[0025] The smoking device D further includes a first door 210 and a second door 220. The first door 210 has a first door body 211. The first door body 211 is a plate connected to the first edge 111 of the first opening 101 in a manner that allows it to be folded freely, and is made of thick paper such as corrugated cardboard. The second door 220 has a second door body 221. The second door body 221 is a plate connected to the second edge 121 of the first opening 101 in a manner that allows it to be folded freely, and is made of thick paper such as corrugated cardboard.

[0026] The first door main body 211 of the first door 210 and the second door main body 221 of the second door 220 are capable of freely opening and closing the first opening 101. More specifically, the first door main body 211 is capable of freely opening and closing an area on the Z-direction side of the first opening 101, and the second door main body 221 is capable of freely opening and closing an area on the Z'-direction side of the first opening 101. In a state in which the first door main body 211 of the first door 210 and the second door main body 221 of the second door 220 close the first opening 101, the sum of the dimension of the first door main body 211 in the Z-Z' direction and the dimension of the second door main body 221 in the Z-Z' direction is approximately the same as the linear distance in the Z-Z' direction from the first edge 111 of the first opening 101 to the second edge 121 of the first opening 101.

[0027] The first door body 211 has a first abutment portion 211a and a second abutment portion 211b. When the first door body 211 closes the area on the Z-direction side of the first opening 101, the first abutment portion 211a and the second abutment portion 211b can be configured to abut against portions on the Z-direction side of the third edge 131 and the fourth edge 141 of the first opening 101. The second door body 221 has a first abutment portion 221a and a second abutment portion 221b. When the second door body 221 closes the area on the Z'-direction side of the first opening 101, the first abutment portion 221a and the second abutment portion 221b can be configured to abut against portions on the Z'-direction side of the third edge 131 and the fourth edge 141 of the first opening 101.

[0028] It is possible for the first door body 211 to further have at least one of the first protrusion 211c and the second protrusion 211d. In this case, the dimension of the first door body 211 in the X-X' direction is greater than the linear distance in the X-X' direction from the third edge 131 of the first opening 101 to the fourth edge 141 of the first opening 101.

[0029] The first protrusion 211c extends from the first abutment portion 211a toward the X direction. For example, the first protrusion 211c may be an end portion of the first door main body 211 in the X direction and located on the X direction side of the first abutment portion 211a, or may be a convex portion extending from the first abutment portion 211a toward the X direction. When the first door main body 211 closes the area of ​​the first opening 101 on the Z direction side, the first protrusion 211c protrudes toward the X direction beyond the third edge 131 of the first opening 101. The second protrusion 211d extends from the first abutment portion 211a toward the X' direction. For example, the second protrusion 211d may be an end portion of the first door main body 211 in the X' direction and located on the X' direction side of the second abutment portion 211b, or may be a convex portion extending from the second abutment portion 211b toward the X' direction. When the first door body 211 closes the area on the Z-direction side of the first opening 101, the second protrusion 211d protrudes further in the X'-direction than the fourth edge 141 of the first opening 101. At least one of the first protrusion 211c and the second protrusion 211d functions as a handle that is used by the user when opening or closing the area on the Z-direction side of the first opening 101 with the first door body 211.

[0030] The first protrusion 211c and the second protrusion 211d can be omitted. In this case, the dimension of the first door body 211 in the X-X' direction may be approximately the same as the linear distance in the X-X' direction from the third edge 131 of the first opening 101 to the fourth edge 141 of the first opening 101.

[0031] The second door body 221 may further include at least one of the first protrusion 221c and the second protrusion 221d. In this case, the dimension of the second door body 221 in the X-X' direction is greater than the linear distance in the X-X' direction from the third edge 131 of the first opening 101 to the fourth edge 141 of the first opening 101.

[0032] The first protrusion 221c extends from the first abutment portion 221a toward the X direction. For example, the first protrusion 221c may be an end portion of the second door main body 221 in the X direction and located on the X direction side of the first abutment portion 221a, or may be a convex portion extending from the first abutment portion 221a toward the X direction. When the second door main body 221 closes the area on the Z' direction side of the first opening 101, the first protrusion 221c protrudes toward the X direction beyond the third edge 131 of the first opening 101. The second protrusion 221d extends from the first abutment portion 221a toward the X' direction. For example, the second protrusion 221d may be an end portion of the second door main body 221 in the X' direction and located on the X' direction side of the second abutment portion 221b, or may be a convex portion extending from the second abutment portion 221b toward the X' direction. With the second door body 221 closing the area on the Z'-direction side of the first opening 101, the second protrusion 221d protrudes further in the X'-direction than the fourth edge 141 of the first opening 101. At least one of the first protrusion 221c and the second protrusion 221d functions as a handle that is used by the user when opening or closing the area on the Z'-direction side of the first opening 101 with the second door body 221.

[0033] The first protrusion 221c and the second protrusion 221d can be omitted. In this case, the dimension of the second door body 221 in the X-X' direction may be approximately the same as the linear distance in the X-X' direction from the third edge 131 of the first opening 101 to the fourth edge 141 of the first opening 101.

[0034] The first door 210 may further have a first flap 212. The first flap 212 is a plate connected to the free end of the first door main body 211 in a manner that allows it to be folded freely, and is made of thick paper such as corrugated cardboard. The second door 220 may further have a second flap 222. The second flap 222 is a plate connected to the free end of the second door main body 221 in a manner that allows it to be folded freely, and is made of thick paper such as corrugated cardboard.

[0035] When the first door body 211 and the second door body 221 close the first opening 101, the first flap 212 is bent relative to the first door body 211 at a free end of the first door body 211 and extends in the Y' direction, and the second flap 222 is bent relative to the second door body 221 at a free end of the second door body 221 and extends in the Y' direction. In this state, the first flap 212 and the second flap 222 abut against each other. More specifically, the surface of the first flap 212 facing the Z' direction and the surface of the second flap 222 facing the Z direction are in surface contact. This surface contact between the first flap 212 and the second flap 222 maintains the first door body 211 and the second door body 221 in a state in which the first opening 101 is closed. Note that the first flap 212 and / or the second flap 222 may be omitted.

[0036] The smoking device D may further include a first folded portion 310 and a second folded portion 320. The first folded portion 310 is connected to a third edge 131 of the first opening 101 of the main body 100, and is folded back in the Y′ direction to be inserted into the main body 100 through the first opening 101. The second folded portion 320 is connected to a fourth edge 141 of the first opening 101 of the main body 100, and is folded back in the Y′ direction to be inserted into the main body 100 through the first opening 101. For example, the first folded portion 310 may have a first portion 311 and a second portion 312, and the second folded portion 320 may have a first portion 321 and a second portion 322.

[0037] The first portion 311 is a plate connected to the third edge 131 in a manner that allows it to be folded freely, and is made of thick paper such as corrugated cardboard. The first portion 321 is a plate connected to the fourth edge 141 in a manner that allows it to be folded freely, and is made of thick paper such as corrugated cardboard. The first portion 311 is folded toward the third wall 130, with the third edge 131 as the boundary, and in this folded state, extends toward the first portion 321. The first portion 321 is folded toward the fourth wall 140, with the fourth edge 141 as the boundary, and in this folded state, extends toward the first portion 311. In other words, the first portion 311 and the first portion 321 extend toward each other in a folded state. In a folded state, first portion 311 may extend in the X' direction from third edge 131 (see FIGS. 2A to 2C), may extend in a first oblique direction from third edge 131 that includes components in the X' direction and the Y' direction (not shown), or may extend in a second oblique direction from third edge 131 that includes components in the X' direction and the Y direction (not shown).

[0051] The dimension of the third portion 313 in the Z-Z' direction may be approximately the same as or larger than the dimension of the interior of the main body portion 100 in the Z-Z' direction (i.e., the distance from the first wall 110 to the second wall 120 in the Z-Z' direction). In either case, the third portion 313 is interposed between the first wall 110 and the second wall 120 in the Z-Z' direction when bent in any of the ways described above. That is, the third portion 313 abuts against the first wall 110 from the Z' direction side and abuts against the second wall 120 from the Z direction side. The dimension of the third portion 323 in the Z-Z' direction may be approximately the same as or larger than the dimension of the interior of the main body portion 100 in the Z-Z' direction (i.e., the distance from the first wall 110 to the second wall 120 in the Z-Z' direction).

In other words, the third portion 313 and / or the third portion 323 may be configured not to be interposed between the first wall 110 and the second wall 120 in the Z-Z' direction. Note that the third portion 313 and / or the third portion 323 may be omitted.

In Figures 1A to 6B, at least one extension 313a and at least one extension 323a are provided in threes, but the numbers can be changed as desired.

[0054] It is to be noted that at least one extension portion 313a and / or at least one extension portion 323a may be omitted. If the second portion 312 does not extend to the at least one closure plate of the fifth wall 150, the third portion 313 does not abut against the at least one closure plate of the fifth wall 150 in the folded state. If the second portion 322 does not extend to the at least one closure plate of the fifth wall 150, the third portion 323 does not abut against the at least one closure plate of the fifth wall 150 in the folded state.
