TECHNICAL FIELD 
     The present invention relates to a mascara brush, and particularly, to a mascara brush capable of achieving the volume-up and curling of eyelashes by raising eyelashes with a mascara material applied, wherein the mascara brush is withdrawn from a mascara container, a button on a grip is pressed, and then the brush is bent in an arc shape by a working member within a brush base, to prevent mascara materials adhered to a mascara rod from staining the periphery of eyes or nose, thereby providing a convenient use. 
     BACKGROUND OF THE INVENTION 
     A make-up for eyelashes is generally used to embellish eyes and create a more beautiful face. A representative tool used for the make-up of eyelashes is mascara. The mascara is a cosmetic dedicated to eyelashes, which is applied to eyelashes to create voluminous and long eyelashes, and it is used with a mascara brush and a mascara material adhered thereto. That is, when making up eyelashes using the mascara brush, a mascara material is adhered to the mascara brush, and the mascara material adhered is evenly applied to eyelashes by combing and raising eyelashes using the mascara brush. The applying of mascara material to eyelashes and raising the eyelashes make the make-up of eyelashes more beautiful. Thus, a mascara brush is used for applying a mascara material to eyelashes and curling the eyelashes voluminously. 
     Generally, a mascara brush is integrated with a cap of a container containing a mascara material, the cap serves as a grip, and the brush is provided at a distal end of a straight brush rod associated with one end of the cap. 
     In the cap-integrated mascara brush, the brush and brush rod are immersed into the mascara material when the mascara brush is sealed by closing the container with the cap. Therefore, when making up eyelashes using such a mascara brush, as shown in  FIG. 1 , there is a problem that mascara materials adhered to the brush rod may stain a face, particularly the periphery of eyes or nose. 
     Further, mascara brush  1  is generally formed as a straight shape; however, such a straight brush may be unsuitable for curling curved eyelashes.

     DETAILED DESCRIPTION OF THE INVENTION 
     It should be noted that the interpretation of terms and words used herein are not limited to their common meanings known in the art, but they may be understood as any meaning and concept which conform to a technical spirit of the present invention based on the rule that the inventor can define appropriately the concept of a term to explain optimally the inventor&#39;s own invention. 
     Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings. 
     First, a mascara brush according to the present invention is shown in  FIGS. 2 and 3 . Main body M of the mascara brush consists of grip  100  comprising outer cap  110 , inner cap  120 , button cap  130 , brush  140 , control member  150  and working member  160 , and container  200 . 
     Outer cap  110  is formed as a hollow cylindrical body where the top and bottom are opened. A screw member is formed on the outer peripheral surface of the upper portion of outer cap  110 , button cap  130  is associated or separated by the screw member, and switch holder  152   a , battery holder  153   a  and inner cap  120  are sequentially associated in the inside. 
     Inner cap  120  has a screw member formed on the inner peripheral surface of the lower portion, which corresponds to a screw member formed on the outer peripheral surface of the mouth portion of container  200 . Inner cap  120  and container  200  are associated or separated by the screw member. Also, a septum is formed in the center of inner cap  120 , brush rod  122  is formed at the lower portion of septum, and terminal packing  155  is associated at the upper portion of septum. 
     Brush rod  122  is formed as a hollow rod body where one end may be inserted securely into the center of septum of inner cap  120  or may be integrated with inner cap  120 . Working member holder  166  and brush base  142  having brush hairs  144  are sequentially associated at the distal end of brush rod  122 . 
     Button cap  130  is formed as a cylindrical body where the bottom only is opened. Button  151  is associated at the center of the upper surface of button cap  130 , and a screw member is formed on the inner peripheral surface of the lower portion, which corresponds to the screw member formed on the upper peripheral surface of outer cap  110 . 
     Brush  140  has flexible, resilient and insulating properties, and has a form that brush hairs  144  are implanted into brush base  144  which is a tube type having one end opened. The brush base is flexible and resilient, and it may be formed of silicones or elastic polymers, for example Elastomer. Brush hairs  144  may be a brush implanted into brush base  142 , or they may be integrated with the brush base  142  where the brush hairs may be the same material as the brush base. 
     A working member  160 , a first plate  162  and a second plate  164  are inserted in the inside of brush base  142 . 
     Control member  150  which drives working member  160  comprises switch  152  mounted in switch holder  152   a  beneath button  151 , battery  153  inserted in the inside of battery holder  153   a , terminals (a, b, c), insert terminals (a 1 , b 1 ) and electric wires (a 2 , b 2 , b 3 ). 
     Terminal is located between +terminal of battery  153  and the bottom of switch holder  152   a . Terminal b is connected to insert terminal a 1  on the basis of terminal packing  155 , and the upper portion of terminal b is located at −terminal of battery  153 . Terminal c is connected to insert terminal b 1  on the basis of terminal packing  155 , and one end of terminal c is connected to wire b 3  which is connected to switch  152 . 
     Insert terminal a 1  is connected electrically to a first plate  162  through wire a 2  installed inside brush rod  122 , and insert terminal b 1  is connected electrically to a second plate  164  through wire b 2  installed inside brush rod  122 . 
     That is, if button  151  is pressed, electric current of battery  153  flows into the first plate  162  and the second plate  164  via the path of terminal a→terminal b→insert terminal a 1 →wire a 2 →first plate  162 →second plate  164 →wire b 2 →insert terminal b 1 →terminal c→wire b 3  by switch  152 . 
     Working member  160  is located in the inside of brush base  142 , and brush base  142  is associated at the lower end of working member holder  166  which is associated with brush rod  122 . 
     Working member holder  166  may be formed of ceramics to absorb heat from working member  160  and supply the heat to the first plate  162  and the second plate  164 . 
     Working member  160  is integrated with the first plate  162  and the second plate  164  of a thin metal plate where the first and second plates  162 ,  164  are superimposed vertically with the working member in the left and right sides. In this case, the first plate  162  is connected to insert terminal a 1  via wire a 2 , and the second plate  164  is connected to insert terminal b 1  via wire b 2 . 
     The first plate  162  and the second plate  164  of working member  160  are formed of two types of metal having different thermal expansion coefficients. The first plate  162  is formed of a metal having a high expansion rate under a heating condition (for example, nickel+manganese+iron or nickel+manganese+cupper or nickel+molybdenum+iron), and the second plate  164  is formed of a metal having a low expansion rate (for example, nickel+iron or nickel+cupper). If button  151  is pressed, the first and second plates  162 ,  164  are bent in an arc shape in the direction of the second plate by heat from electric current of battery  153 . 
     Container  200  is formed as an elongated cylindrical shape. The upper mouth portion of container  200  is associated with packing  201 , and the inside of container  200  is filled with a mascara material. Also, brush rod  122  and brush  140  of grip  100  are received in the inside of container  200 . 
     The mascara brush thus configured is withdrawn from mascara container  200  by turning and opening grip  100 . 
     In case of the mascara brush withdrawn, a mascara material is adhered to brush  140  of main body M (the mascara material is not shown). Therefore, eyelashes can be made up directly using the mascara brush. However, as previously described, when brush  140  and brush rod  122  are in line as shown in  FIG. 4 , mascara materials adhered to brush rod  122  stain the periphery of eyes, and the mascara brush is not used as it is. 
     According to the present invention, after mascara brush  140  is withdrawn from mascara container  200 , if button  151  on grip  100  is pressed, then brush  140  is bent in an arc shape as shown in  FIG. 5 . 
     That is, if button  151  on grip  100  is pressed, electric current of battery  153  flows into the first plate  162  and the second plate  164  via the path of terminal a→terminal b→insert terminal a 1 →wire a 2 →first plate  162 →second plate  164 →wire b 2 →insert terminal b 1 →terminal c→wire b 3  by switch  152 , and the first and second plates  162 ,  164  are bent in an arc shape in the direction of the second plate  164  by heat from electric current of battery  153 . As a result, flexible brush base  142  enclosing the outside of the first and second plates  162 ,  164  is bent in an arc shape at the center on the distal end of brush rod  121 . Thus, as shown in  FIG. 6 , eyelashes may be made up by curling eyelashes using brush  140  bent in an arc shape. In case of the mascara brush according to the present invention, brush rod  122  is handled away from the peripheral of eyes. Therefore, since brush rod  122  is not in contact with the peripheral of eyes, it is possible to prevent mascara materials adhered to the outside of brush rod  122  from staining a face. 
     After the use of the mascara brush, if button  151  is pressed, electric current of battery  153  is broken, and working member  160  bent in an arc shape recovers its original shape. Since this reverse mechanism is progressed by doing reversely works described above as appreciated by a person skilled in the art, the detail description for this will be omitted. 
     Although the present invention has been described in relation to embodiments illustrating the principle of the present invention, the present invention should not be limited to these configurations and functions described and shown above. It will be appreciated by a person skilled in the art that various modifications and variations may be made thereto without departing from the scope and spirit of the appended claims and it is to be understood that such modifications and variations and equivalents thereof fall within the scope of the present invention.
