Abstract
A plastic blow-molded container is disclosed having a penetrable wall portion or site which is sufficiently thin to permit piercing by a needle, spike or the like without coring or fragmenting, and a thicker recessed wall portion adjacent to the penetrable portion. The penetrable portion is formed during the blow-molding process by expanding the plastic parison over a projection in the mold cavity and into an adjacent recess in the cavity. The thin penetrable portion of the container is formed within the mold recess and the thicker recessed portion of the container is formed by the mold projection.
