Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a compact container, and more specifically, the hinge pin is inserted into the hinge pin insertion holes formed in the rear part of the container body and the lid body so that the hinge pin can be opened and closed independently. The present invention relates to a compact container in which a hook is provided at the front end of the container body and the lid.

[0002]

[Prior Art]

 BACKGROUND ART Conventionally, a compact container is configured by connecting a container body that stores cosmetics and a lid that opens and closes the container body via a hinge portion.

By the way, various modifications have been made to the hinge portion of the compact container so that not only the hinge function but also the lid body can be automatically rotated with a biasing force. , Its opening and closing operation is convenient.

For example, in Japanese Utility Model Laid-Open No. 59-13206, when the lid is closed, the rear end of the lid is slightly lifted via a levitation means, and the hinge pin is deformed by this lifting so that the lid is attached to the lid. A device configured to provide a biasing force in the opening direction is disclosed. Therefore, in this compact container, when the hook is released in the closed state of the lid, the lid is automatically slightly opened by the biasing force in the opening direction of the lid caused by the deformation of the hinge pin.

[0005]

[Problems to be solved by the device]

 However, in such a conventional compact container, the hinge pin is elastically deformed by pressing the rear end of the lid upward and slightly lifting it, thereby generating a biasing force in the opening in the lid. ing. Therefore, when the lid is closed, a vertical gap may be created between the lid and the container body due to the levitation means, which may impair the hermeticity of the container and warp the lid. There was a problem that such unreasonable force acted. There is also a problem in that the thickness of the compact container is increased due to the levitation means that is vertically interposed between the lid body and the container body with a considerable thickness.

The present invention has been made in view of the above conventional problems, and an object thereof is to open the lid on the hinge pin and the flexible portion without forming a vertical gap between the lid and the container body. With a structure that generates a biasing force in the direction, it is possible to secure a sufficient opening amount of the lid when the hook is released, and to prevent the lid from being subjected to unreasonable force while maintaining the tightness of the container. Another object is to provide a compact container that can be made thin.

[0007]

[Means for Solving the Problems]

 To achieve the above object, according to the present invention, the hinge pin is inserted into the hinge pin insertion holes formed in the rear portion of the container body and the lid body so as to open and close, and the container body is attached. In a compact container in which a hook is provided at the front end of the lid, a flexible portion that can be elastically deformed in the vertical direction is formed at the rear end of the container body, and when the lid is closed. It is characterized in that a projection for elastically deforming the hinge pin to urge the lid in the opening direction is provided between the flexible portion of the container body and the lower surface of the lid.

[0008]

[Action]

 In the compact container of the present invention having the above configuration, when the lid is closed, the lid moves downward, and the protrusion causes the flexible portion and the hinge pin to elastically deform, so that the lid is opened. A bias can be given. Therefore, by releasing the hook when the lid is closed, the lid can be automatically opened by a sufficient predetermined amount by the biasing force of the flexible portion and the hinge pin.

Further, it is possible to prevent an upward and downward gap from being formed between the lid body and the container body by the flexible portion that is elastically deformed in the vertical direction, and to apply an unreasonable force to the lid body. It can also be prevented from acting. In addition, the thickness of the compact container can be reduced.
