A combination capsule adapted to both mix a plurality of ingredients to prepare them for use and then extrude the same through a nozzle attachable to one end of the capsule which comprises a pair of reciprocal sleeves respectively having compartments to contain different ingredients confined therein prior to the ingredients being brought into contact and the capusle being arranged to cause the ingredients to be brought together by pushing one sleeve into the other to rupture a membrane in the latter, whereby the ingredients may be agitated to mix them, followed by exchanging a cap on the outer end of the inner sleeve for an attachable nozzle and the outer end of the outer sleeve being closed by a closure having a flangible section adapted to be pushed into the sleeve and serve as a plunger to effect removal of the mixed ingredients through the nozzle.

A combination dental mixing and extrusion capsule including a pair of slidably telescoping sleeves, initially in partial telescopic relationship, the outer sleeve having a frangible diaphragm intermediately of its ends and a closure on one end having an integral frangible piston-like section and defining with said diaphragm a compartment for a first ingredient, the inner sleeve having a removable closure at the outer end defining with said frangible diaphragm of the outer sleeve another compartment for a second ingredient, the inner sleeve being movable telescopically inward to cause the inner end thereof to fracture the diaphragm and cause intermingling of the first and second ingredients to effect mixing thereof when the capsule is vibrated, and a nozzle optionally exchangeable for the removable closure on the inner sleeve to permit discharge of mixed material therethrough when said frangible piston-like section of the closure on the outer sleeve is severed by a plunger and is moved inward piston-like against the mixed material in the compartment of the inner sleeve, said frangible piston-like section having a diameter complementary to the inner diameter of said inner sleeve and also has a rim portion connected to the closure on the outer sleeve by a weakened integral configuration readily fractured when said piston-like section is engaged by an external plunger of a dispensing gun or the like and is moved against said piston-like section.
