  It is desirable that this type of packaging box can be disassembled into a flat state so as not to be bulky when discarded after use. However, the packaging box of Patent Document 1 has a problem that it is not easy to disassemble it into a flat state after use. In order to disassemble the packaging box into a flat state, for example, the glued part of the side part formed by gluing a plurality of side flaps is peeled off, or the base part of the side flaps is cut with scissors or a cutter. There is a need. Therefore, it is not always an easy task for small children and the elderly, and it is troublesome for ordinary adults.

  Moreover, it is also conceivable to apply a structure in which a cutting line for dismantling extending from the end of the bottom plate to the side surface like the packaging box of Patent Document 2 is applied to the packaging box of Patent Document 1. However, in the case of the packaging box of Patent Document 1, unlike the packaging box of Patent Document 2, the upper lid piece is disassembled after being used so that it can be opened and closed. The boundary with the flap is already cut off. Therefore, if the above-mentioned dismantling cut line is provided in the packaging box of Patent Document 1 and the dismantling cut line is broken at the time of disassembly, a part of the side surface part becomes separated and independent, and handling at the time of disposal becomes complicated. Problem arises.

  An embodiment of the present invention will be described below with reference to FIGS. The packaging box 10 of this embodiment is formed by assembling a wrap-around type box-forming piece 12 formed by punching out a single paper blank sheet.

  FIG. 4 is a developed view of the box forming piece 12 as seen from the surface. The box forming piece 12 is formed by sequentially connecting a bottom plate 16, a back plate 18, and an upper lid piece 20 in parallel with each other in order from the front plate 14 positioned in front in the assembled state. The front plate 14, the bottom plate 16, the back plate 18, and the upper lid piece 20 are connected to each other in substantially the same width direction, and the length in the connecting direction is substantially equal to each other because the front plate 14 and the back plate 18 are long. The bottom plate 16 and the upper cover piece 20 are short and substantially equal to each other. Furthermore, the insertion piece 22 inserted in the inner side of the front board 14 in the assembly state of the packaging box 10 is provided in the edge of the connection direction of the upper cover piece 20. The front plate 14, the bottom plate 16, the back plate 18, the upper lid piece 20, and the insertion piece 22 are divided by crease lines 24, 26, 28, and 30, respectively.

  The front plate 14 is provided with a semicircular cutout 14 a at the center of the end opposite to the bottom plate 16. A side flap 32 that is a trapezoidal side member is provided on one end side perpendicular to the direction of connection with the bottom plate 16 and separated by a crease line 34. The length from the crease line 34 to the tip of the side flap 32 is slightly shorter than half the length of the bottom plate 16 in the connecting direction. A side surface flap 36 having substantially the same shape as the side surface flap 32 is provided on the end side of the front plate 14 opposite to the crease line 34 and separated by a crease line 38.

  A trapezoidal side surface flap 40 is provided on an end of the bottom plate 16 adjacent to the crease line 34 of the front plate 14, separated by a crease line 42. The length from the crease line 42 to the tip of the side flap 40 is provided approximately half of the length of the front plate 14 in the connecting direction. A side surface flap 44 having substantially the same shape as the side surface flap 40 is provided on the end side opposite to the crease line 42 of the bottom plate 16 and separated by a crease line 46.

  Further, the bottom plate 16 is provided with an arc-shaped break line 48 starting from both ends of the crease line 42, and a pushing portion 50 surrounded by the crease line 42 and the break line 48 is formed. An arc-shaped break line 52 starting from both ends of the crease line 46 is also provided on the crease line 46 side of the bottom plate 16, and a pushing portion 54 surrounded by the crease line 46 and the break line 52 is formed. . Disposal folding lines 56a, 56b, and 56c are provided at the center position in the width direction where the side flap 40, the bottom plate surface 16, and the side flap 44 are continuous.

  A trapezoidal side flap 58 is provided on the end of the back plate 18 adjacent to the crease line 42 of the bottom plate 16, separated by the crease line 60. The side flap 58 has substantially the same shape as the side flap 32. A side flap 62 that is substantially the same shape as the side flap 58 is provided on the end of the back plate 18 opposite to the crease line 60, separated by a crease line 64.

  A trapezoidal side surface flap 66 is provided on an end of the upper lid piece 20 adjacent to the crease line 60 of the back plate 18 and separated by a break line 68. The side flap 66 has substantially the same shape as the side flap 40. A side flap 70 having substantially the same shape as the side flap 66 is provided on the end of the upper lid piece 20 opposite to the break line 68, separated by a break line 72. Further, disposal folding lines 74 and 76 are provided at the center positions of the side flaps 66 and 70 in the width direction.

  Next, an example of an assembly method of the packaging box 10 of this embodiment will be described. Here, FIG. 4 shows the surface of the box-forming piece 12 of the packaging box 10, the folding method in which the surface of the box-forming piece 12 is convex and the folding in which the back surface is convex. This is called reverse folding.

  First, paste 78 is applied to the back surfaces of the side flaps 40, 44, 66, and 70, respectively. Next, the box-forming piece 12 is opened with the back surface facing up, and the commodity 80 as a container is placed side by side at a predetermined position. Here, ten products 80 are divided into two rows of five and arranged without gaps. Then, the crease lines 24, 26, 28, and 30 are normally folded at 90 degrees, and the product 80 is wrapped in a cylindrical shape by the front plate 14, the bottom plate 16, the surface back plate 18, and the upper lid piece 20. At this time, the insertion piece 22 is inserted between the back side of the front plate 14 and the product 80.

  Next, the side flaps 32 and 58 are normally folded at 90 degrees by the crease lines 34 and 60, and the side flaps 40 and 66 are normally folded by 90 degrees by the crease line 42 and the breaking line 68. At this time, the back surface of the side surface flaps 40 and 66 is glued to the surface of the side surface flaps 32 and 58 with the glue 78, and the side surface part 82 which closes one end part is formed. Next, the side flaps 36 and 62 are normally folded at 90 degrees by the crease lines 38 and 64, and the side flaps 44 and 70 are normally folded by 90 degrees by the crease line 46 and the breaking line 72. At this time, the back surfaces of the side surface flaps 44 and 70 are glued to the surfaces of the side surface flaps 36 and 62 with the glue 78 to form a side surface portion 84 that closes the other end portion.

  The packaging box 12 can be assembled by the process as described above. The order of assembling the box forming pieces 12 may be other than this, and can be changed as appropriate.

  When the packaging box 10 of this embodiment is opened, the insertion piece 22 is lifted by placing a finger on the insertion piece 22 exposed from the notch 14 a of the front plate 14. Then, an upward pulling force is applied to the upper lid piece 20, the breaking lines 68 and 72 are broken as shown in FIG. 6, and the upper lid piece 20 can be opened and closed, and the product 80 stored in the container is taken out. It becomes possible.

  Next, a method of disassembling for disposal after using the packaging box 10 of this embodiment will be described with reference to FIGS. First, the upper cover piece 20 of the empty packaging box 10 is opened and placed upside down as shown in FIG. Then, as shown in FIG. 2, the pushing portions 50 and 54 of the bottom plate 16 are pressed with a finger to break the break lines 48 and 52 and bend them inward.

  Next, a force is applied so that the side surfaces 82 and 84 are pulled out while the finger is applied to the bent pressing portions 50 and 54. At this time, it is preferable that the bottom plate 16 is slightly warped so as to be pulled upward. Then, as shown in FIG. 3, the side surface portion 82 is bent at the disposal folding curves 56 a and 74, and the pushing portion 50 is folded at the disposal folding curve 56 b, and is folded into a flat state so that they overlap. Similarly, the side surface portion 84 is bent at the disposal folding lines 56c and 76, and the push-in portion 54 is folded at the disposal folding line 56b, and is folded into a flat state so that they overlap. Further, the bottom plate 16 is folded at the disposal crease line 56b and folded into a flat state. That is, the packaging box 10 is folded into a flat state as a whole.

  At this time, the side flaps 32 and 58 have a short length to the tip, so that they do not overlap each other in the assembled state. Further, since the side flaps 36 and 62 have a short length to the tip, they do not overlap each other in the assembled state. Accordingly, the side surface portions 82 and 84 are bent at portions where the side surface flaps 32 and 58 do not exist, and the side surface flaps 32 and 58 do not hinder the above-described folding operation.

  As described above, the packaging box 10 of this embodiment can be easily disassembled by adding a simple configuration of break lines 48 and 52 for separating the pushing portions 50 and 54 of the bottom plate 16. it can. In particular, since it is not necessary to apply a strong force to peel off the glued portions of the side portions 82 and 84, it can be easily disassembled by children and the elderly, and the end portions of the side portions 82.84 can be removed with scissors and a cutter. There is no need for troublesome operations such as separation. Moreover, since a specific part is not separated and independent when disassembled, it is easy to handle when disposing the packaging box 10 and then disposing it.

  Further, by providing the folding fold lines 56a, 56b, 56c, 74, 76 for assisting folding, the bottom plate 16, the side portions 82, 84 and the pushing pieces 50, 54 can be easily folded. This is effective when using relatively thick materials.

  The packaging box of the present invention is not a wrap-around type, and may be provided with an upper lid piece 20 having a normal top surface and having no side flaps as shown in FIG. For the box-forming piece 86, the same components as those in the above embodiment are described with the same reference numerals. In the assembled state, the bottom plate 16, the back plate 18, and the upper lid piece are sequentially arranged from the front plate 14 located in front. 20 are formed in parallel with each other. An insertion piece 22 to be inserted into the front plate 14 in the assembled state of the packaging box is provided at the end in the connecting direction of the upper lid piece 20. A side flap 32, which is a trapezoidal side member, is provided on one end of the front plate 14 perpendicular to the connecting direction with the bottom plate 16, separated by a crease line 34. The length from the crease line 34 to the tip of the side flap 32 is slightly shorter than half the length of the bottom plate 16 in the connecting direction. A side surface flap 36 having substantially the same shape as that of the side surface flap 32 is also provided on the end of the front plate 14 opposite to the crease line 34, separated by a crease line 38.

  A trapezoidal side flap 58 is also provided on the end of the back plate 18 adjacent to the crease line 42 of the bottom plate 16, separated by the crease line 60. The side flap 58 has substantially the same shape as the side flap 32. A side flap 62 that is substantially the same shape as the side flap 58 is provided on the end of the back plate 18 opposite to the crease line 60, separated by a crease line 64.

  The edge of the bottom plate 16 adjacent to the crease lines 34, 38 of the front plate 14 has sides having the same length as the crease lines 34, 38, and the side in contact with the crease lines 34, 38 is defined as the other side. Square side members 88 and 90 are provided by being separated by crease lines 42 and 46, respectively. On the side opposite to the crease lines 42 and 46 of the side members 88 and 90, substantially trapezoidal flaps 96 and 98 are provided with the crease lines 92 and 94 interposed therebetween.

  Further, the bottom plate 16 is provided with an arc-shaped break line 48 starting from both ends of the crease line 42, and a pushing portion 50 surrounded by the crease line 42 and the break line 48 is formed. An arc-shaped break line 52 starting from both ends of the crease line 46 is also provided on the crease line 46 side of the bottom plate 16, and a pushing portion 54 surrounded by the crease line 46 and the break line 52 is formed. . Disposal folding lines 100a, 100b, 100c, 100d, and 100e are provided in a straight line at the center position in the width direction where the bottom plate surface 16, the side members 88 and 90, and the flaps 96 and 98 are continuous.

  In the assembly of the packaging box of this embodiment, the side flaps 32, 36, 58, 62 and the side members 88, 90 are glued to form a box, as in a general box. And after accommodating goods in an inside, the upper cover piece 20 is closed and the insertion piece 22 is inserted inside the front board 14, and is sealed.

  The packaging box formed by the box forming piece 86 of this embodiment also has the same effects as the packaging box 10 of the above embodiment.

  Note that the packaging box of the present invention is not limited to the above embodiments, and the shape of the break line surrounding the pushing portion of the bottom plate is V-shaped or semi-elliptical as shown in FIG. The shape, such as a curved line or a bent straight line, can be freely changed.

  Further, high-quality cardboard is usually used as the box-forming piece, but cardboard paper or single-cardboard paper may be used. In addition, when it can be folded relatively easily, all or part of the folding folding curve for assisting folding may be omitted.

  Further, for example, when the side flaps of the front plate and the side flaps of the back plate are provided longer and overlap each other in the assembled state, the strength of the side portion of the packaging box is increased. Disassembly work can be facilitated by providing a similar folding curve at a position that is sometimes bent, that is, at a position that overlaps with the folding curve in the above embodiment.
