Abstract

Packaging means, especially adapted for packaging a spool of tape and necessary resinforming reactant liquids for making a resin-type orthopedic cast, and for activating the initially separated liquids, applying the mixed liquids by centrifuge on to the tape, and extracting by centrifuge any excess liquid on the tape, all within the unopened package. Package comprises an outer container having a liquid-tight top closure; a container-like partition wall structure nested within and dividing the outer container interior into a lower, "mixing" region and an upper, "wetting and extraction" region; and an inverted cup-shaped rigid inner container within the mixing region for storing one reactant liquid separate from another placed at the bottom of the outer containers. A tape spool is mounted on the partition and within the upper region, and the partition is conical-shaped to funnel the mixed liquid from the mixing region into a hollow core region of the tape spool. A closed upper end of the inner container is press-fit from the underside into the partition wall opening, and a downwardly face open end of the inner container is closed by a valve. A valve stem projects upwardly through the…
