ABSTRACT:
A method of making a thin-walled tubular container. 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.
