The easy open beverage can has a weakened spout portion formed in one end which is punched out from the can end and pivoted into the interior of the can. A punch tab which remains connected to the can end is used to punch the spout portion. A closure flap is foldably connected to and underlies the punch tab, and is connected to the can by the rivet which also connects the tab to the can. The closure flap is swung about the rivet to close the can opening by twisting the punch tab about the rivet. The closure flap may have a seal-enhancing polymer coating on it and a lightly biased peripheral skirt.
