Are provided with tongues 8a and 9a that can be inserted into the slits α and β, respectively.

  The movable pieces 5a and 5b defined in the top surface inner panel 5 are exposed from the opening 4a of the top surface panel 4 when assembled, and each of them can be opened by turning the folding lines a and b as hinges. It is like that. These folding lines a and b are constituted by so-called lead rules provided with cuts at several points in the middle of the ruled line, and are easy to bend. Moreover, the knob part 5c protrudes and is formed in one movable piece 5a by the semicircle-shaped cut formed in the boundary part.

  Fan-shaped gear panels 10a and 10b connected to one side of the pair of movable pieces 5a and 5b are punched and formed on one side intermediate panel 10, and a pair of movable pieces is formed on the other side intermediate panel 11. Fan-shaped gear panels 11a and 11b are formed by punching so as to be connected to the other side of the pieces 5a and 5b. In other words, gear panels 10a and 11a are connected to both sides of one movable piece 5a via a broken line on one side, and gear panels 10b and 11b are arranged on one side on both sides of the other movable piece 5b. It is connected to the side through a broken line. And the waveform is formed in each arcuate tip part of gear panel 10a, 10b in one side intermediate panel 10, and these waveforms are when gear panel 10a, 10b rotates centering on the tip of fold lines a and b. Similarly, the arcuate tip portions of the gear panels 10a and 10b in the other side surface intermediate panel 10 are respectively formed with corrugations, and these corrugations are such that the gear panels 10a and 10b are broken lines a. , B are engaged with each other when rotated about the tip.

  In order to assemble the above blank, first, the sack is applied. Specifically, as shown in FIG. 3, the top surface inner panel 5 is folded with respect to the rear panel 3, and paste G is applied to the illustrated position on the front side of the top surface inner panel 5. 2, the front panel 2 and the top panel 4 are folded together with respect to the bottom panel 1, and the top panel 4 is bonded to the top panel 5.

  Then, in the filling step, the sack-attached blank is raised in a square tube shape, one of the body parts is closed, the contents are charged and then the other is closed, so that the entire box shown in FIG. 1 has a rectangular parallelepiped shape. Assemble. The closing order is the same in both cases, and the following description will be made on the left side of FIG. First, the flap panels 12 and 14 are folded, and the side inner panel 6 is folded from above. Next, the side surface outer panel 8 is bent together with the side surface intermediate panel 10, and the tongue piece 8a at the tip thereof is inserted into the slit α and fixed. Similarly, on the right side, first, the flap panels 13 and 15 are folded, the side inner panel 7 is folded from above, the side outer panel 9 is folded together with the side intermediate panel 11, and the tongue piece 9a at the tip is inserted into the slit β. Fix it.

As for the appearance of the packaging box assembled in this way, the top panel 4 is provided with a rectangular opening 4a having two sides opposite to the side surface, and a pair of doors that open in a double-fold manner so as to jump out from the opening 4a. Movable pieces 5a and 5b are provided, and one movable piece 5a is provided with a knob portion 5c for opening at the tip. Then, Giapaneru 10a that continuously provided on both sides of the movable piece 5a, 11a and the other Giapaneru 11a that continuously provided on both sides of the movable piece 5b, 11b is in a state of being incorporated in the side surface.

  In order to open the packaging box of FIG. 1, the knob portion 5c is grasped with a fingertip, and one movable piece 5a is rotated with the fold line a as a hinge. Then, the waveform of the arcuate tip portion of the gear panels 10a and 11a connected to both sides of the one movable piece 5a becomes the waveform of the arcuate tip portion of the gear panels 10b and 11b connected to the other movable piece 5b. The other movable piece 5b is interlocked with the operation of opening and closing the one movable piece 5a by this engagement, and rotates at the folding line b as a hinge.
