The present invention relates to a lyophilization process and a cap (10) intended for vials or use therewith for containers that are subjected to lyophilization condi- tions where the cap (10), which may be resiliently helped in place or screwed on, includes a plug member (20) mov- able within a fluid passageway (23) in the cap, the plug member while positioned in the fluid passageway (23) is movable between a first upwardly extending venting po- sition and second downwardly engaging, sealing position whereby fluid from the vial or container is precluded from flowing through the fluid passageway (23) in the cap (10).

Ledit bouchon (10) qui peut être élastiquement mis en place ou vissé comporte une fiche (20) déplaçable dans un passage (23) pour fluide. Lorsqu'elle est placée dans le passage (23), ladite fiche est mobile entre une première position d'évacuation s'étendant vers le haut et une seconde position enfoncée vers le bas et d'étanchéité, position qui empêche du fluide présent dans le flacon ou récipient de s'écouler dans le passage (23) pour fluide ménagé dans le bouchon (10).
