The following packaging box disclosed in No. 61-113218 is known.

That is, as shown in FIG. 10, the side plate A1,
The outer upper plate B, the side plate A2, the bottom plate D, the side plate A3, the inner upper plate E, and the pasting piece F are arranged horizontally through each fold, and the front and rear sides of the side plates A1, A2, and A3 are provided with folds interposed therebetween. A tongue piece C is connected to the front and rear sides of the bottom plate D, and a side plate H having a tongue piece J is connected to the front and rear sides of the bottom plate D through each fold, and a tongue piece K is connected to the front and rear sides of the inner upper plate E through each fold. This is made into a flattened box by stacking the outer upper plate B so that the inner upper plate E is on the inside, and gluing the pasting piece F to the side plate A2, and gluing the side plate A1 to the side plate A3. Then, after converting this into a three-dimensional form and storing the object to be packaged, each tongue piece C and tongue piece K are bent, and the side plate H and the tongue piece K of the inner upper plate E are adhered, and the inner and outer upper plates are A packaging box is disclosed in which a tongue piece J is inserted between B and E and bonded together.

(Problem to be solved by the invention) However, in this packaging box, it is possible to sequentially peel off the adhesive from the adhesive part between side plate A1 and side plate A3 and the adhesive part between side plate H and tongue piece K without tearing the paper. Because of this configuration, it was not possible to sufficiently prevent the insertion of foreign substances such as poisonous substances and the extraction of contents.

In addition, when assembling into the box, the inner and outer upper plates B and E
Since the panels are stacked without forming a space, it is difficult to insert the tongue J between the inner and outer upper plates B and E, making it difficult to assemble the box.

The present invention provides a tamper-proof paper box that is easy to assemble, in which it is impossible to take out the contents by peeling off the adhesive part without tearing the paper, preventing the insertion of foreign substances such as poisonous substances, and the extraction of the contents. The purpose is to

(Means for Solving the Problems) In order to achieve the above object, the tamper-proof paper box of the present invention has a rear wall, a side wall, a front wall, a side wall, and a rear inner wall that are connected laterally through folds. The rear wall and the rear inner wall of the body forming wall forming the box body with both ends open are overlapped to form a double wall, and the lid is connected to the upper and lower sides of the front wall opposite to the double wall. and a paper box in which the openings at both ends are closed by flap pieces connected to the upper and lower sides of each side wall, and an insertion piece connected to the lid is inserted between the double walls and bonded, The insertion piece is made narrower than the lid width, and an inner lid piece with an insertion hole into which the insertion piece is inserted is connected to the rear wall which is the outside of the double wall, and the inside of the double wall. A concave portion having a depth approximately equal to the thickness of the insert piece is formed on the rear inner wall on which the insert piece overlaps, and tamper-preventing flap pieces are connected to the upper and lower sides of the side wall. In addition, an outer wall with one flap side connected to the upper and lower sides is connected to the rear wall, and the side outer wall and its flap piece are overlapped with the outer surface of the side wall adjacent to the rear inner wall and the flap piece for adhesion. It was designed to be worn.

(Example) Next, an example of the tamper-proof paper box according to the present invention will be described with reference to FIGS. 1 to 9.

FIG. 1 is a back view of the box in its unfolded state, showing the side outer wall 1, the rear wall 2, the side wall 3a, the front wall 4, which forms the trunk forming walls.
The side wall 3b and the rear inner wall 6 have each fold a, b, c, d,
The slit e1 is formed in a continuous manner in the lateral direction via e, and in particular, a slit e1 is formed on the fold e portion which becomes the inside of the fold a when assembling the box, so as not to put too much pressure on the fold a portion.
has been opened.

On the upper and lower sides of the rear wall 2, inner lid pieces 8 each having an insertion hole 7 for inserting an insertion piece 10 described later are arranged in series along the fold f, and on the upper and lower sides of the front wall 4. In this case, a lid 11 in which an insertion piece 10 to be inserted into the insertion hole 7 is connected to the perforation line y is connected to the lid 11 through a fold line h, and is aligned with one of the fold lines h and placed in the center. An opening line 12 consisting of a perforation line slightly inserted into the front wall 4 side is provided.

In addition, flap pieces 9 are connected to the upper and lower sides of the side outer wall 1 and the side wall 3a through the fold g on one side and the perforation line _z on the other side, and on the upper and lower sides of the side wall 3b, the lid 11 of the front wall 4 A narrow tamper-proofing flap piece 13 is provided adjacent to the flap piece 13 via a break line x which also serves as a fold.

Further, on the upper and lower sides of the rear inner wall 6, on which the insert piece 10 is superimposed and bonded when assembling the box, a concave portion 1 is recessed to a depth approximately equal to the width of the insert piece 10 and the thickness of the insert piece.
4 is formed, and a guide piece 1 whose width is slightly wider than the insertion piece width is formed through the fold i along the upper and lower sides of the rear inner wall 6.
5 are arranged in a row, and slight cut lines 16 are formed at the bases on both sides of the guide piece 15.

The unfolded product of the tamper-evident paper box according to the present invention having the above structure is obtained by folding the fold d into the state shown in FIG. 3 from the unfolded state shown in FIG. The adhesive S1 is applied on the blocking flap piece 13, and at least the rear inner wall 6 is coated with the adhesive S1.
After applying adhesive S2 to the left and right or free end side edges or left and right side edges of the By polymerizing and gluing them together, a flat box with a double wall on the front wall and one side wall is completed.

This flat box is transported and stored as is, and is finally assembled when storing objects.

That is, the side outer wall 1 and the side wall 3a on which the side wall 3b is attached are erected from the flat state shown in FIG.
As shown in the figure, a box body P with both ends open is formed and assembled from the bottom in the figure.

First, fold the lower inner lid piece 8 inward, and at the same time,
The guide piece 15 overlapped with the inner cover piece 8 is folded in to close the box opening surface.

At this time, since there are slight cut lines 16 (see Fig. 1) at the bases on both sides of the guide piece 15, the guide piece 15 is bent at creases i and i' (see Fig. 1 or 8). As shown in the cross-sectional view of the figure, the space between the fold i and the fold i' forms a slope, making it easier to insert the insertion piece 10 into the concave surface portion 14.

Next, the flap piece 9 to which the tamper-proofing flap piece 13 is attached is first bent, and then the other flap piece 9 is folded over the inner lid piece 8, and adhesive S3 is applied to at least the inner surface of the insert piece 10. After coating the lid 11, bend the lid 11, insert the insertion piece 10 through the insertion hole 7 of the inner lid piece 8, and adhere it to the concave part 14 recessed from the adhesive surface of the rear inner wall 6 and the rear wall 2. Then close the bottom and make the condition shown in Fig. 6.

After storing the object into the box body through the upper opening, the upper opening is closed in the same manner as the bottom, thereby completing the tamper-proof paper box (see FIG. 7).

FIGS. 8 and 9 show enlarged cross-sectional views of the tamper-proof paper box with the lid closed in this manner.

As is clear from this figure, the insertion piece 10 connected to the lid 11 is inserted through the insertion hole 7 of the inner lid piece 8 connected to the rear wall 2, and the overlapping surface of the rear wall 2 and the rear inner wall 6 An adhesive portion is formed on the concave surface portion 14 different from the lateral wall 1 and the side wall 3b, and a tamper-preventing flap piece 13 is adhered to the flap piece 9 when the side outer wall 1 and the side wall 3b are bonded together. Since the adhesive portion is formed so that the adhesive surface is not exposed, it cannot be removed with a sharp knife or the like unless the tamper-proofing flap piece 13 and the insertion piece 10 are cut.

When the tamper-proof paper box with the lid closed in this manner is normally opened, the lid 1 is broken by pushing the opening line 12 of the front wall 4 with a finger and breaking it along the perforation line z and the tear line x.
1 is opened by pulling it upward.

Although the flap piece 13 for preventing tampering is narrow in the embodiment, it may be made wider or may have the same shape as the flap piece 9.

In the above embodiment, the lid 11, the flap piece 9, and the insertion piece 10 were explained as being connected to each other along the perforation lines y and z, but it is also possible to connect them along the end folds. Needless to say.

(Operations and Effects of the Invention) The tamper-evident paper box according to the present invention configured as described above has both ends secured by the rear wall, side wall, front wall, side wall, and rear inner wall that are connected in the transverse direction through folds. The rear wall of the trunk forming wall forming the open box trunk and the rear inner wall are overlapped to form a double wall, and a lid and each side wall are connected to the upper and lower sides of the front wall opposite to the double wall. In the paper box, the openings at both ends are closed by flap pieces connected to the upper and lower sides, and an insertion piece connected to the lid is inserted between the double walls and bonded, wherein the insertion piece The inner cover piece is made narrower than the cover width and has an insertion hole into which the insertion piece is inserted, and is connected to the rear wall that is the outside of the double wall, and the rear inner wall that is the inside of the double wall. A concave portion having a depth approximately equal to the thickness of the insert piece is formed on the surface on which the insert piece is overlapped, and tamper-preventing flap pieces are provided in series on the upper and lower sides of the side wall, and further The outer wall having flap pieces connected to the upper and lower sides is connected to the rear wall, and the side outer wall and its flap pieces are attached heavily to the outer surface of the side wall adjacent to the rear inner wall and the flap piece for sticking. The insertion piece connected to the lid is inserted through the insertion hole of the inner lid piece connected to the rear wall, and an adhesive part is formed on a concave surface different from the overlapping surface of the rear wall and the inner wall, When adhering the side outer walls to the side walls, a tamper-proofing flap piece is adhered to the flap piece, so that an adhesive part is formed between the side outer walls and the side walls so that the adhesive surface is not exposed.

For this reason, even if the bond between the side outer wall and the side wall can be peeled off with a thin knife without being noticeable, the seal cannot be opened unless the tamper-evident flap piece is cut. Even if it were possible, it would not be possible to remove the insertion piece without damaging it, so insertion of foreign substances such as poisonous substances and extraction of contents can be effectively prevented.

In addition, the tamper-proof paper box according to the present invention has a recessed portion having a depth approximately equal to the thickness of the insert piece on the inner wall of the double wall, on which the insert piece overlaps. The opening for inserting the insert piece between the walls is now open, making it easier to insert the insert piece.

Therefore, according to the present invention, it is possible to easily assemble the box, and it is possible to provide a tamper-proof paper box in which it is impossible to insert foreign objects such as poisonous substances or remove the contents without tearing the box paper. .
