Description

[Detailed Description of the Invention] The present invention mainly relates to a liquid ejecting container for shampoos and other liquid soaps used for human hair and skin.

Containers for liquid soaps that have been put into practical use in the past are housed in a container body made of flexible synthetic resin, and the container body is held in the hand and pressurized to attach it to the head of the body. The liquid material is injected from the ejecting section. However, when a liquid substance is injected onto the body, it is supplied in one place and then flows through the skin and hair in a linear manner, flowing and falling, so it is difficult to say that it is easy to use, and it is necessary. There is an inconvenience that more than the required amount may be wasted, and to prevent this, it must be quickly spread and applied by hand.

The purpose of the present invention is to solve the above-mentioned inconvenience by turning the liquid into a foam and spouting it out, and even when the remaining amount of the liquid is extremely small, the liquid can be spouted out in the same way as when it was first used. The object of the present invention is to provide a container that has advantages such as ease of operation.

To achieve the above object, the present invention comprises a flexible container body, a flexible air tank housed within the body, and a lid attached to the opening of the body.

The lid body includes an upper member and a lower member, and the upper member is vertically movable and non-removably coupled to the lower member, and has a beak and a cylindrical portion communicating with the lower member. and a valve mechanism for introducing air from the outside.

The upper member is positioned in relation to the lower member such that when pushed down, the communication between the inside of the cylindrical portion of the upper member and the main body is closed, and when pulled up, the communication is opened. ing.

The valve mechanism includes a valve chamber that communicates between the inside of the air tank and the outside, and a valve chamber that closes the communication when the air tank is pressurized via the main body, and closes the communication when the pressurization is released. and a valve member operable to open.

Further, the present invention will be described below based on the embodiments shown in the drawings.

The container of the present invention is composed of a container body 1 and a lid 2.

The main body 1 is made of flexible plastic,
By manually applying pressure to reduce the internal volume, the soap-like liquid L stored inside can be pushed out to the top opening 3. The lid body 2 further includes an upper member 5 having a beak portion 4.
and a lower member 6, and is made of plastic with appropriate hardness. The lower member 6 is provided with a cylindrical portion 7 whose top surface is open at the center, a first chamber 8 whose bottom surface is open at the bottom, and a second chamber 9 which is also open. The lower end of the cylindrical portion 7 has a liquid introduction hole 10 communicating with the first chamber 8 and a conduction hole 11 communicating with the second chamber 9. A liquid guiding groove 12 is provided in the vertical inner surface of the first chamber 8, and a valve chamber 13 whose upper and lower surfaces are open is provided in the upper part of the second chamber 9.
A spherical valve member 14 is housed inside the valve chamber 13, and when the valve member 14 comes into pressure contact with the upper inner surface of the valve chamber, it airtightly closes communication between the valve chamber and the outside, and allows air to flow from the upper inner surface. It is formed so as to establish the communication when separated. The lower member 6 has a skirt portion 15 thereof.
It is attached by screwing a spiral 16 on the inner peripheral surface of the main body 1 to a spiral 17 on the outer peripheral surface of the opening 3 of the main body 1. The upper member 5 includes an outer cylinder portion 18;
An inner cylinder portion 19 is provided. The upper member 5 includes an outer cylindrical portion 18 and a neck portion 20 provided at the upper portion of the lower member 6.
The inner cylindrical portion 19 is fitted into the cylindrical portion 7 of the lower member 6 so as to be vertically movable, and the upper and lower members 5 and 6 are attached to the projections 21a, 21b, 22.
a and 22b, and these prevent the upper member 5 from coming off from the lower member 6. Upper member 5
A capsule-shaped porous member 23 whose bottom surface is open is accommodated in the inner cylinder portion 19 of the holder. Porous member 2
3 is made from ceramics, calcite, plastics, etc. The upper end of a liquid guiding pipe 24 reaching near the bottom of the main body 1 is fitted into the first chamber 8 of the lower member 6, and the second chamber 9 is fitted with a liquid guide tube 24 made of flexible plastic that is housed within the main body 1. Made air tank 25
The upper end of is inserted. In addition, a through hole 2 is provided in the upper part of the upper member 5 to improve air supply to the valve chamber 13.
6 is provided.

When the container of the present invention having the above-mentioned configuration is not in use, the upper member 5, which is a part of the lid body 2, is pushed down as shown in FIG. 3, and when in use, the upper member 5 is pushed down as shown in FIG. However, in the state shown in FIG. 3, the liquid guide hole 10 and the air guide hole 11 are closed at the lower end of the upper member 5, and in the state shown in FIG. The inside of the cylindrical portion 7 of the lower member 6 and the liquid guide pipe 24 are connected to each other, and the liquid guide hole 10
The inside of the cylindrical portion and the inside of the main body 1 are communicated through the liquid guide groove 12 and the inside of the main body 1, respectively. Then, when the main body 1 is held and pressurized by hand in the state shown in FIG. At the same time, the air in the air tank 25 is introduced into the porous member 24 through the air guide hole 11, where the liquid L and air are mixed and form bubbles through the micropores of the porous member 24. The liquid comes out and is ejected from the beak portion 4 of the upper member 5 to the outside. Meanwhile, at the same time, the valve member 14
The air pressure in the air tank 25 presses against the upper inner surface of the valve chamber 13 to close communication between the inside of the second chamber 9 and the outside. When the pressure on the main body 1 due to the grip is released, the main body 1 recovers to its original state due to its own elasticity, but the valve member 14 is separated from the upper inner surface of the valve chamber 13 due to the release of the air pressure and negative pressure, and The two chambers 9 are communicated with the outside, and the outside air is sucked into the main body 1 at once through the air guide hole 11, the liquid guide hole 10, and the liquid guide groove 12, so that the recovery is quickly performed. On the other hand, if the remaining amount of the liquid L in the main body 1 becomes extremely small and cannot be sucked up by the liquid guide pipe 24, if the main body 1 is turned in the opposite direction, the liquid L will be transferred to the liquid guide groove 12. The liquid is guided to the porous member 23 through the air, and is ejected to the outside from the beak 4 in the same manner as described above.

According to the container of the present invention, since it has the above-mentioned configuration and function, the liquid L in the main body 1 can always be used in a foamed state, but the foamed liquid L does not contain air bubbles. Therefore, when it is supplied to the body, it does not flow through the skin or hair, thereby eliminating the above-mentioned inconvenience. In addition, at the same time as the pressure applied to the main body 1 by hand is released, external air is sucked into the main body 1 at once and the main body 1 quickly recovers to its original state, so that the liquid material L can be continuously spouted. It is easy to use and easy to use. In particular, since the air tank 25 is housed in the main body 1, it is possible to supply sufficient air for the foaming process regardless of the amount of liquid L in the main body 1, and to carry out the continuous operation. It can be done more easily.
