DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stick-shaped cosmetic dispensing container, and more particularly, to a container having a projection formed on the outer periphery of a receiving tray filled with a stick-like cosmetic and having a vertical groove outside the receiving tray. The present invention relates to a rod-shaped cosmetic dispensing container in which a main body and an inner cylindrical body having a spiral groove are provided outside the container main body, and a projection penetrates the vertical groove and is rotatably fitted into the spiral groove. It is.

[0002]

2. Description of the Related Art Conventionally, this type of stick-shaped cosmetic dispensing container is constituted by a container body having a vertical groove, an inner cylinder having a spiral groove, a tray filled with a rod-shaped cosmetic, and the like. Various problems occur when the parts are deformed during molding or have dimensional variations.

For example, when the inner diameter of the inner cylinder is formed larger than the outer diameter of the container body by a specified amount or more, the gap between the inner cylinder and the container body becomes large, and the frictional resistance during rotation decreases. If the container is carried in this state, the container is idled due to the vibration, whereby the tray filled with the cosmetic rises, and the tip of the cosmetic may hit the inner top surface of the cap and be crushed.

If the inner diameter of the inner cylinder is smaller than the outer diameter of the container body by a specified amount or more, the fitting force between the inner cylinder and the container body becomes too large, and the frictional resistance during rotation increases. There is also a problem that the usability is significantly deteriorated.

[0005] In order to solve such a problem, a conventional example incorporates an elastic member such as an O-ring between the container body and the inner cylindrical body to absorb variations in dimensions, and thereby, when the inner cylindrical body is rotated during rotation. It is adjusted so that a suitable frictional resistance is obtained between the container and the container body.

In the container disclosed in Japanese Utility Model Laid-Open Publication No. 3-123422, a plurality of vertically long elastic projections are erected on the outer periphery of the lower part of the container body, and these elastic projections are pressed against the inner peripheral wall at the lower part of the inner cylinder. Thus, during rotation, an adjustment is made such that an appropriate frictional resistance is obtained between the inner cylinder and the container body.

[0007]

However, in such a conventional container, since an elastic member such as an O-ring is a separate component, there is a problem that the production cost is increased and the assembling work is complicated. . In addition, there is a problem in durability of an elastic member such as an O-ring.

In the container disclosed in Japanese Utility Model Application Laid-Open No. 3-123422, an elastic member is integrally erected on the container body, but this elastic protrusion is made to correspond to the dimensional variation between components. In order to obtain an appropriate rotational friction resistance between the inner cylinder and the container body during rotation, the length and thickness of the projection itself must be adjusted to provide flexibility.

In order to make the elastic projections more flexible, it is necessary to lengthen the projections in the vertical direction, which requires a space in the container in the length direction. For this reason, the entire container becomes long, and there are restrictions on the design. In addition, when the thickness of the elastic projection is also reduced, there is a problem that during repeated rotation, elastic fatigue is likely to occur, and it becomes difficult to obtain an appropriate frictional resistance.

The present invention has been made in view of such a conventional problem, and an object thereof is to provide an appropriate frictional resistance when the inner cylinder and the container body rotate, without impairing the appearance, and An object of the present invention is to provide a stick-shaped cosmetic dispensing container in which the performance of an elastic member is less deteriorated.

According to the present invention, there is provided a container body and a container having a projection formed on an outer periphery of a tray filled with a bar-shaped cosmetic material and having a vertical groove outside the tray. An inner cylindrical body having a spiral groove is provided on the outside of the main body, and a rod-shaped cosmetic dispensing container in which a protrusion penetrates the vertical groove and is rotatably fitted into the spiral groove, wherein The lower peripheral wall extends in the circumferential direction to form a horizontally elongated elastic piece, and a projection is formed on the outer surface of the free end of the elastic piece.
