Heat set container

摘要

A heat set container including a base portion, a shoulder portion, and a sidewall portion extending from the shoulder portion to the base portion. The shoulder portion, the sidewall portion and the base portion cooperate to define a receptacle chamber within the container into which product can be filled. A plurality of vacuum panels are equidistantly disposed about the shoulder portion. A plurality of transition lands are disposed between adjacent ones of the plurality of vacuum panels and spaced outwardly relative thereto. The plurality of vacuum panels cooperate to be inwardly collapsible from a first outside diameter to a second outside diameter in response to at least internal vacuum forces.

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 the container into which product can be filled; a plurality of shoulder vacuum panels equidistantly disposed about said shoulder portion; a plurality of transition lands disposed between adjacent ones of said plurality of shoulder vacuum panels, each of said plurality of transition lands being spaced outwardly relative to said plurality of shoulder vacuum panels; and a plurality of sidewall vacuum panels equidistantly disposed about said sidewall portion, wherein at least one of said plurality of shoulder vacuum panels and said plurality of sidewall vacuum panels 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 shoulder 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.
