Description

[Detailed description of the invention] [Industrial application field] The invention is applicable to liquids such as emulsions and foundations,
Or, as well as storing paste cosmetics,
The present invention relates to a cosmetic storage container capable of exuding an appropriate amount of the cosmetic.

[Prior Art] Conventionally, liquid or paste cosmetics have been stored in containers such as bottles and tubes depending on the intended use of the product.

These containers usually have a cap that is screwed together, and after opening the cap and applying an appropriate amount of cosmetics to an applicator such as a sponge or puff. To operate it, the cosmetics were taken out by shaking the bottle or pressing the body of the tube.

In addition, a through hole is made in the top wall of a cylindrical container with a movable bottom wall that is inserted into the cylinder, as seen in Utility Model No. 59-153875, and a handle rod with a notch at the bottom and an elastic cap are installed. A container for dispensing cream or the like has also been devised, which has a push button integrated with the body, and the handle of the push button is vertically freely inserted into the through hole.

[Problems to be solved by the invention] However, conventional containers such as bottles and tubes are difficult to accommodate and bulky when carried in handbags, cosmetic pouches, etc.
The shape was extremely inconvenient for use.

In addition, the operation of taking the cosmetics out of the container into the applicator is not only very cumbersome, but it is often difficult to extract the appropriate amount of cosmetics, which is inconvenient and results in disadvantages for consumers. It also had

Furthermore, there was also a hygienic problem in that various bacteria could enter the cosmetics during use or storage, causing the cosmetics to deteriorate in quality.

On the other hand, in the case of the pouring container for cream etc. seen in Utility Model Publication No. 59-153875, it is extremely difficult to maintain a constant tight insertion force between the handle rod and the through hole when processing the handle rod and the through hole. be. Therefore, if the tight insertion force is weak, the sealing between the handle rod and the through hole will be reduced, which may cause backflow or weaken the suction effect.On the other hand, if the tight insertion force is strong, the handle will close inside the communication hole. The rod does not move up and down smoothly, making pressing the push button very cumbersome and making it difficult for the elastic cap body to return elastically.

In addition, when pressing the elastic cap, the contents are not necessarily poured out only into the saucer, but due to the structure, there is a possibility that the contents may ooze out in all directions from the periphery of the elastic cap.

[Means for Solving the Problems] The present invention has been improved in order to eliminate the above-mentioned drawbacks. a pressure piece serving as a chamber;
and an elastic effecting body integrally provided with a valve piece that elastically fits on the upper surface and covered in the recess, and an actuator positioned above the suction opening in the recess to increase the internal pressure of the effector. a valve body that closes by and opens by negative pressure;
The device is characterized by comprising a discharge passage formed between the pressure chamber and the outside, and a partition plate that closely partitions the inside of the main body into two chambers and can slide back and forth.

[Embodiment] The structure of the present invention will be described below with reference to drawings showing one embodiment of the invention. As shown in FIG. In the main body, a filling port 3 is formed in a part of the peripheral wall of the main body 1, and after filling the cosmetic 2 through the filling port 3, the plug body 4 is fitted and fixed to close the filling port 3. Obstruction. Next, a recess 6 and a plate 7 are formed on the upper surface 5 of the main body 1, and a pressing piece 9 having a pressure chamber 8 inside, and a valve piece 1 elastically fitted to the upper surface 5 are provided.
0 is integrally provided in the shape of an outer flange.
A valve element 13 is provided in advance on the suction opening 12 in the recess 6, which closes when the internal pressure of the operating body 11 increases and opens when negative pressure is applied to the pressure chamber 8. A discharge passage 14 as a leak passage is provided between the inside and the outside.

Furthermore, as shown in FIG.
7, and has a cosmetic storage chamber 18 and an air chamber 1.
The partition plate 16 maintains a close contact with the inner wall 15, and the front end wall 20 on the side of the suction opening 12 in the main body 1 and the front end wall 2.
0 and the rear end 21 facing each other, and is positioned under the suction opening 12 before being filled with the cosmetic 2. The shape of the partition plate 16 is a plate-shaped body formed so as to be in close contact with the inner wall 15, and its thickness is not particularly limited, but if it is molded thicker, the partition plate 16 will become thicker. Since it is difficult to tilt within the main body 1, it is effective as a means for smoothly sliding the partition plate 16.

Further, in order to prevent the partition plate 16 from falling off, the side lid 22 may be sealed to the rear end wall 21 by fitting, ultrasonic welding, adhesion, or the like. At that time, the air chamber 19 due to the sliding of the partition plate 16
In order to prevent changes in the internal pressure due to increases and decreases in volume and to keep it constant and equal to the external pressure, it is necessary to make a small hole 23 in a part of the side lid 22 for venting air.

Cosmetic storage container 24 formed with the above configuration
can be used alone as is, but as shown in FIG.
It is also possible to use it together with the applicator 27 such as a sponge or puff, which is particularly advantageous in practical terms. Note that 28 is a lid of the compact container 25.

[Function] Since the present invention is constructed as described above, when using the present invention in the example shown in FIG.
The application body 27 lightly presses the pressing piece 9 on the effecting body 11 of the cosmetic storage container 24. The valve body 13 pressed by the pressing piece 9 seals the suction opening 12 and increases the internal pressure of the pressure chamber 8 . When the pressing force is released after increasing the internal pressure, as the pressing piece 9 restores its current shape, the internal pressure in the pressure chamber 8 gradually decreases to negative pressure, so that the valve body 13 The cosmetic 2 is then opened into the recess 6 through the suction opening 12.
and into the pressure chamber 8. By repeating the above operation again, the cosmetic 2 is guided to the discharge path 14. Valve piece 1 that comes into elastic contact with the upper surface 5
0 and spreads to the exuding plate part 7.
Therefore, after rubbing off the extruded cosmetic 2 with the applicator 27, the makeup operation can be started immediately.

By repeating the extrusion operation, the amount of cosmetics 2 remaining in the cosmetics storage chamber 18 gradually decreases, so that the partition plate 16 slides toward the front end wall 20. On the other hand, the air chamber 19 will expand and become depressurized if left as it is, so by replenishing the outside air through the small holes 23 formed in the side lid 22 at the rear end 21, the air chamber 19 can be maintained at a constant state equal to the outside pressure. I'm keeping it.

[Effects of the invention] As detailed above, although the present invention is a container for storing liquid or paste cosmetics, it is extremely easy to use by simply pressing the pressing piece 9 lightly with the applicator 27 or the like. This is very convenient because it allows the cosmetic 2 to ooze out. Moreover, the extrusion operation is smooth, and it is easy to take out only the appropriate amount for one use, and the seal can be maintained without contacting the outside air until it oozes into the dish part 7, so there is no waste and hygiene. It is possible to use
It also has the advantage that consumers can use it with great peace of mind. Furthermore, it is also possible to accommodate the application body 27 and the like in the compact container 25, which is extremely portable and convenient.

However, since the present invention has many excellent advantages and is simple in structure and easy to mold, it is possible to provide a large quantity of convenient and inexpensive products to consumers.
