A container may have a base, a sidewall connected to the base, a bell connected to the sidewall, and a finish connected to the bell. The base may have strap ribs to resist deformation of the base. The sidewall may have recessed columns to resist bending, leaning, crumbling, and/or stretching. The strap ribs and recessed columns may vertically line up along a central axis of the container to communicate forces on the container vertically along the container to continuously resist deformation in the base and the sidewall.

1. A plastic container configured to hold a liquid and resist deformation, comprising: a base portion comprising a hemispherical configuration and comprising a plurality of strap ribs extending from a central portion of the base to a circular perimeter, a plurality of load ribs disposed between adjacent strap ribs, and a plurality of feet formed between the strap ribs and the load ribs, the plurality of feet comprising a resting surface of the plastic container;a sidewall comprising a grip portion extending from the base to a label panel which extends to a shoulder, the grip portion comprising a grip portion perimeter and one or more circumferentially positioned angulating grip portion ribs ranging between 1 rib and 30 ribs disposed and constrained within a linear distance of 10 centimeters, the grip portion ribs comprising a plurality of sections varying in depth including a deep rib section that transitions to a shallow rib section, and the label panel comprising a label portion perimeter and one or more label panel ribs;wherein a periphery of the sidewall is substantially perpendicular to a central axis of the interior; anda bell comprising a diameter which decreases as the bell extends from the shoulder to a neck; anda finish connected to the neck and configured to receive a closure, the neck and finish defining an opening to an interior of the container. 2. The plastic container of claim 1, wherein the one or more label panel ribs comprises a number of label panel ribs ranging between 1 rib and 30 ribs disposed within a linear distance of 10 centimeters. 3. The plastic container of claim 1, wherein the plurality of strap ribs comprises three strap ribs that are equally spaced around a circumference of the base. 4. The plastic container of claim 3, wherein the plurality of load ribs comprises six load ribs, and wherein two load ribs are equally spaced between adjacent strap ribs. 5. The plastic container of claim 1, wherein the plurality of strap ribs extends to a height along the base which is greater than a height of the plurality of load ribs. 6. The plastic container of claim 1, wherein the plurality of strap ribs extends to a height along the base which is substantially equal to a height of the plurality of load ribs. 7. The plastic container of claim 1, wherein the plurality of strap ribs extends from the base into the sidewall, thereby subdividing the base rib into a plurality of equally-sized segments. 8. The plastic container of claim 1, wherein the base further comprises a gate centered on a central axis of the container and a wall extending from the gate toward the resting surface of the plastic container. 9. The plastic container of claim 8, wherein the wall comprises a dome surrounding the gate which slopes more steeply toward the resting surface than a portion of the wall surrounding the dome. 10. The plastic container of claim 8, wherein the plurality of strap ribs extend from locations surrounding the periphery of the gate. 11. The plastic container of claim 8, wherein the plurality of strap ribs extend from the periphery of the gate. 12. The plastic container of claim 1, wherein each of the plurality of strap ribs comprises two rib side walls that extend smoothly into surrounding portions of the base. 13. The plastic container of claim 1, wherein each of the plurality of strap ribs has a depth into the base which is greater than a depth of the plurality of load ribs. 14. The plastic container of claim 1, wherein each of the plurality of strap ribs is substantially parallel to the resting surface near the central portion of the base and then extends along an upward curved path toward the sidewall of the container. 15. The plastic container of claim 14, wherein the upward curved path comprises at least a first curve and a second curve, both of the first and second curves having an increasingly positive slope. 16. The plastic container of claim 14, wherein a first straight portion is disposed between the first curve and the second curve, and a second straight portion is disposed between the second curve and a terminal end of the strap rib. 17. The plastic container of claim 16 wherein the first curve comprises a first radius, and the second curve comprises a second radius, both of the first and second radii being selected to give the upward curved path a spherical configuration, such that the container better accommodates internal pressure.
