[0133] When the cover 310 pivots in the first direction to open the insertion space 214, the cover 310 may be accommodated in the cover groove 215. When the cover 310 opens the insertion space 214, the cover 310 may be accommodated in the cover groove 215 and may overlap the inner wall 212 of the first container 210 located below the cover groove 215. When the cover 310 opens the insertion space 214, the cover 310 may be arranged parallel to the inner wall 212 of the first container 210 located below the cover groove 215.

[0134] The first guide 216 may be formed to be inclined from the bottom of the cover groove 215 toward the lower side of the insertion space 214. The first guide 216 may be formed to be inclined so that the insertion space 214 becomes gradually narrower as it goes downward. When the cover 310 opens the insertion space 214, the first guide 216 may be disposed adjacent to one end of the cover 310 on the lower side of the cover 310. When the cover 310 opens the insertion space 214, the first guide 216 may protrude into the insertion space 214 beyond the end of the cover 310.

[0135] The cover 310 may pivot toward the outside of the insertion space 214 to close the insertion space 214 and / or the insertion opening 304. The direction in which the cover 310 pivots toward the outside of the insertion space 214 may be defined as a second direction. One end of the spring 312 may support the cover 310, and the other end of the spring 312 may support the cap 300. The spring 312 may provide an elastic force to the cover 310 in a direction in which the cover 310 closes the insertion space 214. The cover 310 may pivot in the second direction via the spring 312.

[0136] The second guide 306 may be formed at an angle such that the inner space gradually narrows toward the bottom. The second guide 306 may be disposed adjacent to the pivot radius of the cover 310. The second guide 306 may be disposed outside the pivot radius of the cover 310. The second guide 306 may extend at an angle along the pivot radius of the cover 310.

[0137] One end of the second guide 306 may be located adjacent to the insertion opening 304. One end of the second guide 306 may be located outside the insertion opening 304. One end of the second guide 306 may be located below the insertion opening wall 305. The insertion opening wall 305 may protrude inward beyond one end of the second guide 306. When the cover 310 pivots in the second direction to close the insertion space 214, the cover 310 comes into contact with the insertion opening wall 305, thereby restricting the movement of the cover 310.

[0138] The other end of the second guide 306 may be located adjacent to the insertion space 214. The other end of the second guide 306 may be located adjacent to the outer wall 211 of the first container 210 that defines the periphery of the insertion space 214. The other end of the second guide 306 may be disposed above the outer wall 211 of the first container 210 that defines the insertion space 214. The second guide 306 may have a shape that extends obliquely from one end to the other end of the second guide 306.

[0139] 19 to 22, the stick 400 can push the cover 310 inward or in a first direction into the insertion space 214. 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.

[0140] 19 and 20 , when the end of the stick 400 passes through the insertion opening 304, the end of the stick 400 can come into contact with the insertion opening wall 305. When the end of the stick 400 comes into contact with 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 out the cover 310, causing the cover 310 to pivot in a first direction.

[0141] 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 overlaps the inner wall 212 of the first container 210 and can form one side wall of the insertion space 214 together with the inner wall 212 of the first container 210.

[0142] 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 around 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 come into contact with the second guide 306. When the end of the stick 400 comes into contact with the second guide 306, the second guide 306 can guide the stick 400 to a fixed position within the insertion space 214.

[0143] The first guide 216 may be positioned opposite the second guide 306. The first guide 216 may be positioned lower than the second guide 216. The first guide 216 may be positioned below the cover groove 215. The first guide 216 may be positioned below the cover 310. The first guide 216 may extend circumferentially 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 into position, and then contact the first guide 216. When the end of the stick 400 contacts the first guide 216, the first guide 216 can guide the stick 400 to a fixed position within the insertion space 214.

[0144] 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.

[0145] Therefore, when a 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 a precise position so as to push out the cover 310.

[0146] Furthermore, 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, allowing the stick 400 to adhere closely to the wall that defines the insertion space 214.

[0147] In addition, since the stick 400 is in close contact with the wall that defines 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, thereby reducing wasted suction force and preventing a decrease in the efficiency of air flow.

[0148] 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.

[0149] In addition, the stick 400 can be restricted from moving inside the second chamber C2.
