BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid pouring device which is mounted on the head of an aerosol container having a nozzle tube projecting a foamed liquid for ejection.

[0002]

2. Description of the Related Art In a certain kind of cosmetics, a liquid is foamed and ejected for use. This kind of liquid cosmetic is stored in an aerosol container, and by pushing inward the nozzle cylinder protruding from the head of the container, the valve function portion provided at the base of the nozzle cylinder is opened, Due to the high pressure in the container, the stored liquid, which is a liquid cosmetic, is ejected in a foamed form from the nozzle cylinder.

The ejection of the stored liquid is at the tip of the nozzle cylinder.
Assemble a pouring body directly to guide the ejection direction of the foamed stored liquid and to make it easier to apply a pressing force to the nozzle cylinder, and push down this pouring body to foam the pouring of the stored liquid. Has been achieved. Then, when the pushing force to the spout is removed, the resilience of the elastic material of the valve function part built into the base of the nozzle cylinder causes the nozzle cylinder to rise back and closes the valve, so the dispensing of the stored liquid is stopped. To do.

[0004]

As described above, in the prior art, the spout is directly assembled to the nozzle cylinder, and the foamed storage liquid ejected from the nozzle cylinder is formed by the spout. Since the liquid is poured out through the pouring path, a part of the foamed storage liquid remains in the pouring path of the pouring body each time the stored liquid is poured out once.

In this way, a part of the stored liquid remaining in the pouring path returns to the liquid state with the passage of time and adheres to the surface of the pouring path. The stored liquid that has adhered to the road surface in the form of liquid will be discharged in the liquid state together with the stored liquid that will be discharged in the form of foam during the next foaming and pouring operation. Not only will it deteriorate, but also the foaming state of the stored liquid will deteriorate, and if the stored liquid adhering to the road surface of the pouring path dries out in a viscous manner, the flow of the foamed stored liquid will deteriorate and smooth foaming will occur. There was a problem that the delivery could not be achieved.

The present invention was devised to solve the above-mentioned problems in the prior art. After the completion of the foaming and pouring operation of the stored liquid, the foamed stored liquid remaining in the pouring path is discharged from the pouring path. It is intended to be removed.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention is directed to a head of an aerosol container (1) having a nozzle tube (3) projecting a stored liquid by being pushed inward ( 2)
A liquid pouring device to be installed in an air chamber (1
6) is formed and is attached to the head (2) of the aerosol container (1), and the suction port (4) made of an elastic material is provided with an assembling port (7) above the nozzle tube (3). And the upper part of the fitting cylinder (26) which is assembled to the head (2) of the aerosol container (1) so as to cover the suction body (4), and the outer periphery of the lower end is inside the assembling port (7). A press-fitting piece (19) integrally formed with a pouring cylinder (18) which is closely fitted and has a communication hole (22) communicating with the air chamber (16) on the inner circumference of the lower end is hinge-coupled. Having a pouring body (17),
The upper part of the pouring body (17) is pushed down by a certain distance against the elasticity of the suction body (4), so that the suction body (4)
Is elastically deformed in the direction of reducing the volume of the air chamber (16), and a communication passage (22) between the inside of the pouring cylinder (18) and the air chamber (16).
Block the communication with the nozzle tube and connect the spout tube (18) to the nozzle tube.
It is characterized in that the nozzle cylinder (3) is pushed down while being communicated with (3).

[0008]

[Operation] When a pressing force is applied to the pressing piece to press the upper part of the pouring body against the elasticity of the suction body, the suction body is elastically deformed in the direction of reducing the volume of the air chamber, and A part of the air is discharged from the communication passage to the outside through the inside of the pouring cylinder. When the pushing down of the upper portion of the pouring body reaches a certain distance, the communication between the inside of the pouring cylinder and the air chamber through the communication passage is blocked, and the nozzle cylinder communicates only with the pouring cylinder. When the nozzle cylinder is pushed inward by further applying a pressing force to the upper part of the pouring body from this state, the valve mechanism built in the base of the nozzle cylinder opens and the stored liquid in the aerosol container foams. It is spouted into a shape and is poured through the pouring tube for use.

When the pushing down force on the upper part of the pouring body is removed, the nozzle cylinder rises and returns to the closed state, and the bubbling and pouring of the stored liquid stops, and the stored liquid in the bubbling state remains in the pouring cylinder. However, the upper part of the pouring body is displaced upward by the elastic restoring force of the suction body that further increases the volume of the air chamber after the upward displacement achieved by the return of the nozzle cylinder is achieved, and the blocking of the communication passage is released. Therefore, the outside air is drawn into the air chamber from the spout cylinder through the communication passage. When the outside air is drawn into the air chamber through the pouring tube, the foamed storage liquid remaining in the pouring tube is drawn into the air chamber together with the sucked outside air.

Since the suction action by the suction body is achieved immediately after the completion of the pouring operation of the stored liquid, a part of the stored liquid remaining in the pouring cylinder is still in a sufficiently foamed state. Since it is extremely susceptible to the influence of the air flow, it is surely and smoothly sucked into the air chamber together with the suctioned outside air.

A part of the stored liquid in the foamed state sucked into the air chamber adheres to the wall surface of the air chamber as it is, and in many cases, it adheres and returns to the liquid state. As the volume of the air chamber decreases, it is not extruded into the pouring cylinder and does not adversely affect the newly stored foamed pouring liquid.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. In the embodiment shown in FIG. 1, the aerosol container 1 stores a storage liquid that is used by foaming, and a head 2 has a nozzle cylinder 3 projectingly provided.

The suction body 4 is made of a soft elastic material such as rubber, and a top portion 6 is integrally connected in a ring shape from the upper end of a cylindrical peripheral wall 5, and a center surrounded by the top portion 6 is formed. There is a built-in mouth 7 in the department.

The suction body 4 is assembled by tightly fitting an assembling cylinder 24 hung from the lower end of the peripheral wall 5 on the peripheral edge of the head 2 of the aerosol container 1, and at the edge of the assembling mouth 7. A fixed cylinder 25 having a large height is provided in the.

The injection body 17 is firmly and stably attached to the aerosol container 1 by tightening the fitting of the assembling cylinder 24 of the suction body 4 to the peripheral portion of the head 2 and bringing the lower end into contact with the aerosol container 1. The push-down piece 19 formed in the shape of a short cylinder having a top is hinged 28 to the upper end of the double-walled fitting tube 26 that achieves and maintains the above-mentioned assembly. The push-down piece 19 is slit between the fitting tube 26 and the upper opening edge except the hinge 28.
27 is formed, and thus, the vertical movement of the hinge 28 as an axis causes the fitting tube 26 to move in and out. Pouring barrel
A skirt cylinder 30 having an inner diameter sufficiently larger than the outer diameter of the nozzle cylinder 3 is extended and hung at the lower end of the nozzle cylinder 3.
The nozzle cylinder 3 is provided on the inner peripheral surface of the boundary between the 18 and the skirt cylinder 30.
An inner collar 31 having an inner diameter equal to that of the nozzle opening is provided around the inner peripheral surface of the skirt cylinder 30, and a vertical groove is formed over the entire height range of the skirt cylinder 30 to form a communication passage 22. There is. The inner collar 31 applies the pressing force from the pouring body 17 to the nozzle tube 3
The lower surface of the push-down piece 19 is flatly inclined so that the lower surface thereof makes surface contact with the upper end surface of the nozzle cylinder 3 as uniformly as possible by swinging and descending about the hinge 28 of the pressing piece 19. It's a face. Further, at a lower surface portion of the push-down piece 19 facing the top portion 6 of the suction body 4, a push-down cylinder 29 having a lower end abutted on the top portion 6 is hung, and when the push-down piece 19 is displaced downward, The volume of the air chamber 16 with respect to the downward displacement of the push-down piece 19 is not limited to the central portion where the fixed cylinder 25 is tightly fitted to the spouting cylinder 18, but the top portion 6 is also deformed by being pushed down by the push-down cylinder 29. The decrease change is increased, so that the suction and discharge capacity of the residual foaming storage liquid in the pouring cylinder 18 is increased.

[0016]

Since the present invention has the above-mentioned structure, it has the following effects.

After the pouring operation, a part of the foamed storage liquid remaining in the pouring cylinder can be surely removed from the pouring cylinder, so that a new storage liquid is generated due to the remaining storage liquid in the pouring cylinder. It is possible to completely eliminate the occurrence of inconveniences such as the poor foaming operation of the foam, the deterioration of the feeling of use due to the residual storage liquid that is poured out together with the foam storage liquid, and the deterioration of the foaming of the storage liquid. It is possible to stably and satisfactorily maintain the foamed pouring of the liquid for a long period of time.

The removal of the residual foamed storage liquid utilizes the up-and-down displacement associated with the pressing operation for pouring the stored liquid foam, so there is no operation for removing the residual foamed storage liquid at all.
By the conventional pouring operation, it is possible to surely eliminate the residual foaming storage liquid for each operation, so that the handling is extremely easy.
