Definitions
- the present invention generally relates to the field of single-serve food containers, for example, a single-serve yogurt container.
- Conventional yogurt containers are stored in plastic containers.
- plastic is not an ideal material to contain and store yogurt given permeability and/or thermal properties of conventional plastics.
- the present invention relates specifically to an economical high-speed manufactured thin-walled metal container configured to permit dense packing for shipping to a filling facility.
- the metal containers may also store food items, including perishable food items such as yogurt.
- One embodiment of the invention relates to a thin-walled metal container.
- the container includes 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 has a first diameter.
- An edge portion extends from the flange outwardly from the central axis and bent inwardly toward the central axis.
- the cross-sectional shape of the edge portion has a curved portion with a first radius.
- a cylindrical wall extends perpendicular to, and from, the inside edge of the top flange and being parallel to the central axis. The cylindrical wall terminates at a wall edge, the cylindrical wall and the wall edge having the first diameter.
- a bottom including a circular central wall parallel to the top flange is centered upon the central axis.
- the central wall includes a trough at its periphery.
- the trough includes a depth and a cross-sectional shape having a second radius.
- the trough terminates at a bottom edge having a second diameter being less than the first diameter.
- a conical sidewall extends from the wall edge to the bottom edge.
- the top flange is centered on a central axis.
- the top flange extends along a plane between an outside edge and a circular inside edge.
- the top flange has a first diameter.
- the edge extends radially from the top flange and the central axis and is bent inwardly toward the central axis.
- a cross-sectional shape of the edge has a curved portion with a first radius.
- the cylindrical wall extends perpendicular to and from the inside edge of the top flange.
- the cylindrical wall extends parallel to the central axis and terminates at a wall edge with the first diameter.
- the bottom has a circular central wall parallel to the plane and centered on the central axis.
- the central wall includes a trough with a depth and cross-sectional shape that has a second radius at its periphery.
- the trough terminates at a bottom edge that has a second diameter that is less than the first diameter.
- the conical sidewall extends from the wall edge to the bottom edge.
- the cover is coupled to the circular inside edge of the top flange and forms a hermetic seal to seal contents stored within the metal container.
- the circular top flange lies on a plane and extends between an outside edge and a circular inside edge centered on a central axis.
- the circular inside edge has a first diameter.
- the edge portion extends from the top flange outwardly from the central axis and bends inwardly toward the central axis.
- the cross-sectional shape of the edge portion has a curved portion with a first radius.
- the cylindrical wall extends perpendicular to, and from, the inside edge of the top flange and is parallel to the central axis.
- the cylindrical wall terminates at a wall edge, having the first diameter.
- the bottom has a circular central wall parallel to the top flange and is centered on the central axis.
- the central wall has a trough at its periphery with a depth and a cross-sectional shape defining a second radius.
- the trough terminates at a bottom edge with a second diameter that is less than the first diameter.
- the conical sidewall extends from the wall edge to the bottom edge.
- the cover encircles the circular inside edge of the top flange and forms a hermetic seal that pressure seals contents stored within the metal container.
- FIG. 1 is a perspective view of a thin-walled metal food container
- FIG. 2 is a side view of the container
- FIG. 3 is a top view of the container
- FIG. 4 is a bottom view of the container
- FIG. 5 is a cross-sectional view taken along line 5-5 of FIG. 2;
- FIG. 6 is a cross-sectional view taken along line 6-6 of FIG. 2;
- FIG. 7 is a cross-sectional view taken along line 7-7 of FIG. 2;
- FIG. 8 is a dimensioned drawing of a side cross-sectional view of the container.
- the figures illustrate a thin-walled metal container 10 to store food items, such as yogurt and/or other perishable or non-perishable foods.
- the purpose of container 10 is to contain a food item and/or perishable food such as yogurt.
- the thin-walled metal container 10 may also function as a cereal bowl, intant food mix, and/or a powdered or ground drink container such as coffee, tea, and/or hot chocolate grounds.
- container 10 includes an edible food, such as a breakfast cereal, oats, or coffee is sealed within an interior of the metal container.
- a user can brake or puncture the seal to access the edible food and combine it with another food mixture within the container and/or outside the seal.
- a user removes the seal to pour milk from outside the seal on the breakfast cereal inside container 10.
- Metal container 10 is configured and formed from metal to permit the use of such containers as a substitute for plastic containers for perishable foods.
- Metal containers 10 offer advantages relating to gas permeability and perishable food interaction. The reduction in gas permeability and perishable food properties of metal containers 10 outweigh the development efforts and production costs to manufacture a satisfactory metal container.
- container 10 includes a circular top flange 12 laying within a plane and extending between an outside edge 14 and a circular inside edge 16 centered on a longitudinal, central axis 18.
- Top flange 12 has a length LI between 0.15 and 0.25 inches wide, specifically 0.196 ⁇ 0.01 inches.
- Top flange 12 has a diameter 4> 1 in the range of 3.5 and 4 inches, specifically 3.695 ⁇ 0.2 inches.
- Circular inside edge 16 has a diameter (
- an edge portion 20 extends from flange 12 outwardly from the central axis 18 and is bent inwardly toward the central axis 18.
- Edge portion 20 may extend from its periphery inwardly toward the central axis 18 a length L2 between 0.08 and 0.086 inches but preferably extends inward 0.083 inches.
- an edge length L3 is the difference between the top flange length LI minus the inward bend of length L2.
- length L3 is between 0.10 and 0.15 inches, specifically 0.11 ⁇ 0.02 inches.
- a thickness T1 of the bent top flange 12 is between 0.05 and 0.1 inches, specifically 0.086 ⁇ 0.01 inches.
- the cross-sectional shape of edge portion 20 has a curved portion 22 with a radius Rl, which is between 0.03 and 0.035 inches, specifically 0.0315 ⁇ 0.001 inches.
- a cylindrical wall 24 extends perpendicular to, and from, inside edge 16 of top flange 12. Cylindrical wall 24 is centered on and parallel to the central axis 18. Cylindrical wall 24 terminates at a wall edge 26 and has a diameter (
- Bottom 25 of container 10 includes a circular central wall 28 parallel to top flange 12 and centered on and perpendicular to the central axis 18.
- Central wall 28 includes a trough 30 at its periphery.
- Trough 30 has a depth DI, which may be between 0.06 and 0.07 inches, specifically 0.068 ⁇ 0.001 inches.
- Trough 30 has a cross-sectional shape, which may have a radius R2 between 0.020 and 0.03 inches, specifically 0.024 ⁇ 0.01 inches.
