Abstract
A package for a multiple-component composition includes a first sheet and a second sheet connected to the first sheet, and at least one of the sheets is made of a flexible material. At least two storage chambers and a mixing chamber are located between the sheets and interconnected by passageways. In certain embodiments, the mixing chamber is located between the passageways. In some embodiments, the passageways are spaced from each other. Compressing the storage chamber directs components in the respective chambers into the mixing chamber for subsequent dispensing as needed. Optionally, an actuator is provided and has a channel for receiving the package. As the package moves through the channel, the storage chambers are compressed and the components in the storage chamber are directed to the mixing chamber.
