  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is given in detail, giving an Example, referring drawings. The packaging container of the present invention is formed by cutting a sheet of paper or synthetic resin into a predetermined shape and bending it. Resins such as polyethylene terephthalate (PET), polypropylene (PP), and polyvinyl chloride (PVC) are used for the synthetic resin sheet.

  A packaging container 1 according to a first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a perspective view of the packaging container 1, and FIG. 2 shows a development view of the packaging container 1. Sheet-shaped paper is used for the packaging container 1 in the present embodiment.

  As shown in the development view of FIG. 2, the packaging container 1 of the present embodiment is configured by bending one sheet of paper, and includes a front plate member 2, a back plate member 3, side plate members 4 a and 4 b, and a bottom plate member 6. The cover plate member 5, the reinforcing members 7 a and 7 b, and the adhesive margin piece 13 are provided. The bottom plate member 6 is composed of four bottom plate member pieces 6a, 6b, 6c and 6d.

  A method for molding the packaging container 1 will be described below. The packaging container 1 in a state of being cut as shown in FIG. 2 is bent and folded at mountain fold lines 8a, 8b, 8c, 8d, 8e, 8f, 8g, and 8h, so that the boundary of each member Is partitioned and molded. Further, the packaging container 1 is subjected to bending processing at the valley fold line 9 in the direction opposite to the mountain fold lines 8a to 8h. Each member having the mountain fold lines 8a to 8h and the valley fold line 9 as a boundary is arranged such that an angle between adjacent members is substantially a right angle. Further, the packaging container 1 is fixed so that the angle formed between the front plate member 2 and the side plate member 4b is almost a right angle by applying an adhesive to the adhesive margin piece 13 and fixing it to the end of the side plate member 4b. Is done. By the above molding process, the side surface of the packaging container including the front plate member 2, the back plate member 3, and the side plate members 4a and 4b is formed.

  A method in which the bottom plate member 6 is formed by the bottom plate member pieces 6a, 6b, 6c, and 6d will be described. The protrusions provided at the tips of the bottom plate member piece 6b and the bottom plate member piece 6d are inserted into the concave portion at the tip of the bottom plate member piece 6c, and the convex portion at the tip of the bottom plate member piece 6a from the outside is the tip of the bottom plate member piece 6c. The bottom plate member pieces are combined with each other, and the bottom plate member pieces 6a, 6b, 6c, 6d form a substantially flat bottom plate member 6.

  By forming the bottom plate member 6 by a combination of the bottom plate member pieces 6a, 6b, 6c, 6d, the front plate member 2 connected to the top of the bottom plate member piece 6a, the side plate member 4a connected to the top of the bottom plate member piece 6b, The back plate member 3 connected to the upper part of the bottom plate member piece 6c and the side plate member 4b connected to the upper part of the bottom plate member piece 6d are arranged so that the angles formed by the members adjacent to each other are substantially perpendicular. Further, the fold line 8e is bent so that the lid plate member 5 and the front plate member 2 are perpendicular to each other. As a result, the space surrounded by the front plate member 2, the back plate member 3, the side plate members 4a and 4b, the lid plate member 5, and the bottom plate member 6 is a substantially rectangular parallelepiped. That is, the housing 10 is formed by the front plate member 2, the back plate member 3, the side plate members 4 a and 4 b, the lid plate member 5, and the bottom plate member 6.

  The side of the back plate member 3 is formed longer than the side of the front plate member 2. For this reason, when the accommodating part 10 is formed by molding, the upper part of the back plate member 3 extends above the upper side of the front plate member 2 and the lid plate member 5. The portion extending above the back plate member 3 is subjected to a bending process, whereby the hanging portion 11 is formed. In the present embodiment, the suspending portion 11 folds the portion of the back plate member 3 located above the cover plate member 5 into a mountain fold with a mountain fold line 8h, and further with a valley fold line 9 into a valley fold. It is formed by doing. By performing such a bending process, the suspending part 11 is constituted by a part of the back plate member 3 in a double overlapping state, and the strength is higher than the other parts. The hanging part 11 supports the weight of the packaging container and the stored article when the packaging container 1 is hung on a hook or the like for display or storage. In the center of the suspending portion 11 in this embodiment, a suspending hole 12 for engaging with a hook or the like penetrates. The suspension hole 12 is provided at the center of the suspension portion 11 so that the distances to the side plate members 4a and 4b are equal.

  The shapes of the reinforcing members 7a and 7b in the present embodiment are substantially right-angled isosceles triangles. The reinforcing member 7a is arranged at a position where the bottom side is connected to the upper side of the side plate member 4a and the side perpendicular to the bottom side is connected to the side side of the back plate member 3a. The reinforcing member 7b is disposed at a position where the bottom side is continuous with the upper side of the side plate member 4b and the side perpendicular to the bottom side is continuous with the side side of the back plate member 3b. Note that the “substantially right-angled isosceles triangle” referred to here means that the length of the side is not exactly the same because it includes an error during molding, and the angle is not exactly a right angle. A triangle that is recognized as an equilateral triangle.

  In the packaging container 1 of the present embodiment, the reinforcing member 7a is formed by extending the paper that is integral with the side plate member 4a and the back plate member 3 on the upper side of the side plate member 4a. For this reason, as compared with the case where members are joined by bonding or a combination of hook portions, higher strength that can resist an external force or moment from an arbitrary direction is secured. Similarly to the reinforcing member 7a, the reinforcing member 7b is also formed of paper that is integral with the side plate member 4b and the back plate member 3, and thus has excellent strength.

  The effect of the reinforcing members 7a and 7b in the packaging container 1 of the present embodiment will be described. The packaging container 1 according to the present embodiment suspends the entire packaging container 1 through the hanging hole 12 of the hanging part 11 on a horizontal bar or the like of the display shelf in a state where the article is accommodated in the accommodating part 10 to display and store the article. Used to do. An administrator or a purchaser holds either the container 10 or the hanging part 11 and puts the packaging container 1 in and out of the display shelf. At this time, the container 10 and the hanging part 11 are twisted. There is a possibility that either one of them may be deformed or a part of the back plate member 3 that becomes a boundary between the housing portion 10 and the suspension member 11 may be bent. However, the packaging container 1 of the present embodiment has such a twist and bend in advance by the reinforcing members 7a and 7b that connect the upper sides of the side plate members 4a and 4b and the side sides 3a and 3b of the hanging part 11. It is possible to prevent.

  When the reinforcing members 7a and 7b are not provided, the angle formed by the upper sides of the side plate members 4a and 4b and the side sides 3a and 3b of the suspending portion 11 is a right angle. When the portion 10 is pulled, stress concentration occurs at the point where the upper sides of the side plate members 4a and 4b intersect with the side sides 3a and 3b of the suspended portion 11, and the container may be damaged. However, since the reinforcing members 7a and 7b of the present embodiment are arranged at positions where such stress concentration is expected, the stress concentration generated in advance is reduced or avoided, and the housing portion and the suspension portion 11 The risk of tearing or breakage between the housing portion 10 is prevented in advance.

  Thus, the packaging container 1 of the present embodiment has a substantially right-angled isosceles triangle that connects the upper sides of the side plate members 4a and 4b and the side sides 3a and 3b of the hanging portion 11 of the back plate member 3, respectively. By providing the reinforcing members 7a and 7b, even when the article is suspended and stored or sold in a state where the article is accommodated, the boundary between the article accommodating portion 10 and the suspended portion 11 is damaged. Or the risk of deformation.

  In the present embodiment, the development of the packaging container shown in FIG. 2 is such that the front plate member 2 and the side plate member 4b are separated, and the glue provided at the end of the front plate member 2 is shown. The example in the case where a packaging container can be formed by fixing the edge part of the side plate member 4b to the margin piece 13 is shown. However, the position of this separation may be the position of the mountain fold line 8b, and the arrangement of each member can be changed as appropriate. Furthermore, the arrangement of the glue margin piece 13 can be changed as appropriate.

  In the present embodiment, the bottom plate member 6 is formed by combining four bottom plate member pieces 6a, 6b, 6c, and 6d. However, the bottom plate member 6 is formed by one piece. In addition, it is possible to form two bottom plate member pieces in combination. Even when the bottom plate is formed by four pieces of the bottom plate member pieces, the shapes of the convex portions and the concave portions for the combination can be appropriately changed. Moreover, it is also possible to reinforce the whole or a part of the bottom plate as a double structure by providing a bent portion in the bottom plate member 6 or ensuring a wider overlap of the bottom plate member pieces.

  Furthermore, in this embodiment, the packaging container 1 formed by bending one sheet of paper has been described. However, the front plate member 2, the back plate member 3, and the side plate member 4a are made of two or more sheets of paper or synthetic resin. 4b, the bottom plate member 6, the lid plate member 5, and the reinforcing members 7a and 7b, respectively. When the packaging container 1 is formed by laminating two or more sheets, a paste margin piece is provided at the end of one of the two members to be bonded. The packaging container 1 can be formed by applying an adhesive to the substrate and performing adhesion.

It is arranged at a position shifted from the center position. The other materials constituting the packaging container 21 and the arrangement and molding method of each member of the packaging container 21 are the same as those of the packaging container of the first embodiment, and redundant description is omitted.

  The packaging container 21 of the present embodiment is particularly preferably used when the hanging hole 23 is locked to a hook or the like in a state in which an article having a non-uniform weight distribution is accommodated on the left and right. The position of the suspending hole 23 of the packaging container 21 in this embodiment is the weight of the article located on the right side (the side closer to the side plate member 24a displayed on the right side in FIG. 3) than the suspending hole 23, and the suspending hole 23. It is provided at a position where the weight of the article located on the left side from the hole 23 (displayed on the left side in FIG. 3 and closer to the side plate member 24b) is balanced. In this way, by optimizing the position of the suspending hole 23 according to the distribution of the weight of the article to be accommodated, the attitude of the entire packaging container 21 can be kept horizontal. A favorable impression can be given.

  A packaging container 31 which is a third embodiment of the present invention will be described. FIG. 4 shows a perspective view of the packaging container 31. In the packaging container 31 of the present embodiment, the lateral width of the side plate member 33 is formed wider than that of the packaging container 1 of the first embodiment, and therefore the entire depth is longer.
