ABSTRACT:
A neck mold for a glass champagne bottle forming system for forming bottles on the well-known I.S. forming machine is made of two matching halves that form the transfer bead and lower portion of the neck of the bottle mates with an annular, one-piece guide ring carried by the neck ring. The annular guide ring has a relatively sharp edge that matches with the plunger that forms the interior of the bottle finish and also has a flat surface, adjacent the sharp edge, that extends at a 25.degree. angle with the horizontal and forms a planar sloping surface on the inner, upper surface of the bottle with the planar surface being joined to a flat, generally horizontal surface that extends to a curved surface that in turn extends over the top of the bottle finish to an outer annular line where the guide and neck ring mold meet. The resulting bottle produced is one which does not require fire polishing to remove any mold match lines or beads that might interfere with proper sealing of the corks.
