Abstract: Disclosed is a cover mountable to a beverage container and mounting method and apparatus thereof. The container cover detachably mountable to an upper surface of a beverage container comprises a body which is formed to have substantially a disc-shaped configuration. The body is partly cut away from an edge toward a center thereof thereby to define a beverage discharging opening which has a predetermined width and a predetermined contour. The beverage discharging opening is capable of being selectively communicated with a discharging hole of the beverage container as the body is rotated. An inner end of the beverage discharging opening is delimited by a rotation guiding part which has a predetermined curvature to guide rotation of the body. The body has a straw insertion hole which is defined therein at a predetermined location to have a predetermined diameter in a manner such that a straw can be inserted therethrough.

Abstract: A press assembly for forming and attaching lift-tabs to can ends to form lift-tab can ends. A tab press is mounted on a frame for forming at least one lane of lift-tabs in a strip of metal stock material wherein the strip of metal stock material with the formed lift-tabs loosely attached thereto exits the tab press and is passed through a half twist to an inverted condition before entering a tab punching station. The tab punching station punches the formed tabs from the strip of metal stock material into a lane of formed tabs. A conveying moves the lane of formed tabs from the tab punching station to a conversion press wherein the conversion press attaches the lift-tabs to the can end.

Abstract: A rupturable can member (10) of sheet metal has a pair of scorings (16) which define a tearing strip (18) laterally. Welded onto the tearing strip (18) is a tongue (20) which has a thickened portion (24) at its welded-on end (22). This thickened portion is formed by a margin folded back towards the other free end (26) of the tongue (20).

Abstract: A can body is rolled from a sheet-metal blank (28) and has outer and inner longitudinal edges (12 and 14 respectively) which are welded to one another in an overlapping manner. Extending round the can body transversely to the longitudinal edges (12, 14) are two circumferential scorings (16) which define a tearing strip (18) laterally. The tearing strip (18) is extended by a tongue (20) which is welded onto the outer longitudinal edge (12) and which can be gripped by a key and rolled up. In a welding zone (42) which is adjacent to a starting scoring (30), the tearing strip (18) is stiffened by the welded-on tongue (20) in such a manner that it tears away from the can body reliably along the circumferential scorings (16) during the rolling up of the tongue (20).

Abstract: Disclosed is a bonded can of the key-opening type comprising a coated metal blank and a seam formed by lap-bonding outer and inner end edge portions of the coated metal blank to each other by a tape of a thermoplastic resin adhesive, wherein the adhesive is a polyamide type or polyester type adhesive, the inner end edge portion forming the seam of the bonded can is completely covered with the adhesive tape, the outer edge portion has a winding-starting tongue piece integrated therewith, a plurality of scores are formed on the outer surface of the coated metal blank from the base of the tongue piece along the entire circumference inclusive of the seam, the scores have a knife angle of 45.degree. to 120.degree. and a depth corresponding to 8 to 45% of the thickness of the metal blank, a coating of an epoxy resin having a thermal softening point of 65.degree. to 150.degree.
