Description

  The present invention relates to an unauthorized opening prevention carton that can prevent unauthorized opening in a wrap round carton that is not attached to a case.

  Conventionally, there is a lapland type carton in which the side surface of the carton is not pasted (body pasted). For example, a conventional carton for packaging and packaging individually butter is configured as shown in FIGS. As shown in FIG. 7, the unfolded carton blank plate has a side plate 3 connected to the top plate 1 via a fold line, and a bottom plate 2 connected to the side plate 3 via a fold line. Yes. An upper overlap side plate 5 is connected to the top plate 1 and a lower overlap side plate 4 is connected to the bottom plate 2 via a folding line.

  Side flaps 3 a and 3 b are provided on both sides of the side plate 3, and side flaps 5 a and 5 b are provided on both sides of the upper overlap side plate 5 via folding lines, respectively. The flap 4a is continuously provided via a folding line.

  The top plate 1 has a sack type main flap 7 having an insertion flap 7a at the tip, and the bottom plate 2 has a sack type main flap 6 having an insertion flap 6a at the tip on the opposite side of the sack type main flap 7. Each is connected via a folding line.

Next, a packaging method for individual packaging using the carton will be described.
First, as shown in FIG. 8, the side plate 3 is bent as shown in FIG. 8, and a U-shaped form is inserted into the body formed by the top plate 1, the side plate 3, and the bottom plate 2. Next, the side flaps 3 a and 3 b are bent inward from the side plate 3 and the lower side plate 4 is raised from the bottom plate 2. Thereafter, the upper side plate 5 is stacked from above the lower side plate 4 and the side flap 5b is folded inwardly facing the side flap 3b together with the side flap 4a, and the side flap 5a is also opposed to the side flap 3a inward. Bend it. Then, the insertion flaps 6a and 7a of the sack type main flaps 6 and 7 are inserted into the trunk portion, and the individual packaging is provided by overlapping the side flaps 5a and 3a and the side flaps 5b, 4a and 3b. In order to take out the individual package from the carton, the carton can be opened and taken out by pulling out the insertion flaps 6a, 7a of the sack type main flaps 6, 7. Here, “individual packaging” means contents stored in a carton or packaged contents.

  In the above conventional lapland type carton without sticking the trunk, by pulling out the sack type main flap from the trunk part, it is possible to take out the butter etc. that are individually mounted from the carton, but since there is no mark for unauthorized opening, it is illegally opened. But I don't know from outside.

  As a technique that can easily identify whether or not this tampering has been opened and prevent tampering, Patent Document 1 discloses that the length of the side flap is at least 40% of the carton width and the seal end. Cut the main flap on the lower side of the opening tab without cutting into the first section on the folding line of the opening tab in the perforation or zipper at the opening of the main flap. A technique for notching a sack type main flap that overlaps with a flap is disclosed. That is, in this technique, the length of the side flap is set to at least 40% of the carton width. Therefore, even when trying to open the upper side plate that is not attached to the body, the side flap is long, so it is not easily opened, and is forcibly pulled. If it is torn from the fold line or has a perforation on the fold line, it can be easily cut off from the perforation, and it can be seen that it has been tampered with.

Moreover, in patent document 2, a zipper, a perforation, etc. are provided in the ridgeline part of a top | upper surface so that it can be opened over all the ridgeline parts of the surface which comprises the top | upper surface of a carton in the wrap round type carton of the body-paste type Of the top plate, bottom plate, and side plate, the middle flap is subjected to window cutting or cutting, and adhesive is applied to this part, so that the three flaps are pasted together. A carton that is worn and does not decompose into a branch and leaf state even after the top surface is opened is disclosed.
