Abstract

A device for reconstituting beverages by injecting fluid such as hot or cold water into a container having a granulated, powder or liquid food or beverage concentrate material therein comprises an electroresponsive valve coupled to a fluid supply, a combination nozzle and punch coupled to the valve outlet with a flexible tube, electroresponsive means for advancing the punch to penetrate the container and means for supporting the container so there will be an angle between the flow path of the fluid discharged from the nozzle and the axis or walls of the container during filling. Electric control circuitry is provided for timing the valve, punch and nozzle operations and for issuing a measured quantity of fluid to the container. Containers adapted for being easily penetrated by the punch, for sanitary sealing and for being engaged in a self-supporting state during filling are also provided.
