Method for mixing and dispensing
First Claim
1. A method of sterilizing a chemical composition comprising the steps of:
- providing a first container with a first chemical composition and a second container with a second chemical composition, wherein the first container is positioned with respect to the second container so that the first chemical composition is maintained apart from said second chemical composition, but can be combined with the second chemical composition;
sealing the first and second containers in a first sealing layer to form a first sealed container enclosure;
enclosing said first sealed 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 first and second chemical compositions, said first and second containers, said first sealed container enclosure, and said closed shipping package.

Abstract
A method for sterilizing a concentrated composition and a diluent. The diluent is contained in a large container, and the concentrated composition is contained in a small container that is positioned within the large container. The combined containers are placed in at least one sealing layer that is hermetically sealed, and is also preferably placed in a second sealing layer that is also hermetically sealed. The bagged container is then placed in a carton, which preferably has a liner, and the carton is closed. The carton is then irradiation sterilized. The carton is delivered to the clean room. At a first staging area, the carton is opened and the bagged container is removed and brought to a second staging area. At the second staging area, the second sealing layer is removed and the container can be stored in the first sealing layer. The container is brought into the clean environment, where the first sealing layer is removed. At that point, the small container is opened and the chemical composition is released into the large container, so that the chemical composition mixes with the diluent. The container can then be shaken until the chemical composition is thoroughly mixed with the diluent.

9. A method of storing a first and second chemical composition for use in a sterile environment, said first and second chemical compositions being respectively contained in a first and second container, said first and second containers being hermetically sealed in successive first and second hermetically sealed container enclosures, and a shipping enclosure to form a closed shipping package adapted to be transported, comprising the steps of:
-
removing the first and second containers and the first and second hermetically sealed container enclosures from the shipping enclosure of the closed shipping package;
transporting the first and second containers and the first and second hermetically sealed container enclosures to the storage area;
storing the first and second containers 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 first and second containers contained in the first hermetically sealed container enclosure to the sterile environment for use;
removing the first hermetically sealed container enclosure in the sterile environment for use of the first and second chemical compositions in the sterile environment; and
,releasing the first chemical composition from the first container into the second container to mix with the second chemical compositions in the sterile environment. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method of sterilizing a chemical composition comprising the steps of:
-
providing a container having a first compartment for retaining a first chemical composition and a second compartment for retaining a second chemical composition, wherein the first compartment is positioned with respect to the second compartment so that the first chemical composition is maintained apart from said second chemical composition, but can be combined with the second chemical composition;
sealing the container in a first sealing layer to form a first sealed container enclosure;
enclosing said first sealed 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 first and second chemical compositions, said container, and said first sealed container enclosure. - View Dependent Claims (17, 18, 19, 20, 21)

22. A method of mixing a first and second composition in a sterile environment comprising:
-
placing said first and second chemical compositions in a respective first and second compartment;
hermetically sealing said first and second compartments in a sealing layer to form a hermetically sealed container enclosure;
irradiating the hermetically sealed container enclosure to simultaneously sterilize said first and second chemical compositions, said first and second compartments, and said hermetically sealed container enclosure to form a sterilized hermetically sealed container enclosure;
introducing the sterilized hermetically sealed container enclosure into the sterile environment;
releasing the first chemical composition from the first compartment into the second compartment, so that the first chemical composition mixes with the second chemical composition.
