Abstract:
1. A container and supporting pallet for bulk handling of fluid which minimizes shock and abrasion on a fluid transporting bag within the container wherein the container elements are shaped to maximize the quantity of fluid containable therein and the container elements are structured to withstand the pressure exerted by such fluid, comprising: a wooden pallet structure having a flat rectangular deck with narrow wooden framing members secured on a top surface along four opposed sides, a plurality of elongate rectangular wooden skids having a top edge secured to the underside of said deck in parallel equally spaced relation, and a plurality of horizontally disposed wooden bottom boards secured to a bottom edge of said skids and extending transversely relative thereto to provide openings on four sides of said pallet structure for receiving forks of a fork lift; a generally rectangular flexible outer liner/bag supported on said deck formed of double wall water impervious internal woven plastic material having four side walls, an open top end, and a bottom wall, the double walls of said side walls secured together at the corners to form open top end pockets; four generally rectangular rigid wooden stiffener panels, each having a bottom end, a top end and longitudinal lateral sides, and each removably received in a respective said pocket of said outer liner/bag and disposed in a generally vertical orientation, said stiffener panels having a width less than the width of said pockets such that their said lateral sides are spaced a distance apart and are not joined together so as to form non-structural floating corners defined only by the corners of said outer liner; a flexible generally cubical multiple ply inner bag formed of liquid impervious material disposed inside of said outer liner/bag, said inner bag having four side walls, a top wall, and a bottom wall defining an interior, an internally threaded bung having a bottom flange sealed around an opening in said inner bag top wall, a second flange of smaller diameter spaced a short distance above said bottom flange, at least two laterally opposed flat surfaces extending between said bottom flange and said second flange, a neck portion extending upwardly from said second flange, a passageway in communication with said inner bag interior for permitting fluid passage into or out of said bag interior through said inner bag top wall, seal means at an upper end, and a removable closure member threadedly and sealingly engaged in said passageway; an internally threaded valve fitment on one side wall of said inner bag near a bottom end for receiving a discharge valve, said valve fitment sealed to said inner bag such that the plies of said inner bag are not penetrated, and a removable closure member threadedly engaged in said valve fitment, said closure member being removed and said plies of said inner bag being penetrated upon subsequent attachment of a dispensing valve having a cutting element for controlled dispensing of fluid from said inner bag; a flat generally rectangular wooden top panel having a central hole therethrough and narrow wooden framing members secured to an underside surface along four opposed sides, said top panel supported on said stiffener panels top ends with said framing members disposed outward of said stiffener panels top ends; a cover member for covering said central hole in said top panel; and elongate strapping bands tightly secured beneath the underside of said pallet deck, said skids, and over said top panel and said cover member to retain said stiffener panels in position and secure said pallet, said inner liner/bag, said stiffener panels, and said top panel together as a tamper-resistant stackable unit with said inner bag and its said bung and valve fitment disposed entirely within said inner bag or liner.
