Method for mixing and dispensing

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.
