Metal container and metal closure thereof

A container comprising:

• a substantially tubular metal container body having a top opening defined by a curl that is uniform about the top opening, and having a bottom opening;
• a peelable lid bonded to an upper surface of said curl to close said top opening in an airtight manner, the curl defining a circular shape in cross section where the peelable lid is bonded to the curl, an outermost edge of the peelable lid not extending beyond an outermost extent of said curl;
• and
• a metal closure comprising a generally planar centre panel and a downwardly extending sidewall depending from a peripheral region of the centre panel and terminating with an inwardly or outwardly directed fold, and a plurality of features pressed into the sidewall at respective circumferentially spaced locations between said peripheral region and the fold, wherein the radial inward extent of the features is greater than that of the fold,
• the closure and the container body having relative dimensions to allow the features to pass over said curl during closure and to be retained beneath the curl to resist removal of the closure such that the features engage the curl in a snap fit.
