A sheet metal end for a container has a chuck wall which fits in a container and a seam-forming panel by which the end is end seamed to the container. The lower end of the chuck wall merges into a radiused portion which defines a channel and in accordance with the invention the radiused portion merges into a raised zone of the end through contiguous first and second portions which slope upwards from the radiused portion to a third portion which is contiguous with the second portion and merges into a central portion of the end. The second portion slopes upwards less steeply than the first portion. The third portion may be connected with the central portion through a fourth portion which slopes downwards less steeply than the third portion. A score for easy opening may be provided in a convex portion connecting the second and third portions.
