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 (M.sub.1, M.sub.2) having an inclined cavity (20, 404) to be stretched by a stretching rod (17) during an air-blow operation or that a curved parison (405, 512) is set in the blow mold (M.sub.1, M.sub.2) to be stretched by air-blow. The parison is curved or deformed by a defining mold (431, 711) or a pushing bar (514).
