Method for modifying the environment in a sealed container |
摘要 |
A method for controlling an apparatus for exchanging a first gas contained in a sealed container for a second gas while the container is in a chamber. The method comprises the steps of withdrawing the first gas from the container for a predetermined period of time and approximating the head space volume of the container based directly or indirectly upon a change in headspace pressure in the container. The method further includes the step of withdrawing the first gas from the container and air from the chamber under conditions which are dependent upon the approximation of the headspace volume and which reduce the damage to the container due to pressure forces.
