An improved blow molded plastic non-round container having rectangular sidewalls is adapted for hot-fill applications. The hot-fill container has vacuum panel reinforcement panels with rib structures located in a label mounting area on the sidewalls. In each panel, the ribs extend across the panel and are parallel to each other where the edge of one rib faces in each array faces inward and the others in the array face outward. The inward rib resists the bulge of the panel and improves bumper denting, ease of manufacture and light weigh capability.

What is claimed is: 1. A thin-walled, plastic container having a body portion with rectangular sidewalls and a base wherein the body portion comprises a label mounting area, on at least two of the rectangular sidewalls, extending between an upper label bumper and a lower label bumper, the label mounting area comprising: a rectangular vacuum panel having an upper and lower edge, said vacuum panel having a substantially flat land area, and a plurality of ribs within each panel, said ribs being spaced apart from each other along said substantially flat land area such that a portion of said substantially flat land area is positioned between adjacent ribs, each of said plurality of ribs having either an outward or inwardly projecting rounded edge relative to said substantially flat land area, wherein said ribs are parallel to each other and the non rounded base, said ribs extend from one side of the rectangular panel to the other, wherein said rounded edge of at least one of the plurality of ribs is inwardly facing and said rounded edge of at least one of the plurality of ribs is outwardly facing. 2. The plastic container of claim 1, wherein the plurality of ribs within a vacuum panel comprises an odd number of ribs. 3. The plastic container of claim 2, wherein the plurality of ribs within a vacuum panel comprises at least three ribs. 4. The plastic container of claim 2, wherein the plurality of ribs comprises at least five ribs. 5. The plastic container of claim 1, wherein the rounded edge of at least one of the plurality of rib is inwardly facing and the edges of the remaining ribs are outwardly facing. 6. The plastic container of claim 5, wherein the rib having the inwardly facing edge is an internal rib. 7. The plastic container of claim 6, wherein the rib having the inwardly facing edge has at least one adjacent rib with an outwardly facing edge. 8. The plastic container of claim 7, wherein the rib having the inwardly facing edge has at least two adjacent ribs with an outwardly facing edge. 9. The plastic container of claim 1, wherein the rectangular sidewalls having vacuum panels are opposite each other. 10. The plastic container of claim 9, wherein the ribs within the panel form a symmetrical pattern. 11. The plastic container of claim 10, wherein the symmetrical patterns in each panel are identical. 12. The plastic container of claim 1, wherein the container is made of PET. 13. The plastic container of claim 1, wherein the container is hot-fillable. 14. The plastic container of claim 1, wherein the base is non-rounded. 15. A plastic container having a body portion with rectangular sidewalls and a base wherein the body portion comprises a label mounting area extending between an upper label bumper and a lower label bumper, the label mounting area comprising: a rectangular vacuum panel on at least two of the rectangular sidewalls, each said panel having an upper and lower edge, said vacuum panel having a substantially flat land area; and an odd-numbered plurality of ribs within each panel, said ribs being spaced apart from each other along said substantially flat land area such that a portion of said substantially flat land area is positioned between adjacent ribs, each of said plurality of ribs having either an outward or inwardly projecting rounded edge, relative to a space defined by the sidewalls, wherein said ribs are parallel to each other and the non rounded base and extend substantially from one side of the rectangular panel to the other, and wherein the rounded edge of at least one rib is inwardly facing and the edges of the remaining ribs are outwardly facing. 16. The plastic container of claim 15, wherein the plurality of ribs within a vacuum panel comprises at least three ribs. 17. The plastic container of claim 15, wherein the plurality of ribs comprises at least five ribs. 18. The plastic container of claim 15, wherein the rib having the inwardly facing edge is disposed between a pair of adjacent ribs, each of which has an outwardly facing edge. 19. The plastic container of claim 15, wherein the rectangular sidewalls having vacuum panels are opposite each other. 20. The plastic container of claim 9, wherein the ribs within the panel form a symmetrical pattern. 21. The plastic container of claim 1, wherein the thin-walled, plastic container is a hot-fill type container. 22. The plastic container of claim 15, wherein the plastic container is a hot-fill type container.
