Abstract: A cosmetic applicator includes a casing, a cartridge disposed in the casing, a sleeve coupled to the casing, and a core. The cartridge includes a tube member formed with at least one protrusion, and a plug member having a shoulder section abutting against the tube member, a rear end section abutting airtightly against the protrusion, and a front end section. The sleeve has a rear end portion sleeved on the front end section and abutting against the shoulder section of the plug member, and at least one protrusion abutting airtightly against the front end section. The core has an absorbing segment extending through the sleeve and the plug member for absorbing liquid cosmetic, and a liquid output segment extending out of the sleeve.

Abstract: A cosmetic applicator includes a head, a tube including a tube body, multiple driving teeth, a rotating sleeve disposed in the head, multiple driven teeth arranged alternately with the driving teeth, and a threaded rod threadedly connected to the rotating sleeve. Each driving tooth has driving and retarding surfaces. An angle formed between the driving surface and the tube body is smaller than that formed between the retarding surface and the tube body. Each driven tooth has driven and contact surfaces. An angle formed between the contact surface and the rotating sleeve is larger than that between the driven surface and the rotating sleeve and is different from that between the retarding surface and the tube body.

Abstract: A cosmetic applicator includes: a seat that has a ventilation channel extending through an outer surface; an adjusting member that is disposed in a sleeve and that has several adjusting plates, an axial hole, and a gap formed in the adjusting plates and communicating the hole with the ventilation channel; and a core that extends through the hole, absorbs liquid cosmetic from a cartridge and defines a communicating channel with the adjusting member. The ventilation channel, the gap and the communicating channel define an air passage. The cartridge, the core and a bristle member define a liquid passage. Air is introduced into the cartridge through the air passage after the liquid cosmetic flows out of the cartridge through the liquid passage.
