Abstract

A container, cartridge and method for holding, dispensing and mixing a fluid material comprised of at least two component fluids in an aseptic manner. A cartridge includes a cartridge body for holding one component fluid and having first and second ends. A seal is affixed to the first end of the cartridge body and a movable portion is sealed to the second end of the cartridge body. A movable member is fully disposed within the cartridge body and aseptically sealed between the first and second ends. The movable member may be moved in response to movement of the movable portion at the second end such that the movable member breaks the seal and the fluid material is thereby dispensed from the first end. This allows a fluid component, such as a concentrate, to be readily mixed with another fluid, such as water, under aseptic conditions and immediately contained within an aseptic environment of the container.
