ABSTRACT:
This invention relates to a composite container for liquids, such as oil, including a generally tubular vertically arranged fibrous body wall, a flexible impervious membrane-type closure member closing the bottom end of the body wall, and an outer support cap for supporting in protective relation the membrane closure member. The end closure member includes an annular peripheral flange portion that is arranged concentrically within, and is bonded to the inner surface of, the fibrous body wall, which flange portion extends longitudinally upwardly of the container from a central disk portion that extends transversely across the body wall adjacent the lower end thereof. The support cap includes a central disk portion that extends in supporting relation beneath the central portion of the membrane closure member, and a peripheral flange portion that extends concentrically about, and is bonded to the external surface of, the fibrous body wall.
