20110094618 | HEADSPACE MODIFICATION METHOD FOR REMOVAL OF VACUUM PRESSURE AND APPARATUS THEREFOR - To modify the headspace in a container to remove vacuum pressure, a container has a seal or cap which may provide a temporary opening into the container which is sealable under compression to provide a controlled raising of the internal pressure as the heated contents of the container cools. A sealing chamber ( | 04-28-2011 |

20120273453 | PRESSURE CONTAINER WITH DIFFERENTIAL VACUUM PANELS - 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. | 11-01-2012 |
20120292284 | SEMI-RIGID COLLAPSIBLE CONTAINER - A semi-rigid collapsible container has a side-wall with an upper portion, a central portion, a lower portion and a base. The central portion includes a vacuum panel portion having a control portion and an initiator portion. The control portion is inclined more steeply in a vertical direction, i.e. has a more acute angle relative to the longitudinal axis of the container, than the initiator portion. On low vacuum force being present within the container panel following the cooling of a hot liquid in the container the initiator portion will flex inwardly to cause the control portion to invert and flex further inwardly into the container and the central portion to collapse. Raised ribs made an additional support for the container in its collapsed state. In another embodiment the telescoping of the container back to its original position occurs when the vacuum force is released following removal of the container cap. | 11-22-2012 |

20140026522 | Plastic Container Having A Deep-set Invertible Base and Related Methods - A plastic container comprises an upper portion including a finish defining an opening into the container, a lower portion including a base defining a standing surface, a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis, and at least one substantially transversely-oriented pressure panel located in the lower portion. The pressure panel is movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container. The standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position. | 01-30-2014 |
