A device for forming an orthopedic cast is disclosed which is composed of a core having a fibrous, porous tape rolled thereabout. The tape is impregnated with a first liquid component of a two-component hardenable system. The core is composed of a pressure rupturable container having the second component of the two-component system therein in liquid form. The entirety is encased in a flexible package which serves as a mixing chamber for intermixing the first and second components upon application of pressure to the package sufficient to rupture the core. After intermixing, the package is opened, the tape unrolled and placed about the broken limb in the conventional manner. The cast hardens within a short time at ambient temperature to provide a light-weight, breathable and waterproof orthopedic cast.

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 inner container and the package top closure to be pressed downwardly from the package exterior to move the inner container downwardly to open a liquid passage between the upper and lower regions of the outer container, and thereafter open the inner container valve. Fixed mixing paddles ar disposed along the interior bottom periphery of the outer container.
