In addition, the width of the recess m is made narrower toward the upper side so that the recess m protrudes inside the recess m.

A pair of left and right main body packings 102A,
When the members 102B are engaged with each other in a contact state as described above, an article accommodating space having a capacity of two fitting concave portions V is formed therein. Therefore, the main body packings 101A and 101B butted against each other as described above can also be used as an independent packing tool for accommodating articles other than the main body 500 of the personal computer, for example, a cordless telephone in a buffered state. .

The second difference is that in order to avoid interference with the protruding portion of the main body 500, a parallel cut is provided on the inner wall surface 7,
The portion sandwiched between the cuts is bent inwardly into an L-shape as shown in FIG. The edge 15a of the recess 15 is formed not in a straight line but in a wavy line. The reason is that if the lip 15a is straight, the plastic bag for packaging (not shown) over the main body 500 is rubbed by the vibration during transportation and rubbed against the lip having an edge shape, and is worn out. It is because.

The third difference is that, as shown in FIG. 19, the bottom surfaces 8 and 9 are provided with a hollow 16 for avoiding a projection of a packaged article (for example, a cordless telephone). In order to form the hollow 16, a cut 17 and a notch 18 are provided on the bottom surfaces 8 and 9. Therefore, when the packing 102A is folded up, the protruding portion 19 surrounded by the cut 17 extends downward, and plays a role of supporting and supporting the buffer rib 31 located therebelow. The protruding piece 19 is provided with a fitting notch 19 a for avoiding interference with the buffer rib 31.

FIGS. 24 to 26 show another embodiment of the accessory case. One cardboard 300 shown in FIG.
The main points of the accessory case 302 of this embodiment, which is folded from the position B to the form shown in FIG. 26, are different from the accessory case 301 as follows. That is, as shown in FIG.
Parallel cuts 82, 82 are provided at predetermined intervals in a portion straddling the bottom surface 61 and the left and right side surfaces 63, and the band-shaped portion 83 sandwiched between the cuts is bent into an L shape, as shown in FIG. At the place where it protrudes inside the case. As understood from FIG. 26, the L-shaped bent portion 81 plays a role of holding, for example, a tubular accessory 85 such as a print roll in an interference state. 86 is a finger hole.

The interior of the accessory case 302 is divided into two sections by two stacked partitions 84 (see FIG. 24). No. 5-16683 ", and the description is omitted.

In the above configuration, the object of the present invention can be achieved even if the detailed structure is appropriately changed in design. For example,
The peripheral walls of the fitting recesses V and W may be formed with a double structure wall over the entire periphery. In addition, the cushioning ribs 31 and the upstanding auxiliary pieces 3
The formation method, arrangement, number and the like of 3 may be appropriately changed according to the shape and weight of the packaged article. Alternatively, if a perforated half-cut line of an appropriate length is provided at an arbitrary position of the sheet material in a direction orthogonal to the direction in which an external force is applied, the cushioning performance of each part of the packing tool can be improved. Can be adjusted arbitrarily. The sheet material is not limited to corrugated cardboard.
