Abstract
The current invention provides a container, a lid, a combination of the two, and a method of using the same. The container has a base and a sidewall extending upward from the base forming a continuous sidewall around the base. The upper portion of the sidewall has a rim and a skirt around the perimeter. The skirt has a removable tear tab to allow access to a lid for removing the lid from the container. The lid also has vents for air to exit the container, thereby preventing rising of the lid in low pressure areas. The vents further prevent entry of air into the container when the sealed container is taken to areas of higher pressure. A method of filling the container leaving an air gap between the product and the lid and utilizing the aforementioned vents is also provided.
