Abstract
The present invention relates to a method for increasing leakage resistance in a closed, pressurized system. The method involves providing a closed system including a container sealed with a septum having a top surface with an exposed section, which is maintained under a positive pressure of at least about 5 psig. A contact surface of a hard component is fixedly placed adjacent to or in contact with at least a portion of a border section or a central section of the exposed section of the septum, or both, to reduce the size of any bulge or deformation formed in the exposed section of the septum. The present invention also relates to a kit for increasing leakage resistance in a closed, pressurized system, which includes the hard component.
