Abstract:
A food container is disclosed that is adapted for facilitating venting of gasses to and/or from the interior of a body of the food container. The food container includes a container body, a lid and a sealing membrane. At least one skip seal or gap is formed between the sealing membrane and the container body to facilitate venting. During formation of the at least one skip seal a recess in either the lid or rim of the container reduces pressure at the skip seal to reduce or eliminate inadvertent closing of the skip seal. Methods of manufacture of the food container are also disclosed.
