Definitions
- the present invention relates to a liquid container of the Intermediate Bulk Container (IBC) type.
- IBC Intermediate Bulk Container
- IBCs Intermediate Bulk Containers
- the tank is usually made of a plastic material, has an opening in its upper portion for receiving a liquid, and an opening in its lower portion for discharging the liquid via a discharge device, such as a tap.
- the cage surrounds the tank along at least four sides to prevent lateral displacements when the container is moved and is typically composed of vertical and horizontal bars.
- the pallet is a support element located below the cage and the tank and may be made, for example, of wood, plastic or metal.
- the most common type of pallet comprises parallel runners, generally three runners, with cross members mounted thereto and supporting in turn support boards.
- the pallet has two openings at each side, for receiving the forks of a lift truck. As the pallet and the lift truck are mutually coupled the container may be moved.
- IBC liquid containers are used in logistics for efficiently and inexpensively carrying large amounts of liquids. When these containers reach their destination and before being transported, they are stored in appropriate warehouses. For more efficient use of the height of warehouses, the containers are vertically stacked, each container being placed on two parallel rails.
- the containers are often disposed on the rails in side-by-side relationship, such that the rails are parallel to the short sides of the pallet, whereas the runners, parallel to the long sides of the pallet, extend from one rail to the other.
- US5058747 discloses an IBC according to the preamble of appended claim 1 which consists in a plastic container surrounded by a metal cage, the whole being supported on a wooden pallet.
- the weight of the tank acts on the long sides of the pallet which, as mentioned above, rest upon the rails at the ends of the long sides. Under the weight of the tank, the wooden pallets are likely to bend at their central portion, between the distant support points.
- the aforementioned warehouses may be also equipped with robotized handling systems, whose operation may require pallet bending to fall within given limits to ensure the function of such automatic systems.
- the object of the present invention is to provide a liquid container having a bending-resistant pallet, in which the weight of the tank is effectively discharged at the ends of the runner whereat the container may lean on the rails.
- a further object is to maintain a low cost of the pallet, and hence of the whole container, by an efficient use of the construction materials.
- liquid container as shown in the accompanying figures shall be deemed to be schematically illustrated, not necessarily drawn to scale, and not necessarily representing the actual proportions of its parts.
- Figures 1 and 2 show a liquid container of the present invention, referenced 1.
- the container In use, the container is designed to be moved, for instance, by a lift truck, and to rest upon two parallel tracks for easy storage thereof in appropriate warehouses.
- the container comprises a pallet 2, a metal cage 3 and a tank 4.
- Various types of bulk liquids may be stored in the tank 4, such as edible liquids, industrial liquids or flammable liquids.
- the capacity of the tank 4 ranges from 500 to 1500 liters, and the most common types of tanks 4 have a capacity of 600 liters, 1040 liters or 1250 liters.
- the tank is made of a plastic material, preferably high-density polyethylene. This material prevents contamination of the liquid and provides adequate chemical and structural resistance.
- the tank 4 comprises an upper loading opening 41 and a lower discharge device 42.
- the loading opening 41 is located in a top wall of the tank and may have various shapes, e.g. a circular shape.
- the loading opening 41 is suitably sized to receive a liquid, directly or via appropriate equipment.
- the loading opening 41 may be engaged by a cap to avoid accidental leakage of liquid.
- the discharge device 42 is located in a lateral wall of the tank, in a lower portion thereof.
- the discharge device 42 consists of a fluid flow regulating device, such as a tap, and is connected to a discharge opening in the tank.
- the discharge device 42 may be open to allow the liquid to flow out of the liquid container, or closed to block it.
- the tank 4 is accommodated within the cage 3.
- the cage 3 comprises a plurality of walls 31 composed of metal bars.
- the cage 3 comprises four side walls 31 to limit lateral movements of the tank 4, for example during handling of the liquid container 1.
- the cage 3 may comprise a top wall and/or a bottom wall. In any case, the cage 3 must be compatible with the possibility of loading and discharging the liquid from the tank 4 through the loading opening 41 and the discharge device 42.
- each wall 31 of the cage 3 comprises metal bars 32, which are parallel in a first direction, and metal bars 33, which are parallel in a second direction, perpendicular to the first direction.
- the liquid container 1 preferably comprises plastic protective elements 5 accommodated within the cage 3 proximate to its lower vertices 34.
- the protective elements 5 protect the cage 3, preferably at its weakest points, i.e. the vertices, from impacts of the tank 4.

Description
- The present invention relates to a liquid container of the Intermediate Bulk Container (IBC) type.
- The manufacture of containers for transport and storage of liquids having a capacity of about 1000 liters and known as IBCs (Intermediate Bulk Containers) is known in the art. These containers have a tank within a cage, and both are supported by a pallet.
- The tank is usually made of a plastic material, has an opening in its upper portion for receiving a liquid, and an opening in its lower portion for discharging the liquid via a discharge device, such as a tap.
- The cage surrounds the tank along at least four sides to prevent lateral displacements when the container is moved and is typically composed of vertical and horizontal bars.
- The pallet is a support element located below the cage and the tank and may be made, for example, of wood, plastic or metal. The most common type of pallet comprises parallel runners, generally three runners, with cross members mounted thereto and supporting in turn support boards. The pallet has two openings at each side, for receiving the forks of a lift truck. As the pallet and the lift truck are mutually coupled the container may be moved.
- IBC liquid containers are used in logistics for efficiently and inexpensively carrying large amounts of liquids. When these containers reach their destination and before being transported, they are stored in appropriate warehouses. For more efficient use of the height of warehouses, the containers are vertically stacked, each container being placed on two parallel rails.
- The containers are often disposed on the rails in side-by-side relationship, such that the rails are parallel to the short sides of the pallet, whereas the runners, parallel to the long sides of the pallet, extend from one rail to the other.
-
US5058747 discloses an IBC according to the preamble of appendedclaim 1 which consists in a plastic container surrounded by a metal cage, the whole being supported on a wooden pallet. - When IBC containers are placed on the rails, the weight of the tank acts on the long sides of the pallet which, as mentioned above, rest upon the rails at the ends of the long sides. Under the weight of the tank, the wooden pallets are likely to bend at their central portion, between the distant support points.
- The aforementioned warehouses may be also equipped with robotized handling systems, whose operation may require pallet bending to fall within given limits to ensure the function of such automatic systems.
- The object of the present invention is to provide a liquid container having a bending-resistant pallet, in which the weight of the tank is effectively discharged at the ends of the runner whereat the container may lean on the rails.
- A further object is to maintain a low cost of the pallet, and hence of the whole container, by an efficient use of the construction materials.
- These objects are fulfilled by a liquid container as defined in
claim 1. - The characteristics and advantages of the present disclosure will appear from the following detailed description of a possible practical embodiment, illustrated as a nonlimiting example in the set of drawings, in which:
-
