Container cap

Abstract

A container cap for use on an open top container having an upper end portion with an upper rim surface. The container cap is adapted to be mounted and sealed thereon, such that only a lift tab and a spaced apart peripheral segment extend beyond the outer edge of the upper rim surface. The non-extended edges of the cap adjacent the sides of the lift tab provide for the easy removal of the container cap in one piece upon manual lifting of the tab.

What is claimed is:  
     
         1 . For use on an open top container having an upper end portion and an upper rim surface, a contoured container cap adapted to be mounted and sealed thereon, wherein only spaced apart lift tab and peripheral segments extend freely beyond the outer edge of the upper rim surface.  
     
     
         2 . The container cap described in  claim 1 , wherein said peripheral segment is adapted to be formed into at least one loose skirt around a portion of the upper end portion, and the lift tab is adapted to be bent downwardly.  
     
     
         3 . For use on an open top container having an upper end portion and an upper rim surface, a container cap comprising a solid central portion shaped to register at its outer peripheral edge with the container top rim surface and adapted to be secured thereto, a loose peripheral portion integral with the solid central portion adapted to be formed into a skirt around a predetermined portion of said upper end portion, and a spaced-apart lift tab integral with and extending from the solid central portion, wherein the portions of the outer peripheral edge adjacent the sides of the lift tab do not extend beyond the container upper rim surface, thereby providing for the easy removal of the container cap in one piece upon manual lifting of the tab.  
     
     
         4 . For use on an open top container having an upper end portion and an upper rim surface, a container cap comprising a solid central portion, a lift tab extending therefrom, and peripheral edge portions of shorter and longer lengths extending therefrom and adapted to be formed into respective skirts around said upper end portion, said shorter length skirts being adjacent the two side edges of said lift tab, wherein the cap is adapted to be removed in one piece from the upper rim surface upon the manual lifting of the lift tab.
