Description

CROSS REFERENCE TO RELATED APPLICATION

The present application claims priority to Korean Patent Application No. 10-2021-0176212, filed Dec. 10, 2021, the entire contents of which is incorporated herein for all purposes by this reference.

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a mist sprayer, which sprays cosmetics in the form of a spray and, more particularly, to a container housing of the mist sprayer with an improved structure to prevent the outflow of stored cosmetics.

Description of the Related Art

Conventional mist sprayers have been introduced in Korean Patent Publication No. 10-2018-0051873, Korean Patent Publication No. 10-2018-0097067, Korean Patent Registration No. 10-2152955 and etc. and are gradually widely used due to their advantage of being able to be used without a problem of nozzle clogging even when spraying a cosmetic fluid having a high viscosity.
However, depending on the type of cosmetic solution, the nozzle may still be blocked by the cosmetic solution solidified by the suspended particles contained in the aqueous solution. As, in this case, the mist sprayer cannot be used as a whole and had to be disposed of according to the above-described conventional technologies, a solution to this problem was required.
In order to solve such a conventional problem, the applicant proposed a mist sprayer 1 as shown in FIG. 1 . It has an improved structure that allows a nozzle 350 to be installed in a container housing 300 detachably coupled to a main body housing 100. In the event of a failure in which the nozzle 350 is blocked, the container housing 300 may be replaced with a new one like consumables to be mounted on the main body housing 100. Therefore, it is possible to solve the problem of disposing of the entire mist sprayer 1.
With this improvement, as shown in FIGS. 1 and 2 , a vent hole 332 is formed in a sealing lid 330 to help the cosmetic liquid stored in a storage tank 320 to flow smoothly into a cosmetic liquid outflow pipe 322.
However, since the mist sprayer 1 is frequently carried by the user in a bag or the like, it may be possible to respond to some extent by setting the size of the vent hole 332 slightly smaller in consideration of cases where it is stored sideways or upside down.
However, in the case of an external impact, the outflow occurred through the vent hole 332, so a corresponding improvement was required.

SUMMARY OF THE INVENTION

Accordingly, the present disclosure has been made keeping in mind the above problems occurring in the related art, and the objective of the present disclosure is to provide an improved container housing for a mist sprayer to prevent the cosmetic liquid stored in the storage tank from leaking through the vent hole.
In order to achieve the above objective, the present disclosure provides a container housing for a mist sprayer, the container housing comprising a storage tank formed in an inner space of a container wall to store cosmetic liquid, a cosmetic liquid outlet formed in the center of a depressed surface that forms a bottom of the storage tank, a sealing lid coupled to an upper end of the container wall to cover the open upper end of the storage tank so as to be opened and closed, wherein the sealing lid comprises a cap receiving part formed by depression from the surface of a cover plate, a leak storage space part formed by being depressed into a narrower inner diameter with a step as a boundary with the cap receiving part, and a microtube formed to protrude toward the depressed surface of the storage tank by being depressed from the bottom surface of the leakage storage space, the container housing further comprising a sealing cap inserted into the cap receiving part and tightly coupled therein, the sealing cap having a fine vent pipe communicating between the outside of the cover plate and the leakage storage space part.
According to an aspect of the present disclosure, a protruding end of the microtube is located higher than the level of the cosmetic liquid of a standard capacity of the storage tank whether the container housing is in an upright state or in an inverted state, and the microtube is always located higher than the level of the cosmetic liquid of the standard capacity until the container housing in the upright state is tilted to a horizontal lying state.
According to an aspect of the present disclosure, the sealing lid has a lid wall formed to a certain depth along the edge, the protruding end of the microtube is formed to extend substantially to a lower end of the lid wall, and the level of the cosmetic liquid of the standard capacity is lower than the lid wall when the container housing is in the inverted state.
According to an aspect of the present disclosure, the cosmetic liquid of the standard capacity is accommodated only in the storage tank and does not contact the lid wall when the container housing is in the upright state.
According to an aspect of the present disclosure, the sealing cap is made of silicon.
According to the container housing for a mist sprayer according to the present invention as described above, although external air may flow into the inner space of the storage tank through the fine vent pipe of the of the sealing cap, the leakage storage space part and the microtube, the cosmetic liquid stored in the storage tank can be made to be difficult to flow out through the microtube. Even if there is a cosmetic liquid that passes through the microtube, it will only smear on the bottom of the leakage storage space part so that it is very difficult to flow out through the fine vent pipe of the sealing cap. Therefore, it is possible to substantially prevent the cosmetic liquid stored in the storage tank from leaking to the outside.

DETAILED DESCRIPTION OF THE INVENTION

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.
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 435 a of the leakage storage space part 435.
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 436 a forming the lower end of the microtube 436 is extended to approximately coincide with the lower end line of the lid wall 437.
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.
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.
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 436 a 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.
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 436 a 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.
FIG. 8 shows the container housing 400 in a horizontal lying state. Even at this state, the protruding end 436 a of the microtube 436 is still positioned higher than the water level M3 of the cosmetic liquid L accommodated to the standard capacity.
According to these principles, it can be seen that the protruding end 436 a 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 .
In addition, even in the inverted state of FIG. 7 , since the cosmetic liquid L does not reach the protruding end 436 a of the microtube 436, it can be seen that the outflow through the microtube 436 will be extremely rare.
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 435 a of the leakage storage space part 435 connected at a right angle from the microtube 436, so it does not immediately leak outside.
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 435 a which is perpendicular to the microtubule 436, an inner wall surface 435 b which is perpendicular to the bottom surface 435 a and reach the sealing cap 440 which is perpendicular to the inner wall surface 435 b.
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.
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.
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.
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.
