<p>A pharmaceutical mixing container (2) includes telescoping outer and inner containers (4, 6). The inner container has a piston cap (28), to provide a piston-like seal between the inner and outer containers, and houses a piston (22) within its interior. The piston cap defines a flow path (32) between first and second variable volume regions (34, 36) within the inner and outer containers respectively. Reciprocating the inner container within the outer container causes the pharmaceutical (38) to pass through the flow path and between the variable volume regions and mix. A metering assembly (52) includes a metering stop (74), threadably positionable along the axis (25) of the mixing container, and a driver (70) secured to the inner container. The driver includes a drive stop (72) which engages the metering stop once the inner container has moved an appropriate distance towards its collapsed condition, typically during an injection.</p> |
