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.

La présente invention concerne un procédé destiné à accroître la résistance aux fuites dans un système fermé sous pression. Le procédé comporte les étapes consistant à mettre en place un système fermé comprenant un récipient qui est fermé par un opercule présentant une surface supérieure dotée d'une section exposée, et qui est maintenu sous une pression positive d'au moins environ 5 psi effectifs. Une surface de contact d'un composant dur est placée de façon souple au voisinage ou au contact d'au moins une partie d'une section frontalière et / ou d'une section centrale de la section exposée de l'opercule, afin de réduire la taille d'un éventuel renflement ou d'une déformation formée dans la section exposée de l'opercule. La présente invention concerne également un kit destiné à accroître la résistance aux fuites dans un système fermé sous pression, comprenant le composant dur.
