Description

[Detailed Description of the Invention] The present invention relates to a packaging device for a refrigerator or the like, and is particularly aimed at reducing the amount of materials such as corrugated paper used.

Conventionally, from this point of view, for example, one side has been partially die-cut and the cut material produced by this die-cutting is reused as a flap in a package, a corner cushion, etc., but the present invention The purpose of this is to take into account the shape at the time of die cutting, prevent a decrease in the rigidity of the case due to die cutting, and put it into practical use.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

Reference numeral 1 denotes a cylindrical case made of corrugated paper with open upper and lower surfaces, and has a front surface 1a, a rear surface 1b, and both side surfaces 1c and 1d. 2 and 3 are openings formed by die cutting on both sides, and residual portions 2a and 3a are formed at each corner of the openings 2 and 3, extending diagonally toward each other. The overall shape is approximately a cross. Reference numerals 4 and 5 indicate blanks produced by forming the openings 2 and 3. One punched piece 4
The top plate 6 is constructed by bending opposing sides to form a locking piece 4a. In addition, the opposite sides of the other punched material 5 are bent into a chevron shape along the two-dot chain line shown in FIG.
A pair of lower cushioning bodies 6 made of styrofoam etc.
The locking piece 5a is formed to constitute the bottom plate 7.
8 is an upper buffer body. A band 9 binds the bottom plate 7, the cylindrical case 1, and the top plate 6 together. Further, reference numeral 10 denotes reinforcing adhesive tapes attached to the back surfaces of the upper and lower sides of the openings 2 and 3.

According to this configuration, the substantially cross-shaped openings 2 and 3
has residual portions 2a and 3a at each corner thereof, so both sides 1c and 1d of the cylindrical case 1 with the openings 2 and 3 have corner portions where stress is concentrated especially during transportation or loading. It is reinforced and the decrease in rigidity of the case as a whole can be minimized. On the other hand, the top plate 6,
In constructing the bottom plate 7, the width of the locking pieces 4a and 5a does not necessarily require the entire width of the top plate 6 and the bottom plate 7, and both ends are cut off to form the remaining parts 2a and 3a. This is convenient because the locking portions of the buffer bodies 6 and 8 are formed.

As described above, the present invention forms an approximately cross-shaped opening on any surface of a cylindrical case having a front surface, a rear surface, and both side surfaces, with the remaining portion remaining at each corner, and a cutout of this opening. It is equipped with a top plate or a bottom plate with a locking piece that locks the shock absorber by bending opposite sides of the case, and the corners of the case are reinforced by the remaining parts at each corner. This method is suitable for packaging heavy objects such as refrigerators, and reduces the amount of materials used such as corrugated paper. This makes packing work easier.
