Abstract: The Needle Capper is a single-cased 4 unit which houses used syringes 9/hypodermic needles 10. The Needle Capper is comprised of two plastic half-tubes 4 fitting around the syringe 9/hypodermic needle 10, hinged together at the bottom ends. A rubber cork 2 is located at the top of the hinge. The tip of the used needle 10 is inserted or depressed into the cork 2, causing the hinge of the two halves to raise and join together, thereby closing the case 4. When the case is closed, the connector button clasps male 6 and female 7, located on the handles join. The user then snaps the handles together, thereby locking the case. The needle is sealed inside the case and ready for proper disposal.
