Stretch blow molding method for manufacturing an expanded bottle, a parison deforming mold for deforming or curving a stretch parison, and a stretch blow molded bottle

摘要

A stretched bottle (1) has an inclined mouth portion (31). The bottle (1) is formed in a manner that a straight parison is set in a blow mold (M₁, M₂) having an inclined cavity (20, 404) to be streched by a stretching rod (17) during an air-blow operation or that a curved parison (405, 512) is set in the blow mold (M₁, M₂) to be stretched by air -blow. The parison is curved or deformed by a deforming mold (431, 711) or a pushing bar (514).
