Abstract:
A method of molding a plastic container body having at least one grip recess includes providing a mold assembly having an internal projection that is constructed and arranged to form the grip recess. A low friction surface is provided on at least a portion of the projection in order to reduce friction between the formable plastic material and the projection during the molding process. The low friction surface permits the formable plastic material to stretch with less resistance before it solidifies to the point where additional stretching is not possible. As a result, molding of features that provide resistance to material distribution during molding, such as deep grip recesses, is enabled.
