Abstract
A closure for use with a container with pharmaceutically pure contents therein. The elastomeric closure has an elastomeric base and a continuous polyparaxylylene coating on the base. The coating ranges from about 0.5 microns to about 2.0 microns in thickness. The closure member has a coefficient of friction of less than 1.0 and is capable of substantially preventing metal extraction from said elastomers.
Claims6
An elastomeric stopper for use with a container with pharmaceutically pure contents therein comprising an elastomeric base and a continuous polyparaxylylene coating on said base to reduce the coefficient of friction of said stopper to less than 1.0 and substantially prevent metal ion extractions from said base, said coating ranging from about 0.5 microns to about 2.0 microns in thickness.
