Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cardboard case particularly suitable for packaging heavy objects, and is characterized in that it can be easily wrapped around the heavy objects.

Conventionally, when packaging heavy products such as refrigerators, coolers, bathtubs, etc., the above-mentioned product is lifted up by a crane or the like and inserted into a corrugated hole case with a bottom affixed, and the lid flap is folded, or the method described above is used. A method of packaging the product by fitting it with a corrugated pole case that expands from above into a cylindrical shape has been adopted.

In the first method above, it takes a lot of effort to hang the product without damaging it, and also to insert the hanging member so that it does not remain inside the corrugated pole case. The drawback is that it requires a lot of time.

Furthermore, the second method has the disadvantage that it is difficult to fold the bottom flap.

The present applicant has already proposed a method for eliminating the drawbacks of the second method described above, which has already been proposed in Patent No. 88543 (% Publication No. 49-4887).
The present invention provides a packaging method according to Patent No. 0) and a corrugated pole case according to Patent No. 879625 (Japanese Patent Publication No. 52-4237).

The corrugated pole case of the present invention further advances the above-mentioned conventional packaging concept, and allows the product to be easily packaged by winding the expanded corrugated hole sheet around the product.

Therefore, heavy items can be easily packaged by humans.

An embodiment of the present invention will be described in detail below with reference to the drawings.

The corrugated cardboard case of the present invention has a body part f21 which is a cylinder of a corrugated cardboard sheet (1) that has been expanded in advance according to the product to be packaged.
(2α) One end portion of (2A) and (2C), specifically the body portion (21?) K overlap piece +31 is provided.

The overlap piece f31 and the overlap piece (3
) is superimposed on the corrugated pole sheet (1) body f21 (2
α) The other end of (2b) and (2C), specifically the body (
2) are each provided with a magic fastener +41 (4α).

For spear 1 to spear 3 illustrations, magic fastener F41
When (4α) is a cylinder, it is configured to be located inside. In addition, in the case of the example, magic fastener +
41 (4α) is provided on all of the ends of the body (2) and (2C), but it may be provided only partially. Furthermore, figures 1 to 3 of the spear are the body parts (2) (2α) (2h) and (2C).
) above the lid flaps (51 (5(Z) (
5b) and (5c), and an example in which bottom flaps (61 (6a) (6A) and (6C) are respectively configured below) is shown.

Similar to the cardboard case used in the method, a notch (71 (7α)) may be provided to fit into the transport rail.

The cardboard case of the present invention having the above structure is wound around the product, a magic fastener f41 (4α) is polymerized and fixed, and then an appropriate method is used, for example, Patent No. 989944 (Japanese Patent Publication No. No. 22157) Ic
The bottom flap (61 (6 (Z) (6A)
(6e) Fold IF, and further fold the lid part f51 (5α) (1) and (5c) to the light emitting surface using a conventionally provided method.

Other embodiments are shown in Figures 4 to 6. That is, the bottom flaps (6) (6α) (6A
) and (6c) are not included, a separate bottom holding plate (8) is used, and the overlap piece 131 is superimposed and fixed on the outside of the trunk +21.

In this case, the product is placed on the bottom holding plate (8), and the magic fastener +41 (4α) is wrapped around the product in the same way as in the previous embodiment to overlap and fasten the product, and then the bottom holding plate (8) and the lower ends of each body (2) (2α) (2h) and (2c) are fixed with nails or adhesive, and the lid flap [51 (5a) (5h) and (5c) is It is sufficient to fold the beam surface using a known method.

In addition, the lid flap (5) is attached to the bottom holding plate (8).
(5a) (5h) and (5c) folding ntano? ), up and down! This is also possible by multiplying by the c-band.

As described above, according to the present invention, unlike conventional packaging methods, it is possible to wrap particularly heavy goods in the lateral direction, that is, roll packaging, and it does not require much packaging equipment or work space, e.g. This allows for quick packaging even if one roll is done manually.
