Leak resistant foam hinged lid container

Abstract

A leak resistant foam hinged lid container includes a base and a lid joined by a hinge allowing the lid to be pivoted about the hinge onto the base to close the container. The lid includes a first uninterrupted sealing ring which engages a second uninterrupted sealing ring on the base when the container is closed providing an uninterrupted leak resistant seal between the first and second sealing rings.

What is claimed is:  
     
         1  A leak resistant hinged container, comprising: 
 a base,  
 a hinge on said base,  
 a lid hinged to said base by said hinge; said lid adapted to be pivoted about said hinge to engage said base upon closure of said container,  
 said lid including a first sealing ring,  
 said base including a second sealing ring, and  
 said first sealing ring sealingly engaging said second sealing ring upon closure of said container.  
 
     
     
         2 . The container claimed in  claim 1  further comprising a first rim on said lid and a second rim on said base, said first sealing ring being adjacent said first rim and extending around the circumference of said lid, said second sealing ring being adjacent said second rim and extending around the circumference of said base.  
     
     
         3 . The container claimed in  claim 1  wherein said lid includes a first rim, said first sealing ring being spaced from said first rim, said base includes a second rim, said second sealing ring being spaced from said second rim  
     
     
         4 . The container claimed in  claim 1  wherein said first sealing ring includes a first planar surface, said second sealing ring includes a second planar surface, said first planar surface adapted to engage said second planar surface upon closure of said container.  
     
     
         5 . The container claimed in  claim 1  wherein said first sealing ring is located on said lid spaced from said hinge, and said second sealing ring is located on said base spaced from said hinge  
     
     
         6 . The container claimed in  claim 1  wherein said base includes a side wall and at least one divider wall, said divider wall having a flat top surface adjacent said side wall and engaged by said lid upon closure of said container.  
     
     
         7 . The container claimed in  claim 1 , wherein said lid includes a first rim, said base includes a second rim, said second rim includes an undercut that extends over a portion of said first rim upon closure of said container to lock said lid onto said base.  
     
     
         8 . The container claimed in  claim 1 , wherein said lid includes ribs and chamfered corners.  
     
     
         9 . A container, comprising: 
 a lid, and    a base,    said lid including a first continuous sealing ring extending around said lid,    said base including a second continuous sealing ring extending around said base in a location on said base to engage said first sealing ring upon closure of said lid on said base.    
     
     
         10 . The container claimed in  claim 9  further comprising a hinge connected to said lid and to said base, said first continuous sealing ring and said second continuous sealing ring being spaced from said hinge to allow an uninterrupted seal between said first and second continuous sealing rings upon closure of said lid on said base.  
     
     
         11 . The container claimed in  claim 9  wherein said first continuous sealing ring includes a first uninterrupted planar surface and said second continuous sealing ring includes a second uninterrupted planar surface located on said second continuous sealing ring to engage said first planar surface upon closure of said lid on said base  
     
     
         12  The container claimed in  claim 9  wherein said lid includes a first rim and said base includes a second rim, said second rim includes an undercut that engages said first rim upon closure of said lid on said base to lock said lid and base together with said first continuous sealing ring engaging said second continuous sealing ring.  
     
     
         13 . A hinged, leak resistant foam container, comprising 
 a base, said base having a bottom wall, a first rim on said base encompassing said bottom wall, a continuous, uninterrupted first sealing ring on said base between said bottom wall and said first rim,    a lid, said lid including a top portion, a second rim on said lid encompassing said top portion, a continuous, uninterrupted second sealing ring on said lid between said top portion and said second rim, and    a hinge coupled with said first rim and said second rim.    
     
     
         14 . The hinged, leak resistant foam container claimed in  claim 13  wherein said continuous first sealing ring includes a first planar surface and said second continuous sealing ring including a second continuous planar surface, said first planar surface engaging said second planar surface to form a continuous, uninterrupted seal upon closure of said lid onto said base.  
     
     
         15 . The hinged, leak resistant foam container claimed in  claim 13  wherein said first rim includes an undercut, said undercut in a location in said first rim to snap over said second rim upon closure of said lid onto said base.  
     
     
         16 . The hinged, leak resistant foam container claimed in  claim 13  wherein said base includes a portion of said bottom wall configured to fit onto a lid of a second said hinged, leak resistant container to stack said containers.  
     
     
         17 . The hinged, leak resistant foam container claimed in  claim 13  wherein said lid includes at least one indentation for opening said container.  
     
     
         18 . The container claimed in  claim 9  wherein said base includes a side wall and at least one divider wall, said divider wall having a flat top surface adjacent said side wall and engaged by said lid upon closure of said container  
     
     
         19 . The container claimed in  claim 9  wherein said lid includes ribs and chamfered corners.  
     
     
         20 . The hinged, leak resistant foam container claimed in  claim 13  wherein said lid includes ribs and chamfered corners
