[Conventional technology]

There are various types of liquid cosmetic products, and they are stored in a prescribed bottle or the like depending on their intended use.

[Problem that the invention attempts to solve]

However, this type of bottle is bulky, making it extremely unsuitable as a portable item, and there is also a high risk that bacteria may enter the cosmetic during use or storage, causing the cosmetic to deteriorate in quality.

In particular, when absorbent cotton or sponges are soaked with cosmetics, it is difficult to effectively apply the cosmetics to these cosmetic tools, resulting in a lot of waste, and there are disadvantages in that they are difficult to operate.

[Structure of the idea]

[Means for Solving the Problems] The present invention relates to a liquid cosmetic storage container devised to solve the above-mentioned conventional inconveniences, and includes a case body for storing liquid cosmetics, and a case body. It has a bottomed cylinder that hangs down from the top wall of the cylinder, and a pressure piece made of an elastic material that is airtightly assembled on the upper surface of the top wall and has a pressure chamber inside, and there is a discharge passage between the pressure chamber and the bottomed cylinder. , suction passages are formed between the pressure chamber and the inside of the case, and check valves are provided at the upper end of the bottomed cylinder and at the opening end of the suction passage on the pressure chamber side.

[Function and Examples]

An embodiment of the present invention will be described below with reference to the drawings.

First, reference numeral 1 in the figure is a compact container, which has a structure in which a thin box-shaped main body 2 and a lid 3 with a mirror plate arranged on the inner surface are assembled via a hinge 4 so as to be openable and closable. The storage container 5 of the invention is assembled.

The storage container 5 has a structure in which a bottomed cylinder 15, a pressing piece 24, etc. are assembled to a case body 6, and the case body 6 is composed of an upper case 7 and a membrane body 10.

The upper case 7 is a short cylindrical body having a cylindrical wall 9 hanging from the outer periphery of the top wall 8, and the lower end opening is sealed via a membrane 10 made of a soft material to form the case body 6.
A desired liquid or creamy cosmetic with relatively low viscosity is stored inside.

In the illustrated embodiment, a lower case 11 is assembled to the lower end of the case body 6.
is a short cylindrical body with a bottom corresponding to the upper case 7, and is constructed by erecting a peripheral wall 13 on the outer periphery of the bottom wall 12, and has a ventilation hole 14 formed in a part of the bottom wall 12, and is connected to the upper case 7. The cylindrical wall 9 of the lower case 11 is tightly fitted into the peripheral wall 13 of the lower case 11. During this assembly, the membrane body is formed between the bottom wall 12 of the lower case 11 and the lower end of the cylindrical wall 9 of the upper case 7. By pinching the peripheral edge of the case body 6, the sealing of the case body 6 is ensured firmly.

Next, regarding the upper case body 7, its top wall 8
A bottomed cylinder 15 is integrally suspended from a part of the wall, and an assembly pin 17 of a predetermined length is erected at the bottom 16 of the bottomed cylinder 15. Hole 1
8 is opened, and a plurality of holding pieces 19 are provided to protrude inward around the upper end opening.

Further, another part of the top wall 8 (a corner in the illustrated example) is a thick part 20, and a circular assembly groove 21 is provided on the upper surface of this thick part 20. 2
A discharge hole 22 and a suction hole 23 are vertically penetrated through the thick part 20 surrounded by 1.

A pressing piece 24 is attached to the upper surface of the thick part 20 of the top wall 8, and this pressing piece 24 is formed of an elastic material in the shape of a hemispherical shell, and its lower end periphery is attached via a ring packing 25. is tightly fitted into the assembly groove 21 to form a pressure chamber 26 within the pressing piece 24.

A discharge passage 27 is formed between the pressure chamber 26 and the bottomed cylinder 15, and a suction passage 29 is formed between the pressure chamber 26 and the inside of the case body 6.

In the illustrated embodiment, the discharge passage 27 is formed by a pipe 28, one end of which is tightly assembled into the assembly hole 18 of the bottomed cylinder 15, and the other end is inserted into the discharge hole 22 in the thick portion 20. The suction passage 29 is formed by the suction hole 23 in the thick wall portion 20.

By the way, the bottomed cylinder 1 which is the open end of the discharge passage 27
A first check valve 30 that opens when the internal pressure of the pressure chamber 26 increases and closes when negative pressure is provided is provided at the upper end of the pressure chamber 5 (see FIG. 4).

This first check valve 30 has a configuration in which an assembly tube 32 is suspended from the center of the lower surface of a disc-shaped valve piece 31 having a diameter sufficiently larger than the diameter of the open end of the bottomed tube 15. It is molded from a soft material such as rubber, and the assembly cylinder 32 is firmly fitted and fixed to the assembly pin 17 in the bottomed cylinder 15, and the open end of the bottomed cylinder 15 is sealed with the valve piece 31.

Further, a second check valve 33 is provided at the open end of the suction passage 29 on the pressure chamber 26 side (see FIG. 5).

In the illustrated embodiment, this second check valve 33 is
3 and seals the suction hole 23.
The pressure chamber 26 opens due to negative pressure.

Now, in the above-described configuration, both the first and second check valves 30 and 33 are normally in the closed position.

In this posture, when the hemispherical shell-shaped pressing piece 24 protruding from a part of the top wall 8 of the case body 6 is pressed, the pressing piece 24 is elastically deformed and the internal pressure increases. The stop valve 33 is strengthened in its closed position by receiving pressure, and this pressure is transmitted from the discharge hole 22 to the assembly hole 18 through the pipe 28 serving as the discharge passage 27.
The valve reaches the bottomed cylinder 15 and pushes up the valve piece 31 of the first check valve 30 to open it.

Then, when the pressing force on the pressing piece 24 is released, the pressing piece 24 elastically returns to a hemispherical shell shape, but at this time, the inside of the pressing piece 24 becomes in a negative pressure state. Therefore, the first check valve 30 of the bottomed cylinder 15, which communicates with the pressure chamber 26 via the discharge path 27, is closed.
At the same time, the second check valve 33 of the suction hole 23 opens due to the negative pressure in the pressure chamber 26 .

As a result of opening the second check valve 33, the suction passage 29 opens, so that the liquid cosmetic in the case body 6 flows into the pressure chamber 26 and is stored therein, and a portion of it flows into the discharge passage 27. and reaches into the bottomed cylinder 15. Therefore, by pressing and deforming the pressing piece 24 again, the cosmetic stored in the pressure chamber 26 etc. is poured out from the opened first check valve 30 onto the upper surface of the top wall 8, so that it can be used. It is.

Note that due to the negative pressure in the pressure chamber 26, the first check valve 3
0 closes, but at this time the valve piece 31 deforms too much and is sucked into the bottomed cylinder 15.
To prevent the first check valve 30 from opening again, a holding piece 19 is provided protruding from the upper end of the bottomed cylinder 15 to support the valve piece 31 from below.

Also, by repeating the above operation, the case body 6
When the cosmetics inside the case body 6 are sucked into the pressure chamber 26, the inside of the case body 6 also becomes negative pressure, so it is assumed that the elastic return of the pressing piece 24 may not be performed smoothly, and therefore the cosmetics inside the case body 6 The membrane body 10 is arranged so that the volume inside the case body 6 becomes smaller as the water flows out. That is, due to the above phenomenon, the membrane body 10 gradually deforms, and the case body 6 itself becomes deflated (as shown by the imaginary line in FIG. 3).
In order to ensure the deformation of this membrane body 10, the lower case 11
A ventilation hole 14 is formed in the lower case 11 to prevent the space between the lower case 11 and the membrane body 10 from becoming airtight.

[Effect of the invention]

As is clear from the above description, the liquid cosmetic storage container 5 of the present invention is a case that is fitted into a compact container 1 consisting of a main body 2 and a lid 3, and that seals and stores cosmetics. Body 6 and bottomed tube 1
5 and a pressing piece 24, a discharge passage 27 is formed between a pressure chamber 26 formed in the pressing piece 24 and the bottomed cylinder 15, and a discharge passage 27 is formed between the pressure chamber 26 and the case body 6.
A suction passage 29 is formed between the bottomed cylinder 15 and the bottomed cylinder 15.
A first check valve 30 is provided at the open end of the pressure chamber 26 that opens when the internal pressure of the pressure chamber 26 increases and closes when the internal pressure of the pressure chamber 26 increases. A second check valve 33 that opens when pressure is applied is provided, and by pressing the pressure piece 24, an appropriate amount of the cosmetics in the case body 6 can be poured out from the upper end of the bottomed cylinder 15 without coming into contact with the outside air. Furthermore, since the membrane 10 of the case body 6 is deformed and its volume is reduced by pouring out the cosmetic, a smooth pouring operation can be achieved.

In addition, since the cosmetic is poured out so as to seep into the upper surface of the top wall 8, the cosmetic can be easily soaked in using a cosmetic tool such as a sponge near the first check valve 30. It becomes easy to use.

Therefore, according to the present invention, although it is a container for storing cosmetics such as liquids and creams with low viscosity, it can be assembled into a compact container, making it extremely convenient to carry, easy to pour, and easy to handle. It is easy to pour out only the desired amount to be used, and the seal can be maintained without contacting the outside air until it is poured, so it is hygienic and waste-free, and the structure is simple and easy to mold. , the present invention has many excellent effects.
