Next, the opening process of the packaging box 1 will be described with reference to FIG. FIG. 9 is a perspective view showing a state in which the packaging box 1 is opened.

First, the user picks the front end portion (see FIG. 1) of the opening portion 23 formed on the front side wall 12 (the side wall 12 to which the joint piece 13 is adhered) and pulls it upward. Then, the opening portion 23 is cut along the pair of zippers 21 and the bottom angle cutting line 22 and is separated from the outer box 2. A part of the joint piece 13 corresponding to the opening portion 23 is cut along the pair of joint cutting lines 24.

As described above, the opening 23A that exposes the contents M arranged on each mounting portion 30 and the partition portion 31 is formed. That is, the packaging box 1 is in an opened state.

[Transformation of packaging box (exhibition of contents)]
Next, the deformation process of the packaging box 1 will be described with reference to FIGS. 10 and 11. FIG. 10 is a perspective view showing a state in which the packaging box 1 is deformed into an upright posture. FIG. 11 is a perspective view showing a state in which the packaging box 1 is bent along the bottom folding curve 20 from below.

The opened packaging box 1 has a function of being folded in half and transformed into an upright posture in order to display (display) the contents M.

For example, the user picks up the partition portion 31 (see FIG. 9) exposed to the opening 23A with one hand and pulls it up. The partition portion 31 has a function of partitioning the pair of mounting portions 30 to suppress the movement of the contents M, and a function of a picking portion picked by the user in the deformation process.

As shown in FIG. 10, when the partition portion 31 is pulled up, the pair of mounting portions 30 bends along the partition fold curve 40 due to its own weight and the weight of the content M. Further, the outer box 2 (bottom wall 10) is bent together with the pair of mounting portions 30 so that the opening 23A faces the front side. At this time, the bottom wall 10 bends along the bottom folding curve 20 (see FIG. 11).

As the partition portion 31 is pulled up, the left and right sides of the pair of mounting portions 30 and the outer box 2 hang down relatively. The pair of mounting portions 30 and the outer box 2 are deformed in a posture (standing posture) inclined upward from the outer end portion in the left-right direction (connecting direction) toward the partition portion 31, and stand on their own in this posture. That is, the packaging box 1 becomes a substantially A-shaped form when viewed from the front and stands on its own.

With the above, the deformation of the packaging box 1 is completed. In this state, each of the two-folded outer boxes 2 is formed in a pocket shape (bag shape) with an upper opening. Further, the two-folded inner tray 3 is provided so as to straddle the two-folded outer box 2 (two pockets). Since the inner tray 3 is fixed to the outer box 2 at both left and right ends, it is prevented from coming out of the outer box 2. Then, each content M is leaned against the mounting portion 30 in a state of being inserted into the outer box 2 folded in half. That is, the packaging box 1 serves as a stand for displaying (displaying) the contents M in a leaning state.

As shown in FIG. 11, since the bottom fold curve 20 is formed in a substantially wavy line, when the bottom wall 10 is bent along the bottom fold curve 20, adjacent wave peaks intersect to form the outer box 2. It gets into the inside slightly. As a result, it is possible to make it difficult to return to the original state by intersecting the mountain portions of the waves, and it is possible to keep the bottom wall 10 in a bent state.

In the packaging box 1 according to the present embodiment described above, by pulling up the partition portion 31, the pair of mounting portions 30 are bent along the partition folding curve 40 and are self-supporting in an upright posture.

It was configured to be fixed to the box 2 (see FIG. 7). According to this configuration, the inner tray 3 can be easily fixed to the outer box 2 without using an adhesive or the like. Further, since the movement of the inner tray 3 in the outer box 2 is restricted, damage to the contents M can be suppressed.

Further, in the packaging box 1 according to the present embodiment, the partition portion 31 regulates the movement of the content M in the left-right direction, and the cut-out piece 34 and the receiving piece 33 regulate the movement of the content M in the front-rear direction. And said. Further, the pair of partition walls 31A is configured to protrude toward the end side of the content M (see FIG. 8). According to this configuration, since the content M that is about to rise from the mounting portion 30 comes into contact with the partition portion 31, it is possible to regulate the lifting (movement in the vertical direction) of the content M. As a result, damage to the content M can be effectively suppressed.

Further, according to the packaging box 1 according to the present embodiment, the content M on the mounting portion 30 is sandwiched between the cut-and-raised piece 34 and the upper surface of the mounting portion 30 (see FIG. 5). The positioning of the M can be easily performed, and the misalignment of the content M can be suppressed.
