Container cover with hemmed leading edge

Abstract

A metal slide lid for a container which is formed from a metal blank, but in which substantially all of the raw metal edges of the blank are shielded by formed shapes. A pair of rolled rails depend from the top portion, are spaced by a sufficient distance to accept a container on which the lid is to slide, and the rolls are such that the raw metal edge is shielded within the roll. The non-rolled portions of the container, particularly the front edge which can be engaged by the fingers, is formed into a tight safety hemmed edge.

1 . A metal slide lid for a container comprising in combination: 
 a substantially planar top portion,    a pair of rolled rails depending from the top portion at two sides thereof and having finished edges, the rolled rails being shaped and positioned to allow the cover to slide over a corresponding lip of a container bottom, and    a forward edge of the top portion being formed with a peripheral hem, the peripheral hem formed by folding the forward edge of the top portion directly back onto itself, the peripheral hem extending between the forward edges of the rails, both the rolled rails and the hem serving to shield corresponding raw metal edges.    
     
     
         2 . The lid as in  claim 1  wherein the two sides have a forward edge and the rolled rails at the sides of the top portion extend around the rear thereof, whereby the rolled rail is continuous from the forward edge of one of the two sides to the forward edge of the other side of the two sides, and the hem is continuous between the respective forward edges of the rolled rail.  
     
     
         3 . The lid as in  claim 2  wherein the forward edges of the rails are angled to recess a roll portion of the rolled rail.  
     
     
         4 . The lid as in  claim 2  including at least one indentation in the top portion positioned to define an open or closed lid position.  
     
     
         5 . The lid as in  claim 4  including a plurality of indentations in the top portion positioned to define both open and closed lid positions.  
     
     
         6 - 8 . (Canceled)  
     
     
         9 . A slide lid for a container comprising in combination: 
 a metal blank having a substantially planar central portion and a formed periphery, part of the periphery being formed into a roll spaced from the underside of the central portion by a sufficient distance to allow the lid to slide on a lip of a corresponding container,    substantially all of the remainder of the periphery being formed into a tight hem, the tight hem formed by folding the forward edge of the top portion directly back onto itself, whereby substantially all raw edges of the blank are shielded by formed shapes.    
     
     
         10 . The lid as in  claim 9  wherein the part of the periphery which is formed into a roll extends along a major portion of two sides of the lid and around the back thereof, the hem extending around the remainder of the two sides and the front of the lid.  
     
     
         11 . The lid of  claim 10  wherein edges of the roll at the two sides adjacent the hem are angled from the planar central portion to the roll in a direction away from the hem to recess the roll.  
     
     
         12 . The lid of  claim 10  including indentations in the central portion positioned to define, when the lid is placed on a container, predetermined open or closed positions of the lid.
