The connection piece 17 is bent along the mountain fold lines 31 to 34 (S311).

Subsequently, an adhesive (hot melt or the like) is applied to the surface of the connecting piece 17, and the surface of the connecting piece 17 is adhered to the back surface of the first side surface plate 11 (S312).

Subsequently, the above-mentioned tubular body is assembled by three-dimensionally raising the blank 5 using a carting machine (box making machine) or the like (S313).

4A and 4B show how the above-mentioned tubular body is assembled.

Subsequently, an container such as tissue paper is packed in a cylinder (S314), and the packaging box 10 is sealed (sealed) (S315). Sealing is performed using, for example, a boxing machine, a sealing device, or the like.

5A and 5B show how the packaging box 10 is sealed. Hereinafter, for the sake of simplicity, the description will be focused on one end face of the tubular body described above, but the same processing is performed on the other end face of the tubular body.

First, the first side surface flap 111a and the second side surface flap 131b are bent along the mountain fold line 41a and the mountain fold line 43a, respectively. Subsequently, the lower surface flap 141a is bent along the mountain fold line 44a so as to overlap the first side surface flap 111a and the second side surface flap 131a. Subsequently, the upper surface flap 121a is bent along the mountain fold line 42a so as to be overlapped on the lower surface flap 141a. At a predetermined stage of each of the above bending steps, an adhesive for adhering the floating upper portion 115a and the floating upper portion 125a, and the floating upper portion 135a and the floating upper portion 126a is spot-applied to a predetermined portion.

After the above procedure, the packaging box 10 reaches the user via a distribution channel or the like. The user peels off the lid 2 to open the packaging box 10 (FIG. 6) (S316) and consumes the contents (S317).

After that, the used packaging box 10 is efficiently disassembled (S318) and discarded (S319) according to the procedure described below.

<Disassembly procedure>
The procedure for disassembling the packaging box 10 will be described with reference to FIGS. 7A to 7D.

First, as shown in FIG. 7A, the user picks up the vicinity of the short side of the lid 2 of the top plate 12 of the packaging box 10 with his fingers and rolls it upward. As a result, the upper surface plate 12 is delaminated by the action of the front side half-cut lines 123a, 123b, 123c, 123d and the back side half-cut lines 124a, 124b, 124c, 124d. More specifically, the delamination zone (first delamination zone) composed of the half-cut line 123a on the front surface side and the half-cut line 124a on the back surface side of the top plate 12, and the half-cut line 123b on the front surface side. Delamination band composed of half-cut wire 124b on the back surface side (second delamination zone), delamination zone composed of half-cut line 123c on the front surface side and half-cut line 124c on the back surface side (first interlayer) The delamination zone) and the delamination zone (second delamination zone) composed of the half-cut line 123d on the front surface side and the half-cut line 124d on the back surface side are delaminated, respectively. As a result, as shown in FIG. 7B, the substantially triangular portion of the upper surface plate 12 having the short side of the upper surface plate 12 as the base is separated from the upper surface plate 12. The delamination action allows the user to smoothly perform the delamination operation. Further, due to the delamination action, the user can cleanly separate the substantially triangular portion from the upper surface plate 12.

Subsequently, as shown in FIG. 7B, the user operates so as to open the separated substantially triangular portion while pinching it with his / her fingers to the side of the packaging box 10. As a result, the end faces of the packaging box 10 (the side surface composed of the upper surface flap 121a, the lower surface flap 141a, the first side surface flap 111a, and the second side surface flap 131a, and the upper surface flap 121b, the lower surface flap 141b, the first side surface flap 111b, The end face composed of the second side surface flap 131b) is delaminated by the action of the front side half-cut lines 113a, 113b, 133a, 133b and the back side half-cut lines 114a, 114b, 134a, 134b. More specifically, the delamination zone (third delamination zone) composed of the half-cut line 113a on the front surface side of the first side surface flap 111a and the half-cut line 114a on the back surface side, and the surface of the first side surface flap 111b. Delamination band (third delamination band) composed of half-cut line 113b on the side and half-cut line 114b on the back side, half-cut line 133a on the front side and half-cut line on the back side of the second side flap 131a. A delamination band composed of 134a (fourth delamination band), and a delamination band composed of a half-cut line 133b on the front surface side and a half-cut line 134b on the back surface side of the second side surface flap 131b (fourth delamination band). Delamination zone), respectively. Then, as shown in FIG. 7C, the end face of the above-mentioned cylinder of the packaging box 10 is separated from the above.

When the user operates the substantially triangular portion while pinching it with his / her finger to open it to the side of the packaging box 10, the cut portion 112a, the cut portion 112b, the cut portion 132a, and the cut portion Since the stress is concentrated on 132b, the delamination (delamination of the third delamination zone and the delamination of the fourth delamination zone) is naturally induced, and the user can separate the end faces of the cylinder smoothly and neatly. it can.

Subsequently, as a result of the above operations, both the first side plate 11 and the second side plate 13 are no longer supported, so that the user only operates to tilt the first side plate 11 and the second side plate 13. The packaging box 10 can be easily unfolded, and the packaging box 10 can be made flat at once as shown in FIG. 7D. As shown in the figure, in this state, the thickness of the unfolded packaging box 10 is about the thickness of one blank. Therefore, for example, when a plurality of disassembled paper pieces of the packaging boxes 10 are stacked, the overall bulkiness is small, the storage and handling are excellent, and the disposal work can be efficiently performed.

The external force applied to the packaging box 10 during the use (consumption) of the contained material, that is, during the use of the packaging box 10, is usually a force from the outside to the inside of the packaging box 10. Therefore, the packaging box 10 will not be disassembled unless the user intentionally performs the above disassembly operation (the operation of pinching the vicinity of the short side of the lid portion with a finger and rolling it upward).

By the way, the above description is for facilitating the understanding of the present invention, and does not limit the present invention. The present invention can be modified and improved without departing from the spirit thereof, and the present invention includes equivalents thereof.

For example, inside the outlet 2a of the packaging box 10, a structure (a slit for passing the disposable paper is formed at a position corresponding to the vicinity of the center of the outlet 2a) that functions as a hook for the subsequent disposable paper when the disposable paper is taken out. The present invention can be applied even when a disposable resin film or the like is provided. For example, most of the resin films that are an example of the above structure are provided by adhering the peripheral edge portion to the periphery of the outlet 2a on the back surface side of the top plate 12, and as shown in FIG. 7A, the resin film is provided. As described above, when the user picks up the vicinity of the short side of the lid 2 of the top plate 12 of the packaging box 10 with a finger and rolls it upward, it naturally peels off from the top plate 12, so that the above structure is used. The present invention can be applied to the packaging box 10 having the same without any problem.
