Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
170 words
A disposable hypodermic syringe comprising in combination: a tubular housing which is open at one end and closed at the other, a hypodermic needle secured to the closed end of said housing, a piston slidably movable within the interior of said tubular housing for forcing a liquid therefrom through said hypodermic needle, a protective plastic closure of elongated tubular shape open at one end and closed at the other, said closure adapted to surround said hypodermic needle and to be frictionally engaged within the end of the tubular housing supporting said needle to provide protection for said needle during storage of the syringe, said closure having a thin wall portion containing a tubular extension thereof defining a passageway for receiving said needle, and a penetrable wall extending across said tubular extension through which penetrable wall said needle may be passed after penetrating same so as to permit said needle to be frictionally held within said tubular extension and to be retained therein after the syringe and needle have been used.
Claim 2
Dependent Claim
170 words
A disposable hypodermic syringe comprising in combination: a tubular housing which is open at one end and closed at the other, a hypodermic needle secured to the closed end of said housing, a piston slidably movable within the interior of said tubular housing for forcing a liquid therefrom through said hypodermic needle, a protective plastic closure of elongated tubular shape open at one end and closed at the other, said closure adapted to surround said hypodermic needle and to be frictionally engaged within the end of the tubular housing supporting said needle to provide protection for said needle during storage of the syringe, said closure having a thin wall portion containing a tubular extension thereof defining a passageway for receiving said needle, and a penetrable wall extending across said tubular extension through which penetrable wall said needle may be passed after penetrating same so as to permit said needle to be frictionally held within said tubular extension and to be retained therein after the syringe and needle have been used.
Claim 3
Dependent Claim
20 words
A hypodermic syringe in accordance with claim 1 wherein said tubular extension is formed in the end of said closure.
Claim 4
Dependent Claim
62 words
A hypodermic syringe in accordance with claim 2 wherein said penetrable wall of said tubular extrusion is operable to frictionally hold said needle to permit said needle to be broken adjacent where it is secured to said syringe while so held and to permit the broken portion of the needle to be retained within said tubular extension by said thin wall portion.
Claim 5
Dependent Claim
43 words
A hypodermic syringe in accordance with claim 3 wherein the hypodermic needle is weakened in the area where it is secured to the body of the syringe permitting it to be broken while retained by said penetrable wall portion within said tubular extension.
Claim 6
Dependent Claim
27 words
A hypodermic syringe in accordance with claim 1 wherein said tubular extension is formed with a circumscribing side wall which protrudes into the interior of the closure.
Claim 7
Dependent Claim
28 words
A hypodermic syringe in accordance with claim 1 wherein said tubular extension is formed with a side wall which extends exterior of the main wall of said closure.
