Container

A nestable container comprising, a deformable metallic container body adapted to contain a product therein and having a bottom wall and frustoconical side wall which has a tubular upper portion terminating in an open end, a deformable metallic closure for said container body, said closure having a main body adjoined at its outer edge by an annular flange, said flange having a roughly U-shaped cross-sectional configuration defined by a bight with an inner leg portion and an outer leg extending from opposite ends of said bight, said inner leg portion adjoining said main body and said outer leg being disposed radially outwardly of said open end and terminating therebeneath, said tubular upper portion and said inner leg portion each being provided with an annular indentation to effect a seam between said tubular upper portion and said inner leg portion, one of said tubular upper portion and said inner leg portion being made of metal which is stronger than the metal of the other, and at least one punch-like protrusion in said one portion which is convex into said other portion with said other portion having a corresponding can disposed around said punch-like protrusion, said closure being adapted to be removed by applying a rotational and lifting force against said outer leg causing said punch-like protrusion to deform said other metal portion by defining a thread-like groove therein due to the rotational and lifting action enabling easy removal of said closure.
