[Problems to be solved by the invention] However, in recent years,
As consumers' environmental consciousness has increased, their daily life has been reviewed and their consumption behavior has changed. Consumers are now demanding packages that take environmental issues into account.
The aforementioned double wall carton is considered easy to assemble at the time of use, but the assembled box is designed so that the engaging portion of the side wall is difficult to disassemble to maintain strength, and therefore, the box after use is At the time of disposal, households either throw them away as they are, or housewives struggle to crush the side walls as much as possible, causing the problem that the garbage is very bulky. The present invention is an easy-to-disassemble double-walled carton in which the bottom plate and side walls of the carton have been devised in advance so that they are not as bulky as possible when disposed after use.

[0004]

According to the present invention, an outer wall plate and an inner wall plate are sequentially connected to four sides of a square bottom plate, and the outer wall plate, the inner wall plate and the flaps attached thereto are provided. In the double wall carton assembled by engaging
An easy-to-disassemble double-walled carton, characterized in that zippers having cutting start tabs are provided continuously from the center of the bottom plate to both at least two outer wall plates facing each other.

The above-mentioned double wall carton is a frame type double wall carton having an upper edge plate between the outer wall plate and the inner wall plate, even if the outer wall plate and the inner wall plate are continuous. A wall carton may be used.

[0006] The zipper is also called a tear strip. The zipper is a stripping piece for cutting provided side by side so as to face a hook-shaped cut line. It is formed simultaneously with blank punching. And the position to provide the zipper is
Depending on the design strength of the carton, there are ones provided on the outer wall plate from the center of the bottom plate, and those provided from the center of the bottom plate to the inner wall plate across the outer wall plate. And if necessary, for the former, a perforation line may be further provided on the extension of the zipper on the inner wall plate to facilitate disassembly, and for the latter, so as not to impair the strength as a carton. Therefore, it is not necessary to partially provide a zipper near the boundary between the outer wall plate and the inner wall plate. further,
Even in the former case, it is not necessary to partially provide a zipper or perforation in consideration of the strength of the carton.

Also, in assembling the double wall carton of the present invention, it is assumed that no gluing is used.

[0008]

When the double-walled carton of the present invention is discarded after use, the carton is turned over, and a zipper provided from the center of the bottom plate to at least two outer wall plates opposed to both sides is used for cutting. Cut with a knob piece, and further, the part where the zipper is not provided is broken along the extension of the zipper,
The carton is split into two pieces from the center. And since the divided carton has no glued portion, it can be easily folded flat and the garbage in the carton does not become bulky at the time of disposal.
