    摘要： Disclosed herein are methods and systems for co-extruding multiple polymeric material flow streams into a mold cavity to produce a molded plastic article. At least one interior core stream of a first polymeric material is surrounded by inner and outer streams of at least one other polymeric material. The interior core stream serves as an interior layer of a resultant molded plastic article while the inner and outer streams serve as inner and outer layers, respectively, of the resultant plastic article. The interior core stream is selectively directed to flow into or past a downstream branch channel in a mold cavity. The downstream branch channel branches from a primary channel in the mold cavity at a branch junction. The branch channel defines a protrusion portion of the resultant molded plastic article. The leading edge of the interior core stream is selectively controlled in the branch channel to position the leading edge at or near to the terminal end of the branch channel without having the leading edge of the interior core stream breakthrough a flow-front of the inner and outer streams. The resultant molded plastic article includes an interior layer formed of the first polymeric material that extends into, through and to a distal end of the protrusion while still being encased by inner and outer layers formed from the inner and outer flow streams.

    摘要： A blow mold assembly comprises removable neck insert mold components for forming features of a container for engaging a removable container closure and manually operable retention devices for releasably retaining the neck insert mold components with mating mold components of the mold assembly. Advantageously, each manually operable retention device comprises a clamp mechanism comprising a lever arm and clamp arm arranged so that the clamp arm is rotated between a release position and a clamp position by manual operation of the lever arm and the clamp mechanism is effective to resist forces acting on the clamp arm to rotate the clamp arm to the release position when the clamp arm is in the clamp position. Each manually operable retention device is retained with an associated mating mold component when a neck insert mold component is removed from or installed to the mold assembly.

    摘要： A flex plate for a guiding device of an injection molding machine includes a body extending between a front surface, a back surface, a top surface, and a bottom surface. A plurality of through holes extend between the top surface and the bottom surface for aligning the flex plate with a foot of the guiding device, and a plurality of guide shoe holes formed in the bottom surface of the flex plate couple the flex plate to a guide shoe of the guiding device. A front plate couples the front surface of the flex plate to the foot of the guiding device, and a plurality of slots define a central portion of the flex plate. The central portion of the flex plate is elastically deformable about a torsional axis and can pivot relative to the guide shoe and foot of the guiding device.

    摘要： A container may comprise a spout, a base portion, and an ovular sidewall extending away from the base portion to the spout. The ovular sidewall comprises a vertical portion, a top transition region, and a top region extending from the top transition region to the spout. The top region comprises at least two discrete linear sections having different slopes between the top transition region and the spout. Moreover, the base portion of the container defines a support surface on which the container rests, a base channel extending across the diameter of the container, and an inset concave panel aligned with a center of the container. The container additionally comprises a handle portion defining a complex-curved face surface interrupting the top transition region and the top region, and a handle extending from a bottom portion of the face surface to a top portion of the face surface.

    摘要： A co-injection nozzle is disclosed that includes a combining means configured to reduce shear heating and create a more even shear heating profile in core and skin material flow streams. The combining means is configured to reduce shear heating peaks and valleys in core and skin material flow streams as the streams flow between annular channels of the combining means during a mold filling process.
