[Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3236648 DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0005] The device in Patent Document 1 has a structure that makes it difficult to open, in which an insert piece is inserted into a slit to seal or lock it, but it has a complex shape that requires, for example, a tear-off guide hole, and is therefore difficult to manufacture.

[0006] Therefore, in order to solve the above problems, this invention aims to provide a packaging box with an anti-tampering function that has an extremely simple structure, but which cannot be easily opened when the lid is placed over the main body and the insertion piece is inserted into the slit, and which can be opened by peeling off part of the side panel of the main body from the slit to release the lock. [Means for solving the problem]

[0007] The invention of claim 1 relates to a packaging box with an anti-tampering function, which is made up of a box body and a lid, with side panels raised from each edge of a quadrilateral bottom panel and connected to each other, the upper edge of the side panel located on the back of the box body being integrally connected to one side of the rear end of the rectangular top panel of the lid via a fold, with the lid side panel hanging down from the front end of the top panel of the lid via a fold, and the lid side panel being placed over the front side panel of the box body to cover the lid panel, wherein upper edge flaps are provided at the upper edges of the left and right side panels of the box body via the folds, two notches are made at a distance in the lid side panel with an insert piece provided therebetween, the insert piece has a shape with a narrow base and a bulge at its tip, and a slit is provided in the front side panel of the box body with a width equal to or shorter than the width of the bulge of the insert piece, into which the insert piece is inserted,

[0008] The invention of claim 2 relates to a packaging box with an anti-tampering function, which comprises a box body and a lid body, with side panels raised from each side of a quadrilateral bottom panel and connected to each other, the upper edge of the side panel located on the back of the box body being integrally connected to one side of the rectangular top panel of the lid body via a fold, with lid side panels hanging down from the other three sides of the top panel of the lid body and these lid side panels being connected to each other, and which is fitted over the side panels of the box body, wherein two notches are made at a distance from each other in the lid side panel on the front of the lid body with an insert piece provided therebetween, the insert piece having a shape with a narrow base and a bulge at its tip, and a slit is provided in the front side panel of the box body with a width equal to or shorter than the width of the bulge of the insert piece, into which the insert piece is inserted.

[0009] In addition, the invention of claim 3 is directed to a packaging box with anti-tampering functions as described in claim 1 or 2, in which the slit has a curved shape with a central portion raised above the front side panel of the box body.

[0010] In addition, the invention of claim 4 relates to a packaging box with anti-tampering functions as described in claim 1 or 2, in which the insertion piece is provided in the center of the side panel, the base is tapered inward, and both side portions from the base to the tip are bulging portions that protrude laterally, and the tip is tapered.

[0011] In addition, the invention of claim 5 is directed to a packaging box with an anti-tampering function as described in claim 1 or 2, in which perforated cut holes are provided from both ends of the curved slit in the front side panel of the box main body to the lower end of the side panel. Effect of the Invention

[0012] According to the invention of claim 1, when the lid body is placed over the box main body and the insert piece is inserted into the slit by slightly bending both side ends of the insert piece or by inserting the insert piece diagonally into the slit from one side of the insert piece, the width of the slit is the same as or shorter than the width of the bulging part of the insert piece, so that the insert piece is engaged with the slit and cannot be removed accidentally, and the lid body is locked.

[0013] In this state, almost the entirety of the insertion piece is inserted into the slit, so only a small portion of the base of the insertion piece is exposed, and both sides of the lid are blocked by upper edge flaps provided from the upper edges of the left and right side panels of the box body, so the box body is completely covered and sealed by the lid. In addition, there are almost no protrusions or recesses on the outside of the lid and box body, so there are no clues to opening the box. Therefore, a third party cannot tamper with the box or mix foreign objects into the box body. In addition, the product placed in the packaging box cannot be removed or replaced, so the box has a function to prevent tampering.

[0014] According to the invention of claim 2, similar to the invention of claim 1, the lid is locked by inserting the insert piece of the lid into the slit on the front side panel of the box body. In this state, the three side panels of the lid cover the box body, sealing the box body. There are almost no protrusions or recesses on the outside of the lid and box body, so there is no clue to opening the box. Therefore, a third party cannot tamper with the box or mix foreign objects into the box body. In addition, the product in the packaging box cannot be removed or replaced, so the box has a function to prevent tampering.

[0015] In addition, in both of the devices of claims 1 and 2, when removing the stored product from the packaging box, insert a finger into the slit and pull the front side panel of the box body outward and downward, the side panel below the slit of the side panel of the box body is cut and peeled off, exposing the insertion piece, and the lid body can be removed from the box body. If this is not done, the lid body cannot be opened, and if the lid body of the packaging box is opened illegally, the tampering will be obvious at a glance.

[0016] In addition, in the invention of claim 3, the width of the slit is the same as or shorter than the width of the bulging part of the insertion piece, making it difficult to insert the insertion piece into the slit, but since the slit is curved, it becomes easier to insert the insertion piece when the insertion piece is bent or offset from the slit. Also, it is easier to insert a finger when opening the lid body.

[0017] According to the invention of claim 4, the tip of the insertion piece is tapered and the base is also narrowed, and there are bulges protruding on both sides between them, so when inserting the insertion piece into the slit, the tip of the insertion piece is shifted diagonally relative to the slit, making it easy to insert the insertion piece into the slit. On the other hand, if the bulges protruding on both sides of the insertion piece are completely inserted into the slit, the width of the slit is the same as or shorter than the width of the bulges on both sides of the insertion piece, so the insertion piece is difficult to remove from the slit even if the cover part is pulled by hand.

[0018] According to the invention of claim 5, perforated cutouts are provided from both ends of the slit to the bottom end of the side panel having the slit, so that when a finger is hooked on the slit and the side panel is pulled outward and downward, the perforated cutouts act as a guide and the side panel is torn off at that point, the insertion piece is exposed to the outside, and the lock on the lid is released. This makes it easier to open the container. [Brief description of the drawings]

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] (Embodiment Example 1) A packaging box A with a tamper-proof function according to a first embodiment of the present invention will be described with reference to Figs. 1 to 9.

[0021] As shown in Fig. 1, this packaging box A with tamper-proof functions is composed of a box body 1 and a lid body 2, and side panels 4 are raised from each side of a quadrilateral bottom plate 3 and connected to each other to form the box body 1. The upper edge of the side panel 4 located on the back of the box body 1 is integrally connected to one side of a quadrilateral top plate 5 of the lid body 2 via a fold, and a lid side panel 6 hangs down from one side of the front end of the top plate 5 of the lid body 2 via a fold, so that the lid body 2 covers the opening of the box body 1, and the lid side panel 6 covers the side panel 4 on the front of the box body 1.

[0022] Fig. 2 is a development of the backing of the packaging box A with a tamper-proof function. As shown in Fig. 2, folding pieces 7, 7 are respectively provided protruding from both ends of the side panel 4, which is the front of the box body 1, via creases, and upper edge flaps 8, 8 are respectively provided along the upper edges of the side panels 4, 4, which are the left and right side panels, via creases. In addition, folding tongue pieces 9, 9 are respectively provided along the rear ends of the left and right side panels 4, 4 via creases. Furthermore, oblique folding creases 10, 10 are provided from the adjacent corners of the bottom panel 3 and the front side panel 4 to the outer ends of the left and right side panels 4 and the upper edge flaps 8.

[0023] Furthermore, in the center of the lid side plate 6, notches 11, 11 are provided at intervals from the lower edge of the lid side plate 6 toward the upper part (from the upper edge toward the lower part in FIG. 2), and an insertion piece 12 is provided between these notches 11, 11. The insertion piece 12 has a base 12a cut from both sides to form an inwardly tapered shape, and both sides from the base 12a to the tip 12c form bulging parts 12b that protrude laterally, and the tip 12c has a tapered shape.

[0024] A curved slit 13 is provided in the center of the side plate 4 that serves as the front side plate. The curved slit 13 has a curved shape with the center rising toward the upper part (lower part in FIG. 2) of the side plate 4 at the front of the box body 1. The left and right width (length) of the curved slit 13 is the same as or shorter than the width of the protruding pieces 12b on both sides, which is the maximum width of the insertion piece 12. Perforated cutout holes 14 are provided between both ends of the curved slit 13 and the lower edge (upper edge in FIG. 2) of the side plate 4.

[0025] To assemble the packaging box A with anti-tampering functions from this mount, as shown in Figure 3, raise each of the side panels 4 on each of the four sides of the bottom panel 3 of the box body 1, fold each fold-in piece 7 inward toward the inside of the left and right side panels 4, and attach each fold-in piece 7 to the portion of each side panel 4 above the folding crease line 10 of each side panel 4.

[0026] When storing or transporting the packaging box A with tamper-proof functions, as shown in Figure 4, the 10 left and right folding creases are folded, and the left and right side panels 4 and upper edge flap 8 are placed on top of the bottom panel 3, and then the side panel 4 which will become the front is placed on top of that, and then the lid body portion 2 (not shown) is placed on top of that, thereby folding the packaging box A with tamper-proof functions flat.

[0027] When using the packaging box A with anti-tampering functions, the lid body 2 is opened from the folded state, and the front side panel 4, the left and right side panels 4, 4, and the upper edge flaps 8, 8 in FIG. 4 are raised almost vertically from above the bottom panel 3 as shown in FIG. 5, and further, the upper edge flaps 8 of the left and right side panels 4 are folded inward as shown in FIG. 6, and the fold-in tongues 9, 9 are folded along the rear edge of the bottom panel 3.

[0028] 7, the top plate 5 of the lid body 2 is folded from the upper edge of the back side plate 4 to cover the opening of the box body 1, and the insertion piece 12 of the front end lid side plate 6 is inserted into the curved slit 13 of the front side plate 4 of the box body 1. Then, as shown in Figs. 8 and 9, the insertion piece 12 is inserted into the curved slit 13 up to its base 12a.

[0029] In this case, since the width of the curved slit 13 is the same as or shorter than the width of the bulging parts 12b on both sides, which is the maximum width of the insertion piece 12, when inserting the bulging part 12b of the insertion piece 12 into the curved slit 13, the insertion piece 12 is inserted at an angle to the curved slit 13, and the bulging parts 12b, 12b on both sides are inserted into the curved slit 13 and inserted up to the base part 12a. Also, if the packaging box A with tamper-proof function is a paper box, the insertion piece 12 and the curved slit 13 are flexible, making it easy to insert.

[0030] As a result, the packaging box A with the tamper-proof function is sealed, and even if an attempt is made to open the lid body portion 2, the bulging portions 12 on both sides of the insertion piece 12 are caught at b and cannot be removed from the curved slit 13, preventing unauthorized opening by a third party.

[0031] To open this box, insert your fingers into the curved slit 13 in the front side panel 4 of the box body 1 and pull downward, causing the front side panel 4 to cut through the perforated cut holes 14 on both ends of the curved slit 13, exposing the insertion piece 12. Then, the lid 2 can be opened from the box body 1, and the box is opened.

[0032] Once the lid body 2 is closed in this manner, the box cannot be opened unless the side panel 4 on the front of the box body 1 is cut away around the curved slit 13, so if a third party opens the box illegally, it is immediately obvious that the box has been opened.

[0033] (Embodiment Example 2) A packaging box B with a tamper-proof function according to a second embodiment of the present invention will be described with reference to Figs.

[0034] As shown in Fig. 10, this packaging box B with tamper-proof function is composed of a box body 21 and a lid body 22, and side plates 24 are raised from each side of a quadrilateral bottom plate 23 and connected to each other to form the box body 21. The upper edge of the side plate 24 located on the back surface of the box body 21 is integrally connected to one side of a quadrilateral top plate 25 of the lid body 22 via a fold, and lid side plates 26 hang down from three sides of the front end and left and right ends of the top plate 25 of the lid body 22 via folds, and these lid side plates 26 are connected to each other, so that the lid body 22 covers the opening of the box body 21, and the three lid side plates 26 cover the side plates 24 of the box body 21.

[0035] Fig. 11 is a development of the backing sheet of the packaging box B with a tamper-proof function. As shown in Fig. 11, fold-in pieces 27, 27 are respectively provided protruding through folds at both left and right ends of the side plate 24 that forms the front of the box body 21, and upper edge flaps 28, 28 are respectively provided along the upper edges of the side plates 24, 24 that form the left and right side plates via folds. Also, fold-in pieces 29, 29 are respectively provided along the folds at both left and right ends of the side plate 24 that forms the back.

[0036] In addition, diagonal folding creases 30a, 30a are provided from adjacent corners between the bottom plate 23 and the front side plate 24 to the outer end of the front side plate 24. In addition, diagonal folding creases 30b, 30b are provided from the rear corners of the left and right side plates 24 to the outer ends of the side plates 24 and the upper edge flaps 28, respectively.

[0037] Also, the three sides of the top plate 25 of the lid part 22 are provided with a lid side plate 26, which is the front side, and left and right lid side plates 26, 26, each with a fold. Also, the left and right ends of the lid side plate 26, which is the front side, are provided with fold-in pieces 35, 35, each with a fold. Then, the lid side plate 26, which is the front side, is provided with notches 31 from two spaced apart positions on the lower edge (upper edge in FIG. 11) toward the upper part (lower part in FIG. 11), and an insertion piece 32 is provided between these notches 31. These notches 31 and insertion pieces 32 have the same shape and configuration as the notch 11 and insertion piece 12 of the first embodiment. Therefore, the insertion piece 32 is composed of a base 32a, a bulging part 32b protruding on both sides, and a tip part 32c.

[0038] Furthermore, a curved slit 33 is provided in the center of the side plate 24 on the front of the box main body 21 so as to face the lower edge (upper edge in FIG. 11), and the curved slit 33 is into which the insertion piece 32 of the lid side plate 26 is inserted, and has a curved shape with the center rising toward the upper part (lower part in FIG. 11) of the side plate 24. An auxiliary slit 33a is provided in the center of the curved slit 33 so as to face the upper edge (lower edge in FIG. 11) of the side plate 24.

[0039] Similarly to the first embodiment, the width (length) of the curved slit 33 is equal to or shorter than the width of the bulging portion 32b, which is the maximum width of the insertion piece 32. Perforated cutout holes 34 are provided between both ends of the curved slit 33 and the lower end of the side plate 24 (the upper edge in FIG. 11).

[0040] To assemble the packaging box B with tamper-proof function from this mount, as shown in Fig. 12, the four side panels 24 are raised from the bottom panel 23 of the box body 21, and the left and right fold-in pieces 27, 27 and 29, 29 are attached to the inside of the left and right side panels 24, respectively, to connect the four side panels 24 to each other. Then, the upper edge flaps 28 are folded inward through the creases on the upper edges of the left and right side panels 24. In addition, the cover side panels 26 of the cover 22 are raised from the top panel 25, and the left and right fold-in pieces 35, 35 are attached to the inside of the left and right cover side panels 26, respectively.

[0041] Then, the lid 22 is placed over the opening of the box body 21 via the crease at the rear edge of the top plate 25 of the lid 22, the lid side plates 26 are placed over the outsides of the side plates 24 of the box body 21, and the front insertion piece 32 is inserted into the curved slit 33 up to its base 32a. The insertion procedure is the same as in the first embodiment.

[0042] Furthermore, in this embodiment 2, since the curved slit 33 has an auxiliary slit 33a in the center thereof, when the insertion piece 32 is inserted into the curved slit 33, the curved slit 33 is easily deformed, making it easier to insert the protruding pieces 32b on both sides of the insertion piece 32 into the curved slit 33. Also, when the packaging box B with tamper-proof functions is a paper box, the paper is more flexible and easier to insert. This results in a sealed packaging box B with tamper-proof functions, as shown in FIG. 13.

[0043] The procedure for opening the lid body portion 22 of this packaging box B with tamper-proof function is the same as that of the first embodiment.

[0044] Although not shown in the figures, if the folding crease lines 30a, 30b, and 30c are folded from the state shown in FIG. 12, it can be folded flat in the same manner as in the first embodiment, and does not take up much space during transportation or storage.

[0045] In the above-mentioned first and second embodiments, the slit into which the insert piece 12 or 32 is inserted is the curved slit 13 or 33, but the slit may be linear. In the above-mentioned first and second embodiments, the perforated cutout holes 14 or 34 are provided from both ends of the curved slit 13 or 33 to the lower edge of the side plate 4 or 24, but these perforated cutout holes 14 or 34 are not essential requirements of this device. In the above-mentioned second embodiment, the auxiliary slit 33a is provided in the center of the curved slit 33, but the above-mentioned first embodiment may also provide an auxiliary slit in the curved slit 13. However, the auxiliary slit is not essential requirements of this device. [Explanation of symbols]
