Abstract
A closure for a container including a downwardly depending skirt having an upper end and a bottom end and a periphery defining a perimeter of the closure for sealable connection to the mouth of said container. Each of two side edges of the lid has a proximal end adjacent a different side of the hinge on the skirt and angling outwardly from the hinge at increasing distances from the opposing side edge to a distal end defining a different end of the outer edge. The end wall has shoulders integrally formed with the end wall and skirt proximate the upper end of the skirt on opposite sides of the lid hinge. The shoulders extend across portions of the end wall such that the thickness of the end wall in the regions of said shoulders is thicker than a thickness of said end wall free of the shoulders.
