Abstract

A liquid dispensing hair removal device having a handle. A cartridge is pivotably mounted to the handle. The cartridge has a guard, a cap, and a blade between the guard and the cap. A dispensing unit is within the handle. The dispensing unit has a reservoir, a pump in liquid communication with the reservoir, and a resilient applicator in liquid communication with the pump. The applicator engages the cartridge and flexes as the cartridge pivots applying a biasing force against the cartridge.
