Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a packaging device that arranges a cardboard frame above the waist.

[Technical background of the invention and its problems]

As shown in FIGS. 1 and 2, reference numeral 1 denotes a corrugated cardboard frame, and a punch hole 3 is bored in the bottom surface 2 of the corrugated cardboard frame 1. As shown in FIGS. Further, reference numeral 4 indicates a lower back made of a plate material or the like, and stoppers 6, 6 for fixing the corrugated cardboard frame 1 are protruded from the upper surface 5 of the lower part. Then, the cardboard frame 1 is inserted into the peripheral portion 8 of the punch hole 3 to the outside 7, 7 of the stopper 6, 6.
are fixed by touching them. Further, an object to be packaged, such as a refrigerator, is loaded inside the cardboard frame 1, and the object to be packaged is covered with a cardboard box. Furthermore, when transporting, insert the forks of the forklift into the openings 9, 9 of the lower waist 4,
It is constructed so that it can be lifted.

However, the peripheral portion 8 of the punched hole 3 of the corrugated cardboard frame 1 is just an open end surface of the bottom surface 2, and has weak strength and is easily torn. Therefore, there was a problem in that the peripheral portion 8 was damaged when the corrugated cardboard frame 1 was fixed to the waist or during transportation.

[Purpose of invention]

The present invention was developed with attention to the above circumstances, and its purpose is to prevent the cardboard frame from moving by simply fitting the punch hole in the cardboard frame to the stopper below the waist, and to prevent the cardboard frame from moving. An object of the present invention is to provide a packaging device that can improve the strength of the packaging device.

[Summary of the idea]

In this invention, multiple punch lines are provided on the bottom of the cardboard frame, and between these score lines, the bottom surface is folded back to the top to form a punch hole, and the folded part of the punch hole is brought into contact with a stopper below the waist. It has been fixed.

[Example of idea]

Hereinafter, one embodiment of the present invention will be described based on the drawings. As shown in Figures 3 to 5, 11
is a cardboard frame, 12 is below the waist, and this below the waist 12
A plurality of stoppers 14, 14 for fixing the corrugated cardboard frame 11 are protruded from the upper surface 13. Further, the cardboard frame 11 has a rising portion 15 on the periphery, and a punch hole 17 is bored in the bottom surface 16 to be fixed to the lower part of the waist 12.

Here, the formation of the punched hole 17 will be described. First, a rectangular through hole 18 of an appropriate size is bored in the vicinity of the center of the bottom surface 16 in parallel to the cardboard frame 11. Further, incision lines 21 are provided from the four corners 19 of the through hole 18 toward the four corners 20 of the rising portion 15. Then, the folded pieces 22 between the cut lines 21 are folded back to the upper surface side of the bottom surface 16, and the cut lines 21 …
Adjust. Furthermore, the folded pieces 22 are fixed to the bottom surface 16 with stitches or adhesive,
The punch hole 17 is formed. This cardboard frame 11
When installing the above below the waist 12, use the above punch hole 1.
The folded parts 24, 24 of 7 are connected to the stopper 1.
4, 14 and fix it.

Thus, the punch hole 17 has a double structure by folding back the bottom surface 16, and its strength is increased. Therefore, even when the corrugated cardboard frame 11 is fitted into the stoppers 14, 14 of the lower waist 12, or when transported by a forklift, damage to the punch holes 17 can be prevented.

Note that the shape of the punched hole is not limited to a rectangular shape, but may be polygonal, and this does not prevent the tips 23 from coming into contact with the rising portion 15.

[Effect of idea]

As explained above, according to the present invention, a punch hole is formed by folding back the bottom surface of a corrugated cardboard frame, resulting in a double structure. Therefore, it has excellent strength, and the above-mentioned punch-out hole can be damaged even when the above-mentioned punch hole is brought into contact with the stopper below the waist to fix it under the waist, or when it is moved back and forth and left and right when being transported by forklift. can be prevented.
