ABSTRACT:
A container is provided having a deformable metal container body, adapted to contain a product therein and having a bottom wall and a side wall which has a tubular upper portion terminating in a first circumferential bead defining an open end of the container body. A deformable metal closure for the container body is provided and the closure has a main body portion adjoined at its outer edge by an annular flange which has a generally U-shaped cross-sectional configuration defined by a bight with an inner leg portion and an outer leg portion extending from opposite ends of the bight and the inner leg portion adjoins the main body portion and the outer leg portion terminates in a second circumferential bead. An annular indentation is provided in the inner leg portion of the flange and the tubular upper portion beneath the first bead with the annular indentation providing a seal between the closure and container body. The closure has pull tab means provided as a part thereof for permanently deforming at least part of its main body portion within the container body and causing at least a part of the inner leg portion to be pulled away from the tubular upper portion and its adjoining first bead thereby enabling removal of the closure from the container.
