ABSTRACT:
Disclosed is a receptacle for transporting, storing and dispensing flowable materials. The receptacle has an outer covering formed from a single sheet of material wrapped to form a cylinder with its edges attached together in an overlapping arrangement by double-sided adhesive tape. A polyester filament is positioned inside the outer protective cover in the form of a helix. The filament is adhesively attached between the interior of the outer cover and the exterior of an inner bag. A support sling is provided of polyester webbing material having an inner ring for supporting the bottom of the receptacle and a larger outer ring. Three loops of webbing material are attached to the inner and outer rings in a spaced circumferential arrangement. The loops are of sufficient length to extend up between the outer cover and interior bag and are adhesively attached therebetween. The inner bag has inner and outer walls formed from a single sheet of polyethylene material wrapped in a spiral with the edges of the sheet attached by double-sided adhesive tape to a dividing portion on the sheet material. The outer wall is attached by non-curing mastic material. The outer wall is attached by non-curing mastic material to the interior of the outer protective covering. The inner bag is closed at its upper and lower ends by removable wire ties and the lower end extends through the center of the smaller ring of the sling.
