Abstract: A liquid cosmetic applicator includes a housing unit, an applicator head connected to the housing unit, a reservoir unit, a switching unit, and a pressure unit. The reservoir unit is movable and includes a cartridge. The switching unit is connected to the housing unit and is operable for driving movement of the reservoir unit toward the applicator head. The pressure unit includes a stationary pressure base and a resilient member for biasing the reservoir unit away from the applicator head. The stationary pressure base is disposed between the reservoir unit and the applicator head, and has a pressure rod portion extending into the liquid chamber, and an outlet channel fluidly communicating with the liquid chamber and the applicator head.

Abstract: A tip unit of a cosmetic applicator includes a tube portion connected to a hollow body of the cosmetic applicator, and a tip portion tapering away to a point from the tube portion. The tip portion has a passage space contain liquid cosmetics advanced from the hollow body through the tube portion, and has a plurality of flexible blade segments, a plurality of guiding grooves defined respectively by corresponding adjacent pairs of the blade segments, and a plurality of slits, each communicating the passage space with a respective one of the guiding grooves, and being enlargeable when the tip portion is deformed so as to permit flow of the liquid cosmetics from the passage space to the respective one of the guiding grooves therethrough.
