Abstract
The present application describes a thin-walled single-serve perishable food container configured to be economically manufactured from metal and useable by a consumer in the existing single-serve metal container, for example, a disposable single-serve metal yogurt cup. The thin-walled container has a top flange coupled to a bottom with a cylindrical wall and a conical sidewall that extends inwardly from the top flange, such that a diameter of the bottom is less than a diameter of the top flange. The thin-walled container may house other foods, such as ground or pulverized organic or synthetic powdered mixtures or dried food. The container may also have a cover or lid that hermetically seals the contents.
Claims20
A thin-walled metal container comprising:
- a circular top flange laying within a plane and extending between an outside edge and a circular inside edge centered on a longitudinal, central axis, the circular inside edge having a first diameter;
- an edge portion extending from the top flange outwardly from the central axis and bent inwardly toward the central axis, wherein a cross-sectional shape of the edge portion has a curved portion having a first radius;
- a cylindrical wall extending perpendicular to, and from, the inside edge of the top flange and being parallel to the central axis, the cylindrical wall terminating at a wall edge having the first diameter;
- a bottom including a circular central wall parallel to the top flange and centered upon the central axis and terminating at a bottom edge that has a second diameter that is less than the first diameter;
- and
- a conical sidewall extending from the wall edge to the bottom edge.
A metal container, comprising:
- a top flange extending along a plane between an outside edge and a circular inside edge with a first diameter, the top flange centered on a central axis;
- a cylindrical wall extending perpendicular to, and from, the inside edge of the top flange and being parallel to the central axis, the cylindrical wall terminating at a wall edge having the first diameter;
- a bottom including a circular central wall parallel to the plane, the bottom is centered on the central axis, the central wall including a trough at its periphery, the bottom terminates at a bottom edge that has a second diameter that is less than the first diameter;
- a conical sidewall extending from the wall edge to the bottom edge;
- and
- a cover coupled to the circular inside edge of the top flange, the cover forming a hermetic seal that seals contents stored within the metal container.

- a bottom including a circular central wall parallel to the top flange and centered upon the central axis, the central wall including a trough at its periphery, the trough including a depth and a cross-sectional shape having a second radius with the trough terminating at a bottom edge having a second diameter being less than the first diameter;
- a conical sidewall extending from the wall edge to the bottom edge;
- and
- a cover encircling the circular inside edge of the top flange, the cover forming a hermetic seal that pressure seals contents stored within the metal container.
