Claim:
1. An infusion assembly, comprising: a first infusion body having an end wall; a first nozzle operably engaged with the first infusion body proximate to the end wall; a first plunger configured to translate longitudinally within the first infusion body for dispensing a first substance out of the first infusion body through the first nozzle, the first plunger comprising a translating member and a stopper piston separable and removable from the translating member, the stopper piston defining a cavity and being configured to facilitate a two-stage seating arrangement; a second infusion body configured to be received within the first infusion body; a second nozzle operably engaged with the second infusion body; a second plunger configured to translate longitudinally within the second infusion body for dispensing a second substance out of the second infusion body through the second nozzle; and wherein the stopper piston, once separated from the translating member, is configured to receive the second nozzle in a first seating position within the cavity such that the second plunger is capable of advancing the stopper piston to dispense the first substance from the first infusion body, and the second plunger is capable of being further advanced to cause the stopper piston to abut the end wall and to move the second nozzle into a second seating position within the cavity so as to extend the second nozzle through the stopper piston such that the second substance contained in the second infusion body is capable of being dispensed through the second nozzle and the first nozzle.
