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.

A co-injected molded multi-layer article has inner and outer layers, an interior layer contained within the inner and outer layers and a surface portion to which a closure or other component may be heat-sealed. The article is molded by co-injecting the inner, outer and interior layer materials into a mold cavity of a mold. The interior layer material is caused to flow along a steam line offset from the zero velocity gradient of the combined material flow and biased toward a material flow for forming an outer wall of the multi-layer article. The resultant molded multi-layer article contains an interior layer located in a heat sealable region that avoids a breach or failure during a heat seal operation to seal an opening of the molded article.

Disclosed herein are methods and systems for the preparation of a co-injection molded multilayer plastic article. Some methods include co-extruding a combined polymeric stream having an interior core stream encased by an inner stream and an outer stream. One or more pulses in a thickness of the interior core stream create portions of an edge of the outer flow stream flowing along different streamlines. A first portion of an outer edge of the interior core stream flows beyond a second portion of the outer edge thereby forming one or more cohesion members that physically interlock the interior layer with the inner layer, with the outer layer or with both. Some embodiments reduce or eliminate a need for addition of an adhesive in the composite stream to prevent delamination of layers of the resulting multilayer plastic article. In some embodiments, cohesion members may be employed to produce a desired cosmetic effect in a resulting article.

Abrégé

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.

Second actuators are advantageously fluid (hydraulic or pneumatic) operated to supplement force provided by an electrically operated primary actuator when the ejector mechanism is driven to advance ejector members into cavities of a mold assembly. The second actuators may be enabled to be operated during automatically controlled execution of a machine cycle of operation and may be operated in response to operator selections when machine operation is controlled manually.

A molded multi-layer article has an interior layer contained within inner and outer layers. The article is molded by co-injecting the inner, outer, and interior layer materials into a mold defining a cavity. The interior layer material is caused to flow along a steam line offset from the zero velocity gradient of the combined material flow in a manner so that the interior layer material flow stream does not flow along or cross the zero velocity gradient yet has a greater flow velocity than the average flow velocity of the combined flow front. These methods and apparatus can mold four or more multilayer articles at once, each having an interior layer extending throughout 95% or more of the sealable portion of the article. The interior layer of a resultant article can extend throughout 99% or more of the sealable portion of the article.

A co-injected molded multi-layer article (100) has inner (190) and outer layers (130, 132), an interior layer (150) contained within the inner and outer layers (130, 132) and a surface portion to which a closure or other component (120) may be heat-sealed. The article is molded by co-injecting the inner, outer and interior layer materials into a mold cavity of a mold. The interior layer material is caused to flow along a steam line offset from the zero velocity gradient of the combined material flow and biased toward a material flow for forming an outer wall of the multi- layer article. The resultant molded multi- layer article contains an interior layer located in a heat sealable region (180) that avoids a breach or failure during a heat seal operation to seal an opening (107) of the molded article.

Plastic container (110), including a side wall (120) and a flexible portion (132) of a base (130). The flexible portion of the base deflects when the sealed plastic container experiences a differential pressure. The deflection of the flexible portion of the base acts to change the internal volume of the container and thereby reduce the differential pressure. The container is a retortable container. The container may be injection-molded with inner and outer plastic layers (460,462) and a core layer (464) between the inner and outer plastic layers.

A method to predict the remaining useful life of a plasticizing screw for an injection molding machine is provided. The method comprises: creating an energy-pressure ratio distribution estimate for normal operation of the screw for a mold; creating a temporally local energy-pressure ratio distribution estimate from real time data for the screw for the mold; comparing the local distribution with the distribution for normal operation; and generating an alert if the comparison of the two distributions predicts that the remaining useful life is negligible.

An apparatus for injection molding comprises an injection unit comprising a plunger, the plunger being translated with accumulation of plasticized material in preparation for injection and being advanced to inject the accumulated plasticized material into mold cavities. At least one electric motor is engaged with the plunger to resist translation as melt is accumulated and to inject plasticized material into the mold cavities. At least one hydraulic actuator selectably operates the plunger during a pack and hold interval to supply supplemental force when force supplied by the electric motors is limited to maintain the operation of the motors within the applicable continuous duty rating thereof. The electric motors are advantageously selectably operatively engaged with the plunger to inject plasticized material into the mold cavities and the hydraulic actuators are operated to inject plasticized material into the mold cavities when the motors are not engaged therefore.

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.
