2. Description of the Related Art As a conventional liquid paper container of this type, a so-called gobel top type liquid paper container as shown in FIG. 5 is known. This gobel top type paper container 1 is generally widely used as a container for milk, juice, sake, liquid fertilizer and the like. The Gobel top type liquid paper container 1
The structure is as follows: the sloping roof lid 2 on each of the corresponding sides, the triangular folding plate 4 connected to both shoulders of the triangular upright lid 3, and the joint sticking piece 5.
The roof type lid 6 consisting of is provided in the upper opening of the rectangular tube container 7 and is configured.

When the liquid contained in the Gobeltop type liquid paper container 1 is taken out, as shown in FIG. 5, a part of the joint-attaching pieces 5 attached to each other is peeled off, and a sloping roof is formed. The triangular standing lid 3 and the triangular folding plate 4 that were folded on the back side of the lid 2 are pulled out to the sides of the sloping roof lid 2 to form a spout a, and a container is formed from this spout a. The liquid contained inside was being poured out. In addition to the conventional example,
In particular, a Gobel top type liquid paper container for storing sake or the like has a plastic spout formed separately attached to the sloping roof lid 2 (not shown), and the cap of the spout is opened to open the inside of the container. The storage liquid was poured out and taken out.

[0004]

When taking out the stored liquid, however, as in the former case, a part of the joint-attaching patch 5 attached to each other is peeled off, and further folded on the back side of the sloping roof lid 2. It takes some skill to pull out laterally while peeling off the joint between the triangular standing lid 3 and the triangular folding plate 4 to form the spout a, which is smooth for children and inexperienced people. There was a problem that it could not be carried out and the spout a was deformed. Also, a container having a structure in which a part of the spout a is folded in an open state without being adhered is known so that the spout a can be easily configured. However, there was a problem such as a cause of liquid leakage.

[0007] Further, the latter method of attaching a plastic spout has a problem that the structure is complicated and the cost is high, and the plastic spout is projected outward, so that it is stored. In addition, there is a problem that it is an inconvenience because it becomes an obstacle during transportation, and that the cap is lost and the cap is not closed. The liquid paper container according to the present invention is a new technique developed in view of the above-mentioned conventional problems, and particularly, it can easily and surely open a part of a triangular standing lid that is folded on the back side of a sloping roof lid. The purpose of the present invention is to provide a completely new liquid paper container having a possible spout.

[0006]

The liquid paper container according to the present invention is a technique which has fundamentally improved the above-mentioned conventional problems, and its gist is to provide a sloping roof lid and a triangular upright on the corresponding sides. A roof-shaped lid consisting of a lid and a triangular folded plate connected to both shoulders of the triangular standing lid, and a roof-shaped lid composed of a sloping roof lid and an affixing patch attached continuously to the upper ends of the triangular folded plate In a Gobel top type liquid paper container having a part, a front half-cut peeling piece is formed by forming a half-break line of a predetermined shape on the front side of the triangular standing lid, and the inside half half-cut peeling piece is formed. A liquid paper container characterized in that a back half-cut opening piece is formed by forming a half-break line of a predetermined shape on the back side.

[0007]

As described above, the liquid paper container according to the present invention has a front half cut-off strip and a back half on the back side of the front half-cut strip at a predetermined position of the triangular standing lid that is folded on the back side of the inclined roof lid. Since a cut opening piece is provided, by opening one side of the sloping roof lid on both sides to both sides, the triangular standing lid on the back side is exposed, and then the front side half-cut peeling piece is left around a part. By peeling from the back side half-cut piece, the back-side half-cut opening piece provided on the back side of the front-side half-cut peeling piece can be simultaneously separated from the surroundings, and the spout can be automatically formed in the portion corresponding to the back side half-cut opening piece. ..

As described above, the front half-cut piece that has been peeled off with a part left is returned to its original state, so that the back half-cut opening piece projecting on the back side is fitted into the spout and the spout is opened. It can be closed. Further, by returning the sloping roof lids on both sides that have been folded sideways to the upper side of the triangular standing lids, the front side half-cutting peeling can be performed with the sloping roof lids and the triangular bending plates connected to the sloping roof lids. The piece is completely covered and pressed, which prevents the front half-cut peeling piece from rising and opening the pouring opening.
