ABSTRACT:
A dual chamber dispenser is formed of a first chamber and a second chamber connected together by a one-way valve with the first chamber holding a flowable first component to be mixed at a time of use with a second component in the second chamber. The one-way valve permits flow from the first chamber into the second chamber but prevents any backflow from the second chamber to the first chamber. A metered dose outlet chamber is connected to the second chamber by way of another one-way valve, so that the mixed components can be directed into the outlet chamber but prevented from backflow into the second chamber. A dispensing head is connected to the outlet chamber for collapsing the outlet chamber and dispensing selected amounts of the mixed components. With the components in the first and second chambers kept in a separated condition the dispenser has a long shelf life though the mixed components have only a relatively short period of use after the mixing has been effected.
