Abstract
An apparatus and method for containing, mixing and dispensing multiple component products, wherein the components are maintained separate from one another until immediately prior to use, and the components are then mixed together to form a product for use. The apparatus includes a pressurized outer container for holding a primary component, and a pressurized inner container supported inside the outer container for holding a secondary component separate from the primary component. The inner container is openable when the pressure inside the inner container exceeds that in the outer container by a predetermined amount, whereby the interiors of the inner and outer containers are in communication with one another to enable admixture of the two components. In use, the primary component is introduced into the outer container and pressurized to a predetermined pressure. The secondary component is then introduced into the inner container and pressurized to a predetermined pressure less than the pressure in the outer container. When it is desired to admix the two components and dispense the resulting product, the outer container is inverted and part of the pressure therein released, until the pressure in the inner container exceeds that in the outer container by a predetermined amount, whereupon the inner container opens and the two components are admixed.
