When the stick 400 is inserted into the insertion space 214 while pushing out the cover 310, the cover 310 can open the insertion space 214 and/or the insertion opening 304.

Referring to FIG. 19 and FIG. 20, when the end of the stick 400 passes through the insertion opening 304, the end of the stick 400 can contact the insertion opening wall 305. When the end of the stick 400 contacts the insertion opening wall 305, the insertion opening wall 305 can guide the stick 400 to a fixed position within the insertion opening 304. When the stick 400 passes through the insertion opening 304, the end of the stick 400 can push the cover 310 to pivot the cover 310 in a first direction.

Referring to Figures 20 and 21, when the stick 400 passes through the insertion opening 304, the cover 310 can be inserted into the cover groove 215. The cover 310 can overlap the inner wall 212 of the first container 210 and form one side wall of the insertion space 214 together with the inner wall 212 of the first container 210.

21 and 22, the stick 400 can be inserted into the insertion space 214 by sliding along the surface of the cover 310. The second guide 306 can be disposed at a position facing the pivot axis of the cover 310, centered on the insertion opening 304. The second guide 306 can be disposed at a position facing the cover groove 215. When the stick 400 is inserted into the insertion space 214, the end of the stick 400 can contact the second guide 306. When the end of the stick 400 contacts the second guide 306, the second guide 306 can guide the stick 400 to a fixed position within 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 below the second guide 216. The first guide 216 may be disposed below the cover groove 215. The first guide 216 may be disposed below the cover 310. The first guide 216 may extend in a circumferential direction along the inner wall 212 of the first container 210. 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 be guided to a 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 a fixed position in the insertion space 214.

When inserted into the insertion space 214, the end of the stick 400 can come into contact with the stick stopper 217. By coming into contact with the end of the stick 400, the stick stopper 217 can restrict the stick 400 from moving downward in the insertion space 214 or into the second chamber C2.

Therefore, when the user pushes out the cover 310 using the stick 400, the stick 400 can smoothly pass through the insertion opening 304 and be guided to the correct position to push out the cover 310.

In addition, even if the stick 400 pushes out the cover 310 and the cover 310 is positioned inside the insertion space 214, the cover 310 is accommodated in the cover groove 215, so that the stick 400 can be in close contact with the wall that defines the insertion space 214.

In addition, by fitting the stick 400 closely to the wall that divides the insertion space 214, unnecessary air flow between the insertion space 214 and the stick 400 is prevented when the user inhales air through the stick 400, reducing wasted suction force and preventing a decrease in the efficiency of air flow.

In addition, when the user pushes out the cover 310 through the stick 400, the cover 310 can guide the stick 400 so that it is accurately inserted into the insertion space 214 even if an external force is applied to the end of the stick 400 in the second direction.

In addition, the stick 400 can be restricted from moving inside the second chamber C2.
