A device is provided that assists with equalizing air pressure within a container with the atmospheric air pressure as liquid is being poured from the container and includes one or more relatively short air tubes. The device is provided with the ability to simultaneously equalize pressure in the container while also providing a drip collection mechanism. The device may be configured for unidirectional pouring or multi-directional pouring.

A metal end for seaming onto a metal container body. The end comprises an outer curl, a centre panel within the outer curl, and a tab having a longitudinal axis (A). The end further comprises a rivet securing the tab to the centre panel, and a score in the centre panel having two spaced apart ends which define a hinge therebetween, the hinge lying on one side of said longitudinal axis (A), such that operation of the tab fractures the score and causes the region of the centre panel within the score to pivot about the hinge and provide an aperture in the centre panel. The score extends into a region of the centre panel that is behind a centre line (B) running through the centre of the rivet and perpendicular to said longitudinal axis (A), and on the other side of the longitudinal axis (A) from the hinge.

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 present invention relates to a closure for a container, comprising, a tab attached by rivet means to a closure part to be displaced for forming an opening in the closure, which opening is at least partly defined by a score line formed in the closure, the tab comprises a tab body connected to the rivet means, a tab rear part for finger gripping, and a tab front part of which a tab nose is located near or at the score line, such that during a closure opening procedure comprising finger gripping the tab rear part, lifting the tab rear part thereby pressing the tab nose against the closure on or near the score line, popping the score line, and scoring the score line thereby forming an opening in the closure, characterized by score line parts separated by a score line part to be popped by the tab nose, which score line parts are stronger than the popping score line part, and by stiffening means stiffening closure parts neighboring the stronger score line parts, and to a container provided with such closure.

A can closure includes a body with a center panel and a peripheral curl. The can closure body has one of a reduced panel depth, a very reduced panel depth, an extremely reduced panel depth, or a beverage can reduced panel depth.

Provided is a can body containing contents such as carbonated beverages, the can body being capable of suppressing the occurrence of an unexpected opening while increasing the internal pressure resistance. In the can body, formula (A+B).Math.E/Z<1.88 is satisfied when 0<L<Y2, with the following definitions: L=D.Math.cos (12), A=X.Math.(L+Y1Y2)/Y1, and B=L+Y1Y2, under a condition of E<Z.

A metal closure for seaming onto the end of a container, the closure comprising a centre panel defined by a circumferential score, a tab fixed to the panel by a rivet formed in the panel, and two spaced apart, elongate raised beads formed in the panel. The tab has a heel portion radially inside of the rivet and a nose portion radially outside of the rivet and adjacent to a radially inner edge of the score, such that lifting of the heel portion forces the nose portion into contact with a region of the panel adjacent to the radially inner edge of the circumferential score, thereby causing the closure to fracture partially along the score. The beads extend with a circumferential component of direction, and each has an end terminating under the tab radially between the rivet and the score about which the tab may pivot.

A can lid (14) for an aluminum beverage can comprises a pull tab (38). Further, it has a chuck wall (26) defining a plug diameter, a countersink (28) and central panel (30) having a panel radius (48). On the central panel, a score line (34) defining a tear panel (32) and a rivet (40) for connecting the pull tab to the can lid are arranged. The plug diameter is between 45 to 49 mm, an outside lid diameter is between 52 to 55 mm and a lid weight is less than 1.9 gr. 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 can end includes a center panel, an annular portion disposed about the center panel, a chuck wall disposed about the annular portion, a curl extending radially outwardly from the chuck wall, the annular portion including an annular ridge and an annular countersink, the annular countersink disposed adjacent and about the annular ridge. The annular countersink and the annular ridge are structured to resist deformation from external or reverse pressure.

A lid for a container made of metal and able to contain a substance, it comprises a closing element defined by a line of incision provided with a front portion, an opening lever disposed astride the line of incision and comprising a fulcrum front end disposed at the front of the front portion, and an intermediate region provided with a flexible tongue attached to the closing element, a mechanical element configured to attach the flexible tongue mechanically to the closing element. The mechanical element is disposed essentially tangent to the front portion of the line of incision.
