  • Process for barrier coating of plastic objects
    Patent number: 5824198
    Abstract: A method for sequentially depositing a barrier composition film as a barrier on a substrate. The film is useful for providing an effective barrier against gas permeability in containers and for extending shelf-life of containers, especially plastic evacuated blood collection devices.
    Type: Grant
    Filed: June 24, 1994
    Date of Patent: October 20, 1998
    Assignee: Becton, Dickinson and Company
    Inventors: Joel L. Williams, Susan L. Burkett, Shel McGuire
  • Process for medical articles of syndiotactic polypropylene
    Patent number: 5720916
    Abstract: Syndiotactic polypropylene is blended with isotactic polypropylene and the blend melt processed into medical articles. The blends have molding cycle times which are up to 12 times shorter that for pure syndiotactic polypropylene.
    Type: Grant
    Filed: July 19, 1996
    Date of Patent: February 24, 1998
    Assignee: Becton, Dickinson and Company
    Inventors: Joel L. Williams, Yong-Jian Qiu, Shel McGuire
  • Process for barrier coating of plastic objects
    Patent number: 5616369
    Abstract: A method for sequentially depositing a silicon oxide based film as a barrier on a substrate. The film is useful for providing an effective barrier against gas permeability in containers and for extending shelf-life of containers, especially plastic evacuated blood collection devices.
    Type: Grant
    Filed: June 24, 1994
    Date of Patent: April 1, 1997
    Assignee: Becton, Dickinson and Company
    Inventors: Joel L. Williams, Susan L. Burkett, Shel McGuire
  • Molded tubular medical articles of blended syndiotactic and isotactic polypropylene
    Patent number: 5603696
    Abstract: Syndiotactic polypropylene is blended with isotactic polypropylene and the blend melt processed into medical articles. The blends have molding cycle times which are up to 12 times shorter that for pure syndiotactic polypropylene.
    Type: Grant
    Filed: January 5, 1995
    Date of Patent: February 18, 1997

  • Plastic articles of reduced gas transmission and method therefor
    Patent number: 5547723
    Abstract: An irradiated plastic article of reduced gas transmission has a coating of silicon oxide on a surface thereof. A method to reduce gas transmission through a plastic article includes depositing a coating of silicon oxide thereon and irradiating, either prior to or subsequent to depositing the silicon oxide.
