ABSTRACT:
A method for providing a container with a controlled environment utilizes a first flow method for applying a first source of environment to the interior of the container, a second flow method for applying a second source of environment to the container, and methods for controlling application of the individual sources of environment such that the first and second sources of environment are applied simultaneously for at least some period of time. The method for providing a container with a controlled environment is useful, for example, in food packaging applications whereby oxygen is removed from the food containers and replaced with a substantially inert environment prior to sealing the containers. In a preferred method, a rotary drum-type apparatus is employed for exposing containers in a continuous sequence to the individual sources of controlled environment.
