Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a dispenser that is attached to the mouth of a container and drains the liquid in the container, and in particular, a dispenser that pressurizes the liquid by squeezing the container itself without having a pump mechanism. Concerning a squeeze type dispenser for discharging water.

[Conventional technology]

This type of dispenser includes a cap attached to the mouth of the container and a head rotatably or reciprocably attached to the cap. The head of the dispenser must be configured to allow liquid to flow out and to prevent liquid from flowing out when not in use to ensure a liquid-tight (seal). Therefore, for example, a side hole may be provided at the upper end of the cap, and a rotatable head may be provided with a liquid outflow path that can be aligned with the side hole, and the head may be rotated to align the liquid outflow path with the side hole. There is a known configuration in which liquid can flow out.

Also known is a squeeze-type dispenser in which a valve body is provided at the top of the cap, and a head in which an outflow hole that can be closed by the valve body is formed is attached to the cap in a reciprocating manner.

However, in such a known configuration, the head must be molded separately from the cap.If the head and the cap are integrally molded, the mold cost will be lower, the number of parts will be reduced, and assembly will be easier. We can provide inexpensive dispensers. Therefore, a toggle type dispenser in which the head and the cap are integrally molded is disclosed in U.S. Patent No. 4,124,15.
It is provided as 1.

According to this US patent, the head is integrally molded with the cap from plastic, and a flat spring is formed between the head and the cap via a hinge to connect them. Furthermore, a partially spherical engagement protrusion is formed on the outer surface of the head, and a corresponding partially spherical engagement hole is formed on the inner surface of the cap. The valve body of the head closes the outflow hole at the top of the cap by swinging around the engagement protrusion that is engaged with the retention hole. Also, the head is disengaged and biased by a spring into its oven position so as not to interfere with liquid flow (during use of the dispenser).

[Problem that the invention seeks to solve]

However, in the toggle type dispenser according to U.S. Pat. No. 4,124,151, since the spring is adjacent to the engagement protrusion that is the pivot point, it is difficult to apply a large biasing force to the head by the spring. The tip of the head is located quite far from the pivot point. Therefore, while the dispenser is in use, there is a possibility that the head may swing to a position that prevents the liquid from flowing out. Further, in a configuration in which the cap and the head are disengaged when liquid flows out, it is difficult to use the dispenser as a foamer or sprayer.

[Means for solving problems]

The purpose of the present invention is to provide a toggle type squeeze dispenser that reduces the number of parts, has a head that does not swing to the extent that it prevents the outflow of liquid during use, and can be easily used as a former or spray dispenser. It is said that

In order to achieve this object, according to the present invention, a swingable head is integrally molded with a cap in which a liquid flow path is formed, and by swinging the head, the outlet of the liquid flow path of the cap can be opened and closed. Further, the valve body has a liquid flow path formed therein and is reciprocably attached to the cap so as to be able to close the outflow port of the liquid flow path, and the valve body is attached to the head or the cap so as to be movable in the axial direction of the head. The head includes a connecting member to be connected.

[Effect]

In such a configuration, since the head 2 is integrally molded with the cap, the number of parts is reduced and the dispenser can be provided at low cost. In addition, since the head opens and closes the outflow hole of the liquid flow path while attached to the cap, there is no possibility of the head swinging during use, which will not impede the outflow of the liquid.
Since the valve body can close the outflow port of the liquid outflow path, switching between outflow and non-outflow of the liquid can be easily and quickly performed.

In addition, by incorporating the foaming means and spinner means into the valve body, or by forming them separately but integrally with the cap or head, the dispenser can be used not only as a mere liquid distributor but also as a foamer or sprayer. We can provide dispensers that can.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

As shown in FIG. 1, a dispenser 1 according to the present invention
0 includes a cap 12 that can be attached to the mouth (not shown) of a squeezable container containing a liquid, and a swingable cap integrally molded from plastic via this cap and a hinge 13. It is equipped with a head 14.

A female thread 15 is formed on the inner peripheral surface of the cap 12, and a hollow cylindrical portion 18 extends vertically from the top 16 of the cap 12.
A liquid flow path 18 is formed within the cylindrical portion. Four air flow paths 20 (see FIG. 2) are formed on the inner surface of the lower part of one cylindrical portion. In the configuration in which the air flow path 20 is provided in this manner, the liquid from the suction pipe is mixed with air by attaching the suction pipe 22 to the inner surface of the cylindrical portion below the upper end of the air flow path 20 as shown in Figure 1. , the dispenser can be used as a former. When not used as a former.

The suction pipe is attached to the outer periphery of the cylindrical part. A virgin seal 2 is installed between the outlet of the liquid flow path 20 and the upper end of the suction pipe 22.
3 is integrally molded with the cylindrical portion 18. This virgin seal 23 cuts off communication between the outlet of the liquid flow path 18 and the suction pipe 18 when the dispenser is not in use, thereby preventing inadvertent outflow of liquid when the dispenser is not in use. In the configuration in which the virgin seal 23 is integrally molded with the cap 12 in this manner, the number of parts is reduced and the assembly process is omitted compared to the conventional configuration in which aluminum foil or the like is heat-welded to the cap 12. Furthermore, in a configuration in which aluminum foil, etc. is heat welded to the cap 12, if the aluminum foil, etc. is peeled off, foreign matter is intentionally mixed into the container, and then the aluminum foil, etc. is heat welded again, it is difficult to detect the foreign matter. In the configuration in which the virgin seal 23 is integrally molded with the cap 12, breakage of the virgin seal 23 can be seen at a glance, and contamination with foreign matter can be easily detected. Such a configuration of the present application is particularly effective when storing food or drink in a container, in which a sealing protrusion 24 is formed at the upper end of the cylindrical portion.

This protrusion 24 comes into contact with the inner circumferential surface of the head 14 to ensure liquid tightness between the head and the head 14. In addition, the cylindrical portion 18
Another cylindrical portion 28 extends upwardly from the top 16 of the cap 12 and has a locking portion 30 formed inwardly at the upper end of the cylindrical portion. This cylindrical portion is configured in a shape with four split degrees, as can be clearly seen from FIG.

A pair of corresponding locking portions formed on the head 14 are locked to the locking portions, thereby regulating the raised position or the lowered position of the head 14. Further, a retaining portion 34 is formed inside the upper end of the cap 12, and when the head 14 is swung around the hinge 13, the corresponding engaging portion 3B formed on the head 14 engages with this engaging portion. By being engaged with 34.

Head 14 is engaged with cap 12 .

As can be clearly seen by referring to FIG. 4 in addition to FIG. 1, the head 14 includes a head body 3B that is integrally formed with the cap 12, and an outlet of the liquid flow path 13 that can be closed off via the hinge 13. The valve body 40 includes a valve body 40 and a connecting member 42 that connects the valve body to the head 14 so as to be movable in the axial direction of the head 14. The head main body 38 is formed in a ring shape, and has a corresponding engagement part 3 that is engaged with the engagement part 34 of the head 14.
6 is provided on the outer peripheral surface. In embodiments, the connecting material is
4 spaced apart from each other by 80° and slack in the axial direction of the head 14.
It is made up of strips of books. In addition, the circular flow path 44
is formed at one end of the valve body, and a valve rod 45 is formed at the center of the flow path. The tip of the valve stem 45 has a sharp shape with three ribs so as to easily break the virgin seal 23 formed on the cap 12. On the other hand, an outflow hole 46 is provided at the center of the other end of the valve body 40, and a groove 48 that communicates the flow path with the outflow hole has 12 holes as shown in FIG.
Three pieces are formed spaced apart by 0°.

Channel 44. The outflow hole 48 and the groove 48 constitute an outflow path for the valve body 40 . Further, a pair of locking protrusions 50 and 51 are formed on the outer circumferential surface of the valve body and are spaced apart in the axial direction, and these locking protrusions are locked to the locking portion 30 of the cap 12 and the locking protrusions 50 and 51 are engaged with the locking portion 30 of the cap 12. Regulating the raised or lowered position.

Not only the spatula 14 but also a lid 54 are integrally molded on the cap 12 via a hinge 55, and the lid 54 is located 180'' from the head I4.Lid 5
4 covers the bed 14 engaged with the cap 12,
It is formed into a dome shape so as to be engaged with the cap 12. A grip part 56 is formed on the lid F'54 and extends 180 degrees from the hinge 55, and an engagement protrusion 57 that can be engaged with the hinge 13 is provided on the inner peripheral surface of the grip part 5G.

Cap 12, head 14. In the above configuration in which the lid 54 is integrally molded, the dispenser 10 can be constructed from only two members, that is, the integrally molded cap 12 and the like and the suction pipe. Therefore, an inexpensive dispenser 10 that can be molded at low cost and easily assembled is provided.

The operation of the dispenser 10 having the above configuration will be described in detail below.

As shown in FIG. 1, the cap 12 is integrally molded.
The dispenser IO is assembled by attaching the suction pipe 22 to a predetermined position of the cap 12 among the head 14 and lead 54. Specifically, the dispenser 10 is assembled as follows. First, as shown in FIG. Attach to. Then, the annular channel 44 of the head 14
The valve body 40 of the head 14 is pushed into the cap 12 so that the cylindrical portion 18 of the cap 12 is inserted therein.
is pushed in until the locking projection 51 of the pair of locking projections 50, 51 is locked with the locking portion 30 of the cap 12. At this time, the valve stem 45 is above the virgin seal 23 of the cap 12, and liquid tightness is ensured by the virgin seal. Thereafter, the lid 54 is swung around the hinge 55 until the engagement protrusion 57 is engaged with the hinge 13. By engaging the engagement protrusion 57 with the hinge 13, the lid 54 is attached to the cap 12, covering the head 14. After the head 14 and lid 54 are attached to the cap 12, the suction tube 22 is attached to a predetermined position on the cap 12, and the assembly of the dispenser 10 is completed. Note that the suction pipe 22 may be attached before the head 14 and the like are attached.

The dispenser IO assembled in this manner is attached to the mouth of a container containing liquid, transported, and sold. At this stage, the virgin seal 23 has not been broken, so it remains liquid-tight.

Before use, even if the container is squeezed or tipped over.

The liquid is prevented from flowing out by the virgin seal.

When in use, the virgin seal 23 must first be broken. Therefore, as shown in FIG. The head 14 is exposed by removing the lint 54 from the head 14. The head 14 is then lowered until the virgin seal 23 is broken by the sharp tip of the valve stem 45. With the lid 54 attached to the cap 12, the virgin seal 23 may be broken by applying a pushing force to the lid 54 and pushing down the lid 54 and the head 14 as one unit.In this way, the virgin seal 23 is broken. With the configuration in which the head 14 has a built-in member, there is no need to search for a member to break the virgin seal 23, and the virgin seal 23 can be easily broken. Furthermore, when the virgin seal 23 is broken by pushing down the door 14 alone or together with the lid 54, the valve stem 45 moves along the inner circumferential surface of the cylindrical portion 18, and there is a liquid-tight space between them. is maintained.

Therefore, when the virgin seal 23 is broken, liquid can be prevented from flowing out even if the container is accidentally tilted or squeezed. This double seal structure, which maintains liquid tightness even when the virgin seal 23 is broken, is particularly useful for preventing inadvertent spillage of liquid when the liquid in the container is a chemical such as an insecticide. After breaking the virgin seal 23, the head 14 is pulled up until the locking protrusion 51 locks into the locking portion 30 of the cap 12, as shown in FIG. When the head 14 is in the raised position, the valve stem 45 is in the cylindrical portion 18
The liquid seal between them has been broken. Therefore, if the container is squeezed in this state, for example, the liquid in the container will rise in the suction pipe. The liquid then flows from the suction pipe 22 into the liquid flow path 18 at the upper end of the cylindrical portion.

At this time, the air inside the container is sucked through the air flow path 20, and the liquid is mixed with the air. The liquid flows out from the liquid wave channel 18 of the cylindrical portion 18 and flows through the annular channel 44 formed in the valve body.
．． When the liquid flows into the outflow hole 4G from 11rVi 48, which flows into the outflow hole 4B via the groove 48, as shown in FIG. 3, the liquid collides with the circumferential surface of the outflow hole 4G facing the groove 48.

Due to this collision, the liquid becomes all particles, completely mixes with air, foams, and flows out from the outlet hole as a foam.

In the embodiment, the groove 4B acts as a foaming means, and the dispenser 10 is applied as a foamer. However, if the connecting part between the thin film 48 and the outflow hole 48 is made into a gently curved part to prevent foaming, it can be used as a normal dispenser IO. Also.

So that the liquid from the groove 48 is turned into a vortex at the outflow hole 4B,
If the outlet of the groove 48 is provided in the tangential direction of the outflow hole 4B, 1+
1748 acts as a spinner means and the liquid is swirled out. In other words, the dispenser 10 can be used as a sprayer. Furthermore, as can be seen from the embodiment, by reciprocating the valve stem 45, the liquid can be easily and quickly switched between flowing out and not flowing out.

After use, the dispenser 10 is stored with the lid 54 swung and attached to the cap I2. Even when the valve is not in use, the valve stem 45 is in contact with the inner circumferential surface of the cylindrical portion 1B, as shown in FIG. 6, so that a liquid mass is maintained between them. Therefore, inadvertent leakage of liquid when not in use can be prevented.

In the present invention, it is not essential to integrally mold the lid 54 with the cap 12. When the lid 54 is integrally molded with the cap 12, the lint 54 is attached to the lint 54 to prevent the lid 54 from swinging during liquid outflow. It is preferable that the engaging protrusion 58 is provided with an engaging hole 60 that corresponds to the cap 12 (see FIGS. 1 and 8). Protrusions may be provided respectively, or combinations other than engagement protrusions and engagement holes may be used.

Further, a hinge spring 142 that automatically moves the valve body 40 in a predetermined direction when the neutral point is exceeded may be tapped as shown in FIG. 9 and used as a connecting member. With the configuration in which the hinge spring 142 is used as a connecting member, the raised position and lowered position of the valve body 40 can be easily and quickly set. Also, a diaphragm may be used as a connecting member.

A dispenser 110 according to a second embodiment, the second embodiment of which is shown in FIG. It is different from the first embodiment in that it is formed. In other words, after integral molding, the hinge 13
The head 14 is attached to the cap 12 as shown in FIG. 10 by swinging the engaging part 3B around the engaging part 34 of the cap 12. Valve stem 14
5 is formed into a conical shape with a sharp tip, and for example, four grooves 62 are formed in the conical portion. dispenser 11
0, if the valve body 40 is pressed down sufficiently, the virgin seal 123 is broken by the tip of the valve stem 145. Thereafter, by pulling up the valve body 40 and returning the head 14 to the raised position shown in FIG. 10, the liquid can flow out. That is, if the container is squeezed at this position, the liquid in the container rises in the suction pipe and flows into the liquid purging path 19 of the cylindrical portion I8. At this time, as in the first embodiment, the air inside the container is sucked through the air flow path 20 and mixed with the air. Thereafter, the liquid collides with the conical portion at the tip of the valve stem and flows out from the outlet hole 46 of the valve body 40 via 114B2.

Here, if the opening area of 1.1762 is small, 1 yen'J
When it collides with rt i, it is sufficiently atomized and completely mixed with air. Therefore, the liquid is foamed and the dispenser 110 is used as a foamer. In other words,
If the opening area is small, the conical portion at the tip of the valve stem acts as a foaming means. On the other hand, if the opening area of the groove 62 is large,
Even if it collides with the conical part, it will not become atomized to the extent that it will foam.
It can be used as a normal dispenser 10.

After use, the valve a145 is pushed down until the lower end of the outflow hole 4 is closed with the tip of the valve stem 145 where the Yt82 is not formed. In this way, by blocking the outflow hole 4G with the valve stem i45, inadvertent outflow when not in use is prevented.

In the first embodiment, the valve stem is attached to the valve body 4o of the head 14, and the second valve stem is attached to the valve body 4o of the head 14.
In the embodiment, the valve stem 245 is formed on the cylindrical portion 118 of the cap 12, but may be provided on the lid 254 as shown in FIG. The outflow hole 2 of the valve body is formed in
46 and located above the virgin seal 23. In this state, if the lid 254 is pushed down, the virgin seal can be broken by the tip of the valve body. The lid 254 is then pulled up and swung around the hinge 55 to expose the head 214. When the container is squeezed, the liquid is sufficiently mixed with air and foamed by a foam 66, such as a sponge, disposed in the liquid flow path. It goes without saying that it is used as a normal dispenser lO instead of -.

Note that, as shown in the third embodiment, the valve body 240 may be directly connected to the cap 112 by the connecting member 242, excluding the head body. The material is formed, for example, from a strip of wood or two.

A fourth embodiment is shown in FIG. 13. In a dispenser 310 according to this embodiment, as in the third embodiment, the head main body is removed and the valve body is directly connected to the cap 12 by a connecting member 242. . The other configurations are almost the same as those of the first embodiment, so explanations will be omitted.

A fifth embodiment having another configuration for maintaining liquid tightness when not in use is shown in FIGS. 14 and 15. In this embodiment, the lower end of the valve stem 445 of the dispenser 410 has a cross-shaped cross section, except for a portion 447. A portion 447 of the valve stem is formed into a disk shape. Further, the tip of the valve body 445 is formed into a sharp shape. On the other hand, the liquid flow path 4 formed in the cylindrical portion 418 of the caps 12, 4
18 is formed in a size that ensures liquid tightness between it and a portion 447 of the valve stem. Therefore, in the state 1ffi where the valve body 440 is in the raised position, double sealing is performed in addition to the sealing by the virgin seal 423. If the valve body 440 is pushed down in this state, the virgin seal 423 is broken by the sharp tip of the valve stem 445, as shown in FIG. Since the air flow path 20 extends to just below the virgin seal 423, when the valve body 440 is lowered until the part 447 of the valve stem reaches below the virgin seal, the liquid tightness by the part 447 of the valve stem is also released. Ru. virgin seal 4
23 is broken and the container is squeezed, the liquid in the container flows from the suction pipe 22 into the liquid flow path 418, and when it passes over a portion 447 of the valve stem, it passes through the air flow path 20 and flows into the valve stem 4.
45 and flows out from the outflow hole 446. Thereafter, when the valve body 440 is pulled up and returned to the raised position shown in FIG. 14, the valve stem 447 ensures liquid tightness, thereby preventing inadvertent leakage of liquid when not in use.

In the above embodiments, it was suggested that the dispenser 10 could be applied as a foamer or a sprayer by having the same basic structure and appropriately arranging a foaming means or a spinner means. In other words, by simply selecting some parts with a common basic structure, dispensers,
Since either a former or a spray can be configured, they can be provided at low cost.

However, the head 14 can be pivoted with the cap 12-A.
In the configuration of the present application in which the Y is molded and the ←+ valve body is formed in the cap 12 so as to be able to reciprocate, there is also a configuration in which the foaming means and spinner means are not built into the head assembly or the cap, but are molded separately but integrally. It becomes possible. For example, as shown in Figure 15.
Alternatively, the head H and lid L may be integrally molded with the cap C, and the foaming means F and the spinner means S may be integrally molded with the head H. Further, the foaming means F and the spinner means S,
Furthermore, it may be integrally molded on the cap C instead of the head H.

The foaming means F and the spinner means S may be distributed one by one to the cap C and the spatula H. Here, the foaming means may be a liquid, as disclosed in the first and second embodiments. Either a configuration in which the liquid collides with a wall or a configuration in which the liquid collides with a sponge or mesh may be used. Also, as the spinner means, a configuration in which the liquid flows out in a tangential direction as disclosed in the first embodiment can be used. .

Furthermore, if the foaming means F and spinner means S are not provided and the liquid is allowed to flow out from the outlet of the liquid flow path 20 in the first embodiment, for example, it can be used as a normal dispenser. However, a separate member having a small diameter outlet hole may be integrally molded with either the head or the cap.

〔Effect of the invention〕

As described above, according to the present invention, a head is integrally molded on a cap in which a liquid flow path is formed and a swingable finger, and the outlet of the liquid flow path of the cap is opened and closed by swinging the head. It is possible. Furthermore, a liquid outflow path is formed and a valve body is attached to the cap so as to be reciprocally movable to block the outflow port of the liquid flow path, and the valve body is movable in the axial direction of the head and connected to the head or the cap. The head includes a connecting member.

In such a configuration, the head is integrally molded with the cap, so the number of parts is reduced and the dispenser can be provided at low cost. In addition, since the head opens and closes the outflow hole of the liquid flow path while attached to the cap, there is no possibility of the head swinging during use, which will not impede the outflow of the liquid. Since the outlet of the flow path can be closed, switching between liquid outflow and non-outflow can be easily and quickly performed. In addition, by incorporating the foaming means and spinner means into the valve body, or by forming them separately but integrally with the cap or head, the dispenser can be used not only as a mere liquid distributor but also as a foamer or sprayer. We can provide dispensers that can.
