TRANSPORT AND STORAGE CONTAINER FOR LIQUIDS

Abstract

For fastening the top wall (4) of the inner container (2) at the protective cover (11) of a transport container, which includes an outer casing of vertical and horizontal grate rods of metal or composed of sheet metal, bolts (31) of synthetic material or metal are inserted through fastening eyes (26) of the inner container' (2) which protrude upwardly above the cover (11). By fastening the top wall (4) of the inner container (2) of synthetic material to the protective cover (11) of the transport container, it is made impossible that the top wall (4) with the filler connection is lowered under the influence of outer or inner forces, for example, due to a negative pressure building up when a hot liquid cools in the inner container.

Specification Title: Transport and Storage Container for Liquids The invention relates to transport and storage containers for 1iquids, with a pallet-1ike under frame, an inner container of synthetic material with four side walls, a bottom wall and a top wail, and a closeable filler connection integrally formed on the top wall, and an outlet connection with a discharge fitting integrally formed in a lower portion of a side wall, an outer casing composed of vertical and horizontal grate rods or constructed as a sheet metal casing, and a removable protective cover of sheet metal or synthetic material fastened to the outer casing and provided with a central entry opening to the filler connection of the inner container which is closeable by a screw cap {DE 38 19 911 C2). When these known transport and storage containers are filled with hot liquids and when the liquids subsequently cool, there is the danger that, under the influence of the negative pressure building up in the inner container, the top wall of the inner container of synthetic material is lowered to such an extent that the closing cover of the filler connection integrally formed with the top wall of the inner container can no longer be opened with a commercially available wrench. The danger of lowering of the top wall of the inner container also exists when an agitating mechanism is placed on the filler connection. The present invention is based on the object of increasing the stability of the top wall of the inner container of synthetic material in order to avoid a drop of the top wall with the filler connection under the influence of external or internal forces. In accordance with the invention, this object is met by a transport and storage container having the features of claim 1. The subclaims contain advantageous and useful further developments of the invention. By fastening the top wall of the inner container of synthetic material . to the protective cover of the transport and storage container, a 'lowering or a drop of the top wall with the filler conrtection under the influence of external and internal forces is made impossible. The suspension of the top wall of the inner container at the protective cover of the transport and storage container makes it possible to reduce the wall thickness of the top wal*l and, thus, to reduce the transport weight of the container and to safe material costs. In the following, the invention will be described with the aid of drawing figures whir show the following: Fig. 1 a perspective illustration of a transport and storage container, Fig. 2 a partial top view, on a larger scale, of the assembled protective cover of the container with the fastening of the top wall of the inner container of synthetic material to the protective cover, and Fig, 3 a partial sectional view of the protective cover of the container taken along line III-III of Fig. 2. The transport and storage container 1 for liquids which can be used as a disposable container and a reusable container includes as principal structural components a replaceable parallelepiped inner container 2 of polyethylene with four side walls 2a-2d, a bottom wall 3 constructed as a draining bottom, an upper wall 4 with an inlet connection 5 and an outlet connection 7 with a drain cock 8, an outer casing 9 of intersecting vertical and horizontal grate rods 10, 11 of metal, a pallet-like underframe 12 with a bottom basin*^of sheet metal for receiving with frictional engagement the liner container 2 of synthetic material, and a cover 14 of sheet metal for protecting the inner container 2. The bottom basin 13 rests with a certain bottom clearance on corner and middle legs 15, 16 and a bottom frame 17 or skids, so that the gripping arms of a transport device, for example, a fork lift, can be moved from four sides under the bottom basin 13 for transporting the transport and storage container 1. The legs 15, 16 and the bottom frame 17 or the skids are of metal or an electrically conductive synthetic material, for example, polyethylene with a conductive soot portion. The pallet-like underframe 12 of the transport and storage container 1 has length and width dimensions conforming to European standards. A support insert 18 with four side walls 18a-18d is arranged between the inner container 4 of synthetic material and the outer casing 9 of the transport container 1. The single-piece support insert 18 is manufactured by stretching a pipe element of metal on a stretching press. Electric charges which may possibly occur when filling the transport and storage container with a liquid and when removing liquid from the container 1 due to liquid friction at the surfaces of the inner container 2 of synthetic material are discharged into the grayed through the support insert 18, the outer casing 9, the bottom basin 13, the corner and middle legs 15, 18 and the bottom frame 17. The top wall 4 of the inner container 2 has a middle portion 19 with the filler connection 5 and two raised outer portions 20, 21 which, when the container 2 is filled with a liquid by up to 95%, form hollow spaces 22, 23 in which gas evaporating from the liquid can collect in the case of increased outer temperatures. Two fastening eyes 26, 27 are integrally formed at the steps 24, 25 between the middle portion 19 and two outer raised portions 20, 2i of the top wall 4 of the inner container 2. tn the area of the indentation 28 of the entry opening 12 of the protective cover 11 of the transport container 1, corresponding slots 29, 30 for passing therethrough the fastening eyes 26, 27 when fastening the protective cover 11 are arranged at the upper ends of the vertical grate rods 9 of the outer casing 8. For fastening the top wall of the inner container 2 to the protective cover 11 of the transport container 1, pins or bolts 31 of synthetic material or metal are inserted through the fastening eyes 26, 27 which protrude upwardly above the cover. 1. Transport and storage container for liquids, with a pallet-like underframe, an inner container of synthetic material with four side walls, a bottom wall and a top wall, a closeable filler connection integrally formed at the top wall and an outlet connection with a discharge fitting integrally formed at the lower portion of a side wall, an outer casing composed of vertical and horizontal grate rods or constructed as a sheet metal casing, and a removable protective cover of metal or synthetic material 'fastened to the outer casing with a central entry opening to the filler connection of the inner container closeable by a screw cap, characterized by fastening eyes (26, 27) integrally formed at the top wall (4) of the inner container (2), slots (29, 30) arranged in the protective cover (11) for passing therethrough the fastening eyes ;(26, 27) when fastening the protective cover (11) to the outer casing (8) of the transport container (1), and securing elements for insertion through the fastening eyes (26, 27) of the inner container (2) which protrude upwardly above the protective cover (11) . 2. Container according to claim 1, characterized by bolts (31) of synthetic material or metal which can be inserted through the fastening eyes (26, 27) of the inner container (2) for fastening the top wall (4) of the inner container (2) to the protective cover (11). 3. Container according to claims 1 and 2, characterized in that the fastening eyes (26, 27) are integrally formed at the steps (24, 25) between the middle portion (19) and the outer raised portions (20, 21) of the top wall (4) of the inner container (2) of synthetic material. 4. Container according to one claims 1-3/ characterized by a support insert arranged between the inner container (2) and the outer casing (8) , wherein the support insert (18) has four side walls (18a - 18d) and is composed of an electrically conductive material, preferably metal. Transport and storage container for liquids, with a pal let-like underframe, substantially as herein described with to the accompanying drawings.
