ABSTRACT:
A prefilled, two-constituent system is provided with first and second containers. The first container includes a first chamber having a dispensing end. The dispensing end defines a dispensing passage communicating through the dispensing end to accommodate the dispensing of fluid from the first chamber. A movable seal is slidably disposed in the first chamber, and a first constituent is provided in the first chamber between the dispensing end and the seal. A second container includes a barrel that is sized to be disposed in the first container and that has a discharge end defining a discharge passage communicating through the discharge end to accommodate the discharge of fluid from the barrel. A plunger is slidably disposed within the barrel. A liquid second constituent is provided in the barrel between the discharge end and the plunger. The first container seal and the second container barrel discharge ends are engageable to cooperatively define a coupling accommodating the flow of the liquid second constituent from the second container barrel into the first chamber of the first container as the barrel moves outwardly relative to the first chamber.
