Abstract: A method and apparatus for blow molding a case for housing an object, such as a tool, is disclosed generally comprising first and second mold portions located adjacent each other to create separate cavities for forming base and lid portions of a case and a punch for each portion corresponding to the outline of an object. In certain embodiments, the punch protrudes into the cavity during blow molding to create a sidewall to facilitate a press fit. In some embodiments, additional punches and/or recesses are provided to produce additional apertures or flanges in the walls of the tool case.

Abstract: A blow molded case is disclosed generally comprising a double wall, blow molded base portion having inner and outer case walls, and a lid portion connected to the base portion such that the lid, when in a closed position, at least partly covers the inner case wall of the base portion, which accommodates a first object. The outer wall of the base portion has a hole for receiving a second object, such as a drawer or other receptacle. In certain embodiments, the hole is a punched hole, created by extending a punch through a sidewall of the base portion substantially perpendicular to the parting line thereof. In certain embodiments, the sidewall is non-planar, and in some embodiments, the sidewall includes a recess adjacent the hole for easily gripping the second object.

Abstract: A method and apparatus for blow molding a case for housing an object, such as a tool, is disclosed generally comprising first and second mold portions located adjacent each other to create separate cavities for forming base and lid portions of a case. The second mold surface includes a protuberance for creating a protrusion on an outer wall of the case during blow molding, which serves to restrain the movement of an object that is received in a hole in the corresponding inner wall of the case. In certain embodiments, the protrusion corresponds to at least part of the outline of the object or an aperture in the object. In some embodiments, the protrusion is positioned to engage an edge of the object to prevent movement.
