As a result, the bottom portion 140 of the packing device 100 can be easily assembled.

  With reference to FIGS. 3A and 3B, the protrusion 150 and the opening 122 will be further described. FIG. 3A is an enlarged view of the vicinity of the protrusion 150. FIG. 3B is an enlarged view of the vicinity of the opening 122.

  In FIG. 3A, the length d1 indicates the length along the boundary B between the first side portion 110a at the tip of the insertion portion 154 and the inner flap 120a. In the present specification, the boundary B between the first side portion 110a and the inner flap 120a may be simply referred to as the boundary B. In this embodiment, the boundary B is along the X-axis direction. In FIG. 3A, the length d2 indicates the length along the boundary B of the base end portion 1521. In FIG. 3A, the length d3 indicates the length along the boundary B of the intermediate portion 1522. In FIG. 3A, the length d4 indicates the length along the boundary B at the rear end of the insertion portion 154. In FIG. 3A and FIG. 3B, the length d5 indicates the length along the boundary B of the main body portion 1221. In FIG. 3B, the length d6 indicates the length along the boundary B of the connecting portion 1222.

  As shown in FIG. 3A, the holding portion 152 has a base end portion 1521 and an intermediate portion 1522. The base end portion 1521 faces the inner flap 120a. The size of the opening 122 is larger than the size of the protrusion 150. Therefore, a gap is formed between the inner flap 120a and the protrusion 150. The intermediate portion 1522 is connected to the insertion portion 154 and the base end portion 1521. The length d1 along the boundary B at the tip of the insertion portion 154 is shorter than the length d4 along the boundary B at the rear end of the insertion portion 154.

  As shown in FIG. 3B, the opening 122 has a main body portion 1221 and a connecting portion 1222.

  The main body portion 1221 has a rectangular shape. The connecting portion 1222 has a rectangular shape. The connecting portion 1222 is connected to the main body portion 1221. The connection part 1222 is connected to the first side part 110a. The length d5 of the body portion 1221 along the boundary B is longer than the length d6 of the connecting portion 1222 along the boundary B.

  The inner flap 120a has a support portion 124. When the packing tool 100 is assembled, the support portion 124 supports the first outer flap 130a and the second outer flap 130b. The support part 124 is connected to the first side part 110a. The support portion 124 is adjacent to the opening 122.

  As shown in FIGS. 3A and 3B, the length d3 of the intermediate portion 1522 along the boundary B is shorter than the length d5 of the main body portion 1221 along the boundary B.

  The length d2 of the base end portion 1521 along the boundary B is equal to the length d6 of the connecting portion 1222 along the boundary B.

  As described above with reference to FIGS. 2, 3A and 3B, the opening 122 is formed in the inner flap 120a. The size of the opening 122 is larger than the size of the protrusion 150. Therefore, a gap is formed between the protrusion 150 and the inner flap 120a. Therefore, when the inner flap 120a is bent, friction generated between the inner flap 120a and the protrusion 150 can be reduced. Therefore, when the inner flap 120a is bent, the force by which the protrusion 150 stands can be made stronger than the force by which the inner flap 120a winds the protrusion 150. Therefore, when the inner flap 120a is bent, the protrusion 150 is held in a self-supporting state.

  Further, the inner flap 120a has a support portion 124. When the packing tool 100 is assembled, the support portion 124 supports the first outer flap 130a and the second outer flap 130b. Therefore, when the packing tool 100 is assembled, it is possible to prevent the first outer flap 130a and the second outer flap 130b from sinking.

  In addition, the protrusion 150 has a pressing portion 152 and an insertion portion 154. Further, the pressing portion 152 presses the first outer flap 130a and the second outer flap 130b. Further, the insertion portion 154 is inserted into the insertion port 160. Therefore, when the insertion portion 154 is inserted into the insertion port 160, the pressing portion 152 presses the first outer flap 130a and the second outer flap 130b. As a result, it is possible to prevent the first outer flap 130a and the second outer flap 130b from rising.

  The length d1 along the boundary B at the tip of the insertion portion 154 is shorter than the length d4 along the boundary B at the rear end of the insertion portion 154. Therefore, the insertion portion 154 can be smoothly inserted into the insertion port 160.

  An assembling method of the packaging tool 100 will be described with reference to FIGS. 4A, 4B, 5A, and 5B. FIG. 4A, FIG. 4B, FIG. 5A, and FIG. 5B are perspective views showing a method of assembling the packing device 100.

  From the state shown in FIG. 4A, the inner flap 120a is bent toward the + Y direction side as shown in FIG. 4B. An opening 122 is formed in the inner flap 120a. Therefore, even if the inner flap 120a is bent in the + Y direction, the protrusion 150a is held in a self-supporting state. Further, the inner flap 120b is bent toward the −Y direction side. An opening 122 is formed in the inner flap 120b. Therefore, even if the inner flap 120b is bent in the −Y direction, the protrusion 150b is held in a self-supporting state.

  Next, as shown in FIG. 5A, the first outer flap 130a is bent to the + X direction side. Further, the second outer flap 130b is bent toward the −X direction side. As a result, the insertion opening 160 is formed by the first cutout portion 132a and the second cutout portion 132b.

  Next, as shown in FIG. 5B, the protrusion 150a is inserted into the insertion port 160. Further, the protrusion 150b is inserted into the insertion port 160. As a result, the first outer flap 130a and the second outer flap 130b are sandwiched between a part of the inner flap 120a and a part of the inner flap 120b. Therefore, it is possible to prevent the first outer flap 130a and the second outer flap 130b from rising. As a result, the lid surface of the packaging device 100 can be made flat.

  The insertion port 160 will be further described with reference to FIG. 6. FIG. 6 is an enlarged view of the vicinity of the insertion port 160. In FIG. 6, the length d7 indicates the length of the insertion port 160 along the boundary B. In FIG. 6, the length d8 indicates the length from the first cut 134a to the second cut 134b.

  As shown in FIG. 6, a first cut 134a is formed in the first outer flap 130a. The first cut 134a extends from the first cutout 132a. The first cut 134a extends along the X-axis direction. A second cut 134b is formed in the second outer flap 130b. The second notch 134b extends from the second notch 132b. The second cut 134b extends along the X-axis direction. The protrusion 150 is inserted into the insertion port 160, the first cut 134a, and the second cut 134b. Therefore, when the protrusion 150 is inserted into the insertion port 160, it can be easily inserted. Furthermore, it is possible to prevent the protrusion 150 from coming off from the state where the protrusion 150 is inserted into the insertion port 160.
