When the stick 400 is inserted into the insertion space 214, the end of the stick 400 may contact the second guide 306. When the end of the stick 400 contacts the second guide 306, the second guide 306 may guide the stick 400 to the correct position in the insertion space 214.

The first guide 216 may be disposed in a position opposite to the second guide 306. The first guide 216 may be disposed lower than the second guide 216.

When the stick 400 is inserted into the insertion space 214, the end of the stick 400 may contact the first guide 216. The end of the stick 400 may first contact the second guide 306 to guide its position and then contact the first guide 216. When the end of the stick 400 contacts the first guide 216, the first guide 216 may guide the stick 400 to the correct position in the insertion space 214.

When inserted into the insertion space 214, the end of the stick 400 may contact the stick stopper 217. The stick stopper 217 may contact the end of the stick 400 to restrict the stick 400 from moving to the lower side of the insertion space 214 or the second chamber C2.

Accordingly, when the user pushes the cover 310 through the stick 400, the position of the stick 400 is guided to an accurate position so that it can smoothly pass through the insertion hole 304, so that the cover 310 can be pushed out.

In addition, even if the stick 400 pushes the cover 310 and the cover 310 is placed inside the insertion space 214, the cover 310 is received in the cover groove 215, so that the stick 400 is inserted. It may be in close contact with the wall dividing the space 214.

In addition, since the stick 400 is in close contact with the wall dividing the insertion space 214, when the user inhales air through the stick 400, air is unnecessarily drawn between the insertion space 214 and the stick 400. It is possible to prevent the air flow efficiency from being reduced by preventing it from flowing and reducing wasted suction power.

In addition, even when the user pushes the cover 310 through the stick 400 and the cover 310 applies an external force to the end of the stick 400 in the second direction, the stick 400 remains in the insertion space 214. It can be guided to be inserted correctly.

Additionally, movement of the stick 400 inside the second chamber C2 may be restricted.
