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.
