Abstract
A substantially cylindrical plastic parison is expanded within a blow mold against the internal walls thereof to form a plastic drinking vessel with a rim having substantially smooth inner and outer surfaces thereon. The inner surface is formed by a reciprocating cutter head assembly including an annular cutter blade with an outside diameter slightly less than the inside diameter of wall surfaces of the blow mold adjacent to a peripheral recess in the blow mold in which an external bead on the rim is formed. The cutter blade and cutter head assembly form a dome-shaped top in response to expansion of the parison. When the cutter blade is retracted axially from the blow mold the dome-shaped top is severed from the vessel. In an alternative embodiment the vessel and a partially severed dome-shaped top are removed as an integral unit from the blow mold and the dome-shaped top is then completely severed from the vessel utilizing a rotary cutter blade.
