Description

  The present invention relates to a lid that may be soiled or damaged when it is opened and closed directly by hand, a lid that has a structure or situation that is difficult to open and close by hand, and a lid that should be closed immediately after opening. The present invention relates to a lid opening / closing device such as a cosmetic container, a trash container, a volatile material container, a stamp stand, etc.

A lid opening / closing device is known in which a lid is opened and closed with a single push button (see Patent Document 1).
In this lid opening / closing device, when the push button is pushed against the return elasticity of the elastic member, the tip of the push rod member presses the opening groove of the lid at a distance close to the push button, and the lid is hinged. When the push button returned by the return elastic force of the elastic member is pushed in again, the tip of the push rod member presses the closing groove located at a close distance when the lid closes. Then, the lid body is configured to rotate and close around the axis of the hinge connecting portion, and at this time, the opening / closing switching member is a lid body in which the tip of the push rod member is closed as the lid body is opened / closed The opening groove and the closing groove of the lid body in the open state are switched and engaged.
