Description

[Detailed description of the invention] The present invention relates to a cosmetic container useful for preventing drying and solidification of volatile cosmetics, and includes a container body A equipped with a rotational feeding mechanism and a lid that is detachably fitted onto the container body A. A cap body 1, which is made of a flexible material such as rubber or soft resin and into which the upper part of the container body A is removably inserted, is fixed to a deep part of the lid body B. A series of gaps 2 are formed between the cap body B and the top wall 1' of the cap body 1, and an air hole 3 communicating with the gap part 2 is provided at the bottom of the cap body 1. An exhaust hole 5 is formed in a part of the annular tongue piece 4 that is always in contact with the inner circumferential wall surface of the cap body B, and the outer circumferential surface of the container body 1 is in close contact with the inner circumferential surface of the cap body 1 to create an annular airtight structure. A protrusion 6 is provided, and on the back side of the airtight protrusion 6, an annular airtight valve 7 that rises obliquely toward the outside is provided. The gist of this is a structure that closely resembles the .

The details of the present invention will be explained below with reference to the embodiments shown in the drawings. A is a container body equipped with a rotational feeding mechanism;
B is a lid body that is removably fitted onto the container body A; 1 is installed deep inside the lid body B, and the protrusion 1'' of the top wall 1' is adhesively fixed to the lid body B with an adhesive or the like; The cap body is made of soft synthetic resin and has a series of gaps 2 between it and the lid B from the top wall 1' to the outer peripheral surface.
, an air hole 3 communicating with the gap 2 is formed in the top wall 1', and an annular tongue piece 4 provided at the lower part of the cap body 1 and always in close contact with the inner circumferential wall surface of the lid body B. An exhaust hole 5 is bored in a part of the hole. Reference numeral 6 denotes an airtight protrusion formed on the inner circumferential surface of the cap body 1 in two stages, upper and lower, which comes into close contact with the outer circumferential surface of the outer cylinder A' of the container body A, and moves to maintain airtightness within the container. Reference numeral 7 denotes an annular airtight valve that is integrally molded on the back surface of the upper airtight protrusion 6 and tilts upward toward the outside, and is always separated from the inner circumferential wall surface of the lid body B when the lid is not closed. When the lid B is attached, it is pressed by the container body A and comes into close contact with the inner wall surface of the lid B.
This completely blocks out the intrusion of outside air.

Therefore, as described above, the present invention has a structure consisting of a container body A equipped with a rotating feeding mechanism and a lid body B that is detachably fitted onto the container body A, and is made of a flexible material such as rubber or soft resin. The cap body 1, into which the upper part of the container body A is removably fitted, is fixed to the deep part of the cap body B, and a series of gaps are formed between the cap body 1 and the lid B from the top to the outer peripheral surface of the cap body 1. 2, an air hole 3 communicating with the gap 2 in the top wall 1' of the cap body 1, and an annular tongue piece provided at the bottom of the cap body 1 and always in contact with the inner circumferential wall surface of the lid body B. An exhaust hole 5 is bored in a part of the cap body 1, and an annular airtight protrusion 6 is provided on the inner circumferential surface of the cap body 1 so that the outer circumferential surface of the container body A comes into close contact with the outer circumferential surface of the container body A. An annular airtight valve 7 is provided which is inclined upward toward the side, and this airtight valve 7 comes into close contact with the inner circumferential wall surface of the lid B by pressure from the container body A. When the container body A enters the cap body 1 when the container body A enters the cap body 1, the air inside the cap body 1 is discharged from the air hole 3 through the gap 2 to the outside from the exhaust hole 5. There is no pressure resistance, and the lid B can be attached very smoothly. When the lid B is attached, the outer cylinder A' of the container body comes into pressure contact with the airtight protrusion 6 of the cap body 1, and due to the pressure of the container body A. The airtight valve 7 comes into close contact with the inner wall surface of the lid B, and the airtight protrusion 6 and the airtight valve 7 completely block air from entering the container, ensuring airtightness inside the container, and preventing volatile makeup from entering the container. This makes it possible to obtain a cosmetic container that is extremely useful in preventing drying and solidification of ingredients.
