Description

[Detailed description of the invention] "Industrial application field" This invention prevents the point of a knife from being inserted directly into the adhesive part of the container even if the container is intentionally peeled off and opened with the tip of a knife. The present invention relates to a peelable and tamper-proof container that allows even an untrained eye to determine that the seal has been intentionally opened if the seal is forcibly opened.

``Prior art'' Recently, a crime has occurred in which poisonous substances are mixed into sweets, etc.
Conventional confectionery containers can be easily peeled open with the tip of a knife, etc., and if the container is skillfully opened and a poisonous substance is mixed into the container, and the container is re-closed, no trace of the poisonous substance will remain to the untrained eye, and the poisonous substance will be removed. There is a risk of unknowingly purchasing and eating sweets, etc. that have been contaminated with confectionery, so it is recommended to add shrink-wrapping over the top of the container, which makes it easy to tell at a glance that the package has been opened, but is difficult to reseal. However, this method requires shrink-wrapping on top of the conventional packaging container, which requires expensive shrink-wrapping equipment and double-wrapping, which increases packaging costs. It does have its shortcomings.

``Problem that the invention attempts to solve'' The container itself should be made so that it cannot be easily peeled off and opened.
If you forcefully open the package, it will leave traces of opening.
Moreover, the purpose is to reduce equipment costs and packaging costs.

"Means for solving the problem" A lower flap and an upper flap are connected to the front and rear of the bottom plate and the top plate so as to close the front and rear open ends of the rectangular cylinder consisting of the bottom plate, right side plate, top plate and left side plate. A container in which the front and rear open ends are sealed by bending the top and bottom flaps and pasting the top and bottom flaps together, with a tongue protruding from the center of the tip of the top flap, and a continuous fold between the bottom flap and the bottom plate. Make a U-shaped cut in the bottom plate that is smaller than the tongue piece starting from the top end, cut out the tongue piece sticking piece from the bottom plate, and make it outside from the ending end of the U-shaped cut on the continuous fold. A small cut is provided in the tongue, and the tongue piece is inserted between the U-shaped cut and the small cut, and the inner surface of the tongue piece and the outer surface of the tongue piece sticking piece are adhered.

"Function" A small cut is made on the continuous fold between the bottom plate and the lower flap on the outside from the end of the U-shaped cut, and the tongue at the tip of the upper flap is made between the small cut and the U-shaped cut. The piece is inserted between the bottom plate and the tongue sticking piece cut out from the bottom plate, and the inner surface of the tongue and the outer surface of the tongue sticking piece are stuck, so the sticking part is not exposed to the outside. Even if you insert the tip of a knife from any angle, it cannot be peeled off, and if you try to forcefully open it, the only way to do so is to cut the tongue off from the top flap, and it will be returned to its original state. cannot be occluded.

``Example'' Now, the attached drawings showing an example of implementing the present invention will be explained in detail.

1 is a bottom plate, 2 is a right side plate connected to one side of the bottom plate 1, and 3 and 4 are a top plate and a left side plate connected to the side edge of the right side plate 2 in sequence. 5 is a square cylinder,
A glue margin piece 15 is provided in series on the other side of the bottom plate 1, and the glue margin piece 1
5 is attached to the inner side end of the left side plate 4 as shown in FIG. 4, and the right side plate 2 and the left side plate 4 are made to stand up from the bottom plate 1 and formed into a cylindrical shape. 6, 6 is the bottom plate 1
Lower flaps 7 and 7 are connected to each other through folds 11 and 11 at the front and back of the top plate 3, and upper flaps 7 and 7 are connected to each other at the front and back of the top plate 3. Reference numerals 8, 8, 9, and 9 designate folding flaps that are connected to the front and back of the right side plate 2 and left side plate 4, respectively. Reference numerals 10 and 10 denote tongue pieces, which are connected to the center portions of the tips of the upper flaps 7, 7 via folds 7a, 7a. Reference numerals 12 and 12 refer to the tongue piece 10 that is perforated on the bottom plate 1 and ends at the center of the continuous folds 11 and 11 between the bottom plate 1 and the lower flaps 6, 6.
The bottom plate 1 surrounded by the smaller U-shaped cuts 12, 12 and the continuous folds 11, 11 is divided into tongue sticking pieces 13, 13. 14,
Reference numeral 14 denotes a small cut, which is made on both sides of the continuous folds 11, 11 in a continuous manner with the starting and ending ends of the U-shaped cuts 12, 12.
The width of the U-shaped cuts 12, 12 smaller than 0.10 is widened, and when inserting the tongue pieces 10, 10 on the front and back of the inner surface of the bottom plate 1, align them with the U-shaped cuts 12, 12,
It is provided with a width sufficient to fit the tongue pieces 10, 10. Reference numerals 16 and 16 indicate adhesion flaps formed on the front and rear extensions of the adhesive strip 15, and fold-in flaps 9 that are connected to the front and rear of the left panel 4 when attaching the adhesive strip 15 to the inner surface of the side end of the left panel 4. , 9, and even if the adhesive part of the left side plate 4 and the adhesive flap 15 is peeled off with the tip of a knife, the folding flaps 9, 9 and the adhesive flaps 16, 16 will not stick together. This prevents the tip of a knife from reaching the left side plate 4, thereby preventing the left side plate 4 from being opened.
Reference numeral 17 designates a known opening zipper provided on either one of the front and rear upper flaps 7, 7 of the top plate 3.

The present invention has the above-mentioned structure, and when assembling it, the front and rear folding flaps 8, 8,
9, 9 inward, and the lower flaps 6, 6 are bent thereon so as to close the open end 5a, and the bases of the continuous folds 11, 11 of the lower flaps 6, 6 and the tongue pieces are folded. Hot melt wax 18 was applied to the center of the adhesive pieces 13, 13, and upper flaps 7, 7 were bent in the same manner on top of the lower flaps 6, 6, and protruded from the tips of the upper flaps 7, 7. The tongue pieces 10, 10 are bent inward at the folds 7a, 7a, and the tongues are attached to the bottom plate 1 from the small cuts 14, 14 on the continuous folds 11, 11 to the U-shaped cuts 12, 12. Single piece 1
3, 13, and hot-melt the upper flaps 7, 7 and the tongue pieces 10, 10 to the bases of the lower flaps 6, 6 and the center parts of the tongue pieces 13, 13, thereby pasting them. As shown in FIG. 1, it is completed in a sealed state.

"Effects of the Idea" As explained in detail above, in this invention, the tongue pieces 10, 10 are provided protrudingly when cutting the paper material, and the U-shaped cuts 12, 12 are formed on the bottom plate 1 and the continuous folds 11, 11, respectively. By simply making extra small cuts 14, 14, the tongue piece sticking pieces 13, 1 can also be used in a cartoning machine.
It is only necessary to apply hot melt wax 18 to 3 and to modify the tongue pieces 10, 10 from the small cuts 14, 14 to the U-shaped cuts 12, 12, respectively. Equipment costs are lower compared to conventional equipment. Furthermore, if an attempt is made to forcefully open the package without using the opening zipper 17, the tongue piece must be cut off from the upper flap, making it easy for an untrained eye to determine that the package has been opened intentionally. .
