Dispenser and process

摘要

A dispenser ( 10 ) for dispensing a mixture ( 6 ) of a first flowable material ( 4 ) and a second flowable material ( 5 ) has a container ( 12 ) having a first chamber ( 20 ) and a second chamber ( 30 ). The first chamber ( 20 ) is adapted to contain the first material ( 4 ) and the second chamber ( 30 ) is adapted to contain the second material ( 5 ). The dispenser ( 10 ) further comprises a first membrane ( 50 a) separating the first and second chambers ( 20,30 ), and a second membrane ( 50 b) connected to the container ( 12 ) proximate the second chamber ( 30 ). Pressure applied to the first membrane ( 50 a) fractures the first membrane ( 50 a) wherein the first flowable material ( 4 ) and the second flowable material ( 5 ) mix to form a mixture ( 6 ). Pressure applied to the second membrane ( 50 b) fractures the second membrane ( 50 b) to dispense the mixture ( 6 ).
