Description

[Detailed description of the invention] The present invention relates to a simple container formed from a thin sheet of synthetic resin by press processing, vacuum processing, etc., in which the main body and the lid are integrated so that they can be opened and closed via a connecting part. It is an object of the present invention to extremely easily and reliably assemble a lid to a main body of a container.

An embodiment of the present invention will be described below with reference to the drawings.

First, the container 1 is an integrated body 2 and a lid 3 formed by pressing, vacuum processing, etc. a thin sheet made of synthetic resin, and the body 2 and the lid 3, which store the contents, are bent. It is configured to be openable and closable via a molded connecting portion 4.

An outer cylindrical portion 5 whose upper surface is horizontal is provided around the upper end of this box-shaped main body 2, and an outer flange portion 5 corresponding to the front end of the main body 2 on the opposite side from the connecting portion 4. Further in the center of
The finger hook portion 6 is formed in such a manner that the outer flange portion 5 further protrudes forward.

On the other hand, at least the connecting portion 4 of the top plate 7 of the lid body 3
A wall portion 8 is provided hanging down from the front end on the opposite side, but in the illustrated embodiment, this wall portion 8 is provided continuously hanging down to the left and right ends of the top plate 7, so that the lid The body 3 has a substantially box shape.

The wall portion 8 is bent to project outward, and grooves 9 into which the outer flange portion 5 of the main body 2 fits when the lid body 3 is closed are formed on the inner surface of the wall portion 8. has been done.

Furthermore, a finger hook 10 is provided at the lower end of the wall 8 in the shape of a brim in a manner that projects outward. A part of the body outer flange 5 that corresponds to the finger hook 6 is a notch 11, and therefore, when the lid is closed, the finger hook 6 of the body 2 is cut out. is now exposed to the outside.

In the illustrated example, a stepped portion 12 is formed on the top plate 7,
The center portion of the top plate 7 protrudes upward, increasing the volume of the container 1 itself.

In a container having such a structure, in the present invention, since the container 1 itself is molded from a synthetic resin thin plate, elastic deformation is extremely easy, and the outer flange 5 of the main body is moved upward and the lid wall is 8
The finger hook pieces 10 are connected to the finger hook portions 6 so as to elastically deform outward respectively.
By vertically shifting the outer flange 5 and the groove 9, the outer flange 5 is disengaged from the groove 9 and the lid can be opened.

In this case, since the finger hook part 6 is exposed by the notch part 11, it is easy to put the finger on it, and therefore the lid opening operation is easy.

Moreover, since the connecting portion 4 between the main body 2 and the lid 3 is simply formed by bending a thin plate, the lid 3 opens upward to the extent that it will naturally return to its original state simply by undoing the above-mentioned fitting due to the elastic return of this portion. It is.

To close the lid, simply push down the lid 3 from above against the elasticity of the connecting portion 4, the outer flange 5 and wall 8 will deform, and the wall 8 will overcome the outer flange 5. In this way, the outer flange portion 5 fits into the groove 9, and the attachment is firmly established.

The present invention has the structure and operation described above.

Therefore, the container itself can be manufactured very easily and inexpensively, the lid can be easily opened and closed, and the lid can be reliably assembled to the main body, among other advantages.
