A drawn aluminum can shell has a peripheral crown which is double-seamed with an end portion of an aluminum can body to provide a can end having a generally flat center panel connected by an inclined curved or straight panel wall to an inner wall of an annular U-shaped countersink. The countersink has an outer wall which connects with a lower wall portion of a chuck wall, and the chuck wall has an upper wall portion which connects with an inner wall of the crown. The chuck wall also has an intermediate wall portion forming a break, and the inner bottom width of the countersink is less than the radial width of the panel wall.

The invention refers to a can lid for an aluminum beverage can. The can lid has a pull tab, a chuck wall defining a plug diameter, a countersink and central panel having a panel radius. On the central panel, a score line defining a tear panel and a rivet for connecting a pull tab to the can lid are arranged. The rivet extends through a rivet island that is arranged between an opening part of the pull tab and a handle part of the pull tab. The lid has lid plug diameter of between 45 to 49 mm, an outside diameter of between 52 to 55 mm and a weight of less than 1.9 grams. The central panel has a thickness of less than 0.19 mm. The score line defines an area of between 300 mm.sup.2 to 350 mm.sup.2 and the score line has a shortest distance from the panel radius of less than 3 mm.

A beverage can end for seaming onto a can body may include a peripheral wall, a center panel (26), a tab (attached to the center panel by a rivet (28), a tear panel (60), a main reference line (Rm), a transverse reference line (R1), and a score (30). The end includes an anti-fracture score (40) proximate a vent score (70). The center panel includes a recess (27), in which the main score, an antifracture score, and (optionally) the anti-tension score (50) are located. The score is configured such that lifting the tab from its horizontal rest position to an intermediate position ruptures the main score portion to pivot the tear panel main portion about the hinge (70) and a second lifting operation or twisting operation of the tab ruptures the main score extension (34).

A pressure resistant basic shell, easy open end and can with easy open end, wherein the basic shell consists of a can seaming portion, a countersink portion, a ferrule arc portion, an upward extension portion of ferrule and a center panel from periphery to center in the cross section; the countersink portion also consists of a sixth arc portion and a second straight portion, and the sixth arc portion and the second straight portion are connected in a tangent way, and the second straight portion and the ferrule arc portion are connected in a tangent way; the center of the sixth arc portion is located below the upper surface of the center panel. The break probability under the failure of pressure resistance is lowered to 0.05%˜2.5%, which significantly improves the safety of use.

The present invention may comprise a main tab, a tab shield, a rim, an interior rim guard, and a tab finger port. The invention may further comprise breakable connectors among the tab, tab shield, rim, interior rim guard, and other structures, such that breakage of the connectors indicates access to a container after preventing or inhibiting access to a container, such as a beverage can.

The invention relates to a can lid of a conventional design, in particular intended for beverage cans, whose special feature comprises the fact that a substantially ring-shaped molded plastic part is fastened to the lower side of the lid surface surrounding the opening region to form an opening that is sealingly reclosable, in that a plastic stopper part is fixedly connected to the lower side of the tongue tab that is upwardly pivotable during the opening procedure and sealingly engages into the molded part, and in that the peripheral contour of the tongue tab is preferably disposed in the region of the molded part at a predefinable spacing from the stopper part.

The invention refers to a can lid for an aluminum beverage can. The can lid has a pull tab, a chuck wall defining a plug diameter, a countersink and central panel having a panel radius. On the central panel, a score line defining a tear panel and a rivet for connecting a pull tab to the can lid are arranged. The rivet extends through a rivet island that is arranged between an opening part of the pull tab and a handle part of the pull tab. The lid has lid plug diameter of between 45 to 49 mm, an outside diameter of between 52 to 55 mm and a weight of less than 1.9 grams. The central panel has a thickness of less than 0.19 mm. The score line defines an area of between 300 mm.sup.2 to 350 mm.sup.2 and the score line has a shortest distance from the panel radius of less than 3 mm.

A resealable easy open lid that is composed of a lid and a pull ring riveted on the lid; the rear end of the pull ring is composed of an outer ring body and an inner tongue of the pull ring; the tongue is provided with an arched deformation area along the edge; the arched deformation area is an edge inclined to the inner side of the lid which is formed by die stamping on the tongue of the pull ring; the tongue is provided with a part arching to the outside of the lid; after the pull ring is rotated around the riveting point, the tongue of the pull ring covers the opening zone, and when the middle part of the tongue is pressed, the arched deformation area can be overturned and deformed to make it contact with the edge of the opening area to seal the area.

A reduced length ecology tab is provided for a can end. The can end includes an end panel and a rivet affixing the tab to the end panel. The tab includes a body having first and second opposing ends, and a length measured by the distance between the first end and the second end. A nose portion is disposed at or about the first end, and a lift portion is disposed at or about the second end. The length of the tab is less than 0.985 inch.

The present invention may comprise a main tab, a tab shield, a rim, an interior rim guard, and a tab finger port. The invention may further comprise breakable connectors among the tab, tab shield, rim, interior rim guard, and other structures, such that breakage of the connectors indicates access to a container after preventing or inhibiting access to a container, such as a beverage can.
