Thereby, the first half-cut line 21 and the second half-cut line 22 on the front plate 3 are continuous with the first half-cut line 21 and the second half-cut line 22 on the first top plate 2, respectively.

  The distance D2 between the first half-cut line 21 and the second half-cut line 22 of the opening start portion 35 is smaller than the distance D1 between the first half-cut line 21 and the second half-cut line 22 excluding the opening start portion 35. Is becoming In this embodiment, the distances D1 and D2 are about 4 mm and about 2 mm, respectively. Since the first half-cut line 21 and the second half-cut line 22 do not overlap in a top view, the first half-cut line 21 and the second half-cut line 22 are not formed when the first half-cut line 21 and the second half-cut line 22 are formed. Penetration with the line 22 can be prevented.

  The recess 31 is formed by pressing the front surface (outer surface) of the front plate 3 with a press or the like. A first cutting portion 71, a second cutting portion 72, and a cut 73 are formed on the cover plate 7. The protruding portion 74 is formed by pressing from the inner surface side of the cover plate 7 toward the outer surface side by a press or the like.

  Protrusions 120 are formed near the front plate 3 on the side flaps 82, 92, 84, 94, respectively. Each convex portion 120 is formed by pressing the side surface flaps 82, 92, 84, 94 from the inner surface side to the outer surface side by a press or the like.

  A plurality of (five in this embodiment) adhesives, which are half-cut perforations extending in the up-down direction (the left-right direction in FIG. 2), on the side of the side flaps 82, 92, 84, 94 that is away from the front plate 3. The holding part 130 is formed.

  A plurality of (17 in this embodiment) adhesive holding portions 131 formed of half-cut perforations extending in the front-rear direction are formed at the front ends (the right end and the left end in FIG. 5) of the side flaps 85, 95. It The adhesive holding portion 131 is arranged from the upper end portion to the lower end portion of the side surface flaps 85 and 95, and is arranged at the central portion in the front-rear direction when forming the side surface portions 8 and 9 described later.

Then, the size allowance flap 25 is bent toward the inner surface side of the first top plate 2 through the fold line 110, and the outer surface of the size allowance flap 25 and the inner surface of the upper end of the back plate 5 are bonded together with an adhesive. ..

  Then, the second top plate 6 is bent so as to overlap with the first top plate 2 through the fold line 110, and the covering plate 7 is bent through the fold line 110 so as to overlap with the upper part of the front plate 3. After that, the cover plate 7 is adhered to the outer surface of the upper part of the front plate 3 with an adhesive. At this time, the region between the second half-cut lines 22 of the front plate 3 adjacent to the upper portion of the grip portion 75 is adhered to the cover plate 7 with the adhesive 300. The second top plate 6 is not adhered to the first top plate 2.

  As a result, the storage box 1 in which both side surfaces of the body portion 10 are open is formed. Then, as shown in FIG. 4, the storage box 1 is flattened by the folding of the folding portions 23 and 45. At this time, the first top plate 2 and the front plate 3 closely face each other, and the bottom plate 4 and the back plate 5 closely face each other.

  The storage box 1 is transported and stored in a flatly crushed state with a small volume (folded body). Thereby, the transportation cost and the storage cost of the storage box 1 can be reduced.

  At the place where the contents are stored in the body portion 10, the storage box 1 in a flatly crushed state is set in a packaging machine (not shown). The wrapping machine presses the folding parts 23 and 45 from the state shown in FIG. 4 in the direction of approaching each other. As a result, the body portion 10 is raised so that the first top plate 2, the second top plate 6 and the bottom plate 4 are substantially perpendicular to the front plate 3 and the back plate 5.

  After that, the side surface flaps 92 and 94 are bent toward the inner surface sides of the first top plate 2 and the bottom plate 4 through the folding lines 110, respectively. After the adhesive is applied to the adhesive holding portions 130 of the side flaps 92, 94, the side flaps 95 are folded along the folding lines 110 so as to overlap the side flaps 92, 94. Then, after the adhesive is applied to the adhesive holding portion 131 of the side flap 95, the side flap 93 is folded along the folding line 110 so as to overlap the side flap 95. As a result, the side surface flaps 92, 94 are adhered to the side surface flaps 95 with an adhesive, and the side surface flaps 93 are adhered to the side surface flaps 95 with an adhesive to form the side surface portion 9. At this time, the left side surface of the body portion 10 is closed.

  Then, the contents are stored in the body 10 through the opening (not shown) on the right side with the right side of the body 10 facing upward.

  After the contents are stored in the body portion 10, the side surface flaps 82 and 84 are bent toward the inner surfaces of the first top plate 2 and the bottom plate 4 through the folding lines 110, respectively. After the adhesive is applied to the adhesive holding portions 130 of the side flaps 82 and 84, the side flap 85 is bent along the folding line 110 so as to overlap the side flaps 82 and 84. Then, after the adhesive is applied to the adhesive holding portion 131 of the side flap 85, the side flap 83 is folded along the folding line 110 so as to overlap the side flap 85. As a result, the side surface flaps 82 and 84 are adhered to the side surface flap 85 with an adhesive, and the side surface flap 83 is adhered to the side surface flap 85 with an adhesive to form the side surface portion 8. As described above, the right side surface of the body portion 10 is closed, and the storage box 1 in which the contents are stored is formed as shown in FIG.

  At this time, the adhesive holding portion 130 easily holds the adhesive on the side surface flaps 82, 84, 92, 94, and the adhesive holding portion 131 easily holds the adhesive on the side surface flaps 85, 95. It Thereby, the side surface portions 8 and 9 can be reliably formed. Further, the protrusion 120 can reduce the gap between the side flaps 92, 94 and the side flap 93 and the gap between the side flaps 82, 84 and the side flap 83.

  The side surface portion 9 may be formed after the side surface portion 8 is formed and the contents are stored in the body portion 10.

  FIG. 5 shows a perspective view of the storage box 1 after opening. When a user who purchases a product whose contents are stored in the storage box 1 holds the holding portion 75 and pulls it upward, the first cutting portion 71 and the second cutting portion 72 (see FIG. 1 for both). The cover plate 7 is fractured along. At this time, a fracture surface BR (see FIG. 3) is formed by peeling between the first half-cut line 21 and the second half-cut line 22, and the upper portion of the front plate 3 and the first top plate 2 are broken to open. The surface 10a is formed. As a result, the inner lid portion 20 that opens and closes the upper surface of the body portion 10 is formed by breaking the upper portion of the front plate 3 and the first top plate 2. Further, the outer cover portion 60 that is opened and closed integrally with the second top plate 6 is formed by breaking the covering plate 7. As a result, the storage box 1 is opened, and the user can take out the contents from the inside of the body 10 through the opening surface 10a. At this time, the grip portion 75 is arranged on the outer lid portion 60, and the outer lid portion 60 is bonded to the inner lid portion 20 with the adhesive 300 above the grip portion 75. Further, the protruding portion 74 is arranged on the outer surface above the grip portion 75 of the outer lid portion 60.

  At this time, the distance D2 (see FIG. 2) between the first half-cut line 21 and the second half-cut line 22 of the unsealing start portion 35 on the front plate 3 near the grip portion 75 excludes the unsealing start portion 35. It is smaller than the distance D1 (see FIG. 2) between the first half-cut line 21 and the second half-cut line 22. As a result, when the user grips the gripping portion 75 and pulls the gripping portion upward, peeling easily occurs between the first half-cut line 21 and the second half-cut line 22 of the opening start portion 35, and the outer substrate It is possible to prevent peeling of only the material layer 11 (see FIG. 3). Therefore, the storage box 1 can be easily opened, and the convenience of the storage box 1 can be improved.
