Description

[0002] AEROSOL CAN HAVING LOCKING STRUCTURE [0003]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distributor for spraying contents using internal pressure.

Generally, a dispenser refers to a container that allows the contents to be discharged to the outside by using the internal pressure while the contents (fluid or gas) to be injected are sealed inside the housing. Typical examples of such dispensers are portable gas containers, spray mosquito repellents, hair sprays, portable aerosol fire extinguishers, and gas lighter containers.

These dispersing apparatuses spray aerosol particles, and spray type sunscreen powder dispensers for spraying ultraviolet rays with skin protection cream (sun cream) and spraying them on the user's skin have been commercialized.

However, such a spray type has a problem that the particles of the aerosol must be sprayed toward the face. In addition, the spray type has a problem that particles are scattered around when sprayed.

Accordingly, the present invention proposes a dispenser that operates in a new coating system rather than spraying the contents.

It is an object of the present invention to provide a new type of dispenser capable of applying contents to a human body.

Another object of the present invention is to provide a locking structure in which the brush is moved while the dispenser is not used to prevent the contents from flowing and contaminating the surrounding objects.

In an exemplary embodiment, the housing and the brush module may be coupled to each other.

In an embodiment, the intermediate member may include a body for accommodating at least a part of the housing, and an inner rim protruding from the inner circumference of the body toward the central axis of the intermediate member.

In one embodiment of the present invention, the brush housing is formed to be rotatable with respect to the central axis of the intermediate member, and at least one of the intermediate member and the brush housing is provided with the brush housing, A locking part for locking or unlocking the moving part can be formed.

The locking portion may be formed on one of the intermediate member and the brush housing and the other one of the intermediate member and the brush housing. The rotation of the brush housing may sequentially move the projection And may include opposing projections and counter grooves.

In an embodiment, the projection may include: a first projection formed to prevent the brush housing from being tilted right and left with respect to the central axis of the intermediate member; And a second projection formed in a direction intersecting with the first projection to prevent the brush housing from sliding relative to the central axis of the intermediate member.

In an embodiment, the mating protrusion may be formed with an insertion groove into which the first protrusion is inserted in the locked state.

In an embodiment, the mating groove is formed to be widened downward so that the brush housing can be tilted with respect to the central axis of the intermediate member in a state where the projection is accommodated in the mating groove in the unlocking state .

In an embodiment, the intermediate member may further include a latching protrusion protruding in a direction intersecting with the inner rim and hooked to at least a part of the mount cup.

In an exemplary embodiment, the mount cup may have a seaming engagement portion seamed to the housing, and the seaming engagement portion may be seated in a space defined by the inner ledge and the engagement portion.

In an embodiment, the brush housing may include a receiving groove portion in which at least a part of the brush is received, and a flow path portion in which a flow path from the receiving groove portion to the valve stem is formed.

In an embodiment, the flow path portion may include an insertion portion into which the discharge port of the valve stem is inserted, and a protrusion protruding from the insertion portion to be disposed inside the brush.

In an embodiment, the diameter of the second flow path formed in the protrusion may be smaller than the diameter of the first flow path formed in the insertion portion.

In an embodiment, the valve stem is mounted to the stem housing so as to be capable of sliding and tilting, and the brush housing is formed so as to apply an external force to the valve stem to cause the sliding movement and the tilting of the valve stem .

According to the present invention, as the aerosol sprayed from the distributor is introduced into the brush, the spray application method of the distributor can be changed to the brush application method. In addition, it is possible to implement a dispenser capable of dispensing the contents through a brush without spraying the contents directly onto the human body. Furthermore, a dispenser is implemented in which the user applies sunscreen more safely to the face, and is restricted from scattering around.

Also, in the locked state in which the brush housing is fixed to the housing of the dispenser, the brush housing may be slid or not tilted when an external force is applied to the brush when the dispenser is not used. Thus, it is possible to mitigate or prevent contamination of articles and the like due to the contents flowing out while the dispenser is being stored or moved.

In the present specification, the same reference numerals are given to the same components in different embodiments, and the description thereof is replaced with the first explanation. As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.

FIG. 1 is a longitudinal sectional view of a distributor having a locking structure according to an embodiment of the present invention, and FIG. 2 is an enlarged cross-sectional view of the valve assembly of FIG.

Referring to this figure, the dispenser 100 includes a housing 110 and a valve assembly 200.

The housing 110 is formed so as to have an accommodation space S in which contents and injection gas are accommodated. The contents may be, for example, fluid or gas. More specifically, the contents may be a sun cream and a gas.

The housing 110 may include a body 111 having an accommodation space S and a lower sealing cap 112 for sealing both ends of the body 111. The lower sealing cap 112 may have a curved shape toward the accommodation space S so as to be deformable to enlarge the volume of the accommodation space S when a certain level of overpressure is applied to the accommodation space S .

The container body 111 may contain high pressure gas or liquid contents, and may be formed in the form of a metal can that can withstand a constant internal pressure.

In the illustrated embodiment, a mount cup 120 for supporting the valve assembly 200 is coupled to the upper end of the housing 110. The housing 110 can be joined to the mount cup 120 by seaming, and thus the mount cup 121 is formed in the mount cup. The shim coupling part 121 may be formed along the edge of the mount cup 120, and may be a part seamed to the housing 110. The seaming joining part 121 may be coupled to the housing 110 by double or triple seaming. However, the present invention is not limited thereto, and the seaming part 121 may be formed by a single seaming.

A protruding portion 122 is provided at the center of the mount cup 120 to fix the valve assembly 200.

The valve assembly 200 is installed in the mount cup 120 with one end disposed in the accommodation space S and the other end exposed to the outside of the housing 110, The contents are sprayed to the outside.

More specifically, a through hole is formed in a central portion of the upper end of the protruding portion 122 of the mount cup 120, and a part of the valve stem 210 constituting the valve assembly 200 is passed through the through- It is exposed. The valve stem 210 is provided so as to be pressed in the vertical direction, and when the contents of the accommodation space S is sprayed by the depression thereof and the depression is released, the injection of the contents is stopped. In addition, the valve stem may be provided so as to be tilted in the left-right direction and may be formed so that the contents of the accommodation space S are tilted by the tilting and the injection of the contents is stopped when the tilting is released.

Referring to FIG. 2, a locking protrusion 123 protrudes from the inner surface of the protruding portion 122. The engaging protrusion 123 may be formed by a reduction in section through clamping or the like to the outer surface of the mount cup 120. [

The stem housing (220) is fixed to the locking protrusion (123). At least part of the stem housing (220) is hooked on the locking protrusion (123).

For example, the stem housing 220 has a peripheral protrusion 221 formed on the outer circumferential surface of the stem housing 220. The protrusion portion 122 of the protruding portion 122 is engaged with the peripheral protrusion 221, And is fixed to the protruding portion 122 of the cup 120.

A hollow portion 222 communicating with the accommodation space S of the housing 110 is formed in the stem housing 220 and the valve stem 210 is disposed to be able to slide and tilt in the hollow portion 222 .

Hereinafter, the operation of the valve assembly 200 will be described in more detail with reference to FIGS. 3A and 3B. FIGS. 3A and 3B are vertical cross-sectional views illustrating states in which contents are injected in the container of FIG. 1;

The valve stem 210 is formed with an orifice 211 selectively communicating with the hollow portion 222 by sliding the valve stem 210 (see FIG. 3A) or by tilting the valve stem (see FIG. 3B) do.

The stem housing 220 is provided with an opening / closing member 231 that is elastically deformed to open and close the orifice 211 in conjunction with sliding and tilting of the valve stem 210.

When the valve stem 210 is slid by the external force F, the opening and closing member 231 is bent and elastically deformed and the passage between the hollow portion 222 of the stem housing 220 and the valve stem 210 is communicated with each other, . On the contrary, when the force pressing the valve stem 210 is removed, the valve stem 210 is restored and deformed by the elastic force of the spring 232 supporting the lower end of the valve stem 210. As a result, the opening / closing member 231 closes the orifice 211 by being in close contact with the valve stem 210, and the outflow of the gas is blocked.

In this case, the lower end of the valve stem 210 and the spring 232 are spaced apart from the side wall of the hollow portion by a specific distance so as to be relatively movable left and right in the hollow portion. That is, it is not fixed to the portion where the spring 232 is seated, so that the valve stem can be tilted. When the valve stem 210 is tilted by the external force F, the opening and closing member 231 is elastically deformed while being bent and the contents are sprayed. When the external force is removed, the valve stem 210 is restored and deformed by the elastic force of the spring 232.

Through such a mechanism, a valve stem that is opened and closed by sliding movement and left and right tilting can be realized to selectively inject the contents.

Meanwhile, the distributor 100 shown in FIG. 1 has a mechanism for applying the contents using a brush, which will be described in detail with reference to FIGS. 4, 5, 6, and 7. FIG.

FIG. 4 is a perspective view of a distributor having a locking structure of FIG. 1 for explaining a brush module according to the present invention, FIG. 5 is an exploded perspective view of a distributor having a locking structure of FIG. 1, 4 is an enlarged sectional view showing a state in which the valve assembly and the brush module are unlocked, and FIG. 7 is an enlarged sectional view showing a state in which the valve assembly and the brush module of FIG. 4 are locked.

Referring to FIGS. 1 and 2, the distributor 100 includes a brush module 300 so that the sprayed aerosol particles can be introduced and applied to the outside.

The brush module 300 is slidingly or tilted together with the valve stem, and includes a flow path through which the contents injected from the valve stem flows, and the contents discharged from the flow path are buried in the brush. More specifically, the brush module 300 includes a brush 310 and a brush housing 320.

The brush 310 is attached to the brush housing 320 so that the introduced contents can be buried. For example, the brush 310 is a form in which a plurality of artificial hairs are bundled, so that the contents in the dispenser leaks through the brushes and can be directly applied to the hand or face of the human body. However, the present invention is not limited thereto, and the artificial hair may be replaced with a sponge or the like.

The brush housing 320 includes a receiving groove 321 in which at least a portion of the brush 310 is received and a flow passage 322 in which a flow path from the receiving groove 321 to the valve stem is formed, .

More specifically, the flow path portion 322 includes an insertion portion 323 into which the discharge port of the valve stem is inserted and a protrusion 324 protruding from the insertion portion 323 to be disposed inside the brush 310 .

The protrusion 324 may protrude to the inner middle of the brush housing 320 and may be inserted into the brush 310 so that the contents can be easily applied at the bottom of the receiving groove 321. Thus, as the protrusion 324 protrudes to the inner center of the brush housing 320, the contents can be easily guided to the brush 310 by the spraying force of the aerosol gas.

In this case, the diameter of the second flow path 324a formed in the protrusion 324 may be smaller than the diameter of the first flow path 323a formed in the insertion portion 323.

The insertion portion 323 is recessed from the lower end surface of the brush housing 320 toward the receiving groove 321 and an outlet of the valve stem 210 is inserted to communicate with the valve stem 210. Therefore, the diameter of the first flow path 323a may be greater than or equal to the outer diameter of the discharge port of the valve stem 210.

The brush housing 320 is configured to receive the brush and is movable with respect to the housing 110 to apply the external force to the valve stem 210.

That is, the brush housing 320 is formed to apply an external force to the valve stem 210 by the user's manipulation to generate the sliding movement and the tilting.

For example, when the brush housing 320 is tilted, the contents are ejected by tilting as described above with reference to FIG. 3B. Therefore, when the brush is applied to the application site and the dispenser is used, the contents may come out.

To this end, the housing 110 and the brush module 300 may be coupled to the intermediate member 400, respectively.

The intermediate member 400 includes a body 410 into which at least a part of the housing 110 is inserted and an inner jaw 420 protruding from the inner circumference of the body 410 toward the center axis of the intermediate member 400. [ ).

The body 410 is formed in the body 410 so as to fit into the body 111 of the housing so that the lower end of the body 111 of the body is exposed to the outside. The length is made shorter. Through this, the housing can be easily replaced by using the lower end of the body 111 of the housing.

The intermediate member 400 may include a latching portion 411 protruding in a direction intersecting with the inner rim 420 and hooked on at least a part of the mount cup 120.

More specifically, the seaming engagement portion 121 may be seated in a space defined by the inner rim 420 and the engagement portion 411. The inner jaw 420 and the engaging portion 411 are disposed so as to be substantially orthogonal to each other at the inner side of the intermediate member 400 and close to the point where the inner jaw 420 and the engaging portion 411 meet A space in which the seaming joining part 121 can be seated can be formed.

The brush housing 320 according to the present invention includes an unlocking state in which the valve stem 210 can move relative to the housing 110 and an unlocking state in which the valve stem 210 is fixed to the housing 110, As shown in FIG.

At least one of the intermediate member 400 and the brush housing 320 may be configured such that the brush housing 320 is moved with respect to the intermediate member 400 by the rotation of the brush housing 320 A locking part for locking or unlocking can be formed.

The locking part includes a protrusion 430 formed on one of the intermediate member 400 and the brush housing 320 and a protrusion 430 formed on another one of the intermediate member 400 and the brush housing 320. [ 325, and mating grooves 326, as shown in FIG.

Meanwhile, the brush housing 320 may be rotatable about the center axis of the intermediate member 400. By this rotation, the projection 430 can be arranged to face the mating projection 325, or to face the mating groove 326. In other words, the mating protrusion 325 and the mating grooves 326 can sequentially face the protrusion 430 by the rotation of the brush housing 320.

For example, the intermediate member 400 may be provided with protrusions 430 spaced apart from each other at a specific distance in the circumferential direction.

The mating protrusion 325 and the mating recesses 326 may be disposed in the brush housing 320 and may be arranged in the circumferential direction.

More specifically, the counter protrusion 325, the mating groove 326, and the stopper 327 may be alternately arranged in the brush housing 320. The number of the mating protrusions 235, the mating grooves 326, and the stoppers 327 may be the same as the number of the protrusions 430.

The movement of the brush housing 320 is limited in a state in which the protrusion 430 is opposed to the mating protrusion 325 provided in the brush housing 320 and thus can be locked. In contrast, when the protrusion 430 faces the mating grooves 326, the brush housing 320 can move and thus can be unlocked.

The protrusion 430 may include a first protrusion 432 formed in a direction substantially parallel to the central axis to prevent the brush housing 320 from being tilted right and left with respect to the center axis of the intermediate member 400, And a second protrusion 433 formed in a direction intersecting the first protrusion 432 to prevent the brush housing 320 from sliding with respect to the center axis.

The first and second protrusions 432 and 433 may be formed on the protrusion body 431, respectively. The protrusion body 431 may include a curved surface corresponding to the circumferential shape of the intermediate member 400. In other words, the surface of the protrusion body 431 facing the center axis of the intermediate member 400 may be curved.

Further, at least a part of the side surface of the projection body 431 may be curved. At this time, at least a part of the side surface of the mating groove 326 may have a curved surface shape corresponding to the curved surface of the projection body 431.

In the state where the protrusion 430 is accommodated in the mating groove 326 in the unlocked state, the mating groove 326 is tilted right and left with respect to the central axis of the intermediate member 400, So that it becomes wider as it goes downward.

In other words, when the brush housing 320 is tilted to the left and right, the protrusions 430 may be biased toward the left side in the mating groove 326, or may be biased to the right side.

On the other hand, as described above, in the locked state, the protrusions 430 may be arranged to face the mating protrusions 325. [

More specifically, the mating protrusion 325 may be formed with an insertion groove 325a for inserting the first protrusion 432 in the locked state. That is, the insertion groove 325a may be formed on the mating protrusion 325 along a direction parallel to the center axis of the brush housing 320. [ When the first protrusion 432 is inserted into the insertion groove 325a, the brush housing 320 can be prevented from being tilted with respect to the intermediate member 400.

Meanwhile, the stopper 327 may be formed thicker than the mating protrusion 325 to limit the range of rotation of the brush housing 320. That is, the brush housing 320 can be rotated in a direction in which the protrusion 430 faces the mating groove 326 in a state where the first protrusion 432 is inserted into the insertion groove 325a However, the protrusion 430 can not be rotated in the direction opposite to the stopper 327.

The second projection 433 contacts the lower surface of the mating protrusion 325 in the locked state to prevent the brush housing 320 from slidably moving with respect to the central axis of the intermediate member 400 .

Since the dispenser of the present invention is a touch brush type, when the brush is tilted directly to the application region, the contents are released, so that the content can easily flow out during storage or movement to contaminate nearby objects. . For this purpose, the dispenser may further comprise an outer cap 500 (see FIG. 1) for receiving the brush housing.

The distributor and its valve assembly as described above are not limited to the construction and operation of the embodiments described above. The embodiments may be configured so that all or some of the embodiments may be selectively combined so that various modifications may be made.
