The container ( 10 ) according to claim 3 wherein said at least one reinforcing structure disposed within said periphery of said grip wall portion ( 24 ) includes a plurality of anti-slip protrusions ( 24 b , 24 c ). 5. The container ( 10 ) according to claim 1, wherein said rib ( 30 ) is of substantially the same radius of curvature as said opposed label panels ( 16 a , 16 b ) to provide a peripheral bumper. 6. The container ( 10 , 110 ) according to claim 1, wherein said vacuum wall portion ( 26 , 126 ) is located subjacent said grip wall portion ( 24 , 124 ). 7. The container ( 10 ) according to claim 6 wherein said vacuum wall portion ( 26 ) occupies substantially the entire region of said intermediate panel ( 22 a , 22 b ) below said rib ( 30 ) and between said label panels ( 16 a , 16 b ). 8. The container ( 10 ) according to claim 6 wherein said rib ( 30 ) connects said label panels ( 16 a , 16 b ) and is of substantially the same radius of curvature to provide an arcuate bumper. 9. A container according to claim 1, wherein the container has a nominal filled capacity of 64 fluid ounces and an empty weight that does not exceed 75 grams. 10. In a hot-fill blow-molded container ( 110 ) having a sidewall ( 16 ) with opposed label panels ( 16 a , 16 b ) and opposed intermediate panels ( 122 a , 22 b ) connecting the label panels ( 16 a , 16 b ) for affording gripping of the container ( 110 ) and pouring contents therefrom, the improvement whereineach intermediate panel ( 22 a , 22 b ) has a separate grip portion ( 124 ) and a separate vacuum absorption portion ( 126 ),said grip portion ( 124 ) having a wall portion ( 24 a ) insert into the container ( 110 ) and extending chordally thereof for providing opposed surfaces engageable by a user's fingers and thumb when gripping the container ( 110 ).sai d grip wall portion ( 24 a ) being rigid and having a periphery and at least one reinforcing structure disposed within said periphery to enable said grip wall portion ( 24 a ) to resist deflection when gripped and to resist flexure in response to normal vacuum conditions induced in the container ( 110 ) in response to hot filling, capping and cooling of the container contents,said separate vacuum absorption wall portion ( 126 ) being located subjacent said grip wall portion ( 124 ) and being separated therefrom by a rigid rib ( 130 ) extending between said label panels ( 16 a , 16 b ) for rigid connecting together the label panels ( 16 a , 16 b ) intermediate the grip and flex portions ( 124 , 126 ) and providing a sidewall bumper that resists flexure, andsaid separate vacuum absorption portions ( 126 ) of both intermediate panel ( 22 a , 22 b ) cooperating to provide a substantial portion of the normal hot-fill vacuum absorption required of the container sidewall ( 16 ), said vacuum wall portion ( 126 ) including a plurality of elongate flex panels ( 134 , 136 ), and at least one post ( 138 ) extending between said elongate flex panels ( 134 , 136 ). 11. The container ( 110 ) according to claim 10 wherein said elongate flex panels ( 134 , 136 ) and post ( 138 ) are disposed vertically. 12.
