Abstract: Telescoping leakproof two-piece medical syringe container. An upper tubular member or "cap" closed at its top end is wide enough along its vertical extent and downward to surround a syringe plunger, and also extends laterally from near its open lower end outward and downward to that end, so as to surround a finger grip of a syringe. A lower tubular member or "body" closed at its bottom end is wide enough along its vertical extent and upward to surround a syringe barrel with optional attached needle, and also extends laterally, from near its open upper end outward and upward to that end, so as to surround the syringe finger grip. The cap member and the body member telescope snugly together, and are retained against accidental opening by one or more detents on the open end of one of the tubular members overlapping the end of the other tubular member. At least one open end is tapered relative to the other open end to ensure that a leakproof container results when telescoped together.

Abstract: Medical syringe containment in a telescoping leakproof two-piece container for an individual medical syringe, especially as an inner container enclosing a radiopharmaceutical-filled syringe, and being enclosed in turn within a radiation-shielding outer container useful for shipment to a use location, where the respective containers are uncapped and the syringe is removed and used--whereupon the used syringe is re-inserted into the inner container before recapping, and the outer container is recapped about the recapped inner container and contents, for shipment to a disposal or reclamation site.

Abstract: Disposal of used medical syringes individually, with or without attached needles, is accomplished by placement in individual fluid leakproof containers and, if any residual radioactive content, also by placement of such container and contents within another container effective to shield the surroundings against radiation therefrom. The inner container is assembled from two tubular pieces, preferably by press-fitting them together into an audible and tactile snap-fit. The outer container is assembled from two larger tubular pieces, as by twist-fitting them together, thus enclosing the inner container, with the inner container enclosing a used syringe and any contents.
