ABSTRACT:
Pull tabs for easy open containers are fabricated so as to avoid the presence of burrs after severing the carrier lugs, by removing each tab from the carrier sheet by severing each lug and a portion of the tab next adjacent the lug extremity, so that the burrs are avoided. Each radius has a dimension along the periphery of the tab which is slightly greater than the width of the severed lug, and with each radius located along a portion of the periphery of the tab which remains uncurled during the fabrication process.
