Patent ID: 8109398

Claim:
A plastic container, comprising: a bottom portion; and a sidewall portion, said sidewall portion having a maximum outer diameter, and wherein said sidewall portion further comprises: a first pair of opposing first vacuum panels, said first vacuum panels each having a first substantially constant radius of curvature as measured in a horizontal plane, said first substantially constant radius of curvature being substantially constant from an upper end of each of said respective first vacuum panels to a lower end, and wherein a ratio of said first substantially constant radius of curvature to said maximum outer diameter is within a range of about 0.3 to about 2.5; and a second pair of opposing second vacuum panels, at least one of said second vacuum panels including gripping structure, said second vacuum panels each having a second substantially constant radius of curvature as measured in a horizontal plane, said second substantially constant radius of curvature being substantially constant, excluding said gripping structure, from an upper end of each of said respective second vacuum panels to a lower end, and wherein a ratio of said second substantially constant radius of curvature to said maximum outer diameter is within a range of about 0.2 to about 2.
