A can lid is provided to be made of a steel plate and easy to be opened. An opening piece is enclosed by a score line formed on a periphery of a panel portion. An installation portion of a tab is attached to the opening piece at a site close to a circumference of the opening piece. The tab includes a finger grip portion that is situated closer to a center of the opening piece than the installation portion, and a nose portion that is situated on an opposite side to the finger grip portion at a radially outer side of the score line. A portion of the panel portion underneath the nose portion serves as a support section that supports the nose portion from below. An outer circumferential bead is formed on a radially outer side of the score line to enhance a bending stiffness of the support section.

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 container assembly that may be used as a can or a cup includes a container that may contain a beverage. A lid is removably coupled to the container and a retainer is removably coupled to the lid. The retainer engages the container such that the lid is retained on the container. The retainer is selectively removed from the lid such that the lid is removable from the container.

A closure body (40) is provided for installation with a liner membrane (52) on a container (44). The closure body (40) has a peripheral portion (74) for being mounted on the container (44) around an access opening (48), and a separable portion (82) that (i) is disposed laterally inwardly of the peripheral portion (74); (ii) is initially connected to the peripheral portion (74) by at least one frangible connection (86); and (iii) can be separated from the peripheral portion (74) upon breaking of the at least one frangible connection (86).

A- lid (20) for a container (21) comprises: a central surface (27) having a substantially circular shape, on which a line of weakening (30) is made, which defines a closing element (39) which can be opened by pulling, made in the central surface (27); and a drive tab (22), having at least a first end (25) to act as a fulcrum outside the line of weakening (30) connected to the closing element (39) with a rivet (23) and able to be driven so as to remove upward, the closing element (39) from the remaining part of the central surface (27), detaching it along the line of weakening (30). The line of weakening (30) is interrupted at one end of the closing element (39) opposite to the drive tab (22), so that the closing element (39) has a connection flap (34) solid with the remaining part of the central surface (27). In the case of aluminum, the rivet is located at 1.5-3.5 mm from the front part of the closing element (39). In the case of ferrous allogs, this distance is 4.0-6.0 mm.
