    • The blow-molded container of this invention comprises an outer layer (2) of' a synthetic resin, which forms the outer shell of' a finite shape; an inner layer (3) of a flexible synthetic resin, which is peelably laminated with the outer layer (2) and forms an inner bag; and a pair of' adhered zones (4) of' a vertical strip type, which is formed axisymmetrically on the central axis of container (1) to adhere and fix the outer layer (2) and the inner layer (3) over the entire height and is located so as to avoid the positions of air introduction ports (9) that have been provided in the outer layer (2) to introduce air into the void between the outer layer (2) and the inner layer (3) In this configuration, a pair of adhered zones (4) is disposed at positions opposite to each other and is separated by a parting line (5). The lower ends of both adhered zones (4) are disposed at the partly or wholly end-to-end position facing each other on the bottom seal formed when the bottom portion is pressed flat with the pinch-off of' a blow mold. Because of' this end-to-end facing position of' the lower ends, the bottom seal has a full mechanical strength. Thus, there is provided a container of the delaminated type capable of molding by means of an ordinary mold and having high manufacturing efficiency.
    • 本发明的吹塑容器包括:“合成树脂外层”,其形成有限形状的外壳; 柔性合成树脂的内层(3),其与外层(2)可剥离地层压并形成内袋; 以及一对“垂直带状”的粘附区域(4),其在容器(1)的中心轴线上轴对称地形成,以将外层(2)和内层(​​3)固定在整个 并且被设置为避免设置在外层(2)中的空气引入口(9)的位置,以将空气引入到外层(2)和内层(​​3)之间的空隙中。在这 配置时,一对粘接区域(4)设置在彼此相对的位置处并由分型线(5)分开。 两个粘合区域(4)的下端设置在底部密封件上形成的部分或全部端对端位置,当底部被“吹塑”模具夹紧时被压扁。 由于底端“端到端的位置”,底部密封具有完全的机械强度。 因此,提供了能够通过普通模具成型并具有高制造效率的分层型容器。
