The crease lines 46 and 48 are formed with kerfs at regular intervals so that they can be easily bent. The front ends of the flaps 42 and 44 are also formed so as to oppose each other or be stacked on each other in a folded state in which a box is formed.

  At the upper end portion of the side surface 16 located between the crease lines 26 and 28, an upper lid piece 50 is provided by being separated by a crease line 52. Grooves are formed in the crease line 52 at regular intervals, and a glued piece 56 that is further glued to the outside of the side surface 20 in an assembled state is provided at the end of the upper lid piece 50 opposite to the crease line 52. 54 are formed integrally. A cut groove is also formed in the crease line 54, and a pair of opening sewing lines 58 that are parallel to the crease line 54 and parallel to the crease line 54 are formed in the glue piece 56. An opening knob 60 is provided at one end between the pair of opening sewing wires 58. The front end side of the unsealing sewing machine wire 58 of the gluing piece 56 is a gluing portion 62 that is glued to the side face 20, and the base end side is an insertion piece 64 that is inserted into the box after opening.

  Between the both ends of the crease lines 52 and 54 of the upper lid piece 50, folded pieces 66 and 68 that are folded and glued inside the upper lid piece 50 are provided from the side edges of the upper lid piece 50 via the crease lines 70 and 72. It is formed to extend.

  A first bottom cover piece 74 is provided at the lower end of the side surface 16 located between the crease lines 26 and 28 and separated by the crease line 76. In the crease line 76, kerfs are formed at regular intervals. On the side edge perpendicular to the crease line 76 of the first bottom lid piece 74, folded pieces 78 and 80 that are folded and glued inside the first bottom lid piece 74 are attached to the upper lid via the crease lines 82 and 84. It extends from the side edge of the piece 50.

  On the side edge of the side surface 20 that is perpendicular to the crease line 30, a second bottom lid piece 86 that is glued to be positioned outside the first bottom lid piece 74 in an assembled state is integrally formed via the crease line 88. Has been. A cut groove is also formed in the crease line 88, and the second bottom cover piece 86 is formed to have a size substantially equal to that of the first bottom cover piece 74. At the center of the second bottom cover piece 86, a pair of two disassembling sewing machine lines 90 parallel to the crease line 88 are formed. An opening knob 92 is provided at one end between the pair of disassembling sewing machine wires 90. Then, the distal end side of the disassembling sewing machine wire 90 of the second bottom lid piece 86 is glued to the first bottom lid piece 74.

  Next, a method for assembling the double bottom lid packaging box 10 of this embodiment will be described. Here, FIG. 1 is a view of the surface of the box-forming piece 12 of the double-bottom lid packaging box 10, the folding method in which the surface of the box-forming piece 12 is convex, and the back side is The method of folding that is convex is called reverse folding.

  First, paste 96 is applied to the back surfaces of the folded pieces 66, 68 of the upper lid piece 50 and the folded pieces 78, 80 of the first bottom lid piece 74, and the folded pieces 66, 68 are normally folded at the folding lines 70, 72. The folded pieces 78 and 80 are normally folded along the crease lines 82 and 84 and glued to the back surfaces of the upper lid piece 50 and the first bottom lid piece 74, respectively. Next, gluing is applied to the surface of the gluing piece 22, the crease line 26 is fold-folded, the crease line 30 is fold-folded, and the edge of the side surface 20 is glued to the gluing piece 22.

  Thereafter, when the contents are put in the box, the crease lines 24, 26, 28, 30 are each normally folded at 90 degrees to form a rectangular box. At this time, the flaps 34 and 44 are normally folded, the first bottom cover piece 74 is normally folded, and the second bottom cover piece 86 is glued to the outside of the first bottom cover piece 74.

  Then, the product is stored in the box, the flaps 32 and 42 are forwardly folded, the upper lid piece 50 is forwardly folded, glued to the back surface of the glued portion 62 of the glued piece 56, and is folded at the folding line 54, The glue piece 56 is glued to the outside of the side surface 20.

  When taking out the product from the double bottom lid packaging box 10 of this embodiment, pulling the grip portion 60 and breaking between the opening sewing wires 58, the upper lid piece 50 is separated from the side surface 20 and opened. After the product is taken out, the upper cover piece 50 can be closed by inserting the insertion piece 64 into the box.

  Further, when dismantling the double bottom lid packaging box 10 that is no longer needed, it is pulled by holding the unsealing knob portion 92 between the disassembling sewing machine wires 90 and the disassembling sewing machine wire 90 with the second bottom cover piece 86. Is broken, the base end portion of the second bottom lid piece 86 can be opened and closed, and the double bottom lid packaging box 10 can be neatly folded.

  According to the double bottom lid packaging box 10 of this embodiment, the structure is simple, and the bottom surface of the box body is covered by the first bottom lid piece 74 and the second bottom lid piece 86, and a gap is formed on the bottom surface of the box body. It is hard to be done. Further, the upper cover piece 50 and the first bottom cover piece 74 are provided with folded pieces 66, 68 and folded pieces 78, 80, and the side edges are reinforced. Is not formed, and extraction and tampering can be reliably prevented, and the safety of the product can be ensured.

  In addition, this invention is not limited to the said embodiment, The shape of a folding piece, a flap, etc. can be changed suitably.

It is an expanded view of the box for double bottom lid packaging of one Embodiment of this invention. It is a perspective view of the state which opened the upper cover piece of the double bottom lid packaging box of this embodiment. It is a perspective view in the state where the 2nd bottom lid piece of the double bottom lid packaging box of this embodiment was opened.
