At this time, the inner plate 16A of the connecting portion 16 is arranged inside, and the outer plate 16B bent outward at the bending line 19 is arranged outside.

Then, the belt portion 20 is pulled out by a cut 21 formed inside the plate surface of the first side surface portion 6, leaving the base end 20a. As a result, the band portion 20 is formed such that the proximal end 20a is connected to the first side surface portion 6 and the distal end 20b side is cantilevered with respect to the first side surface portion 6. As shown in FIG.

In order to engage the belt portion 20 and the openings 22A and 22B to connect the first side surface portion 6 and the connecting portion 16, first, the notch portions 23A and 23B formed at the ends of the connecting portion 16 are fitted with the belt portions. The proximal end 20a side of 20 is fitted. Then, the proximal end 20a side of the belt portion 20 is placed on the inner surface side of the connecting portion 16, and the distal end 20b of the belt portion 20 is inserted from the inner surface side to the outer surface side of the connecting portion 16 into the openings 22A and 22B. Thereby, the belt portion 20 and the openings 22A and 22B are engaged. In this state, the belt portion 20 sandwiches the connecting portion 16 with the first side portion 6, and the first side portion 6 and the connecting portion 16 are fixed to each other.

Assembling the spacer 3 and installing it on the main body 2 will be described below.
A second reinforcing portion 32 connected to both ends of the first reinforcing portion 31 of the spacer 3 is bent inward by a fourth bending line 35 . As a result, when the spacer 3 is installed on the main body 2, the angle formed by the first reinforcing portion 31 and the second reinforcing portion 32 becomes 90°, and the spacer 3 can have an L-shape.

In addition, the second slope portion 33 is bent inward by the fifth folding line 36 between the two third cuts , and the second slope portion 33 is inclined with respect to the first reinforcing portion 31. becomes. Thus, when the spacer 3 is installed on the main body 2, the first reinforcing portion 31 is installed along the inner surface of the second side surface portion 7, and the second reinforcing portion 32 is installed along the inner surface of the first side surface portion 6. installed along. Also, the second slope portion 33 is installed to be inclined with respect to the bottom surface portion 5 .

As described above, inside the body portion 2 , the first slope portion 8 is formed on a set of two opposing sides among the four sides of the bottom portion 5 , and the other pair of opposing sides of the four sides of the bottom portion 5 is formed. A second slope portion 33 is formed on two sides. The first slope portion 8 has an inclination that increases in height from the bottom surface portion 5 toward the first side surface portion 6, and the second slope portion 33 extends from the bottom surface portion 5 to the first reinforcing portion 31 and the second side surface portion. It has an increasing slope toward 7.

When the design surface side of a panel member such as a decorative panel of a ceiling-embedded air conditioner is not a simple flat surface but an inclined surface is formed toward each side from the central part, the first cushioning material is not installed separately. The slope portion 8 and the second slope portion 33 can prevent the panel member from tilting or shifting within the packaging container 1 .

Next, the lid portion 4 and the flaps 9 formed on the body portion 2 covering the four sides of the lid portion 4 will be described.
The flap 9 is connected to the first side portion 6 via the bent portion 24 and the second side portion 7 via the bent portion 25 in the body portion 2 according to the present embodiment. and the second flap 9B.

When the packaging container 1 is assembled, the first flap 9A and the second flap 9B are adjacent. At this time, the side end portion 9A-a of the first flap 9A and the side end portion 9B-a of the second flap 9B are butted against each other, and the side end portion 9A-a of the first flap 9A The side edge 9B-a of the second flap 9B is formed in a direction (for example, 45°) inclined with respect to the longitudinal direction of the side surface 6, and the side end 9B-a of the second flap 9B is inclined in a direction (for example, 45°) with respect to the longitudinal direction of the second side surface 7. °).

The first flap 9A can be folded with respect to the first side surface portion 6 at the folding portion 24, and the second flap 9B can be folded with respect to the second side surface portion 7 at the folding portion 25 ( sixth folding portion ) . Since the side end portion 9A-a of the first flap 9A and the side end portion 9B-a of the second flap 9B are butted against each other, the first side portion 6 and the second side portion 7 , the first flap 9A and the second flap 9B form the corners of the packaging container 1 .

A bent portion 26 is formed at the side end portion 9A-a of the first flap 9A, and a first insertion portion 27 is connected to the first flap 9A via the bent portion 26. As shown in FIG. A bent portion 28 is formed at the side end portion 9B-a of the second flap 9B, and the second insertion portion 29 is connected to the second flap 9B via the bent portion 28. As shown in FIG. As a result, the first insertion portion 27 can be bent at the bent portion 26 formed at the side end portion 9A-a of the first flap 9A, and the first insertion portion 27 can be bent at the side end portion 9B-a of the second flap 9B. The second insertion portion 29 can be bent at the bent portion 28 .

An insertion hole 41 is formed in the lid portion 4 , and the first insertion portion 27 and the second insertion portion 29 are inserted into the insertion hole 41 . In this state, the first flap 9A and the second flap 9B are fixed to the lid portion 4. As shown in FIG.

An insertion portion 51 is connected to the central portion of the front end portion 9A-b of the first flap 9A. An insertion portion 52 is connected to the central portion of the front end portion 9B-b of the second flap 9B. An insertion hole 42 is formed in the lid portion 4 , and the insertion portion 51 and the insertion portion 52 are inserted into the insertion hole 42 . As a result, the intermediate portion of the first flap 9A and the intermediate portion of the second flap 9B are fixed to the lid portion 4 so that no gap is formed.

A front end portion 9A-b of the first flap 9A and a front end portion 9B-b of the second flap 9B have an arc shape. Therefore, the tips on both sides of the front end portion 9A-b of the first flap 9A and the tip of the insertion portion 51 are arranged on the same straight line. Therefore, when forming the insertion portion 51, the insertion portion 51 is not at a protruding position, but rather at a position protruding from the line connecting the ends of the front ends 9A-b of the first flap 9A, but inside the line. formed in Therefore, waste material can be reduced when forming the blank.

Further, after a part of another packaging container 1 is placed on top of the packaging container 1, when the packaging container 1 placed on top is slid, the corner of the packaging container 1 placed on top of the first flap 9A and the front end 9B-b of the second flap 9B. Since the front end portion 9A-b of the first flap 9A and the front end portion 9B-b of the second flap 9B are arc-shaped, the corners of the packing container 1 placed on the first flap It is directed toward the center of the front end 9A-b of 9A or the center of the front end 9B-b of the second flap 9B. Insertion portions 51 and 52 are formed at the center of the front end portion 9A-b of the first flap 9A and the center of the front end portion 9B-b of the second flap 9B. The corner rides over the inserts 51 and 52 .

Therefore, in the case of the present embodiment, compared to the case where the front end portion 9A-b of the first flap 9A and the front end portion 9B-b of the second flap 9B are formed in a linear shape instead of an arc shape, the upper The packing container 1 placed on the top is smoothly slid without being caught by the flaps 9A and 9B, and a plurality of packing containers 1 can be easily superimposed.
