| 20080203094 | CAN END WITH IMPROVED OPENABILITY AND DRINKABILITY - Disclosed is a can end with an improved opening and drinking convenience. The can end includes a body having an opening piece defined in a predetermined region of an upper surface thereof by scores, and a tab coupled to the body by means of a rivet. The tab has a first end located at one side of the rivet to form a grip portion, and a second end located at the other side of the rivet to form a pressure portion for pressing the opening piece. The scores include a center score formed at the center of the opening piece and having a center axis extending in the same direction as an extending direction of the tab, a first boundary score continuously extended symmetrically left and right from a first end of the center score adjacent to the rivet, and a second boundary score having a drinking line portion continuously extended symmetrically left and right from a second end of the center score opposite to the rivet, and lengthened line portions extended downward from both ends of the drinking line portion to the vicinity of both ends of the first boundary score. The first and second boundary scores divide the opening piece from the remaining region of the upper surface of the body. At least a region between the first boundary score and the second boundary score forms a stay portion. | 08-28-2008 |
