Abstract
A container assembly includes a container body having a side wall encircling an axis, and a metal end for attachment to an upper edge of the side wall via heat-sealing. The outer peripheral region is shaped prior to application to the container body such that an annular channel is defined between an inner chuck wall and an outer chuck wall of the metal end. The metal end is pushed straight onto the side wall such that the upper edge of the side wall is received into the channel The surfaces of the side wall and the opposing surfaces of the chuck walls have heat-sealable material thereon. The metal end is heated to melt and fuse the heat-sealable layers, thereby sealing the metal end onto the side wall. The metal end is shaped such that the free edge of the outer chuck wall is not exposed.
