Patent ID: 7988377

Claim:
A device for dispensing a cosmetic liquid preparation, comprising: a collapsible tubular inner compartment for housing a first cosmetic liquid material therein and comprising an axial projecting first opening at one end; a collapsible tubular outer compartment for housing a second cosmetic liquid material therein, the second cosmetic liquid material being different from the first cosmetic liquid material, and the inner compartment being disposed in the outer compartment, the outer compartment comprising an axial projecting second opening at one end with the first opening disposed therein, and a mating member around the second opening; a valve assembly comprising a passageway having a rear radial tunnel, the passageway being fitted in the second opening, a spring biased hollow plunger having a forward annular flange and a rear projection adapted to slide in the passageway and block the tunnel when the device is in an inoperative position; and a dividing member disposed in the rear projection and comprising an inner channel, an outer channel, and a block disposed in the first opening for blocking the first opening in the inoperative position; an outlet assembly having a rear portion fixedly fastened in the bore of the plunger; and a cap comprising an internal receiving space and a corresponding mating member adapted to secure to the mating member for covering both the outlet assembly and the valve assembly and fastening the flange; whereby for dispensing the cosmetic liquid preparation, an individual unfastens and removes the cap from the device to unfasten the flange such that the plunger is pushed forward to clear the tunnel to permit the second cosmetic liquid material to be in fluid communication with the outer channel through the tunnel, and cause the block to clear the first opening to permit the first cosmetic liquid material to be in fluid communication with the inner channel through the first opening and the block and such that squeezing both the outer and the inner compartments will push both the first and the second cosmetic liquid materials to mix in the outlet assembly prior to dispensing out of the device; and whereby for closing the device after use, the individual secures the cap back onto the device to push both the outlet assembly and the valve assembly back to the inoperative position with the tunnel being blocked by the rear projection and the first opening being blocked by the block respectively.
