  The packaging box 10 configured in this way is assembled and used in the following order (1) to (10), for example.

(1) In the blank state shown in FIG. 1, the POP label 27 is attached to the back surface of the top surface portion 151 constituting the cover plate portion 15. FIG. 4 shows a state where the POP label 27 is attached to the back surface of the top surface portion 151. The POP label 27 may be attached either manually or mechanically.

(2) Further, in the blank state shown in FIG. 1, the lid plate portion 15 is bent at the position of the folding line 19 to the inner side (upward) with respect to the bottom wall portion 11a and is raised at a right angle, and the position of the folding line 26 The third reinforcing flap 25 is bent inward at a substantially right angle with respect to the rear peripheral wall portion 11b.

(3) Next, the outer wall surface portions 111d and 111e of the side peripheral wall portions 11d and 11e are bent together with the first reinforcing flaps 22 and the second reinforcing flaps 23 at the positions of the folding lines 19 at substantially right angles to the bottom wall portion 11a. . Thereafter, at the position of the folding line 20, the upper wall surface portions 112d and 112e and the inner wall surface portions 113d and 113e are sequentially bent inward at substantially right angles, and the inner wall surface portions 113d and 113e are respectively disposed inside the space 12. Then, the engagement protrusions 114d and 114e formed at the tips of the inner wall surface portions 113d and 113e are engaged with the engagement holes 111a provided in the bottom wall portion 11a, respectively, and this bending is maintained.

(4) Next, at the position of the folding line 24, the first reinforcing flap 22 and the second reinforcing flap 23 are bent inward at right angles.

(5) Next, at the position of the folding line 20, the outer wall surface portion 111c, the upper wall surface portion 112c, and the inner wall surface portion 113c are bent inward at right angles in order, and the first reinforcing flap 22 and the outer wall surface portion 111c are connected to the inner wall surface portion 113c. The second reinforcing flaps 23 are sandwiched. The inner wall surface portion 113c disposed inside the space 12 presses the engagement protrusions 114c formed at both ends of the inner wall surface portion 113c into the inner surface of the inner wall surface portions 113d and 113e of the side peripheral wall portions 11d and 11e, respectively. The bending is held by the frictional force between the engaging protrusion 114c and the inner wall surfaces 113d and 113e. Thereby, as shown in FIG. 4, the packaging box main-body part 13 side in which the cover board part 15 makes the opening 14 an open state is formed. A plurality of products (bins in the present embodiment) 50 are accommodated in the space 12 of the packaging box body 13 in an aligned manner.

(6) When the operation of storing the product 50 in the packaging box body 13 is completed, the lid plate portion 15 is tilted to the right at the folding curve 31 and the folding plate 32 is folded at the folding curve 32 position. The bent piece portion 152 is tilted inward at a right angle, and the bent piece portion 152 is folded inside the inner wall surface portion 113c. Thereby, the cover plate part 15 is in a state in which the opening 14 is closed. 5 and 6 show this closed state.

(8) Here, in the lock structure portion 16 constituted by the insertion piece 17 and the insertion piece lock hole 18, the insertion piece 17 is provided with a pair of cut portions 28a having a width W1 from the upper end of the front peripheral wall portion 11c. Thus, the insertion piece main body portion 17a is formed so as to be swingable with respect to the packaging box main body portion 13 at the position of the folding line 29, and a part of the insertion piece 17 is reduced to be inclined toward the reduction side. The inclined piece 17b and the insertion tip piece 17c extending from the inclined piece 17b with substantially the same width W2 are integrally provided. On the other hand, the maximum width W3 on the widening side of the insertion lock hole 18 is smaller than the width W1 and larger than the width W2. That is, the widths W1, W2, and W3 are formed in a relationship of W1> W3> W2.

(9) Due to the relationship between the widths W1, W2, and W3, when the insertion piece 17 is inserted into the insertion piece lock hole 18 in the lock structure portion 16, first, both side portions of the insertion tip piece portion 17c are inserted into the insertion lock hole 18. Each of them abuts on a guide side portion 18a formed to be inclined toward the widening side. Then, due to the frictional resistance between both side portions of the insertion tip piece 17c and the guide side portion 18a, the insertion tip piece 17c in the insertion piece 17 is slightly bent and deformed downward (on the bottom wall portion 11a side). The insertion direction on the distal end side of the piece portion 17c is directed in a direction away from the back surface of the top surface portion 151 (on the bottom wall portion 11a side). That is, as shown in FIGS. 7 and 8, the insertion tip piece 17 c gradually approaches the bottom wall portion 11 a that does not interfere with the back surface of the top surface portion 151 of the lid plate portion 15 by the guide side portion 18 a of the insertion lock hole 18. Guide diagonally downward.

(10) When both side portions of the inclined piece portion 17b (or the inserted piece main body portion 17a) of the insertion piece 17 are inserted up to the insertion lock hole 18, the inclined piece portion 17b (or the inserted piece main body of the inserted piece 17). Part of the portion 17 a) bites into both sides of the insertion lock hole 18, and the insertion piece 17 is prevented from coming off by the frictional force between the insertion piece 17 and the insertion lock hole 18, and the lid plate portion 15 is closed and locked. Thereby, the assembly of the packaging box 10 and the packaging of the product 50 are completed. FIG. 7 shows a state where the packaging is completed.

  In addition, when releasing the lock | rock by the lock structure part 16 and opening the cover board part 15, if the insertion piece 17 inserted in the insertion piece lock hole 18 is pulled out from the insertion piece lock hole 18, a lock structure part will be shown. 16 can be unlocked. And if the bending piece part 152 side of the cover plate part 15 is lifted upward and rotated with the folding line 31 as a fulcrum, the cover plate part 15 can be opened.

  Therefore, according to the packaging box 10 of the present embodiment, the lock structure portion 16 that locks the lid plate portion 15 that closes the opening 14 of the packaging box main body portion 13 so as to be opened and closed is the front peripheral wall in the packaging box main body portion 13.

And a slit-like insertion piece lock hole 18 that guides the insertion piece 17 in a direction away from the back surface of the lid plate portion 15 (the back surface of the top surface portion 151). Thus, when the insertion piece 17 of the lock structure portion 16 is inserted into the insertion piece lock hole 18, the insertion piece lock hole 18 guides the insertion direction of the insertion piece 17 in a direction away from the back surface of the cover plate portion 15. Therefore, the insertion piece 17 can be inserted without interfering with the back surface of the cover plate portion 15.

  Further, the insertion piece lock hole 18 of the lock structure portion 16 is provided with a guide side portion 18a that is widened by inclining part of the insertion piece lock hole 18 and inclined toward the widening side, and is opened in a state where the lid plate portion 15 is closed. Since it is formed in a trapezoidal shape that spreads out at the end, it can be easily formed by punching at the same time as punching as a blank.

  Further, even if a sheet printed with a letter or design such as an advertisement or instructions for use, that is, a POP label 27 is attached to the back surface of the cover plate portion 15 (top surface portion 151), the insertion piece 17 is connected to the POP label 27. Since it can be inserted without interference, the packaging box 10 can be assembled by an automatic machine even if the POP label 27 is attached. As a result, it is possible to deal with lots with large production quantities, which contributes to cost reduction. Further, when the POP label 27 is pasted on the back surface of the cover plate portion 15, there is no restriction on the pasting, so that the POP label 27 can be pasted on the entire back surface of the cover plate portion 15. The effect can be used to the maximum.

  Moreover, in the lock structure part 16, the insertion piece 17 is provided so that it can rock | fluctuate with respect to the packaging box main-body part 13 by forming a pair of notch part 28a by width W1 from the upper end of the front peripheral wall part 11c. In addition, a part of the insertion piece 17 is reduced, and an inclined piece part 17b inclined to the reduced width side and an insertion tip piece part 17c extending from the inclined piece part 17b with substantially the same width W2 are integrally provided. . On the other hand, the maximum width W3 on the wide side of the insertion lock hole 18 is smaller than the width W1 and larger than the width W2. Therefore, the lock structure 16 can be easily formed by punching simultaneously when the packaging box 10 is punched as a blank.

  In addition, in this embodiment, although the structure which provided the lock structure part 16 in the front peripheral wall part 11c was disclosed, you may provide in the side peripheral wall parts 11d and 11e.

  Although the insertion piece lock hole 18 has a structure in which the width of a part of the left and right is widened and the guide side part 18a that is inclined to the left and right sides is provided, the inclined guide side part 18a may be provided only on one side. It ’s good.
