    Abstract: In a process for making a multi-chambered container that is lightweight, relatively inexpensive to produce, and that requires less external reinforcement against flexure than conventional multi-chambered containers do, a parison is heated and inflated to form the container. Further, first and second pinched-in areas are fashioned in the sidewall of the container. The first pinched-in area includes first and second wall portions that extend inwardly toward an interior of the main body of the container, and a first end wall portion connecting the first and second wall portions. The second pinched-in area includes third and fourth wall portions that extend inwardly toward an interior of the main body, and a second end wall portion connecting the third and fourth wall portions. The first end wall portion is joined to said second end wall portion so as to define separate compartments within said main body, and wherein the first end wall portion is laterally offset from the second end wall portion, whereby the flexibility of the main body about the joint of the first and second wall portions is minimized. In the next step, the container is cooled.

    Abstract translation: 在制造多层容器的过程中,比常规多室容器更轻便,相对便宜的制造方法,并且比起传统的多室容器要求较少的外部加固,使型坯被加热并膨胀以形成容器。 此外,第一和第二夹入区域形成在容器的侧壁中。 第一夹持区域包括朝向容器的主体内部向内延伸的第一壁部分和第二壁部分,以及连接第一和第二壁部分的第一端壁部分。 第二夹持区域包括向内延伸到主体内部的第三和第四壁部分,以及连接第三和第四壁部分的第二端壁部分。 第一端壁部分连接到所述第二端壁部分,以在所述主体内限定分开的隔室,并且其中第一端壁部分从第二端壁部分侧向偏移,由此主体围绕 第一和第二壁部分的接头最小化。 在下一步骤中,容器被冷却。
