Are to be connected.

  First, the individual packaging box 100 is formed in a rectangular parallelepiped shape having, for example, a width dimension of 316 mm, a depth dimension of 217 mm, and a height dimension of 343 mm. From the front part 110, the back part 130, the right side part 120, and the left side part 140 of the individual packaging box 100, as shown in FIGS. 1 and 5, first to fourth upper flaps 711 constituting the upper part 150, First to fourth lower flaps 712, 722, 732, and 742 for constituting 721, 731, 741 and the bottom surface portion 160 are extended.

  The individual packaging box 100 is assembled after cutting out one cardboard sheet as shown in FIG. In the present specification, the corrugated cardboard sheet cut out as shown in FIG.

The initial corrugated cardboard sheet 700 includes a front piece 710 that becomes the front part 110 of the individual packaging box 100, a right side piece 720 that becomes the right side part 120, a back piece 730 that becomes the back part 130, and a left side 740 that becomes the left side part 140. It is in the state connected to.
In addition, the corrugated cardboard in this specification is a concept including not only those made of paper but also those made of synthetic resin.

  A first upper flap 711 constituting a part of the upper surface part 150 is formed from the upper edge of the front piece 710, and a second part constituting the part of the upper surface part 150 is formed from the upper edge of the right side piece 720. The upper flap 721 forms a part of the upper surface 150 from the upper edge of the back piece 730, and the third upper flap 731 forms a part of the upper surface 150 from the upper edge of the left side piece 740. Fourth upper flaps 741 are respectively extended.

  Further, a first lower flap 712 constituting a part of the bottom surface part 160 is formed from the lower edge of the front piece 710, and a second part constituting the part of the bottom surface part 160 is formed from the lower edge of the right side piece 720. The lower flap 722 forms a part of the bottom surface 160 from the lower edge of the back piece 730, and the third lower flap 732 forms a part of the bottom 160 from the lower edge of the left side piece 740. Fourth lower flaps 742 are respectively extended.

  In addition, the mountain fold line is formed in the part which connects each vertical piece 771, 772, 773 so that the assembly to the individual packaging box 100 may become easy.

  A connecting flap 750 for connecting to the left side piece 740 protrudes from the side 710A of the front piece 710, that is, from the lower side of the left edge. The initial corrugated sheet 700 is assembled into a rectangular tube by gluing the connecting flap 750 to the inner surface of the left side piece 740.

  The front piece 710 and the back piece 730 have a width dimension of 316 mm and a height dimension of 343 mm, and the right side piece 720 and the left side piece 740 have a width dimension of 217 mm and a height dimension of 343 mm. Therefore, in the state assembled as the individual packaging box 100, the upper surface portion 150 and the bottom surface portion 160 have a width dimension of 316 mm and a depth dimension of 217 mm.

The first upper flap 711 extending from the upper edge of the front piece 710 is formed in a rectangular shape having a width dimension of 316 mm and a depth dimension of 109 mm.
The second upper flap 721 extending from the upper edge of the right side piece 720 has a width dimension of 217 mm and a height dimension of 109 mm, and the upper left corner is notched like the right half of R.

The third upper flap 731 extending from the upper edge of the back piece 730 has a shape in which the width dimension is 316 mm and the depth dimension is 109 mm, and the side adjacent to the right side piece 720 is cut out at right angles to the isosceles side. It has become.
The fourth upper flap 741 extending from the upper edge of the left side piece 740 is formed in a rectangular shape having a width dimension of 215 mm and a depth dimension of 109 mm.

  The reason why the second upper flap 721 and the third upper flap 731 are partially cut away is to facilitate opening and closing of the upper surface portion 150.

On the other hand, the first lower flap 712 extending from the lower edge of the front piece 710 is formed in a substantially M shape by being cut. Before the cut is made, it has a rectangular shape with a width dimension of 316 mm and a depth dimension of 109 mm.

Are formed with box-side slits 761, 762, and 763, respectively.
Each box-side slit 761, 762, 763 is formed from the upper edge of each vertical side 771, 772, 773. Each box-side slit 761, 762, 763 is set to a length of 1/3 of the dimension of each vertical side 771, 772, 773.

  Further, since the connection flap 750 is formed in the lower 2/3 of the side 710A on the left side piece 740 side of the front piece 710, the front piece 710 and the left side face are formed using the connection flap 750. If the piece 740 is connected, the portion without the connecting flap 750 is formed in the same manner as the box-side slits 761, 762, 763.

  In addition, the shape of each upper flap 711,721,731,741 and lower flap 712,722,732,742 is not limited to what was mentioned above, It can be made into various shapes.

The initial corrugated cardboard sheet 700 configured as described above is assembled into the individual packaging box 100 as follows.
First, each vertical side 771, 772, 773 is folded in a mountain, and an adhesive is applied to the surface of the connecting flap 750. Then, the connecting flap 750 is glued to the back surface of the left side piece 740. Thus, the initial corrugated cardboard sheet 700 has a rectangular tube shape.
Next, the first to fourth lower flaps 712, 722, 732, 742 are folded inward to combine them. Thereby, the bottom face part 160 is completed.

If it is set as the individual packaging box 100, the first to fourth upper flaps 711, 721, 731 and 741 are folded inward, but if folded, the individual packaging box 100 is connected by the connecting piece 200. Therefore, the state in this state, that is, the state in which the upper surface portion 150 is opened is held once.
In this state, the vertical side 774 and the box-side slit 764 are formed in the portion where the connecting flap 750 is provided, that is, the portion where the front portion 110 and the left side portion 140 intersect. .

The first to fourth lower flaps 712, 722, 732, and 742 are combined as shown in FIG.
First, the first lower flap 712 and the third lower flap 732 are folded. Thereafter, the second lower wrap 722 and the fourth lower flap 742 are pushed in. Then, the projecting tip portions of the second lower flap 722 and the fourth lower flap 742 naturally enter the M-shaped cut portions of the first lower flap 712 and the third lower flap 732, and are closed. Part 160.

Meanwhile, the connecting piece 200 includes a pair of first sides 210T and 210U having a dimension larger than the diagonal dimension of the individual packaging box 100, and a pair of first sides having a dimension H2 equal to the height dimension H1 of the individual packaging box 100. The lower first side 210U that is in contact with the inner side of the bottom surface 160 when it is housed in the individual packaging box 100 out of the pair of first sides 210T and 210U. A connecting one-side slit 230 is formed from the upper side toward the upper side. The connection piece side slit 230 is formed at a location where the dimension DL2 from the starting point 211U of the lower first side 210U is equal to the diagonal dimension DL.
Note that the portion from the connecting side slit 230 to the second side 220R on the tip side is referred to as an extra piece 240.
Further, a slit-side folding curve 230T is formed from the end of the connecting piece-side slit 230 toward the first side 210T. The slit side folding curve 230T is formed in advance so that it can be bent smoothly when the connecting piece side slit 230 is fitted in the box side slits 761, 762, 763, 764. The slit side folding curve 230T may be formed by perforations so that the folding is smooth.
Further, an auxiliary folding curve 250 is formed in parallel to the slit-side folding curve 230T and on the opposite side of the margin 240 from the slit-side folding piece 230T. The dimension between the auxiliary folding curve 250 and the slit-side folding curve 230T is set equal to the width dimension of the right side piece 720 and the left side part 140 of the individual packaging box 100. The auxiliary folding line 250 is formed in advance so that it can be bent smoothly when the connecting piece 200 is used as an auxiliary connecting piece 600 described later.

Since the height dimension H2 of the connecting piece 200 is equal to the height dimension H1 of the individual packaging box 100, the connecting piece 200 receives a force applied in the vertical direction of the individual packaging box 100. Therefore, it is stronger in the vertical direction than the individual packaging box 100 where the connecting piece 200 does not exist. When this is used as a bed, the connecting piece 200 can receive the weight of the user, so that there is an advantage that the bed can be made strong while being lightweight.
In addition, although the connection piece 200 was arrange | positioned at the diagonal of the individual packaging box 100, and connected the individual packaging boxes 100, X-shaped X-type connection piece (illustration omitted) was used instead of this connection piece 200. Needless to say. This X-shaped connecting piece also has an advantage of further improving the strength of the individual packaging box 100.
