Abstract
Abstract A closure system for a conduit defining a connector at its end is provided having increased convenience of use and reliability of sterile sealing. A tubular closure member is provided which may be positioned about the connector in telescoping relation. The closure member surrounds but is spaced from the forward portion of the connector to provide space for antiseptic to be provided, to flow both inside of the connector member and about preferably at least 0.5 centimeter of the exterior forward portion thereof for improved antibacterial effect on the connector. An end closure such as a screw threaded cap may be provided.

Claim 7
Dependent Claim
50 words
The closure system of claim 4 in which said hollow, tubular handle member defines a front end which is proportioned to sealingly press against said second sealing face, while the tubular closure member defines an inner, annular seat proportioned to sealingly press against said first sealing face of the connector.
Claim 8
Dependent Claim
41 words
The closure system of claim 3 in which said hollow, tubular handle member and tubular closure member are joined together by said screw thread means in sealing relation with the connector and said end closure means is in sealingly closed position.
Claim 9
Dependent Claim
30 words
The closure system of claim 6 in which said end closure means comprises a separate cap member proportioned for removable sealing relation with the forward end of the tubular closure.
Claim 10
Dependent Claim
29 words
