Abstract
Apparatus for selectively mixing two components such as a powder and a liquid in a quick and efficient manner. The apparatus includes a compressible chamber with a liquid component therein, the compressible chamber including gas-trapping and reservoir compartments in open communication. Included is an arrangement to access the gas-trapping compartment such that the chamber may be connected to a container having a mixing component such as a powder therein so as to form a selectively opened pathway between the container and the compressible chamber of the apparatus. The apparatus may include the container. After the pathway is opened, the gas-trapping and reservoir compartments are selectively positioned to facilitate proper mixing of the liquid component in the chamber with the component in the container. Also disclosed is a manipulation for separately storing and selectively mixing two components in the apparatus including the container, the manipulation including pathway opening, liquid transfer, liquid exchange and liquid emptying from the container into the chamber.
