Abstract
Abstract A closure is provided comprised of a thin flexible material for use on a needle disposal container so that a contaminated blood collection needle may be removed from its holder and deposited in the container without the user touching the needle or the needle hub. The device includes dual elongated tapered openings to accommodate varying diameters of needle hubs. By having dual openings, the useful life of the cap and its associated container is doubled. The cap of the invention is configured to be utilized with a large variety of collection containers of varying sizes and shapes. A feature of the invention includes chamfered surfaces at the enlarged end of each of the dual openings to provide a sharp edge which is useful for urging a needle hub out of its holder, without physically touching the needle or hub.
