Abstract
An easy open can end construction and method of making it. The pull tab and tear strip remain fully locked onto the can end, and the opening strip does not dip into the beverage. Bead members positioned externally of the tear strip not only preserve a desired orientation of the pull tab with respect to the tear strip but also serve as a guard against the user's face or tongue contacting the raw edge left after lifting the tear strip. The tear strip itself is provided with one or more protective pads to protect the user's face. A sanitary cover member overlies the tear strip and is rolled up with the pull tab and tear strip becoming interlocked therewith. A method of making the score line pattern is included so that tearing occurs along a single side of the bottom of the score line pattern to avoid a zigzag tear pattern which is dangerous to the user's tongue or lips. Finally, a method of making a rivet is included in which two metal thicknesses are joined together to avoid a leaking problem encountered in single metal thickness rivets.
