1. A system for handling filled containers, the system comprising: a plurality of containers, each said container including a body and a base defining an inner volume, the body having a first annular portion, a second annular portion, and a sidewall portion;filling means for filling each of said containers with a product, the product being at an elevated temperature;capping means for capping and sealing each said filled container with a cap;cooling means for cooling each said filled and capped container, the cooling creating a vacuum in the container, the vacuum causing temporary distortion of the container, the temporary distortion occurring substantially at the sidewall portion, with the first annular portion and the second annular portion substantially resisting distortion; andhandling means for handling each said cooled container temporarily distorted such that one or more substantially stable touch points of the container are in contact with corresponding one or more substantially stable touch points of at least one other container, the one or more substantially stable touch points being facilitated by an associated one of the first annular portion and the second annular portion,wherein, in response to hot-filling by said filling means and capping by said capping means, each said container is caused temporarily to deform, the temporary deformation being substantially confined to the sidewall portion, the first annular portion and the second annular portion providing for substantially stable touch points such that no portion of the deformed sidewall portion of any of said containers contacts any other of said containers. 2. The system according to claim 1, wherein the substantially stable touch points are for conveyance of the containers and are comprised of at least one of the first annular portion and the second annular portion of each container. 3. The system according to claim 1, wherein, for each said container, the first and second annular portions are circular in overhead view of said container. 4. The system according to claim 3, wherein, for each said container, the first and second annular portions have different diameters. 5. The system according to claim 1, wherein, for each said container, the sidewall portion is smooth and free of any vacuum panels, grips, or ribs. 6. The system according to claim 1, wherein, for each said container, the base is circular in end view of said container. 7. The system according to claim 1, wherein, for each said container, the base is square in end view of said container. 8. The system according to claim 1, wherein said handling means handles in single file a plurality of said containers being temporarily distorted. 9. The system according to claim 1, further comprising moving means for moving a moveable element in a bottom end of the base of said container, said moving means being operative to move the moveable element from a first position to a second position, the second position being more toward an interior of said container than the first position, movement of the moveable element from the first position to the second position reducing a portion of an induced vacuum within the filled and sealed container. 10. The system according to claim 9, wherein the portion of the induced vacuum is less than the entire vacuum. 11. A system for handling filled containers comprising: a plurality of containers, each said container including a body and a base defining an inner volume, the body having a sidewall portion, a first support portion that circumscribes the sidewall portion, and a second support portion that circumscribes the sidewall portion, and the base forming a standing surface for the container and having a bottom end thereof with a moveable element operative to be movable from a first position to a second position, the first position being outwardly disposed from the second position in a longitudinal direction of the container;filling means for filling each of said containers with a product, the product being at an elevated temperature;capping means for capping and sealing each said filled container with a cap;cooling means for cooling each said filled and capped container, the cooling creating a vacuum in the container, the vacuum causing temporary distortion of the container, the temporary distortion occurring substantially at the sidewall portion, with the first support portion and the second support portion substantially resisting distortion; andhandling means for handling each said cooled container temporarily distorted such that one or more substantially stable touch points of the container are in contact with corresponding one or more substantially stable touch points of at least one other container, the one or more substantially stable touch points being facilitated by an associated one of the first support portion and the second support portion,wherein the containers having temporary distortion are handled by said handling means while arranged in a matrix with at least one inner container and a plurality of outer containers, andwherein the first and second support portions for each said inner container provide for substantially stable touch points to at least three other containers, and with the first and second support portions for each said outer container providing for substantially stable touch points to at least two other containers. 12. The system according to claim 11, wherein during said filling, said capping, said cooling, and said handling, the moveable element is at or above the standing surface at all times. 13. The system according to claim 11, further comprising repositioning means for repositioning the moveable element from the first position to the second position, the repositioning removing a portion of the vacuum. 14. The system according to claim 13, said repositioning means repositions the moveable element so as to remove the entire portion of the vacuum and to create a positive pressure in the container. 15. The system according to claim 13, wherein the portion of the vacuum is less than the entire vacuum, and the container further comprises one or more supplemental vacuum panels to remove a second portion of the vacuum. 16. The system according to claim 11, wherein the sidewall portion tapers from a first end thereof to a second end thereof. 17. A system comprising: a plurality of hot-filled and sealed plastic containers, each said plastic container including a body portion and a base portion, the base portion forming a support surface for supporting the container on a substantially flat surface;a cooler to cool the plurality of hot-filled and sealed containers, said cooling creating a vacuum in each of the hot-filled and sealed containers, each said vacuum causing temporary deformation of the corresponding container, the temporary deformation being directed to a predetermined specified portion of the container; anda conveyor to convey the containers while temporarily compensating for the vacuums created therein and maintaining stable touch points,wherein the body portion of each said container includes a first hoop ring, a second hoop ring, and a smooth sidewall between the first and second hoop rings, andwherein the conveyance of the containers is such that each said container is in contact with a plurality of other of said containers of said plurality, the first and the second hoop rings for each said container providing for substantially stable touch points for conveyance of the containers. 18. The system according to claim 17, wherein said predetermined specified portion of the container at which the temporary deformation is to be directed is the smooth sidewall, with substantially no deformation of the first hoop ring and the second hoop ring. 19. The system according to claim 17, wherein said predetermined specified portion of the container at which the temporary deformation is to be directed is one or more supplemental vacuum panels, the one or more supplemental vacuum panels temporarily compensating for the vacuum during said conveying. 20. The system according to claim 17, wherein each of the first and second hoop rings is concave and runs horizontally, when the container is upright, entirely around an entire circumference of the body portion of the container.
