Abstract

Abstract The cartridge, according to this invention, has a main container storing a first ingredient; an auxiliary container storing a second ingredient, and extending into the main container; a movable piston in the auxiliary container with a plunger secured thereto for exuding the second ingredient into the main container upon forward movement of the piston and plunger; a dasher threaded onto the inner end of the auxiliary container for intermixing the two ingredients upon manual movement of the auxiliary container relative to the main container after which rearward movement of the plunger pulls the piston rearwardly to return a portion of the mixture to the auxiliary container, with the auxiliary container then being removable from the main container; and has a nozzle securable to the auxiliary container for dispensing the mixture therefrom upon subsequent forward movement of the plunger and piston therein.
