<p>The invention provides an apparatus and method for blow molding large containers previously considered too large to manufacture on small bottle rotary type blow-molding machines. The invention discloses a blow mold (12) for use in a rotary blow-molding machine which comprises at least two blow mold segments (22,24) which cooperatively define an interior container shaped cavity and a cooling circuit incorporated within each of the blow mold segments. In use coolant fluid is circulated through the cooling circuit to control the temperature of the mold. The invention also claims a method of making a plastic container. A preform is positioned in the above mold and inflated to form the container. Coolant fluid is then circulated through the cooling circuit, after which the container is removed from the mold.</p> |
