  • Patent number: 6652509
    Abstract: A housing that can be used to form and maintain a fluid-tight connection between a container and a medical device. The housing comprises an internal receiving surface circumscribing a cavity into which a fitting of the medical device can be inserted. The internal receiving surface comprises a first wall portion having a first contact annulus and a second wall portion having a second contact annulus. Upon insertion of the fitting into an opening in the cavity of the housing, the fitting forms a primary seal with the first contact annulus and a secondary seal with the second contact annulus. The primary seal is formed as the surface of the fitting contacts the first contact annulus of the internal receiving surface of the housing. The secondary seal is formed as the surface of the fitting contacts the second contact annulus of the internal receiving surface of the housing.
