Overcap

Abstract

A cap for a container having a planar centre panel 32 and a downwardly extending sidewall 40 descending from a peripheral region 33, ending with an inwardly directed curl 42 around the circumference of the sidewall. The curl has collapsed portions (figure 5, 46) and lug portions (figure 5, 48). The container has an outwardly curled edge (figure 7, 52) surrounding the opening. The lug portions may clip over the outwardly curled edge to secure the cap to the container and resist removal. The cap may be metal. There may be a channel (figure 12B, 152) that contains a sealing compound. The container may have an inwardly directed bead (figure 10, 72) extending around the opening for carrying a foil member (figure 10, 70). The foil closes the opening and is in close proximity to the cap. The container may be metal and substantially tubular. To fill the container, first the foil is affixed to the bead and then the cap is attached. Product enters through a bottom opening of the container, which then may be closed by seaming a metal end.
