Abstract
In various embodiments, a container lid with a castellated cork seal includes a plurality undulating u-shaped ridges that form peaks and troughs throughout a channel. The undulating u-shaped ridges throughout the channel may provide a surface for receiving a bottom of a separate container in a stacked configuration. In certain embodiments, when the lid is secured on top of a container, the u-shaped ridges protrude downwardly into the container for providing cantilevered support. In particular embodiments, the exemplary container lid includes detachable tear strips along a side wall of the container lid. Removing the tear strips allows access to one or more lift tabs for applying upward leverage to the exemplary container lid for removing the lid from a container.
