Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a container for dispensing cosmetics in the form of a stick, and in particular, it is possible to cool the container filled with heated molten cosmetics with liquid such as water. This invention relates to a stick-shaped cosmetic dispensing container.

[Conventional technology]

Conventionally, containers for dispensing bar-shaped cosmetics such as lip balm, lipstick, and hair styling products have been opened at both ends.
It has a cylindrical body whose one end surface is a sliding contact surface, an inner plate fitted into the cylindrical body so as to be slidable in the axial direction, and a sliding surface that comes into sliding contact with the one end surface of the cylindrical body. a rotating operating member rotatably engaged with one side of the cylinder, and having an operating shaft protruding from the inner center thereof that is screwed into the inner plate and slides the inner plate in the axial direction; It is known that it is composed of When storing bar-shaped cosmetics in the container, the cosmetics heated to about 80 degrees and liquefied are filled from the inner plate of the cylinder to the upper end of the cylinder, and then the container is closed with air. The cosmetics are solidified by cooling them.

By the way, in the above-mentioned conventional technology, when the cosmetics injected into the cylinder are cooled with air, etc., it takes too much time to solidify the cosmetics, and the air cooling equipment itself becomes large and expensive. It has the disadvantage of becoming. For this reason, a water-cooled type may be considered instead of the air-cooled type described above, but there are the following unresolved problems.

That is, in the above-mentioned prior art stick-shaped cosmetic dispensing container, when the container is cooled with a liquid such as water, the air present in the container is cooled and the inside of the container becomes a negative pressure state, so that the cylindrical body The problem is that cooling water is sucked into the container from between the sliding surface of the rotating operation member and the sliding surface of the rotary operation member, and that the cosmetic material is altered by the cooling water. When the container is placed in the atmosphere after cooling, the air inside the container returns to the normal pressure state, and the cooling water that has entered the container flows out of the container, contaminating the packaging of the container. It is a problem of putting it away etc.

[Problems to be solved by the invention] The present invention was created in view of the problems of the prior art described above.The problems to be solved by the invention are as follows: ,
A bar-shaped cosmetic product that can speed up the cooling process by preventing the cooling liquid from penetrating into the interior even when cooled with liquid such as water. The purpose is to provide a dispensing container.

[Means for solving problems]

The feature of the means adopted by the present invention in order to solve the above-mentioned problems is that a radial step portion that engages with each other is provided on the inner surface of the cylindrical body near one end surface and the outer surface of the inner plate. Each sliding surface of the cylindrical body and the rotating operation member is provided with an annular seal portion that fits closely with each other by engaging the respective step portions.
