Title (EN) STERILIZED STORAGE CONTAINER AND METHOD
(FR) BOITE D"EMMAGASINAGE STERILE ET PROCEDE D"UTILISATION
Abstract:
(EN) The invention pertains to the steam sterilization of objects (100) in a container (10) which serves as the storage container for the sterilized objects until the latter are ready for use. The container (10) automatically seals itself during the sterilization cycle and before removal from the sterilizer so that the container contents are maintained in an aseptic environment without danger of recontamination during storage. In the Figures 1-13 embodiments, a valve opening (36) permits steam to circulate into a container (10) and permits condensation to drain from the container while the valve (52) is open. Steam within an expandable chamber (66), (166), captured through the closing of a temperature responsive valve (92, 192), causes the chamber to expand when pressure drops at the end of a sterilizing cycle, and closes the valve (52). A lid (12) and gasket (16) permit steam to be withdrawn from the container but prevent air flow into the container. In the Figures 14-16 embodiments, container bottom wall (314) is sloped so that condensation will flow to the edges. A lid (312) is held partially open by an actuator pin (344) connected to an expandable chamber (342). Steam captured through valve (352, 354) expands in response to the pressure drop at the end of the sterilizing cycle to expand the chamber to withdraw the pin and allow the lid to close. In the Figures 17-22 embodiments, an expandable chamber (440) moves a lever mechanism (422) to seal a container at a predetermined pressure after a final vacuum in a sterilizing cycle but before the container is removed from the sterilizer.
(FR) L"invention concerne la sterilisation a la va peur d"objets (100) places dans une boite (10) qu sert de boite d"emmagasinage des objets sterilise jusqu"a que ces derniers soient prets a etre utilises. La boite se ferme hermetiquement et automatiquement d"elle-meme pendant le cycle de sterilisation et avant qu"elle ne soit retiree du sterilisateur de sorte que le contenu de la boite soit maintenu dans une atmosphere aseptique sans danger de recontamination pendant l"emmagasinage. Dans les formes d"execution illustrees aux figures 1 a 13, une ouverture de clapet (36) permet a la vapeur de circuler dans une boite (10) et permet a la condensation de s"echapper de la boite pendant que le clapet (52) est ouvert. De la vapeur a l"interieur d"une chambre expansible (66), (166), emprisonnee par la fermeture d"un clapet sensible a la temperature (92, 192), force la chambre a se dilater lorsque la pression tombe a la fin d"un cycle de sterilisation, et ferme le clapet (52). Un couvercle (12) et un joint (16) permettent a la vapeur d"etre extraite de la boite mais empechent l"air d"y penetrer. Dans les formes d"execution illustrees aux figures 14 a 16, le fond (314) de la boite est incline de maniere a ce que la condensation coule vers les bords. Un couvercle (312) est maintenu partiellement ouvert par un pointeau (344) relie a une chambre expansible (342). La vapeur emprisonnee par l"intermediaire du clapet (352, 354) se dilate a la suite de la chute de pression a la fin du cycle de sterilisation, ce qui agrandit la chambre et permet le retrait du pointeau et la fermeture du couvercle. Dans les formes d"execution illustrees aux figures 17 a 22, une chambre expansible (440) actionne un mecanisme de levier (422) pour fermer hermetiquement une boite a une pression predeterminee apres avoir fait le vide a la fin d"un cycle de sterilisation mais avant que la boite ne soit retiree du sterilisateur.
