ABSTRACT:
An improved scored metal end closure member for composite containers and the like is disclosed, together with the method and apparatus for forming the same, characterized in that a fully or partially removable panel portion is defined in the central panel portion by a scoreline of novel no-fin configuration. The scoreline--which is formed in one horizontal surface of the central panel portion by a truncated wedge score indenting device--has a generally trapezoidal configuration including a flat bottom wall, and generally divergent side walls. The opposite horizontal surface of the central panel portion is stepped to define a region of reduced thickness that extends from a location opposite one edge of the scoreline bottom wall in a direction away from the scoreline. Consequently, during progressive removal of the removable panel portion, the formation of sharp fins or projections on the residual lip remaining on the metal end is avoided. The scoreline may be formed in either the upper surface or the lower surface of the central panel portion of the metal end, and the stepped relieved portion may extend radially outwardly from a point opposite the juncture between the scoreline bottom and outer side walls, or radially inwardly from a point opposite the juncture between the scoreline bottom and inner side walls.
