Closure indicator for cup lid

Abstract

A lid for a container including a closure surface, a circumferential rim extending about a periphery of the closure surface with the rim including an outer side wall, an inner side wall and a transition wall interconnecting the outer side wall and the inner side wall with the closure surface extending from the inner side wall and at least one cut out formed in at least one of the inner side wall, the outer side wall and the transition wall such that a portion of a brim of the container is visible through the cut out when the lid is properly positioned on the container. A method and apparatus for forming such lid includes providing a substantially planar blank from which the lid is to be formed, providing at least one forming die having a surface configuration conforming to a predetermined configuration of the lid, positioning the blank adjacent the forming die, conforming the blank to the configuration of the die and forming at least one cut out section in the rim of the lid wherein at least a portion of an associated container is visible through the cut out when the lid is positioned on the associated container. The apparatus having at least one forming die having a surface configuration conforming to the configuration of the lid, forming device for conforming a blank to the surface of the forming die and a cut out forming device for forming at least one cut out in the circumferential rim of the lid in a manner such that at least a portion of an associated container is visible through the cut out when the lid is positioned on the associated container.

27 . A lid for a container, comprising 
 a closure surface;    a circumferential rim extending about a periphery of said closure;    a plurality of cut outs formed in said circumferential rim, at least one cut out being formed in each of said quadrants of said circumferential rim, and    at least one access opening formed in said closure surface for permitting access to contents of the container;    wherein at least a portion of a brim of the container is visible through each of said plurality of cut outs when the lid is positioned on the container.    
     
     
         28 . The lid of claim  27 , wherein said plurality of cut outs are mutually spaced about said circumferential rim of the lid.  
     
     
         29 . The lid of claim  27 , wherein said circumferential rim includes at least an outer wall and a transition wall extending between said outer side wall and said closure surface.  
     
     
         30 . The lid of claim  29 , wherein said plurality of cut outs are formed in said transition wall of said circumferential rim.  
     
     
         31 . The lid of claim  29 , wherein said plurality of cut outs are formed in said outer wall of said rim.  
     
     
         32 . The lid of claim  29 , wherein said cut outs are formed in both said outer wall and said transition wall of said lid.  
     
     
         33 . The lid of claim  27 , wherein there are two diametrically opposed pairs of cut outs formed in said circumferential rim of the lid.  
     
     
         34 . A lid for a container comprising: 
 a closure surface;    a circumferential rim extending about a periphery of said closure surface; and    a plurality of cut outs formed in said circumferential rim, at least two of said plurality of cut outs being spaced apart a circumferential distance equal to or greater than a respective quadrant of said closure surface;    wherein at least a portion of a brim of the container is visible through each of said plurality of cut outs where the lid is positioned on the container.    
     
     
         35 . The lid of  claim 34 , wherein said plurality of cut outs are mutually spaced about said circumferential rim of the lid.  
     
     
         36 . The lid of  claim 34 , wherein said circumferential rim includes at least an outer wall and a transition wall extending between said outer side wall and said closure surface.  
     
     
         37 . The lid of  claim 36 , wherein said plurality of cut outs are formed in said transition wall of said circumferential rim.  
     
     
         38 . The lid of  claim 36 , wherein said plurality of cut outs are formed in said outer wall of said rim.  
     
     
         39 . The lid of  claim 36 , wherein said cut outs are formed in both said outer wall and said transition wall of said lid.  
     
     
         40 . The lid of  claim 34 , wherein there are two diametrically opposed pairs of cut outs formed in said circumferential rim of the lid.
