Abstract:
1. A heat set container comprising: a base portion; a shoulder portion; a sidewall portion extending from said shoulder portion to said base portion, said shoulder portion, said sidewall portion and said base portion cooperating to define a receptacle chamber within said container into which product can be filled; and a plurality of vacuum panels equidistantly disposed about said sidewall portion; and a plurality of transition lands disposed between adjacent ones of said plurality of vacuum panels, each of said plurality of transition lands being spaced outwardly relative to said plurality of vacuum panels, wherein said plurality of vacuum panels and said plurality of transition lands cooperate to be inwardly collapsible from a first outside diameter to a second outside diameter in response to at least internal vacuum forces, said second diameter being less than said first diameter; and wherein each of said plurality of vacuum panels moves from a generally planar shape to a concave shape in response to vacuum forces and each of said plurality of transition lands moves from a concave shape to a generally planar shape in response to said vacuum forces when viewed in cross-section.
