The present invention addresses the problem of providing a method for manufacturing bottles with a narrow mouth without creating a bead, easily and at low cost, when manufacturing a plurality of types of bottles having the same body shape with different mouth diameters. A plurality of types of mouth molds corresponding to the shapes of the mouth of the glass bottles to be formed are prepared. Also prepared are a plurality of types of neck moldings having a neck molding face corresponding to the shapes of the neck of the glass bottles to be formed in a rough mold and a finish mold which have a two-part cylindrical shape on which a half-doughnut-shaped notch is formed on the upper edge of each half. The half-doughnut-plate-shaped neck moldings, the inner peripheral surfaces of which are the neck molding face, are removably attached to the notches. The present invention solves the above problem by forming glass bottles using a mouth mold selected corresponding to the shape of the mouth and neck of the glass bottle to be formed as well as a rough mold and a finish mold to which the neck molding is attached. |
