    • A thin-walled tubular container and a mold for making it is disclosed. The container defines a head portion with access means to the contents of the container, and a tail portion defining a sealed line in the tail portion, joining sides of the container into a sealed end with a flat plastic piece being formed integral with the sealed line and extending away therefrom. In accordance with this invention, a pair of spaced rod members are formed as an integral part of the flat, plastic piece, the rod members extending transversely of the longitudinal axis of the container. The flat plastic piece also defines a portion thereof between the rod members which is thinner than any remainder of the plastic piece spaced from the rod members. Accordingly, the rod members and intermediate portion therebetween provide an improved and stronger tail seal. A novel method for making such containers is also shown.
    • 公开了一种薄壁管状容器和用于制造它的模具。 容器限定了具有到容器内容物的进入装置的头部和在尾部中限定密封线的尾部,将容器的侧面连接成密封端,扁平塑料件与密封线形成一体 并从中延伸出来。 根据本发明,一对隔开的杆构件形成为平的塑料件的整体部分,杆构件横向于容器的纵向轴线延伸。 扁平塑料件还限定其在杆构件之间的一部分,其比与杆构件间隔开的塑料件的任何其余部分更薄。 因此,杆构件和它们之间的中间部分提供了改进和更强的尾部密封。 还示出了制造这种容器的新颖方法。
