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 discharging an appropriate amount of the cosmetic.

[Prior Art] Conventionally, this type of cosmetic storage container has a main body provided with a partition plate that can be slid back and forth, an inlet opening formed in the upper surface of the main body, and a valve installed in the inlet opening. A cosmetic storage container is known in which an elastic acting body is placed over the body, and the cosmetic stored in the main body is oozed out through a pressure chamber within the acting body by the pressure of the acting body. (Utility Model Application No. 61-122711).

[Problems to be solved by the invention] In the container shown in Utility Model Application Publication No. 61-122711, cosmetics, especially paste cosmetics, are filled during the filling process. The inclusion of air bubbles was more or less unavoidable.
Air bubbles mixed into the main body can be removed during use of the container.
They often coalesce, and if it occurs at the bottom of the valve body, the mechanism will not work properly even if you press the effecting body,
A phenomenon occurred in which the ejection effect could not be obtained. In this way, if a large bubble forms at the bottom of the valve body,
There was a drawback that the discharge action stopped.

[Means for solving the problems] The present invention has been improved to eliminate the above-mentioned drawbacks, and includes a partition plate that can slide back and forth within the main body.
A suction opening is formed in the upper surface of the main body, an elastic acting body is placed over the suction opening via a valve body, and the cosmetic stored in the main body is drawn out by the pressure of the acting body. In the cosmetic storage container that exudes water through a pressure chamber in the working body, a filling opening is formed in a part of the peripheral wall of the main body, and a plug body has a flat groove that communicates the inside of the main body with the pressure chamber. The cosmetic storage container is characterized in that the filling opening is closed.

[Function] As described above, the present invention creates a cosmetic storage chamber directly under the valve body located above the suction opening by providing a plug body having a flat groove that communicates between the inside of the main body and the inside of the pressure chamber. The cosmetic storage chamber is now arranged via a flat groove. In this way, the generation of large bubbles at the bottom of the valve body could be prevented. In addition, even if large air bubbles occur in the cosmetic storage area near the flat groove, the air bubbles will be gradually discharged by the valve body through the flat groove, and the discharge action will not stop. .

[Example] The structure of the present invention will be explained below based on the drawings showing the example.

Reference numeral 1 denotes a rectangular cylindrical main body for storing a liquid or paste cosmetic 2. A filling opening 3 is bored in a part of the peripheral wall of the main body 1, and a recess 5 is formed in the upper surface 4 of the main body 1. A dish portion 6 is formed, and a suction opening 7 is bored in the center of the recess 5 .

On the other hand, 10 is a ring body, which is adhered to the recess 5. Reference numeral 11 denotes an elastic effecting body, which forms a pressing piece 13 with a pressure chamber 12 inside thereof, and a valve piece 14 that elastically contacts the upper surface 4 is integrally provided in the shape of an outer flange. The effecting body 11 is fitted into the ring body 10 and fixed to the main body 1, but a valve body 15 is provided in advance, which closes when the internal pressure of the effecting body 11 increases, and opens due to negative pressure. Discharge path 1 as a leak path between the outside and the outside
Form 6.

Incidentally, after the cosmetic 2 is filled through the filling opening 3, the filling opening 3 is closed by fitting the stopper 8. The plug body 8 is formed with a flat groove 9,
The inside of the pressure chamber and the inside of the main body 1 are communicated through the flat groove 9. In the drawing, the flat groove 9 is formed on the surface of the stopper 8, but it may be formed inside the stopper 8. In the drawings, flat grooves 9 are formed around the four sides in order to prevent the plug 8 from having any directionality when it is fitted and fixed into the filling port 3.

Further, in the main body 1, a partition plate 18 that is in close contact with the inner wall 17 of the main body 1 is provided upright against the bottom wall 19,
It is divided into two compartments: a cosmetic storage compartment 20 and an air compartment 21. The partition plate 18 is configured to be able to slide back and forth within the main body 1 while maintaining close contact with the inner wall 17. position. The shape of the partition plate 18 is a plate-shaped body formed so as to be in close contact with the inner wall 17, and there is no particular limitation on its thickness, but it will be stable if it is formed thicker. It is effective as a means for smooth sliding. Further, as shown in the figure, only the portion that is in close contact with the inner wall 17 may be formed to be thick.

Further, a side lid 22 may be sealed on the air chamber 21 side of the main body 1 by a method such as fitting, ultrasonic welding, adhesion, etc. in order to prevent the partition plate 18 from falling off. At this time, in order to prevent changes in internal pressure due to increases and decreases in the volume of the air chamber 21 due to the sliding of the partition plate 18 and to maintain a constant constant equal to the external pressure, a vent hole 23 for air venting is provided in a part of the air chamber 21 side. It is recommended to set it in

Furthermore, at the beginning of using the cosmetic storage container of the present invention, in order to make the discharge of the cosmetic 2 smoother, the extrusion portion 24 that can press the partition plate 18 against the side lid 22 is provided with a spring. 25 may be provided. The push-out portion 24 has operation protrusions 33 on the left and right sides, and is attached to the side lid body 22 by being fitted into a fitting groove 34 . The left and right operation protrusions 33 are not only attached to the side lid body 22 but also attached to the partition plate 1.
It also performs the pressing action of 8. When the partition plate 18 is pressed and slid by the action of the pushing part 24, the cosmetic 2 passes through the suction opening 7 and the valve body 15 and enters the pressure chamber 12, so that the subsequent pressing of the pressing piece 13 This allows the cosmetics 2 to be smoothly discharged into the dish portion 6.

The cosmetics storage container molded with the above structure can be used alone as is, but the containers shown in FIGS.
As shown in the figure, the storage section 26 in the compact container
Furthermore, it is also possible to use it by storing it together with the applicator 27 such as a sponge or puff, which is a particularly effective means in practice. In addition, when storing the cosmetic storage container in a compact container, on the cosmetic storage container side, a locking protrusion 28 is formed on the lower edge of the filling opening 3 of the main body 1, and a locking protrusion 28 is formed on the lower edge of the extrusion portion 24. A locking protrusion 29 is formed on the side of the compact container, and a locking groove 30 in which the locking protrusion 28 locks is formed on the side wall of the storage portion 26 on the side of the compact container, and a locking groove 30 is formed on the side wall of the storage portion 26, and the locking protrusion 29 is formed on the opposite side.
By forming a locking groove 31 in which the holder is locked and an engaging groove 32 in which the extruded portion 24 is engaged, storage can be achieved without the need for adhesive or the like. In this case, the action of the spring 25 allows the cosmetic storage container to be attached to and removed from the compact container with a single touch, which is convenient.

[Effects of the invention] As detailed above, the present invention provides a stopper having a flat groove that communicates between the inside of the main body and the inside of the pressure chamber, and inhales the cosmetics stored in the main body through the flat groove. Since it is configured to communicate into the pressure chamber through the opening and the valve body, air bubbles that get mixed in during the filling process, etc.
Since it can be effectively discharged from the main body, the disadvantage of stopping the discharge action has been eliminated.

Therefore, although the present invention is a container for storing liquid or paste-like cosmetics, it does not stop discharging the cosmetics simply by the pressing action of the acting body.
Moreover, the discharge can be performed simply and quickly.

In addition, it is possible to store it together with the application body in a compact container, which is extremely portable and convenient.
