Abstract:

A system for coinjection molding a multi-layer container includes an injection molding apparatus, a camera, and a controller. The injection molding apparatus is configured to coinject a plurality of polymeric materials into a mold cavity to form a multi-layer container including an inner layer, an outer layer, and a barrier layer located between the inner layer and the outer layer. The camera is configured to capture an image indicating a location of the barrier layer within the multi-layer container. The controller is configured to monitor the location of the barrier layer using the image captured by the camera, compare the location of the barrier layer to a threshold location, and provide a control signal to the injection molding apparatus based on the location of the barrier layer relative to the threshold location.

Abstract:

A method for manufacturing an injection molded container includes operating an injection molding apparatus to inject one or more polymeric materials into a mold cavity to form a container. The container includes an energy director ring protruding from an inside surface of the container and extending circumferentially along the inside surface. The method includes welding a filter onto the inside surface by applying a welding force to the inside surface. The energy director ring causes the welding force to be concentrated at a location of the energy director ring, thereby forming a circumferential weld that secures the filter to the inside surface the location of the energy director ring.

International Classification:

B29C 45/26
B29C 45/76
B29C 45/16

Abstract:

A coinjection molded multi-layer container includes an inner layer, an outer layer, and a barrier layer. The inner layer includes a first polymeric material and forms an inside surface of the container. The outer layer includes the first polymeric material and forms an outside surface of the container. The barrier layer is located between the inner layer and the outer layer and includes a second polymeric material less permeable to gas than the first polymeric material. The barrier layer is biased toward the inside surface or the outside surface such that the inner layer and the outer layer have different thicknesses.
