Abstract: A device for and a method of mixing and dispensing alginate is disclosed. The invention entails a pouch having a sealable aperture through which alginate and water may be added. The pouch also has an sealable spout. The function of these two openings may be performed by a single opening. When the alginate and water are in the pouch, a dentist will mix the two together by manipulating the pouch with his hands. When the contents of the pouch are thoroughly mixed, the spout may be opened and the pouch evacuated. When the pouch is empty, it may be discarded.
