  Therefore, the present invention can provide an apparatus for packaging an article that has a simple structure, is relatively easy to assemble, and has an upright piece with increased strength.

Hereinafter, an embodiment of an article packaging apparatus according to the present invention will be described with reference to the drawings.
As shown in FIG. 1 which is a perspective view illustrating only one of a pair of inner boxes 1 and 1 used in combination, the packaging apparatus for this article has a buffer function, that is, a resilient support function. A pair of inner boxes 1 each having a reinforced standing piece and having a packaging surface in contact with each other as described in detail. A relatively heavy article P such as a portable personal computer is buffered and elastically wrapped in a holding body, that is, an outer box 2 to be described later, and then packaged.

  That is, each of the inner boxes 1 and 1 has substantially the same shape. Therefore, only one of the inner boxes 1 and 1 will be described. As shown in the developed view of FIG. From M, one side edge of the long side is shaped along the direction of the wave line W, and assembled into a flat box shape having a substantially rectangular shape as shown in FIG. That is, the window-shaped opening 3 is formed in the center of the rectangular corrugated cardboard material M to form the window frame 3A-shaped packaging surface 4. The inner edge of the window-like opening 3 is formed in a gentle wave shape including its corners to improve the design aesthetics, and the strength of the window frame 3A is not reduced by stress concentration. . Further, when the inner edge is linear, the operator may injure his / her finger with the sharp edge, but this wavy inner edge can prevent this. Further, although the corners are not clearly shown, the strength can be similarly maintained if they are formed in a relatively large circle from the window-like opening 3 side to a convex or concave shape.

Further, standing pieces 7 and 8 are respectively formed from two parallel side edges of the packaging surface 4 via short side and long side fold lines 5 and 6, respectively. Box-shaped inner boxes 1 and 1 are formed from the corrugated cardboard material M through one assembly step as shown in FIG.
That is, each of the standing pieces 7 is formed with a central standing portion 10 that defines the standing height H at each central portion, and is formed with an end standing portion 11 having a slightly lowered standing height at both ends thereof. Is done. In addition, assembling cuts 12 and 12 are formed on the outer edge located at the boundary between the central upright portion 10 and the end upright portion 11. Each notch 12 is formed such that the side edge of the central upright portion 10 is perpendicular to the fold line 5 and the side edge of the end upright portion 11 is a curved V-shaped opening.

  Similarly, each standing piece 8 has a standing height H, and reinforcing pieces, that is, bent standing portions 13 and 13 are formed at both ends thereof to extend through the folding line 13A at the same height. The tips of the pieces 13 and 13 are slightly lowered in standing height, and at the lower edge thereof, assembling cuts 14 and 14 corresponding to the cuts 12 and 12 of the standing piece 7 are formed. Each of the cuts 14 engages with the cut 12 so that each piece 13 can be assembled while maintaining the standing height H, and the side edge of the fold line 13A is parallel to the fold line 13A. In addition, the outer end side edge is formed to be a V-shaped opening. As shown in FIG. 3 in one process of assembling, the notches 12 and 14 stand from the corrugated board material M through the fold lines 5 and 6 and stand up pieces 7 and 8 as well as reinforcing pieces, that is, folding pieces. The bent upright portions 13 and 13 are bent upright and overlapped with the upright pieces 7, and the whole is assembled in a box shape, and the notches 12 and 14 are inserted into each other to maintain the upright state. As shown in FIG. 1, a flat box-shaped inner box 1 having an open surface 9 is firmly assembled.

  In this case, the bent upright portions 13 and 13 are formed so that the entirety of the bent upright portions 13 and 13 overlaps with the upright pieces 7 as much as possible when they stand up, and the upright pieces 7 as a whole have a two-layer structure. preferable. Therefore, the notches 14 of the bent upright portions 13 and 13 are positioned at the tip as much as possible, and the notches 12 and 12 of the upright piece 7 are provided as close to the center portion as possible. Further, as is apparent from the drawing, the direction of the wave W of the corrugated board material M in the standing piece 7 is orthogonal to the longitudinal direction of the standing piece 7, but the reinforcing piece, that is, the corrugated cardboard of the bent upstanding portion 13. Since the direction of the wave line W of the material M coincides with the longitudinal direction of the upright piece 7, the upright piece 7 is specially reinforced by the reinforcing piece 13.

  On the surface of the window frame 3A outside the packaging surface 4 of the inner box 1, for example, a stretchable transparent elastic sheet 15 such as a polyurethane sheet having a thickness of 50 microns is stretched to constitute the packaging surface 4 To do. As shown in the figure, the elastic sheet 15 is shaped and developed from the corrugated board material M as shown in FIG. 2 in the window frame portion 3A on the outer surface of the corrugated board M on the packaging surface 4 side before assembly. Thus, the entire window-shaped opening 3 is thermally welded to the window frame portion 3A by the heating head of the welding apparatus. Of course, it can also adhere | attach using a suitable adhesive agent as needed.

The article packaging apparatus configured as described above packages the article P in the following steps.
That is, at the time of packaging, two pairs of inner boxes 1 and 1 thus configured are prepared so as to be symmetrically opposed to each other, and as shown in cross section in FIG. An article P, for example, a personal computer such as an electronic device, is arranged on the elastic sheet 15 of the packaging surface 4, and the packaging surface of the other inner box 1 is placed on the opposite side so that the inner boxes 1, 1 are mutually attached. The personal computer is elastically clamped and supported between the two sheets 15 and 15 by contact, and in this state, the pair of inner boxes 1 and 1 are accommodated in the outer box 2 which is a holding body. The personal computer is stably and elastically supported and completes the packaging. Since the elastic sheets of the inner boxes 1 and 1 in this embodiment are transparent, the article P can be visually recognized through the sheet 15 in the packaging operation, so that not only the operation is easy, but also after the packaging, Since the article P can be visually recognized from the outside of the box, it is easy to handle.

  In the above-described embodiment, the outer box 2 is used as a pair of inner boxes 1 and 1 as a holding body. However, if there is no problem in the appearance of the packaging state, the pair of inner boxes 1 and 1 are attached. It is also possible to bond and hold each other with an adhesive tape adhered between the side surfaces, or to use a strip-shaped sheath instead of the outer box and to hold it. Of course, the belt-like sheath may be stretchable like a strong rubber band.

Next, another embodiment of the present invention having a configuration in which the upright pieces 7 of the inner boxes 1 and 1 are further reinforced will be described.
