ABSTRACT:
A method of manufacturing hollow metal sheet containers and the containers produced thereby, comprising forming an annular edge roll extending radially outward at the upper end of the container, and folding the upper end outwardly so as to form an external pocket in which the edge roll is disposed. The ends of a flexible handle are inserted into this pocket at opposite sides of the container. This pocket is shaped to form an upper hollow reinforcement rim having an upwardly concave recess to receive a lid rim. The sheet metal container thereby produced comprises a partially hollow locking rim projecting outward and integral with the side wall of the container body and formed by at least three folded sections. The rim has retaining lips projecting radially inwards for the retention of the periphery of a lid on the container. These lips are bent in from a double thickness of the sheet material, the outer side of the upwardly concave recess, between those lips, being in the form of upstanding partial cylindrical portions.
