- a lid stamped from aluminum, the lid being configured to include;
a top base terminating around a periphery at an edge;
a raised ridge extending around the periphery of the edge;
a skirt extending downwardly from the raised ridge and extending continuously around the top base to form a well there-between, the skirt having an internal surface facing the well and an external surface facing directly opposite of the internal surface and the well, and wherein the skirt has a lower edge that directly transitions into a rolled lip;
an angle between the raised ridge and the downwardly extending skirt is defined to be between 3 and 10 degrees; and
wherein the rolled lip is formed continuously into the skirt and uninterruptedly around the well covering all sides and all corners defined by the lid, and wherein the external surface of the skirt has a length defined along a longitudinal plane and has a lateral width and wherein the lower edge of the skirt terminates at an edge on the longitudinal plane and where a point of the rolled lip is coincident with the lower edge of the skirt on the longitudinal plane.
