[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic container, and more particularly, to a container body and a lid body which are openably and closably connected at respective rear portions thereof, and a concave portion is provided at a front edge of the container body. And a push piece urged forward by an elastic member is disposed in the recess so as to be able to move back and forth, and a claw is formed at the front edge of the lid to close the lid. Sometimes, the pawl engages the push piece to occupy the closed position, and when the push piece is pressed rearward in the closed position, the engagement between the push piece and the pawl is released. The present invention relates to a cosmetic container that has been made.

[0002]

2. Description of the Related Art In a cosmetic container of this type, a push piece is slidably mounted in a recess provided at a front edge of a container body, and the front surface thereof is used as a push button. By arranging a spring inside the push piece, the push piece is normally urged in the protruding direction so as to engage with a claw piece provided on the lid to maintain a closed state, and press the push button part. By doing so, the engagement with the claw piece is released, and the lid can be opened.

[0003]

In such a cosmetic container, a conventional leaf spring having a curved shape is disposed as a spring, and both ends of the leaf spring abut against the concave side or the inside of the push piece, and the center portion is formed. Is brought into contact with the other side to obtain spring elasticity. This configuration is due to the fact that the stroke of the push piece cannot be sufficiently taken between the recess and the push piece.

However, in such a structure, when the push piece is formed to be long in the width direction of the container body in order to improve the appearance of the container and enhance the opening and closing operability, the push piece is biased toward the spring elasticity by the pressing position. May occur and may not open properly.

[0005] That is, when pushing the push piece,
If the push piece is pushed into the approximate center, the spring pressure is evenly generated in the left and right directions, the push piece moves in parallel and the engagement with the claw is released, but when the end of the push piece is pushed in, the spring pressure is reduced. There has been such a problem that deviation occurs, the opposite end is not pushed in, is caught on the claw piece, and the disengagement cannot be performed well.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a push-piece which, when any part of the push-piece is pushed in, can be disengaged normally from the push piece. It is an object of the present invention to provide a cosmetic container that can increase the degree of freedom of selection in adjusting the pushing and returning strength of pieces.

[0007]

According to the present invention, in order to achieve the above object, a container body and a lid are connected to each other at their rear portions so as to be openable and closable, and a recess is formed in a front edge of the container body. A push piece that is urged forward by an elastic member is disposed in the recess so as to be movable forward and backward, and a claw is formed at the front edge of the lid to close the lid when the lid is closed. The claw piece engages with the push piece to occupy the closed position, and when the push piece is pressed rearward in the closed position, the engagement between the push piece and the claw piece is released. In the cosmetic container, the elastic member is formed of a pair of left and right rubbers in the form of a tube in which the front and rear ends are in contact with the inner surface of the push piece and the inner part of the recess, and the center of each is defined by the inner surface of the push piece or the container body. A pair of guys protruding into the recess Characterized in that the shaft is one that is fitted and held.

Accordingly, in the present invention, spring elasticity is generated by the expansion and contraction of the pair of left and right rubbers. Further, since the rubber is held by the pair of guide shafts, the rubber pieces are pushed in parallel regardless of the position where the push piece is pushed, without any deviation depending on where the push piece is pushed, so that the engagement is normally released. Further, the adjustment of the pushing and returning strength can be freely performed by adjusting the hardness, diameter and length of the rubber.

Further, in the present invention, a guide shaft and a bearing are inserted into the inner surface of the push piece and the recess of the container body, respectively, and the rubber is provided on the outer periphery of the guide shaft. By providing a configuration in which the end face is in contact with the bearing portion by being fitted, the bias due to the pressed portion with respect to the push piece is further eliminated, and a normal disengagement operation can be performed.
