Further, flap panels 32A and 32B are provided continuously on both short sides of the first inner panel 16 via a tenth folding auxiliary line (ruled line) L10.

  In addition, rectangular projecting portions 15A and 15B are provided at both ends of the first frame panel 15 so as to project outward in the perpendicular direction. As will be described later, the overhang portions 15A and 15B overlap with both ends 22A and 22B of the second frame panel 22 when the framed box 10 is assembled. In addition, the width | variety of the short side direction of the 1st frame panel 15 and the 2nd frame panel 22 is substantially the same.

  Furthermore, stepped cuts 16 </ b> C are provided at both ends (on the short side) of the first inner panel 16. On the other hand, stepped protrusions 23A and 23B are provided at both ends (on the short side) of the second inner panel 23, respectively. As will be described later, when the framed box 10 is assembled, the protrusions 23A and 23B are fitted into the gaps 16A and 16B formed by the cuts 16C, and the first double side surface 11 and the second double side surface 12 are connected. It is for locking in a state of being adjacent at a substantially right angle.

  The first inner panel 16 has a plurality of notches C as shown in FIGS. The notches C are provided at regular intervals so as to cut the fourth folding auxiliary line L4.

Further, the upper end of the bending assisting piece 17A is disposed slightly closer to the bottom panel 13 than the first bending assisting line L1. In such a state, an adhesive is applied to the glue margin panel 17 and bonded to the bottom panel 13.

  Next, the first outer panel 14 is pushed up from the back side (in FIG. 2). Then, the bottom panel 13 and the first outer panel 14 are bent at a substantially right angle along the first folding auxiliary line L1, and the first frame panel 15 and the first inner panel 16 are bent along the third folding auxiliary line L3. The first inner side panel 16 and the adhesive margin panel 17 are bent at a substantially right angle at the fourth folding auxiliary line L4 to form the first double side surface 11. Such an operation is performed on the left and right sides of the blank paper B to form the pair of first double side surfaces 11 and 11 (FIG. 4B).

  Subsequently, the flaps 31A and 32A of the first double side surfaces 11 and 11 are bent inward at substantially right angles at the ninth folding auxiliary line L9 and the tenth folding auxiliary line L10, respectively. At this time, since the notches 16A are formed in a step shape, gaps 16A and 16B are formed between the flaps 32A and 32B and the first inner panel 16 (see FIG. 2). And the 2nd outer side panel 21 is bent with respect to the bottom panel 13 in the 5th bending auxiliary line L5, and is made substantially upright. Further, the second frame panel 22 is bent at a substantially right angle with respect to the second outer panel 21 along the sixth folding auxiliary line L6. At this time, both ends 22A and 22B of the second frame panel 22 are placed on the overhang portions 15A and 15B of the first frame panel 15, respectively.

  Then, the second inner panel 23 is bent at a substantially right angle with respect to the second frame panel 22 along the seventh folding auxiliary line L7, and the protruding portions 23A and 23B are inserted into the gaps 16A and 16B to be locked. Furthermore, the second double side surface 12 is formed by bending the extended panel 24 at a substantially right angle to the second inner panel 23 by the eighth folding auxiliary line L8 (FIG. 5A). . Such an operation is performed on the front and back of the blank paper B to form a pair of second double side surfaces 12 and 12 to complete the framed box 10 (FIG. 5B). When the second double side surface 12 is formed, the second outer panel 21 and the second inner panel 23 have substantially the same height. Further, the first double side surface 11 and the second double side surface 12 are locked by the projecting portions 23A and 23B and the gaps 16A and 16B, and can maintain a state of being adjacent substantially at right angles. Further, the extended panel 24 may be bonded to the bottom panel 13.
