Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a paper container in which a synthetic resin film is stuck on the entire inner surface and a side dish is put therein.

[0002]

[Prior art]

 A conventional example suitable for comparison with the present invention is a paper container shown in FIG. In the paper container, the inner and outer plates 3 and 5 connected to the bottom plate 1 are folded inward and outward, and the insertion flaps 7 and 9 provided on both side plates are perpendicular to the inner and outer plates 3a. It is designed to be assembled by inserting it between the stacking plates 5a.

[0003]

[Problems to be solved by the device]

 In the paper container described in the above-mentioned prior art, one side of one flap 9 is usually separated from the side plate 3a by the notch S in order to allow the movement of the flaps 7 and 9 when inserted, but the problem is Due to this separation, the film is inevitably cut together with the cut S, and the cut film portions are overlapped with each other, and there is a drawback that juice such as prepared foods leaks from the overlapped portion.

In view of the above, the present invention provides a structure for assembling a container without cutting the film, and an object thereof is to eliminate the drawbacks such as juice leakage that have occurred in the past.

[0005]

[Means for Solving the Problems]

The present invention for achieving the above object comprises a paper board A, and a base plate C having a synthetic resin film B adhered to the entire one surface of the paper board, a bottom board 1 and each side of the bottom board 1. Inner plates 3 and 3a connected to each other via parallel folds 2 and 2a, and outer plates connected to the inner plates 3 and 3a via folds 4 and 4a parallel to the folds 2 and 2a. The plates 5 and 5a, the outer insertion flap 7 that is connected to the end of the outer plate 5 via a fold line 6, and the inner flap that is connected to the end of the inner plate 3 via a fold line 8 In the paper container configured with the inserting flap 9, the inner inserting flap 9 is formed by cutting off all or part of the paper board portion on the back side of the flap portion, leaving only the film B ₁ portion of the flap portion. The gist is that the film B ₁ portion is concealed in the space created by the excision.

[0006]

【Example】

FIG. 1 shows a developed state of the paper container. A paper plate A and a base plate C formed by adhering a synthetic resin film B to the entire one surface of the paper plate. A bottom plate 1 and each side of the bottom plate 1 with fold lines 2 and 2a parallel thereto. Ends of the inner plates 3 and 3a connected to each other, the outer plates 5 and 5a connected to the inner plates 3 and 3a via the fold lines 4 and 4a parallel to the fold lines 2 and 2a, and the outer plate 5. Made of paper, which is composed of an outside insertion flap 7 that is connected to the end portion through a fold line 6 and an inside insertion flap 9 that is connected to an end of the inner plate 3 through a fold line 8 a container, insertion flap 9 of the inner, leaving only film B ₁ part of the flap portion excised all or part of the paper plate portion of the rear side, the film B ₁ part in a space generated by the excision Minutes are concealed.

[0007]

[Function of the device]

 As an assembling method, the inner side plates 3, 3a, 5, 5a are bent inward and outward along the fold lines 2, 2a, 4, 4a and glued to form double side walls standing upright on four sides. In addition, the inner and outer insertion flaps 7 and 9 are bent through the fold lines 6 and 8, and the flaps are overlapped and inserted into the orthogonal standing side walls to assemble a container as shown in FIG. There is no difference in the general form of this type of container used, but the features of the present invention are as follows.

That is, of the inner and outer insertion flaps 7 and 9, the flap 9 has the entire paper board portion on the back side thereof cut off, leaving only the film B ₁ corresponding to the flap 9 _{1. In order} to insert 1 between the outer plates 3a and 5a in the upright state, glue about half the length range of the film B ₁ near the flap 7 to the flap 7 and insert the flap 7 in this state. The unbonded film B ₁ portion near the inner plate 3a is naturally inductively pushed between the inner and outer plates 3a, 5a as shown in FIGS. 3 and 4, and the pressed film B ₁ portion is pleated. Since it is interposed between the inner and outer plates 3a and 5a, and is also in the state of being continuous in a pleated shape, the cause of juice leakage is eliminated. The flap 7 is, of course, adhesively fixed between the inner and outer plates 3a and 5a.

FIG. 6 shows a second embodiment. In this example, about half the area of the flap 9 near the inner plate 3 is left, the remaining area is cut off, and the cut-off portion is covered with the film B _1. When 9 and 9 are polymer-bonded and inserted between the inner and outer plates 3a and 5a as in the previous example, the film B ₁ is inductively pushed by itself, and is interleaved in the inner and outer plates 3a and 5a in a folding manner. , Can eliminate the cause of spillage.

[0010]

[Effect of device]

As described above, according to the present invention, the following effects can be obtained. (A) The insertion flap 9 on the inner side cuts out all or part of the paper board portion on the back side thereof, leaving only the film B ₁ corresponding to the flap, and the film B ₁ portion in the space created by this cutting. The film B can be interposed between the side plates 3a and 5a in a folded shape by an extremely simple structure in which the film is concealed, and because of the folded shape, there is no joint portion due to a conventional cut, so that the cause of the leakage of juice is caused. Can be wiped out. (B) Since the film B ₁ follows well when inserting the flap 7 between the side plates 3a and 5a, the insertion workability can be simplified.
