Title: Discharge structure of the cosmetics brush

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS  
      This application claims the benefit of Korean Patent Application No.  10-2005-0104670 , filed on Nov.3, 2005, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.  
     BACKGROUND  
      1. Field of the Invention  
      The present invention relates to a discharge structure of the cosmetic brush, and more particularly, to a discharge structure of the cosmetic brush capable of discharging a constant amount of powder to a brush side, regulating the discharge of powder freely, and refilling powder by separating an inner moving body.  
      As an inner moving body is pushed to the brush side, a conical elastic part, forming a coupler coupled by screws to the upper part of the inner moving body, is compressed, and at the same time, a vertical pole moves to the central part of the inner moving body, so as the inner hole is opened, a constant amount of powder is discharged to the brush side through the penetrating hole, the inner hole and the powder transporting tube.  
      As the inner moving body is pushed, the inner moving body descends and returns by the expansive force of the conical elastic part and the elastic force of the spring, thread formed to the lower circumference of the vertical pole. Then the inner hole is closed by the sealing ring, formed to the circumference of the vertical pole, and the powder is prevented from being discharged. So the discharge of the powder can be easily controlled semi-automatically by the conical elastic part, formed at the coupler, and the spring.  
      Also, because the assembling and disassembling of the coupler of the inner moving body are easy, the inner moving body can be opened for refilling powder when powder is used up.  
      2. Discussion of Related Art  
      Generally speaking, cosmetics are divided into solid state or liquid and the combined liquid state cosmetics. And recently, some cosmetics like lipsticks or foundation are supplied as liquid, and the liquid is usually contained in the pencil-shaped container. And when a part of the container is rotated, the cosmetics in the container are discharged to the upper brush so that a user can apply make-up. And various types of structures have been suggested and used.  
      The conventional cosmetics brush was separately stored with powder, so carrying and keeping them were not easy.  
      However, recently, powder is contained in the container-shaped body, and the powder is discharged to the brush side by the air pressure. And various types have been suggested and used. And it was disclosed in Utility Model No. 0253672, and  FIG. 11  and  FIG. 12  show the constitution. [ 0008 ] As illustrated in  FIG. 11  and  FIG. 12 , it is composed of the first body  102  where cosmetics powder  103  is contained as the upper and the lower parts are in the opened pipe type; the second body  106  where it is coupled at the circumference of the lower side of the first body  102 , a discharge hole  107  is formed at the central part of the upper side, and a brush  108  connected with the discharge hole  107  is equipped; a vertical transfer axis  109  where a spring  110  is coupled at the circumference of the front end, the front end is coupled with the discharge hole  107  of the second body  106 , and the spring  110  is supported at the front end circumference of the discharge hole  107 ; the upper cap  113  that supports as it makes the front end part of the vertical transfer axis  109  protruded by being coupled at the front end of the first body  102 .  
      According the constitution like the above, when a user applies make-up using the cosmetics brush, the user uses the brush by pressing the button  102  protruded to the upper side by being coupled at the front end of upper and lower transfer axes  109 . At this point, the transfer axis  109  moves vertically by the spring  100  at the front end of the transfer axis  109 . And as the transfer axis  109  moves vertically, the power  103  contained inside the body  102  is supplied to the outside, that is, the brush  108  through the discharge hole  107  where the front end of the transfer axis  109  is formed at the second body  106  for convenient use.  
      At this point, the cosmetics powder discharged to the brush through the discharge hole  107  is supplied to the brush  108 , as the end front of the transfer axis  109  directly penetrates the discharge hole  107 .  
      However, in case of the conventional cosmetics brush like the above, powder  013  is discharged to the brush  108  by the front end part of the transfer axis  109 . It not only cannot discharge power constantly because of the structure of the transfer axis  109 , but also makes a user inconvenient because the powder  103  is discharge to the brush  108  side only because of the shaking of the brush.  
      Also, the button  112  formed at the upper cap  113  side is always in the protruded state to the outer side by the elasticity of the spring  110 . So if it is bumped into any hand baggage while a user carries it or it is given any external force, the button  112  can be moved, then the power  103  can be unnecessarily discharged to the brush  108 , damaging other belongings. And also, when it is stored in a wet place or it is not used for a long time, the discharge becomes difficult because the powder  103  contained inside the first body  102  and the power remaining in the discharge hole  107  are hardened.  
     SUMMARY OF THE INVENTION  
      In order to solve the above-described problems, it is an object of the present invention to provide a discharge structure of the cosmetic brush capable of discharging a constant amount of powder to a brush side, regulating the discharge of powder freely, and refilling powder by separating an inner moving body when powder is used up.  
      In order to achieve the foregoing and/or other objects of the present invention, according to a first aspect of the present invention, as an inner moving body is pushed to the brush side, a conical elastic part, forming a coupler coupled by screws to the upper part of the inner moving body, is compressed, and at the same time, a vertical pole moves to the central part of the inner moving body, so as the inner hole is opened, a constant amount of powder is discharged to the brush side through the penetrating hole, the inner hole and the powder transporting tube.  
      According to a second aspect of the present invention, as the inner moving body is pushed, the conical elastic part is compressed, then the inner hole is opened, then the powder is discharged to the brush side. At the same time, the inner moving body descends and returns by the expansive force of the conical elastic part and the elastic force of the spring, thread formed to the lower circumference of the vertical pole. Then the inner hole is closed by the sealing ring, formed to the circumference of the vertical pole, and the powder is prevented from being discharged. So the discharge of the powder can be easily controlled semi-automatically by the conical elastic part, formed at the coupler, and the spring. And because the assembling and disassembling of the coupler of the inner moving body are easy, the inner moving body can be opened for refilling powder when powder is used up.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS  
      Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.  
       FIG. 1  is a perspective view of the present invention in the state the cap is opened,  FIG. 2  is an exploded perspective view of the present invention,  FIG. 3  is a sectional view of the present invention, and  FIG. 4  is a sectional view of the present invention at the state the inner moving body is pushed up.  
      The present invention is composed of a inner moving body  10  where a sealing ring  15 , in which a spring  16  is interposed to the upper part of a support  13  in which a penetration hole  14  is formed, is formed, and a vertical pole  17 , in which a thread groove  18  is formed, is put in;  
      an outer upper moving body  20  where it is coupled to the upper part of the inner moving body by a coupler  24 , a conical elastic part  25  is connected to the upper part of the coupler  24 , and the vertical pole  17  is thread coupled to the inner hole  26  formed to the central part;  
      an inner upper moving body  30  where it is equipped with a powder transporting tube  32  to the inside, a brush  33  is thread coupled to the upper side, a brush cover  34  is formed to the outside, and it is coupled to the inside of the outer upper moving body  20 ;  
      Where the outer lower moving body  40  is thread coupled to the lower circumference of the outer upper moving body  20 , and a cap  50  is coupled to the upper side.  
      As the inner moving body is pushed, a conical elastic part  25  is compressed, and an inner hole  26  is opened. Then not only powder is discharged to the brush side  33 , but also the inner moving body  10  descends and returns by the expansive force of the conical elastic part  25  and the elastic force of the spring  16  thread formed to the lower circumference of a vertical pole  17 . Then the inner hole  26  is closed by the sealing ring  15  formed at the circumference of the vertical pole  17  so that the power is discharged. So it is possible to freely regulate the discharge of the power semi-automatically by the conical elastic part  25  and the spring  16  formed at the coupler  24 .  
      And the accompanying drawings can be described in details as follows.  
      As described at  FIG. 1  to  FIG. 4 , the present invention includes a container  11  containing powder to the inside of the inner moving body  10 , and an outer screw part  12  at the outer upper circumference.  
      An inner hole  26  is formed at the central part to the outer screw part  12  formed to the inner moving body  10 , and the outer upper moving body  20  is screw coupled as the coupler formed by the conical elastic part to the lower part.  
      A support  13 , where a penetrating hole  14  is formed between the upper part of the inner moving body  10  and the coupler  24 , is coupled, and the vertical pole  17  is thread coupled by penetrating the inner hole  26 .  
      At this point, the sealing ring  15 , where the spring  16  is interposed to the lower circumference of the vertical pole  17 , seals by being positioned at the inner hole  26 , as described at  FIG. 3 , and the above spring  16  keeps pushing the inner moving body  10  by the elastic force by being supported at the lower part of the inner hole  26 .  
      On the other hand, the inner upper moving body  30  is thread coupled to the inside of the outer upper moving body  20 , the inner upper moving body is equipped with the powder transporting tube  32 , the brush  33  is thread coupled, and the brush cover  34 , which gathers the brush  33  as it slides at the outer side, is coupled.  
      The outer lower moving body  40  is thread coupled to the lower circumference of the outer upper moving body  20 , and the inner moving body  10  is located to the inner side of the outer lower moving body  20 .  
      And the cap  50  is thread coupled to the upper circumference of the outer upper moving body  20 . In this way, the cosmetics brush  1  is constituted.  
      The effects by the present invention can be explained as follows.  
      As described at  FIG. 3 , the cosmetics brush  1  of the present invention is in the state that the force is not given to the lower part of the inner moving body in the normal situation  20 , so the inner moving body  10 , where the coupler  24 , formed to the lower part of the outer upper moving body  20 , is thread coupled, is in the descended state, and the cap  50  is coupled to the upper side, and it is in the closed state.  
      So the support  13 , where the penetrating hole  14  is formed to the lower part of the vertical pole  17  between the upper part of the inner moving body  10  and the coupler  24 , is in the coupled state. And the vertical pole  17  is in the state where it is located at the inner part of the powder transporting tube  32  formed to the inside of the inner upper moving body  30  by penetrating the inner hole  26  formed to the inner central side of the outer upper moving body  20 .  
      At this point, the sealing ring  15 , formed to the lower part of the vertical pole  17 , is in the same state with the inner hole  26 , and the sealing ring  15  is closing the inner hole  26 .  
      Also, the auxiliary brush  19  is thread coupled to the thread groove  18  formed to the upper part of the vertical pole  17 .  
      Like the above, if the lower part of the inner moving body  10  is pressed in the state that the inner hole  26  is sealed by the sealing ring  15  of the vertical pole  17 , the conical elastic part  25 , formed to the lower part of the coupler  24 , is compressed, and the inner moving body  10  ascends to the inner part of the outer lower moving body  40 .  
      Therefore, as described at  FIG. 4 , as the inner moving body  10  ascends, the sealing ring, which was sealing the inner hole  26  by being formed to the lower circumference of the vertical pole  17 , deviates from the inner hole  26 , and the inner hole  26  is opened. And the spring interposed to the lower part of the vertical pole  17  comes to the compressed state.  
      So, in the state the inner hole  26  is opened, as a user applies make-up, gripping the cosmetics brush  1  upside down, the powder contained in the container  11  of the inner moving body  10  is discharged to the brush side through the penetrating hole  14 , the inner hole  26  and the powder transporting tube  32 , so a user can apply make-up.  
      Therefore, after the make-up is finished, when the force pressing the inner moving body is released, as the conical elastic part  25  formed to the upper part of the coupler  24  is expanded, the inner moving body  10  descends. Then the sealing ring of the vertical pole  17  also descends, and closes the inner hole  26 . In this way, the powder is prevented from being discharged to the brush  33  side, and the powder does not leak when it is not used.  
      On the other hand, the spring  16 , interposed at the lower part of the above vertical pole  17 , helps the inner moving body  10  to descend as the conical elastic part  25  is expanded, so helps the inner moving body  10  to easily return to the original state.  
      Therefore, when a user presses the inner moving body  10 , the inner hole  26  is opened, so the powder is easily discharged, and when the force to the inner moving body  10  is released, the inner hole  26  is easily closed.  
      Also, the inner moving body  10  and the coupler  24  are coupled by screws, so the assembling and disassembling are easy. So when the powder contained in the inner moving body is used up, it can be refilled by opening the inner moving body  10 .  
      In the drawing of the invention, it is described that the brush  33  part is directing to the upside for convenience. But in the real use, a user uses in the state that the brush  3  part is directing to the downside.  
       FIG. 5  is a sectional view of the first embodiment according to the present invention, and  FIG. 6  is a sectional view of the first embodiment according to the present invention at the state the inner moving body is pushed up.  
      The inner groove  27 , where the inner hole  26  is formed to the inner central part of the outer upper moving body  20 , is formed. And the vertical pole  17 , where the sealing step wheel  15   a  is formed to the circumference by penetrating the inner hole  26 , is thread coupled. In this way, the cosmetics brush  1   a  is discharged.  
      As the inner moving body  10  is pushed to the upper part, as described at  FIG. 6 , the sealing step wheel  15   a , formed to the circumference of the vertical pole  17  sealing the inner hole  26 , descends, and the inner hole  26  is opened. The spring  16  supported at the inner groove  27  goes to the compressed state.  
      So the powder, contained at the container  11  of the inner moving body  10  through the inner hole  26  opened by the deviation of the sealing step wheel  15   a , is transported to the powder transporting tube  32  through the inner hole  26  after passing by the penetrating hole  14 , and is discharged to the brush  33  side.  
      Also, the inner moving body  10  is coupled with the coupler  24  by screws. And because the assembling and the disassembling are easy, it can be easily refilled when the powder contained in the inner moving body  10  is used up.  
       FIG. 7  is a sectional view of the second embodiment according to the present invention, and  FIG. 8  is a sectional view of the second embodiment according to the present invention at the state the inner moving body is pushed up.  
      The discharge structure of the cosmetics brush  1   b  contains liquid cosmetics. As the inner moving body  10  is pushed to the upper part, the inner hole  26  is opened as the sealing step wheel, formed to the upper part of the vertical pole  17  sealing the upper part of the inner hole  26 , descends, and the inner hole  26  is opened. And the spring goes to the compressed state.  
      So as the sealing step wheel  15   a  is deviated, liquid cosmetics(For example, a hair dye) contained the container  11  of the inner moving body  10  pass by the penetrating hole  14 , and are discharged to the hair brush  33   a  side through the inner hole  26 . So a user can apply a hair dye, using the hair brush  33   a  and the teeth of a comb  33   a.    
       FIG. 9  is a sectional view of the third embodiment according to the present invention, and  FIG. 10  is a sectional view of the third embodiment according to the present invention at the state the inner moving body is pushed up.  
      As described at the second embodiment, the discharge structure of the cosmetics brush  1   c  uses liquid cosmetics by containing liquid cosmetics. And as the inner moving body  10  is pushed to the upper side, as described at  FIG. 10 , the sealing step wheel  15   a , formed to the upper part of the vertical pole  17  sealing the upper side of the inner hole  26 , descends, and the inner hole  26  is opened. And liquid cosmetics(For examples, liquid cosmetics for eyeliners or nail coloring), contained in the containing part  11  of the inner  10  through the opened inner hole  26 , are discharged to the brush  33  part through the inner hole  26 .  
      Therefore, cosmetics brushes  1   a    1   b    1   c  of the first, the second and the third embodiments show the same effects with the cosmetics brush  1  of the present invention.
