Abstract
To modify the headspace in a container to remove vacuum pressure, a container has a seal or cap which may provide a temporary opening into the container which is sealable under compression to provide a controlled raising of the internal pressure as the heated contents of the container cools. A sealing chamber () may enable the introduction of a fluid into the headspace () to force the fluid level () lower. Other methods and apparatus are described.
