[Prior art and its problems]

In general, the structure of a packaging box is such that the box body is formed as a square cylindrical body by front and rear walls and left and right walls, and the upper and lower ends of the front wall forming the cylindrical body are A cover plate and a bottom plate for closing an opening formed in the cover plate are arranged in series so that they can be bent and opened and closed.

Among these packaging boxes, especially when the purpose is to store drugs, etc., the packaging boxes must be opened to prevent the risk of the drugs stored inside being tampered with or the contents being extracted. It is necessary to have a prevention function.

For these purposes, pharmaceutical manufacturers add mechanisms to the box body to prevent tampering or tampering. However, in order to prevent these parts from being opened or tampered with, most of the parts have a double structure on the cover plate or bottom plate, and in the event that the seal is opened, The lid has a structure that makes it easy to see traces of opening, but in this case, there is a problem that the structure is complicated, and if the glue area is carefully opened with a sharp knife, the lid plate can be easily seen. Alternatively, it has been pointed out that there is still a risk that the contents may be taken out without damaging the bottom plate or the like.

As a fundamental solution to these problems,
Utility Application No. 61-26221 (Utility Model Application No. 61-26221)
63-13817), a packaging box equipped with a tamper-proof mechanism was devised, and the purpose was almost achieved; however, even in this case, the structural members used for its construction were There remains the inconvenience that the main body and the abutting piece that abuts the main body must be made of separate members.

[Purpose of the invention]

The present invention attempts to deal with the above-mentioned problems, and when closing with a lid plate and a bottom plate,
By configuring the surface to be adhered to which the adhesive portion of the insertion tongue connected to the tip of the lid plate and the bottom plate comes into contact and adheres as a surface that cannot be touched from the outside after the box body is assembled, We have added tamper-proofing and tamper-proofing functions to further ensure the safety of contents.
We aim to provide packaging boxes that can be guaranteed.

Another object of the present invention is that the other piece (closing abutment piece) to which the insertion tongue piece connected to the tip of the lid plate and the bottom plate is inserted and stuck can be fixed even when the box body is assembled. By making the structure so that it does not come into close contact with the wall piece and has a certain distance between it and the rear wall piece, the boundary area between the rear wall piece of the box and the closing contact piece (bending The device is equipped with a folding mechanism in which the insertion opening for the insertion tongue formed by splitting the insertion tongue can be kept wide open at all times, thereby making it possible to insert the insertion tongue easily and accurately. The aim is to provide packaging boxes.

[Key points of the invention]

In order to achieve the above-mentioned object, the present invention is characterized by adding the following structure to the structure of a known box body. That is, the present invention provides a box body configured such that both upper and lower ends of the box body made of a cylindrical body are closed by a lid plate and a bottom plate, respectively. Closing abutment plates to be folded into the inside of the rear wall piece are provided at both ends so that the two ends slightly overlap when folded and closed, and the closing abutment plates are folded and closed when folded and closed. By affixing only the overlapping parts, a certain distance can be maintained between the rear wall of the box body and the insertion tongues connected to the tips of the lid plate and the bottom plate. The main point of the surface is to be configured so that it can be attached to the inside of the closing abutting plate (the surface that contacts the rear wall) when the surface is inserted and closed.

〔Example〕

An example of implementation of the present invention will be described below with reference to the drawings.

The box generally indicated by A has a front wall piece 1, a left side wall piece 2, a rear wall piece 3, and a right side wall piece 4, which are bent along the bending line 11.
... 11, and at the upper end of the front wall piece 1 there is a cover plate piece 5 which has a tongue piece 51 inserted at the tip, and at the lower end of the front wall piece 1 there is a tongue piece 5 which is inserted at the tip and has a tongue piece 51. The bottom plate pieces 6 each having a piece 61 are arranged in a row so that they can be bent freely.
The left side wall piece 2 and the right side wall piece 4 have folding pieces 21, 21 and 41, 41 arranged in series above and below, respectively. 12 is a semi-circular notch formed with a perforation in the center of the upper end of the front wall piece 1;
Both ends of the notch 12 are aligned with a perforation line 52 formed at the boundary with the cover plate piece 5.

Reference numeral 13 denotes a glue margin continuous to the side end of the front wall piece 1, which abuts on the inner side of the end of the right side wall piece 4 so as to be integrally bonded thereto.

7, 7 are closing abutment plates that are connected to the top and bottom of the rear wall piece 3 so that they can be folded freely, and have a length that allows the tips to slightly overlap each other when folded; The overlapping portion described above can be integrally bonded by an adhesive applied to the glue margin 73.

Insertion holes 71, 71 for inserting insertion tongue pieces 51, 61 connected to the cover plate piece 5 or the bottom plate piece 6 are provided in the bent portion of the closing abutment plate 7. 71 fissure opening,
It is desirable to erect the insertion guide upright piece 72 so that when the insertion tongue pieces 51, 61 are inserted, the tips of the tongue pieces are accurately guided to the insertion hole 71.

In addition, the adhesive application surfaces 53 and 63 formed on the back surfaces of the insertion tongue pieces 51 and 61 connected to the lid plate piece 5 and the bottom plate piece 6 contact and adhere to the inner surface of the closing abutting plate 7. I try to do that.

The box constructed as described above is constructed as follows.

The closing abutment plates 7, 7, which are connected to the upper and lower ends of the rear wall piece 3 so that they can be bent freely, are folded into the inside of the rear wall piece 3 in advance, and the ends that are overlapped with each other have a glue allowance 73. (See the double-dashed line in Figure 2.) The box body pretreated in this way is assembled with the front wall piece 1 in the same manner as when assembling a known cylindrical body. , the left side wall piece 2, the rear wall piece 3, and the right side wall piece 4 are at the bending line 11.
...11, and then the glue margin 13 connected to the end of the front wall piece 1 is adhered to the back surface of the side end of the right side wall piece 4 to form a cylindrical body. do.

The cylindrical box has fold-in pieces 21 and 41 connected to the upper and lower sides of the left side wall piece 2 and the right side wall piece 4.
are folded down so as to close the openings inward, and then the openings are closed by the lid plate 5 and the bottom plate 6. In this case, the lid plate 5 and the bottom plate 6 have tongue pieces 51 for insertion at their tips. and 61 are arranged in a row, so after inserting the tongue pieces 51, 61 into the insertion holes 71, 71 of the closing abutment plate 7, the adhesive application surface coated on the back side of the tongue pieces 51, 61 is applied. By abutting and adhering the portions 53 and 63 to the back surface of the closing abutment plate 7, they can be integrated and the assembly can be completed.

〔Effect of the invention〕

The features of the present invention configured as described above are as follows.

(1) When assembling the box, it is exactly the same as the conventional method except that the closing abutment plates 7, 7 connected to both the upper and lower ends of the rear wall piece 3 are folded into the inside of the rear wall piece 3. It is easy to operate, and can be easily assembled automatically using a cartoner, similar to conventional assembling packaging boxes.

(2) The closing abutment plate 7, which is folded back and connected to the inside of the assembled box body, especially the rear wall piece 3,
7 has a structure in which the overlapping portions of both ends extending from the top and bottom are adhered and integrated with each other, and the rear wall piece 3
Since means such as adhesion to the box body are eliminated, the closing abutment plates 7, 7, whose overlapping parts are bonded and integrated, have an elastic lifting effect as a whole, and as a result, the box body The rear wall piece 3 and the closing abutment plate 7 do not come into close contact with each other, and a constant gap can be maintained between them, so the insertion holes 71, 71, which are split in the bent part, are ideal for insertion. Since the opening is maintained in this state, troubles such as inability to insert the closing tongues 51, 61 will not occur when inserting them.

(3) The effect of the above (2) can be further enhanced when the insertion guide upright piece 72 is made to stand up around the insertion hole 71 which is split in the bent portion.

(4) After completing the assembly, the box body has an insertion tongue piece 5 connected to the tip of the cover plate piece 5 and the bottom plate piece 6.
1, 61 (adhesive applied surface) is configured so that it comes into contact with the back surface of the closing abutment plates 7, 7, and is glued to the box after assembly is completed (the mounting base of the insertion tongue piece). Even if a sharp blade such as a knife is inserted for the purpose of opening the package (from the end side), the inserted blade only moves between the back of the insertion tongues 51, 61 and the inner surface of the rear wall surface 3, It has the excellent feature that the surface where the adhesive is applied cannot be touched at all, so there is absolutely no risk that the box will be opened after being sealed.
The risk of the box being opened from the insertion tongue portion, which the conventional box had, could be completely eliminated.

(5) The above-mentioned prior invention of the applicant
