Embodiment Construction

[0024] Refer to the attached figure 1 , in which a cross-sectional elevation view of one embodiment of the invention is provided. More particularly, a beverage can end 2 is depicted interconnected with a beverage can body 20, which also includes a neck 22 of the beverage can. The beverage can end 2 typically has an edge-covering bead 4 which is used to secure the beverage can end 2 to the neck 22 of the end of the beverage can body. The edge-covering bead 4 is integrally connected to one another with a fixed wall 6 which extends downwards in a substantially vertical manner. In some embodiments, the fixed wall 6 may be provided with an angle θ 1 , preferably said angle is between 0°-6°, more preferably 4°.

[0025] The lower end of the fixed wall 6 is interconnected with a reinforcing flange 8 comprising an upper lip 10 at the upper end of the reinforcing flange, and a lower lip 12 of the reinforcing flange at the lower end. The lower lip 12 of the reinforcing flange extend...

Abstract

The present invention discloses a beverage can end (2) having an outwardly concave (8) reinforcing bead with an upper lip (10) which extends outwardly beyond a substantially vertical plane defined by a downwardly extending chuck wall (6).

Description

technical field [0001] This invention relates generally to beverage can ends, and more particularly to metal beverage can ends interconnected with beverage can bodies. Background technique [0002] Beverage can ends, particularly metal beverage cans, are typically made by interconnecting a beverage can end and a beverage container body. In some cases, one end may be interconnected with the top side and the other end may be interconnected with the bottom end side of the can. More commonly, however, the ends of the beverage can are interconnected only with the top end of the beverage can body which is drawn or ironed from a flat sheet material, such as aluminum. Due to the potentially high internal pressures that can develop in carbonated beverages, beverage can bodies and can ends typically need to be able to withstand internal pressures up to 95 psi without being damaged or permanently deformed. And depending on various environmental conditions, such as heat, overfill, hig...
