An amalgam capsule includes two chambers separated by a piston detachably formed as a part of the capsule end cover. One compartment is formed in part by a resilient flange portion of the capsule which is deformable to provide communication of the chambers and to permit a mixing of the contents of the chambers in the larger of the chambers. Delivery of the mixed amalgam is accomplished by removing a cap from one end of the capsule to expose an aperture therein, and connecting the opposite cover end of the capsule to a syringe, the plunger of which detaches the piston from the capsule cover and drives the piston through the mixing chamber to eject the amalgam therefrom.

A capsule for the storage of components and the mixing and delivery of dental amalgams or similar high viscosity mixtures comprising a hollow cylindrical body, an aperture in one end of said body, a demountable cap on said end of said body adapted to cover said aperture, an annular resilient flange

A capsule for the storage of components and the mixing and delivery of dental amalgams or similar high viscosity mixtures comprising a hollow cylindrical body, an aperture in one end of said body, a demountable cap on said end of said body adapted to cover said aperture, an annular resilient flange extending outwardly from the other end of said body, a cover cooperatively engaged with said flange and including a separable piston as a portion thereof disposed to close said other end of said body, the closure of said cylindrical body by said cap at one end and said cover piston portion at the other end forming therewithin a first chamber for storage of a first amalgam constituent, the configuration of said flange and said cover forming a second chamber therebetween for storage of a second amalgam constituent, said flange being elastically deformable to permit the displacement of said body away from said cover piston portion to provide communication between said first and second chambers and combine the amalgam constituents in said first chamber for mixing therein, means for connecting said capsule to a syringe, said piston portion of said cover being detachable from said cover by actuation of a connected syringe and displaceable thereby axially along said first chamber to displace the mixed amalgam therein through said aperture upon removal of said cap.
