An ecology stay-on tab beverage can end has a center panel having a public side and an opposing product side. The center panel has a displaceable tear panel defined by a frangible score groove and a non-frangible hinge portion of the center panel located between a first end and a second end of the frangible score which retains the displaceable tear panel to the center panel subsequent to opening. The displaceable tear panel has a symbol thereon. The symbol conveys information to a user and is formed by a relief feature on the tear panel. The symbol and the relief feature are spaced at least 0.050 inches radially inwardly of the frangible score groove such that no portion of the symbol and the relief feature are closer than 0.050 inches to the frangible score.

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.

Safety cover mechanism for a container that comprises: a sealer; tracks positionable over the upper surface of the container; and a shutter member slidable over the tracks such as to allow covering and revealing the opening by sliding the shutter member over the tracks. The safety cover mechanism is configured such that sliding of the shutter member over the tracks away from the location of the opening of the container causes at least a portion of the sealer to unseal the opening thereby indicating that the container has been opened. A safety mechanism for containers with a pull or a stay-on tab and a press button sealer, where the tab pivotally connects to the container upper surface via a connecting element, wherein the safety mechanism is configured to prevent rotation of the tab over the axis of the connecting element for preventing unauthorized penetration to the container.
