    摘要： A process for producing a heat- and pressure-resistant polyester bottle, comprising a primary blow-molding step of obtaining a primary molded article by biaxially stretch-blow-molding a preform of a polyester resin, a heat-treating step of obtaining a secondary molded article that is heat-shrunk by heat-treating the primary molded article, and a secondary blow-molding step of obtaining a finally molded article by biaxially stretch-blow-molding the secondary molded article, wherein the primary blow-molding step biaxially stretches the neck portion of the primary molded article to a size nearly the same as the neck portion of the finally molded article, and the heat-treating step does not cause the neck portion of the secondary molded article to be heat-shrunk. The heat- and pressure-resistant polyester bottle has a slender neck portion of the shape of a so-called crane neck and is suited for containing beer without eradicating the impression of the traditional glass-bottled beer, wherein the length of the neck portion is in a range of 10 to 40% of the height of the bottle, the crystallinity of the neck portion is in a range of 20 to 35%, and the crystallinity of the body portion is in a range of 35 to 50%.

    摘要翻译： 一种耐热耐压聚酯瓶的制造方法，其特征在于，包括通过双轴拉伸吹塑成型聚酯树脂的预成型体获得一次成型体的一次吹塑成形工序，获得二次成型体的热处理工序 通过对一次成型体进行热处理而进行热收缩的成型品和二次吹塑成型工序，通过双向拉伸吹塑成型二次成型品得到最终成型品，其中，一次吹塑成形工序双轴拉伸 一次成型体的颈部尺寸与最终成型体的颈部大致相同的尺寸，热处理工序不会使二次成型体的颈部热收缩。 耐热耐压聚酯瓶具有所谓的起重机颈部形状的细长的颈部，并且适合于容纳啤酒而不消除传统的玻璃瓶装啤酒的印象，其中颈部的长度为 在瓶的高度的10〜40％的范围内，颈部的结晶度在20〜35％的范围内，主体部的结晶度在35〜50％的范围内。
