Abstract

A hand-held colloidal solution applicator particularly suited for applying relatively viscous solutions such as gels and pastes to the hair comprises a generally cylindrical rigid container for receiving the hair treating solution and has opposed externally threaded ends. A comb-like applicator nozzle is threadedly received on one end of the container for properly placing and distributing the solution and a non-dispensing hair-parting wand having a cap portion is threadedly received on the other end of the container opposite the applicator end and has a central opening through the cap portion end wall. The hair-parting wand extends outwardly from the cap portion end wall parallel to the longitudinal axis of the container and is laterally offset from the central opening. A dispensing plunger has a shaft portion extending slidably through the central opening with a piston at one end disposed within the container and the outwardly extending end of the shaft portion receives the thumb of the operator for sliding the piston within the container to force the solution through the applicator nozzle. The thumb operated piston feature reduces hand fatigue of the operator while giving more pr…
