BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container with a lid which can be opened with one hand to form a lid integrally formed with a container body.

[0002]

2. Description of the Related Art Conventionally, there has been a one-push open cap mechanism disclosed in Japanese Patent Application Laid-Open No. 10-338256 as one which can open a lid of a container with one hand. In this configuration, a male and female hook mechanism that forms a wedge is provided on each of the cap body and the lid on the rotation side of the lid. The cap body has an extraction port inclined in the direction of rotation of the lid, and the lid has a plug formed to fit into the extraction port. Further, a pair of slits are provided so as to cross the hinge portion from the cap body side to reach the lid portion, and both ends of the pair of slits are respectively provided with hinge grooves which are bending lines. Between the pair of slits is a pressing operation unit.

The one-push open cap mechanism can be opened by pressing the pressing operation portion in the rotating direction, the lid portion is advanced in the rotating direction, the hook mechanism is released, and at the same time, the lid is inclined in the rotating side direction. The stopper part moves open within the extraction port formed at the same inclination angle. Further, the diagonal distance connecting the hinge part on the cap body side and the bent part of the lid part is extended by linearizing the pressing operation part, and the pressing force causes the lid part to pivot about the bent part and the lid part and the plug part. Is released.

Japanese Patent Application Laid-Open No. 7-132965 discloses a case in which a thin main body and a lid are integrally formed via a hinge and can be opened with one hand. . In this case, the main body and the lid are connected by a pair of connecting portions, and a pressing operation portion is provided between the pair of connecting portions.

Then, when the male hook is pushed inward from both sides, the male hook is pushed inward to disengage the female hook of the lid and the lid becomes free. Here, when the pressing operation portion is further pushed in, the pressing operation portion is deformed so as to be bent inside the case. Then, since the angle formed by the pressing operation unit and the lid becomes smaller, the lid is opened to eventually return to the original angle. Actually, these operations are performed in one operation (one push), that is, simultaneously.

[0006]

The one-push open cap mechanism disclosed in Japanese Patent Application Laid-Open No. 10-338256, which is the former of the prior art, requires that the pressing operation part be strongly pressed obliquely when opening.
