[First Embodiment]
FIG. 1 is a perspective view showing a state before opening (sealed (sealed) state) of the packaging box 10 shown as the first embodiment, and FIG. 2 is a perspective view showing a state after opening (opening state) of the packaging box 10. It is a figure. As shown in these figures, the entire packaging box 10 has a substantially rectangular parallelepiped shape.

FIG. 3 is a view of the formed piece of the packaging box 10 (hereinafter referred to as “blank 5”) shown in FIG. 1 (or FIG. 2) as viewed from the surface side of the packaging box 10, and FIG. 4 is a blank. 5 is a view of 5 as viewed from the back surface side of the packaging box 10. The blank 5 is formed by punching a blank sheet such as thick paper or paperboard with a punching machine or the like.

In FIGS. 3 and 4, among the lines drawn at the boundaries of each piece of paper, the broken line indicates a mountain fold line, the alternate long and short dash line indicates a valley fold line, the dotted line indicates a break line, and the solid line indicates a cut line. The break line is, for example, a perforation, a cut line having an intermittently formed joint portion, or the like. The break line may also function as a mountain fold line or a valley fold line.

As shown in FIG. 3, the blank 5 has four side plates (first side plate 11, front plate 12, second side plate 13, and back plate) connected so that their long sides are parallel to each other. 14), the connection piece 17 (glue flap) extended to one end of the four side plates in the connecting direction, and the first extending to one of the short sides of the back plate 14 in the direction perpendicular to the connecting direction. There are an end face plate 15 (top plate), a second end face flap 142 extending to the other side of the short side in a direction perpendicular to the connecting direction of the back plate 14, and a second end face flap 142 of the front plate 12. It has a second end face plate 16 (bottom plate) extended to the side.

The first side plate 11, the front plate 12, the second side plate 13, the back plate 14, and the connecting piece 17 are connected in this order with their long sides as boundaries, and these are bent along each boundary. By starting up, a square tubular body having a space for storing the contents of the packaging box 10 is formed. When forming the tubular body, the connecting piece 17 is coated with an adhesive (hot melt or the like) on the back surface side or the front surface side thereof, and is adhered to the front surface side or the back surface side of the first side surface plate 11.

On the first end face plate 15, the tongue piece 151 and the residual cut piece 152 extend in order in the direction opposite to the side where the back plate 14 exists. A break line 68 is formed at the boundary between the tongue piece 151 and the residual cut piece 152. A finger hook portion 153 on which the user puts a finger on the tongue piece 151 when the packaging box 10 is opened is formed between the tongue piece 151 and the residual cut piece 152. When the packaging box 10 is opened, the tongue piece 151 and the residual piece 152 are separated. When the packaging box 10 is resealed, the tongue piece 151 is inserted into the inside of the above-mentioned cylinder along the back surface of the front plate 12 so as to close one end surface of the above-mentioned cylinder by the first end face plate 15.

The front plate 12 and the back plate 14 have the same shape (substantially rectangular shape), and these form a pair of side surfaces of the above-mentioned cylinder. Further, the first side plate 11 and the second side plate 13 also have the same shape (substantially rectangular shape), and these form a pair of side surfaces in the above-mentioned tubular body. When the packaging box 10 is sealed or resealed, the second end face plate 16 and the second end face flap 142 close the other end face of the above-mentioned cylinder.

In this example, the areas of the front plate 12 and the back plate 14 are larger than the areas of the first side plate 11 and the second side plate 13, but the area ratios thereof are not necessarily the same. It is not limited to the mode shown in. Further, the relationship between the long side and the short side of each side plate (which side is the long side or the short side) is not limited to the mode shown in the figure.

As shown in FIG. 3, a mountain fold line 31 is formed at the boundary between the first side plate 11 and the front plate 12, and a mountain fold line 32 is formed at the boundary between the front plate 12 and the second side plate 13. .. Further, a mountain fold line 41 is formed at the boundary between the second side surface plate 13 and the back plate 14, and a mountain fold line 42 is formed at the boundary between the back plate 14 and the connecting piece 17. In the case of the illustrated packaging box 10, the mountain fold line 31, the mountain fold line 32, the mountain fold line 41, and the mountain fold line 42 are all parallel to each other.

In the state where the above-mentioned cylinder is formed, the flap 111 is provided via the mountain fold line 61 on the side where the first end face plate 15 of the first side plate 11 exists, and the above-mentioned cylinder of the first side plate 11 is formed. The flap 112 extends via the mountain fold line 62 on the side where the second end face plate 16 is present in the state where the second end face plate 16 is present.

In the state where the above-mentioned cylinder is formed, the flap 131 is provided via the mountain fold line 63 on the side where the first end face plate 15 of the second side plate 13 exists, and the above-mentioned cylinder of the second side plate 13 is formed. The flaps 132 extend via the mountain fold line 64 on the side where the second end face plate 16 exists in the state where the two end face plates 16 are present.

The first end face plate 15 extends to the back plate 14 via the mountain fold line 35. Further, the second end surface flap 142 extends to the back plate 14 via the mountain fold line 38. Further, the second end face plate 16 extends to the front plate 12 via the mountain fold line 66.

When the packaging box 10 is sealed, the back surface of the residual cut piece 152 is adhered to a predetermined region G on the surface of the front plate 12 via an adhesive. At this time, the first end face plate 15 closes the end face of the above-mentioned cylinder in a state of being overlapped on the flap 111 and the flap 131 (referred to as the outer peripheral side of the packaging box 10; the same applies hereinafter). Further, the second end face plate 16 is overlapped on the flap 112 and the flap 132, further overlapped on the second end face flap 142, and adhered to the second end face flap 142 to form the other end face of the above-mentioned cylinder. Block. For example, hot melt is used for bonding each of the above parts. The position and area of the area to which the adhesive is applied are not necessarily limited.

When the contents are taken out from the sealed packaging box 10 shown in FIG. 1, the user puts a finger on the finger hook portion 153 and rolls up the tongue piece 151 to break the break line 68 and cut the tongue piece 151 as a residual cut. It is separated from the separated piece 152, and the first end face plate 15 is pulled up together with the tongue piece 151. As a result, the user can easily open the packaging box 10. By separating the tongue piece 151 from the residual piece 152, the trace of opening is surely left in the packaging box 10.

A substantially half-moon-shaped notch 125 is formed in the vicinity of the center of the end side of the front plate 12 on the side where the first end face plate 15 exists. The cutout portion 125 serves to facilitate the user to insert a finger and pull up the first end face plate 15 when the packaging box 10 is opened.

At the predetermined position of the first side plate 11, the tamper-proof sheet ("tamper-proof seal", "opening prevention seal", "opening prohibition seal", "opening confirmation seal", "VOID seal", "seal seal", etc. The films 113 and 114 that function as (referred to as) are provided. The films 113 and 114 are all heat-welded films made of resin (PP, polyester, PET, ABS, etc.). The planar shape of the films 113 and 114 is not necessarily limited, but may be, for example, a strip shape (tape shape), a rectangular shape, a circular shape, a polygonal shape, or the like. Further, the colors of the films 113 and 114 are not necessarily limited, but are transparent, for example.

As shown in FIG. 3, the film 113 is provided on the side of the first side surface plate 11 where the first end face plate 15 exists. Further, the film 114 is provided on the side where the second end face plate 16 of the first side plate 11 exists. Both the films 113 and 114 are attached to the blank 5 in advance by heat crimping in the step before the above-mentioned tubular body is formed (before the packaging box 10 is started up).

As shown in the figure, the illustrated film 113 has a substantially rectangular shape. The film 113 is provided so that a region 113a, which is about half the area thereof, covers the surface of the first side surface plate 11. This region 113a is firmly attached to the surface of the first side surface plate 11 by, for example, heat-pressing with sufficient heat and pressure. On the other hand, with respect to the region 113b over the flap 111 of the film 113, only a predetermined range Sa near the end thereof is heat-welded to the surface of the flap 111 in the manufacturing process of the blank 5.

The reason why the predetermined range Sa is heat-welded to the surface of the flap 111 is to temporarily fix the region 113b to the blank 5 so that the manufacturing apparatus can easily and accurately form the notch 113c shown in the figure. be. The notch 113c induces cutting and curling when a malicious person tries to peel off the film 113 using a cutter or the like, and acts so that traces of falsification are likely to remain in the packaging box 10. The mode of the cut 113c is not necessarily limited as long as it is a mode that easily induces the above-mentioned separation and curling.

In the state where the blank 5 is completed, the portion of the predetermined range Sa of the region 113b is cut off, and the region 113b extends from the region 113a in a free state (fluttering state). As shown in FIG. 1, the region 113b extending in the free state is heat-welded to the surface of the first end face plate 15 when the packaging box 10 is sealed, and together with the region 113a constitutes a falsification prevention sheet. A cut 113d (break line) is formed at the boundary between the region 113a and the region 113b (a portion along the mountain fold line 61), and the cut 113d is separated when the first end face plate 15 is pulled up. That is, the separation of the cut 113d is a trace indicating that the packaging box 10 has been opened.

As shown in FIG. 3, the film 114 has a substantially rectangular shape. The film 114 is provided so that a region 114a, which is about half of the area thereof, covers the surface of the first side surface plate 11. This region 114a is firmly attached to the surface of the first side surface plate 11 by heat-pressing with sufficient pressure. On the other hand, regarding the region 114b over the flap 112 of the film 114, in the manufacturing process of the blank 5, only a predetermined range Sb near the end thereof is heat-welded to the surface of the flap 112.

The reason why the predetermined range Sb is heat-welded to the surface of the flap 112 is that the region 114b is temporarily fixed to the blank 5 so that the notch 114c shown in the figure can be easily and accurately formed by the manufacturing apparatus. be. The notch 114c induces cutting and curling when a malicious person tries to peel off the film 114 using a cutter or the like, and acts so that traces of falsification are likely to remain in the packaging box 10. The mode of the cut 114c is not necessarily limited as long as it is a mode that easily induces the above-mentioned separation and curling.

In the state where the blank 5 is completed, the portion of the predetermined range Sb of the region 114b is cut off, and the region 114b extends from the region 113b in a free state (fluttering state). As shown in FIG. 5, the region 114b extending in the free state is heat-welded to the surface of the second end face plate 16 when the packaging box 10 is sealed, and together with the region 114a, constitutes a falsification prevention sheet. A cut 114d (break line) is formed at the boundary between the region 114a and the region 114b (a portion along the mountain fold line 62), and the cut 114d is cut off when the second end face plate 16 is pulled up. That is, the cut 114d is a trace indicating that the packaging box 10 has been opened.

As described above, since the films 113 and 114 are already attached to the blank 5 in the completed state, the contents to be sold or the like are packed or sealed in the packaging box 10 of the provider or the like. The time and effort required to attach the falsification prevention sheet on the side can be greatly reduced.

[Flow from manufacturing to disposal]
Then, along with the flow chart (flow chart) shown in FIG. 6, the flow from the manufacture of the blank 5 to the disposal of the packaging box 10 (manufacturing of the blank 5 → startup of the blank 5, loading of the contents → sealing (sealing) → opening). → Resealing → Disposal) will be explained.

Of the steps or procedures shown in the figure, S611 to S615 are performed on the side that manufactures the blank 5 (hereinafter, referred to as "manufacturer"). Further, from S616 to S619, the contents of the product or the like are loaded into the packaging box 10, the contents are sealed, and the contents are provided to the user (hereinafter referred to as "provider"). Further, S620 to S622 are performed by the user (hereinafter referred to as "user") of the packaging box 10 (contents).

As shown in the figure, first, the manufacturer punches the blank 5 from the blank sheet using a punching machine (S611).

Subsequently, the films 113 and 114 are attached to the blank 5 (S612). Specifically, the region 113a of the film 113 is heat-bonded to the surface of the first side plate 11, and the region 114a of the film 114 is heat-bonded to the surface of the first side plate 11. Further, the region Sa of the region 113b is heat-bonded to the surface of the flap 111, and the region Sb of the region 114b is heat-bonded to the surface of the flap 112. Here, since the films 113 and 114 are attached to the blank 5 in a flat state, relatively high pressure can be applied by these heat crimping, and the films 113 and 114 can be reliably attached to the blank 5. It can be attached to the surface. Thereby, for example, the films 113 and 114 can be attached to the blank 5 with sufficient strength to withstand the transportation of the blank 5.

Subsequently, a notch 113c is formed in the film 113, and a notch 114c is formed in the film 114 (S613). The notch 113c and the notch 114c are formed to such an extent that a part of the film 113 or the film 114 is not cut off.

Subsequently, the region Sa is separated from the region 113b, and the region Sb is separated from the region 114b (S614). As a result, the region 113b and the region 114b are in a free state (fluttering state).

Subsequently, the blank 5 is finished (S615). Specifically, the ruled line is habituated by the sack machine, and the connection piece 17 and the first side plate 11 are bonded to each other. In the process of adding the habit, for example, the four side plates of the blank 5 (first side plate 11, front plate 12, second side plate 13, and back plate 14) and the connecting piece 17 are bent (mountain fold lines 31, 32). , 41, 42) is performed. Further, in the above-mentioned bonding step, an adhesive is applied to the front surface (or back surface) of the connection piece 17, and the front surface (or back surface) of the connection piece 17 is adhered to the back surface (or front surface) of the first side plate 11.

This completes the blank 5 shown in FIGS. 3 and 4. The blank 5 is then handed over from the manufacturer to the content provider.

When loading the contents, first, the blank 5 is started up by using a carting machine (box making machine) or the like, and the above-mentioned tubular body is formed (S616).

Subsequently, as shown in FIG. 7, the contents are loaded into the cylinder by the boxing machine, and both end faces of the cylinder are closed (S617). By going through this step, the packaging box 10 is in the state shown in FIG. As shown in the figure, in this state, the region 113b of the film 113 and the region 114b of the film 114 are free (fluttering) on both sides (+ z direction, −z direction) of the packaging box 10 in the longitudinal direction. It is extended in the state of). In the content loading / sealing step, the packaging box 10 is placed on a belt conveyor in this state, for example, and is conveyed to the next step. In this step, when the both end faces are closed, the region 113b of the film 113 is folded together with the flap 111, and the region 114b of the film 114 is not folded together with the flap 112, for example, in the regions 113b and 114b, respectively. A blower is used to blow air from the back surface side of the box to prevent the areas 113b and 114b from being folded by the boxing machine. Further, for example, the lengths of the regions 113b and 114b extending in the + z direction (the length extending in the + z direction for the regions 113b and the length extending in the −z direction for the regions 114b) are the flaps 111, respectively. Shorter than 112, i.e. shorter than the length of the flap 111 extending in the + z direction for the region 113b, and shorter than the length of the flap 112 extending in the −z direction for the region 114b. You may do so. By doing so, the boxing machine is set so that the hooks (claw) of the boxing machine that are hooked on the flaps 111 and 112 when folded are caught only on the flaps 111 and 112 and are not caught on the areas 113b and 114b. It is possible to more reliably prevent the regions 113b and 114b from being folded together with the flaps 111 and 112 in the process.

Subsequently, as shown in FIG. 9, the regions 113b are on the surface of the first end face plate 15 and the regions 114b are on the surface of the second end face plate 16 so that the films 113 and 114 function as tamper-proof seals, respectively. It is heat crimped. In the example of the figure, the regions 113b and 114b are heat-bonded by applying heat welding heaters I from both end faces of the cylinder (S618). If too much pressure is applied, the packaging box 10 may be crushed, so it is not possible to apply too high pressure, but the regions 113b and 114b are attached to the packaging box 10 with practically sufficient adhesive force by heat welding. can do.

With the above, the sealing of the packaging box 10 is completed, and then the packaging box 10 reaches the user's hand via the distribution channel or the like (S619).

When opening the packaging box 10, the user first puts a finger on the finger hook portion 153 of the packaging box 10, cuts the tongue piece 151 from the residual cutting piece 152, and rolls up the first end face plate 15. As a result, the end face of the cylinder is opened, and the packaging box 10 is in the opened state shown in FIG. 2 (S620). The user takes out the contents from the packaging box 10 in this state.

When the user continues to use the packaging box 10 as it is, the user inserts the tongue piece 151 into the above-mentioned cylinder along the back surface of the front plate 12, closes the end face of the cylinder with the first end face plate 15, and the packaging box. 10 is resealed (S621).

After that, when the packaging box 10 ends its role due to the consumption of the contents or the like, the user disassembles the packaging box 10 and disposes of it (S622).

[Falsification prevention function]
As shown in FIG. 10, a malicious person applies heat to the adhesive (hot melt) applied to the back surface of the residual cut piece 152 by using, for example, a heating device H such as a dryer to melt the adhesive, and then melts the packaging box. The residual piece 152 is peeled off from the front plate 12 so as not to leave a trace on 10, and an attempt is made to access the contents. However, even if a malicious person can peel off the residual fragment 152 without leaving a trace, the contents cannot be accessed unless the first end face plate 15 is peeled off due to the structure of the packaging box 10. If a malicious person tries to forcibly open the first end face plate 15, the cut 113d of the film 113 is cut off, and a trace is always left in the packaging box 10.

Further, as shown in FIG. 11, a malicious person applies heat to the adhesive (hot melt) applied to the back surface of the second end face plate 16 by using, for example, a heating device H such as a dryer to melt the adhesive. An attempt is made to access the contents by opening the second end face plate 16 so that no trace is left on the packaging box 10. However, if a malicious person tries to open the second end face plate 16, the cut 114d of the film 114 is cut off, and a trace is always left in the packaging box 10.

By the way, a pigment having a color that is easily visible may be applied to the area on the surface of the packaging box 10 to which the films 113 and 114 are attached. As a result, when a malicious person tries to peel off the films 113 and 114, the pigment sticks to the films 113 and 114 and peels off, so that the trace of the falsification operation can be surely left in the packaging box 10. In this case, it is advisable not to apply a coating to the surface of the pigment (or to prevent the coating material from being mixed with the pigment). By doing so, the pigment is more likely to stick to the back surfaces of the films 113 and 114, and the trace of the tampering operation can be more reliably left in the packaging box 10.

As described above, in the packaging box 10 of the present embodiment, the films 113 and 114 that function as the falsification prevention sheet are previously attached to the blank 5, so that the falsification prevention sheet can be attached when the packaging box 10 is sealed. The required process can be simplified.

Further, since the films 113 and 114 can be attached to the blank 5 when the blank 5 is in a flat state before the blank 5 is started up (formation of the tubular body described above), the films 113 and 114 can be efficiently attached. It can be reliably attached to the blank 5.

Further, when a malicious person tries to access the contents of the packaging box 10 by melting the adhesive, the trace can be surely left in the packaging box 10.

Further, the cuts 113c and 114c are formed in the films 133 and 114, and when a malicious person tries to carefully peel off the films 113 and 114 using a cutter or the like, the cuts 113c and 114c act to form the films 133 and 114. Since the 114 is easily cut off and curled up, a trace of the tampering operation can be surely left in the packaging box 10.

[Second Embodiment]
FIG. 12 is a perspective view showing a state before opening (sealing (sealing) state) of the packaging box 10 shown as the second embodiment, and FIG. 13 is a state after opening (opening) of the packaging box 10 of the second embodiment. It is a perspective view which shows the state). 14 is a view of the blank 5 of the packaging box 10 shown in FIG. 12 (or FIG. 13) as viewed from the front surface side of the packaging box 10, and FIG. 15 is a view showing the blank 5 on the back surface side of the packaging box 10. It is a view from.

The packaging box 10 of the second embodiment has the same basic configuration as the packaging box 10 of the first embodiment, but in the packaging box 10 of the second embodiment, the film 113 of the first embodiment is packed in the packaging box 10. It is different from the packaging box 10 of the first embodiment in that it is not attached to the packaging box 10 and that a new film 115 is attached to the packaging box 10 so as to straddle the residual cut piece 152 and the front plate 12. ..

As shown in FIG. 14 or FIG. 15, the illustrated film 115 exhibits a substantially rectangular shape. The film 115 is provided so that a region 115a, which is about half of the area thereof, covers the surface of the residual fragment 152. This region 115a is firmly attached to the surface of the residual fragment 152 by heat welding under sufficient pressure. On the other hand, the region 115b over the front plate 12 of the film 115 extends from the residual cut piece 152 and is in a free state (fluttering state). As shown in FIG. 12, the region 115b extending in this free state is heat-welded to the surface of the front plate 12 when the packaging box 10 is sealed, and functions as a falsification prevention sheet together with the region 115a.

A notch 115c is formed throughout the film 115. The notch 115c is provided to induce peeling when a malicious person tries to peel off the film 115 using a cutter or the like, so that traces of falsification are likely to remain. The aspect of the notch 115c is not necessarily limited. A cut 115d (break line) is formed at the boundary between the region 115a and the region 115b (on the edge of the residual cut piece 152), and the cut 115d is cut off when the first end face plate 15 is pulled up. ..

As described above, as in the case of the first embodiment, the film 115 is already attached to the blank 5 in the completed state, so that when the provider of the contents seals the packaging box 10. It is possible to reduce the load required for attaching the falsification prevention sheet.

In FIG. 16, a malicious person applies heat to the adhesive (hot melt) applied to the back surface of the residual fragment 152 by using a heating device H such as a dryer to melt the adhesive, and no trace is left in the packaging box 10. As shown above, the residual piece 152 is about to be peeled off from the front plate 12. However, when a malicious person tries to peel off the residual cut piece 152 from the front plate 12, the film 115 is cut off at the cut 115d, and a trace is always left in the packaging box 10.

Similar to the packaging box 10 of the first embodiment, the pigment is applied to the area of the packaging box 10 to which the film 115 is attached so that the pigment is peeled off together with the film 115 when a malicious person tries to peel off the film 115. You may do it. By doing so, the packaging box 10 can surely leave a trace of the operation by a malicious person on the packaging box 10. Further, in that case, the surface of the pigment may not be coated (or the coating material may not be mixed in the pigment). By doing so, the pigment easily adheres to the film 115, and it is possible to more reliably leave a trace of the operation by a malicious person on the packaging box 10.
