<p>A plastic blow-molded container is disclosed having at least one and preferably a plurality of penetrable wall portions or sites which are sufficiently thin to permit piercing by a needle, spike or the like without coring or fragmenting, and also having a thicker recessed wall portion adjacent to each penetrable wall portion. Each penetrable wall 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. With a plurality of penetrable sites, liquid may be withdrawn or added through a needle or spike inserted through one site, while displacement air is vented through a needle or the like inserted through another site. The sites may be spaced sufficiently close together to permit sterilization, for example by swabbing, in one motion.</p> |
