  However, in the packaging box as described above, since the cut line is along the ridge line of the corner of the peripheral wall, the pressure strength at the time of stacking in the horizontal position may be reduced, and for sticking of the cut tape There is also the problem of high costs.

  Then, this invention makes it a subject to provide the side opening packaging box which is excellent in pressure | voltage resistant strength and can be manufactured at low cost.

  In order to solve the above-mentioned problems, the present invention provides a packaging box in which flaps are respectively extended from one side plate and the other side plate that are adjacent to each other on the peripheral wall, and these flaps are bonded and sealed. A longitudinal cut band is provided between the cut lines, and the flap connected to the side plate is exposed with the push-in part that is the starting end of the cut band, and the flap is spaced from the ridge line with the side plate. Then, a lateral cut row was inserted, and after the cut zone was excised, along with the cutting of the transverse cut row, one side plate was opened around the ridge line with the other side plate.

  Further, instead of the lateral cut row, a lateral cut row having an inclined cut is placed on the ridge between the side plate and the flap provided with the cut strip, and the transverse cut is cut off after cutting the cut strip. The rows were cut so that one side plate was opened with the ridge line with the other side plate as an axis.

  Furthermore, the pushing part used as the starting end of a tear band was provided in the inner side flap among the overlapping flaps, and was exposed from the notch part formed in the outer side flap.

  In this side opening packaging box, there is no vertical cut line at the ridge part of the adjacent side plate, and the horizontal cut line is shifted from the ridge line with the side plate to the flap connected to the side plate provided with the tear band. Alternatively, since a lateral cut row with inclined cuts is provided at the ridge portion between the side plate and the flap provided with the cut band, a decrease in pressure strength at the time of stacking in the horizontal state is prevented.

  Further, these lateral cut lines do not affect functions such as opening even if the position is slightly shifted, and it is not necessary to attach a cut tape, so that they can be manufactured at low cost.

  First, a first embodiment of the present invention will be described with reference to FIGS.

  This packaging box is made of cardboard for packaging beverage-containing plastic bottles. As shown in FIG. 1, in this packaging box blank, a pair of narrow and wide side plates 1 and 2 are alternately connected to each other, and a passage piece 3 is continuously provided outside the side plate 2 at one end. ing. An inner flap 4 and an outer flap 5 are connected to the upper and lower ends of the side plates 1 and 2, respectively.

  The side plate 1 is provided with a longitudinal cut band 7 sandwiched between two zipper-shaped cut rows 6 in which the saddle-shaped cuts are interrupted, and the pushing portion 8 at the start thereof reaches the upper inner flap 4. The end reaches the lower inner flap 4. At the corner of the upper outer flap 5, a notch 9 that exposes the pushing portion 8 is formed.

  In addition, the upper and lower inner flaps 4 are provided with a horizontal cut row 10 extending from both sides of the side plate 1 at a distance from the ridge line with the side plate 1. It is a zipper shape.

  When using the packaging box made of the blank, as shown in FIG. 2, the side plates 1 and 2 are bent into a square tube shape, and the passage piece 3 is attached to the inner surface of the opposite side plate 1 After the lower inner flap 4 and the outer flap 5 are bonded together and the bottom surface is closed and the PET bottle is stored in the box, the upper inner flap 4 and the outer flap 5 are bonded together and sealed.

  On the other hand, when filling a plastic bottle into a vending machine, in order to take out the plastic bottle in a state in which the packaging box is placed vertically, as shown in FIG. 3, as shown in FIG. The side plate 1 facing upward is divided by pushing the pushing portion 8 and inserting a finger into the extraction hole and pulling the cut band 7 for excision. Thus, when the pushing part 8 is exposed from the notch part 9, the torn zone 7 can be easily excised.

  Thereafter, as shown in FIG. 4, when the side plate 1 is opened to the left and right with the ridge line with the adjacent side plate 2 as an axis along with the cutting of the cut line 10 in the lateral direction, the side surface facing upward is entirely covered. Therefore, the plastic bottle B can be taken out and filled in a vending machine.

  In the packaging box as described above, there is no vertical cut line at the ridges of the adjacent side plates 1 and 2, and the horizontal cut line 10 is put at a position shifted from the ridge line with the side plate 1 of the inner flap 4. Therefore, it is possible to prevent a decrease in pressure strength when stacked in a horizontal state.

  In addition, since these lateral cut lines 10 do not affect functions such as opening even if they are slightly displaced, they can be easily manufactured by flexo-glue, and no sticking of cut tape is required. Can be suppressed.

  Next, a second embodiment of the present invention will be described with reference to FIGS.

  This packaging box has the same basic configuration as that of the packaging box according to the first embodiment. Instead of the horizontal cut row 10, the ridges of the inner flap 4 and the side plate 1 are arranged on the ridgeline. The only difference is that a horizontal row of cuts 11 in which the cuts are inclined and interrupted so as to intersect is inserted.

  Even if such a horizontal cut row 11 is inserted, a decrease in the pressure strength at the time of stacking in the horizontal state is prevented as in the packaging box of the first embodiment, and the position of the cut row 11 is Even if it is slightly deviated, it does not affect functions such as openability, it can be easily manufactured with flexogluer, and it is not necessary to stick a cut tape, so the cost can be suppressed.

  In each of the above embodiments, the side plates 1 at both ends of the packaging box can be opened, but only one side plate 1 may be opened.

  Further, instead of the side plate 1 and the inner flap 4, the side plate 2 and the outer flap 5 are provided with the tear band 7 and the pushing portion 8, respectively, and the outer flap 5 is provided with the cut row 10, or the side plate 2 and the outer flap The cut line 11 may be inserted at the ridge with 5.

  In addition to the rectangular parallelepiped packaging box exemplified in each of the above embodiments, the same configuration can be applied to an irregular packaging box whose peripheral wall forms a hexagonal cylinder shape, an octagonal cylinder shape, etc. Can be applied.
