     DETAILED DESCRIPTION 
       [0019]    Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals refer to like elements throughout. 
         [0020]      FIG. 1  is an exploded perspective view illustrating a configuration of a syringe-type cosmetic container according to a preferred embodiment of the present invention,  FIG. 2  is a coupled perspective view illustrating a configuration of a syringe-type cosmetic container according to a preferred embodiment of the present invention, and  FIG. 3  is a cross-sectional view illustrating a configuration of a syringe-type cosmetic container according to a preferred embodiment of the present invention. 
         [0021]    Referring to  FIGS. 1 to 3 , a syringe-type cosmetic container according to a preferred embodiment of the present invention includes a syringe body  100 , an over cap  200 , and a piston  300 . 
         [0022]    The syringe body  100  accommodates contents therein. A nozzle part  110  having a discharge hole  111  through which the contents discharged are disposed on an end of one side of the syringe body  100 . A first screw thread  112  to which the over cap  200  may be screw-coupled is disposed on an outer circumferential surface of the nozzle part  110 . 
         [0023]    A handle part  120  for supporting a finger of a user when the over cap  200  is pressed to discharge the contents in a state in which a push bar  230  of the over cap  200  is inserted into a push bar insertion groove  310  of the piston  300  may be disposed on an outer circumferential surface of the syringe body  100 . 
         [0024]    The over cap  200  surrounds the nozzle part  110  and is detachably screw-coupled to the syringe body  100 . A second screw thread  210  is disposed on an inner circumferential surface of the over cap  200 , which contacts the first screw thread  112 , so that the second screw thread  210  of the over cap  200  is screw-coupled to the first screw thread  112  disposed on the outer circumferential surface of the nozzle part  110 . 
         [0025]    Also, a blocking rod  220  coupled to the discharge hole  111  defined in the nozzle part  110  to block liquid leakage of the contents is disposed on a central portion of the inside of the over cap  200 . 
         [0026]    The present invention has a feature in which the push bar  230  extending by a predetermined length from the upper end of the over cap  200  is integrally formed on the over cap  200 . The push bar  230  may be inserted into the push bar insertion groove  310  of the piston  300  to enable discharging of the contents by moving the piston  300  when the user presses the over cap  200 . 
         [0027]    Since the blocking rod  220  is disposed inside the over cap  200 , and the push bar  230  integrally extends from an upper end of the blocking rod  220 , the over cap  200  may provide both its original function for blocking the liquid leakage of the contents by means of the blocking rod  220  and the function as the pressing unit that moves the piston  300  to discharge the contents. 
         [0028]    The piston  300  may be slidably movable in a state in which the piston  300  is closely attached to an inner circumferential surface of the syringe body  100 . The present invention has a feature in which the push bar insertion groove  310  is defined in the piston  300  so that the push bar  230  is insertable. The push bar insertion groove  310  may have various shapes according to the shape of the push bar  230 . 
         [0029]    The front end of the piston  300  may have a shape corresponding to that of the nozzle part  110  of the syringe body  100  so that the contents accommodated in the syringe body  100  are completely exhaustible. 
         [0030]    A piston support  400  for preventing the piston  300  from being separated is coupled to an end of the other side of the syringe body  100 . The piston support  400  may have a hollow so that the push bar  230  is insertable and withdrawable. A seat protrusion  410  for supporting a lower end of the piston  300  is disposed on an end of the piston support  400 . 
         [0031]    Hereinafter, a method of using the syringe-type cosmetic container according to a preferred embodiment of the present invention will be described with reference to  FIGS. 4 to 6 .  FIGS. 4 to 6  are explanatory views illustrating a method of using a syringe-type cosmetic container according to a preferred embodiment of the present invention. 
         [0032]    Referring to  FIGS. 4 to 6 , in the syringe-type cosmetic container of  FIGS. 4 to 6  according to a preferred embodiment, when the screw-coupled state is released to separate the over cap  200  from the nozzle part  110  in the state in which the over cap  200  is initially screw-coupled to the nozzle part  110 , the discharge hole  111  that is closed by the blocking rod  220  of the over cap  200  may be opened. As described above, when the push bar  230  of the over cap  200  is inserted into the push bar insertion groove  310  of the piston  300  in the state in which the discharge hole  111  is opened, and then, the over cap  200  is pressed, the pressure may be transmitted to the piston  300  to move the piston  300 . Thus, the contents accommodated in the syringe body  100  may be pushed in an extruding manner and discharged through the discharge hole  111 . 
         [0033]    That is, according to the present invention, since the push bar  230  is integrally formed on the upper end of the over cap  200 , ordinarily, the discharge hole  111  may be closed by the blocking rod  220  of the over cap  200  to block liquid leakage of the contents. When the contents are discharged, the push bar  230  integrally formed with the over cap  200  may be coupled to the push bar insertion groove  310  and thus used as the pressing unit. 
         [0034]    Hitherto, the best mode was disclosed in the drawings and specification. While specific terms were used, they were not used to limit the meaning or the scope of the present invention described in claims, but merely used to explain the present invention. Accordingly, a person having ordinary skill in the art will understand from the above that various modifications and other equivalent embodiments are also possible. Hence, the real protective scope of the present invention shall be determined by the technical scope of the accompanying claims.
