Referring to fig. 19 to 22, the rod 400 may push the cover 310 in an inward direction of the insertion space 214 or in a first direction. When the rod 400 pushes the cover 310 and inserts into the insertion space 214, the cover 310 may open the insertion space 214 and/or the insertion hole 304.

Referring to fig. 19 and 20, when the end of the rod 400 passes through the insertion hole 304, the end of the rod 400 may contact the insertion hole wall 305. When the end of the rod 400 contacts the insertion hole wall 305, the insertion hole wall 305 may guide the rod 400 to the correct position in the insertion hole 304. After passing through the insertion hole 304, the end of the rod 400 may push the cover 310 such that the cover 310 pivots in the first direction.

Referring to fig. 20 and 21, when the rod 400 completely passes through the insertion hole 304, the cover 310 may be received in the cover recess 215. The cover 310 may overlap the inner wall 212 of the first container 210, thereby forming one sidewall of the insertion space 214 together with the inner wall 212 of the first container 210.

Referring to fig. 21 and 22, the rod 400 may slide along the surface of the cover 310 and may be inserted into the insertion space 214. The second guide 306 may be disposed at a position opposite to the pivot shaft of the cover 310 with respect to the insertion hole 304. The second guide 306 may be disposed at a position opposite to the cover recess 215. When the rod 400 is inserted into the insertion space 214, an end of the rod 400 may contact the second guide 306. When the end of the rod 400 is in contact with the second guide 306, the second guide 306 may guide the rod 400 to the correct position in the insertion space 214.

The first guide 216 may be disposed at a position opposite the second guide 306. The first guide 216 may be disposed below the second guide 306. The first guide 216 may be disposed under the cover recess 215. The first guide 216 may be disposed under 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 rod 400 is inserted into the insertion space 214, an end of the rod 400 may contact the first guide 216. After being guided to the correct position by contact with the second guide 306, the end of the rod 400 may be in contact with the first guide 216. When the end of the rod 400 contacts the first guide 216, the first guide 216 may guide the rod 400 to a correct position in the insertion space 214.

The end of the rod 400 inserted into the insertion space 214 may be in contact with the rod stopper 217. The rod stopper 217 with which the end of the rod 400 contacts may prevent the rod 400 from moving to a region below the insertion space 214 or to the second chamber C2.

Thus, when the user pushes the cover 310 using the stick 400, the stick 400 may be guided to a correct position so as to smoothly pass through the insertion hole 304 and push the cover 310.

Further, when the rod 400 pushes the cover 310 and thus the cover 310 is disposed in the insertion space 214, the cover 310 is received in the cover recess 215, and thus the rod 400 may be in close contact with the wall defining the insertion space 214.

Further, since the stick 400 is in close contact with the wall defining the insertion space 214, when a user inhales air through the stick 400, it is possible to prevent unnecessary flow of air between the insertion space 214 and the stick 400 and reduce waste of the suction force, thereby preventing deterioration of air flow efficiency.

Further, even when the user pushes the cover 310 using the stick 400, the cover 310 applies an external force to the end of the stick 400 in the second direction, the stick 400 can be guided so as to be correctly inserted into the insertion space 214.

In addition, the rod 400 may be prevented from moving to the inside of the second chamber C2.
