Abstract
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.
