Abstract
A plastic blow molded container (10) of polyethylene terephthalate has a side wall (18) at least three vertically spaced horizontal ribs (38) of an annular shape and at least (12) vertical ribs (40) spaced circumferentially and extending between the horizontal ribs to cooperate therewith to define generally rectangular panels (42) that are capable of flexing inwardly to accommodate for shrinkage upon cooling. The construction of the container allows it to have a lightweight construction according to the equation: EQU W.sub.G <12.sub.G +34V.sub.G wherein W.sub.G is the weight in grams of the container, 12.sub.G is 12 grams, and 34V.sub.G is a weight in grams that is 34 times the internal volume of the container in liters. The horizontal ribs (38), the vertical ribs (40), and the rectangular panels (42) are constructed and positioned to facilitate label application to the container side wall (18).
