Abstract
A metal food can including a metal sidewall is provided. The diameter of the sidewall varies at different axial positions along the sidewall. The can includes a can end coupled to an end of the metal sidewall, and a plurality of circumferential beads formed in the metal sidewall. The shape of each circumferential bead varies based upon the diameter of the section of the sidewall in which the beads are formed.
Claims14
A metal can for holding and storing food comprising:
- a container end;
- a non-cylindrical metal sidewall comprising:
- a center section having a first diameter;
- an upper sidewall section located above the center section having a second diameter different than the first diameter, the upper sidewall section extending radially relative to the center section to provide a transition from the first diameter to the second diameter;
- a lower sidewall section located below the center section having a third diameter different than the first diameter, the lower sidewall section extending radially relative to the center section to provide a transition from the first diameter to the third diameter wherein the first diameter is less than the second diameter and the third diameter;
- a plurality of circumferential beads formed in the metal sidewall, wherein a circumferential bead is formed in each of the center section, the upper sidewall section and the lower sidewall section;
- wherein each of the plurality of circumferential beads has a maximum bead depth as measured between a radially outermost point of the bead and a radially innermost point of the bead, wherein the maximum depth of the circumferential bead formed in the upper sidewall section is less than the maximum depth of the circumferential bead formed in the center section and the maximum depth of the circumferential bead formed in the lower sidewall section is less than the maximum depth of the circumferential bead formed in the center section.

- a bead panel comprising a plurality of circumferential beads formed from a continuous series of radially outwardly extending curved surfaces and radially inwardly extending curved surfaces positioned between each radially outwardly extending curved surface, each radially outwardly extending curved surface and each radially inwardly extending curved surface extending circumferentially around the metal sidewall, wherein the bead panel is formed in the metal sidewall and extends continuously through the upper sidewall section, center section and the lower sidewall section;
- wherein a maximum radial depth of each bead of bead panel, as measured between a radially outermost point of the radially outwardly extending surface of the bead and a radially innermost surface of the adjacent radially inwardly extending curved surface of the bead, decrease as the radial distance between the bead panel and a longitudinal axis of the can increases;
- wherein first diameter is less than the second diameter and the third diameter.
