In order to minimize the amount of material required and yet attain the necessary stiffness and flexibility, the plate may be formed with a plurality of gussets 33 extending between the horizontal wall 31 and the approximately vertical portions of the plate. Similarl the edges of the upright portion may be thickened or ribbed to provide the ' necessary strength.

  • the actuator When the container is first placed in the autoclave, the actuator will be in the position shown in Figs. 1 and 10 holding the lid open and the expandable chamber 20 will be in the position shown in Figure 8. If the particular autoclave cycle being used includes one or more preliminary vacuum phases to withdraw air from the containers, no movement of the actuator will occur, since the port 48 and the valve for the inflatable chamber 20 are open and not covered by the sleeve 50. Any pressure changes within the autoclave will be automatically applied to the interior of the chamber as well. When a high temperature sterilizing fluid such as gas or steam is applied to the autoclave, the fluid flows into the interior of the container and through the open lid " into the interior of the basket through the ports 24, to displace the air and sterilize the container and the basket contents.

  • the sterilizing fluid will also effectively sterilize the lower surfaces of the lid and the surfaces of the gasket.
  • the sterilizing environment applied to the container will of course also enter the chamber 20 through the ports 48.

  • the high temperature, high pressure fluid is thus captured in the chamber. No change however occurs in the volume of the chamber during the remainder of the sterilizing phase, since temperature and pressure surrounding the chamber is essentially the same as that within it.
  • Most autoclaves have some minor variations in temperatures and pressures during the sterilizing phase but such variations are not significant enough to cause the actuator to perform its actuating function.
  • the lid of the container remains ' raised on one edge from the base such that fluid can flow freely into , and out of the container. It is important that the lid be raised sufficiently to permit the sterilizing fluid to circulate freely and displace the air in the container. Preferably the lid should be raised at least a third of the height of a dome-shaped lid. It is also important that the circulation holes 24 in the basket be sized and spaced to permit the sterilizing fluid to displace the air in the basket. Condensation drains from the basket 22 through the holes in the bottom, and from the container through the drain holes 26 in the container, base 14.
  • a vacuum is nevertheless formed within the container as the residual environment within the container cools and condenses, and as atmospheric pressure is introduced into the autoclave surrounding the container.
  • the pressure differential between the interior and the exterior of the container may be quite small for a period of time .in some situations such that it is important that a gasket prevent flow into the container at this time and the feathered edge of the gasket performs this function.
  • the pressure within the container should be temporarily greater than the pressure on the outside of the container, the gasket feathered edge will readily permit flow out of the container, thus acting like a one-way valve.
  • the lid As the pressure on the interior of the container drops relative to the exterior atmospheric pressure, the lid is drawn more tightly against the base thus compressing the gasket more. This causes the bead 16e of the gasket to be further compressed between the lid and the base, becoming the primary- seal for the container.
  • the container If the container is utilized in an autoclave providing a final vacuum phase, the residual environmen in the autoclave is quickly withdrawn and the residual environment within the container is likewise withdrawn past the feathered edge of the gasket.
  • the feathered edge of the gasket prevents flow into the container; and a quickly produced pressure differential between the interior and exterior of the container compresses the gasket greatly so that the bead 16e seals the container more tightly. Consequently, the container contents are sealed in essentially atmosphere free sterile environment, until the contents are to be used.

Abstract

Un recipient de stockage sterilise comprenant un couvercle de recipient (12) est maintenu ouvert par une plaque de support (18) sur laquelle est fixee une chambre (20) qui se dilate a un point predetermine pendant le cycle de sterilisation pour reagir contre le couvercle, de maniere a deplacer la plaque vers l'exterieur pour permettre au couvercle de tomber sur la base du recipient. Un joint (16) elastique empeche tout ecoulement de fluide dans le recipient apres que le couvercle est tombe, tout en permettant un ecoulement de fluide vers l'exterieur au travers du joint lorsque la pression interne depasse la pression externe. Lorsque le recipient doit etre ouvert, une soupape (60) de decompression permet d'eliminer l'effet du vide a l'interieur du recipient et de filtrer l'air penetrant dans le recipient a ce moment. De cette maniere, le recipient est ferme hermetiquement pendant la sterilisation de facon telle que les articles a l'interieur puissent etre stockes en conditions asceptiques. Ceux-ci empechent l'eventualite d'une recontamination des articles lorsqu'ils sont enleves de l'autoclave et stockes selon la pratique de l'art anterieur qui ne prevoit pas de recipient de stockage pouvant etre ferme hermetiquement pour les articles.
