CLOSURE FOR A PACKAGE FOR PRODUCTS TO BE STERILISED WITH A HIGH-TEMPERATURE STERILISING FLUID

摘要

The invention concerns a plastic package, having a content capable of being sterilised at high temperature, said package comprising at least a fluid communication member (16) between the inside and the outside of said package consisting of at least a frame circumscribing an opening and an inner seal (18) closing the opening, and whereof the peripheral edge (18a, 22a) is continuously linked to said frame, said inner seal including, a selectively sealing material sheet whereof the cutoff threshold from outside inwards, stops contaminating particles and allows through the thermal sterilising fluid, said selectively sealing material being deformable in the plane of said sheet at said high temperature. The invention is characterised in that it comprises means compensating the planar deformation of the selectively sealing material sheet, when said inner seal (18) is in contact with the thermal sterilising fluid, said compensating means being designed to release at least part of the load in the direction opening the fluid communication member (16) applied on the frame as a result of said deformation.
