  The length of the flexible film 30 in the circumferential direction is designed to be the same as or slightly larger than the outer circumference of the elevating plate 20 in the short direction so that the elevating plate 20 can be accommodated. The flexible film 30 has flexibility and can be expanded and contracted, and the elevating plate 20 can be bent along the crease line h, so that the flexible film is formed from the outer periphery of the elevating plate 20 in the short direction. 30 can also be designed slightly smaller. That is, the circumferential length of the flexible film 30 can be appropriately selected depending on the size of the packaging object K to be accommodated and the degree of expansion / contraction of the flexible film 30.

  The flexible film 30 corresponds to the “flexible cylindrical member” of the present invention.

  Next, a procedure for storing the packaging object K in the exterior box 10 will be described.

  First, the elevating plate 20 is folded into a valley fold along the crease line h and inserted into the flexible film 30.

Next, the knobs 24 raised from the turn-up part 23 are inserted into the notches 140 of the canopy flaps 121, respectively. Then, the neck 24a of the knob 24 is passed between the two locking claws 143 while forcibly bending, and is fitted into the locking hole 142. The width of the neck 24a is smaller than the width of the locking hole 142. And since the width | variety of the head 24b is large, the knob | pick part 24 is latched by the notch part 140 by this. This completes the attachment of the lifting plate 20 to the outer box 10.

  Next, as shown in FIG. 4A, the packaging object K is placed between the placing portion 21 of the lifting plate 20 and the flexible film 30 in a state where the lifting plate 20 is folded in a valley fold along the crease line h. Insert.

Are adjacent to each other, the rising portion 22 of the elevating plate 20 is also erected by the crease line e.

  By the way, in the elevating plate 20, as shown in FIGS. 3 and 4A, the fold line h that has been bent first and the fold line e to be bent next intersect, so that both cannot be bent at the same time. . Therefore, if the crease line e is forcibly folded, the crease line h that has been folded first is automatically restored to the original unfolded state, and the placement portion 21 is brought to the tension of the flexible film 30. Resist to flat plate. As a result, the flexible film 30 is pulled and tensioned to the upper and lower end edges of the placement portion 21 and presses the packaging object K against the placement portion 21, so that the packaging object K is fixed at a predetermined position. .

  Thereby, as shown in FIG. 4A, the packaging object K is inserted between the mounting portion 21 of the elevating plate 20 and the flexible film 30, as shown in FIG. 4B and FIG. 5B can be obtained while the state of FIG. 1B is omitted by bending the upright portion 22 above the mounting portion 21.

  Next, as shown in FIGS. 4C and 5C, the tip of the in-canopy flap 121 is abutted and bent until it becomes horizontal. Then, since each in-canopy flap 121 and the lifting plate 20 are engaged, the lifting plate 20 is bent with respect to the placement portion 21 through the crease line e until the standing portion 22 has an acute angle. The mounting portion 21 is moved toward the bottom portion 13 of the outer box 10.

  At this time, since the length in the height direction of the upright portion 22 is smaller than the height of the trunk portion 11 of the outer box 10, the lifting plate 20 is suspended from the bottom 13 of the outer box 10.

  Finally, by closing both outer canopy flaps 122, the packaging object K is accommodated in the exterior box 10 as shown in FIG. 1A.

  Next, an operation of taking out the packaging object K stored in the exterior box 10 will be described.

  Next, as shown in FIG. 1B, each gripped portion 24 is pulled obliquely upward (in a direction away from each other as it goes upward), and the placement portion 21 is lifted upward.

  At this time, since each knob 24 is engaged with each canopy flap 121, as shown in FIGS. 1B and 5A, the canopy flap 121 is rotated about the crease line c as a rotation axis to expand. Then, the elevating plate 20 is deformed into a flat plate shape.

  Next, as shown in FIG. 4A, the elevating plate 20 is folded into a valley fold along the crease line h. As a result, the flexible film 30 is pulled and released from the tensioned state by being pulled toward the upper and lower end edges of the placement portion 21, so that the packaging object K is placed between the flexible film 30 and the placement portion 21. It can be taken out.

  As described above, according to the packaging box 1 of the present invention, since the knob portion 24 that is a part of the lifting plate 20 is pulled, the lifting plate 20 can be reliably pulled up and locked to the knob portion 24. Since the canopy flaps 121 are also opened, the spread of the canopy flaps 121 can be reliably linked to the rising of the lift plate 20 stored.

  In the packaging box 1 of the present invention, the outer box 10 and the lifting plate 20 are simply fitted and locked to each other, so that they can be easily disassembled and discarded.

  According to the packaging box 1 of the present invention, the packaging object K can be fixed to the placement portion 21 by the flexible film 30, so that the horizontal cushioning can be enhanced. Furthermore, from the state where the packaging object K is inserted into the gap between the flexible film 30 and the placement portion 21, the canopy flap 121 can be fixed on the placement portion 21 simply by folding.

  Further, according to the packaging box 1 of the present invention, in the housed state, the elevating plate 20 is hung on the both canopy flaps 121, and the placing portion 21 is separated from the bottom portion 13 of the outer box 10. The direction buffering can be increased.

  Moreover, in the packaging box 1 of this invention, the folding | turning part 23 and the knob | pick part 24 are extended from the front-end edge of the standing part 22 of the raising / lowering board 20. FIG. As a result, as shown in FIGS. 5A to 5C, the front surface and the back surface of the both canopy flaps 121 are sandwiched between the knob 24 and the folded portion 23, thereby further improving the vertical cushioning. it can.
