Plastic blow-molded container (20) having at least one and preferably a plurality of penetrable wall portions (22) or sites which are sufficiently thin to permit piercing by a needle (41), spike or the like without coring or fragmenting, and also having a thicker recessed wall portion (32) adjacent to each penetrable wall portion. Each penetrable wall portion (22) is formed during the blow-molding process by expanding the plastic parison (24) over a projection (28) in the mold cavity (26) and into an adjacent recess (30) in the cavity (26). The thin penetrable portion (22) of the container (20) is formed within the mold recess (30) and the thicker recessed portion (32) of the container (20) is formed by the mold projection (28). With a plurality of penetrable sites (22), liquid may be withdrawn or added through a needle (41) or spike inserted through one site, while displacement air is vented through a needle or the like inserted through another site. The sites (22) may be spaced sufficiently close together to permit sterilization, for example by swabbing, in one motion. |
