ABSTRACT:
A metal container drawn from a sheet of tinplate has an end wall and a tapered tubular side wall extending from the end wall to culminate in a curl which defines the mouth. The curl (4) has a convex outer annulus to engage with the lining compound (11) in a lid (6) and a concave inner annulus which serves to stiffen the curl so that a peripheral folded portion (18), which joins the inner annulus to the outer annulus, bites into the skirt of a lid when crimped onto the curl to achieve a secure closure. A method and apparatus for making the container are described.
