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.

What is claimed is: 1. An apparatus for creating the base portion of a blow molded case having inner and outer case walls, comprising; a mold having first and second mold portions that, when located adjacent each other along a seam, at least partially enclose at least one cavity having a cavity surface; wherein said cavity surface includes outer and inner case wall portions, against which the outer and inner walls of the base portion of the case are blown, respectively, during blow-molding; a punch having a punching surface, wherein, when said punch is in an unactivated position, the outer case wall portion of said cavity surface includes said punching surface and, when said punch is in an activated position, said punch is extended past the outer wall of the case and into said cavity such that a hole is created in the outer wall of the case; wherein the outer case wall portion of said cavity surface includes a section substantially perpendicular to the seam, against which a sidewall of the outer wall of the base portion of the case is blown during blow molding; and wherein said substantially perpendicular section includes said punching surface when said punch is in an unactivated position, and said punching surface is extended past the sidewall when said punch is in an activated position. 2. The apparatus of claim 1, wherein said punching surface corresponds to at least part of the outline of an object to be inserted into the hole. 3. The apparatus of claim 1, wherein said substantially perpendicular section of the outer case wall portion of said cavity surface has a non-planar planar area. 4. The apparatus of claim 1, wherein said substantially perpendicular section of the outer case wall portion of said cavity surface includes a protuberance extending into said cavity adjacent said punching surface when said punch is in an unactivated position, such that a recess is formed in an outer surface of the outer case wall during blow molding. 5. The apparatus of claim 1, wherein, when said punch is in a third position, said punching surface is extended past said cavity surface to a lesser extent than when in the activated position such that a wall member is formed around part of said punch during blow molding. 6. The apparatus of claim 1, wherein said punching surface includes a protuberance extending outwardly therefrom such that a recess is formed in an outer surface of the outer case wall during blow molding. 7. The apparatus of claim 1, wherein the outer wall portion of said cavity surface includes a protuberance extending into said cavity substantially perpendicular to the seam and positioned relative to said punching surface when said punch is in an unactivated position at a distance corresponding to the length of an object to be inserted into the hole, such that movement of the object into said cavity is limited thereby. 8. The blow molded case of claim 7, wherein the outer wall portion of said cavity surface has a plurality of ribs for creating corresponding ribs on an inner surface face of the outer wall of the base portion of the case for engaging a bottom surface of the object to be inserted into the hole. 9. An apparatus for creating the base portion of a blow molded case having inner and outer case walls, comprising; a mold having first and second mold portions that, when located adjacent each other along a seam, at least partially enclose at least one cavity having a cavity surface; wherein said cavity surface includes outer and inner case wall portions, against which the outer and inner walls of the base portion of the case are blown, respectively, during blow-molding; and a punch having a punching surface, wherein, when said punch is in an unactivated position, the outer case wall portion of said cavity surface includes said punching surface and, when said punch is in an activated position, said punch is extended past the outer wall of the case and into said cavity such that a hole is created in the outer wall of the case; and wherein the outer wall portion of said cavity surface includes a protuberance extending into said cavity substantially perpendicular to a direction of travel of the punch as the punch moves from the unactivated position to the activated position. 10. The apparatus of claim 9, wherein the outer wall portion of said cavity surface has a plurality of ribs for creating corresponding ribs on an inner surface of the outer wall of the base portion of the case for engaging a bottom surface of an object to be inserted into the hole.
