Appl. No.:

11/529486

Inventors:

Paul Kelley - Wrightsville PA, US

Justin Howell - New Cumberland PA, US

Assignee:

Graham Packaging Company, L.P. - York PA

International Classification:

B65D 90/02

US Classification:

215379, 215381, 215382, 215384, 220608, 220675, 220771

Abstract:

A container adapted to increase volume contraction and reduce pressure having four panels that are adapted to contract inwardly from vacuum forces created by contraction of container contents. The container has a sidewall including four panels. The four panels are vacuum panels, including vertical transitional walls disposed between and joining the panels and the body is adapted to increase volume contraction and reduce pressure. The panels are adapted to contract inwardly in response to internal negative pressure created during hot-fill processing and subsequent cooling of a hot liquid in the container.

International Classification:

B65D 8/18

US Classification:

215381, 215382, 215383, 215384, 220669, 220675

Abstract:

An improved blow molded plastic container having generally rounded sidewalls that are adapted for hot-fill applications has two adjacent sides and two pairs of controlled deflection panels, each pair reacting to vacuum pressure at differing rates of movement, whereby one pair inverts under vacuum pressure and the other pair remains available for increased squeezability or extreme vacuum extraction. The opposing sidewalls are symmetric relative to vacuum panel and rib shape and placement. The ribs and controlled deflection panels cooperate to retain container shape upon filling and cooling and also improves bumper denting resistance, decreases vacuum pressure within the container, and increases light weight capability.
