DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS.
This will be described in more detail with reference to FIGS. Reference numeral 1 denotes a lid, which is provided with a hinge portion at the rear, a U-shaped lock portion 3 at the front, and a lid 1 at the front.
A pressing piece 6 rotatably supported on the front surface of the device is disposed. The pressing piece 6 is provided with an action portion 7, which passes between the U-shaped lock portions 3 and passes through the lock portions 3.
And the lower surface 9 of the action portion 7 are in contact with each other. The upper surface 8 of the lock portion 3 and the lower surface 9 of the action portion 7 are in a state of being uneven or inclined, and are engaged with each other. Here, in the case of an uneven surface or an inclined surface, the upper surface 8 has the pressing piece 6 side in the upper position. Reference numeral 2 denotes a bottom body, on which a hook portion 5 is erected on the front surface, and the front surface is formed as a concave step portion 4 and a hinge portion for hingedly fitting with the lid 1 is provided at the rear. When the lid 1 is closed, the hook 5 is in contact with and engaged with the upper surface of the lock portion 3 of the lid 1. Inside the bottom body 2, an impregnated body such as an ink or a lotion for a stamp stand or a cosmetic compact, and a middle container for accommodating a stamp case are incorporated. In the present application, a stamp stand, a makeup compact, and the like are particularly shown in the drawings. Therefore, a frame body 20 for holding the impregnated body is provided at the open end of the bottom body 2.

Reference numeral 6 denotes a pressing piece, and a shaft 12 is stretched on both side surfaces. The shaft 12 is provided on the lid 1 and supported by a bearing 13 to rotate. Further, the pressing piece 6 is provided with an action portion 7 which passes between the U-shaped lock portions 3 and abuts on the upper surface 8 of the lock portion 3 to wind the lock portion 3. The lower surface 9 of the action portion 7 and the upper surface 8 of the lock portion 3 are always in contact. In FIG. 5, a stopper 15 is provided on the lid 1 so that the pressing piece 6 does not turn counterclockwise in FIG. 5, and is in contact with the upper part of the pressing pressure piece 6. Then the use of this container is
When the lid 1 and the bottom 2 are engaged, the lock 3 provided on the front of the lid 1 and the hook 5 provided on the front of the bottom 2 are engaged. An operating portion 7 is provided on a pressing piece 6 which is provided at an intermediate position between the front surface of the lid 1 and the bottom 2 and which is supported by the bottom 2 and which is rotatable.

The upper surface of the lock portion 3 has a pressing one side at an upper position to facilitate transmission of rotational power. Next, when a pressing force is applied with a finger or the like toward the rear from the front surface of the pressing piece 6, the operating portion 7 winds the lock portion 3 in the same direction as the rotation direction, and the engagement between the hook portion 5 and the lock portion 3 is established. It is released. Here, since the lock portion has a U-shape and has a resiliency as compared with a flat plate, a force to return to the original position with the action portion 7 acts. Then, since the lid 1 is already slightly raised by a finger or the like, the hook portion 5 and the lock portion 3 do not mesh with each other.

Here, if an elastic body such as a torsion spring is attached to the hinge fitting portion at the rear end of the lid 1 and the bottom 2 in a direction in which the lid 1 and the bottom 2 are opened from each other, this force causes the lid 1 to be opened. Since 1 is raised upward, the engagement is further easily released. The attachment of the elastic body such as the torsion spring is not particularly limited. When the lock portion 3 and the hook portion 5 are engaged again, the lower curved surface 11 of the lock portion 3 moves along the hook portion 5 and is engaged by pushing the lid 1 downward. Next, a second embodiment of the present invention will be described in detail with reference to FIG. Reference numeral 3A denotes a U-shaped lock portion, in which the upper surface 8A and the hook portion 5 are in abutting engagement, and a lower portion is provided with a fishing catching portion 10. Reference numeral 6A denotes a fishhook-shaped pressing piece. A shaft 12 is stretched on both side surfaces and is rotatably supported by a bearing 13 of the lid 1. The action portion 7A, which is the tip of the pressing piece 6A, is engaged with the fishing receiving portion 10. Further, a lower portion of the action portion 7A is provided with a lower curved surface 11A.
When the lid 1 is closed, the lower curved surface 11A moves along the hook 5 and engages again. The lid 1 is opened to rotate.
