A plastic container comprised of a closed base, a body portion, and a neck portion with a dispensing opening. The closed base includes a substantially rigid support portion and a flexible portion. The body portion preferably includes a shoulder portion and a substantially rigid wall portion that includes a plurality of reinforcement formations. The container is configured so that the flexible portion of the base contracts upwardly about the support portion in response to vacuum pressures generated within the container, while the substantially rigid support portion of the sidewall remains substantially firm, for example, to accept or receive a label. If desired, the shoulder portion may include a logo and/or one or more pressure relief formations. A method for producing hot-filled, labeled containers is also disclosed.

What is claimed is: 1. A process for manufacturing and filling a container, comprising: providing, at a first location, a plastic container having a sidewall and a base, the base including a substantially flat rigid annular support portion and a flexible portion configured to flex upwardly in response to internal vacuum pressure within the container, and the sidewall including a structural reinforcement; labeling the container at the first location; transporting the container to a second location; filling the container with content at an elevated temperature; accommodating an internal pressure within the container by permitting the flexible portion to at least partially flex in the direction of the content in response to internal vacuum pressure, wherein the sidewall of the container supporting the label remains substantially rigid and unchanged. 2. The process according to claim 1, wherein the sidewall of the container includes a pressure relief formation. 3. The process according to claim 1, wherein the first location is a manufacturing location and the second location is a filling location. 4. The process according to claim 1, wherein the first location is a different facility than the second location. 5. The process according to claim 1, wherein the labeled container is moved or shipped from the first location to the second location. 6. The process according to claim 1, wherein the container is subjected to at least one additional process to impart physical properties in at least a portion of the container. 7. The process according to claim 6, wherein the at least one additional process includes a heat set process. 8. The process according to claim 1, wherein the container is a multi-layered container. 9. The process according to claim 8, wherein the container includes a barrier layer, a scavenger layer, or a barrier layer and a scavenging layer. 10. The process according to claim 1, including an estimation or determination of the amount of anticipated volume reduction in response to internal vacuum pressure within the container. 11. The process according to claim 10, including an iterative process, wherein the iterative process is designed to produce containers that, following the accommodation of internal pressure, have a desired physical structure and aesthetic quality. 12. The process according to claim 11, including making one or more modifications to the rigid portion of the container, the flexible portion of the base, or both the rigid portion of the container and the flexible portion of the base, to produce containers having a desired physical structure. 13. The process according to claim 1, wherein the structural reinforcement includes a plurality of substantially rectangular formations and adjacent lands. 14. The process according to claim 1, wherein the container is labeled at the first location prior to transporting the container to the second location. 15. The process according to claim 2, wherein a label is applied over a portion of the sidewall that includes the structural reinforcement. 16. The process according to claim 15, wherein the pressure relief formation is located above the portion of the sidewall that receives the label. 17. The process according to claim 1, wherein the sidewall includes a shoulder portion. 18. The process according to claim 17, wherein the pressure relief formation is provided in the shoulder portion. 19. A process for manufacturing and filling a container, comprising: estimating or determining the amount of anticipated volume reduction in response to internal vacuum pressure within the container; providing, at a manufacturing location, a plastic container having a sidewall and a base, the base including a substantially flat rigid annular support portion and flexible portion configured to flex upwardly in response to internal vacuum pressure within the container, and the sidewall including a structural reinforcement; labeling the container at the manufacturing location; transporting the container to a filling location; filling the container with content at an elevated temperature; accommodating an internal pressure within the container by permitting the flexible portion to at least partially flex in the direction of the content in response to internal vacuum pressure, wherein the sidewall of the container supporting the label remains substantially rigid and unchanged. 20. The process according to claim 19, including an iterative process, wherein the iterative process is designed to produce containers that, following the accommodation of internal pressure, have a desired physical structure and aesthetic quality.
