System for creating blow molded case

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.
