Heat set container
View Patent ↗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 sidewall 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 and the 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.
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.
2. The heat set container according to claim 1 wherein each of said transition lands comprises a radiused cross-section, each of said transition lands varying from a first radius to a second radius in response to the vacuum forces, said second radius being smaller than said first radius.
3. The heat set container according to claim 1 wherein at least one of said plurality of vacuum panels and at least one of said plurality of transition lands defines a collapsible member, said collapsible member extending longitudinally along said sidewall and said shoulder portion.
4. The heat set container according to claim 1 wherein at least one of said plurality of vacuum panels and at least one of said plurality of transition lands defines a collapsible member, said collapsible member extending longitudinally along said sidewall and said base portion.
5. The heat set container according to claim 1 wherein at least one of said plurality of vacuum panels and at least one of said plurality of transition lands defines a collapsible member, said collapsible member extending longitudinally along said shoulder portion, said sidewall, and said base portion.
6. The heat set container according to claim 1 wherein said base portion comprises an upswept surface coupled to said sidewall portion, said upswept surface articulating upward in response to internal vacuum forces.
7. The heat set container according to claim 1 wherein each of said plurality of vacuum panels comprises a radiused cross-section, said vacuum panels varying from a first radius to a second radius in response to the vacuum forces, said second radius being smaller than said first radius.
