A plastic container that is adapted for adjustment to internal volumetric changes includes a container body defining an internal space and having a main body portion that defines a longitudinal axis and an outer diameter. The main body portion is substantially cylindrical at its outer diameter, and includes first and second recessed flexible vacuum uptake panels, each of which is constructed and arranged to flex inwardly to provide vacuum uptake when a sufficient underpressure exists in the internal space relative to ambient external pressure. The main body portion further includes a front side defining a first curved sidewall portion between the first and second recessed panels and a rear side defining a second curved sidewall portion between the first and second recessed panels. The first curved sidewall portion has a length L1 as viewed in horizontal cross-section that is less than a length L2 of the second curved sidewall portion. Each of the recessed panels has an upper portion and a lower portion, and each recessed panel is tapered so that the upper portion is recessed with respect to the outer diameter to a greater extent than the lower portion is recessed with respect to the outer diameter. This optimizes the usable surface area of the vacuum panels and forms a tapered grip configuration that enhances grippability of the plastic container by consumers.

1. A plastic container, comprising: a container body defining an internal space, said container body having a sidewall defining a longitudinal axis and further defining a main body portion having an outer diameter, said main body portion being substantially cylindrical at said outer diameter; andat least one recessed panel defined in said main body portion, said recessed panel having an upper portion, a lower portion and a central portion positioned between the upper and lower portions, and wherein said recessed panel is angled relative to the longitudinal axis with said upper portion recessed relative to the sidewall at the outer diameter to a greater extent than the lower portion is recessed relative to the sidewall at the outer diameter when the container body is in an as-formed condition. 2. A plastic container according to claim 1, further comprising a second recessed panel defined in said main body portion and angled relative to the longitudinal axis. 3. A plastic container according to claim 1, wherein said main body portion has an uppermost portion with said outer diameter above said recessed panel. 4. A plastic container according to claim 1, wherein said upper portion is recessed with respect to the sidewall at the outer diameter by a first maximum depth D1, and wherein said lower portion is recessed with respect to the sidewall at the outer diameter by a second maximum depth D2, and wherein a ratio D1/D2 of said first maximum depth to said second maximum depth is within a range of about 1.1 to about 2.5. 5. A plastic container according to claim 4, wherein said ratio D1/D2 of said first maximum depth to said second maximum depth is within a range of about 1.3 to about 1.9. 6. A plastic container according to claim 5, wherein said ratio D1/D2 of said first maximum depth to said second maximum depth is within a range of about 1.5 to about 1.7. 7. A plastic container according to claim 1, wherein said recessed panel is configured to flex inwardly to provide vacuum uptake when a sufficient underpressure exists in said internal space relative to ambient external pressure. 8. A plastic container according to claim 2, wherein said main body portion includes a front side defining a first curved portion between said first and second recessed panels; and a rear side defining a second curved portion between said first and second recessed panels; and wherein said first curved portion has a length L1 as viewed in horizontal cross-section that is less than a length L2 of said second curved portion. 9. A plastic container according to claim 8, wherein a ratio of said length L1 of said first curved portion to said length L2 of said second curved portion is within a range of about 1.4 to about 2.0. 10. A plastic container according to claim 1, wherein said container body is fabricated from a material comprising polyethylene terephthalate. 11. A plastic container that is adapted for adjustment to internal volumetric changes, comprising: a container body defining an internal space, said container body having a sidewall defining a longitudinal axis and further defining a main body portion having an outer diameter, said main body portion being substantially cylindrical at said outer diameter; andat least one recessed flexible vacuum uptake panel defined in said main body portion that is configured to flex inwardly to provide vacuum uptake when a sufficient underpressure exists in said internal space relative to ambient external pressure, said recessed panel having an upper portion, a lower portion and a central portion positioned between the upper and lower portions, and wherein said recessed panel is angled relative to the longitudinal axis with said upper portion recessed relative to the sidewall at the outer diameter to a greater extent than the lower portion is recessed relative to the sidewall at the outer diameter when the container body is in an as-formed condition. 12. A plastic container according to claim 11, further comprising a second recessed panel defined in said main body portion and angled relative to the longitudinal axis. 13. A plastic container according to claim 11, wherein said main body portion has an uppermost portion with said outer diameter above said recessed panel. 14. A plastic container according to claim 11, wherein said upper portion is recessed with respect to the sidewall at the outer diameter by a first maximum depth D1, and wherein said lower portion is recessed with respect to the sidewall at the outer diameter by a second maximum depth D2, and wherein a ratio D1/D2 of said first maximum depth to said second maximum depth is within a range of about 1.1 to about 2.5. 15. A plastic container according to claim 14, wherein said ratio D1/D2 of said first maximum depth to said second maximum depth is within a range of about 1.3 to about 1.9. 16. A plastic container according to claim 15, wherein said ratio D1/D2 of said first maximum depth to said second maximum depth is within a range of about 1.5 to about 1.7. 17. A plastic container according to claim 12, wherein said main body portion includes a front side defining a first curved portion between said first and second recessed panels; and a rear side defining a second curved portion between said first and second recessed panels; and wherein said first curved portion has a length L1 as viewed in horizontal cross-section that is more than a length L2 of said second curved portion. 18. A plastic container according to claim 17, wherein a ratio of said length L1 of said first curved portion to said length L2 of said second curved portion is within a range of about 1.4 to about 2.0. 19. A plastic container according to claim 11, wherein said container body is fabricated from a material comprising polyethylene terephthalate. 20. A plastic container that is adapted for adjustment to internal volumetric changes, comprising: a container body defining an internal space, said container body having a sidewall defining a longitudinal axis and further defining a main body portion having an outer diameter, said main body portion being substantially cylindrical at said outer diameter with a substantially circular cross-section in plan view;first and second recessed flexible vacuum uptake panels defined in said main body portion, each of which is configured to flex inwardly to provide vacuum uptake when a sufficient underpressure exists in said internal space relative to ambient external pressure;said main body portion further including a front side defining a first curved portion between said first and second recessed panels and a rear side defining a second curved portion between said first and second recessed panels, said first curved portion having a length L1 as viewed in horizontal cross-section that is more than a length L2 of said second curved portion; and whereineach of said recessed panels has an upper portion, a lower portion and a central portion positioned between the upper and lower portions, and wherein each of said recessed panels is angled relative to the longitudinal axis with said upper portion recessed relative to the sidewall at the outer diameter to a greater extent than the lower portion is recessed relative to the sidewall at the outer diameter when the container body is in an as-farmed condition. 21.
