  • Patent number: 6443324
    Abstract: A tab top beverage can has a compressible drinking straw held between the can bottom and an upwardly extending detachable closed cavity formed in the can top. Detachment of the cavity by a pivoting tab top uncovers a straw access orifice through which the straw is projected by the force of a previously compressed corrugated spring section formed in the straw wall. A bulge located on the straw prevents passage of the straw from the can and facilitates extension of the straw. The tab is attached to the can top by outwardly projecting lips formed on upwardly projecting closed cavities defined in the can top. The cavities extend through openings in the tab and the lips extend beyond the opening perimeters to secure the tab to the cavities and top.
