The closure includes a top wall, a skirt and a plurality of tabs extending from the bottom edge of the skirt. The tabs are T-shaped and include a cross arm extending adjacent to the free end of the stem. The cap is made from a steel sheet coated with tin and a varnish or lacquer layer with the edges of the cap being formed by pinch trimming so that a corrosion-resistant layer of tin substantially covers the edges.

A twist-off closure for a container of the type having a neck with a central pouring opening and an outer sealing lip surrounding the end of said neck and a ledge surrounding said neck adjacent to said lip, said closure comprising:
- a top wall;
- a depending peripheral flange, said flange being configured to form a plurality of corrugations and a plurality of webs interconnecting said corrugations, said webs having lower-most edges;
- tabs extending from said webs, each of said tabs having an elongated stem portion joined to said web and a free end, said stem portion being narrower than said web;
- lateral protuberances extending transversely of said stem portion adjacent to said free end;
- said tabs being bent inwardly and upwardly from the lower-most edges of said webs, the free ends of said tabs being disposed adjacent to an intermediate portion of said webs, the spacing between adjacent tabs forming a passageway for drying air, said protuberances reducing the spacing between said free ends of adjacent tabs without restricting said air passageways.
