Abstract
A stackable cover member for a container is provided which includes a countersunk central lid portion and a circumferential peripheral edge portion surrounding the lid portion. The edge portion of the cover member includes a flexible peripheral collar member, which is adapted to be sealed to the external sidewall of a container, and also includes an internal edge to be disposed internally within the container and which is integrally formed with the collar member. A groove is formed in the peripheral edge portion between the collar member and the internal edge for receiving an end edge of the container to which the cover member is to be sealed to. The internal edge has a transverse thickness greater than the collar member and forms the circumferential stacking edge of the cover member.
