  • Patent number: 5230426
    Abstract: A hypodermic needle disposal system includes a housing forming an array of parallel cells, each to receive a tube containing a bonding resin. Each tube includes a rupture seal on its front end. A used needle is directed into a tube to pierce its rupture seal and embed itself in resin. When the resin bonds on the needle, the needle and tube are together removed from the cell for disposal. Tubes are restrained from free movement and from sliding out of their cells by a gravity locking engagement with the housing.
