  Next, the case where the packaging box 11 is assembled to a semi-finished state (see FIG. 2) will be described. In FIG. 1, first, the lid left and right side wall crease line 52 is folded down so that the lid part right and left side wall 32 overlaps the top plate part 31, and the folding flap crease line 54 is valley folded (in the state of FIG. And the folding flap 34 is folded back so as to overlap the left and right side walls 32 of the lid. Next, the connecting flap fold line 55 is valley-folded and folded so that the connecting flap 35 overlaps the lid front side wall 33, the lid front side wall crease line 53 is valley-folded, and the lid front side wall 33 is the top plate portion. 31 and the connecting flap 35 is folded back so as to overlap the folding flap 34. A contact portion between the connecting flap 35 and the folding flap 34 is fixed by a connecting flap fixing portion 61.

  1, the support flap fold line 49 is folded with respect to the rear side wall 23 so as to raise the support flap 29, and the rear side wall 23 also has the rear side wall crease line 42 in FIG. It is folded so that it is folded and raised with respect to the bottom plate 21. The left and right side walls 24 are bent so that the left and right side wall crease lines 43 are folded and raised with respect to the bottom plate 21. In this state, the support flap 29 and the left and right side walls 24 overlap with each other, and the portion where the support flap 29 and the left and right side walls 24 abut is fixed by the left and right side wall fixing portions 64.

  As for the front side wall 22 of the box body 14, in FIG. 1, the side flap fold line 45 is folded so that the side flap 26 overlaps the front side wall 22, and the sandwiching flap fold line 44 is folded and pinched.

The insertion flap 27 is folded so that the insertion flap fold line 46 is valley-turned toward the inside of the packaging box 11, and the upper flap 28 is valley-folded at the upper flap crease line 47 so as to go inside the packaging box 11. Bend it.

  Subsequently, the front side wall crease line 41 is valley-folded so that the front side wall 22 rises with respect to the bottom plate 21, and is connected to the left and right side walls 24 in a gap formed by the side flaps 26 and the sandwiching flaps 25. As shown in FIG. 3, the box body 14 is assembled by inserting and holding the insertion flap 27. Thus, since the assembly of the box body 14 is completed simply by raising the left and right side walls 24, the rear side wall 23, and the front side wall 22 from the semi-finished state, the assembly of the box body 14 is easy.

  The box body 14 is assembled, and the article 81 is stored in the storage portion 12 in a state where the lid front side wall 33 is not raised with respect to the top plate portion 31. In the state of FIG. 3, the lid front side wall 33 is not raised with respect to the top plate portion 31, and therefore the lid front side wall 33 does not get in the way when the article 81 is inserted from the insertion port 74. Easy to store.

  After the article 81 is stored in the storage unit 12 and a cake or the like is stored inside the box body 14, the lid unit 15 is subsequently assembled. As shown in FIG. 4, the lid portion 15 causes the lid portion left and right side walls 32 to be raised with respect to the top plate portion 31, and returns the folded folding fold line 54 from the bent state to the original state. By doing so, the ends of the lid left and right side walls 32 are connected to the lid front side wall 33 by the folding flaps 34 and the connecting flaps 35. Stand up against. In this state, the state in which the lid front side wall 33 and the lid left and right side walls 32 stand up with respect to the top plate part 31 is maintained.

  And the state which accommodated the articles | goods 81 in the accommodating part 12, and closed the cover part 15 with respect to the box main body 14 is shown in FIG. In this state, a cross section taken along line 6-6 of the storage portion 12 of the packaging box 11 is as shown in FIG. In a state in which the packaging box 11 is assembled in a three-dimensional form from the flat-shaped development formed body 13, the rear side wall 23 as the second surface is bent with respect to the top plate portion 31 as the first surface. From a state where the top plate portion 31 and the rear side wall 23 of the packaging box 11 are firmly attached to the top plate portion 31 without looseness, the top plate portion 31 and the rear side wall 23 are appropriately bent. As a result, a gap is secured between the top plate portion 31 of the packaging box 11, the inner side surface of the rear side wall 23, and the sheet member 71, so that a sufficient space for storing the article 81 is provided inside the storage portion 12. Can be secured.

  In this embodiment, the fixing portion 73a and the fixing portion 73b of the fixing portion 73 are formed continuously. However, the fixing portion 73a and the fixing portion 73b constituting the fixing portion 73 are not necessarily formed continuously. Even if it is not made, what is necessary is just to divide the inside and the outside of the storage part 12 substantially. For example, even if the adhering portion 73a and the adhering portion 73b are formed with a space therebetween, the adhering portion 73 is connected to the inside and the outside of the accommodating portion 12 as long as the article 81 in which the interval is stored cannot be inserted. It will be virtually divided.

  In addition, the fixing portion 73a as the first fixing portion is formed in a direction orthogonal to the insertion direction of the article 81 into the insertion port 74, but a substantial depth in the insertion direction of the article 81 into the insertion port 74. It may be formed on the side. That is, if it is formed on the substantial back side in the insertion direction of the article 81 into the insertion port 74, for example, the fixing portion 73 a is formed obliquely with respect to the insertion direction of the article 81 into the insertion port 74. Alternatively, the fixing portion 73a may be formed in a curved shape.

  Further, the fixing portion 73a as the first fixing portion is formed on the rear side wall 23 as the second surface. However, the entire fixing portion 73a may not be formed on the rear side wall 23, and one of the fixing portions 73a. The part should just be formed in the rear side wall 23. FIG. If even a part of the fixing portion 73 a is formed on the rear side wall 23, when the rear side wall 23 is bent with respect to the top plate portion 31, the sheet member 71 is separated from the top plate portion 31 and the rear side wall 23 of the packaging box 11. From the state of being affixed to the top plate portion 31 and the rear side wall 23, the state is bent between the top plate portion 31 and the rear side wall 23. Therefore, for example, the fixing portion 73a may be formed obliquely so as to intersect the lid connecting fold line 51 as the first valley fold, or may be formed in a curved shape, and at least a part of the fixing portion 73a.
