US 8,283,007 B2 · Blow molded receptacle and system for making same

Abstract

A system for making blow molded receptacles is disclosed generally comprising two mold portions that, when positioned adjacent each other, at least partially enclose a cavity defined by a molding surface, against which the walls of a blow molded receptacle are blown. One of the portions is a mold core, which has a base surface and a raised portion extending out from the base surface into the cavity. The raised portion has an outer surface and a side surface, which results in a corresponding, inner sidewall on the blow-molded receptacle. The raised portion houses a punch partly disposed in an opening in the side surface for punching a hole in the sidewall. In some embodiments, the side surface is substantially perpendicular to the seal between the two mold portions, and an actuator displaces the punch in a direction substantially parallel to the seam.

A blow molded receptacle, comprising:

a double wall, blow molded body, said body having first and second sides at least partially enclosing a cavity therebetween;
and
a lid portion integrally formed with said body;
wherein said second side includes an unraised portion and a raised portion extending transversely from said unraised portion, said raised portion having an outer wall and a sidewall perpendicular to said first side and said outer wall, such that said cavity is wider between said outer wall and said first side than between said unraised portion and said first side;
wherein said sidewall has a hole therethrough;
and
wherein said lid portion has first and second hinged sections, and wherein, when said lid portion is moved from an open position to a closed position, said second hinged section pivots away from a common plane with said first hinged section to contact said sidewall, such that said lid portion covers said sidewall and hole when in a closed position.
