A plastic container includes a shoulder portion having an annular rib defined therein and a generally cylindrical main body portion having a longitudinal axis. At least one gripping recess is defined in the main body portion that has an oblong shape when viewed in front elevation and that is defined in part by a curved concave inner surface when viewed in side elevation. The gripping recess includes a plurality of horizontal indentations, each of which is sized to receive a finger of a consumer when the plastic container is being gripped by the consumer.

A plastic container according to claim 13, wherein each of said horizontal indentations is curved as viewed in horizontal cross-section. 18. A plastic container according to claim 13, wherein each of said horizontal indentations is convexly curved as viewed in horizontal cross-section. 19. A plastic container according to claim 13, wherein each of said horizontal indentations is convexly curved as viewed in horizontal cross-section so as to have an external radius, said external radius being within a range of about 20 percent to about 70 percent of said maximum outer diameter. 20. A plastic container according to claim 13, wherein said gripping recess comprises at least three of said horizontal indentations. 21. A plastic container according to claim 13, wherein the annular rib is convex. 22. A plastic container according to claim 1, wherein the ratio of the average radius of curvature to the maximum outer diameter of the container is substantially within a range of about 0.15 to about 0.25. 23. A plastic container according to claim 13, wherein the gripping recess has a curved concave inner surface having a radius within a range of about 30 percent to about 130 percent of the maximum outer diameter. 24. A plastic container according to claim 1, wherein each of said horizontal indentations has an outer surface with a longitudinal radius of curvature substantially within a range of about 0.2 inches to about 1 inch and a ratio of the longitudinal radius to the maximum outer diameter is substantially within the range of about 15 percent to about 35 percent. 25. A plastic container according to claim 13, wherein each of said horizontal indentations has an outer surface with a longitudinal radius of curvature substantially within a range of about 0.2 inches to about 1 inch and a ratio of the longitudinal radius to the maximum outer diameter is substantially within the range of about 15 percent to about 35 percent.
