DETAILED DESCRIPTION OF THE INVENTION

[0022] As shown in FIGS. 3 and 4, a container housing 400 according to the embodiment of the present invention includes a sealing cap 430. A cover plate 433 of the sealing lid 430 is recessed at the center of its surface to form a cap receiving part 432. A silicone sealing cap 440 is inserted into the cap receiving part 432 and is closely coupled to each other. A fine vent pipe 441 is vertically formed in the center of the sealing cap 440.

[0023] A leakage storage space part 435 is provided at a lower end of the cap receiving part 432 to be formed by being depressed into a narrower inner diameter with a stepped part 434 as a boundary (see FIG. 5). A microtube 436 is further provided to be formed by being depressed from a horizontal bottom surface 435a of the leakage storage space part 435.

[0024] Referring to FIG. 5, a lid wall 437 forming the edge of the sealing lid 430 is formed to have a predetermined height up and down, that is, a predetermined depth (H) unlike the conventional technology (see 330 in FIG. 2). A protruding end 436a forming the lower end of the microtube 436 is extended to approximately coincide with the lower end line of the lid wall 437.

[0025] FIG. 6 illustrates a state in which the sealing lid 430 as described above is coupled to a storage tank 420. The storage tank 420 in which the cosmetic liquid is accommodated is defined by a container wall 410 as an inner space thereof. A cosmetic liquid outlet (not shown in the drawing, see 322 of FIG. 2) is formed at the center of a recessed surface 421 forming an inclined bottom of the storage tank 420.

[0026] The sealing lid 430 is coupled to the upper end of the container wall 410 to cover the open upper end of the storage tank 420 so as to be opened and closed.

[0027] FIG. 6 shows the container housing 400 in an upright state where the cosmetic liquid L is accommodated in the storage tank 420 to its standard capacity (ex. 7 cc). The volume of the storage tank 420 is set so that the cosmetic liquid L is sufficiently contained by forming its level M1 up to about half the height of the container wall 410. Accordingly, the protruding end 436a of the microtube 436 of the sealing lid 430 is positioned higher than the level M1 of the cosmetic liquid L, so that it does not allow the cosmetic liquid L to contact or permeate therein.

[0028] FIG. 7 shows the container housing 400 in an inverted state where the cosmetic liquid L accommodated to the standard capacity is contained only in the sealing lid 430. That is, the water level M2 of the cosmetic liquid L forms a lower height than the lid wall 437. In this case, as the protruding end 436a of the microtube 436 is substantially on the same height line as the lid wall 437, it is still located higher than the level M2 of the cosmetic liquid L. Therefore, it is possible to prevent the cosmetic liquid L from easily permeating.

[0029] FIG. 8 shows the container housing 400 in a horizontal lying state. Even at this state, the protruding end 436a of the microtube 436 is still positioned higher than the water level M3 of the cosmetic liquid L accommodated to the standard capacity.

[0030] According to these principles, it can be seen that the protruding end 436a of the microtube 436 is always located higher than the level (see M1, M3) of the cosmetic liquid L from the standing state of FIG. 6 to the horizontal lying state of FIG. 8.

[0031] In addition, even in the inverted state of FIG. 7, since the cosmetic liquid L does not reach the protruding end 436a of the microtube 436, it can be seen that the outflow through the microtube 436 will be extremely rare.

[0032] Moreover, even if the cosmetic liquid L in the state including any of FIGS. 6 to 8 flows into the microtube 436 due to the external impact or others, it is primarily deemed to be stained on the bottom surface 435a of the leakage storage space part 435 connected at a right angle from the microtube 436, so it does not immediately leak outside.

[0033] Since the cosmetic liquid L flowing out to the leakage storage space part 435 will be only a small amount and this will mainly spread along the wall, it will be very difficult for the cosmetic liquid to pass through the bottom surface 435a which is perpendicular to the microtubule 436, an inner wall surface 435b which is perpendicular to the bottom surface 435a and reach the sealing cap 440 which is perpendicular to the inner wall surface 435b.

[0034] Finally, the cosmetic liquid L must pass through the fine vent pipe 441 located in the center of the sealing cap 440 again in order to be discharged to the outside.

[0035] Therefore, it is practically impossible for such a series of phenomena to occur in succession and the cosmetic liquid L to flow out of the container housing 400.

[0036] A cone-shaped protruding end part (442 in FIG. 4) protruding from the bottom surface of the sealing cap 440 can contribute to further complicating the outflow path of the cosmetic liquid L.

[0037] Meanwhile, the container housing 400 for a mist sprayer described above is only an embodiment for helping the understanding of the present disclosure, so the scope of the present disclosure defined by the claims to be described below should not be limited by the above description.
