Document Type and Number:
WIPO Patent Application WO/2012/008667
Kind Code:
A1
Abstract:
The present invention relates to a cosmetic case, in which a cosmetic solution in a case body is used and discharged in small quantities through a piston unit. The invention comprises: a case body (100), in which a cylinder (110) is equipped in a longitudinal direction therein such that a cosmetic solution (L) is contained and stored in the cylinder, and on which a container-shaped rotation support unit (120) is formed; a screw rod (200) which has an upper end that is inserted and coupled on the rotation support unit (120) of said case body (100) by a rotation member (210) in order to mediate a no-load operation thereon, has a lower end that is extended to the lower side of the cylinder (110) of said case body (100), and in which a discharge channel (220) is formed in a longitudinal direction; a piston unit (400) which is mounted on the middle part of said screw rod (200), and descends to come in contact with the wall of the cylinder (110) of said case body (100) as said screw rod (200) is rotated in a forward direction along with said rotation member (210), thereby discharging the cosmetic solution (L) stored in the cylinder (110) of said case body (100) to the upper part of said screw rod (200) through the discharge channel (220) of said screw rod (200); a rotation cap (300) which has an upper side (310) in which a discharge outlet (311) is equipped in the middle part thereof in order to be connected with an upper end of said screw rod (200), has a wall (320) that is formed in a cup shape having an open bottom so as to enclose the rotation support unit (120) of said case body (100) from the outside, and has an inner wall that is engaged with the rotation member (210) of said screw rod (200) in order to rotate said screw rod (200) from the outside; and rubber valves (500, 800) which are disposed in the discharge outlet(311) of said rotation cap (300), opening of said discharge port (311) by the pressure for discharging the cosmetic solution (L) that is discharged through said screw rod (200) as said screw rod (200) is rotated in the forward direction, and closing of said discharge outlet (311) by a self elastic restoring force if the rotation of said screw rod (200) is stopped.
