Disclosure of Invention

Problems to be solved by the invention

The bag portion of the liquid cartridge containing the liquid has low rigidity and may be damaged during transportation or storage. In order to suppress such damage, it is conceivable to transport and store the liquid cartridge in a box, but in the case of the liquid cartridge of patent document 1, in which the container, the pump, and the nozzle are integrated, there is a problem that a large number of dead spaces are required when the liquid cartridge is stored in the storage box, and the storage box becomes large.

On the other hand, the support shown in fig. 1 of patent document 2 is not intended to protect the bag (bag portion) during transportation or storage, but is supposed to be reinforced since it covers the bag itself. However, since the support body of patent document 2 has a structure in which the entire front surface is opened and closed, when the bag expands due to a change in air pressure, a change in temperature, or the like during transportation or storage, the entire front surface is opened, and the bag may be exposed. Therefore, even if the support of patent document 2 can be used for protecting the bag during transportation or storage, the bag may be damaged during transportation or storage.

The present invention relates to a liquid cartridge storage container capable of suppressing damage to a liquid storage portion of a liquid cartridge.

Means for solving the problems

The invention relates to a liquid cartridge container, comprising: a liquid cartridge having a liquid storage portion capable of storing liquid; and a storage container into which the liquid storage portion of the liquid cartridge can be inserted and removed, the liquid storage portion having flexibility expandable in accordance with a change in volume of the stored content, the storage container comprising: a container body having a storage space capable of storing at least a part of the liquid storage section and an insertion hole for inserting and taking out the liquid storage section into and from the storage space; and a lid portion that is provided to the container body so as to be rotatable via a hinge portion, and opens and closes the insertion hole by rotating about the hinge portion, wherein the hinge portion is located on an upstream side in an insertion direction of the liquid storage portion with respect to the storage space with respect to a most expanded point of the liquid storage portion in a state of being stored in the storage space.

Detailed Description

Hereinafter, preferred embodiments for carrying out the present invention will be described with reference to the drawings. The following embodiments do not limit the inventions of the claims, and all combinations of features described in the embodiments are not necessarily required for the solution of the invention.

[ liquid box Container ]

As shown in fig. 1 and 2, the liquid cartridge container 1 of the present embodiment includes a liquid cartridge 10 in which a liquid is stored and a container 50 for protecting the liquid cartridge 10.

[ liquid box ]

The liquid cartridge 10 is a disposable container that is replaceably attached to a device to be supplied with a liquid, and the usage thereof is not particularly limited, but in the present embodiment, it is a liquid cartridge for an electrospinning device used in an electrospinning device.

Here, the electrospinning device is a device that ejects the spinning liquid toward the object by the electrostatic spraying method. The electrostatic spraying method is a method in which a spinning liquid is electrostatically charged (electrostatically charged) by applying a high voltage (for example, several kV to several tens kV) to the spinning liquid, and the spinning liquid is discharged toward an object by an electrostatic force based on a potential difference between the charged spinning liquid and the object. The spinning liquid discharged by the electrostatic spraying method is sent toward an object in the form of a very fine yarn. The discharged spinning liquid is discharged toward the object after being discharged, and is then attached to the object, and the solvent as a volatile substance is dried, whereby a coating film can be formed on the surface of the object. The coating is a pile comprising fibers.

As shown in fig. 2, the liquid cartridge 10 includes: a liquid storage section 12 capable of storing liquid; a nozzle 14 for ejecting the liquid in the liquid storage portion 12; and a connecting portion 16 connecting the liquid storage portion 12 and the nozzle portion 14.

As shown in fig. 2, the liquid storage portion 12 is a flat bag-shaped sealed container (liquid storage bag) formed by stacking a pair of (two) sheets having the same shape and the same size, and joining outer edges 12a of the two sheets (heat fusion in the present embodiment), and stores liquid therein. Each sheet is composed of a laminate having an inner layer forming an inner surface when formed into a bag shape and an outer layer forming an outer surface. Further, any layer, for example, a barrier layer such as an aluminum foil, an adhesive layer such as a PET film, or the like may be provided between the inner layer and the outer layer.

The inner layer is formed of a material having resistance to the contained liquid and having a sealing effect (hot-melt property). Examples of the material of the inner layer include unstretched polypropylene (CPP), Low Density Polyethylene (LDPE), Linear Low Density Polyethylene (LLDPE), a mixture of LDPE and LLDPE, Medium Density Polyethylene (MDPE), High Density Polyethylene (HDPE), metallocene polyethylene, and ethylene/vinyl acetate copolymer film (EVA). Among them, Low Density Polyethylene (LDPE), Linear Low Density Polyethylene (LLDPE), and a mixture of LDPE and LLDPE are preferable. The outer layer is formed of a material having superior mechanical strength to the inner layer. Examples of the material of the outer layer include polyethylene terephthalate (PET), oriented polypropylene (OPP), and oriented nylon (ONy). Among them, polyethylene terephthalate (PET) is preferable.

As shown in fig. 2 to 4, a region of the liquid storage portion 12 inside the outer edge 12a is a flexible region 12b having flexibility that can be deformed in accordance with a change in volume of the stored content. That is, as shown in fig. 3, the flexible region 12b of the liquid storage portion 12 can be configured to expand as the volume of the stored object increases due to a change in air pressure or a change in temperature, and to contract as the volume of the stored object decreases. Here, "contained substance" is a general term for the liquid contained in the liquid containing portion 12 and the gas (air) sealed inside the liquid containing portion 12.

In the present specification, the expansion state when the flexible region 12b of the liquid storage unit 12 is expanded to the maximum is referred to as the "most expanded state". In the present specification, the apex of the flexible region 12b in the most expanded state is referred to as "most expanded point P", and the linear distance between the most expanded point P of one sheet and the most expanded point P of the other sheet is referred to as "maximum expansion width D". In the case of a bag-like member in which the outer edges 12a of the pair of sheet bodies are joined together as in the liquid storage portion 12 of the present embodiment, a point farthest from the outer edge 12a in the flexible region 12b, that is, a centroid position (center position in a plan view) of the flexible region 12b is usually the most expansive point P. For easy understanding, the shape of the flexible region 12b in the most expanded state shown in fig. 3 is enlarged and does not necessarily conform to the actual shape.

The area of the flexible region 12b (area of the liquid storage part) is appropriately selected according to the size of the liquid storage part 12, and is generally 1500mm²Above 5000mm²The following. The maximum expansion width D of the flexible region 12b is 10mm to 50mm, preferably 15mm to 45mm, and more preferably 20mm to 40 mm. More specifically, the area of the flexible region 12b of the liquid reservoir 12 is about 3300mm²The maximum expanded width D of the flexible region 12b is 30 mm.

As shown in fig. 4, the nozzle portion 14 includes: a flat rectangular base 14 a; a nozzle 14b extending from one face (upper face in fig. 4) of the substrate 14 a; an inflow pipe (not shown) extending from substantially the center of the other surface (lower surface in fig. 4) of the base 14 a; and a pair of engaging pieces 14c extending from the other surface of the base 14 a. The nozzle portion 14 is made of a material having resistance to the liquid contained in the liquid storage portion 12, and is made of, for example, High Density Polyethylene (HDPE), polypropylene (PP), Polyacetal (POM), or the like.

The base 14a has a flow path formed therein for communicating the inflow tube with the nozzle 14b, and a pump (e.g., a gear pump) and a small electrode are disposed in the flow path. The pump is configured to absorb the liquid and circulate the liquid in the flow path by being driven, and the small electrode is configured to electrostatically charge the liquid circulating in the flow path.

The inflow pipe is formed in a cylindrical shape having a structure capable of being fitted into the connection portion 16, and communicates an internal flow passage of the connection portion 16, which will be described later, with a flow passage of the base 14 a. As shown in fig. 4, the nozzle 14b has a discharge hole 15 at the tip, and has a nozzle flow path that communicates the flow path of the base 14a and the discharge hole 15. The pair of engagement pieces 14c are configured to be engageable with an upper end edge portion of the connecting portion 16.

The connecting portion 16 is welded (fused) between a pair of sheets constituting the liquid containing portion 12 such that one end (upper end in fig. 4) is located outside the liquid containing portion 12 and the other end (lower end in fig. 4) is located inside the liquid containing portion 12. The connecting portion 16 is made of a material that is resistant to the liquid contained in the liquid containing portion 12 and is compatible with the inner layer of the liquid containing portion 12, and for example, when the material for the inner layer is CPP or LLDPE, it is made of polypropylene (PP), High Density Polyethylene (HDPE), or the like.

The connecting portion 16 has an inner diameter into which the inflow tube of the nozzle portion 14 can be fitted. As shown in fig. 4, a pair of column portions 16a and an engaging plate portion 16b bridging between the column portions 16a are provided at one end (an end portion located on the outer side of the liquid storage portion 12 (an upper end in fig. 4)) of the connecting portion 16. The engaging plate portion 16b extends outward beyond the two pillar portions 16a, and the pair of engaging pieces 14c of the nozzle portion 14 are configured to be engageable with the extending portions.

The nozzle portion 14 is configured to be attached to the connecting portion 16 by engaging the pair of engaging pieces 14c with the engaging plate portion 16b of the connecting portion 16 in a state where the inflow pipe is inserted into the connecting portion 16. In the state where the nozzle portion 14 is attached to the connecting portion 16, a pair of engaging hole portions 18a having a rectangular shape are formed by the pair of column portions 16a and the engaging plate portions 16b of the connecting portion 16, the pair of engaging pieces 14c of the nozzle portion 14, and the edge portion of the liquid storage portion 12. The connecting portion 16 has a rectangular engaging hole 18b between the pair of engaging holes 18a, which is surrounded by the pair of column portions 16a and engaging plate portions 16b of the connecting portion 16 and the edge of the liquid storage portion 12. That is, the connecting portion 16 has a plurality of (3 in the present embodiment) engaging

hole portions

18a and 18b in a state where the nozzle portion 14 is attached. The engagement holes 18a and 18b are configured such that engagement projections 86, which will be described later, of the storage container 50 can be engaged with each other.

The fiber-forming water-insoluble polymer is a polymer that is soluble with the volatile material and is relatively water-insoluble. In the present specification, the term "water-soluble polymer" means that 0.5g or more of the polymer having been impregnated with 10g of ion-exchanged water after 1g of the polymer has been weighed under an environment of 1 atm 23 ℃ and 24 hours has a property of dissolving in water. On the other hand, the term "water-insoluble polymer" as used herein means that 0.5g or more of the impregnated polymer has insolubility, in other words, the amount of insolubility is less than 0.5g, after the polymer is immersed in 10g of ion-exchanged water after 1g of the polymer is weighed in an environment of 1 atm 23 ℃.

In this case, the measurement conditions were 25 ℃ and the rotor No.43 of the conical plate, the rotation number was appropriately selected depending on the viscosity, and the viscosity of 500 mPaS or more was 5rpm, the viscosity of 150 mPaS or more and less than 500 mPaS was 10rpm, and the viscosity of less than 150 mPaS was 20 rpm.

[ storage Container ]

As shown in fig. 1 and 2, the storage container 50 includes: a container body 60 into which the liquid storage portion 12 of the liquid cartridge 10 can be inserted and removed; and a lid portion 80 provided rotatably to the container main body 60 via the hinge portion 70. The storage container 50 is a resin molded product in which the container body 60, the hinge portion 70, and the lid portion 80 are integrally molded in the present embodiment, but is not limited thereto, and the container body 60, the hinge portion 70, and the lid portion 80 may be manufactured as different parts and assembled.

The container body 60 is formed in a flat bottomed cylindrical shape with one end (upper end portion in fig. 1 and 2) open. Specifically, the container body 60 has a storage space 62 capable of storing at least a part of the liquid storage section 12, and an insertion hole 64 for inserting and removing the liquid storage section 12 into and from the storage space 62. In the present embodiment, the container body 60 has an integral structure formed by resin molding without a seam in the circumferential direction, but is not limited thereto, and may be configured by combining two or more members. As in the present embodiment, there is an advantage that, in the case of an integral structure having no seam in the circumferential direction, even when the liquid storage portion 12 of the liquid cartridge 10 is expanded by the internal pressure, the decomposition does not occur.

The housing space 62 has a size and a shape capable of forming a closed space for housing the liquid storage unit 12 of the liquid cartridge 10 together with the internal space of the cover 80 in the closed state of the cover 80. In the present embodiment, the length of the storage space 62 along the direction in which the liquid storage section 12 is inserted into the storage space 62 (Z direction in fig. 2, hereinafter referred to as "insertion direction Z") is shorter than the length of the liquid storage section 12 along the insertion direction Z. As described above, since the length of the storage space 62 in the insertion direction Z is shorter than the length of the liquid storage portion 12 in the insertion direction Z, the shoulder portion of the liquid storage portion 12 extends to the outside of the storage space 62 in a state where the liquid storage portion 12 of the liquid cartridge 10 is stored in the storage space 62, and therefore, the operability when taking out the liquid cartridge 10 from the container body 60 is improved, and the nozzle portion 14 of the liquid cartridge 10 can be positioned outside the storage space 62. However, the length of the storage space 62 along the insertion direction Z may be longer than the length of the liquid storage unit 12 along the insertion direction Z.

The "insertion direction" refers to a direction in which the liquid storage unit 12 is inserted into the storage space 62, that is, a direction from the insertion hole 64 toward the inside of the storage space 62, and in the present embodiment, refers to a direction from the insertion hole 64 toward the bottom of the container body 60.

The width d of the storage space 62 along the direction in which the liquid storage part 12 is expanded (Y direction in fig. 2, hereinafter referred to as "expansion direction Y") in the direction orthogonal to the insertion direction Z is wider than the width of the liquid storage part 12 along the expansion direction Y in an environment of 1 atm/normal temperature (20 ℃ ± 15 ℃). From the viewpoint of reduction in thickness, the width D of the storage space 62 along the expansion direction Y is preferably smaller than the maximum expansion width D of the liquid storage unit 12 in this environment.

The length of the storage space 62 along the direction orthogonal to the insertion direction Z and the expansion direction Y (X direction in fig. 2, hereinafter referred to as "shoulder width direction X") is longer than the length of the liquid storage unit 12 along the shoulder width direction X.

The housing space 62 is designed such that the length in the insertion direction Z, the width in the expansion direction Y, and the length in the shoulder width direction X are in a relationship of Z ≈ shoulder width direction X > expansion direction Y in the insertion direction. Specifically, the housing space 62 is designed such that the insertion direction Z: shoulder width direction X: the ratio of expansion direction Y is 10: 10: 1, flat space.

The volume of the storage space 62 is appropriately selected according to the size of the liquid storage section 12 of the liquid cartridge 10, but may be set to 8000mm in general²Above 100000mm²Hereinafter, it is preferably set to 20000mm²Above 80000mm²Hereinafter, more preferably 35000mm²Above 65000mm²The following.

As shown in fig. 2, the lid portion 80 has a double-opening type in which a pair of lid bodies (a first lid portion 80a and a second lid portion 80b) are formed. The first lid portion 80a and the second lid portion 80b are coupled to the opening-side end portion of the container body 60 via the hinge portion 70, and are configured to open and close the insertion hole 64 by being rotated about the hinge portion 70. As shown in fig. 1, a finger hooking portion 88 used when opening and closing the lid portion 80 is formed in at least one of the pair of lid bodies (the second lid portion 80b in the illustrated example) so as to protrude in the top surface direction. The finger hooking portion 88 is provided in the second cover 80b in the illustrated example, but is not limited thereto, and may be provided in the first cover 80, or may be provided in both the first cover 80a and the second cover 80 b. The position of the finger hooking portion 88 on the top surface of each lid body is not limited to the illustrated example, and can be any position.

As shown in fig. 2, the first cover portion 80a and the second cover portion 80b each have a semicircular notch portion 82 at a substantially central portion in the shoulder width direction X. A plurality of (3 in the present embodiment) engaging projections 86 that can be inserted into the engaging

holes

18a and 18b of the connection portion 16 of the liquid cartridge 10 are provided to protrude from the cutout portion 82 of the first cover portion 80 a. The engaging projection 86 may be provided in addition to or instead of the notch 82 of the second cover 80 b.

The lid portion 80 is configured such that, in a state where the liquid storage portion 12 is stored in the storage space 62 and the insertion hole 64 is closed by the lid portion 80, the notch portion 82 of the first lid portion 80a and the notch portion 82 of the second lid portion 80b form a through hole 84 through which the connection portion 16 of the liquid cartridge 10 can be inserted (see fig. 1 and 5). The through hole 84 of the lid 80 has an engagement projection 86 that projects toward the connection portion 16 of the liquid cartridge 10 in the same state and engages with the

engagement holes

18a and 18b of the connection portion 16.

As shown in fig. 2, the hinge portion 70 is provided along the shoulder width direction X at the opening side end of the container body 60. The hinge portion 70 is a thin portion formed thinner than the container main body 60 and the lid portion 80, and has flexibility enabling the lid portion 80 to rotate. Further, the thin wall portion does not need to extend along the shoulder width direction X, and may be divided into a plurality of thin wall portions. The hinge portion 70 is not limited to the thin-walled portion, and various configurations such as a configuration in which the container body 60 and the lid portion 80 are coupled to each other via a rotation shaft can be employed.

As shown in fig. 5, the hinge portion 70 is disposed on the upstream side (the lid portion 80 side, the nozzle portion 14 side) in the insertion direction of the liquid storage portion 12 into the storage space 62, with respect to the most expanded point P of the liquid storage portion 12, that is, the centroid position (the center position in plan view) of the flexible region 12b of the liquid storage portion 12, in the state where the liquid storage portion 12 of the liquid cartridge 10 is stored in the storage space 62 of the container body 60. In short, the liquid storage portion 12 of the liquid cartridge 10 is disposed deep so as to cover the most expansive point P with respect to the position of the hinge portion 70 of the storage space 62 of the container body 60. Specifically, the hinge portion 70 is preferably disposed at a position shifted by 25mm from the most expanded point P of the liquid storage portion 12 toward the upstream side (the lid portion 80 side, the nozzle portion 14 side) in the insertion direction of the liquid storage portion 12 with respect to the storage space 62. The hinge portion 70 is preferably disposed at a position shifted from the upper end of the insertion hole 64 toward the downstream side (bottom side of the container body 60) of the liquid storage portion 12 in the insertion direction with respect to the storage space 62 by a distance equal to or greater than the width d of the storage space 62 of the container body 60.

The "upstream side in the insertion direction" refers to the upstream side of the liquid storage portion 12 in the direction of insertion into the storage space 62, that is, the upstream side in the direction from the insertion hole 64 toward the inside of the storage space 62, and in the present embodiment, is referred to as the insertion hole 64 of the container body 60 and the insertion hole 64 in the bottom portion.

The "downstream side in the insertion direction" refers to a downstream side of the liquid containing portion 12 in the direction of insertion into the housing space 62, that is, a downstream side in the direction from the insertion hole 64 toward the inside of the housing space 62, and in the present embodiment, is referred to as a bottom side of the insertion hole 64 and the bottom of the container body 60.

As described above, the hinge portion 70 of the storage container 50 of the liquid cartridge storage container 1 according to the present embodiment is located on the upstream side (the lid portion 80 side, the nozzle portion 14 side) in the insertion direction of the liquid storage portion 12 into the storage space 62 of the container body 60 from the most expanded point P of the liquid storage portion 12 of the liquid cartridge 10.

In the liquid cartridge storage container 1 having such a configuration, as shown in fig. 6(a), even if the volume of the stored substance in the liquid storage section 12 increases due to a change in air pressure or a change in temperature during transportation or storage, even if the liquid storage section 12 expands, pressure (internal pressure) due to expansion of the liquid storage section 12 is not applied to the hinge section 70 and the lid section 80, or even if pressure is applied, the pressure can be suppressed. Therefore, according to the liquid cartridge storage container 1 of the present embodiment, the liquid storage portion 12 of the liquid cartridge 10 can be reliably protected while preventing the lid portion 80 from being accidentally opened, and therefore, breakage of the liquid storage portion 12 of the liquid cartridge 10 can be suppressed.

In particular, in the liquid cartridge storage container 1 of the present embodiment, as described above, since the lid portion 80 is not opened accidentally, the width of the storage space 62 in the expansion direction Y can be made narrower than the maximum expansion width D of the liquid storage portion 12, and thus an extremely small and thin storage container can be realized.

In the thin liquid cartridge container 1, the liquid storage section 12 may expand to the region where the hinge section 70 exists, but even in this case, the pressure applied to the hinge section 70 and the lid section 80 can be dispersed and minimized. That is, when the liquid storage portion 12 expands as the volume of the stored content increases, first, as shown in fig. 6(a), the most expanded point P of the liquid storage portion 12 comes into contact with the inner wall of the container body 60, then, the liquid storage portion 12 expands so that the contact area gradually expands with respect to the inner wall of the container body 60 around the most expanded point P, and finally, as shown in fig. 6(b), expands to the hinge portion 70 and the lid portion 80. Therefore, even if the expanded liquid storage portion 12 comes into contact with the hinge portion 70 and the lid portion 80, the pressure is dispersed over a wide range of the inner wall of the container body 60, and therefore, the hinge portion 70 and the lid portion 80 are difficult to open.

The liquid cartridge storage container 1 of the present embodiment has a through hole 84 through which the connection portion 16 of the liquid cartridge 10 can be inserted in a state where the liquid storage portion 12 is stored in the storage space 62 and the insertion hole 64 is closed by the lid portion 80. According to the liquid cartridge storage container 1 having such a configuration, as shown in fig. 1 and 5, the liquid storage portion 12 of the liquid cartridge 10 can be stored and protected in a state where the nozzle portion 14 of the liquid cartridge 10 is not stored inside but is located outside. In other words, the liquid cartridge storage container 1 of the present embodiment is configured such that, in a state where the liquid storage section 12 is stored in the storage space 62 and the insertion hole 64 is closed by the lid 80, the liquid storage section 12 of the liquid cartridge 10 is stored in a closed space formed by the storage space 62 of the container body 60 and the internal space of the lid 80, and the nozzle section 14 of the liquid cartridge 10 is located outside the closed space. In this way, by configuring not to house the nozzle portion 14 in the closed space but to expose the nozzle portion 14 outside the housing space, it is possible to further reduce the size and thickness.

In the liquid cartridge storage container 1 of the present embodiment, the through hole 84 of the cover 80 is provided with an engagement projection 86 that can be engaged with the

engagement holes

18a and 18b of the connection portion 16 of the liquid cartridge 10. According to the liquid cartridge storage container 1, the liquid cartridge 10 can be prevented from dropping off from the storage container 50 due to vibration, impact, or the like.

In addition, in the cartridge container 1 of the present embodiment, since the lid portion 80 is of a double-opening type including a pair of lid bodies (the first lid portion 80a and the second lid portion 80b), there is an advantage that insertion and removal of the liquid cartridge 10 into and from the liquid containing portion 12 of the container body 60 are easy.

Although the first to third embodiments have been described as preferred embodiments of the present invention, the technical scope of the present invention is not limited to the scope described in the above embodiments. Various modifications and improvements can be added to the above embodiments.

For example, in the above-described embodiment, the engagement projection 86 is provided in the through hole 84 of the cover portion 80, but the present invention is not limited thereto, and the engagement projection 86 may be provided in the connection portion 16 of the liquid cartridge 10. Further, the engaging projection 86 may not be provided at any of the through hole 84 of the lid portion 80 and the connecting portion 16 of the liquid cartridge 10.

In the above-described embodiment, the double-opening type in which the cover 80 is composed of the first cover 80a and the second cover 80b has been described, but the present invention is not limited to this, and a single-opening type in which only one of the first cover 80a and the second cover 80b is rotated may be employed.

In the above-described embodiment, the container body 60 has been described as being formed in a bottomed tubular shape, but the present invention is not limited thereto, and may be formed in a bottomless tubular shape.

The above modifications are included in the scope of the present invention, and are apparent from the description of the scope of the claims.
