As described above, Patent Document 1 and Patent Document 2 disclose a packaging box having a plug-in type lid for convenience of resealing.

However, in Patent Document 1, since the insertion portion 9a provided on the tongue piece 9 is cut out by cutting the extraction break line 10, the user does not fail to cut the insertion portion 9a when extracting the insertion portion 9a. It needs to be operated carefully. Further, secure a large area as the glue margin portion 9b and firmly attach the glue margin portion 9b to the tongue piece 9 so that the insertion portion 9a is surely broken at the portion of the extraction break line 10 when the insertion portion 9a is pulled out. It is necessary and it is difficult to make the packaging box thinner. Further, since the rush portion 7 is in a free state at the time of resealing, it becomes an obstacle when opening and closing the lid portion, and the aesthetic appearance is also spoiled.

In Patent Document 2, the inner upper lid piece 56 is thinned by being peeled off in the middle of the thickness of the paper surface by the full cut line 65 and the front half cut line 66 in the state of being the insertion piece 57, and thus becomes a hinge portion. It is difficult to secure the strength of the insertion piece 57 including the above. Further, since the user puts his / her finger on the recess 60 or the end 56a to peel off the inner upper lid piece 56 from the outer upper lid piece 40, it is necessary to secure a sufficient area in the recess 60 or the end 56a so that the user can easily operate the recess 60 or the end 56a. Therefore, it is difficult to make the packaging box thinner.

Further, as described in Patent Document 3, regarding a packaging box (packaging box) containing a drug such as a drug, for example, at a pharmacy or the like, the packaging box is placed on a dispensing shelf in the state of a PTP (Press Through Package) sheet. When storing, cut out a specific part of the packaging box as a tag and attach it to the PTP sheet with a rubber ring or the like, or attach it to the specified storage position on the dispensing shelf to easily provide information on the contents taken out of the packaging box. For convenience of such work, there is a need to provide an easily removable tag on the packaging box with information about the contents. However, neither Patent Document 1 nor Patent Document 2 considers providing such a tag.

The blank 5 is formed by punching a blank sheet such as thick paper or paperboard, for example.

In FIGS. 3 and 4, the broken line indicates the mountain fold line, the alternate long and short dash line indicates the valley fold line, the dotted line indicates the break line, and the solid line indicates the cut line. The break line is, for example, a perforation, a cut line having a joint portion formed intermittently, a cut line cut leaving a part of the thickness of the blank 5 (half cut line), and the like. Break lines and cut lines may also function as mountain fold lines or valley fold lines. When the break line or the cut line functions as a mountain fold line or a valley fold line, the line type corresponding to any of the functions that are also used is selected and drawn in the figure.

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) extending at one end of the four side plates in the connecting direction, and the back plate 14 extending to one of the short sides in the direction perpendicular to the connecting direction. It has one end face plate 15 (top plate) and a second end face plate 16 (bottom plate) extending to the other side of a short side in a direction perpendicular to the connecting direction of the back plate 14.

When the packaging box 10 is used as a storage container for medicines, for example, information such as the name of the medicine is displayed on the surface of the front plate 12, and information such as the name of the medicine is displayed on the surfaces of the first side plate 11 and the second side plate 13. For example, information such as the name, type, characteristics, ingredients, efficacy, usage, dosage, expiration date (expiration date), code (RSS code, RSS composite code, JAN code, etc.) of the drug is displayed on the surface of the back plate 14. For example, information on the name and contents of the drug (number of tablets, number of drug packages, manufacturer, contact information, etc.) is displayed on the surfaces of the first end face plate 15 and the second end face plate 16, for example, the name of the drug. The information is printed or printed, respectively. For example, assuming that the product will be sold at a drug store or the like, information related to advertising such as the name of a drug may be displayed on the surfaces of the first end face plate 15 and the second end face plate 16. is there.

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 are packaged by bending and assembling them. A square tubular body is formed to form a space for storing the contents of the box 10. When forming the tubular body, the connecting piece 17 is coated with an adhesive (hot melt or the like) on the front surface side thereof and adhered to the back surface side of the first side plate 11.

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 have the same shape (substantially rectangular shape), and these form a pair of side surfaces of the above-mentioned cylinder.

The first end face plate 15 and the second end face plate 16 each function to close the two facing end faces of the above-mentioned cylinder of the packaging box 10 composed of the four side plates. In this example, the area of the front plate 12 or the back plate 14 is larger than the area of the first side plate 11 or the second side plate 13, but the area ratios thereof are not necessarily the modes shown in the figure. Not limited. Further, the relationship between the long side and the short side of each side plate (which side is to be the long side or the short side) is not limited to the mode shown in the figure.

As shown in the figure, 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. .. A break line 41 is formed at the boundary between the second side surface plate 13 and the back plate 14, and a break line 42 is formed at the boundary between the back plate 14 and the connecting piece 17. The mountain fold line 31, the mountain fold line 32, the break line 41, and the break line 42 are all parallel to each other. The break line 41 and the break line 42 also function as mountain fold lines when the above-mentioned tubular body is raised.

The strength of the break line 41 is set higher than the strength of the break line 42. This is a bending step at the time of manufacturing the packaging box 10 performed by using a carting machine (box making machine) (when the blank 5 is raised to the above-mentioned tubular state, the folding curve of the blank 5 (mountain folding line (mountain folding line (mountain folding line)). The stress acting on the connecting portion of the break line 41 and the break line 42 is taken into consideration in the step (including the break line that functions as a fold curve) and the valley fold line). That is, in the above step, the connecting piece 17 is bent up to 90 ° with respect to the back plate 14, but the back plate 14 is bent up to 180 ° with respect to the second side surface plate 13, and the breaking line 41 is formed in the above step. This is because the bending angle is larger than that of the breaking line 42, and the breaking line 41 is required to have higher strength than the breaking line 42. When both the break line 41 and the break line 42 are perforations, the above strength changes, for example, the ratio of the total length of the joint portion to the length of the other portion (cut portion). Can be adjusted by. The bending angles (90 °, 180 °) in the above steps are examples, and the bending angles are set to appropriate values from the viewpoint of improving the production efficiency of the packaging box 10.

As shown in the figure, on the side of the first side surface plate 11 where the first end face plate 15 exists in the state where the above-mentioned tubular body is formed, a flap 111 is provided via the mountain fold line 61, and the first side is also provided. On the side of the face plate 11 where the second end face plate 16 exists in the state where the above-mentioned tubular body is formed, flaps 112 are extended via the mountain fold line 62, respectively. Further, on the side of the second side surface plate 13 where the first end face plate 15 exists in the state where the above-mentioned tubular body is formed, a flap 131 is provided via the mountain fold line 63, and the above-mentioned second side surface plate 13 is described above. Flap 132s are extended via the mountain fold line 64 on the side where the second end face plate 16 exists in the state where the tubular body is formed.

A flap 121 is formed on the side of the front plate 12 on the side where the first end face plate 15 exists in the state where the above-mentioned tubular body is formed, via the folding curve 65 and the breaking line 39 continuous with the folding curve 65. .. Further, a flap 113 is formed on the side of the front plate 12 on the side where the second end face plate 16 exists in the state where the above-mentioned tubular body is formed, via the folding curve 66.

A break line 35, which also functions as a mountain fold line, is formed at the boundary between the back plate 14 and the first end face plate 15. A break line 38 that also functions as a mountain fold line is formed at the boundary between the back plate 14 and the second end face plate 16.

An insertion portion 151 is extended via a cut line 36 on the side of the first end face plate 15 facing the side where the back plate 14 is connected. The cut line 36 functions as a mountain fold line when the packaging box 10 is in the resealed state.

The first end face plate 15 is formed with a trapezoidal region (hereinafter, referred to as a trapezoidal portion 152) having a lower base 153a at a portion having a predetermined length near the center of the cut line 36. The two hypotenuses 154a and 154b of the trapezoidal portion 152 are both cut lines, and the upper base 153b of the trapezoidal portion 152 is a break line.

The length of the cut line 36 is shorter than the break line 35 forming the boundary between the back plate 14 and the first end face plate 15, whereby the boundary between the insertion portion 151 and the first end face plate 15 (cut line). A substantially triangular constriction is formed at both ends of 36).

When the packaging box 10 is in the sealed state, the insertion portion 151 uses the cut line 36 as a mountain fold line so that the back surface of the insertion portion 151 faces the back surface of the first end face plate 15. Folds in. Then, in this state, the back surface of the insertion portion 151 is an adhesive (hot melt or the like) applied to the area of the trapezoidal portion 152 on the back surface of the first end face plate 15 (for example, the shaded area indicated by reference numeral 156 in FIG. 4). ) Is adhered to the back surface of the first end face plate 15. As a result, when the packaging box 10 is in a sealed (sealed) state or the like, the insertion portion 151 can be reliably held in the folded state.

On the other hand, when the packaging box 10 is in the resealed state, the insertion portion 151 is bent with the cut line 36 as a mountain fold line, and is inserted into the edge of the opening of the tubular body described above along the back surface of the front plate 12.

A break line 39 (sewing machine blade, lead ruler, etc.) (however, a folding curve 65 is formed at a predetermined length portion at the center of the boundary) is formed at the boundary between the front plate 12 and the flap 121. Further, in the vicinity of the boundary of the flap 121 (for example, a position separated from the boundary by about 1 mm), a break line 65a extending in parallel with the folding curve 65 is formed. The break line 65a facilitates disassembly of the packaging box 10 when the packaging box 10 is discarded. The break line 65a also functions as a mountain fold line, facilitating insertion of the push-in portion 122, which will be described later, into the gap, which will be described later.

A substantially rectangular pushing portion 122 is formed in the vicinity of the center of the edge portion of the front plate 12 on the side where the flap 121 is extended. A break line 391 continuous with the break line 39 is formed on the peripheral edge of the push-in portion 122. The strength of the break line 39 and the break line 391 is set to be weaker than the strength of the break line 65a. Therefore, when the user pushes the push-in portion 122 when opening the packaging box 10, which will be described later, the break line 39 and the break line 391 are broken, but the break line 65a is not broken.

A break line 40 is formed in the vicinity of the center of the flap 121 in parallel with the boundary between the front plate 12 and the flap 121. By breaking the break line 39, the break line 391, and the break line 40, the user can cut out a cut piece having these as a part of the peripheral edge thereof from the packaging box 10. The cut piece can be used, for example, as a tag for displaying information such as information about the contents (hereinafter, referred to as a display piece 125). For example, when the packaging box 10 is used as a storage container for a drug, information such as the name, type, expiration date (expiration date), serial number, lot number, and code of the drug is displayed on the surface of the display piece 125. ..

In the sealed state, the back surface of the flap 121 region (hereinafter, referred to as glue margin piece 1211) other than the display piece 125 is formed in a predetermined region (hereinafter, referred to as glue surface 155) on the surface of the first end face plate 15. It is adhered with an adhesive (hot melt, etc.). The area of the glue margin piece 1211 can be narrowed within a range in which the strength required for the packaging box 10 can be secured. Further, the area of the insertion portion 151 can be narrowed to the extent that the end face of the cylinder described above can be closed by the first end face plate 15 when the packaging box 10 is resealed. With these, for example, a thinner packaging box 10 can be realized.

As shown in FIG. 4, two cut lines (cut line 51 and cut line 52) are formed on the back side of the back plate 14 so as to leave a part of the thickness of the blank 5. There is. Of these, the cut line 51 is formed adjacent to the break line 41 and parallel to the break line 41 (excluding the vicinity of both ends thereof). The cut line 51 is provided at a predetermined distance from the break line 41 except for the vicinity of both ends thereof in order to prevent a decrease in the strength of the packaging box 10. As shown in the figure, the cut line 51 is bent in the direction of the long side of the back plate 14 (direction of the break line 41) at an angle of about 45 ° in the vicinity of both ends thereof, and the tip thereof is eventually bent. Also reaches the corners of the back plate 14. On the other hand, the cut line 52 is formed adjacent to the break line 42 and parallel to the break line 42 (excluding the vicinity of both ends thereof). The cut line 52 is provided at a predetermined distance from the break line 42 except for the vicinity of both ends thereof in order to prevent a decrease in the strength of the packaging box 10. As shown in the figure, the cut line 52 is bent in the direction of the long side of the back plate 14 (direction of the break line 42) at an angle of about 45 ° in the vicinity of both ends thereof, and the tip thereof is eventually bent. Also reaches the corners of the back plate 14.

Subsequently, as shown in FIG. 6B, the user inserts the push-in portion 122 between the first end face plate 15 and the insertion portion 151 so that the push-in portion 122 does not interfere with the resealing or re-opening. It is inserted into the gap at the center of the cut line 36 (the gap including the portion corresponding to the lower bottom 153a of the trapezoidal portion 152), and the push-in portion 122 is fixed to the first end face plate 15. This work is unnecessary when the display piece 125 including the push-in portion 122 is separated from the glue allowance piece 1211 (the break line 40 is separated) and used as a tag. As described above, a break line 65a (mountain fold line) extending in parallel with the fold curve 65 is formed in the vicinity of the boundary of the flap 121 with the front plate 12 (near the fold curve 65), and is pushed in. By folding the portion 122 along the breaking line 65a, the surface of the pushing portion 122 is slightly displaced toward the back surface side of the insertion portion 151. Therefore, the user can easily position the end edge of the tip of the push-in portion 122 in the gap between the first end face plate 15 and the insertion portion 151, and smoothly insert the push-in portion 122 into the gap.

Subsequently, as shown in FIG. 6C, the user inserts the insertion portion 151 into the inside of the front plate 12 and closes the end face of the tubular body described above. FIG. 6D shows the state (resealed state) of the packaging box 10 after the insertion portion 151 is completely inserted into the inside of the front plate 12.

As described above, in the packaging box 10 of the present embodiment, the user can easily open the packaging box 10 by pushing the pushing portion 122 with a thumb or the like and pulling up the first end face plate 15. .. Further, when the packaging box 10 is opened, the first end face plate 15 and the insertion portion 151 folded on the back surface of the first end face plate 15 are visible to the user, so that the user can see the insertion portion for resealing. The existence can be surely recognized. Further, the user can easily insert the insertion portion 151 into the boundary line between the insertion portion 151 and the first end face plate 15 by pushing the trapezoidal portion 152 (partial area) from the surface side of the first end face plate 15 with a finger. Can be made movable as a hinge. Further, according to this structure, sufficient strength at the time of bending of the insertion portion 151 is also ensured.

Further, the user can easily insert the push-in portion 122 into the gap between the first end face plate 15 and the insertion portion 151 (the gap including the portion corresponding to the lower bottom 153a of the trapezoidal portion 152). Can be put in a state that does not interfere with resealing or reopening. This also ensures the aesthetic appearance of the packaging box 10.

Further, according to the packaging box 10 of the present embodiment, a thinner packaging box 10 can be realized by reducing the area of the glue margin piece 1211 and the area of the first end face plate 15.

Further, by separating the display piece 125 from the glue allowance piece 1211, an element of the packaging box (display piece 125) that is no longer needed after opening can be used as a tag.

<Flow from manufacturing to disposal>
Subsequently, along with the flowchart shown in FIG. 7, the flow from manufacturing to disposal (assembly->boxing-> sealing (sealing)->opening->resealing->disassembly-> disposal) of the packaging box 10 will be described.

When assembling the packaging box 10, first, a carting machine (box making machine) or the like is used to adhere the first end face plate 15 on the back surface of the insertion portion 151 to the area of the trapezoidal portion 152 on the back surface, or to attach the blank 5 to the area of the trapezoidal portion 152. The four side plates (first side plate 11, front plate 12, second side plate 13, and back plate 14) and the connecting piece 17 are bent (S711).

Subsequently, an adhesive (hot melt or the like) is applied to the surface of the connecting piece 17, and the surface of the connecting piece 17 is adhered to the back surface of the first side surface plate 11 (S712). For example, the manufacturer of the packaging box 10 delivers the packaging box 10 to the manufacturer of the contents when the transportation (transportation) efficiency is in this state.

Subsequently, the blank 5 is three-dimensionally raised using a carting machine (box making machine) or the like to form the above-mentioned tubular body (S713).

Subsequently, the contents of the packaging box 10 are packed in a cylinder using a boxing machine or the like (S714), and the packaging box 10 is sealed (sealed) (S715).

After that, the packaging box 10 reaches the user via a distribution channel or the like, and the user opens the packaging box 10 and takes out the contents (S716). If necessary, the packaging box 10 is resealed for storage of the remaining contents and the like, and is continuously used (S717). The finally used packaging box 10 is disassembled (S718) and discarded (S719) according to the procedure shown below.

<Disassembly of packaging box>
When disassembling the packaging box 10 described above, first, as shown in FIG. 8, the user picks the first end face plate 15 with a finger, rolls up the back plate 14, and peels the back plate 14 from the packaging box 10. As a result, the back plate 14 is separated from the first side plate 11, the second side plate 13, and the connecting piece 17. As described above, the two cut lines (cut line 51 and cut line 52) are both cut leaving a part of the thickness of the blank 5, and the above two cut lines are cut. When the user rolls up the back plate 14, it acts to induce delamination on the back plate 14. Specifically, by rolling up the back plate 14, the trapezoidal region surrounded by the breaking line 41 and the cutting line 51 and the trapezoidal region surrounded by the breaking line 42 and the cutting line 52, respectively, are formed. Delamination occurs. As a result, the break line 41 and the break line 42 are separated leaving a part of the thickness of the blank 5, whereby the user can remove the back plate 14 from the first side plate 11, the second side plate 13, and the connecting piece 17. The force required for separation is relaxed, and the user can easily and neatly disassemble the packaging box 10 without damaging his or her hands.

As described above, the cut line 51 is bent in the direction of the long side of the back plate 14 (direction of the break line 41) at an angle of about 45 ° in the vicinity of both ends thereof, and the tips thereof are all of the back plate 14. It has reached the corner. Further, the cut line 52 is bent in the direction of the long side of the back plate 14 (direction of the break line 42) at an angle of about 45 ° in the vicinity of both ends thereof, and the tips thereof are all at the corners of the back plate 14. Has reached. By forming both ends of the cut line 51 and the cut line 52 in such a form, the end face plate (first end face plate 15 or the second end face plate 16) and the back plate 14 required for the packaging box 10 are formed. It is possible to secure the connection strength between the two. Further, by forming both ends of the cut line 51 and the cut line 52 in such a form, when the user rolls up the back plate 14 when disassembling the packaging box 10, the delamination described above on the back plate 14 is smoothed. Can be induced in.

FIG. 9 shows a state in which the packaging box 10 after disassembly is folded. In this way, the disassembled packaging box 10 can be folded into a substantially flat state. As described above, the back plate 14 is separated from the first side plate 11, the second side plate 13, and the connecting piece 17 at the break line 41 and the break line 42, so that the packaging after disassembly is performed, for example. The bag-shaped structure that causes bulkiness does not remain on the piece of paper in the box 10.

As described in detail above, according to the present invention, it is possible to realize a packaging box 10 that has a simple structure but satisfies the required functions and strengths. The above description is for facilitating the understanding of the present invention, and does not limit the present invention. The present invention can be modified and improved without departing from the spirit thereof, and the present invention includes equivalents thereof.

For example, in the above-described embodiment, when the packaging box 10 is in the sealed state, the back surface of the insertion portion 151 is coated on the area corresponding to the trapezoidal portion 152 on the back surface of the first end face plate 15. Although it is adhered to the back surface of the first end face plate 15 with an agent, at least a part of the back surface of the insertion portion 151 is pseudo-adhered to the back surface of the first end face plate 15 (for example, together with or instead of this). An adhesive may be applied to one surface and a release agent may be applied to the other surface to bond them in a removable state. By doing so, when the packaging box 10 is in the sealed (sealed) state, the insertion portion 151 can be reliably held in the folded state.

Further, for example, in the present embodiment, the break lines 41, 42 and the cut lines 51, 52 are formed on the two sides of the back plate 14, but the break lines and the cut lines are the other side plates (first side). It may be formed on at least one of the face plate 11, the front plate 12, and the second side plate 13.
