Abstract
A multi-purpose fitting system includes a container having an inner tank and an outer tank made of a plastic material. An aperture is provided at the top of the container in which a multi-purpose fitting is provided. The fitting includes a close-off fitting base having a flange which is permanently attached to an outer surface of the inner tank. A close-off skirt made of a plastics material rest on the flange and extends beyond the flange to additionally rest on the outer tank. This skirt is securely attached to an outer surface of the outer tank such as by a continuous weld which provides a seal between the skirt and outer tank. A close-off ring is threadably received on a threaded upper portion of the close-off fitting base to press the skirt against the flange. A fitting member is threadably received in an interior threaded aperture of the close-off fitting base as appropriate. A close-off cap preferably covers the close-off ring, and a suitable seal is provided between the close-off cap and the close-off skirt. The skirt also preferably includes a raised circumferential rib positioned so that the close-off cap has a depending rib which fits snuggly between the close-off ring and the raised rib. The closed-off cap is also preferably designed to be cut at stepped rings thereof to form an opening concentric with the interior threaded aperture such that a fitting member including a pipe passes through the opening and is sealed by wrap-around heat shrink plastic member. The fitting member can also preferably be a hook portion by which the container may be lifted.
