The cuts 26f are arranged on both sides of the fold line 90, closer to the front end side of the front insertion piece 26c than the fold line 90, and reach the side end of the front flap 26b.

  A back flap 27b is connected to the upper side of the back plate 27a via a fold line 90, and a back insertion piece 27c is connected to the lower end (upper end in the figure) of the back flap 27b via a fold line 90. Cuts 27f are formed on both sides of the fold line 90 at the boundary between the back flap 27b and the back insertion piece 27c. The cuts 27f are arranged on both sides of the fold line 90 and closer to the distal end side of the back insertion piece 27c than the fold line 90, and reach the side end of the back flap 27b.

  Side flaps 26g are connected to both sides of the front plate 26a via fold lines 90. Side flaps 27g are connected to both sides of the back plate 27a via folding lines 90.

  The front plate 26a and the back plate 27a are bent up from the bottom plate 28a. The front plate 26a and the back plate 27a form a front portion 26 (see FIG. 3) and a back portion 27 (see FIG. 3) of the storage unit 21.

  The side flaps 26g and 27g are bent at a fold line 90 toward the inner surfaces of the front plate 26a and the back plate 27a, respectively. The front flap 26b and the back flap 27b are bent at a fold line 90 toward the outer surface side of the front plate 26a and the back plate 27a, respectively.

  Next, the outer surface plates 22a and 24a are bent from the bottom surface plate 28a, and the inner surface plates 22b and 24b are overlapped and bent on the inner surfaces of the outer surface plates 22a and 24a. The side plate 22 (see FIG. 3) is formed by the outer plate 22a and the inner plate 22b, and the side plate 24 (see FIG. 3) is formed by the outer plate 24a and the inner plate 24b.

  At this time, the left side flap 26g and the left side flap 27g are arranged between the outer plate 22a and the inner plate 22b, and the right side flap 26g and the right side flap 27g are connected to the outer plate 24a and the inner plate 22a. It is arranged between the face plate 24b.

  The folded piece 22d is overlapped on the bottom plate 28a and bent at a fold line 90, and a slit 22f (see FIG. 3) is formed by the cut 22e. The reinforcing plate 28b is overlapped on the bottom plate 28a and bent at a fold line 90, and the convex portion 28c is inserted into the slit 22f. A bottom wall 28 (see FIG. 3) of the storage portion 21 is formed by the bottom plate 28a and the reinforcing plate 28b. At this time, the reinforcing plate 28b is disposed above the folded piece 22d to prevent the inner surface plates 22b and 24b from being lifted. Thus, the inner box 20 shown in FIG. 3 is formed.

  The inner box 20 storing the contents in the storage unit 21 (see FIG. 3) is inserted into the outer box 10 through the opening 11a (see FIG. 2) so that the bottom plate 15 and the bottom wall 28 face each other. . Next, the side surface flaps 12a, 12b, 14a, and 14b of the outer box 10 are bent at a fold line 90 inward.

  Thereafter, the front flap 26b is bent on the side flaps 12a and 14a via the folding line 90, and the front insertion piece 26c is inserted between the bottom plate 15 of the outer box 10 and the bottom wall 28 of the inner box 20. . Further, the back flap 27b is bent on the side flaps 12b and 14b via the folding line 90, and the back insert piece 27c is inserted between the bottom plate 15 of the outer box 10 and the bottom wall 28 of the inner box 20. .

  At this time, the claw portions 26e (see FIG. 3) formed at both ends on the base side of the front insertion piece 26c are engaged with the engaging portions 12c and 14c of the side surface flaps 12a and 14a by the cuts 26f. Further, claw portions (not shown) formed at both ends of the base side of the back insertion piece 27c are engaged with the engaging portions 12c and 14c of the side surface flaps 12b and 14b by the cuts 27f. Thereby, the front insertion piece 26c and the back insertion piece 27c are prevented from coming off.

  Thus, the packaging container 1 shown in FIG. 1 is formed. The outer box 10 and the inner box 20 may be bonded using an adhesive tape member or the like.
