Abstract
Abstract A package for sterilizing implements at a remote time and location is provided which package is formed of at least two compartments separated by a thin semi-permeable wall. The first compartment is provided to receive an implement to be sterilized therein with the second sealed compartment being provided with a substrate having a thermally-activated or releasable sterilizing gas bonded thereto. Upon release, the sterilizing gas permeates the thin semi-permeable wall to effect sterilization of the implement.
