Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims the benefit of Korean Application No. 10-2013-0061776 filed on May 30, 2013 with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. 
     TECHNICAL FIELD 
     The present invention relates to a tubular case for cosmetics, and more particularly, to a tubular case for cosmetics in which an opening/closing protrusion is inserted in close contact in a discharge hole to prevent leakage of make-up and an O-ring is fitted on an upper stepped portion of a cosmetic discharge member to seal the inner side of a lower cylindrical protrusion. 
     BACKGROUND ART 
     A cosmetic container that discharges make-up in the container has been disclosed in Korean Patent Application NO. 2009-83088, in which an inlet having an anti-slide protrusion and a thread is formed at the top of the container, a flange-shaped packing body with an insertion hole at the center is inserted in the inlet, a guide groove having a center hole at the top is formed, a position control member having a thread and an anti-slide protrusion therein and a coupling ring having a locking groove around a bar having a discharge hole at the top are vertically disposed, an inlet communicating with the discharge hole of the bar is formed through the bottom, an embedding pipe with a brush embedded is fitted on a holder by coupling a rotary member having a stopper and a guide protrusion, and is inserted in a receiving groove of a fixing member having a fitting groove around the lower end and a locking protrusion at the upper end. When the cosmetic container is used, the packing body and the position control member are fixed at the upper portion of the container and the rotary body that rotates a distance corresponding to the size of the guide groove on a position control member is rotated, so the inlet at the lower end of the bar vertically disposed at the upper portion of the rotary body opens/closes an opening at the lower end of the insertion groove formed at the center of the packing body, and accordingly, make-up in the container is discharged and blocked. 
     This cosmetic container of the related art has a complicated structure, so the manufacturing cost is high, and there are many parts, so assembling the parts takes large labor costs and it is not economical. Further, when it is used, the make-up in the container is supposed to go through a phased line from the opening of the insertion groove formed in the packing body to the discharge hole of the rotary body, so the make-up stops in the phased discharge line and cannot be smoothly discharged, or the make-up leaks due to unstable sealing while the container is carried.

     BEST MODE 
     The present invention provides a lobular case tor cosmetics that includes: a case made of a material that can be pressed by a hand and capable of keeping make-up; a cosmetic discharge member thread-fastened to an inlet to the top of the case; a cylindrical brush cap fitted on the cosmetic discharge member, moved up/down by elastic force of a spring therein, and keeping a brush on the top; and an upper cap covering the top of the cylindrical brush cap and thread-fastened to the lowermost stepped portion of fee cosmetic discharge member. 
     Mode For Invention 
     Hereinafter, exemplary embodiments of the present invention will be described in detail wife reference to the accompanying drawings. In the description of fee present invention, well-known configurations or functions are not described in detail when it is determined that they may make the spirit of the present invention unclear. 
     [Embodiment 1] 
       FIG. 1  is a view illustrating the external appearance of a tabular case for cosmetics of the present invention,  FIG. 2  is an exploded perspective view illustrating the tubular case for cosmetics of the present invention,  FIG. 3  is a cross-sectional view illustrating the tubular case for cosmetics of the present invention that is open,  FIG. 4  is a cross-sectional view illustrating the tubular case for-cosmetics of the present invention that is closed, and  FIG. 5  is a cross-sectional view taken along line A-A in  FIG. 2 . 
     As illustrated in  FIGS. 1 to 5 , a tabular ease for cosmetics of the present invention includes: a case  10  made of a material that can be pressed by a hand and capable of keeping make-up; a cosmetic discharge member  20  thread-fastened to an inlet  11  to the top of the case  10 ; a cylindrical brush cap  40  fitted on the cosmetic discharge member  20 , moved up/down by elastic force of a spring  30  therein, and keeping a brush  41  on the top; and an upper cap  50  covering the top of the cylindrical brush cap  40  and thread-fastened to the lowermost stepped portion  21  of the cosmetic discharge member  20 . 
     The cosmetic discharge member  20  fanned in a cylindrical shape has first and second stepped portions  23  and  24  of which the diameters decreases from the lowermost stepped portion  21  to the upper stepped portion  22 , a ring-shaped packing  25  fitted on the bottom of the upper stepped portion  22  to prevent make-up from leaking out of the case  10 , a circular bar-shaped opening/closing protrusion  26  protruding through the center of the top front the bottom inside the upper stepped portion  22 , and a plurality of holes  27  formed symmetrically to each other such that make-up is discharged around the opening/closing protrusion  26 . 
     The cylindrical brush cap  40  has: a discharge hole  42  formed such that make-up is discharged to the center of the lower end of the brush  21  kept at the center of the top of the brash cap and permeates into the brush  21 ; a circular protrusion  43  formed around the bottom inside the brush cap and locked to an outer circular protrusion  23   a  formed around the upper portion of the first stepped portion  23  of the cosmetic discharge member  20 ; a lower cylindrical protrusion  44  cylindrically protruding under the top where the brush  41  is kept and receiving the upper stepped portion  22  of the cosmetic discharge member  20 ; and an outer stepped portion  45  partially protruding at a lower portion to be moved down by a stepped groove  51  formed around the inner side of an upper cap  50  when it is covered by the upper cap  50 . 
     An O-ring  28  is fitted on the upper portion of the upper stepped portion  22  to seal the inner side of the lower cylindrical protrusion  44 . 
     Next, operation of the tubular case for cosmetics of the present invention having the configuration described above is described. 
     First, when the upper cap  50  is opened, the cylindrical brush cap  40  pressed by the stepped groove  51  formed around the inner side of the upper cap  50  is moved up by elastic force of the spring  30  and accordingly the opening/closing protrusion  26  is separated out of the discharge hole  42 . 
     In this state, when the case  10  is pressed, make-up therein is discharged through the discharge hole and permeates into the brush, so a user can put the make-up on his/her face using the brush  41 . 
     As described above, since a user makes up using the brush  41 , it is possible to prevent the problem in the related art that when a user puts on make-up with a hand, the make-up permeates into the hand and loses before being put on a lace and is contaminated by the hand. Further, since the opening/closing protrusion is inserted in close contact in the discharge hole and the inner side of the lower cylindrical protrusion is sealed by fitting an O-ring on the upper stepped portion of the cosmetic discharge member, make-up is prevented from leaking. 
     As described above, although detailed embodiments of the present invention were described above, the present invention may be easily modified by those skilled in the art and those modifications should be construed as being included in the spirit of the present invention described is claims.
