An easy-open can end for making an opening therethrough suitable for pouring comprises an end plate, a score line in the end plate defining most of the periphery of a tear panel while leaving a hinge, and a protrusion formed on the tear panel. To open the easy-open can end, the protrusion is pressed down by a rotating bar horizontally rotated over the protrusion or by a body vertically hitting the protrusion to cause relative vertical movement between the tear panel and the remainder of the end plate, rupture of the score line, and swinging of the tear panel down about the hinge to an open position.

A metal easy open can end adapted for closing a metal can body is proposed. The can end has a score (27) defining a removable panel (26) and a tab (23), located at an edge region of the panel, for applying a force to the panel to allow the panel to be removed in a tear direction. The panel (26) has at least one embossed and/or debossed rib (25 a-c) extending substantially in said tear direction from a location or locations proximal to said tab to a location or locations proximal to an end of the panel opposite to said edge region. The rib(s) have a depth or height of at least 0.6 mm relative to surrounding panel regions along at least a part of the rib extent.

An ecology stay-on tab beverage can end has a first curvilinear segment of frangible score severable to form a vent region and a pressure equalization port. A second curvilinear segment of frangible score has opposing terminal ends separated by a hinge segment of the center panel. The second curvilinear segment of frangible score is severable to form a pour opening. A lifting of a lift end of a tab actuates an opening sequence in which the first curvilinear segment of frangible score is severed causing the vent region and the pressure equalization port to form before the pour opening is completely formed.
