ABSTRACT:
An easy open pull tab system and method is adapted for use with a container of the type having a weakened score line, the severing of which permits access to the container. A fastener is joined to the container end and spaced from the score line, with a pull tab joined to the fastener through an octagonal hole, the tab having a pull ring extending from the fastener in a direction away from the score line. The pull tab includes a nose portion extending adjacent to the score line to permit the desired severing upon pulling of the pull ring in a direction away from the container end. The tab is formed with a continuous peripheral curl extending along two beams forward to the nose portion, and is provided with only two carrier lugs on opposite sides of the pull ring for use in the manufacturing of the tab. The container end is provided with a crimped ridge designed to abut a flat metal strip through which the fastener is connected to the container, to limit axial rotation of the tab about the fastener.
