Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a container for extruding liquid cosmetics, specifically, a cylindrical container main body, which accommodates a liquefied 111 product inside the tip end and has a piston member for extrusion operation at the rear end side. When the equipped cylinder tBIi is heated to 2 t), the rising air H in the cylinder part due to the pushing operation of the piston member causes the separated product l1l (volume 1115 and cylinder part 123
Li placed on J! 7. There is a push-out container for cosmetics in which the liquid cosmetics on the distal end side are discharged from the distal end by pushing the stopper.

In order to stop the air outflow during the pushing operation of the screw container, a check valve is installed at the inner end of the air supply hole. However, the structure is complicated, and installation and assembly operations during manufacturing are troublesome, and failures are likely to occur.

In view of the above, the present invention has been made to prevent the air from flowing out during the pushing operation of the piston member, without requiring a check valve.
Unpush JRepo II! The hollow part of the piston member, which is attached to a part of the cylinder, is oriented in the axial direction 1;: It! A frontage is formed inside and outside as an air supply port through which the air supply hole can be passed, and the outer end opening is formed so that it can be freely closed with a finger, and the air supply hole can be rI'IMed with the finger at the same time as the piston part is pushed in. There is also a feature that the push-in sweep is released at the same time as when the sweep is released.

Next, embodiments of the present invention will be explained based on the drawings.

(1) is a cylindrical container body with a required length, and a communication hole (2) is opened in the center at a suitable location inside the container body. : I-opening 1 wall (3) is installed, and the tip side of the partition wall (3) is used as a cosmetic storage section (4), and the rear end side is made up of a partition 4 and as a part of the operation cylinder (5). , the container body (1
), that is, the end 1t1 on the side of the cosmetics storage part (4).The nozzle (7), which connects the nozzle hole (6) to the right, is mainly screwed into the screw 411 means. It is installed. The partition wall (3) can be formed integrally with the container body (1), but in the case shown in the figure, it is formed separately from an elastic material such as rubber, and is fitted and fixed inside the container body (1). There is. Liquid cosmetics <a) are stored in the liquefied cosmetics storage section (4), and in the case of the figure, 11 liquefied cosmetics (
a) into a car 1-ridge type cylindrical container (8), and insert the cylindrical container (8) into the curved assembly +1XI container part (4) from the bottom end side. At the same time, the front end H)a') of the cylindrical container (8) is fitted inside the nozzle (7), and the nozzle (7) presses the ICE 'r FIN.
3) Hold the bottom end tightly against the wall.

The 1:1 end portion (8a) between the cylindrical container (8) is
Regarding 7), it is desirable to prevent leakage of the liquefied raw product (a) by combining the parts shown in the figure. 5; Bottom end of the cylindrical container (8) 1. : is provided with a through hole (5)), and a sliding plug (10) is provided on the bottom end side of the cylindrical container (8) to shield between the liquefied crude product (a) and the partition wall (3).
) moves 1-1 in the direction of the axis (iiJ ril: K), and by moving the IFI mover (01) toward the tip side, the liquid cosmetic (a) is transferred to the nozzle hole (6). J, which can be pushed out more, is shaped like a sea urchin.

The first stopper (10) has a circumference tM (1

The present invention is not limited to this, but it is possible to implement various forms that have sealing properties and are slidable, such as forming the entire body in a UX shape from rubber or the like. This saw-1
- Before handling the 5F9 type cylindrical container (8), seal it by pasting aluminum foil etc. on the Jlr 1 opening before loading it into the container body (1). Make sure to peel it off before use. Although it is preferable to store the liquid cosmetics (a) in the container 1 to the container 11L in a rigid manner as described above, it is also preferable to store the liquefied cosmetics directly in the cosmetic storage section (4) of the container body (10). In this case, a movable stopper 121 for shielding the gap between the liquid cosmetic and the partition wall (3) may be provided so as to be inscribed in the inner periphery of the container body (1).

On the other hand, the operation cylinder part 5) has a hollow shaft part (13).

In the figure, (22) is a kit that can be freely attached to the nozzle (7) by screwing or fitting means, and at the center of the inside thereof, it fits into the nozzle hole (6) when it is covered. Is there a protruding frame (23)? ).

・The present invention is illustrated as above, and in order to extrude the liquid cosmetics (a), the container water body (a) is used as shown in Figure 2.
1) Rear end J: Press your finger (24) against the outer end of the shaft (13) of the piston member (15) that can protrude from the rear end (J), passing through the piston member (1!i) to the inside and outside.

Since the air supply hole (19) is closed as shown in L, the air inside the operating cylinder part (5) does not escape to the outside, but is compressed by the pushing operation, and its internal pressure rises. The internal pressure reaches the part of the 18 valve stop (10) in the cosmetic storage section (4) that communicates through the opening of the partition wall (3), and the F! 3 Song 1'# movement (?Hiatus (10) is pushed toward the tip side by the high air pressure of the front chamber L1, and with this movement, liquid cosmetics (a) are pushed out from the nozzle hole 6) at the tip. . , then (if the pushing operation on the piston member (15) is released, the air supply hole (19) will be in the open state and the piston part will advance and return due to the biasing force of the spring (10). 1.
