Description

The present invention relates to a packaging box used for transporting goods and the like. Specifically, a packing box provided with easy dismantling means for easily disassembling the packing box on two flaps arranged inside the assembly box among the four flaps of the lower opening. Regarding.

For the transportation of goods and the like, a box made of thick paper such as corrugated cardboard has been conventionally used as a packaging box. Generally, in such a braided box, a method is adopted in which flaps connected to the side wall of the braided box are overlapped, the outer flap and the inner flap are adhered with an adhesive, and the flaps are sealed and packed.

In the above case, in order to prevent natural opening during transportation, damage to the product, and intrusion of foreign matter, the sealing with the adhesive of the assembled box maintains a relatively strong state.

On the other hand, in the case of the assembled box sealed as described above, it is necessary to remove the adhered flap in order to take out the products and the like inside, which requires a considerable amount of labor for the person who opens the box. In particular, in order to open a packaged box that has been sealed in a strong state, a strong force enough to destroy the assembled box is required, so that there is a problem that women and the elderly cannot open the box.

Therefore, a method for easily opening the above-mentioned packing box has been proposed (Patent Documents 1 to 7).

However, the conventional method for opening the packing box is a method for opening the package when taking out the product or the like after transportation, and a method for disassembling the packing box after taking out the product, which is a so-called easy dismantling means, has been proposed. I wasn't.

Therefore, the present invention has been made in view of the above circumstances, and provides a packing box provided with an easy dismantling means for easily dismantling a used packing box after transportation of a product or the like. This is the subject. In particular, we will provide a packaging box that can be easily disassembled even by people who are relatively difficult to disassemble with conventional packaging boxes, such as women and the elderly, and that can be efficiently disassembled by the general public.

As a result of intensive research, the present inventor has made it possible to easily disassemble the packing box into two flaps arranged inside the braided box among the four flaps of the lower opening of the braided box. The present invention has been completed by finding that the above-mentioned problems can be solved by providing an easy-to-disassemble means for the above-mentioned problems.

The packing box provided with the easy dismantling means of the present invention can be easily disassembled by human hands without using a special machine or tool. Furthermore, even people who are relatively difficult to disassemble with conventional packaging boxes, such as women and the elderly, can disassemble a large number of packaging boxes, which can contribute to improving productivity at distribution sites.

Hereinafter, an example of the embodiment of the packing box of the present invention will be specifically described with reference to the drawings. The present invention is not limited to these embodiments.

As shown in FIGS. 1 to 8, the packing box (1) of the present invention has two flaps (2, inner flaps) arranged inside the braided box among the four flaps of the lower opening of the braided box. ) Is equipped with easy dismantling means.

The easy dismantling means of the packing box of the present invention includes a dismantling guide portion (3) including an opening (4) for inserting a finger when dismantling the packing box. It is preferable that the dismantling guide portion is provided on the inner flap of the assembly box, and a folding line (5) is formed between the flap and the dismantling guide portion so that the flap can be easily bent. The shape of the dismantling guide portion is not particularly limited, but it is preferably trapezoidal so that it can be easily processed and bent at the time of dismantling.

The opening of the dismantling guide portion of the present invention is not particularly limited, but may be round, trapezoidal, square, rectangular, or polygonal so that a finger can be inserted and the dismantling guide portion can be easily pulled during dismantling. .. Alternatively, it may be configured with a line that is easily broken and can be opened at the time of dismantling. The latter case is preferable because it is easy to process, damage and deformation during transportation can be prevented, and the finger does not hurt when the dismantling guide portion is pulled during dismantling.

The dismantling guide portion of the present invention may be provided with an insertion port (6) into which a finger is inserted in order to float the dismantling guide portion in order to allow a finger to be inserted into the opening opening. The shape and size of the insertion slot are not particularly limited, but for example, a trapezoidal notch of 20 to 50 mm can be processed at low cost without using a special processing machine, and further, the strength during transportation can be increased. The area of the inner flaps is maximized for improvement and damage prevention, and even if the dismantling guide part of each flap is in close contact and the finger cannot be inserted into the opening, put the finger in the insertion port and dismantle. It is possible to float the guide portion, which is preferable.

In the packing box of the present invention, a break portion (7) for facilitating disassembly can be provided in the adhesive application portion. The shape of the broken part is not particularly limited, but the two flaps (8, outer flaps) arranged on the outside of the braided box among the four flaps of the lower opening of the braided box are guided to be disassembled at the time of sealing. It is preferable to process the adhesive portion of the portion in contact with the portion into a shape such as a round shape or a polygonal shape. By providing a plurality of cut lines (break lines), the broken portion is broken when the dismantling guide portion is pulled at the time of disassembling the packaging box, and the adhesive portion can be peeled off with a weak force.

In order to fully exert the effect of the broken portion (7) of the packing box of the present invention, it is preferable to adjust the application position of the adhesive (9) on the broken portion (FIG. 7, however, the adhesive and the broken portion). In order to make it easier to check the overlapping part with, the broken part of the overlapping part is erased). Specifically, the end of the adhesive on the contact side of the break in the break is 1/4 to 3/4 of the length of the break in the opening direction (range A in FIG. 7). It is preferable to install the adhesive so as to be. If the adhesive is installed at a position exceeding 1/4 to 3/4, the end portion may come off from the broken portion when the packing box is assembled. As a result, problems such as the broken portion not functioning and the operation of floating the dismantling guide portion cannot be performed, or the bottom surface of the packing box being opened during transportation, which is not preferable.

In the packing box of the present invention, an easy-opening means can be provided in the upper opening of the assembled box. The easy-opening means can improve the workability at the time of taking out the product and alleviate the labor burden. The easy-opening means is not limited, but known techniques may be used.

The material of the packing box of the present invention is not particularly limited, but thick paper such as corrugated cardboard, which is generally used in a shipping box, can be used. Further, the processing method of the packaging box of the present invention is not particularly limited, and although it can be manufactured by a general processing method, the thick paper at the upper and lower openings of the packaging box is cut so as not to cause injury when the packaging box is opened or disassembled. It is preferable to apply an injury prevention process to the surface.

Like the conventional packing box, the packing box of the present invention does not require any special material or processing, and can be manufactured at low cost. On the other hand, compared to conventional packaging boxes, it is superior in workability when dismantling and disposing of after use, and in particular, conventional packaging boxes such as women and elderly people do not use special machines or tools. Even people who have difficulty in disassembling can disassemble a large number of packaging boxes, which can contribute to improving productivity at distribution sites.
