Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a packaging box, and in particular, a method for preventing the box body from being subjected to a number-setting after being sealed, or for preventing the box body from being sealed after being sealed. This invention relates to a packaging box that is equipped with a mechanism that can prevent unauthorized opening of the packaging box.

[Prior art and its problems]

Generally, packaging boxes have a structure in which the box body is formed into a square cylindrical body with front and rear walls, left and right walls, and upper and lower openings are formed at both upper and lower ends of the rear wall that forms the cylindrical body. The structure was such that a lid plate and a bottom plate were continuously formed to close the area.

When packaging boxes are used for the purpose of storing drugs, etc., they must be used to prevent the risk of the drugs stored inside the box being tampered with or the contents being extracted. Therefore, it is desired that the box has a function that can prevent unauthorized opening operations.

In order to achieve this purpose, drug manufacturers have added mechanisms to the box body to prevent unauthorized opening operations when constructing packaging boxes. The mechanisms are mainly concentrated in the lid and bottom plate parts, where unauthorized opening operations are most likely to occur.

However, in most cases, the measures conventionally adopted to prevent unauthorized opening or tampering with the lid plate or bottom plate are to double-layer the lid or bottom plate. However, in the event that the package was opened, traces of tampering would be easily visible.However, there were manufacturing problems in that the structure was complex to achieve the purpose. If other parts other than the lid plate or bottom plate, such as the glue margin, are carefully opened with a sharp knife, the contents can be taken out without damaging the lid or bottom plate. It has been pointed out that the drawback is that the risk of this still remains.

In order to solve these drawbacks, the present inventor proposed a packaging box having a mechanism to prevent unauthorized opening and having the following structure. That is, (1) a cover plate and a bottom plate each having an adhesive tongue piece at the tip thereof are arranged in a row on the upper and lower sides of the rear wall surface of the box body formed in a cylindrical shape, so that the cover plate and the bottom plate can be bent freely, and the cylindrical shape is To be able to close the upper and lower openings of the body.

(2) Folding pieces of a fixed length are installed on the top and bottom of the front wall of the cylindrical box, and these folding pieces are folded into the inside of the cylindrical box to fit almost tightly to the inner surface of the front wall. make contact as shown. (Construct so that the upper and lower ends of the front wall surface have a double structure.) (3) Form a double wall surface on the inside of the front wall piece. An opening (a striped gap) is formed at the boundary between the cover plate and the fold-out piece, into which an adhesive tongue piece connected to the tip of the cover plate or the bottom plate is inserted.

(4) When assembling the box, apply adhesive to the back side of the adhesive tongue attached to the lid plate or bottom plate (in ordinary packaging boxes, adhesive is applied to the front side of the tongue), The adhesive applied surface is adhered to the inner side of the folded piece (the surface in contact with the front wall) located on the corresponding surface.

(5) As a result of the back surface of the tongue piece being adhered to the inside of the folding piece, the adhesive applied surface cannot be touched from the outside at all.

That is the structure.

In the case of the structure described above, it was significantly superior to the structure of conventional packaging boxes in that it had a high probability of preventing unauthorized opening. The folding piece is extended to the upper and lower ends of the opposite structural part for inserting the piece, that is, the front wall piece (
Because the structure of the box is complicated, it forms an opening surface (a striped opening surface) into which the tongue piece is inserted at the bending boundary between the folding piece and the front wall piece. It requires special technology to assemble, and automatic assembly using existing cartoning machines is impossible, and if the assembly work is to be automated, a new assembly mechanism must be installed, resulting in higher costs. I had a problem.

In addition, in the case of the above structure, even if the opening operation device is inserted from the lid plate, the insertion site is on the front side of the lid plate, so it cannot touch the adhesive applied to the back side of the lid plate. However, if the insertion tongues formed at the ends of the lid plate and the bottom plate are formed in the same direction, insert a sharp knife etc. from the lid plate side and insert it into the bottom plate side located on the opposite side. It is possible to perform an unauthorized opening operation by peeling off the adhesive applied to the back side of the insertion tongue, which is still not perfect. [Objective of the Invention] The present invention ζ Although the structure is simple, it is difficult to touch the closing adhesive surface from the outside when the lid plate and bottom plate of the assembled box are closed. It is an object of the present invention to provide a packaging box having a mechanism to prevent unauthorized opening.

Another object of the present invention is that mechanisms for preventing number entry are provided at multiple locations inside the box, so that in the unlikely event that an unauthorized opening operation is performed, there will be no trace of the opening operation inside the box. The box is constructed so that the contents remain and can be easily checked, thereby ensuring the safety of the contents contained in the box and providing a mechanism to prevent unauthorized opening, which enables more thorough management of the contents. The purpose is to provide boxes for packaging.

[Summary of the Invention] The present invention forms a rectangular cylindrical box body by folding a sheet of paper having an appropriate thickness, and at both upper and lower ends of the front wall surface constituting the box body, In a packaging box in which a lid plate and a bottom plate are arranged in a bendable manner, the rear wall and the left side wall portion of the box body are configured as a double wall surface, and the double wall surface is configured. Of the rear wall surface, the inner wall piece is separated at the center in the height direction to form two upper and lower inner rear wall pieces, and these two separated inner rear wall pieces and outer wall pieces are separated. are glued and integrated at the separated parts of the inner rear wall piece, and then form an adhesive application surface on the upper and lower ends of the inner rear wall piece, and apply this application surface to the tips of the lid plate and bottom plate. The main point of the invention is a packaging box equipped with a mechanism to prevent unauthorized opening, which is configured to be integrated with the back surface of an insertion tongue formed in the box.

〔Example] Embodiments of the present invention will be described below with reference to the drawings.

The packaging box of the present invention is composed of a piece of paper having an appropriate thickness, and includes a box body formed into a cylindrical shape by folding, and a closing mechanism that closes the upper and lower openings of the box body. It is composed of.

The box body has 1 left outer wall piece, 2 rear outer wall pieces, 3 right wall pieces, and 4 front wall pieces.

Reference numeral 7 denotes a cover plate, and 8 a bottom plate, which are arranged in series so that both the upper and lower ends of the front wall piece 4 can be bent freely, and insert tongue pieces 7a and 8a are arranged in series at the tip thereof so that they can be bent freely. has been done.

9...9 are closing pieces that are bendably connected to both the upper and lower ends of the left outer wall piece 1, the right wall piece 3, and the rear inner wall piece 5, and when the box body is assembled into a cylindrical shape, the upper and lower ends thereof are closed. ↓This is for closing the opening surface that is formed.

Note that the closing piece 9 formed at the upper end of the left outer wall piece 1 has an insertion tongue piece 91 that is used when opening the packaging box, and this insertion tongue piece 91 is connected to the upper end of the right wall W3. A slit 924 for insertion formed in the provided closing piece 9 can be inserted into the insertion slit 924.

Reference numerals 21 and 21 denote notches formed at both upper and lower ends of the rear outer wall piece 2, and are formed in a wide U-shape or a concave shape similar to a construction method.

The above-mentioned notches 21, 21 are used to form adhesive application surfaces 61° 61 at both upper and lower ends of the rear inner wall piece 6 located on the back side of the rear inner wall piece 6, and are used to form adhesive application surfaces 61° 61 for the box body (box trunk). Even after the adhesive is formed into a shape, the adhesive can be easily applied by using the cutouts 21, 21.

51 is an adhesive application surface formed at the end of the left inner wall piece 5;
62. 62 is the adhesive application surface formed on the rear inner wall pieces 6a, 6a, and the adhesive application surface 51 formed on the edge of the left inner wall piece 5 is applied to the back edge of the left outer wall piece 1. In addition, the adhesive application surfaces 62 and 62 applied near the separation boundary between the two rear inner wall pieces 6a and 6a, which are separated into two pieces, are bonded and integrated with the back surface of the rear outer wall piece 2. By doing so, a rectangular cylindrical box body is formed.

(Assembling the box) The packaging box of the present invention constructed as described above is assembled as follows.

The paper pieces configured as described above are folded in order from the rear inner wall piece 6 side to the left inner wall piece 5, the front wall piece 4, the right wall piece 3, the rear outer wall piece 2 and the left outer wall piece 1, and then folded into a rectangular tube. As the assembly progresses, the rear inner wall piece 6 is located inside the rear outer wall piece 2, and the left inner wall piece 5 is located inside the left outer wall piece l, and only these parts are assembled. each form a double wall.

In this case, the adhesive application surface 51 formed at the end of the left inner wall piece 5 is bonded and integrated with the back end of the left outer wall piece 1, and the adhesive is applied near the separation boundary between the rear inner wall pieces 6a, 6a. The coated surfaces 61,61 of the applied adhesive are bonded and integrated with the back surface of the rear outer wall piece 2 to maintain the shape of the box body.

After the cylindrical box body is formed by the above operation, the closing pieces 9.9 connected to the lower ends of the right wall piece 3 and the left side wall piece 1 are then placed so that their tips overlap each other. Then, the closing piece 9 connected to the lower end of the rear inner wall piece 6 is bent onto the upper surface thereof and overlapped.

After these operations are completed, the bottom plate 8 connected to the lower end of the front wall piece 4 is bent, and the insertion tongue piece 8a connected to the tip thereof is inserted so that the rear outer wall piece 2 and the rear inner wall piece 6 overlap. Insert it into the gap.

The tongue piece 8a inserted into the above-mentioned gap has a back surface 6I formed on the end of the rear inner wall piece 6, which is coated with adhesive.
They overlap and come into contact with each other, and the two are bonded and integrated, and the closing of the bottom plate 8 is completed.

Further, after the articles are stored in the box body, the lid plate 7 is closed, and these closing operations are completely similar to the closing operations of the bottom plate 8.

For convenience of explanation, the closing operation of the bottom plate 8 and the closing operation of the lid plate 7 have been explained separately, but when performing automatic packaging using a cartoning machine, it is necessary to The formation of the parts and the closing of the bottom plate and cover plate are performed at the same time.

〔Effect of the invention〕

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

(1) - The box body is formed into a rectangular tube shape by sequentially folding pieces of paper, and a left inner wall piece 5 is located inside the left outer wall piece 1, which is the folded end of the paper pieces. Since it has a wall structure, even if you can easily open the adhesive-applied surface 51 that connects the two with a knife or the like, there is a left inner wall piece 5 inside it, so unless this is damaged, the box will not open. It is extremely safe as the items inside the main body cannot be touched, and can effectively prevent unauthorized opening operations.

(2) Lid plate 7 and bottom plate 8 that close both upper and lower ends of the box body
The back surfaces of the insertion tongue pieces 7a and 8a come into contact with the adhesive coated surfaces 61, 61 formed at the ends of the rear inner wall piece 6, so that the two pieces are bonded together. Even if a knife or the like is inserted from the surface side of 7a, 8a, it is impossible to touch it, and in this respect, the tamper-proofing function can be fully exhibited.

(3) In addition, if the insertion tongues 7a and 8a connected to the lid plate 7 and the bottom plate 8 are formed so as to face the same direction (such a closing structure is usually called a straight type). ] It is possible to perform an unauthorized operation in which the adhesive part on the back side of the tongue piece 8a located on the opposite side is opened using a knife inserted from the back side of the tongue piece 7a connected to the tip of the lid plate 7. , the present invention has a structure in which the rear inner wall piece 6 is separated into two rear inner wall pieces 6a, 6a by cutting off the middle part in the height direction by an appropriate width, and the separated two rear inner wall pieces 6a. , 6a, the adhesive application surfaces 61° 61 formed near the separation boundaries of the rear outer wall pieces 2 are bonded and integrated, so that if the lid plate 7
Even if a knife or the like is inserted from the side to unseal the surface 61 of the adhesive applied to the rear inner wall piece 6a on one side, the knife or the like that passes through it will damage the other rear inner wall piece 6a located below. The adhesive part can be expected to have the effect of preventing its intrusion. Therefore, even if the adhesive-applied surface 61 of the rear inner wall piece 6a located above is opened, the knives used for the opening operation will be guided into the inside of the box body from the cutout located below. The other rear inner wall piece 6a
It is extremely difficult to peel off the adhesive part, and even in the case of a packaging box that adopts a straight type closing structure, it can have the effect of preventing unauthorized opening operations.
