More Information
Summary:An easy-open container component comprising an end closure having an aperture therein and a reclosable two-position pull-tab having a downwardly depending plug member whose sidewall is larger at its top than at the bottom, and whose bottom surface initially is planar with, and is adhered to a sealing membrane in turn adhered to, the underside of the central panel of the end closure. Opening of the end closure is effected by pulling upwardly on the pull-tab to pull the plug member out of the aperture and to cut the sealing membrane about the edge of the rim of the aperture. Reclosure is effected by pressuredly inserting the plug member downwardly into the aperture so that the edge of the rim of the aperture pressuredly sealingly engages the larger top portion of the plug member sidewall, and so that the bottom surface of the plug member is below the plane of the underside of the central panel of the end closure.
