    Abstract: An easy open closure (10) for food or beverage containers and comprising a centre panel (27) surrounded by a circumferential score (16) and an outer seaming panel (17). The closure further comprises a tab (11), the tab being fixed to the centre panel by a rivet (12) formed in the centre panel (27) such that lifting of a radially inner region of the tab (11) forces a nose portion (24) of the tab into contact with a region of the centre panel adjacent to a radially inner edge of the circumferential score (16), thereby causing the score to fracture. A bead (19) is formed in and extending circumferentially around the centre panel inside and adjacent to the circumferential score (16) and at a radius outside of the rivet (12), the bead deviating inwardly from its circumferential path as it approaches the region in which the rivet (12) is formed, and the bead terminating adjacent to and on either side of the rivet.

    Abstract: A can for containing a liquid having a top end is disclosed. The top end has (a) a dispense area defined by a first score line and (b) a pull tab coupled to the top end by a first rivet. The pull tab punctures the dispense area to open a dispense aperture upon lifting an actuating end of the pull tab. The top end has (c) a vent area defined by a second score line and (d) a secondary lever coupled to the top end by a second rivet, and has a puncturing end for puncturing the vent area to open a vent aperture upon lifting an opposite, actuating end of the secondary lever. The secondary lever and pull tab interlock so lifting the actuating end of the pull tab triggers lifting of the actuating end of the secondary lever, opening both dispensing and vent apertures in a single movement.

  • Patent number: 4496052
    Abstract: A first part of plastic material (7), preferably a component of a package, is secured to a second part (2). Tubular projections (9) are formed in the first part and are introduced through a hole (4) in the second part. The projection (9) is shaped with an outer terminating portion (11, 12) closing the same, and forming a vaulted termination extending outwardly and provided with such a crease that it can be brought to an at least somewhat inwardly bulging position. After the second part (2) with its hole (4) has been placed on the projection (9), a surface is laid against the vaulted termination and is pressed against the same, so that it is inversely forced into its inwardly bulging position. In this position it causes such a widening of the portion (10;14) of the projection located inside of the termination that this portion forms a rivet head (13;19).

  • Patent number: 4174559
    Abstract: Two sheets of deformable material are securely fastened together without the use of adhesives, separate rivets or fasteners by forming a closed end cylindrical projection on the upper surface of the first sheet, placing the second sheet having an aperture over the first sheet, the aperture receiving the projection, and deforming the projection in the aperture to produce a tight friction fit and form a lip which overlaps the exterior rim of the aperture to limit its enlargement. In a preferred embodiment two plates are fastened together to form a rotor by striking the projection with a die having an annular groove forcing one part of the projection into the aperture and forming another part of the projection into the lip.
