Claim:
A nail polish container comprising: an outer barrel having a first open end and a second open end, said first open end having a reduced rim; a cone-shaped dispense nozzle coupled to said reduced rim of said outer barrel, said cone-shaped dispense nozzle having a conic outlet opening that is made elliptic in shape; a brush fitted in said cone-shaped dispense nozzle and having bristles uniformly distributed by said conic outlet opening of said cone-shaped dispense nozzle; a dispense tube seat received in an open end of said cone-shaped dispense nozzle and bearing against an inner wall of said open end of said cone-shaped dispense nozzle, said dispense tube seat having a dispense tube, said dispense tube having a first end extending into said brush and a second end extending into said first open end of said outer barrel, said second end of said dispense tube having an opening delimited by a circumferential wall that defines an inwardly recessed notch to serve as an inlet passage for liquid inflow; a refill container containing a cosmetic liquid and inserted into said second open end of said outer barrel; a mounting cap engaged with an open end of said refill container and having a resilient deformable central bore; a sealing member fitted in said mounting cap; a tubular sleeve having a U-shaped cross-section and having a plurality of elongate openings defined and lined up circumferentially on a circumferential surface of said tubular sleeve, said tubular sleeve being fitted into said refill container, a volume-regulating valve seat fitted in said tubular sleeve; a plunger bar fitted in said tubular sleeve and having an end extending through said volume-regulating valve seat out of said tubular sleeve, said plunger bar having an end in abutting engagement with said second end of said dispense tube; a resilient piece fitted in said tubular sleeve and tending to force said plunger bar toward said mounting cap thereby closing said elongate openings of said tubular sleeve and therefore preventing said cosmetic liquid in said refill container from flowing through said dispense tube into said brush; and said dispense tube having a diameter that is fit into and corresponds to a diameter of said resilient deformable bore of said mounting cap in hermetic engagement and positioning manner so as to prevent leakage; an outer cap engageable with said cone-shaped dispense nozzle; wherein when in use, by depressing and retracting said refill container into said outer barrel, said tubular sleeve will be moved with respect to said plunger bar towards said dispense tube seat thereby opening said elongate openings of said tubular sleeve and therefore enabling said cosmetic liquid in said refill container to flow through said dispense tube into said brush, and when said refill container is released, said resilient piece returns said tubular sleeve back to close said elongate openings of said tubular sleeve thus preventing cosmetic liquid in said refill container from flowing through said dispense tube into said brush.
