Abstract
A can end that is attached to a metal can body with a bottom end forming a cavity that may be filled with food, liquid, etc. The can end is made of metal with a bead configuration located in the outer circumference of the can end that increases its resistance to deformation when subjected to high pressure cooking environments and assists in preventing the can end from separating along the frangible score.
Claims20
A metal, food can, can end comprising:
- a center panel, wherein a center point of the can end is located within the center panel;
- a bead panel located radially outside of the center panel, the bead panel comprising:
- an inner downward bead defining a first low point;
- an outer downward bead defining a second low point, the outer downward bead located radially outside of the inner downward bead;
- and
- a first connector section extending between the inner downward bead and the outer downward bead, the first low point and the second low point each being vertically below a lowermost surface of the first connector section;
- a counter-sink section located radially outside of the bead panel;
- a wall extending upward from an outer edge of the counter-sink section;
- a curled section extending radially outward from an upper edge of the wall, wherein the curled section is configured to be crimped with an upper end of a metal can body to form a seam;
- and
- a tab, wherein the outer downward bead is a continuous bead that is concentric with the outer circumference of the can end, and further wherein the inner downward bead is a non-continuous bead having a first end and a second end, the ends positioned on opposing lateral sides of the tab.

A metal, food can, can end comprising:
- a center panel, wherein a center point of the can end is located within the center panel;
- a bead panel having a top surface and a bottom surface located radially outside of the center panel, the bottom surface of the bead panel defining:
- an inner downward bead and an outer downward bead located radially outside of the inner downward bead;
- a counter-sink section located radially outside of the bead panel;
- a wall extending upward from an outer edge of the counter-sink section;
- a curled section extending radially outward from an upper edge of the wall;
- and
- a fixation point located radially inside of the outer downward bead configured to couple an opening mechanism to the can end, wherein the outer downward bead is a continuous bead that is concentric with the outer circumference of the can end, and further wherein the inner downward bead is a non-continuous bead having a first end and a second end, the first and second ends of the inner downward bead positioned on opposing lateral sides of the fixation point.
