Abstract
A dental capsule that requires a capsule body defining a reservoir that is loaded with predetermined amounts of one or more materials to be mixed, sealed by a removable plug having flexible gripping flange fingers extending laterally relative to the axis of the capsule to facilitate the removal of the plug. Subsequent to the mixing of the materials within the capsule by amalgamation, the capsule is placed in a suitable ejector or syringe whereby the mixed materials can be readily extruded therefrom and directly placed in or about a prepared tooth whereby the flexible gripping flange fingers function as a base for storing the capsule in a vertical position and which flexible fingers are capable of being deflected so as to be pushed through the capsule as the plug is displaced to extrude the mixed material.
