  This short flap packaging box collects and wraps large-capacity PET bottles containing beverages, and is formed from a cardboard blank shown in FIG.

  In this blank, the wall plate 2 serving as one side surface and the wall plate 3 serving as the top surface are successively connected to one side of the wall plate 1 serving as the bottom surface so that the tops of the center of the corrugated cardboard extend. The wall plate 2 and the passage piece 4 serving as the other side surface are sequentially provided on the other side of the wall plate 1. Inner flaps 6 are connected to both ends of the wall plate 2 serving as both side surfaces, and outer flaps 5 and 7 are connected to both ends of the wall plates 1 and 3 serving as the bottom surface and the top surface.

  A chamfered portion 8 is interposed between each wall plate 2 and the inner flap 6, and the four corners of the wall plates 1 and 3 are inclined sides corresponding to the chamfered portion 8. The first ruled line 21 that forms the boundary between the one wall plate 2 and the passage piece 4 and the fourth ruled line 22 that forms the boundary between the other wall plate 2 and the wall plate 3 are buckled by the load on the wall plate 2. In order to prevent the deformation, each is bent slightly in a V shape so that the center enters the wall plate 2.

  On the outer flap 7, a pushing piece 10 for transportation is formed between two cut lines 9 inserted from the front edge. Two parallel folding lines 11 are placed in the width direction at the base of the pushing piece 10, and a folding line 12 is placed in the width direction between the leading end of the pushing piece 10 and the folding line 11. It has been.

  The cut line 9 is curved so that the inner part is wound inward to prevent the outer flap 7 from tearing, and is connected to the tip side and the intermediate part of the pushing piece 10 in order to prevent the pushing piece 10 from rolling up during packaging. The part is provided.

  The folding line 11 is a ruled line in which the corrugated cardboard is pressed from the back surface so that it is easy to push the pushing piece 10 in a mountain fold when grasping, and the folding line 12 is a ruled line so that it is easily bent in the valley folding direction when grasping. It is assumed that a cut is made in the middle part.

  The dimensional relationship regarding the pushing piece 10 will be described in detail. As shown in FIG. 2, the ridge line is longer than ½ of the length a from the ridge line 13 that forms the boundary between the wall plate 3 and the outer flap 7 to the tip of the pushing piece 10. The length b from 13 to the folding line 11 close thereto is smaller, and the length c from the other folding line 11 to the folding line 12 is smaller than the length b by about the thickness of the cardboard. .

  As shown in FIG. 1, the inner flap 6 is formed with a notch 14 having a shape corresponding to the end of the pushing piece 10 in a portion overlapping the back side of the pushing piece 10 in the packaged state.

  Further, the wall plate 3 is provided with a pushing portion 15 surrounded by an arc-shaped cut line and a crease line passed between the wall plate 2 and the outer flap 7 from both ends of the pushing portion 15. A cut line 16 that extends obliquely toward the end portion along the ridge line 13 is formed. The slanted portion of the cut line 16 is a zipper type in which Y-shaped cuts are intermittent and have a function to prevent breakage, and the portion along the ridge line 13 is a normal perforation.

  In addition, a cut tape is attached to the rear surface of the corrugated cardboard as a tear strip 17 for opening on the wall plate 2 and the chamfered portions 8 and the inner flaps 6 at both ends thereof. The part 18 is formed with an H-shaped cut line.

  In order to assemble and wrap the PET bottles by assembling the blanks as described above, as shown in FIG. 3, the PET bottles B accumulated on the wall plate 1 are placed, the wall plates 2 on both sides are erected, and the passage pieces 4 Is bent inward and horizontally so that the wall plate 3 is covered with the PET bottle B, and the wall plate 3 and the passage piece 4 are bonded together.

  Then, the chamfered portion 8 is bent obliquely inward along the outer periphery of the PET bottle B, the inner flap 6 is bent inward from the opposing wall plate 2, the outer flap 5 is bent upward, and a pair of inner flaps are formed. 6, the outer flap 7 is bent downward, and is bonded to the upper outer surface of the pair of inner flaps 6. In this packaging state, an opening 19 surrounded by the front edges of the pair of inner flaps 6, outer flaps 5, and outer flaps 7 is formed on the end surface.

  When transporting the short flap packaging box in such a packaging state, the pushing piece 10 is pushed inward along the folding line 11 as shown in FIGS. Accordingly, a care recess 20 that communicates with the opening 19 on the end surface is formed at the trace where the pushing piece 10 is pulled out.

  And the part between the folding line 11 and the folding line 12 of the pushing piece 10 overlaps with the back surface of the outer flap 7 above the folding line 11, and the pushing piece 10 bends along the folding line 12 in the valley folding direction. A portion between the 10 folding lines 12 and the leading edge overlaps the back surface of the end portion of the wall plate 3.

  In the short flap packaging box as described above, when the pushing piece 10 is pushed in, the manual recess 20 formed in the trace where the pushing piece 10 is pulled out is the leading edge of the inner flap 6, the outer flap 5 and the outer flap 7. Since it communicates with the opening portion 19 on the end surface surrounded by, it is easy to put a hand into the care recess 20 during transportation and can be easily gripped.

  And since the pushing piece 10 bends with the folding line 11 and the folding line 12, and hold | grips the rounded bending part in the folding line 11, the cutting edge of a corrugated cardboard does not hit directly and the packaged article | item Even if it is heavy, it becomes difficult to feel pain in the hand.

  Moreover, since the pushing piece 10 overlaps with the outer flap 7 and the back surface of the wall plate 3 and the corrugated cardboard has a double structure at the grip portion, the outer flap 7 becomes difficult to break during transportation, and the quality of the packaging is maintained, The PET bottle B can be delivered to the delivery destination.

  Thereafter, when the delivered short flap packaging box is opened, as shown in FIG. 6, the pushing portion 15 of the wall plate 3 is pushed in and pulled up, the cut line 16 is cut from the pushing portion 15, and the wall plate 3 By opening the portion connected to the passage piece 4 and opening the top surface, the necessary number of PET bottles B can be taken out, and when the remaining PET bottles B are stored, the wall plate 3 Can be closed.

  On the other hand, when the PET bottle B is displayed at the store and sold one by one, as shown in FIG. 7, the tear strip 17 is pulled from the cut-out portion 18, and the wall plate 2, the chamfered portion 8 and the inner flap are pulled. By cutting 6 and removing the upper part from the tear band 17, the PET bottle B can be exposed from the remaining tray part so that it can be taken out freely.

  In the above embodiment, the short flap packaging box having the chamfered portion 8 is exemplified. However, even in a rectangular parallelepiped short flap packaging box without the chamfered portion 8, the gripping portion has the same configuration. Can do.
