A compartmentalized dental amalgam mixing capsule including an upstanding elongated receptacle having a cylindrical interior chamber for receipt of an alloy therein. The receptacle is formed with an annular flange in the upper portion of the chamber including a central opening and formed with at least one lock pin projecting laterally outwardly from the receptacle. A rupturable pillow containing mercury therein is configured to overlie the flange. An elongated cylindrical cap formed with a closed top end, an open bottom end, and includes a piston device carried from the top end projecting axially downwardly therefrom to terminate in a hammer end configured to overlie the pillow. The cap is further formed with an elongated groove slidably receiving the lock pin and angling axially upwardly in one circumferential direction. The cap is telescopically received over the open end of the receptacle so that rotation of the cap in the direction opposite the one direction will draw the cap axially from a first position to a second position. As the cap is rotated, it is shifted from the first to the second position to drive the hammer end thereof downwardly toward the flange a distance sufficient to rupture the pillow and introduce the mercury through the central opening in the flange into the chamber for mixing with the alloy.

A compartmentalized dental amalgam mixing capsule comprising: an upstanding elongated receptacle having a cylindrical interior chamber for receipt of an alloy therein and formed with a closed bottom end and an open top end and at least one lock pin projecting laterally outwardly from said outer wall; an annular flange in the upper portion of said chamber and formed with a central communication opening; a rupturable pillow of a predetermined length on said flange and containing mercury therein; an elongated cylindrical cap formed with a closed top end and an open bottom end to be telescopically received over said open top end of said receptacle and formed with an elongated groove slidably receiving said lock pin and angling axially upwardly in one circumferential direction so that rotation of said cap in the direction opposite said one direction will draw said cap axially from a first position to a second position, said cap including a piston device carried from said top end and projecting axially downwardly therefrom to terminate in a hammer end to, when said cap is in said first position, overlie said pillow and as said cap is rotated to be shifted from said first to said second position, drive said hammer end downward toward said flange a distance sufficient to rupture said pillow. A compartmentalized dental amalgam mixing capsule comprising: an elongated receptacle formed with a peripheral wall defining a cylindrical interior chamber for receipt of an alloy therein and formed with a closed bottom end, an open top end and at least one lock pin projecting laterally outwardly from said wall; an indicator disposed on said outer wall; an interior annular flange in the upper portion of said chamber and formed with a central opening; a rupturable pillow of a predetermined axial length on said flange and containing mercury therein; an elongated cylindrical cap formed with a closed top end and an open bottom end to be telescopically received over said open top end of said receptacle and axially movable from a first position to a second position, said cap being formed with a window configured to be aligned with said indicator for visual indication of said indicator therethrough, and said cap further including a piston device connected to said top end and projecting axially downwardly therefrom to terminate in a hammer end to, when said cap is in said first position, overlie said pillow, and as said cap is shifted from said first to said second position, drive said hammer surface downward toward said flange a distance sufficient to rupture said pillow and to displace said indicator relative said window to indicate said second position.
