Definitions

  • the invention relates to a flexible liquid tank with its overall volume bounding flexible outer walls, within which at least one planar connecting element is provided which is fastened at least with a first portion to at least a portion of one of the outer walls and thereby arranged angularly relative to the portion of the outer wall and with a second portion anchored at another location within the tank, thereby maintaining the portion of the outer wall substantially in position and also dividing the tank into at least two chambers.
  • Such a liquid tank is from the GB 578 855 A known, which forms the closest prior art, from which the present invention proceeds.
  • Flexible fluid tanks whose flexible outer walls or outer wall sections together form a one-piece or multi-piece shell, depending on the construction, are used for receiving, storing and transporting liquids, in particular liquid foodstuffs such as drinks of all kinds, preferably wines and fruit juices, and cooking oil as well as liquid chemicals of all kinds such as oils and paints used.
  • the flexible liquid tank is usually arranged in a container by the interior of the container with the flexible liquid tank is substantially lined.
  • the flexible liquid tank is first introduced in the empty state into the interior of the container and then filled with the desired liquid.
  • the container gives the flexible liquid tank the necessary support. With the help of a flexible liquid tank one is thus able to store and transport liquids in a container.
  • the flexible liquid tank takes on the task of a liquid-tight inner lining and is therefore also referred to as "inliner".
  • the flexible fluid tank is made of a supple, flexible material, which is usually a sheet material. This material must be liquid-tight to prevent leakage, and also be such that the quality of the liquid transported goods does not suffer, which is particularly important for liquid foods of great importance.
  • the containers lined and filled with a flexible liquid tank are usually transported on trucks, rail vehicles or ships.
  • transport in particular during braking or acceleration, when moving by means of a crane, for example from a lorry to a ship or vice versa, or in the case of accidents, for example, when the container falls from the crane harness, the liquid volume in the flexible liquid tank inside the container inevitably in motion, shifting its center of gravity in the direction of the forces acting on it. This creates a volume or mass turmoil.
  • One reason for the occurrence of such a surge is the fact that the flexible liquid tank is usually the interior of the container does not completely fill, but a void with a certain height to the ceiling of the container must remain free for weight reasons. This void is temporarily filled by the back-and-forth sloshing liquid.
  • the flexible liquid tank is of course limited by an upper portion of the shell, but this is flexible and yielding and therefore bulges due to the volume surge upwards.
  • a flexible liquid tank with its total volume bounding flexible outer walls, within which at least one planar connecting element is provided which at least fixed to at least a portion of at least a portion of the outer walls while angularly disposed relative to the portion of the outer wall and with anchored to a second portion at a different location within the tank and thereby substantially holding the portion of the outer wall in position and further dividing the tank into at least two chambers, characterized in that at least two adjoining or adjacent chambers each have their own Envelope are enclosed, the adjacent or adjacent portions of the shell are attached to a connecting element and the tank is surrounded on its outer walls by an additional shell.
  • the inventive arrangement of at least one connecting element can be a bulging of the outer walls of the flexible liquid tank substantially prevent or at least significantly reduced. Because with the help of at least one connecting element according to the invention, the Au ⁇ en endeavor are held substantially in position. In the event of higher hydrostatic base forces, and in particular high dynamic, volumetric mass forces caused by movement of the liquid volume in the flexible liquid tank, the outer walls of the flexible liquid tank will become more inward by means of the at least one connecting element - usually multiple connecting elements being provided pulled and thereby absorb at least a portion of these forces. This has the consequence that the outer walls of the flexible liquid tank even stand at least in some areas of the wall of the flexible liquid tank receiving container, resulting in a significant relief of the container walls.
  • the at least one connecting element assumes the function in the manner of a bulkhead or a transverse connection for receiving compressive forces, in particular in the case of strong fluid movements.
  • the at least one connecting element subdivides the flexible liquid tank into at least two chambers, which is the case in particular when the connecting element is designed as a wall element or wall and terminates substantially completely over its entire edge with the inside of the outer walls.
  • the cavity of the flexible liquid tank is divided into at least two, usually a plurality of smaller chambers, which results in each case a significantly smaller volume of volume for each individual chamber compared to a large, continuous cavity. Due to the smaller capacity in each chamber significantly lower fluid movements take place, resulting in correspondingly lower force.
  • a multi-chamber arrangement forms a kind of stabilization system, which is able to absorb the high dynamic forces of the fluid largely within the flexible liquid tank.
  • this is achieved in that at least two mutually adjacent or adjacent chambers are each surrounded by a separate shell and the adjacent or adjacent portions of the shell are individually or jointly at least partially attached to a connecting element and the one or more connecting elements the respective Accordingly, limit the chamber accordingly and at least partially absorb the forces in the manner described above.
  • the formation of such a multi-chamber system for achieving a stabilizing structure in the aforementioned sense is an independent invention aspect
  • Such chambers can be designed and arranged differently.
  • the flexible liquid tank is also surrounded on its outer walls by a shell, which may contain, for example, fabric material and in particular provides both a reinforcement and additional protection.
  • At least one chamber communicates with at least one further chamber.
  • the two chambers separating the connecting element has at least one passage.
  • This passage may have a, preferably closable and / or semipermeable, valve.

  • the chambers may be one above the other, next to each other and / or behind each other. Alternatively or additionally, zigzag or star-shaped arrangements and configurations are also conceivable.
  • At least a portion of the shell is provided as part of the outer walls, which applies to the outer chambers, wherein in such a construction, the outer walls is then formed essentially of the outer portions of the sheaths of the individual chambers or consists of these.
  • the at least one connecting element may be arranged with its first section approximately at right angles to the section of one of the outer walls, to which the connecting element is fastened with its first section, in order to make the previously described tensile forces act on the corresponding outer wall.
  • the connecting element For particularly effective is a substantially rectangular attachment of the connecting element.
  • the connecting element or the connecting elements In order to withstand the forces described above and at the same time to exert the necessary, inwardly directed tensile forces on the outer walls of the flexible liquid tank, the connecting element or the connecting elements must of course be sufficiently dimensioned and must also, of course, a correspondingly strong attachment of the connecting element or the connecting elements be realized on the associated Au- ⁇ enwand the flexible liquid tank.
  • the at least one connecting element should consist essentially of flexible, but low-stretch material.
  • At least one connecting element should connect these two outer wall sections together and secured thereto.
  • the flexible liquid tank has two long sides and two narrow sides, whereby the flexible liquid tank usually has a cuboid shape. Since the outer walls on the long sides, so the longitudinal walls, are more prone to buckling than the walls on the narrow sides and otherwise in most cases, the movements of the surge takes place in the longitudinal direction, which usually forms the transport direction of the flexible liquid tank receiving container should at least one connecting element with its first portion to be attached to at least one located on one of the long sides portion of the outer walls.
  • the at least one connecting element extends at least in sections approximately in the direction of the long side.
  • at least one connecting element forms a kind of intermediate wall or intermediate floor and connects the two opposite outer walls on the long sides, whereby the connecting element lies approximately in a horizontal plane and divides the cavity of the flexible liquid tank in the vertical direction into an upper portion and a lower portion.
  • the flexible liquid tank is correspondingly divided into a plurality of superimposed sections.
  • these sections can extend over the entire long side and at the same time over the entire narrow side, whereby individual chambers arise.
  • the at least one connecting element extends at least in sections approximately transversely to the direction of the long side.
  • the flexible liquid tank is divided in the longitudinal or horizontal direction into at least two sections lying one behind the other.
  • the flexible liquid tank is correspondingly divided into a plurality of successive sections.

  • the at least one connecting element can also extend diagonally within the flexible liquid tank.
  • a spider-shaped arrangement of a plurality of connecting elements in particular with a common node located approximately in the middle within the flexible liquid tank.
  • the at least one connecting element can be designed and arranged as a transverse strut.

  • the tank can be produced with a cuboid shape, which is particularly advantageous for transport in a container, which also has a cuboid shape.
  • FIG. 1 are a flexible liquid tank 2 in a first embodiment and a container 4, in which the flexible liquid tank 2 is arranged, shown.
  • the flexible liquid tank 2 has in the illustrated embodiment, the shape of a cuboid with two spaced apart long sides 2a, two end faces forming narrow sides 2b, a bottom 2c and the ceiling forming the upper part 2d.
  • the container 4 it is expedient in the illustrated embodiment to form the flexible liquid tank 2 in a cuboid shape. Because the containers with the usual standard dimensions have a cuboid shape. Only in this way is it possible to arrange the flexible liquid tank 2 with the greatest possible utilization of the available space in the container 4 by inserting the flexible liquid tank 2 into the container 4 as a liquid-tight inner lining.
  • the container 4 has two spaced apart long sides 4a, two respectively forming the end sides narrow sides 4b, a bottom 4c and a cover forming the top 4d.

  • the container 4 is transported with the therein contained flexible liquid tank 2 usually in the longitudinal direction according to arrow X- Especially at changes in speed, the liquid volume in the flexible liquid tank 2 within the container 4 but inevitably gets into motion and shifted his focus in the direction of the forces acting. This creates compressive forces which act on the long sides 2a and the narrow sides 2b of the flexible liquid tank 2 and are correspondingly transmitted to the long sides 4a and narrow sides 4b of the container 4. Those pressure forces are in FIG. 1 indicated schematically by "F" arrows. Due to these pressure forces according to the arrows F, there is a risk that the flexible liquid tank 2 and thus also the container 4 bulges, this danger being greatest on the long sides 2a and 4a, respectively.

  • This can even lead to the outer walls of the flexible liquid tank 2, at least on its long sides 2a from the adjacent walls of the container 4 inwardly stand out, which has a significant relief of the walls of the container 4 result.
  • the entire flexible liquid tank 2 is additionally surrounded by a protective cover 10, which preferably contains a tissue for reinforcement.
  • FIG. 2 shows in cross section a section of the flexible liquid tank 2 of FIG. 1 in the area of one of the long sides 2a. Also FIG. 2 indicates that the individual chambers 8 are formed by the spaced arrangement of the connecting elements 6.

  • FIGS. 1 and 3 show over the entire width corresponding to the width of the narrow side 2b continuous arrangement of the chambers, which thus thus extend from the outer wall on one long side 2a to the outer wall on the other long side 2a and thus limited only by these two outer walls, it is an obvious course also conceivable to arrange at least two chambers 8 side by side between the two opposite long sides 2a. Such an arrangement is exemplary in FIG. 4 shown.
  • the chambers 8 communicate with each other.

  • the flexible liquid tank 2 Before the flexible liquid tank 2 is filled, it must be introduced into the container 4. The arrangement of the flexible liquid tank 8 in the container 4 thus takes place in the empty state.

  • the flexible liquid tank 2 is made of a conformable, flexible material, which is usually a sheet material. This material must be liquid-tight to prevent leakage, and also be such that the quality of the liquid transported goods does not suffer, which is particularly important for liquid foods of great importance. Usually, the flexible liquid tank 2 is removed after a single use and emptying from the container 4 and then disposed of ⁇ end, thereby eliminating a complex cleaning of the container.
