Patent ID: 8297457

Claim:
A closure for a container, the container having a neck and a mouth at an upper end of said neck, said closure comprising: 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, an end wall having a top surface coupled to and extending diametrically across the upper end of said skirt and about a substantial portion of the periphery for closing the upper end of said skirt and the mouth of said container when said closure is applied to said container, said end wall having an area defined within the upper end of the skirt defining one or more openings therethrough for the dispensing of a product contained within said container, a flip-open lid hingedly connected by a hinge to a side of the skirt about the perimeter of said closure for movement of said lid relative to said end wall between a closed position in which said lid overlies and closes said one or more openings in said end wall and an open position in which said lid is clear of said one or more openings for permitting the dispensing of said product, the lid having two side edges and an outer edge defining a portion of a periphery of the lid and a top lid surface, each side edge having 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, and a snap lock for retaining said lid in its closed position, wherein said end wall having shoulders integrally formed with said end wall and said skirt proximate the upper end of said skirt on opposite sides of said lid hinge, each shoulder having a substantial portion formed as an upward extension of the skirt and an insubstantial portion located above the end wall free of the skirt, said shoulders extending upwardly from the top surface of the end wall and proximate to and spaced upwardly from a portion of a periphery of the end wall with each shoulder having a proximal end adjacent one side of the hinge and an inner side edge angling outwardly away from the hinge and corresponding to the angle of the side edges of the lid, a distal end at about the periphery of the skirt, the inner edge defined between the proximal end and the distal end, a peripheral surface extending upward from the periphery and spaced upwardly from the upper end of the skirt and extending upwardly from the top surface of the end wall defining a top shoulder surface that is substantially flush with the top lid surface when the lid is in the closed position, wherein said shoulders at least in part extend across portions of said end wall such that the thickness of said end wall in the regions of said shoulders is substantially thicker than a thickness of said end wall free of the shoulders.
