HAIR COLOR APPLICATOR
An apparatus for applying a two-component liquid composition to a surface has a housing having an open end, and a roller ball disposed and rotatably retained in the housing and projecting through the open end. There are two containers disposed at least partially in the housing. Each container has a dispensing nozzle arranged adjacent the roller ball. The nozzles have an open end such that a liquid or pasty substance disposed in each of the containers flows from the containers through the nozzle directly to the roller ball upon application of pressure to the substances in the containers. Rolling roller ball across a surface mixes the two substances on the roller ball with each other. This occurs by virtue of the movement of the roller ball around the surface, which causes the substances to flow around the ball and mix with each other during rolling.
1 . An apparatus for applying a two-component liquid composition to a surface, comprising:
a housing having an open end, an inner surface and an outer surface;
a roller ball disposed and rotatably retained in the housing and projecting through the open end;
two containers disposed in the housing, each container having a dispensing nozzle arranged adjacent the roller ball;
wherein liquid or pasty substances disposed in each of the containers flow from the containers through the nozzle directly to the roller ball upon application of pressure to the substances in the containers, and wherein rolling the roller ball mixes the two substances on the roller ball with each other.
2 . The apparatus according to claim 1 , wherein the roller ball contains a plurality of grooves that are configured to direct the flow of substances from the containers into the grooves.
3 . The apparatus according to claim 2 , wherein the grooves are arranged in a criss-cross pattern.
4 . The apparatus according to claim 1 , further comprising a plunger connected to each of the compartments, such that pressing on the plunger pushes the substances out of the nozzles and onto the roller ball.
5 . The apparatus according to claim 1 , wherein the compartments are formed of a bendable material and wherein pressure is applied to the substances by squeezing the containers.
6 . The apparatus according to claim 5 , wherein the containers are encased in a single covering.
7 . The apparatus according to claim 1 , wherein the containers are removable from the housing.
8 . The apparatus according to claim 1 , wherein one of the containers contains hair color and the other one of the containers contains developer.
