SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a cup having a lower constriction provided with a lower front plate, a lower rear plate and a pair of lower plates around a bottom plate; A paper container comprising an upper front plate, an upper rear plate and an upper constricted lid provided with a pair of upper plates, and connecting the lower rear plate and the upper rear plate to each other so as to open and close the lid to a cup. When the engaging piece extends from the upper edge of the lower front plate and is folded forward and outward, the locking piece is attached to the back surface of the upper front plate, and when the lid is closed, the upper edge of the cup contacts the inner peripheral surface of the lid. At the same time, the engaging piece engages with the locking piece due to rebound and the lid is locked, and when the engaging piece is pressed against the repulsion, the engagement between the engaging piece and the locking piece is released, and the lid is released. Was opened.

[0007] Such a paper container is excellent in shape retention and openability, and can be recycled and recycled without polluting the environment after disposal.

A side support plate is connected to the upper edge of the lower plate, and when the lid is closed, the lid is supported by the side support plate.

[0009] The engaging piece may extend from the upper plate or from the upper front plate.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS.

The paperboard blank shown in FIG.
And a portion forming the lid 2.
In a portion forming the cup 1, a lower front plate 4, a lower rear plate 5, and a pair of lower plates 6, which are widened toward the distal end, are continuously provided on the periphery of the bottom plate 3. Adhering pieces 7 are provided on both side edges, and side supporting plates 8 are provided continuously on the leading edge of the lower plate 6. An engagement piece 9 is continuously provided at a distal end edge of the lower front plate 4, and an operation piece 10 is protruded from a central portion thereof.

In the portion forming the lid 2, the top plate 11
An upper front plate 12, an upper rear plate 13 and a pair of upper plates 14, which are widened toward the front end, are continuously provided on the periphery of the upper front plate 12. Adhering pieces 16 are respectively provided continuously on both side edges of.

The portion forming the cup 1 and the portion forming the lid 2 are joined by connecting the lower rear plate 5 and the upper rear plate 13,
The top plate 11 is slightly larger than the bottom plate 3. An engagement edge 17 is formed on both sides of the operation piece 10 on the engagement piece 9, and an engagement edge 18 is formed on the locking piece 15 by cutting, respectively.
A concave portion 19 is formed at the center of the front end edge of 2. A window 20 on which a transparent film such as cellophane is stretched is formed in the bottom plate 3, the top plate 11, and the upper rear plate 13.
0 may be omitted.

To assemble the blank, as shown in FIG. 2, the lower front plate 4, the lower rear plate 5, and the pair of lower plates 6 are erected from the bottom plate 3, and the adhesive piece 7 is attached to the inner surface of the lower plate 6. The cup 1 is adhered to form the cup 1, and the upper front plate 1
2. The upper rear plate 13 and the pair of upper plates 14 are erected toward the cup 1, and the locking pieces 15 are attached to the back surface of the upper front plate 12, and the adhesive pieces 16 are attached to the inner surface of the upper plate 14, respectively. Form 2 Here, the engaging piece 9 is folded back outward.

When the lid 2 is closed as shown in FIGS. 3 and 4 after the mini tomatoes and the like are stored in the cup 1, the engaging edges 17, 18 are engaged by the repulsion of the engaging pieces 9, and The lid 9 is locked by the engagement between the piece 9 and the locking piece 15.

At this time, since the lid 2 is narrowed upward, the upper edge of the cup 1 contacts the inner peripheral surface of the lid 2 and the tip of the side support plate 8 contacts the top plate 11. The lid 2 is securely supported without falling.

On the other hand, when the cover 2 is opened, when the operating piece 10 exposed from the recess 19 is pressed against the rebound of the engaging piece 9, the engaging edges 17 and 18 are pushed as shown in FIG. Separated, engaging piece 9
And the engagement piece 15 is released, and the lid 2 is opened.

At this time, since the cup 1 is constricted downward, it is possible to push the operation piece 10 to the back without fail to separate the engaging edges 17 and 18.

Next, a second embodiment of the present invention will be described with reference to FIGS. In this example, the first
The same reference numerals are used for portions corresponding to the respective portions of the embodiment, and only differences from the first embodiment will be described.

This container is made of a blank as shown in FIG. 6, and a locking piece 15 is provided continuously to the leading edge of the upper front plate 12, and is cut out to form an engaging edge 18. Further, in addition to the upper rear plate 13, sticking pieces 16 are continuously provided on both side edges of the upper front plate 12, and in the assembled state shown in FIGS.
Reference numeral 6 is attached to the upper plate 14.

Even with this configuration, the shape is reliably retained, as in the first embodiment described above, and as shown in FIG.
It can be opened and closed with one touch.

[0022]

As described above, in the paper container according to the present invention, the cup of the lower squeeze and the lid of the upper squeeze are connected at the rear end.
When the lid is closed, the upper edge of the cup comes into contact with the inner peripheral surface of the lid, and the engaging piece engages with the locking piece due to repulsion to lock the lid, and pushes the engaging piece against the repulsion. And, since the engagement between the engaging piece and the locking piece is released and the lid is opened, it is excellent in shape retention and openability, does not pollute the environment after disposal, and can be recycled and recycled. You can do it.
