Abstract: The present invention provides a plastic container having a sidewall defining a chamber and having an opening at one end into the chamber; a base extending from the sidewall and closing the second end, the base having an outer perimeter portion defining a support structure, an axially inwardly extending perimeter wall spaced radially inwardly from the support structure forming an angle with a plane normal to an axis of the container of greater than about 80°, and a flexing panel closing an end of the perimeter wall, the flexing panel moveable along an axis of the container from a first position where a central portion of the panel is below a top portion of the perimeter wall to a second position where the central portion is above the top portion of the perimeter wall to change the volume of the container; and a plurality of circumferentially spaced radial grooves on the panel.

Abstract: The present invention provides a blow molded heat set PET container having enhanced thermal properties and a first glass transition temperature and a second endothermic transition temperature substantially higher than the glass transition temperature.

Abstract: A plastic container having a body portion and a handle portion which extends from the body portion is formed using a pair of mold halves placed into engagement. During the molding process, a surface of the handle portion is provided with a recess in at least one area where the mold halves are in placed into engagement.

Abstract: A container for holding and pouring semi-viscous or viscous liquids is disclosed and is particularly useful for holding and pouring condiments such as ketchup, mayonnaise, mustard, relish or semi-viscous liquids such as salad dressing. The container includes an integrally molded body having a neck finish defining a generally cylindrical opening and being adapted to secure a lid to the container. At least one shaped pour guide is formed by the body below the neck finish for controlling and directing the flow of liquids out of the container in at least one selectable direction. In an embodiment, the container includes a plurality of shaped pour guides formed by the neck of the container and being spaced equidistantly about a circumference of the neck finish and opening of the container.

Abstract: A label pickup mechanism for an in-mold blow molding machine has a rotating magazine system which allows the captive stack of labels to rotate about a center point by sliding on a circular track of a radius common to the base plate of the label magazine and a front plate carried in the label support apparatus. Such rotation prevents the label stack to lose its coordinate position while trying to address label askewness. The label stack is kept compressed against retaining tabs by using label pushers.

Abstract: A vacuum conveyor made up of a plenum and a moving plastic chain with attached buckets shaped to guide and accept and emerging molded article which travelling at zero relative velocity operates as a picker device for a blow molding machine of the type having a rotating mold wheel.
