Description

  The present invention relates to a feeding container that mainly contains a stick-shaped cosmetic that can expose an appropriate amount of lipstick, lip balm, stick eye shadow, stick foundation and the like. The contents stored in such a feeding container, that is, the materials to be fed, are typically formed in a relatively soft stick shape such as lipstick or lip balm. Finishes such as shadows, blushers and creams (base, whitening, cleansing, etc.) or cosmetics for the skin, cosmetics for hair such as hair styling, hair coloring, hair treatments, special-use cosmetics such as sunscreens or tans There are various uses such as office supplies such as stick glue, socks stoppers, anti-fogging and scratch repair materials as car accessories, stains, and miscellaneous goods such as shoe ink.

  As shown in FIG. 1, in this type of feeding container, the receiving tray 5 moves up and down along the spiral groove 3a in the inner cylindrical portion 4 by rotating the inner cylindrical portion 4 relative to the outer cylindrical portion 3. It is possible. 2A, the position of the spiral groove 3a is provided in the lower part of the container body 1, and in FIG. 2B, the position of the spiral groove 3a is provided in the upper part of the container body 1. (Patent Document 1) Further, there is a container in which the spiral groove 3a is replaced with a screw to serve as a driving means. (Patent Documents 2 and 3)

  As described above, the feeding container is widely used because of its excellent portability. In recent years, diversification has been promoted, such as softer cosmetics and thinner cosmetics used as stick cosmetics. Softer bar-shaped cosmetics and thinner bar-shaped cosmetics than conventional products are more likely to be defective even during folding, deformation, storage, and transportation during use.

  In the case of the container in which the position of the spiral groove 3a is provided in the upper part of the container body 1, there is a distance between the container tip and the cosmetic on the application surface, and the cosmetic in use returns to the container. It tends to come out longer from the phenomenon. This type of container is characterized by quick delivery.

  In the case of the container in which the position of the spiral groove 3a is provided in the lower part of the container body 1, since the relatively thin cosmetic is often filled, the spiral pitch is small and the operation is troublesome. There is a feature that it is easy to apply because there is no distance between the surface and the cosmetic application surface.

  As a cause of breakage or deformation during use, it can be considered that it is extended for a long time. As a cause of breakage due to storage, transportation, etc., it is considered that the boundary between the inside and outside of the saucer 5 is easily broken due to thixotropy due to deformation due to shear impact. Occurrence of folds other than the boundary is a problem not caused by the structure of the container.

  Therefore, the present invention prevents bending and deformation during use, softens the shear impact, and keeps the resistance that the receiving tray 5 in use cannot return to the inside of the container at an appropriate strength that is not too strong and not too weak. It is an object of the present invention to obtain a feeding container having a structure that can be used.

In order to solve the above problems, the present invention is provided with a spiral groove 3a on the inner peripheral surface of the outer cylinder portion 3 of the container main body 1 composed of a cap and an outer cylinder portion 3 provided with a cap mounting portion 3b. A housing portion 4a and an inner cylinder portion 4 having a guide hole 4b in the vertical direction at the lower portion are accommodated in the outer cylinder portion 3 so as to be relatively rotatable. The receptacle 5 provided with the main protrusion 5a that engages with the spiral groove 3a is accommodated, and the inner cylinder portion 4 is rotated relative to the outer cylinder portion 3 so that the receptacle 5 moves into the spiral groove 3a in the inner cylinder portion 4. In the feeding container that is movable in the vertical direction, a protrusion 6 is formed on the inner periphery of the inner cylinder portion 4, and an engaging portion 7 that can be engaged and disengaged in the vertical direction with respect to the protrusion 6 is provided on the tray 5. Formed on the outer periphery, the protrusion 6 and the engaging portion 7 can be engaged and disengaged by relative elastic deformation.

  In this way, by allowing the protrusion 6 and the engaging portion 7 to be engaged and disengaged with each other by relative elastic deformation, the resistance during operation is not too strong and not too weak. You can keep it.

  The relative elastic deformation of the protrusion 6 with respect to the engaging portion 7 is possible by providing a bending space on the front end surface side of the protrusion 6 or the engaging portion 7.

  Furthermore, by forming the protrusion 6 or the engaging portion 7 in a wave shape in the vertical direction, the shear impact can be reduced.

  As described above, the present invention prevents breakage or deformation of the cosmetics in use, eliminates the return of the cosmetics in use into the container, and more effectively applies a shear impact in storage, transportation, etc. Can be tempered.
