Abstract
A blow slot equipped core rod assembly which incorporates a porous metal wall portion. Internal conduit means in the assembly permit a fluid (such as air, or the like) to be supplied to said blow slot (when open) and to such porous metal wall portion under superatmospheric or under subatmospheric pressure. The core rod is particularly useful in the manufacture of multilayered thermoplastic containers by injection blow molding procedures.
