  By the way, for example, if the number of breaks (perforations, etc.) provided in the packaging box is given priority for ease of disassembly, it is difficult to ensure the robustness required at the time of manufacture, transportation, use, etc. Become. On the other hand, for example, if the number of flaps is increased in order to ensure robustness and resealability, the number of joints increases and the ease of disassembly of the packaging box after use is impaired. As described above, the packaging box has a problem of satisfying both the robustness required at the time of manufacture, transportation, use, and the like and the ease of disassembly after use.

  The present invention has been made in view of such a background, and an object thereof is to provide a packaging box that has robustness and can be easily disassembled.

  In order to achieve the above object, one aspect of the present invention is an approximate configuration including four side plates and two end plates provided on each end surface of a cylindrical body constituted by the four side plates. A rectangular parallelepiped packaging box constructed by assembling blanks, the blanks being connected to each other via folding lines provided in parallel to each other, and the connecting direction of the four side plates A connecting piece extending through a folding line parallel to the folding line at one end of the cylinder, and the cylindrical body bends the blank at the folding line and connects the connecting piece to the four side plates. Adhering to the side plate at the other end in the direction and raising the blank three-dimensionally, at least two folding lines corresponding to each of the two sides of any one of the side plates are both broken Line The face plate has two cut lines formed adjacent to each other along each of the breaking lines on the back side thereof, and each of the two cut lines is cut by leaving a part of the thickness of the blank. It is assumed that it is included.

  Thus, in the packaging box of the present invention, the folding lines constituting at least two sides of any of the side plates are both broken lines, and two score lines along the broken line are formed on the back side of the side plates. (For example, a half-cut line) is formed. When the packaging line is disassembled, the two cut lines induce delamination in the blank of the side plate when the user rolls up the side plate on which the broken line and the cut line are formed along the broken line. It works to let you. For this reason, the breaking line is cut off leaving a part of the thickness of the blank, whereby the force required for the user to cut the side plate from other side plates and connecting pieces along the breaking line is increased. Alleviated. In addition, although the robustness of the packaging box is lowered by providing the break line, the strength of the break line can be increased by the amount of ease of disassembly by the above two cut lines (even if the strength is increased, disassembly And the robustness of the packaging box can be ensured. Thus, according to the present invention, it is possible to provide a packaging box that has robustness and can be easily disassembled.

  Further, as described above, the side plate is cut off from the other side plate and the connecting piece along the breaking line, so that a bag-like structure that generates elasticity in the paper piece after disassembly does not remain. . Therefore, the packaging box of the present invention is less bulky after being disassembled, and can be efficiently stored and transported at the time of disposal.

  Further, as described above, the side plate is cut off from the other side plate and the connecting piece along the breaking line, so that the ease of disassembly is not impaired even when the number of flaps is large. Therefore, the present invention can be widely applied to various types of packaging boxes.

  Another one of the present invention is the packaging box, wherein the end face plate is connected to the side plate on which the break line and the cut line are formed.

  According to the present invention, the user picks up the end face plate and rolls up the side plate on which the break line and the cut line are formed along the break line, so that the side plate is connected to another side plate or a connection plate. Can be easily separated from the side.

  Another one of the present invention is the packaging box, wherein the score line bends in the direction of the breaking line adjacent to the score line in the vicinity of the end, and the tip of the score line is Suppose that it has reached the corner of the side plate where the cut line is provided.

  In this way, the leading end of the score line terminates at the corner of the side plate on which the score line is provided, so that the strength of the connection portion between the end plate and the side plate is not affected. Further, when the user tries to separate the side plate from the other side plate and the connecting piece along the breaking line, the interlayer is smoothly formed on the side plate provided with the cut line, starting from the corner portion. Delamination can be induced.

  Another one of the present invention is the packaging box, wherein the connection piece is provided adjacent to the side plate on which the break line and the cut line are formed.

  Another one of the present invention is the packaging box, wherein the break line is a perforation or a cut line having a joint portion.

  In addition, the subject which this application discloses, and its solution method are clarified by the column of the form for inventing, and drawing.

  According to the present invention, it is possible to provide a packaging box that has robustness and can be easily disassembled.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same or similar components may be denoted by the same reference numerals and redundant description may be omitted.

  FIG. 1 is a perspective view showing a state (sealing (sealing) state) before opening of a packaging box 10 described as an embodiment of the present invention, and FIG. 2 shows a state after opening of the packaging box 10. It is a perspective view. As shown in these drawings, the entire packaging box 10 has a substantially rectangular parallelepiped shape.

  FIG. 3 is a view of a formed piece (hereinafter also referred to as “blank 5”) of the packaging box 10 shown in FIG. 1 (or FIG. 2) as viewed from the front side of the packaging box 10, and FIG. It is the figure which looked at the blank 5 from the back surface side of the packaging box 10. FIG. The blank 5 is formed, for example, by punching a blank sheet such as cardboard or paperboard. 3 and 4, 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 (a perforation line or a cut line having a connecting portion), and the like, and a solid line (a portion that becomes the outline of the blank 5). “Excluded” indicates a cut line (for example, a half-cut line) cut by leaving a part of the thickness of the blank 5 (cut to a predetermined depth in the thickness direction). As will be described later, the break line may also function as a mountain 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) a connecting piece 17 (glue flap) extending at one end in the connecting direction of the four side plates, and a first extending at one short side of the back plate 14 in a direction perpendicular to the connecting direction. An end face plate 15 (top plate) and a second end face plate 16 (bottom plate) extending on the other short side perpendicular to the connecting direction of the back plate 14 are provided. The first side plate 11, the front plate 12, the second side plate 13, the back plate 14, and the connection piece 17 are connected in this order with the respective long sides as boundaries, and the corners in which the contents of the packaging box 10 are stored. A cylindrical tube is formed. When forming the cylindrical body, the connection piece 17 is bonded to the back side of the first side plate 11 by applying an adhesive (hot melt or the like) to the front side.

  The front plate 12 and the back plate 14 have the same shape (substantially rectangular shape), and they constitute a pair of side surfaces facing each other in the above-described cylinder. Moreover, the 1st side plate 11 and the 2nd side plate 13 are the same shapes (substantially rectangular shape), and these comprise a pair of side surface which faces in the cylinder mentioned above. The first end face plate 15 and the second end face plate 16 each function so as to block the two end faces of the packaging box 10 composed of four side face plates facing each other. 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). It is not restricted to the aspect 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 FIG.

  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 plate 13 and the back plate 14, and a break line 42 is formed at the boundary between the back plate 14 and the connection 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. Note that the break line 41 and the break line 42 also function as a mountain fold line when the above-described cylinder is raised.

  The strength of the break line 41 is set higher than the strength of the break line 42. This is performed using a cartoning machine (box making machine) or the like, and the folding process during manufacturing of the packaging box 10 (when the blank 5 is raised to the above-described cylindrical state, the folding line of the blank 5 (mountain folding line ( In this step, the stress acting on the connecting portion of the break line 41 and the break line 42 is taken into consideration in the step of attaching a crease to the valley fold line). That is, in the above process, the connection piece 17 is bent to 90 ° with respect to the back plate 14, but the back plate 14 is bent to 180 ° with respect to the second side plate 13, and the break line 41 is formed in the above step. This is because the bending angle is larger than the breaking line 42 and the breaking line 41 is required to have higher strength than the breaking line 42. In addition, when both the break line 41 and the break line 42 are perforations, the above-mentioned strength can be changed, for example, by changing the ratio between the entire length of the joint portion and the length of the other portion (the cut portion). Can be adjusted. The bending angle (90 °, 180 °) in the above process is an example, and the bending angle is set to an appropriate value 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 plate 11 on which the first end plate 15 is present in the state where the aforementioned cylindrical body is formed, a flap 111 is provided via a mountain fold line 61, and the first side plate On the side of the face plate 11 where the second end face plate 16 is present in the state where the above-described cylinder is formed, the flaps 112 are respectively extended via the mountain fold lines 62. Further, on the side of the second side plate 13 on which the first end plate 15 is present in the state where the above-described cylinder is formed, the flap 131 is interposed via the mountain fold line 63 and the second side plate 13 is also described above. On the side where the second end face plate 16 is present in a state where the cylindrical body is formed, flaps 132 are respectively extended via the mountain fold lines 64.

  A mountain fold line 35 is formed at the boundary between the back plate 14 and the first end plate 15. A tack 151 is extended through a mountain fold line 36 on the side of the first end face plate 15 facing the side where the back plate 14 is connected. A mountain fold line 37 is formed at the boundary between the back plate 14 and the second end plate 16. A tack 161 is extended through a mountain fold line 38 on the side of the second end face plate 16 facing the side where the back plate 14 is connected.

  As shown in FIG. 4, two cut lines (a cut line 51 and a cut line 52) are formed on the back side of the back plate 14 by leaving a part of the thickness of the blank 5.

  Of these, the cut line 51 is formed adjacent to the break line 41 in parallel along the break line 41 (except for the vicinity of both ends). In order to prevent the strength of the packaging box 10 from decreasing, the cut line 51 is provided at a predetermined distance from the break line 41 except for the vicinity of both ends thereof. As shown in the figure, the cut line 51 is bent in the direction of the long side of the back plate 14 (in the direction of the breaking line 41) at an angle of about 45 ° in the vicinity of both ends, and the tip of each of the cut lines 51 is The corners of the back plate 14 are reached.

  The cut line 52 is formed adjacent to the break line 42 and in parallel along the break line 42 (except for the vicinity of both ends). In order to prevent the strength of the packaging box 10 from decreasing, the cut line 52 is provided at a predetermined distance from the break line 42 except for the vicinity of both ends thereof. As shown in the figure, the cut line 52 is bent in the direction of the long side of the back plate 14 (the direction of the breaking line 42) at an angle of about 45 ° in the vicinity of both ends thereof, and the tip of each of the cut lines 52 is The corners of the back plate 14 are reached.

<Flow from manufacture to disposal of packaging box>
Next, the flow from the manufacture of the packaging box 10 to disposal (assembly → boxing → sealing (sealing) → opening → resealing → disassembly → disposal) will be described with reference to the flowchart shown in FIG.

  When assembling the packaging box 10, first, a cartoning machine or the like is used, and the four side plates of the blank 5 (first side plate 11, front plate 12, second side plate 13, and back plate 14). The connecting piece 17 is bent along the mountain fold line 31, the mountain fold line 32, the mountain fold line 33, the break line 41, and the break line 42 (this step corresponds to the above-described bending step) (S511).

  Subsequently, an adhesive (hot melt or the like) is applied to the surface of the connection piece 17, and the surface of the connection piece 17 is adhered to the back surface of the first side plate 11 so that the break line 42 and the mountain fold line 31 overlap each other. (S512). Note that, for example, the manufacturer of the packaging box 10 delivers the packaging box 10 to the manufacturer of the contents in this state with good transport (transport) efficiency.

  Subsequently, the above-described cylinder is formed by raising the blank 5 three-dimensionally using a cartning machine (box making machine) or the like (S513).

  Subsequently, the contents of the packaging box 10 are boxed in a cylinder (S514), and the packaging box 10 is sealed (sealed) (S515).

  Thereafter, the packaging box 10 reaches the user's hand through a distribution route and the like. The user opens the packaging box 10 and takes out the contents (S516). The packaging box 10 may be resealed for storage of the remaining contents (S517). After use, the packaging box 10 is disassembled (S518) and discarded (S519).

<Disassembly procedure>
Then, the disassembly procedure of the packaging box 10 is demonstrated concretely.

  When disassembling the packaging box 10, first, as shown in FIG. 6, the user picks up the first end face plate 15 with a finger, lifts up the back board 14, and peels off the back board 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 connection piece 17. As described above, the two cut lines (the cut line 51 and the cut line 52) are both cut while leaving a part of the thickness of the blank 5, and the two cut lines are displayed by the user. When the face plate 14 is rolled up, the back plate 14 acts to induce delamination. Specifically, by turning up, the trapezoidal region 611 surrounded by the broken line 41 and the cut line 51 and the trapezoidal region 612 surrounded by the broken line 42 and the cut line 52 are respectively formed on the back plate 14. Delamination occurs. Thereby, 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 connection piece 17. The force required for separation is relieved, and the user can easily dismantle the packaging box 10 without hurting hands.

  In addition, although the robustness of the packaging box 10 falls by providing the breaking line 41 and the breaking line 42, the disassembly of the packaging box 10 is achieved by providing the two cut lines (the cut line 51 and the cut line 52). Since the ease is improved, the strength of the break line 41 and the break line 42 can be increased (ease of disassembly can be secured even if the strength is increased), and the robustness of the packaging box 10 can be secured. it can.

  As described above, the cut line 51 bends in the direction of the long side of the back plate 14 (in the direction of the breaking line 41) at an angle of about 45 ° in the vicinity of both end portions, and all of the tips thereof are corners of the back plate 14. Reached the corner. Further, the cut line 52 is bent in the direction of the long side of the back plate 14 (the direction of the breaking line 42) at an angle of about 45 ° in the vicinity of both end portions thereof, and the tips thereof all reach the corners of the back plate 14. ing. Since both ends of the cut line 51 and the cut line 52 have such a form, the gap between the end face plate (the first end face plate 15 or the second end face plate 16) and the back plate 14 required for the packaging box 10 is obtained. It is possible to secure the connection (connection) strength. Further, since both ends of the cut line 51 and the cut line 52 have such a form, when the user lifts the back plate 14 when the packaging box 10 is disassembled, the above-described delamination is smoothly induced on the back plate 14. Can be made.

  FIG. 7 shows a state in which the packaging box 10 after disassembly (hereinafter also referred to as a paper piece 700) is folded. Thus, the packaging box 10 after disassembly 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 connection piece 17 at the break line 41 and the break line 42, for example, packaging after disassembly. The paper piece 700 of the box 10 does not retain a bag-like structure that causes bulkiness.

  FIG. 8 shows a state in which a plurality of paper pieces 700 of the packaging box 10 after disassembly are stacked, and FIG. 9 shows a state in which a plurality of paper pieces 900 in a conventional packaging box in which a bag-like structure remains on the paper pieces after disassembly. Show. As shown in these drawings, the packaging box 10 of the present embodiment has less bulk in the height direction compared to the conventional example when a plurality of the paper pieces 700 are stacked, and the paper box 700 after disassembly is smaller than the conventional example. It is excellent in storage efficiency (such as storage efficiency of the waste management space) and transport efficiency (such as transport efficiency to the disposal site) of the paper piece 700.

  By the way, the packaging box 10 demonstrated above was a structure (henceforth a three-sheet three-piece structure) which has three flaps in each of the end surface of the cylinder mentioned above. That is, the packaging box 10 described above has a flap 111, a flap 131, and a first end face plate 15 (here, the end face plate is also regarded as a flap) on the end face on the side where the first end face plate 15 of the cylindrical body is present. The same is true in the following description.) The three flaps of the flap 112, the flap 132, and the second end face plate 16 are provided on the end face of the cylindrical body on the side where the second end face plate 16 is present. It was a structure.

  However, as described above, when the packaging box 10 of the present embodiment is disassembled, the back plate 14 has the first side plate 11, the second side plate 13, and the connection piece 17 along the break line 41 and the break line 42. Therefore, the ease of disassembly is not affected by the number of flaps provided in the packaging box 10. Therefore, for example, a packaging box having a similar structure, which has four flaps on one end face and three flaps on the other end face of the two end faces described above (hereinafter, four-sheet three-piece structure). And the above-described three-packed and three-packed packaging box when applied to a packaging box having four flaps (hereinafter referred to as a four-sheet four-sheet structure) on each end face of the cylinder. The effect similar to the case of 10 can be enjoyed.

As shown in these drawings, the packaging box 10 has four flaps (a flap 111, a flap 121, a flap 131, and a first terminal board 15) on one end surface, and three flaps (a flap 112) on the other end surface. , A flap 132, and a second terminal plate 16).

  12 and 13 show an example of the packaging box 10 having a four-sheet / four-sheet structure. 12 is a view of the blank 5 of the packaging box 10 as viewed from the front side of the packaging box 10, and FIG. 13 is a view of the blank 5 of the packaging box 10 as viewed from the back side of the packaging box 10. As shown in these drawings, the packaging box 10 has four flaps (a flap 111, a flap 121, a flap 131, and a first terminal plate 15) on one end surface, and four flaps (a flap 112) on the other end surface. , Flap 122, flap 132, and second terminal board 16).

  In addition, the above description is for making an understanding of this invention easy, and does not limit this invention. The present invention can be changed and improved without departing from the spirit thereof, and the present invention includes equivalents thereof. For example, in the present embodiment, the break lines 41 and 42 and the cut lines 51 and 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 (the first side plate 11, It may be formed on at least one of the front plate 12 and the second side plate 13.
