Abstract
A lid is defined for removably attaching to a hollow container body. The container is contemplated to be of the type having an opening thereon defined by a projecting rim. A bead may be formed on the rim projecting transverse to the direction of the rim projection. The lid includes a body for covering at least a portion of the container opening and a skirt depending from the body portion. The skirt is formed to engage the rim to removably secure the lid on the opening. One or more set of ridges is formed on the inner surface of the skirt at defined locations. The ridges are positioned substantially transverse to the bead and frictionally engaging the bead for securing the lid on the container opening. One or more retention tabs may also be provided on the inside surface of the skirt for engaging the underside of the bead on the rim. The bead of the container rim may also include a corresponding number of set of rim ridges, wherein the skirt ridge sets are positioned at locations for engaging with the sets of rim ridges.
