IPC: A45D34/04
Filed: 2001-07-20
Abstract: A disc-type cosmetic applicator has a plurality of individual discs connected by integrally molded springs to yield a single disc array. The space between the individual discs of the disc array is compressible during withdrawal from a container so that excess product can be removed from the applicator by a wiper. After passage through the wiper, the springs between the individual discs are biased to return to the array to a fully expanded position. The compressing of the discs during withdrawal allows a controlled amount of product to remain on the applicator for application by the consumer, and the returning of the discs to their expanded position by the spring causes the discs to assume a configuration which allows the applicator to effectively comb and separate the eyelashes. The single unit construction of the multi-disc array allows efficient and convenient assembly of a complete applicator by securing a single disc array to a conventional applicator stem with a simple pin.
