Abstract: Improved easy open means for containers. Especially adapted to those used for liquids, including carbonated beverages, and permitting drinking from the container or pouring out contents. An important feature is attachment of closure to container after opening to avoid litter. Main feature is an openable segment in the top defined by a score line that extends almost all around its periphery, but interrupted at one point by an unscored section which provides integral hingeable attachment means to secure the segment to the top within the container after opening. Opening of the segment is accomplished by a manually operated elongated leverage lift tab which is hingeably secured to the top by a rivet which is positioned just outside of the segment and close to the score line. The outer longer lift end of the lift tab extends over the container top beyond the segment, and the shorter inner end extends partially over the segment, and comprises a downward pressure exerting extension. When the lift end is raised, the inner end exerts high downward pressure near the score line, thereby rupturing the score line with the rupture starting near the pressure point and extending on around the periphery, and the segment is thereby hinged down into the container where it remains attached to the top by the hingeable unscored section. The lift tab is then folded back out of the way to a position just overlying the container top, and ready for drinking from the can or pouring out the contents. Other features include various lift tab pressure exerting means, depression in top for lift tab, angular positioning of lift tab for improved rupturing and less obstruction to the user, part of score line replaced by adhesive sealing for easier initial rupture, various means for stiffening segment and top.
