Patent ID: 7182905

Claim:
A method of creating a blow molded article having a retaining feature comprising the steps of: providing a first mold half having a protrusion extending from an inner surface thereof, the protrusion having a protuberance extending therefrom in a direction generally parallel to the inner surface, the protuberance having a generally planar face and being spaced apart from the inner surface so as to define a space therebetween; providing a second mold half having a generally planar side wall generally parallel to the generally planar face of the protuberance; and bringing the first mold half and the second mold half together with a molten parison disposed therebetween such that the generally planar face of the protuberance of the first mold half abuts the generally planar side wall of the second mold half and such that the parison flows into a cavity defined by the space between the protuberance and the inner surface of the first mold half and the generally planar side wall of the second mold half in order to form a wall having an integrally molded hole separated from an edge thereof by a thin bridge of material.
