Abstract
A flexible, disposable ampule is pre-dosed with a first ingredient, and a second ingredient is introduced into the ampule immediately before a mixing operation. The ampule conveniently fits within a rigid capsule adapted for use with a dental amalgamator which, when activated, thoroughly mixes the ingredients within the ampule. After the ingredients are mixed and the preparation is formed, the ampule is removed from the capsule and the preparation is dispensed by establishing an outlet opening and compressing the ampule between the distal phalange segments of a thumb and a finger.
