BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feeding container used for stick-shaped cosmetics such as lipsticks.

[0002]

2. Description of the Related Art As is well known, a feeding container of this type includes an outer cylinder and an inner cylinder which are rotatable relative to each other, and a holder for holding a stick-shaped cosmetic is provided in the inner cylinder so that the holder can be moved up and down. hand,
When the outer cylinder is rotated with respect to the inner cylinder, the holder moves up and down, whereby the stick-shaped cosmetic material is projected and retracted with respect to the inner cylinder.

By the way, some stick-shaped cosmetics have volatility, and an airtight means is provided for such a feeding container for cosmetics (Japanese Utility Model Publication No. 1-11311, Japanese Utility Model Publication No. 1-126464. JP-B, JP-B-1-126565, JP-B-2-36409, etc.).

In the feeding container disclosed in the above publication, the holder is slidable in an airtight manner on the inner surface of the inner cylinder, and a sealing material made of rubber or the like is attached to the inner surface of the cap fitted to the outer cylinder. The sealing material is fitted on the inner cylinder in an airtight manner.

Further, in this feeding container, when the cap is attached to the outer cylinder, the outer cylinder and the cap are relatively unrotatable. This is because when the cap is attached, the outer cylinder and the cap are relatively rotatable,
This is to prevent the inner cylinder from rotating with the rotation of the cap, pushing up the bar-shaped cosmetic material and pressing it against the top plate portion of the outer cylinder to be crushed.

Further, in the feeding container disclosed in Japanese Utility Model Laid-Open No. 1-175717, a sealing material which is fitted to the inner cylinder in an airtight state is loosely fitted to the outer cylinder and attached. With this structure, even when the cap rotates with respect to the outer cylinder,
The rotation of the cap is not transmitted to the inner cylinder to prevent the stick-shaped cosmetic material from being pushed out.
