An easy-open, stay-on-tab can end has a circular end wall with a large, substantially oval tear panel defined by a score line and a hinge. A rivet adjacent the tear panel connects a tab to the end wall. The width of the tear panel, as measured perpendicular to the diameter of the end wall, is substantially greater than its length. The opening formed by lifting the rear of the tab and displacing the tear panel downwardly about its hinge provides improved pourability and drinkability of the liquid contents of the can. The area of the tear panel is at least 0.50 in2. The tear panel extends substantially to the center of the end wall and may include an upwardly projecting, closed, predominantly oval bead having a portion generally following the outline of the bight of the score line. The front end of the tab extends over the bead and cooperates with it during opening.
