ABSTRACT:
A plastic molded article including a body is provided. The body includes a first surface thereof and a second surface thereof. The second surface is spaced from the first surface. The body defines a first cavity extending inwardly from the first surface and a second cavity extending inwardly from the second surface. The first cavity overlaps the second cavity so as to form an aperture extending at least partially through the plastic molded article. The body further defines a recess extending inwardly from at least one of the first cavity and the second cavity at a location where the first cavity overlaps the second cavity so as to accommodate flash which may be formed during the molding process of the plastic molded article.
