摘要:
A method and apparatus for blow molding a case (10) for housing an object, such as a tool, is disclosed generally comprising first and second mold (52,54) portions located adjacent each other to create separate cavities for forming base (24) and lid (34) portions of a case (10) 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.

摘要:
A blow molded case (10) is disclosed generally comprising a double wall, blow molded base portion (12) having inner and outer case walls, and a lid portion (14) connected to the base portion such that the lid, when in a closed position, at least partly covers the inner case wall (22) of the base portion, which accommodates a first object. The outer wall (24) of the base portion has a hole (20) 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.
