Patent ID: 7252091

Claim:
A hair colorant mixing and application apparatus containing: an end cap, a protrusion device, and a first solution housing, said protrusion device connected to said end cap and adapted for forcible engagement of a frangible membrane, said first solution housing being adapted to be connected to said end cap; said first solution housing defined between the distal end of said end cap and said frangible membrane, said first solution housing being open at both ends, said first solution housing being capable of retaining a hair coloring solution and being entirely made up of a collapsible bulbous tubular body, said collapsible bulbous tubular body designed to subside under forcible engagement; diaphragm means adapted to be connected to said first solution housing and containing a frangible membrane capable of being ruptured by said protrusion device; a second solution housing adapted to be connected to said diaphragm means; said second solution housing being capable of retaining a hair colorant; an applicator attached to said second tubular housing and distinct from said end cap, said applicator containing an application tip for applying a hair colorant mixture; wherein the collapsing of said first solution housing completely collapses said collapsible bulbous tubular body forcibly rupturing said frangible membrane using said protrusion device and simultaneously injecting the entire contents of said first solution housing into said second solution housing; and whereby pressure applied to said end cap subsides said collapsible bulbous tubular body forcing said protrusion device to rupture said frangible membrane allowing solutions in said first solution housing and said second solution housing to interact creating a mixture, which is applied through said applicator.
