  Next, an example of a method for assembling the packaging box 10 with a buffer function will be described. Here, FIGS. 3 to 5 are views of the back surface of the box-forming piece 12. Hereinafter, the folding method in which the front surface of the box-forming piece 12 is convex and the folding method in which the back surface is convex are described below. Is called reverse folding.

  First, as shown in FIG. 3, the glue 94 is applied to the back surface of the second glued plate 70 and the glue 96 is applied to the back surface of the glued piece 82, and the first creased line 72 is aligned as shown in FIG. Fold it. Thereby, the back surface of the second glued plate 70 is glued to the back surface of the second side plate 18, and the back surface of the glued piece 82 is glued to the back surface of the bottom plate 20. Next, as shown in FIG. 4, glue 98 is applied to the surface of the first glued plate 66, and the crease line 24 is normally folded as shown in FIG. As a result, the back surface of the first side plate 14 is glued to the surface of the first glued plate 66. Thus, the box-forming piece 12 is in a folded state and is shipped in this state.

  Next, in a factory or the like for storing and packaging the contents W, the crease lines 22 and 26 are each normally folded at 90 degrees to form a rectangular box. Then, as shown in FIG. 6, the first side plate 14, the top plate 16, the second side plate 18, and the bottom plate 20 form an outer cylindrical body S1 having a rectangular cross section. At this time, since the surface of the first glued plate 66 is glued to the back surface of the first side plate 14 on the inner side of the outer cylindrical body S1, the second crease line 74 is normally folded and the second glued Since the back surface of the plate 70 is glued to the back surface of the second side plate 18, the fifth fold ruled line 92 is reversely folded, and the L-shaped portion composed of the upper support portion 76 and the connecting portion 78 is located on the bottom plate 20. It is held almost horizontally at an intermediate position with the face plate 16. Further, since the back surface of the glued piece 82 is glued to the back surface of the bottom plate 20, the third fold ruled line 84 is forward-folded, the fourth fold ruled line 86 is reverse-folded, and the side support 80 is the first. It faces the glued plate 66 with a gap. The distance between the side support portion 80 and the first glued plate 66 is slightly longer than the diameter of the trunk portion W1 of the stored article W. Thus, as shown in FIG. 1 and FIG. An accommodation portion S2 surrounded by the coupling portion 78, the side support portion 80, the bottom plate 20 and the first glued plate 66 is formed.

  Next, the crease lines 30, 52 are each normally folded at 90 degrees, the flaps 28, 50 are folded down, the crease lines 38, 60 are respectively folded at 90 degrees, and the first side cover pieces 36, 58 are overlapped. A first side lid S3 that is glued and closes one opening of the outer cylindrical body S1 is formed.

  In this state, the item W is put into the accommodating part S2. The stored object W is inserted into the opening on the second side cover piece 40, 62 side of the outer cylindrical body S1 from the head W1 side, and stored in the storage part S2. At this time, even if the object W is to be inserted from the side of the body W3, the body W3 hits the protrusion 78a of the connecting portion 78 and does not enter the back. Therefore, it is possible to prevent the stored item W from being stored in the reverse direction.

  After the contents W are put in, the crease lines 34 and 56 are folded forward at 90 degrees, the flaps 32 and 54 are folded down, and the crease lines 42 and 64 are folded forward at 90 degrees and the second side cover piece 40, A second side lid S4 that closes the other opening of the outer cylindrical body S1 is formed by overlapping and gluing 62. This completes the operation of assembling the packaging box 10 with a buffer function and packaging the contents W.

  In the state where the object W is accommodated in the accommodating part S2, the movement in the head W1 direction is restricted by the end side of the upper support part 76, and the movement in the opposite direction is restricted by the second side lid S3. The lateral movement is limited by the side support plate 80 or the projecting portion 78a and the first glued plate 66, and is mostly held without rattling.

  When the person who purchased the contents W opens the packaging box 10 with a buffer function, as shown in FIG. 1, as shown in FIG. 1, the perforation continuous with the opening cut line 46 of the first side plate 14 and the top plate 16. 44 is broken, the opening lid 48 is opened, and the contents W are taken out.

  As described above, in the packaging box 10 with a buffer function, the upper end portion of the side support portion 80 is fixed to the back surface of the second side plate 40 via the connecting portion 78, and the paste piece 82 at the lower end portion is the bottom. It is fixed to the back surface of the face plate 20. Therefore, when an impact is applied from the side of the outer cylindrical body S1, the contents W can be securely held by the side support plates 80 fixed at both ends. Further, even when left for a long period of time, the side support plate 80 is not easily deformed, and good buffer performance can be maintained.

  Further, by adjusting the shape of the upper support portion 76, the connecting portion 78, the projecting portion 78a, and the side support portion 80 in accordance with the shape of the object W, the rattling of the object W is suppressed to a certain level or less. Can do. In addition, the shape of the protrusion 78a is formed along the shape of the head W3, which is a thin part of the storage object W, and cannot be stored from the side of the body part W1, which is a thick part. It is possible to reliably prevent erroneous insertion in the reverse direction.

  Further, the packaging box 10 with a cushioning function is composed of a single box-forming piece 12 having the above-mentioned excellent performance, and can be assembled with one touch after being folded and glued. W packaging work can be performed efficiently.

  In addition, the packaging box with a buffer function of this invention is not limited to the said embodiment. For example, paper or the like is suitable for the material of the box-forming piece, and the selection of the material and the setting of the thickness can be appropriately changed in view of the impact resistance and design properties of the contents.

  Further, for example, in the packaging box with a buffer function of the above embodiment, a structure in which the end portion on the second side lid piece 62 side where the side support portion 80 and the glued piece 82 are continuous is cut in an L shape inwardly. May be added. Thereby, it can restrict | limit by the said raising and raising that the stored thing W in the accommodating part S2 moves to the trunk | drum W1, and the buffer performance which protects the accommodated substance W can further be improved.
