Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a cosmetic brush assembly having a brush used for the make-up of a cosmetic powder on the one end thereof and more particularly, to a cosmetic brush assembly capable of coupling a cosmetic powder retaining tank on the other end thereof and injecting cosmetic powder in the cosmetic powder retaining tank to the brush by the action of air pumping, such that in use, the injection force of the cosmetic powder can be increased and an amount of cosmetic powder injected can be adjusted.

[0003] 2. Description of the Related Art

[0004] In order for a user to paint a cosmetic powder retained in a powder case on his or her face, generally, she first opens the cover of the powder case and then covers the brush mounted on a cosmetic brush assembly with the cosmetic powder exposed to the outside. After the completion of the make-up, however, she frequently fails to keep her powder case in a clean state due to the carelessness of the treatment.

[0005] Additionally, it is inconvenient to carry both the powder case and the cosmetic brush assembly, respectively.

[0006] In a conventional cosmetic brush assembly, typically, the brush and the cosmetic powder tank are simply connected to each other, such that when the cosmetic powder is injected to the brush, the air pressure is dispersed and is thus difficult to reach the terminating end of the brush. In addition, because of a simple configuration, an amount of the cosmetic powder injected cannot be appropriately adjusted. As a result, it has been found that the brush is not uniformly covered with the cosmetic powder. With the conventional cosmetic brush assembly, therefore, a user cannot achieve a desired painting.

SUMMARY OF THE INVENTION

[0007] It is, therefore, an object of the present invention to provide a cosmetic brush assembly capable of having a cosmetic powder retaining tank on the one end thereof, whereby a cosmetic powder in the cosmetic powder retaining tank is injected to a brush by air pumping.

[0008] It is another object of the present invention to provide a cosmetic brush assembly capable of adjusting an amount of cosmetic powder injected to a brush from the cosmetic powder retaining tank and injecting the cosmetic powder to the whole brush in a uniform level.

[0009] It is yet another object of the present invention to provide a cosmetic brush assembly capable of treating a cosmetic powder in an easy manner, thereby preventing the interior of a handbag from being stained with the cosmetic powder, while a powder case is kept in the handbag.

[0010] It is still another object of the present invention to provide a cosmetic brush assembly capable of having a beautiful appearance and exerting various kinds of functions.

[0011] To attain these and other objects of the present invention, there is provided a cosmetic powder assembly including: a brush mounting member having a brush mounted on the one end thereof; a cosmetic powder retaining tank disposed on the one end of the brush mounting member and retaining a cosmetic powder therein; an air pump part mounted on the lower end of the cosmetic powder retaining tank; an injection nozzle having a plurality of injecting holes embedded in the brush in order to guide the cosmetic powder in the cosmetic powder retaining tank injected by a pumping operation of the air pumping part to the brush and a powder entering end disposed toward the cosmetic powder retaining tank; and an adjusting part disposed between the brush mounting member and the cosmetic powder retaining tank to adjust an amount of the cosmetic powder injected from the cosmetic powder retaining tank to the brush via the injection nozzle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0025] Now, an explanation of the configuration of a cosmetic brush assembly according to the present invention will be hereinafter discussed with reference to the accompanying drawings.

[0026] FIG. 1 is a perspective view of a cosmetic brush assembly according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of FIG. 1, and FIG. 3 is a sectional view taken along the line A-A in FIG. 1. FIG. 4 is a sectional view illustrating the state where the opened end of the cosmetic powder retaining tank is in an opened state by the action of an injection nozzle, FIG. 5 is a sectional view illustrating the state where the cosmetic powder in the cosmetic powder retaining tank is injected by virtue of an injection nozzle by the operation of an air pumping part, FIG. 6 is a sectional view illustrating the state before the cosmetic brush assembly according to another embodiment of the present invention is coupled, and FIG. 7 is a sectional view illustrating the coupling state of the cosmetic brush assembly of FIG. 6.

[0027] Referring to the drawings, a cosmetic brush assembly 10 according to the present invention includes a brush mounting member 20 having a brush 22 on the top end thereof. The brush mounting member 20 is a substantially hollow cylinder and forms a screw or protrusion (or groove) on the bottom end thereof, into which an adjusting part 50 as will be hereinafter discussed for adjusting an amount of cosmetic powder injected is screw-coupled or fitted. Also, an injection nozzle 40, which functions to guide the cosmetic powder to the brush 22, is inserted into the hollow portion of the brush mounting member 20, an explanation of which will be below discussed.

[0028] The injection nozzle 40 serves to guide a flowing passage of the cosmetic powder supplied from a cosmetic powder retaining tank 30 and takes a substantial cylinder. The injection nozzle 40 has a closed top end on which a plurality of injection holes of predetermined sizes and an opened bottom end. Also, the closed top end of the injection nozzle 40 is placed on the interior of the brush 22, for directly injecting the cosmetic powder to the brush 22.

[0029] As mentioned above, the brush mounting member 20 is screw-coupled to the adjusting part 50 for adjusting an amount of cosmetic powder injected to the brush 22, on the bottom end thereof. Also, the adjusting part 50 is screw-coupled to the cosmetic powder retaining tank 30 as will be discussed below.

[0030] In other words, the adjusting part 50 includes a hollow housing 52 screw-coupled to the cosmetic powder retaining tank 30, a tubular body 54 inserted into the hollow housing 52 under the support of an elastic body to close the hollow portion of the hollow housing 52, and a pressure member 56 for applying a force to the tubular body 54 to open the hollow portion of the hollowing housing 52.

[0031] The pressure member 56 of the adjusting part 50 is composed of a substantially cylindrical member 56a racing between the brush mounting member 20 and the adjusting part 50 screw-coupled to each other and a horizontal member 56b screw-coupled on the inside of the cylindrical member 56a and horizontally moving in a length direction of the cosmetic brush assembly 10, particularly, in a length direction of the hollow portion of the brush mounting member 20, in accordance with the racing of the cylindrical member 56a.

[0032] At this time, the horizontal member 56b may be formed integrally with the opened bottom end of the injection nozzle 40. And, graduations for measuring an amount of racing of the cylindrical member 56a are arranged on the outside of the cylindrical member 56a. Thus, the amount of racing of the cylindrical member 56a can be checked by the eyes of a user, such that an amount of cosmetic powder injected from the cosmetic powder retaining tank 30 can be adjusted. However, it can be appreciated to those skilled in the art that means for measuring the amount of racing of the cylindrical member 56a is not limited to the graduations.

[0033] The cosmetic powder retaining tank 30 retains the cosmetic powder therein and is provided with an air pumping part 32 for injecting the cosmetic powder to the brush 22, on the bottom end thereof.

[0034] Therefore, the cosmetic powder in the cosmetic powder retaining tank 30 is uniformly injected via the injection nozzle 40 to the brush 22, as indicated by arrows in FIG. 5, by the air pressure flowing into the cosmetic powder retaining tank 30 by the air pumping of the air pumping part 32. Then, the user of the cosmetic brush assembly 10 can paint the cosmetic powder on his or her face in the same manner as a conventional practice.

[0035] Referring now to FIGS. 3 to 5, an explanation of an operation state of the cosmetic powder brush assembly 10 according to an embodiment of the present invention will be discussed.

[0036] Referring to FIG. 3, first, the hollow housing 52 of the adjusting part 50 is screw-coupled between the cosmetic powder retaining tank 30 having the air pumping part 32 on the bottom end thereof and the brush mounting member 20, and the injection nozzle 40 is inserted into the hollow portion of the brush mounting member 20.

[0037] The tubular body 54 is inserted into the hollow housing 52 of the adjusting part 50 and attaches flanges 54a and 54b of predetermined sizes on the both ends thereof. The flanges 54a and 54b function to prevent the tubular body 54 from being deviated from the hollow housing 52, thereby making it possible to move the tubular body 54 in a length direction thereof.

[0038] On the other hand, the tubular body 54 is provided with a plurality of substantially oval holes H in a length direction thereof on the side adjacent to the bottom end thereof. The tubular body 54 has an opened top end on which the cut conical flange 54b is attached. Therefore, the cosmetic powder in the cosmetic powder retaining tank 30 flows into the plurality of holes H on the side of the tubular body 54 and is thus injected through the opened top end of the tubular body 54, as indicated by arrows in FIG. 5.

[0039] Between the lower portion of the top end of the tubular body 54 and the upper portion of the inside hollow portion of the hollow housing 52 is provided an elastic body 58. By virtue of the elastic force of the elastic body 58 and the flange 54a of the lower portion of the tubular body 54, the tubular body 54 is kept completely exposed on the upper portion of the hollow housing 52. In this state, the holes H formed on the side of the tubular body 54 are kept completely closed by the inside of the hollow housing 52.

[0040] As discussed above, in the state where the holes H on the side of the tubular body 54 are closed, if the cylindrical member 56a of the pressure member 56 of the adjusting part 50 is raced, the horizontal member 56b screw-coupled to the inside of the cylindrical member 56a moves horizontally along the direction of an arrow as indicated in FIG. 4. In that case, as the horizontal member 56b moves in a length direction of the cosmetic brush assembly 10, the force in the arrow direction of FIG. 4 is applied to the tubular body 54 of the adjusting part 50, such that the tubular body 54, which is in contact with the horizontal member 56b, moves horizontally in the same direction as in FIG. 4.

[0041] As a result, the oval holes H formed on the side of the tubular body 54 are exposed to the outside of the hollow housing 52, namely, to the interior of the cosmetic powder retaining tank 30. In the state where the top end of the tubular body 54 of the adjusting part 50 has been in contact with the horizontal body 56b, the opened top end of the tubular body 54 and the opened end on the bottom end of the injection nozzle 40 are communicated with each other, thereby flowing air therein. At this time, between the top end of the tubular body 54 and the horizontal member 56b is provided a rubber packing material 53 for maintaining their connection in a tightly closed state.

[0042] Referring to FIG. 5, in the state where the oval holes H on the side of the tubular body have been exposed to the interior of the cosmetic powder retaining tank 30, if a pumping switch of the air pumping part 32 is pressed toward the arrow direction, air flows to the cosmetic powder retaining tank 30 through an air discharging hole of the discharging nozzle of the air pumping part 32. The air flowing into the cosmetic powder retaining tank 30 flows in the interior of the tubular body 54 via the oval holes H on the side of the tubular body 54 and is then discharged to the brush 22 through the injection holes of the injection nozzle 40. Therefore, the cosmetic powder in the cosmetic powder retaining tank 30 is finally injected to the brush 22 along the above air flowing passage.

[0043] As a consequence, the brush 22 is uniformly covered with the cosmetic powder, without any irregular covering, such that the user can paint the cosmetic powder on his or her face in the same manner as in the conventional practice.

[0044] After the painting ends, if the cylindrical member 56a of the pressure member 56 in the adjusting part 50 is raced in the opposite direction thereto, the horizontal member 56b screw-coupled on the inside of the cylindrical member 56a moves in the opposite direction to the arrow direction of FIG. 4 and in engagement therewith, the tubular body 54 of the adjusting part 50 moves to the top end of the hollow housing 52 by the elastic force of the elastic body 58. As a result, the oval holes H on the side of the tubular body 54 are kept in a closed state by means of the hollow housing 52.

[0045] In this case, if the state where the brush mounting member 20 and the adjusting part 50 are screw-coupled is released, the user can carry the cosmetic brush assembly in a more convenient manner.

[0046] On the other hand, when the cosmetic powder in the cosmetic powder retaining tank 30 is all consumed, the hollow housing 52 of the adjusting part 50 is separated and new cosmetic powder is filled in the cosmetic powder retaining tank 30. Next, the hollow housing 52 is re-assembled to the cosmetic powder retaining tank 30, such that the cosmetic brush assembly according to the present invention can be semi-permanently used.

[0047] Also, the opened top end of the cosmetic powder retaining tank 30 is in a closed state by means of the adjusting part 50 and the oval holes H on the side of the tubular body are kept in the closed state by means of the elastic force of the elastic body 58, thereby preventing the cosmetic powder in the cosmetic powder retaining tank 30 from leaking to the outside, such that the cosmetic brush assembly according to the present invention can be kept in a clean state.

[0048] On the other hand, FIGS. 6 and 7 show the cosmetic brush assembly according to another embodiment of the present invention, in which the similar reference numbers to those indicated in FIGS. 1 to 5 are indicated with a prime. Also, an explanation on the same parts in the one embodiment of the present invention will be avoided for the brevity of the description.

[0049] Referring to FIG. 6, first, the adjusting part 50′, which is mounted between the brush mounting member 20′ and the cosmetic powder retaining tank 30, includes the hollow housing 52′ and the tubular body 54. The hollow housing 52′ is screw-coupled to the cosmetic powder retaining tank 30 and fitted to the brush mounting member 20′. In other words, the brush mounting member 20′ is provided with reentrant grooves on the outside of the bottom end thereof, and in correspondence with the reentrant grooves, the hollow housing 52′ is provided with protrusions on the inside of the top end thereof. And, the tubular body 54 is elastically supported and inserted into the hollow portion of the hollow housing 52′. Therefore, in the state where the tubular body 54 is supported by means of an elastic body 58, the top end of the cosmetic powder retaining tank 30 is kept in the closed state by means of the adjusting part 50′.

[0050] Thereafter, as shown in FIG. 7, the brush mounting member 20′ is fitted to the top end of the hollow housing 52′ of the adjusting part 50′. At this time, the injection nozzle 40′, which is inserted into the hollow portion of the brush mounting member 20′, applies a force to the top end of the tubular body 54. As a consequence, the holes H formed on the side of the bottom end of the tubular body 54 are exposed to the interior of the cosmetic powder retaining tank 30.

[0051] Under this state, if the air pumping part 32 mounted on the bottom end of the cosmetic powder retaining tank 30 is manipulated, the air flowing to the cosmetic powder retaining tank 30 moves along the air flowing passage in the interior of the cosmetic brush assembly, thereby delivering the cosmetic powder to the brush, as discussed above.

[0052] On the other hand, referring to FIG. 6, a substantially cylindrical flange is attached on the bottom end of the injection nozzle 40′ inserted into the hollow portion of the brush mounting member 20. Also, a rubber packing material is disposed between the cylindrical flange and the top end of the tubular body 54.

[0053] Hereinafter, referring to FIGS. 8 and 9, an explanation of another brush mounting member of the cosmetic brush assembly according to the present invention will be discussed. In this case, the cosmetic powder retaining tank 30 and the adjusting part 50′ are discussed with reference to FIGS. 6 and 7.

[0054] Referring to FIG. 8, a brush mounting member 120 includes: a hollow housing 122 having a mounting part 122a which is mounted on the cosmetic powder retaining tank 30 or the top end of the adjusting part 50′ on the bottom portion thereof and a first hole on the center portion of the mounting part 122a; a substantially cylindrical member 124 inserted into the hollow portion of the hollow housing 122 and slidable in a length direction thereof; a brush support member 126 for mounting the brush on the top end thereof, installed on the inside of the cylindrical member 124 and forming a second hole coaxial to the first hole of the mounting housing 122 on the center portion thereof; and an injection nozzle 128 positioned in the interior of the brush 22 on the top end on which a plurality of injection holes are formed to pass through the first and second holes and having a powder flowing end disposed towards the cosmetic powder retaining tank 30.

[0055] On the other hand, the brush mounting member 120 according to the present invention further includes a cap 130 to which the mounting part 122a of the mounting housing 122 is assembled, for preventing the powder flowing end of the injection nozzle 128 from being exposed to the outside, in the state where the brush mounting member 120 is separated from the cosmetic powder retaining tank 30 or the adjusting part 50.

[0056] Therefore, in the state where the brush 22 is exposed to the outside of the mounting housing 122 and the cap 130 is removed out of the mounting part 122a of the mounting housing 122, the mounting part 122a is screw-coupled or fitted to the cosmetic powder retaining tank 30 or the top end of the adjusting part 50′. Next, the air pumping part 32 is manipulated and thus, the cosmetic powder in the cosmetic powder retaining tank 30 is uniformly injected to the brush 22 via the injection holes of the injection nozzle 128 along the air flowing passage.

[0057] After the painting ends with the cosmetic brush assembly according to the present invention, as shown in FIG. 9, the brush mounting member 120 is separated from the cosmetic powder retaining tank 30 or the adjusting part 50′ and then, the cap 130 is covered on the mounting part 122a of the mounting housing 122. The cylindrical member 124 is raised in the arrow direction and inserts the brush 22 in the interior thereof. Next, a cover (which is not shown in the drawing) is covered on the cylindrical member 124, thereby preventing the brush 22 from being exposed to the outside.

[0058] Referring to FIGS. 10 to 13b, on the other hand, the cosmetic brush assembly according to yet another embodiment of the present invention is embodied in the same manner as in FIG. 1, except that a first screw is formed on the outside surface of the top end of a tubular body 154 passing through the hollow portion of a hollow housing 152 and thus slidably mounted thereon, a second screw coupled to the first screw is formed on the center of a horizontal member 156b, a brush fixing member 24 for fixing the end of a brush 22, the brush fixing member being separable from a brush mounting member 20, and a cylindrical tube 26 installed on the center of the lower end of the brush 22, for smoothly moving the injection nozzle 40.

[0059] According to the cosmetic brush assembly of the yet another embodiment of the present invention, as shown in FIGS. 11 and 12, if a cylindrical member 156a rotates in a predetermined direction in the state where the first screw on the top end of the tubular body 154 is coupled to the second screw on the center of the horizontal member 156b, the horizontal member 156b moves downwardly, with a consequence that the tubular body 154 of the injection nozzle 40 moves downwardly. As a result, the oval holes H formed on the side of the tubular body 154 are opened to the interior of the cosmetic powder retaining tank 30, and in this state, if the air pumping part 32 operates, the cosmetic powder retained in the cosmetic powder retaining tank 30 is injected to the brush 22 along the flowing passage as mentioned above.

[0060] On the other hand, if the cylindrical member 156a rotates in an opposite direction, the tubular body 154 moves upwardly and as a result, the oval holes H are closed by the hollow housing 152.

[0061] As described above, the first screw on the top end of the tubular body 154 is coupled to the second screw on the center of the horizontal member 1 56b, such that the tubular body moves upwardly and downwardly in engagement with the rotation of the cylindrical member 156a. Hence, the cosmetic brush assembly of the yet another embodiment of the present invention does not require any elastic body for supporting the tubular body 154.

[0062] As apparently shown in the foregoing, a cosmetic brush assembly according to the present invention is capable of covering a brush with a cosmetic brush by the air pumping operation of an air pumping part, thereby ensuring a high grade of cosmetic brush assembly and preventing the cosmetic powder from leaking to the outside.

[0063] Additionally, a cosmetic brush assembly according to the present invention is capable of increasing an injection force of the cosmetic powder injected from a cosmetic powder retaining tank, thereby achieving a uniform dispersion of the cosmetic brush to the brush and adjusting an amount of cosmetic powder injected, thereby achieving a satisfied painting.

[0064] While the present invention has been described with reference to a preferred embodiment, the description is illustrative of the invention and is not to be construed as limiting the invention. Various modifications may occur to those skilled in the art without departing from the true spirit and scope of the invention as defined by the appended claims.
