ABSTRACT:
A mixing bag and method is provided for mixing ingredients and dispensing the mixed ingredients. The bottom of the bag has a converging tip. The top edge of the bag defines an open end and includes a reciprocally shaped edge to the bottom edge so that the bags can be cut from a continuous tube of material. The bag is filled with ingredients to be mixed through the open end and the ingredients are mixed by kneading the bag with the hands. The bag is closed prior to mixing. Once the ingredients are sufficiently mixed, the converging tip of the bag is removed and the contents are squeezed out from the bag. Prior to mixing, a closure device, or a twist applied to the bag, closes off the open end of the bag. Particular materials to be mixed are dental alginates and stones for making dental impressions. Other ingredients besides dental products can be mixed in the bag.
