Think of your food container as being part of a giant sugar cone. You only need the part of the cone where the diameter goes from 4.45" down to 4", so the rest of the cone isn't used. The distance from the 4" section to the pointy part of the cone is small Radius R1 and the distance from 4.45" to the pointy end is R2.

The angle 57.12° is the angle that would be created if you sliced the cone from the pointy end straight up to the top (R2) and spread the cone flat on a table.

It's easy to replicate this in your Illustrator app. Draw two circles with the correct radii, align the centers, draw a horizontal line from the center to the outer edge, then use the Rotate tool to rotate a copy of the line by -57.12° about the center. You should end up with a drawing pretty much like cwtnospam's drawing - the outer band within the angle is where you need to design your label (may want to rotate everything by 118.56° though to get the label "horizontal"). lt took me about three minutes to put this up in Illustrator here.
