JPS6020610Y2 - Bottom plate for storage warehouse packaging - Google Patents

Description

[Detailed description of the invention] This invention is a packaging device for storage such as a small refrigerator, compared to the conventional packaging bottom plate on which the storage is placed by pasting a cushioning material such as styrofoam on cardboard. To provide a bottom plate for packaging which can omit the above-mentioned cushioning material, can maintain sufficient support strength for the storage, and can accurately form insertion holes for support legs provided at the bottom of the storage.

Next, embodiments of the present invention will be described in detail based on the drawings.

Reference numeral 1 is a long corrugated cardboard with a rectangular shape, and a linear first cut 4 passes through the thickness of the corrugated cardboard 1, leaving a pair of connecting parts 3A and 3B across the opposing long sides 2 and 2. Linear first half cuts 5 that reach the middle of the board thickness are alternately formed inward from both ends of the corrugated board 1 at a predetermined interval, and connecting portions 3A and 3B each have a cut 4 at both ends. A notch 6 is formed which extends through the thickness of the corrugated board 1 and is parallel to the long side 2.

7 is a hole formed in a portion corresponding to the connecting portions 3A and 3B.

In this structure, the pair of laminated parts 8A and 8B can be formed by sequentially bending the cut 4 and the half cut 5 as shown by the arrow P in FIG. 2 and stacking them in a meandering shape.

Between the laminated parts 8A and 8B, parallel second cuts 9A and 9B extend in parallel along the long side 2, penetrate through the thickness of the corrugated board 1, and intersect with the cut 4 with one end located inward; A linear third cut 10 passing through the thickness of the corrugated board 1 and a linear second half cut 12 reaching the middle of the board thickness are alternately made over 9A and 9B, leaving the second connecting portion 13. They are formed at predetermined intervals.

Furthermore, each of the connecting portions 13 has cuts 11 extending through the thickness of the corrugated board 1, intersecting the cuts 10 on both sides and parallel to the cuts 9A and 9B.

In this structure, the cut 10 and the half cut 12 are sequentially bent as shown by the arrow Q in FIG. 2 to form a second laminated portion 14 stacked in a meandering manner.

A pair of notches 9A and 9B intersects with notch 4, but notch 9A.

There is no problem even if another cut extending over 9B is formed.

Further, a U-shaped cut 15 adjacent to the laminated portion 14 and facing the laminated portion 14 is passed through the cardboard 1 to form a flap portion 17, and parallel bent portions intersect with the opposite sides of the cut 15. 16, and by bending the flap portions 17 at right angles at the bending portions 16 as shown by the arrow R in FIG. .

The packaging bottom plate completed in this way is shown in FIG. 3, and after inserting this packaging bottom plate into the packaging outer box 19 made of cardboard as shown in FIG. When inserted into the interior, the support legs 21 with or without rollers provided on the bottom of the storage 20 are inserted into the holes 7 of the laminated parts 8A, 8B, and the bottom of the storage 20 has both sides connected to the pair of laminated parts 8A, 8B. In addition, the central portions are each supported by the second laminated portion 14 via the wrapping portion 18.

In the above configuration, each cut, half cut, and hole can be formed by punching the cardboard 1 with a punching machine.

In this invention, as described above, each laminated part can be formed by notches and half-notches in the rectangular cardboard, and by forming insertion holes for the support legs of the storage in the pair of left and right laminated parts, each laminated part can be formed by notches and half-notches. The holes can be easily formed by sequentially bending them into a meandering shape, and the holes become a series of deep holes by this bending, so that the holes can be formed at precise positions.

Therefore, the load of the storage can be received by the laminated parts on both sides and the center of the bottom, and the support legs can be inserted into the holes accurately, so that the storage can be placed on the packaging bottom plate stably and accurately.

This is because in the conventional model, the cushioning material was pasted on the left and right ends of the top surface of the cardboard bottom plate, which made the work of pasting it cumbersome. If this hole is made too large due to assembly errors, it will be difficult to position the storage on the cushioning material. However, the present invention can solve this problem.

Furthermore, the second laminated portion can sufficiently protect the storage compartment from the upward force acting from below between the pair of left and right laminated portions, and can also effectively prevent deformation of the bottom plate itself.

In addition, each laminated portion has sufficient cushioning properties, making it suitable as a bottom plate for packaging.

In addition, the predetermined laminated portion can be formed simply by punching and bending the cardboard, so the price is very low.

Note that the laminated portion may be prevented from elongating with adhesive tape, if necessary.
