ABSTRACT:
A storage container is formed by joining together the sides and top of a pair of matched laminated flat sheets. The bottom portions are joined together adjacent the sides, but the center is sealed along the sealing surfaces of a tube connector assembly, the connector portion being in the form of a parallel pipe head, the center of which is enclosed a tube. The tube extends through the connector and projects outwardly therefrom to provide a closable access path for filling and draining the container. The projected portion of said tube is corrugated.
A sleeve is formed along the top edge of the sealed top portion of sealed container and a stiffener rod is installed in the sleeve to provide a more stable structure for handling when the container is filled. Below the sleeve and horizontally centered is a hook mounting aperture for holding the container in the drain position. Disposed symmetrically on opposite sides of said hook mounting aperture are a pair of gripping apertures which facilitate handling of the container. At the bottom are a pair of sealed flaps disposed on each side of said tube projection and within each flap is an aperture. These apertures are used to hold a container during the filling cycle.
A shut-off cap is a tubular structure and has a wide section, the interior of which fits over the tube projection and a narrow section. The interior walls of said wide section are corrugated so that a fluid tight fit is obtained when installed on said tube projection. A membrane, which seals the shut-off cap, is formed at the junction of the wide and narrow sections of said shut-off cap. A dust cover is attached by a flexible lead and is designed to fit over a part of the narrow section, thus preventing dust and other contaminants from getting into the narrow tube during storage and transport.
