Abstract:
A method of making a container preform includes providing a mold core having at least one surface recess in the form of negative-mold indicia, and molding a preform around the core such that the preform has internal raised indicia formed by the at least one recess in the core. The preform preferably subsequently is blow-molded to form a container having the raised indicia on an inside surface of the container.
