Abstract: A re-closure device for a pop-top can is convenient to use, is plastic or metal and has an inside end, an outside end, a bottom protrusion and two opposite sides. The pop-top can has a top lid, an annular lip around the top lid, an opening defined in the top lid and a pull-tab attached to the top lid by a pivot fastener. The inside end connects to the pivot fastener and engages simultaneously the pull-tab. The outside end has a frame that holds onto the annular lip, an outer lip for removing conveniently the re-closure device and a retaining lip extending from the outer lip to engage the annular lip to hold the re-closure device on the top lid. The bottom protrusion is held in and seals the opening.
