  • Patent number: 5730729
    Abstract: An article of manufacture adapted to be connected to a male thread comprises an exterior surface, a cavity opening away from the exterior surface and defining an interior surface, and a plurality of ribs disposed on the interior surface extending longitudinally away from the exterior surface. The article can be connected to the male thread by threading the cavity onto the male thread. It is a particular advantage that the article of this invention, unlike prior art female threaded articles, can be prepared by conventional simple injection molding techniques not requiring an unscrewing step. In one preferred embodiment, the article is a plunger rod intended to be connected to the male threaded post of a plunger of an associated cartridge-needle unit to form a syringe assembly.
