Container closure with hinged flap

A one-piece container closure molded of resiliently yieldable plastic, said closure comprising a generally horizontal platform formed with a vertically extending dispensing opening, a closure flap, a hinge extending across said platform and supporting said flap to swing upwardly and downwardly between open and closed positions relative to said dispensing opening, said flap lying in face-to-face relation with said platform when said flap is in said closed position, said flap having a free edge extending around said flap from one end of said hinge to the other end thereof, a lift tab projecting outwardly from said free edge approximately midway along the length of the free edge to facilitate swinging of said flap to said open position, ribs upstanding from said platform and shielding the free edge of said flap when said flap is in said closed position, said ribs having adjacent ends which are spaced from one another to define a space between said ribs for said lift tab, said ribs having straight sections extending from said ends and having curved sections extending from said straight sections toward the ends of said hinge, the free edge of said flap having straight and curved sections which lie adjacent the straight and curved sections, respectively, of said ribs when said flap is in said closed position, and means on the straight sections of said ribs and coacting with the straight sections of said free edge to hold said flap releasably in said closed position.

A one-piece container closure molded of resiliently yieldable plastic, said closure comprising a generally horizontal platform formed with a vertically extending dispensing opening, a closure flap, a hinge extending across the top of said platform and supporting said flap on said platform to swing upwardly and downwardly between open and closed positions relative to said dispensing opening, said flap lying in face-to-face relation with said platform when said flap is in said closed position, said flap having a free edge extending around said flap from one end of said hinge to the other end thereof, a lift tab projecting outwardly from said free edge approximately midway along the length of the free edge to facilitate swinging of said flap to said open position, ribs upstanding from said platform and shielding the free edge of said flap when said flap is in said closed position, said ribs having adjacent straight and parallel ends which are spaced from one another to define a space between said ribs for said lift tab, said tab having parallel side edges located adjacent the ends of said ribs, means on the ends of said ribs and coacting with the side edges of said tab to hold said flap releasably in said closed position, said ribs having straight sections extending from said ends and having curved sections extending from said straight sections toward the ends of said hinge, the free edge of said flap having straight and curved sections which lie adjacent the straight and curved sections, respectively, of said ribs when said flap is in said closed position, and means on the straight sections of said ribs and coacting with the straight sections of said free edge to hold said flap releasably in said closed position.
