Description

  The present invention relates to a folding paper box used as, for example, a dozen boxes or a decorative box.

  Conventionally, various types of paper boxes of this type have been used, but all of them have a dislike of excessive packaging. Therefore, it is expensive and there is a problem from the viewpoint of resource saving.

  The purpose of the present invention is to solve the above problems, to reduce the amount of paper material, to assemble with one touch, to reduce the cost, and to make the reusable reusable folding paper box environmentally friendly. Is to provide.

  The folded paper box according to the present invention is connected to the first to fourth peripheral wall panels successively forming a square tube, and to the respective rear edges of the second and fourth peripheral wall panels so as to be bent so as to be passed over them. The rear edges of the first and third peripheral panels are separated from the rear edges of the first and third peripheral wall panels, and both edges of the rear end walls respectively corresponding to these edges are separated from each other. .

  In the folding paper box according to the present invention, since the folding operation of the first and third peripheral wall panels and the folding operation of the rear end wall do not interfere with each other, the first and third peripheral wall panels and the rear end wall are folded in two. Thus, the paper box can be folded so that the second and fourth peripheral wall panels are overlapped.

  Further, the first and third peripheral wall panels are formed with first and second vertical bent portions having a U-shaped cross section at the center portions in the width direction, respectively, and the U-shaped cross section is formed at the center portion in the depth direction of the rear end wall panel. When the first and third peripheral wall panels and the rear end wall are each folded in two along the first and second vertical bends and the horizontal bend, for example, the transportation is performed. In storing, the folding paper box can be kept compact without being bulky. Furthermore, by extending each bent portion from the folded state, it can be easily made into an open box state.

  Further, the first and second vertically bent portions may be formed into mountain folds, and the laterally bent portions may be formed into mountain folds or valley folds.

  Further, the first and second vertically bent portions may be formed into valley folds, and the horizontally bent portions may be formed into mountain folds.

  Further, when a vertical seal panel sealed on the outer surface or the inner surface of the free edge of the first peripheral wall panel is provided on the free edge of the fourth peripheral wall panel, the first to fourth peripheral wall panels can be easily formed into a rectangular cylindrical shape. Can be

  Further, the rear edge of the second peripheral wall panel and the connecting edge of the rear end wall therewith are integrally connected, and the connecting edge of the rear end wall with respect to the rear edge of the fourth peripheral wall panel is connected to the fourth edge. The provision of a sealed horizontal sealing panel on the outer or inner surface of the rear edge of the peripheral wall panel makes it possible to reliably and easily transfer the rear end wall to the rear edge of each of the second and fourth peripheral wall panels. it can.

  In addition, the rear edges of the second and fourth peripheral panels and the connecting edge of the rear end wall panel with respect thereto are integrally connected to each other, and the free edges of the first and third peripheral panels are respectively formed. Is provided with a vertical seal panel sealed on the outer surface or the inner surface of the free peripheral portion of the fourth peripheral wall panel, respectively, so that it is troublesome to pass the rear end wall panel to the second peripheral wall panel and the fourth peripheral wall panel. Can be omitted, and the first to fourth peripheral wall panels can be easily formed into a rectangular tube shape.

  Further, a front end wall panel may be flexibly connected to a front edge of the second peripheral wall panel or the fourth peripheral wall panel.

  In addition, if the insertion panel is provided at the front end edge of the front end wall panel, the front end wall panel can reliably keep the upper end openings of the rectangular cylinders formed by the first to fourth peripheral wall panels in a closed state.

  According to this invention, the paper box can be easily folded and assembled in an open state. Furthermore, in the opened state, since there is no portion that overlaps the paper material, the minimum amount of paper material constituting the paper box is sufficient. Therefore, a folding paper box which is inexpensive, does not result in excessive packaging, and is environmentally friendly is provided.

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

  In the following description, the term “front and back” refers to the upper and lower sides in FIG. 1 and the left and right refers to the left and right sides in FIG. 1.

  FIG. 1 shows a state in which the paper box blank is viewed from the outer surface of the paper box. The blanks for the paper boxes are formed by the first to fourth peripheral wall panels 21 to 24, which are sequentially connected via the first to third vertical bending curves 11 to 13 from left to right, and the free edges of the fourth peripheral wall panel 24. A strip-shaped vertical seal panel 25 connected to a certain right edge portion via a fourth vertical folding curve 14 and a front edge portion of the fourth peripheral wall panel 24 via a first horizontal folding curve 31 are the same as the peripheral wall panels 21 to 24. A front end wall panel 41 having a shape, a band-shaped insertion panel 42 connected to the front edge of the front end wall panel 41 via the second horizontal folding curve 32, and a third horizontal folding curve 33 at the rear edge of the second peripheral wall panel 22. A rear end wall 43 having the same shape as each of the peripheral wall panels 21 to 24 and a strip-shaped horizontal seal panel 44 connected to the rear edge of the rear end wall 43 via a fourth horizontal bending curve 34.

  First and second vertical fold lines 51 and 52 extending in the front-rear direction are formed at the left and right central portions of the first and third peripheral wall panels 21 and 23. A horizontal fold line 53 extending in the left-right direction is formed at the center of the rear end wall 43 in the front-rear direction.

  The first to fourth vertical folding lines 11 to 14, the first to fourth horizontal folding lines 31 to 34, the first and second vertical folding lines 51 and 52, and the horizontal folding line 53 are all virtual lines. It may be, or it may be something like a groove that triggers a bend, like a score line.

  FIG. 2 shows an open state of a paper box assembled from the blank shown in FIG. The front end wall panel 41 is open to the near side. The procedure for assembling the blank is as follows.

  First, along the first to fourth vertical folding curves 11 to 14, the first to fourth peripheral walls are arranged such that the panels 21 to 24 and 25 adjacent to each other with the vertical folding curves 11 to 14 form an angle of 90 degrees. The panels 21 to 24 and the vertical seal panel 25 are bent. Next, the outer surface of the vertical seal panel 25 is attached to the inner surface of the left edge of the first peripheral wall panel 21 using an adhesive or the like. Then, the first to fourth peripheral wall panels 21 to 24 and the vertical seal panel 25 are assembled so as to form a rectangular tube. The rear end wall 43 is bent so as to form an angle of 90 degrees with the second peripheral wall panel 22 along the third horizontal bending curve 33, and the horizontal seal panel is formed along the fourth horizontal bending curve 34. 44 is bent at an angle of 90 degrees with respect to the rear end wall 43, and the outer surface of the horizontal seal panel 44 is again adhered to the inner surface of the rear edge portion of the fourth peripheral wall panel 24 using an adhesive or the like. Finally, the front end wall panel 41 and the insertion panel 42 are slightly bent along the first and second horizontal folding curves 31 and 32, and the first to fourth peripheral wall panels 21 to 24 are laid down sideways. The configuration shown in FIG. This is a state where the paper box is opened. The attachment of the vertical seal panel 25 and the horizontal seal panel 44 may be performed such that the inside and outside are reversed.

  Here, it should be noted that there is a slight gap between the rear edge of the first and third peripheral wall panels 21 and 23 and the left and right edges of the rear end wall panel 43. I have. This is important for the folding operation described below.

  Next, how to fold the paper box will be described with reference to FIG. Along the first and second vertical fold lines 51 and 52, the first and third peripheral wall panels 21 and 23 are folded in two such that these portions are mountain-folded. Then, the first and second vertical bent portions 61 and 62 having a U-shaped cross section are formed there. On the other hand, the rear end wall 43 is folded in two so that the horizontal folding line 53 is folded in a valley. As a result, a laterally bent portion 63 is formed.

  As shown in FIG. 4, the first and third peripheral wall panels 21 and 23 may be bent so that the first and second vertical folding lines 51 and 52 are formed into valley folds. 53 must bend the rear end wall 43 so as to make a mountain fold. Two vertical bent portions 71 and 72 and a horizontal bent portion 73 are formed respectively.

  3 and 4, the first and third peripheral wall panels 21 and 23 and the rear end wall 43 are not shown in a state of being folded in two, but each of the panels 21, 23 and 43 is folded. It is easy to imagine that if you increase the degree of the song.

  After the contents are stored in the paper box shown in FIG. 1, the insertion panel 42 is inserted into the second peripheral wall panel 22 and, for example, the front end wall panel 41 and the insertion panel 42 are inserted between the opposite contents. When bent, the front end openings formed by the first to fourth peripheral wall panels 21 to 24 are closed by the front end wall panel 41, and there is no fear that the front end wall panel 41 is opened carelessly.

  The contents to be accommodated in the paper box are suitable for accommodating one article in a form that fits almost perfectly in the paper box, or a plurality of articles that have almost the same form as the same article when superimposed.

  The material of the paper box does not matter. When storing heavy objects, the quality of paper may be cardboard or the like. In this case, instead of using a seal panel, these may be omitted, and the corresponding portions may be connected by a tape. Further, the paper box may be shrink-wrapped.

  Next, various modifications of the blank and the paper box will be described. In the following description, portions corresponding to the lower portion are denoted by the same reference numerals.

  In the blank shown in FIG. 1, the front end wall panel 41 is connected to the front edge of the fourth peripheral wall panel 24, but instead, in the blank shown in FIG. 5, the front end wall panel 41 is in front of the second peripheral wall panel 22. It is connected to the edge. Otherwise, both blanks have the same configuration. The paper box assembled from the blank shown in FIG. 5 is shown in FIG. The folding method of this paper box is the same as that of the paper box assembled from the blank shown in FIG.

  In the blank shown in FIG. 7, three first to third peripheral wall panels 21 to 23 are sequentially connected from left to right via two first and second vertical bending curves 11 and 12. The first vertical seal panel 25a is connected to the free edge of the first peripheral wall panel 21 via the third vertical bending line 15, and the free edge of the third peripheral wall panel 23 is connected via the fourth vertical bending curve 16. The second vertical seal panel 25b is connected. First and second vertical folding lines 51 and 52 are formed on the first and third peripheral wall panels 21 and 23, respectively. The rear end wall panel 43 is connected to the rear edge of the second peripheral wall panel 22 through the first horizontal folding curve 33, and the horizontal folding line 53 is formed in the same manner as in the above blanks. However, the fourth peripheral wall panel 24 and the front end wall panel 41 are successively connected to the rear edge of the rear end wall panel 43 from the front to the rear via the second and third horizontal bending curves 35 and 36. Further, an insertion panel 42 is connected to a rear edge portion of the front end wall panel 41 via a fourth horizontal folding curve 37.

  The paper box assembled from this blank is shown in FIG. The paper box shown in FIG. 8 is very similar to the paper box shown in FIG. 2, except that the first and second vertical seal panels 25a and 25b are sealed on the inner surface of the fourth peripheral wall panel 24. .

  FIG. 9 shows a blank according to a further variant. As a material of the blank according to this modified example, cardboard is particularly preferably used.

  The state in which the first to third peripheral wall panels 21 to 23 are continuous in the left-right direction and the state in which the second peripheral wall panel 22, the rear end wall panel 43, and the fourth peripheral wall panel 24 are sequentially connected in the front-rear direction are shown in FIG. Is the same as In the blank according to this modification, the first front end wall panel 41a is connected to the front edge of the second peripheral wall panel 22 via the third transverse bending curve 38, and the second front end wall is connected to the rear edge of the fourth peripheral wall panel 24.
