ABSTRACT:
A pressure venting package for foods has a container with both top and side seal areas, and a closure which can accept two different types of insert disks, one for packaging oxygen sensitive (meat) products and the other for packaging non-oxygen sensitive (non-meat) products. The insert disk used for meat products has a gasket of low oxygen permeability and forms a seal with both the top and side seal areas of the container; whereas the insert disk used for non-meat food products forms only a top seal.
