Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to a packaging box, and in particular, the closing flaps of a lid plate and a bottom plate that close the upper and lower openings of a box body are arranged in opposite directions in the vertical direction. It is configured so that it can be opened and closed standing up.
Furthermore, the fold-in tongue piece formed at the tip of the lid plate and the bottom plate is such that the inside of the contact piece folded back inward from the upper end of the wall surface located on the front surface to which it is fitted and the inside of the tongue piece are mutually connected. The present invention relates to a packaging box having an effective function of preventing tampering, characterized in that it is configured to be integrated with the adhesive.

[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 with front and rear walls and left and right walls, and a box is formed at both the upper and lower ends of the front wall that forms the cylindrical body. The lid plate and the bottom plate for closing the opening are arranged in a row so that they can be folded and opened and closed freely.

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 and others add mechanisms to the box body to prevent tampering or constitutional amendments. paying attention to. However, most of the structures that are used to prevent opening or constitutional amendments to these parts have a double structure on the cover plate or bottom plate, so that in the event that the seal is opened, there will be no traces of tampering. However, in this case, there is a problem that the structure is complicated, and if the glue portion is carefully opened with a sharp knife, there is no risk of damage to the lid or bottom plate. It has been pointed out that the disadvantage is that the risk of being able to remove the contents without giving them remains.

In order to fundamentally solve these problems, the applicant of the present application proposes that the M plate is located on the front side of the side where the insertion tongue portion formed at the tip of the bottom plate is folded in, as illustrated in FIG. A contact piece of a predetermined length is folded inward from the upper end of the wall surface, and the inside (back side) of the insertion tongue piece formed at the tip of the lid plate or bottom plate is placed inside the folded abutment piece. A structure was invented in which the opening was closed by adhering them together.

In the case of the invention described above, even if a paper knife or the like is inserted from the top surface of the closed lid plate to open the seal, the surface on which they slide is the back side of the adhesive surface, and the adhesive The surface is a surface that cannot be touched from the outside, which is a dramatic improvement over the conventional sealing structure, but as shown in the same figure, the insertion direction of the insertion tongue is the same for both the top and bottom. Insert an opening tool such as a long vapor knife from the lid plate side (or bottom plate side) to peel off the adhesive surface between the contact piece and the insertion tongue piece located on the opposite side. There was a problem that it could not be said that something like this would never happen, but there was some risk.

[Purpose of the invention]

The present invention seeks to address the above-mentioned problems,
A lid plate and a bottom plate formed at the upper and lower openings of the box body are configured so that the upright directions can be raised and lowered in opposite directions, and correspondingly, a tongue piece for insertion is formed at the tip of the lid plate or the bottom plate. By making the continuous wall surfaces of the contact pieces to which the top and bottom sides are opposite to each other, after the box body is assembled, the adhesive portions of the insertion tongue pieces connected to the tips of the lid plate and the bottom plate will be in the opposite direction. To completely eliminate the risk of the package being opened by an opening tool inserted from the side, and to further ensure the safety of the contents by adding functions to prevent constitutional changes and tampering after the box is assembled. The aim is to provide a packaging box that can be used in a variety of ways.

Another object of the present invention is that the other piece (closing abutment piece) to which the insertion tongue pieces connected to the tips of the lid plate and the bottom plate are inserted and attached, even when the box body is assembled. By having a structure in which it does not come into close contact with the inner surface of the folded wall surface and always maintains a constant distance between the inner surface of the folded wall surface, the wall surface of the box and the closing contact piece The insertion opening for the insertion tongue formed at the boundary part (folded part) between the folding and the insertion tongue can be kept wide open at all times, thereby making it possible to insert the insertion tongue easily and accurately. The present invention aims to provide a packaging box equipped with a mechanism.

[Summary 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 a box body made of a cylindrical body are closed by a lid plate and a bottom plate, respectively, in which the lid plate and the bottom plate are erected in opposite directions. In addition, the upper end (or lower end) of the wall surface, which is located on the front side of the side where the insertion tongue piece formed at the tip of the cover plate or bottom plate is folded, is connected to the upper end or lower end of the wall surface. A closing abutment plate is provided so as to be continuous with the wall piece constituting the body, and the closing abutment plate is folded into the inner side of the wall piece, and the end portion of the closing abutment plate is folded into the inner side of the wall piece when the body is folded and closed. The adhesive surface is formed on the back side of the insertion tongue piece connected to the tip of the M plate and the bottom plate. However, the main point is to be configured so that it can be attached to the inside of the closing abutment piece (the surface that contacts the rear wall) when it is inserted and closed.

〔Example〕

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

The box body generally indicated by A is formed so that a right side wall piece 1, a front wall piece 2, a left side wall piece 3, and a rear wall piece 4 are successively continuous via bending lines 11...11. At the upper end of the front wall piece 2, there is a cover plate piece 5 having a tongue piece 51 inserted at its tip, and at the lower end of the rear wall piece 4, a bottom plate piece 6 having an inserted tongue piece 61 at its tip can be bent freely. This is how they are connected.

The right side wall piece 1 and the left side wall piece 3 have folding pieces 12.12 and 32.32 arranged in series above and below, respectively. 2
Reference numeral 1 denotes a semi-circular notch formed with a perforation in the center of the upper end of the front wall piece 2 so that it can be peeled off. Both ends of this notch 21 are located at the boundary with the cover plate piece 5. The perforations are made to coincide with the perforation lines 52 formed by carving.

Reference numeral 41 denotes a glue margin continuous to the side end of the rear wall piece 4, which abuts on the inner side of the end of the right side wall piece 1 and is integrally bonded thereto.

7.7 is attached to the upper end of the rear wall piece 4 and the lower end of the front wall piece 2,
These are abutment plates for closing that are arranged in a row so that they can be folded freely, and the tips thereof can be attached to the central part of the back surface of the rear wall piece 4 or the front wall piece 2 via an adhesive 73, 73. That's what I do.

An insertion hole 7171 for inserting the insertion tongue pieces 51, 61 connected to the Mvi piece 5 or the bottom plate piece 6 is provided in the bent part of the closing abutment plate 7. It is desirable that an insertion guide upright piece 72 be erected in the opening 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, an insertion tongue piece 5 connected to the lid plate piece 5 and the bottom plate piece 6
The adhesive application surfaces 52 and 62 formed on the back surfaces of the closing abutment plates 7 contact and adhere to the inner surface (the surface facing the wall piece) of the closing abutting plate 7.

The box constructed as described above is constructed as follows.

Closing abutments Fi, 7 are connected to the lower end of the front wall piece 2 and the upper end of the rear wall piece 4 so that they can be bent freely.

In 7, after folding the front wall piece 2 and the rear wall piece 4 inside in advance, the adhesive 73 applied to the back side of the tip is applied to the central part of the corresponding wall surface so that the abutting plate 7 is slightly curved. (See the two-dot chain line in Figure 2)
.

In the box body pretreated in this way, the right side wall piece 1, the front wall piece 2, the left side wall piece 3, and the rear wall piece 4 are arranged along the bending lines 11...11, as in the case of assembling a known cylindrical box. After being bent sequentially along the
1 is attached to the back surface of the side end of the right side wall piece 1 to form a rectangular cylindrical body.

The cylindrical box body is obtained by folding down the folding pieces 12 and 32 that are connected to the upper and lower sides of the right side wall piece 1 and the left side wall piece 3 so as to close the openings inward, respectively, and then folding the lid plate 5. The opening is closed by the bottom plate 6. In this case, the lid plate piece 5 and the bottom plate piece 6 each have a tongue piece 5 for insertion at the tip thereof.
1 and 61 are connected, so the tongue piece 51.61
is inserted into the insertion hole 71.71 of the closing abutment plate 7, and then the adhesive coated surfaces 52 and 62, which have been applied and formed on the back side of the tongue pieces 51 and 61, are brought into contact with the back side of the closing abutment plate 7. By making it sticky, it 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) After the box is assembled, the back side (adhesive applied surface) of the insertion tongue pieces 51 and 61 connected to the tips of the lid plate piece 5 and the bottom plate piece 6 is connected to the closing abutment plate 7. .7, so even if you insert a sharp object such as a knife into the box (from the base end side where the insertion tongue is attached) for the purpose of opening the box after assembly is completed, it will not be inserted. The cutlery moved only between the back surfaces of the insertion tongues 51 and 61 and the inner surface of the rear wall surface 3, and cannot touch the adhesive coated surface at all. The box has the excellent feature that there is absolutely no risk of the box being opened, and the risk of the box being opened through the insertion tongue, which was present in conventional boxes, has been completely eliminated.

In particular, in the present invention, the connecting parts of the closing abutment plates 7.7 are not connected to the top and bottom of one wall surface, for example, from the top and bottom of the rear wall piece, as in the conventional case. One contact piece 7 is connected to the upper end of the front wall piece 2, and the other contact piece 7
are connected to the lower end of the rear wall piece 4, and the parts are connected to the diagonal lines when the box body is assembled, so that the abutting parts located on the lower end side as in the conventional case are not used. An opening operation is performed in which the adhesive part between the plate and the closing tongue is peeled off with the tip of a paper knife inserted from the upper end side, or the adhesive part on the upper end side is peeled off by the opposite operation. There will be no need to worry, and the effect of preventing constitutional amendments will be fully demonstrated.

(2) When assembling the box, the closing abutment plates 7.7 connected to the upper end of the front wall piece 2 and the lower end of the rear wall piece 3,
It is a simple operation that is exactly the same as the conventional one, except for the addition of the operation of folding each one into the inside of the wall where they are connected and gluing the tip to the center of the back of the wall. Similarly, automatic assembly can be easily performed using a cartoner.

(3) The assembled box body, especially the front wall piece 2 and the rear wall piece 4
A closing abutting plate 7 which is folded back and connected to the inside of the 7.
7 is abutting plates 7, 7 by selecting the sticking part of the application surface of the adhesive 73 applied to the tip (by making the sticking part a little higher than the center of the wall surface).
The structure is such that they abut and integrate with the center part of the back surface of the wall surface, which is the base on which they are connected, with a slight curvature. The contact plates 7, 7 as a whole exhibit a floating action with elasticity. As a result, the back side of the front wall piece 2 or the rear wall piece 4 constituting the box body and the closing abutment plate 7 Since it is possible to maintain a constant gap between them without making close contact, the insertion holes 71 and 71 portions split in the folded portions are kept open in an optimal state for inserting the insertion tongue piece 51 or 61. Therefore, insert tongue piece 51 or 6
1 will not cause any troubles such as being unable to insert it.

(4) Around the insertion hole 71 split in the bent part,
When the insertion guide upright piece 72 is erected, the above (3)
The effect can be further enhanced.

(5) Since the box body can be assembled by folding a single sheet of paper, the box body can be assembled using an automatic box making machine such as a cartoner.

(6) To open the box after sealing, as shown in FIG. However, in this case, the cover plate piece 5 cannot be closed again.
