Abstract
The present invention discloses a container comprising a circular end wall, a peripheral body wall, and an annular rolled end seam. A channel is created in the rolled end seam and is in communication with the interior of the container. A one-way valve forms a seal between the rolled end seam and an outer surface of the body wall. The one-way valve allows gases from the interior of the container to escape from the container during packaging.
