First Claim
1. A hair colorant mixing and dispensing apparatus, comprising a first segment, a second segment, and a third segment;
- said first segment comprising;
a tubular housing, a rear end surface, and a front end surface, said tubular housing and said front end surface being adapted for forcible engagement with said second segment;
a first reservoir defined between said rear end surface and said front end surface within said tubular housing for containing a first volume of liquid; and
a first rupturing means disposed within said first reservoir;
said front end surface being rupturable by said rupturing means when said first and second segments are forcibly engaged;
said second segment comprising;
a tubular housing, a rear end surface, and a front end surface, said tubular housing and said rear end surface being adapted for forcible endwise engagement with said first segment, said tubular housing and said front end surface being adapted for forcible engagement with said third segment;
a second reservoir defined between said rear end surface and said front end surface within said tubular housing for containing a second volume of liquid;
said rear end surface being rupturable by said rupturing means of said first segment when said first and second segments are forcibly engaged;
said third segment comprising;
a tubular housing;
a rear end adapted for forcible endwise engagement with said front end of said second segment and further defining a second rupturing means; and
a front end defining an applicator, whereby forcible engagement of said first and second segments allows said first and second reservoirs to communicate, and forcible engagement of said second and third segments allows said second reservoir to communicate with said applicator.

Abstract
A disposable, solution-mixing hair colorant dispenser: tubular rear segment including first reservoir having rupturable front end; tubular middle segment including second reservoir having rupturable rear and front ends; tubular front segment including rear end and forward-projecting porous applicator. Rupturing member near adjacent ends of first and second reservoirs for rupturing both when first and second segments are engaged. Rupturing member near front end of second reservoir for rupturing same when second and third segments are engaged. Alternative rupturing members: double-ended between first and second reservoirs and single-ended attached to third segment; double-ended within second reservoir; single-ended within first reservoir and single-ended attached to third segment. Segments threaded for endwise engagement to seal segments and rupture reservoirs. Fluids mixed and dispensed through applicator.

11. A hair colorant mixing and dispensing apparatus, comprising endwise serially sealingly engageable first, second and third tubular segments, a first rupturing means disposed between said first and second segments, and a second rupturing means disposed between said second and third segments;
-
said first segment defining an interior including a first reservoir;
said second segment defining an interior including a second reservoir;
said third segment defining an interior including an applicator communicating with said interior;
said first rupturing means comprising at least one stabilizing member for securing said first rupturing means to an end of at least one of said first and second segments;
said first rupturing means comprising at least one cutting edge fixed to said at least one stabilizing member and disposed toward at least one of said respective ends of said first and second segments;
said first rupturing means comprising at least one thrusting member contacting said at least one cutting edge;
said first and second segments when so engaged defining a range of relative longitudinal displacement including first and second relative positions;
engagement in said first position, said second position, and all intermediate positions forming a seal between adjacent ends of said segments to prevent fluid leakage therefrom;
engagement in said second position resulting in the transmission of force through said at least one thrusting member thereby rupturing adjacent ends of said segments and holding said ruptured ends open for facilitating the passage of fluid;
said second rupturing means comprising at least one stabilizing member for securing said second rupturing means to an end of at least one of said second and third segments;
said second rupturing means comprising at least one cutting edge fixed to said at least one stabilizing member and disposed toward said end of said second segment;
said second rupturing means comprising at least one thrusting member contacting said at least one cutting edge;
said second and third segments when so engaged defining a range of relative longitudinal displacement including first and second relative positions;
engagement in said first position, said second position, and all intermediate positions forming a seal between adjacent ends of said segments to prevent fluid leakage therefrom;
engagement in said second position resulting in the transmission of force through said at least one thrusting member thereby rupturing an end of said second segment and holding said ruptured end open;
whereby engagement of said first, second, and third segments in said second relative positions allows said first and second reservoirs and said applicator to communicate. - View Dependent Claims (12, 13, 14, 15, 16, 17)
