A blow-molded bottle has a flexible concave perimeter surface extending between an upper peripheral margin projecting outward from the bottle neck and an outwardly protruding ring located above the sidewall upper margin. The flexible concave perimeter surface is specially dimensioned to respond to the presence of a vacuum within the bottle by forming linear segments between the upper peripheral margin and the outwardly protruding ring. The average radius of the vertical mid-point of the concave perimeter surface is generally greater than (3/π) (sin π/3) (R1+R2), and less than (6/π) (sin π/6) (R1+R2), where R1 is the outermost radius of the upper peripheral margin, and R2 is the radius of the outwardly protruding ring. The vertical midpoint radius of the flexible concave perimeter surface measured from the vertical axis can be made to vary by between one and five percent at between three and five positions around the perimeter.

The blow-molded bottle of claim 1 wherein the entire flexible concave perimeter surface is at a radius measured from the axis that is greater than the outwardly extending upper peripheral margin. 3. The blow-molded bottle of claim 1 wherein the radius of the outwardly protruding ring is greater than the outermost radius of the shoulder upper peripheral margin. 4. The blow-molded bottle of claim 1 wherein the radius of the vertical mid-point of the concave perimeter surface has an average value that is less than (6/π) (sin π/6) (R1 +R2). 5. The blow-molded bottle of claim 1 further comprising an inwardly indented ring joining the upper margin of the side wall to the shoulder portion. 6. The blow-molded bottle of claim 5 wherein the inwardly indented ring has a radius measured from the axis that is about equal to the average radius of the vertical midpoint of the concave perimeter surface. 7. The blow-molded bottle of claim 1 wherein the side wall includes vacuum responsive features. 8. The blow-molded bottle of claim 1 wherein the side wall includes a upper step defining an upper margin of a label panel and a lower step defining a lower margin of the label panel. 9. The blow-molded bottle of claim 8 wherein the label panel portion of the sidewall includes at least one continuous inwardly indented hoop ring. 10. The blow-molded bottle of claim 8 wherein the label panel portion of the sidewall includes at least one discontinuous inwardly indented hoop ring. 11. A blow-molded bottle comprising a base, a side wall having a lower margin joining the base, the side wall extending upward from the base to an upper margin, an inwardly indented ring joining the upper margin of the side wall to a shoulder portion, the shoulder portion extending upward above the inwardly indented ring and inward to a neck surrounding a vertical axis below a finish defining a opening adapted to accept a closure, the shoulder portion including a circumferentially continuous outwardly extending upper peripheral margin adjoining the neck, an outwardly protruding ring immediately above the inwardly indented ring, and a flexible concave perimeter surface joining the upper peripheral margin to the outwardly protruding ring, the entire flexible concave perimeter surface being at a radius measured from the vertical axis that is greater than the outwardly extending upper peripheral margin, the vertical midpoint of the flexible concave perimeter surface having a radius measured from the vertical axis that has an average value that is greater than (3/π) (sin π/3) (R1 +R2), where R1 is the outermost radius of the shoulder upper peripheral margin, and R2 is the radius of the outwardly protruding ring, and the radius varies from the average value by between one and five percent at four equally spaced positions around the ring perimeter. 12.

The blow-molded bottle of claim 14 wherein the side wall includes a upper step defining an upper margin of a label panel, a lower step defining a lower margin of the label panel, and vacuum responsive features located between the upper step and lower step. 16. The blow-molded bottle of claim 15 wherein the label panel portion of the sidewall includes at least one continuous inwardly indented hoop ring situated between the vacuum responsive features and one of the upper and lower label panel margins. 17. A blow-molded bottle comprising a base, a side wall having a lower margin joining the base, the side wall extending upward from the base to an upper margin, an inwardly indented ring joining the upper margin of the side wall to a shoulder portion, the shoulder portion extending upward above the inwardly indented ring and inward to a neck surrounding a vertical axis below a finish defining a opening adapted to accept a closure, the shoulder portion including a circumferentially continuous outwardly extending upper peripheral margin adjoining the neck, an outwardly protruding ring immediately above the inwardly indented ring, and a flexible concave perimeter surface joining the upper peripheral margin to the outwardly protruding ring, the vertical midpoint of the flexible concave perimeter surface having a radius measured from the vertical axis that has an average value, and which radius varies by between one and five percent of the average value at several equally spaced positions around the concave surface perimeter, the shoulder portion responding to the presence of a vacuum within the bottle by forming linear segments between the upper peripheral margin and the outwardly protruding ring coincident with the equally spaced positions. 18. The blow-molded bottle of claim 17 wherein at least an upper wall of the inwardly indented ring joining the upper margin of the side wall to the shoulder portion is vertically wavy and sufficiently vertically flexible to permit the enhancement of the wavy character of the upper wall in response to the presence of a vacuum within the bottle. 19.
