Description

  The present invention relates to a box with an unauthorized opening prevention function.

  For example, various types of packaging boxes that are sold by accommodating products such as patches are provided with a function for preventing unauthorized opening. This is intended to prevent unauthorized opening by a third party and to provide a sense of security to the purchaser so that the fact can be recognized at a glance even if it is illegally opened. It is a thing.

The tamper-evident prevention box disclosed in Patent Document 1 enables easy and strong sealing without using an adhesive.
A fitting piece 30 is formed between the two crank-shaped cuts 35 at the center of the upper end of the front side wall plate 12. On the other hand, a knob piece 27 including a cut line 24 is formed in the insertion piece 16 provided continuously with the upper cover plate 17. When the upper cover plate 17 is closed so that the fitting piece 30 formed on the front side wall plate 12 is inserted into the cut line 24, the engaging portion 31 of the fitting piece 30 and the engaging portion 32 of the insertion piece 16 are provided. Are engaged and cannot be removed, thereby preventing unauthorized opening.

Utility Model Registration No. 3092497

However, in the tamper-evident prevention box disclosed in Patent Document 1, as is clear from FIG. 3 in Document 1, the connecting portion between the fitting piece 30 and the cutting line 24 is the front side wall plate 12. Since it is exposed on the surface, it becomes possible to directly access the connecting portion from the outside. In other words, even though the connecting portion is in an unextractable state, direct access is possible, so that it is relatively easy for a malicious third party to open it.
Moreover, when sealing this tamper-evident prevention box, it is necessary to insert the fitting piece 30 formed in the front side wall plate 12 into the cutting line 24. The cutting line 24 is a flat sheet-like insertion piece. 16 has a problem that it is difficult to insert.

  An object of the present invention is to provide a tamper-evident box that has been devised in order to effectively solve such a conventional problem and is more difficult to open by a malicious third party. A further object of the present invention is to provide a tamper-evident prevention box that can be more easily sealed by closing the box.

In the box of the present invention, at least one of both open ends of the cylindrical peripheral wall is closed with a flap-shaped closing lid extending from the cylindrical peripheral wall. The closing lid includes an opening closing portion and an insertion flap that extends from the opening closing portion and is inserted into the box. The insertion flap is formed on the insertion flap with first engagement cuts formed on both sides of the base.
Moreover, the sheet | seat material is arrange | positioned along the cylindrical surrounding wall inner surface in which the insertion flap of a closing lid is inserted, The insertion port in which an insertion protrusion piece is inserted is provided in the said sheet | seat material. A second engagement cut extending outward is formed at both ends of the insertion port.
When the insertion protrusion is inserted into the insertion opening and the closing lid is closed, the first and second engagement cuts engage with each other to maintain the closed state, thereby preventing unauthorized opening by a third party.

In the box with an unauthorized opening prevention function of the present invention having the above-described configuration, the first and second engagement cuts can be engaged with each other and the closed state can be maintained simply by inserting the insertion protrusion into the insertion port. Therefore, unauthorized opening can be prevented without closing the closed portion with an adhesive or the like.
Furthermore, since the insertion port is provided in the sheet material existing inside the box (that is, no insertion port is provided in the peripheral wall surface exposed to the outside), the closed portion is directly accessed from the outside. It is not possible. Therefore, since the operation of tampering with opening this is very troublesome, it becomes difficult for a malicious third party to open the store in a short time in the store, and the crime prevention effect is high.

In the box of the present invention, it is preferable that the sheet material includes a raised portion that protrudes inward of the box in a region corresponding to the insertion protrusion inserted into the insertion port. Moreover, it is preferable that the said cylindrical surrounding wall is provided with the protruding part which protrudes toward the box outward in the area | region corresponding to the insertion protrusion inserted in the insertion port.
When such a configuration is adopted, it is easy to insert the insertion protrusion into the insertion port, which is advantageous when considering application to an automatic assembly line by a machine.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of a box 10 according to an embodiment of the present invention. FIG. 2 shows a blank 10 ′ used for manufacturing the box body 10. That is, when the blank 10 'formed by punching is assembled, the box 10 is obtained. The box 10 includes a rectangular cylindrical peripheral wall composed of four wall portions 11a to 11d.

A flap-shaped closing lid 20 is connected to the upper end of the peripheral wall 11b via a crease 100. The closing lid 20 includes an opening closing portion 21 and an insertion flap 22.
The opening closing part 21 is configured in a quadrangular shape corresponding to the shape of the upper opening of the peripheral walls 11a to 11d.
The insertion flap 22 is connected to the opening closing portion 21 through the crease 101 and has an insertion protrusion 25. The insertion protrusion 25 is inserted into an insertion port 31 described later to prevent unauthorized opening of the box 10.

On the other hand, a folding piece 30 is connected to the upper end of the wall portion 11d through a folding line 105. The folding piece 30 is folded back on the wall portion 11d and extends to the inside of the box body 10 (see FIG. 1).
An insertion port 31 is formed in an area located inside the box of the folding piece 30. As will be described in detail later, the insertion protrusion 25 of the insertion flap 22 is inserted into the insertion port 31 to maintain the closed state, thereby preventing unauthorized opening by a third party.
A hanging hole 35 is formed in a region of the folding piece 30 protruding outside the box. That is, the box 10 is displayed in a suspended state at a sales store such as a convenience store or a department store.

≪Mechanism to prevent unauthorized opening≫
When the insertion projecting piece 25 is inserted into the insertion port 31 and the closing lid 20 is closed, they are engaged and the closed state is maintained. This will be described in detail with reference to FIGS.

FIG. 3 shows an enlarged view of the insertion protrusion 25 provided on the insertion flap 22 in FIG. Cuts 26 are made in the base portions on both sides of the insertion protrusion 25. The innermost portion of the cut 26 extends substantially parallel to the ruled line 101, and this portion constitutes the first engagement cut 26a.
On the other hand, FIG. 4 shows an enlarged view of the insertion port 31 formed in the folding piece 30 in FIG. The insertion protrusion 25 is inserted into the insertion port 31. The insertion port 31 is an elongated rectangular opening extending in the lateral direction, and second engagement cuts 31a extending outward are formed on both sides thereof.

FIG. 5 is a schematic view of the state where the tip of the insertion protrusion 25 is partially inserted into the insertion port 31 when the closing lid 20 is closed in the direction of arrow A in FIG. It shows.
In FIG. 5, the first engagement cut 26 a formed at the base of the insertion protrusion 25 and the second engagement cut 31 a extending outward from the insertion port 31 are shown in an enlarged manner. .
A first engagement surface 26b facing upward in the figure is formed in the portion of the first engagement cut 26a. The surface 26b is a surface that expands in the thickness direction of the blank 10 ′ constituting the box body 10. On the other hand, the second engagement cut 31a is formed with a second engagement surface 31b facing downward in the drawing. In a state in which the insertion protrusion 25 is completely inserted into the insertion port 31 (FIG. 6), the insertion protrusion 25 is prohibited from coming out by contacting both the engaging surfaces 26b and 31b. That is, the closed state is maintained. This will be described with reference to FIG.

FIG. 6 shows a state in which the insertion protrusion 25 is completely inserted into the insertion port 31. Since the entire width of the insertion port 31 including the engagement cut 31 a is substantially equal to the entire width of the insertion protrusion 25 including the engagement cut 26 a, the insertion protrusion 25 is completely inserted into the insertion port 31. As shown in FIG. 6 in an enlarged manner, the first engagement surface 26b formed by the first engagement cut 26a and the second engagement surface 31b formed by the second engagement cut 31a , Are located facing each other in the vertical direction.
Therefore, even if a force acts in the direction in which the insertion protrusion 25 is extracted, the extraction is prohibited when the first engagement surface 26b and the second engagement surface 31b come into contact with each other. 5 and 6, only the engagement mechanism at the left end of the insertion protrusion 25 and the insertion port 31 is shown in an enlarged manner, but similar engagement is also performed at the right end. Done.

  Note that the enlarged portion in FIG. 6 shows only the main part of the engagement portion taken out, but the first engagement surface 26b and the second engagement surface 31b enlarged in FIG. Corresponds to the enlarged view in FIG.

  In order to forcibly open the engaging portion formed as described above, the insertion flap 22 or the folding piece 30 must be partially broken. Moreover, the insertion port 31 exists inside the box. That is, since the insertion port 31 is formed in the folding piece 30 extending along the inner side of the rear wall portion 11d of the box body 10, as illustrated in the rear perspective view of FIG. And the insertion protrusion 25 cannot be visually recognized from the outside of the box. For this reason, the engaging part cannot be directly accessed from the outside of the box body 10, and the operation of prying out becomes more difficult.

  That is, even if the tampering is attempted at the store, it is difficult to pry open and it takes time, and as a result, the crime prevention effect can be enhanced.

  As can be seen from FIG. 2, the bottom wall 19 of the box 10 is configured with a normal insertion bottom that is continuously provided via the folding line 103, but the same as described above also applies to the bottom wall. A tamper-evident prevention mechanism can be employed, and the crime prevention effect can be further enhanced.

≪Easy insertion by lifting up≫
As described above, in the box 10 of the present invention, the insertion protrusion 25 is inserted into the insertion port 31, but the insertion port 31 is formed in the sheet-like folding piece 30, and so on. The insertion protrusion 25 is inserted into the insertion slot 31 while sliding along the sheet surface. In that case, in order to make the insertion work simple and reliable, in the present invention, it is preferable to use a bulge (protrusion). FIG. 8 is a schematic diagram for explaining the protrusion (the raised portion).

FIG. 8A is a diagram corresponding to FIG. 4, and illustrates a case where the raised portion 38 is provided on the folding piece 30. A raised portion 38 is formed in a region below the insertion port 31 formed in the folding piece 30 (that is, a position corresponding to the insertion projection piece 25 inserted into the insertion port 31). The raised portion 38 is raised so as to protrude toward the inside of the box.
Since the insertion protrusion 25 is inserted into the insertion port 31 from the upper side in FIG. 8A, it is easy to understand that the insertion work is simple and reliable due to the presence of such a raised portion 38. it can.

FIG. 8B illustrates a case in which the raised portion 18 is provided on the wall portion 11d, and the raised portion 18 is raised toward the outside of the box.
The raised portion 18 is located just behind the raised portion 38 in FIG. That is, as can be seen from FIG. 1, the folded piece 30 is folded on the wall portion 11 d, but at this time, the raised portion 38 is positioned so as to overlap the raised portion 18.

In FIG. 2, the positions on the blank 10 ′ where the raised portions 38 and 18 are provided are indicated by hatched areas. It can be seen that when the folded piece 30 is folded back onto the wall portion 11d, both overlap.
By providing the raised portions 38 and 18 as described above, the insertion work when sealing the box is facilitated, and application to an automatic assembly line by a machine is also facilitated.

A method of providing the raised portions 38 and 18 in the box 10 is as follows. That is, by providing a corresponding raised portion on the template used for the punching of the blank 10 ′ shown in FIG. 2, the raised portions 38 and 18 can be formed simultaneously with the punching. Both of the raised portions 38 and 18 may be provided, or only one of them may be provided.
In FIG. 8A and FIG. 8B, the raised portions 38 and 18 are exaggerated and drawn so as to protrude greatly for easy understanding.

≪Modification≫
In the present invention, it is sufficient that the insertion port 31 for inserting the insertion protrusion 25 is present inside the box so that it cannot be directly accessed from the outside. Accordingly, it is not always necessary that the insertion port 31 is formed in the folding piece 30 as shown in FIG.
In the modification shown in FIGS. 9 and 10, the folding piece 130 in which the insertion slot 131 is formed is folded into the box, unlike the folding piece 30 in FIG. 1. .

FIG. 10 is a rear perspective view showing the box 110 closed with the rear wall 111d located on the other side of the page in FIG. 9 facing forward. Also in the box 110, it can be seen that the engagement portion between the insertion protrusion 25 and the insertion port 131 cannot be directly accessed from the outside.
As shown in FIG. 10, the box 110 does not have a portion protruding upward from the box in the closed state, and does not include the hanging hole 35 as shown in FIG. 1. That is, the box 110 is not displayed in a suspended state, but is displayed side by side on a shelf or the like.
As described above, the tamper-evident prevention mechanism according to the present invention can be applied to both a box that is hung and displayed and a box that is placed and displayed. In this respect, it is more advantageous than the conventional example of Patent Document 1 that can be applied only to a type of box that is placed and displayed.

The structure of the insertion protrusion 25 and the insertion port 131 itself is not different from that already described with reference to FIGS. 1 to 8, and the mechanism for maintaining the closed state and preventing unauthorized opening is also described above. Is the same as
Therefore, although not shown, it is preferable to provide a bulge (protrusion) similar to that described in FIG.

  In addition to the examples shown in FIGS. 9 and 10, for example, the same applies to the case where an individual sheet material is arranged in the box (not shown) and an insertion port is formed in the sheet material. An effect can be obtained.

≪Example of providing a window (opening) 135 for confirming the presence of the inserted insertion protrusion 25 ≫
FIG. 11 is a rear perspective view corresponding to FIG. 10 and shows an example in which a window (opening) 135 is provided in the rear wall portion 111d of the box. The box is sealed by inserting the insertion protrusion 25 into the insertion port 131. However, by providing the window 135, it can be confirmed that such insertion has been performed satisfactorily.
For example, if the portion of the insertion protrusion 25 exposed from the window 135 is colored, this confirmation can be made at a glance. As the color, a color that is conspicuous due to the contrast with the rear wall portion 111d can be appropriately adopted.

≪Example in which a perforation 138 is provided at the root of the insertion protrusion 25 ≫
When the window 135 as described above is employed, it is preferable to form a perforation 138 at the root of the insertion protrusion 25. As shown in FIG. 12, the perforation 138 is configured to connect the first engagement cuts 26 a and 26 a on both sides of the insertion protrusion 25. The meaning of providing such a perforation 138 is as follows.

  When a malicious third party tries to forcefully open the box, the perforation 138 portion of the insertion protrusion 25 is weak, so the insertion protrusion 25 breaks and falls downward in the box. To do. That is, it can be seen that the insertion protrusion 25 does not exist through the window 135. As a result, it is understood that the tampering has been performed (or has been attempted).

As described above, when the window 135 and the perforation 138 are adopted, if the insertion protrusion 25 is present inside the window 135 and the case where the insertion protrusion 25 is not present, the visual difference is greatly different. Easily visually check for any abnormalities, such as “the box was not sealed properly”, “unauthorized opening”, or “unauthorized opening” it can.
The specific shape of the perforation 138 is not limited to the arch shape as shown in the figure, and an appropriate shape can be adopted as appropriate.

<< Example of forming the crease 140 on the insertion flap 22 >>
Next, a case where a crease 140 is provided for more effectively preventing unauthorized opening by a malicious third party will be described. As shown in FIG. 12, the crease 140 extends from the innermost end of the first engagement cuts 26 a and 26 a on both sides of the insertion protrusion 25 toward the opening closing portion 21. However, the specific shape, length, angle, and the like are not limited to those shown in the drawings, and appropriate forms can be appropriately adopted.
As shown in FIG. 13, when a malicious third party performs an unauthorized opening, a finger is inserted in the direction indicated by the arrow in FIG. The insertion protrusion 25 is to be pulled out while pushing the area between 140) inward of the box. That is, by pushing the upper part of the insertion protrusion 25 inward of the box, the first engagement cut 26a and the second engagement cut 31a described with reference to FIG. 6 are disengaged. It is.
However, if the crease 140 is formed, even if the upper portion of the insertion protrusion 25 is pushed inward of the box, only the wall surface constituting the insertion flap 22 bends, and the pushing operation is linked. Thus, it is difficult for the first engagement cut 26a and the second engagement cut 31a to be disengaged. On the contrary, when the crease 140 does not exist, the relationship between the first engagement cut 26a and the second engagement cut 31a is linked to the pushing operation by the amount of rigidity of the wall surface constituting the insertion flap 22. It becomes easy to come off. By forming the crease 140, such inconvenience can be prevented.

In each of the embodiments described above, an unauthorized opening prevention mechanism that utilizes the engagement between the insertion protrusion and the insertion port is employed only for the upper lid, but the bottom wall of the box It is possible to provide a similar mechanism (or only for the bottom wall).
In addition, although an example in which the insertion protrusion and the insertion port have only one engagement portion has been described, a plurality of sets of insertion protrusions and insertion ports are formed in parallel to be engaged at a plurality of locations. It is good also as a structure which matches.

≪Configuration for authorized buyers to open≫
In addition, you may provide the structure which the consumer who purchased goods normally can open the said box easily. FIG. 14 shows an example of such a configuration.
FIG. 14A is a rear perspective view corresponding to FIG. 10, and a breaking line 150 for opening is formed on the rear wall 111d. In the case of breaking, the finger can be inserted into the portion 150a to break the breaking region 151 surrounded by the breaking line 150.
FIG. 14B is a rear perspective view showing a state after breaking the fracture region 151. The area surrounded by the breaking line 150 is torn off, and the folded piece 130 is visible at that portion. And the insertion protrusion 25 inserted in the insertion port 131 formed in the folding piece 130 is exposed. The authorized purchaser can open the box body by tearing off the exposed insertion protrusion 25 or pushing up the insertion protrusion 25 to separate it from the insertion port 131.
In addition, as a structure for a regular purchaser to open, not only what is shown in FIG. 14, but a proper thing, such as a zipper structure generally employ | adopted in box confectionery etc., is employable.
