  • Pharmaceutical elastomeric coating
    Patent number: 5000994
    Abstract: An elastomeric member for use with a container and in contact with pharmaceutically pure contents therein. The elastomeric member has an elastomeric base and a continuous polyparaxylylene coating on the base. The coating ranges from about 0.1 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.
    Type: Grant
    Filed: January 30, 1989
    Date of Patent: March 19, 1991
    Assignee: The West Company, Incorporated
    Inventors: Val G. Romberg, Patty H. Kiang, Wayne T. Curry
  • Pharmaceutical elastomeric coating
    Patent number: 4973504
    Abstract: An elastomeric member for use with a container and in contact with pharmaceutically pure contents therein. The elastomeric member 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.
    Type: Grant
    Filed: November 7, 1988
    Date of Patent: November 27, 1990
    Assignee: The West Company Incorporated
    Inventors: Val G. Romberg, Patty H. Kiang, Wayne T. Curry
  • Glass container
    Patent number: 4882210
    Abstract: A container for use with a closure and a glass container having an access opening for a closure. The container was a crush strength increasing polyparaxylylene coating on at least one side of the glass container at a thickness of at least 0.1 microns to give at least 40% increased crush strength.

  • Pharmaceutical elastomeric coating
    Patent number: 4808453
    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.
    Type: Grant
    Filed: April 13, 1987
    Date of Patent: February 28, 1989
