ABSTRACT:
A protective closure for the needle of a hypodermic syringe, which closure is also operable to receive and retain such needle after it is removed from or broken off the end of the syringe. In one form, the retainer is in the form of a cylinder with a closed outer end and a neck adapted to frictionally fit against a portion of the end of the syringe to protect its needle during storage prior to use. The closed end of the closure contains a tubular formation protruding therein for receiving the needle of the syringe which penetrates the bottom wall of the tubular formation. Once the needle is removed or broken off the syringe, it is retained by friction within the closure so that it may be disposed of without posing a hazard. In another form, a narrow tubular formation is integrally molded at one side of the closure and contains a partition therein through which the needle of the syringe may be penetrated and retained thereby within the tubular formation for disposal without posing a hazard.
