Abstract
A sterilized chemical composition is stored in a sterile environment for a prolonged period of time, hermetically scaled in successive enclosures and a shipping enclosure. The third sealing layer is removed prior to entering a storage area. The second layer is removed prior to taking the container to the sterile environment. The storage area may also be sterile. The innermost container may be an aerosol container and the composition a disinfectant liquid such as alcohol. The entire shipping enclosure and contects is preferably sterilized with gamma radiation.
Claims18
A method of storing a sterilized chemical composition for use in a sterile environment and maintaining the sterilization shelf life of the sterilized chemical composition for a prolonged period of time in a storage area, said sterilized chemical composition being contained in a sealed container, said sealed container being hermetically sealed in successive first and second hermetically sealed container enclosures, a third sealing layer enclosure and a shipping enclosure to form a closed shipping package adapted to be transported, comprising the steps of:
- removing the third sealing layer enclosure from the shipping enclosure of the closed shipping package;
- transporting the sterilized chemical composition contained in the sealed container, the first and second hermetically sealed container enclosures and the third sealing layer enclosure to the storage area;
- removing the third sealing layer enclosure;
- storing the sealed container enclosed in the first and second hermetically sealed container enclosures in the storage area for a period of time;
- after the period of time, removing the second hermetically sealed container enclosure and transporting the sealed container contained in the first hermetically sealed container enclosure to the sterile environment for use;
- and
- removing the first hermetically sealed container enclosure in the sterile environment for use of the sterilized chemical composition in the sterile environment.
A method of sterilizing chemical composition contained in an aerosol container comprising the steps of:
- providing an aerosol container having an internal volume;
- charging the internal volume of the aerosol container with a quantity of chemical composition;
- pressurizing the internal volume of the aerosol container with an inert gas and sealing the aerosol container;
- hermetically sealing the aerosol container in a first sealing layer to form a first hermetically sealed container enclosure;
- hermetically sealing said first hermetically sealed container enclosure in a second sealing layer to form a second hermetically sealed container enclosure;
- inserting at least one second hermetically sealed container enclosure into a third sealing layer;
- closing said third sealing layer to enclose said at least one second hermetically sealed container enclosure and form a third container enclosure;
- enclosing said third container enclosure in a shipping container to form a closed shipping package;
- and
- externally irradiating said closed shipping package at a predetermined radiation level for a predetermined time interval to simultaneously sterilize said chemical composition, said aerosol container, said first and second hermetically sealed container enclosures and said third container enclosure.
A method of sterilizing a disinfecting liquid contained in an aerosol container comprising the steps of:
- providing an aerosol container having an internal volume;
- charging the internal volume of the aerosol container with a quantity of disinfecting liquid;
- pressurizing the internal volume of the aerosol container with an inert gas and sealing the aerosol container;
- sealing the aerosol container within a pluarlity of successively nested hermetic sealing layers to form a hermetically sealed container enclosure, said sealing step comprising the further steps of;
- hermetically sealing the aerosol container in a first sealing layer to form a first hermetically sealed container enclosure;
- hermetically sealing said first hermetically sealed container enclosure in a second sealing layer to form a second hermetically sealed container enclosure;
- inserting at least one second hermetically sealed container enclosure into a third sealing layer;
- and
- closing said third sealing layer to enclose said at least one second hermetically sealed container enclosure and form a third container enclosure;
- and
- externally irradiating said third container enclosure and said aerosol container therewithin at a predetermined radiation level for a predetermined time interval to simultaneously sterilize said disinfecting liquid, said aerosol container, and said plurality of successively nested hermetic sealing layers.
A method of storing a sterilized chemical composition and maintaining the sterilization shelf life of the sterilized chemical composition for a prolonged period of time in a sterile environment, said sterilized chemical composition being contained in a sealed container, said sealed container being hermetically sealed in successive first and second hermetically sealed container enclosures, a third scaling layer enclosure and a shipping enclosure to form a closed shipping package adapted to be transported, comprising the steps of:
- removing the third sealing layer enclosure from the shipping enclosure of the closed shipping package;
- storing the sealed container and successive first and second hermetically sealed container enclosures in the sterile environment for a period of time;
- after the period of time, removing the second hermetically sealed container and the first hermetically sealed container enclosure within the sterile environment for use of the sterilized chemical composition in the sterile environment.
A method of sterilizing a chemical composition contained in a sealed container comprising the steps of:
- providing a container having an internal volume;
- charging the internal volume of the container with a quantity of chemical composition;
- sealing the internal volume of the container to form a sealed container;
- hermetically heat sealing the container in a first single-layer sealing layer to form a first hermetically heat-sealed container enclosure;
- hermetically heat sealing said first hermetically sealed container enclosure in a second single-layer sealing layer to form a second hermetically heat-sealed container enclosure;
- enclosing at least one second hermetically heat-sealed container enclosure in a third single-layer sealing layer to form a third container enclosure;
- enclosing said third container enclosure in a shipping container to form a closed shipping package;
- and
- externally irradiating said closed shipping package at a predetermined radiation level for a predetermined time interval to simultaneously sterilize said chemical composition, said sealed container, said first and second hermetically heat-sealed container enclosures and said third container enclosure.
