the inner diameter D of the straight portion 173, the higher the liquid return effect by its own weight, but if it is larger than a specific range, the suckback is difficult to occur, and the liquid tends to remain on the peripheral wall in the communication hole. It should be noted that the inner diameter D of the straight portion 173 can be set in an appropriate specific range according to the viscosity of the ink to be filled.

In addition, by providing the diameter-enlarged portion 174 gradually increasing in diameter from the container-side end of the straight portion 173 to the container-side opening 172 , the liquid return effect due to its own weight can be enhanced.

The larger the opening diameter of the container-side opening 172 is, the better it is within the range in which the container-side opening 172 does not reach the contact position with the top surface of the opening 191 of the container body 190, but if it exceeds this range, the top plate 150 will be damaged. A gap may be generated between the lower surface and the top surface of the opening 191 of the container main body 190, and the sealing of the container may become incomplete. It should be noted that the taper angle θ1 of the enlarged diameter portion 174 shown in FIG. 63 can be appropriately set according to the relationship between the viscosity of the ink, the height of the spout cylinder 170 , and the amount of eccentricity d.

It is important for the straight portion 173 to have a predetermined length in order to obtain stable pourability while improving the liquid return effect by sucking back. The ratio of the length L of the boundary from the spout 171 to the diameter-enlarged portion 174 to the length h of the communication hole can be set while balancing the stable pourability and the liquid return effect by sucking back.

The injection cylinder 170 of this embodiment is basically cylindrically symmetrical, and its height is the same as that of the prior art, so the manufacturing cost of the molding die will not be increased.

The cover 140 of this embodiment has: a top cover part 141 that covers the entire top plate 150 of the cover body 120 when the cover cover 140 is closed; a sealing part 142 that fits into the spout 171 at the front end of the spout cylinder 170 to seal; and The engaging portion 143 is engaged with the cover body 120 to lock the cover 140 . A flange-shaped finger hook 144 protrudes from a side of the outer periphery of the top cover portion 141 opposite to the position where the hinge 130 is connected.

Corresponding to the engaging portion 143 of the cover 140 , a rising portion 180 is provided on the outer peripheral edge of the upper surface of the top plate 150 of the cover body 120 . An engaging portion 181 engaged with the engaging portion 143 of the cover 140 is provided on the outer peripheral side of the standing portion 180 . In addition, in order to improve the operability of the finger hook 144 , the outer cylinder portion 160 of the cover body 120 is formed with a very thin step portion 162 at a corresponding position.

In the existing hinged lid of this type, a knob-shaped (Japanese: コブ-shaped) protrusion with a large diameter is provided in the middle of the sealing part, and this part is fitted into the injection cylinder to lock the cover, especially when the viscosity is high. Lots of contents with a hinged lid. In the case of such a configuration, for example, if ink remains in the spout cylinder and is fixed around the locking portion, the opening and closing operation of the cover may be hindered.

In the present invention, the engaging portion 143 is provided separately from the sealing portion 142 , and the sealing portion 142 is slidably contacted with the straight portion 173 in the pouring cylinder 170 having a cylindrical shape or the like to seal the spout 171 . With this configuration, even if ink remains in the pouring cylinder 170, the sealing portion 142 does not stick, and the cover 140 can always be opened and closed smoothly.

In addition, since the inner side wall of the rising portion 180 is formed as the inclined surface 182 that rises smoothly by an angle θ2 from the plane formed by the top plate 150 , even if ink spills and adheres to the top plate 150 , it can be easily wiped off. It should be noted that the angle θ2 can be appropriately set.

In the present embodiment, the standing portion 180 is provided over the entire circumference, but may be provided only at a position corresponding to the engaging portion 143 of the cover 140 .

The ink replenishment container 15J of the present embodiment is particularly effective for relatively high-density ink, but can also be effective for normal-density ink.

The configuration and operation of the ink replenishment container have been described above, but the method described below can also be used.

As described above, from the ink refill container 15 of the first embodiment to the ink refill container 15D of the fifth embodiment, and from the ink refill container 15F of the seventh embodiment to the ink refill container J of the eleventh embodiment The ink refill container refills the ink tank 9 with ink. However, the present invention is not limited thereto, and when replenishing ink to another ink replenishment container instead of the ink tank 9, it is also possible to use each of the above-mentioned ink replenishment containers and perform the same method as the present embodiment, and can have the same effect. Thus, when the ink tank cannot be replenished with the previous ink replenishment container and the new ink replenishment container is switched to replenish the ink tank, ink can be refilled from the previous ink replenishment container to the new ink replenishment container , so that the previous ink can be used to replenish the ink in the container without waste.

As described above, in the ink refill container 15 of the first embodiment to the ink refill container 15J of the eleventh embodiment, each ink refill container is filled with ink. However, the present invention is not limited thereto, and a cleaning agent may be filled instead of ink.
