<p>The present invention relates to a hollow transparent polypropylene vessel for sterilization and an apparatus for manufacturing the same. The method for manufacturing the hollow transparent polypropylene vessel for sterilization according to the present invention is characterized by comprising the steps of: forming a preform by melting a polypropylene resin in an injection molding machine and injection molding in a mold; cooling the preform; stabilizing the cooled preform; heating the stabilized preform by passing through a heating zone in which first to eighth heat lamps are installed; and blowing the heated preform. Accordingly, a high transparency hollow vessel is manufactured without adding a nucleating agent, thereby being used as a next-generation drug storage vessel which has the light weight, is easily recycled, and requires low costs.</p> |
