Patent number: 4258859Abstract: 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.Type: GrantFiled: March 3, 1980Date of Patent: March 31, 1981Assignee: Boise Cascade CorporationInventor: Teddy M.

Patent number: 4254890Abstract: A non-sliver scored metal end closure member, and an apparatus and method for forming the same, are disclosed, characterized by the provision of a continuous scoreline between the radius and central panel portions of the end. The scoreline includes, in cross-sectional profile, a horizontal flat bottom wall, and outwardly divergent outer and inner side walls. In the preferred embodiment of the invention, the scoreline is contained in the upper horizontal surface of the metal end, the outer side wall of the scoreline being concave and having a radius less than that of the radius portion of the metal end, the bottom wall being tangent to the outer side wall. The inner side wall comprises either a flat surface arranged at an obtuse angle of about 165.degree. relative to the bottom wall, or a concave surface tangent to the bottom wall. In another modification, the inner side wall is concave and tangent to the bottom wall, the radius of the inner side wall being at least as great as that of the outer side wall.Type: GrantFiled: August 27, 1979Date of Patent: March 10, 1981Assignee: Boise Cascade CorporationInventor: Teddy M.

Patent number: 4245752Abstract: An improved lid for covering containers, sucn as tumblers or the like, has a mouthpiece with at least a portion of the mouthpiece shaped to fit within the lips of a person drinking from the container. The mouthpiece has a valve therein operated by the drinker's lips or by the application of pressure on opposite sides of resilient walled containers. The mouthpiece with valve on the lid prevents spilling of the liquid, if the container is accidentally dropped, precludes spilling of the liquid during the time the drinker is engaged in drinking the liquid from the container, even when the drinking is done under adverse conditions, and provides facilitated means for adding condiments to a hot beverage for consumption by a user. Features are further provided for more effectively securing the valve to preclude inadvertent spilling from "wave action" of the liquid within the container.Type: GrantFiled: July 26, 1979Date of Patent: January 20, 1981Inventor: Andrew B.
