Abstract: An angular interlock for a swivel feature formed using injection molding techniques is described herein. In one exemplary embodiment, the swivel feature is used for a conduit for delivering breathing therapy to a patient, and includes an outer swivel component and an inner swivel component formed using a two-shot molding technique. The outer swivel component is formed first out of a material, such as polycarbonate, having a low shrink rate, whereas the inner swivel component is formed of a material, such as polypropylene, having a high shrink rate. The material for the inner swivel component is injected into the formed outer swivel component and allowed to cool, creating a clearance. The outer swivel component includes an angular interlock protrusion that allows the inner swivel component to be formed without creating an interface about the angular interlock protrusion, which typically occurs with standard rectangular interlocks.
