A thin walled, plastic hot-fill container has a finish to receive a closure, a neck supporting the finish, a shoulder situated below the neck, a base, and a body between the shoulder and base. The body includes upper and lower margins defining a label mount area that includes a plurality of inwardly recessed vacuum panels separated by vertical posts. At least one indented reinforcing ring separates the upper and lower edges of the vacuum panels from the adjacent margins of the label mount area by a distance D. Each vacuum panel includes an inclined upper and lower margin of height H that is greater than distance D, and has corners defined by radius R, which is less than or equal to D. Lateral margins of each vacuum panel extend vertically between the corners and connect the adjacent posts to a central depressed region, each lateral margin being essentially perpendicular to the adjacent surface of the vacuum panel.

The plastic container of claim 1 wherein each vacuum panel includes lateral margins extending vertically between the corners and connecting the adjacent posts to a central depressed region, each lateral margin lying in a plane that is substantially perpendicular to the adjacent surface of the vacuum panel. 3. The plastic container of claim 2 wherein each vacuum panel includes an outwardly protruding central element that is spaced from the lateral margins of the vacuum panel by a distance greater than W. 4. The plastic container of claim 3 wherein the outwardly protruding central element of each vacuum panel has a width that is less than W. 5. The plastic container of claim 3 wherein the outwardly protruding central element of each vacuum panel is spaced from the container longitudinal axis by a distance that is less than the spacing between the posts and the container longitudinal axis. 6. The plastic container of claim 3 wherein the outwardly protruding central element of each vacuum panel is surrounded by a surface spaced a uniform distance from the container longitudinal axis. 7. The plastic container of claim 1 wherein an indented ring separates the body portion including the label mount area from the shoulder area. 8. The plastic container of claim 7 wherein a first bumper portion protrudes radially outward from the body portion above the label mount area upper margin. 9.
