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 refrigerators, air conditioners, bathtubs, and other products with heavy loads, the above-mentioned product is lifted up by a crane or the like and inserted into a cardboard case with a bottom affixed, and the lid flap is folded or the above-mentioned product is placed above the product. A method of packaging the product by fitting it into a cardboard case expanded into a cylindrical shape has been adopted.

According to the first method above, /i3 lowering without damaging the product,
Furthermore, it takes time and effort to insert the hanging members so that they do not remain inside the cardboard case, and there is also the drawback that the workspace requires two floors of space.

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

The 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 (Japanese Patent Publication No. 49-4887).
We provided a packaging method according to Patent No. 0) and a cardboard case according to Patent No. 879625 (Japanese Patent Publication No. 52-4237).

The cardboard case of the present invention further advances the above-mentioned conventional packaging concept and enables easy packaging by winding a corrugated cardboard sheet developed around the product.

Therefore, it is possible for one person to easily pack heavy items.

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

The cardboard case of the present invention has a body (21
(2α1 Both ends of (2h) and (2C), specifically the body (2) and C2C) are provided with curved parts (3) and (4) that protrude outward and become back-to-back when made into a cylinder. .

In the case shown in FIGS. 1 to 3, the curved portion may be constructed by pasting a different material, such as a thin metal plate or a thin plastic plate, to each corrugated cardboard sheet. Furthermore, FIGS. 1 to 3 show the body (2).
Lid flaps f51 (5a) (sb) and (5C) are formed above 1 (2a) (2b) and (2C), respectively, and bottom flaps (6) C6α) are formed below, respectively.
Examples of configurations of (6A) and (6C) are shown.

In addition, the bottom flap [61 (6α) (6A) and (6C
), for example, the bottom flaps (6α) and (6C) may be provided with a notch IIH7a) that fits into the transfer rail, similar to the corrugated pole case used in the packaging method of Patent No. 88543. 6 Furthermore, the present invention has a clamping piece' (8) that holds both the curved parts (3) and (4).
) is prepared. - The cardboard case of the present invention having the above structure is wrapped around the product to form curved parts (3) and (4).
) are placed back to back, and a separately prepared clamping piece (8) that holds the curved portions (3) and (4) is fitted from above. Bottom flap +6H6α) (6h) and (6C
), and then the cover f51 (5α) (5, 6) and (5C) are folded and exposed using a conventionally provided method, and the straps may be attached equally for handling purposes.

Another embodiment is shown in FIG. That is, the bottom flap f6+(6α) (6b) and (
6C), and a bottom holding plate (9) is used for each box.

In this case, the product is placed on the bottom holding plate (9), and the holding piece (8) is wrapped around the product in the same way as in the previous embodiment.
) to hold the curved parts (3) and (4), and securely attach the lower ends of the bottom holding plate (9) and each body part (21 (2αl (2,b) and (2C) with nails or adhesive). However, the lid flaps +51 (5α) (5A) and (5C) may be folded and exposed using a conventional known method.

Also, the lid flap (5H) is fixed to the bottom holding plate (9).
5α) This can also be done by folding (5b) and (50) and then placing bands on the top and bottom.

Fig. 5 shows a case in which curved parts (3) and (4) are formed from a different material, for example, a thin metal plate, on the outside of the ends of the body parts (2) and (2C), and Fig. 6 shows the case where the curved parts ( 31 and (4)
This is the case if the mud is stored inside the cardboard sheet (1).

In any of the above cases, the clamping piece (8) is preferably made of an elastic material. In that case - both curves (3) and (4) of E.
In addition to fitting from above, it is also possible to fit from the side.

As described above, according to the present invention, unlike conventional packaging methods, it is possible to wrap particularly heavy goods from the lateral direction, that is, roll packaging, and it does not require much packaging equipment or work space. For example, rapid packaging is possible even if winding is done manually.
