PRIMARY MOLD OF BOTTLE BODY WITH HANDLE AND METHOD OF MANUFACTURING BOTTLE BODY WITH HANDLE

摘要

A primary molded bottle body is blow molded with a bottom and tubular lower body blank portion suspended and continuously provided from the bottom of an upper body portion. The upper body portion comprises a mouth tube continuously provided through a shoulder portion to the top end of a body wall provided at the back portion thereof with a handle piece. Only the lower body blank portion of primary molded bottle body is blow molded by biaxial stretching into a lower body portion to obtain a bottle body, so that a large sized bottle body with a handle having the substantially equal strength to a biaxially stretched blow-molded bottle can be obtained.
