| 20110300249 | LIQUID OR HYDRAULIC BLOW MOLDING - An apparatus for simultaneously forming and filling a plastic container is provided. A mold cavity defines an internal surface and is adapted to accept a preform. A pressure source includes an inlet and a piston-like device. The piston-like device is moveable in a first direction wherein liquid is drawn into the pressure source through the inlet and in a second direction wherein the liquid is urged toward the preform. A blow nozzle may be adapted to receive the liquid from the pressure source and transfer the liquid at high pressure into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and creating a resultant container. The liquid remains within the container as an end product. | 12-08-2011 |

The sidewall portion defines a major container diameter of the container. The sidewall portion includes an upper vacuum absorbing region joined to a lower vacuum absorbing region at a reduced waist section. The reduced waist section forms a minor container diameter which is less than the major container diameter. In some embodiments, such configuration forms an hourglass, heat-set container, wherein the upper vacuum absorbing region and the lower vacuum absorbing region are collectively shaped to provide flexible absorption of an internal vacuum within the receptacle chamber. | 09-15-2011 |

The upper portion has a spout defining an opening into the container and a finish offset radially outwardly from the spout. A trough defines a passage into the body. The trough slopes toward the passage and defines a non-orthogonal angle relative to the longitudinal axis. According to other features, the sidewall portion is integrally formed with and extends from the upper portion to the base portion. The base portion closes off an end of the container. The finish defines a means, such as at least one thread, for attaching a closure thereon. | 04-21-2011 |

| 20100006533 | THIN WALLED HOT FILLED CONTAINER - A hot-fill container may have a shoulder portion, body portion, bottom portion, and numerous strengthening grooves and a thin-walled, flexible, bag-like, collapsible portion in the body portion. The collapsible portion may be located between the strengthening ribs. The container structure may also employ one or more vacuum panels in the body portion that may lie between the collapsible portion and the bottom portion. The vacuum panels and the collapsible body portion may move toward a central vertical axis when the container is subjected to an internal vacuum pressure. Strengthening grooves may border the collapsible body portion, which may be circular in pre-vacuum cross-section but polygonal in post-vacuum cross-section. Part of the collapsible portion may be concave inward toward a central vertical axis of the container while part of the collapsible portion may move away from the central vertical axis. Vertical columns may support the collapsible portion. | 01-14-2010 |
| 20100001440 | METHOD OF MAKING A CONTAINER HAVING BLOWN POUR SPOUT - A method of making a one-piece plastic container includes disposing a preform into a mold cavity having a mold surface. Blowing the preform against the mold surface to form an intermediate container. The intermediate container having a body portion, a spout and a moil portion. An intersection between the spout and the moil portion defines a cutting plane extending at an angle. Severing the moil portion from the spout at the intersection thereby defining an opening into the container at the spout. | 01-07-2010 |
| 20090283495 | HOT-FILL CONTAINER - A one-piece plastic container includes a container body and an upper portion having a finish. Integrally formed with the finish and extending downward therefrom is a shoulder region. The shoulder region merges into and provides a transition between the finish and a sidewall portion. The sidewall portion extends downward from the shoulder region to a base portion having a base. The sidewall portion defines a series of horizontal lands and horizontal ribs. The horizontal lands and horizontal ribs extend continuously in a vertical direction from the shoulder region to the base portion. The horizontal ribs are designed to achieve optimal performance with regard to vacuum absorption, top load strength capabilities and dent resistance. | 11-19-2009 |
