A plastic container comprises an upper portion including a finish, a lower portion including a base, a sidewall extending between the upper portion and the lower portion, the sidewall defining a central longitudinal axis of the container, and at least two vacuum panels located in the sidewall and separated by a substantially longitudinal rib having a wavy longitudinal profile. Each vacuum panel comprises a first portion having a first cross-section in a plane substantially transverse to the longitudinal axis, and a second portion having a second cross-section in a plane substantially transverse to the longitudinal axis, the second cross-section being arced to a greater extent than the first cross-section.

What is claimed is: 1. A plastic container comprising: an upper portion including a finish; a lower portion including a base; a sidewall extending between the upper portion and the lower portion, the sidewall defining a central longitudinal axis of the container; at least two vacuum panels located in the sidewall and separated by a substantially longitudinal rib having a wavy longitudinal profile, each vacuum panel comprising a first portion having a first cross-section in a plane substantially transverse to the longitudinal axis, and a second portion having a second cross-section in a plane substantially transverse to the longitudinal axis, the second cross-section being arced to a greater extent than the first cross-section; and wherein at least one of the vacuum panels has left and right longitudinal borders that are wavy and have substantially complementary geometries disposed laterally opposite one another throughout. 2. The plastic container of claim 1, wherein the rib has a substantially sinusoidal longitudinal profile. 3. The plastic container of claim 1, wherein the left and right borders are substantially sinusoidal in shape. 4. The plastic container of claim 1, comprising six vacuum panels separated by six substantially longitudinal ribs. 5. The plastic container of claim 1, wherein the first cross-section is arced away from the central longitudinal axis. 6. The plastic container of claim 5, wherein the second cross-section is arced away from the central longitudinal axis to a greater extent that the first cross-section. 7. A plastic container comprising: an upper portion including a finish; a lower portion including a base; a sidewall extending between the upper portion and the lower portion, the sidewall defining a central longitudinal axis of the container; and at least one vacuum panel located in the sidewall, the vacuum panel defined by left and right borders that are wavy in shape, and have substantially complementary geometries disposed laterally opposite one another throughout, and a substantially longitudinal rib having a wavy longitudinal profile located adjacent the vacuum panel, the vacuum panel comprising a first portion having a first cross-section in a plane substantially transverse to the longitudinal axis, and a second portion having a second cross-section in a plane substantially transverse to the longitudinal axis, the second cross-section being arced to a greater extent than the first cross-section. 8. The plastic container of claim 7, wherein the left and right borders are substantially sinusoidal in shape. 9. The plastic container of claim 7, further comprising: a plurality of the vacuum panels located around the sidewall; and a substantially longitudinal rib located between each adjacent pair of the vacuum panels. 10. The plastic container of claim 7, wherein the substantially longitudinal rib has a substantially sinusoidal longitudinal profile. 11. The plastic container of claim 7, wherein the first cross-section is arced away from the central longitudinal axis. 12. The plastic container of claim 11, wherein the second cross-section is arced away from the central longitudinal axis to a greater extent than the first cross-section. 13. A method of blow molding a plastic container, comprising: (a) forming an upper portion; (b) forming a lower portion including a base; (c) forming a sidewall extending between the upper portion and the lower portion, the sidewall defining a central longitudinal axis of the container; (d) forming at least two vacuum panels located in the sidewall and separated by a substantially longitudinal rib having a wavy longitudinal profile, each vacuum panel comprising a first portion having a first cross-section in a plane substantially transverse to the longitudinal axis, and a second portion having a second cross-section in a plane substantially transverse to the longitudinal axis, the second cross-section being arced to a greater extent than the first cross-section; and wherein the at least two vacuum panels are defined by left and right borders that are wavy in shape and have substantially complementary geometries disposed laterally opposite one another throughout. 14. The method of claim 13, further comprising the step of forming a finish on the upper portion of the container. 15. A method of blow molding a plastic container, comprising: (a) forming an upper portion; (b) forming a lower portion including a base; (c) forming a sidewall extending between the upper portion and the lower portion, the sidewall defining a central longitudinal axis of the container; and (d) forming at least one vacuum panel in the sidewall, the vacuum panel defined by left and right borders that are wavy in shape and have substantially complementary geometries disposed laterally opposite one another throughout, and a substantially longitudinal rib having a wavy longitudinal profile located adjacent the vacuum panel, the vacuum panel comprising a first portion having a first cross-section in a plane substantially transverse to the longitudinal axis, and a second portion having a second cross-section in a plane substantially transverse to the longitudinal axis, the second cross-section being arced to a greater extent than the first cross-section. 16. The method of claim 15, further comprising the step of forming a finish on the upper portion of the container.
