Description:
This non-provisional application claims priority under 35 U.S.C. § 119( a ) based on Patent Application No. 2004-0066658 filed in Korea on Aug. 24, 2004, the subject matter of which is herein incorporated by reference. 
   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a dischargeable cosmetics case for liquid cosmetics such as liquid foundation or liquid lipstick for making-up and possible to forcibly discharge the same, if used, more particularly, including a cylindrical main body to contain the cosmetics and a piston connected to a screw bar to move downward and to apply pressure inside of the main body as the main body turns to any one direction, resulting in discharging of the liquid cosmetics contained in the main body outward. 
   2. Description of the Related Art 
   Generally, cosmetic products are classified into solid and/or powdery status, and liquid status. In recent years, liquid cosmetics in the form of lipstick or foundation for convenient use of consumers is developed, which is usually made of liquid cosmetics charged in a housing in the form of pencil and is discharging through an upper brush member of the housing when turning any part of the housing to right or left direction and forcibly pressing inner side of the housing. Various constructional forms of such pencil type cosmetics are proposed and practically used in applications concerned. 
   An embodiment of conventional cases discharging liquid cosmetics has typical construction, as illustrated in  FIGS. 6 and 7  of the accompanying drawings herein. 
   The above case usually includes a main body  101  to contain liquid cosmetics, a cosmetic brush  102  for discharging the cosmetics possible to make up and a cap  103  for protecting the cosmetic brush  102 . 
   Within the main body  101 , installed are a rod  104  having a piston  103  to press out the liquid cosmetics toward the cosmetic brush  102  side; a movable body  105  consisting of a nut member  105   a  screw-connected to the rod  104  and, simultaneously, fixed on wall of the main body  101  to assist movement of the rod  104  (movement to upper side), and a single-directional rotation guiding member  105   b  rotating to only direction to the nut member  105   a ; and a rod-movement cap  106  for rotating the rod  104 . 
   As described above, the conventional liquid cosmetics case has the piston  103  fitted into an engaging part  104   a  on front end of the rod  104 , thus, causes severe shaking (or vibration) of the piston  103  out of the rod  104 , in addition to, has a disadvantage of easy disconnection between the rod  104  and the piston  103  even by small impact. Another spring  107  is fitted into rear end of the rod  104 . The spring is directly supported by the rod-movement cap  106  at one end of the spring  107  to apply repulsive force to the single-directional rotation guiding member  105   b , so that the supported end interferes with the rod-movement cap  106  when the rod-movement cap  106  moves pivotally. Accordingly, the rod-movement cap  106  does not smoothly rotate and has a defect of generating noise. 
   Further, the conventional cosmetics case can turn to only the one direction due to the movable body  105  comprising the nut-member  105   a  and the single-directional rotation guiding member  105   b  but cannot rotate contrary to the above direction, that is, reverse-direction, whereby it necessarily causes leak of the liquid cosmetics if the case is under weak impact or pressure and/or positioned upside down. 
   Still further, the conventional case with the above construction has a complex structure to lead to increasing of production cost thereof. 
   SUMMARY OF THE INVENTION 
   It is, therefore, an object of the present invention is to solve the above problems, in particular, to provide a cosmetics case including a main body and a piston fixed to bottom portion of a pipe-type screw bar hollowed inside, and a reversing-resistant ball within a nozzle fitted in and connecting to top end of the screw bar, wherein the screw bar turns and presses the piston downward depending on rotation of the main body, in turn, applies pressure inside of the main body containing liquid cosmetics to render the cosmetics to pass through the screw bar and the nozzle, then be discharged outside. After completion of use, it is possible to prevent the cosmetics from being discharged by the reversing-resistant ball. 
   Therefore, the present inventive cosmetics case ensures discharging of the liquid cosmetics with a simple structure so that it can improve commercial value of goods and availability, eliminate noise and simplify construction of the case, thereby rendering production of the cosmetics case economically advantageous.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
   The present invention will be described in more detail be reference to the accompanying drawings and following embodiments which are presented for purpose of illustration and should not be construed to limit the scope of the invention thereto. 
     FIGS. 1 to 5  shows a cosmetics case according to the present invention. 
   A cosmetics case  1  of the present invention includes generally a cylindrical main body  10  containing cosmetics  100  at bottom portion of the case  1 ; and an upper movable body  20  arranged with a nozzle member  40  and a discharging member  30  connected on a lop portion of the body  10 , wherein both of upper and lower screw-bars  62  and  64  and a piston  66  are mounted inside the main body  10 , and the upper movable body  20  is integrated together with the main body  10 . 
   The body  10  is in a form of cup having open top and closed bottom parts and serves as a press cylinder and, at the same time, stores the liquid cosmetics  100  therein. A connection sill  12  is formed on outer top side of the body  10  in order to render the upper movable body  20  to be fixed at its position without separation and possible to carry out free-rotation. 
   Alternatively, the upper movable body  20  coupled to the body  10  has a connection groove  22  its inner lower side, which is joined to the connection sill  12  and a concave and convex part  24  (hereinafter referring to as “uneven part”) in the form of screw thread, which is placed above the connection groove  22  and fitted into a screw-guidance ring  50  described below. The upper movable body  20  is integrated with the nozzle member  40  having a nozzle  42  extended downward from a top portion of the upper movable body  20 . 
   On top surface of the nozzle member  40 , formed is a distribution groove  44  in a concave form to evenly distribute the cosmetics  100  over wide area when discharging the cosmetics  100  through the nozzle  42 . 
   A reversing-resistant ball  46  is entered in top portion of the nozzle  42  to prevent the cosmetics  100  from leaking when the cosmetics  100  is not used. 
   The discharging member  30  which is coupled on top portion of the nozzle member  40  has a number of exhausting holes  32  to discharge the cosmetics  100  already transferred in the distribution groove  44  through the nozzle  42  outside. A cap  80  is mounted on top portion of the discharging member  30  and coupled with the upper movable body  20 . 
   In addition, the above respective upper and lower screw bars  62  and  64  have larger and smaller diameters and are screw-connected each other. A piston  66  is fixed to bottom end of the lower screw bar  64  and tightly fitted inside the body  10 . 
   The upper and the lower screw bars  62  and  64  are connected together in the same manner as shown in  FIGS. 3 to 5 . More particularly, the upper screw bar  62  having the screw thread  62   a  over entire part of outer surface thereof is fitted with the screw-guidance ring  50 , while another screw thread  62   b  being partially formed on inner lower side of the upper screw bar  62  and screw-connected with the lower screw bar  64 . 
   Accordingly, the upper screw bar  62  moves up and down along the screw-guidance ring  50  fitted into the uneven part  24  and fixed in its position, while the lower screw bar  64  can move up and down along the upper screw bar  62 . 
   As shown in  FIG. 2 , the screw-guidance ring  50  has a threading line  50   a  inside to be fitted with the upper screw bar  62  and, simultaneously, projections  52  around peripheral side of the screw-guidance ring  50  to be inserted between concaves of the uneven part  24  formed inside the upper movable body  20  in order to inhibit rotation thereof. 
   The present inventive case constructed as described above is assembled as shown in  FIG. 3 . 
   In the main body  10 , desirable amount of the cosmetics  100  is stored. The nozzle member  40  coupled with the discharging member  30  is connected to the upper movable body  20 , and connection groove  22  of the upper movable body  20  is connected to the connection sill  12  of the main body  10  so that the main body  10  and the upper movable body  20  can be integrated together in a rotation-possible manner. 
   The lower screw bar  64  is fitted into the piston  66  not to move, then, into the upper screw bar  62 . The screw-guidance ring  50  is screw-connected to outer side of the upper screw bar  62 . 
   As the upper and the lower screw bars  62  and  64  are connected together, the screw-guidance ring  50  is connected with the uneven part  24  in the upper movable body  20 . More particularly, the projections  52  around peripheral side of the screw-guidance ring  50  are inserted between the concaves of the uneven part  24  to inhibit rotation of the screw-guidance ring  50 . 
   Functional effect of the present invention having such construction described above will be more understood with reference to practical use according to the following description. 
   Firstly opening the cap  80  then turning the main body  10  to one direction by one hand (for example, clockwise direction) while gripping the upper movable body  20  by the other hand when the cosmetics  100  is used for the make-up, the piston  66  rotates together with the main body  10  because it is tightly engaged to the main body side  10 . Therefore, the lower screw bar  64  connected to the piston  66  is also under rotation and naturally moves downward to press the main body  10  containing the cosmetics  100  because it is screw-connected to the upper screw bar  62  (at this time, the upper screw bar is supported by the screw-guidance ring and is placed in its position without movement). 
   Accordingly, with desired pressing force of the piston  66 , the cosmetics  100  is delivered into wide area of the distribution groove  44  through the nozzle  42  and simultaneously discharged through the exhaust holes  32 , thereby being used for the make-up (see  FIG. 4 ). 
   In this case, the reversing-resistant ball  46  is opened by applying pressure to allow the cosmetics  100  to be transferred. If the pressure is removed, the reversing-resistant ball  46  returns to its original position to help prevention of the cosmetics  100  from passing through. 
   Meanwhile, the present cosmetics case may further comprise any make-up aids (not shown) such as a sponge type member or a brush enveloping outer top portion of the discharging member  30 , optionally for convenience of manufacturers, in case where the cosmetics  100  is discharged outside through the exhaust holes  32 . 
   Using such a case mentioned above at the first time, the lower screw bar  64  fixed with the piston  66  moves downward to press the main body  10  when the main body is turned to any direction, thereby ensuring the make-up. In case the lower screw bar  64  continuously falls down, a projection sill  68  is engaging to another projection sill  69  on inner lower end of the upper screw bar  62  to block rotation thereof then prevent the downward movement of the lower screw bar  64 , resulting in integration of the lower screw bar  64  with the upper screw bar  62 . 
   Under the condition described above, if the main body  10  turns continuously, the turning force is delivered to the upper screw bar  62  since both of the upper and the lower screw bars  62  and  64  are integrated together. Such upper screw bar  62  is screw-connected to the screw-guidance ring  50  fixed at its position, thus, turns to any direction to move downward. 
   Briefly, the present inventive case is characterized in that the lower screw bar  64  firstly moves downward and applies pressure inside of the main body  10  to discharge the cosmetics  100  in case where the main body  10  turns to any desirable direction to provide the cosmetics  100 ; subsequently, the upper screw bar  62  falls down to discharge the remaining cosmetics  100 . With respect of the present case, when the cosmetics  100  is completely drained out, both of the upper and the lower screw bars  62  and  64  fall down to make the piston  66  to contact bottom of the main body  10  as shown in  FIG. 5 . 
   As described above, the cosmetics ease of the present invention comprises both of upper and lower screw bars which move relatively each other as integrated by screw-connection between the upper and the lower screw bars to apply pressure cosmetics contained in a main body, and a piston moving by means of the above screw bars to accurately deliver the pressure and ensure discharging of the cosmetics, so that it can improve commercial value of goods and availability, eliminate noise and reduce production cost by simplification of parts for the case, thereby rendering production of the cosmetics case economically advantageous. 
   The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
