Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a packing case, and more particularly, to a wrap-around packing case that has improved sealing performance when resealing and is easy to unpack.

[Conventional technology]

Conventional techniques for unpacking wrap-around packing cases include providing cuts or cutting tape at appropriate locations on the sides, or removing part of the top surface in the form of tape (for example, Jikkosho Publication No. 49-6330, Publication No. 1987-
Publication No. 60978, Publication of Utility Model Publication No. 1983-46986, Publication of Utility Model Publication No. 1987
-80218 Publication).

Additionally, Utility Model Application Publication No. 48-46032 discloses a packing case in which opening cuts are provided on three of the four ridge lines surrounding the top surface of an upright three-dimensional packing case. There are official gazettes and Utility Model Application Publication No. 55-7716.

[The problem that the idea aims to solve]

However, in the conventional technique, when cuts are provided at appropriate locations on the side surface, the strength of the packing case is reduced. Further, in order to prevent such a decrease in the strength of the packing case, cut tape can be used, but this increases the cost. Therefore, in order to avoid a decrease in strength and an increase in costs, it may be possible to provide a cut on the top surface for opening the package.
In that case, in the conventional technology, a part of the top surface is removed, so when the package is resealed, a part remains open, which causes problems such as easy entry of dust, which reduces the commercial value of the packaged item. It was hot.

Also, the above-mentioned Utility Model Application Publication No. 48-46032 and Utility Model Application No.
The packing case described in Publication No. 55-7716 solves the above problems, but the former packing case does not have any opening means other than the opening cut 12, In addition to the opening cutout 8, the latter packing case is also provided with a push-in cutout 7 as an opening means. There were problems in that it was difficult to open the package unless the package was pushed in, and if the contents were tightly packed, it was virtually impossible to open the package.

[Means to solve the problem]

In the present invention, the top part, the first side part, the bottom part, and the second side part are successively connected in series through folding lines, and flaps are attached to the upper and lower edges of these parts through the folding lines. It has a shape in which the body pasting part is connected to the side edge of the second side part through a fold line, and the third side part is connected to the third side part by four flaps connected to the upper edge. In a packing case formed into a rectangular parallelepiped shape by folding and assembling one plate-like body, each of which has four flaps connected to the lower edge to form a fourth side surface, the packing case is used for opening. Cuts are formed in the continuous portions of the second side surface and the body patch, and in the continuous portions of the top surface and the two flaps connected to the upper and lower edges of the top surface. The side part is provided with a finger-pushing part forming cut consisting of a pair of cuts or perforations extending from the fold line between the body pasting part and the bottom part, and the second side part and the body are connected. The opening cut formed in the continuous part of the adhesive part is
It consists of a large number of approximately dogleg-shaped cuts consisting of a cut and a second cut, each first cut is provided in the form of a perforation on the fold line between the second side part and the body pasting part, and To provide a packing case characterized in that each of the second cuts is located closer to a finger-pushing part than each of the first cuts, and is provided symmetrically in the body pasting part with the finger-pushing part in between. This solves the problems of conventional packing cases.
