Definitions

  • the invention relates to a presentation insert for a flexible bulk material container according to the preamble of claim 1. Furthermore, the invention relates to a flexible bulk material container according to the preamble of claim 13.
  • Flexible bulk material containers are used for storage and transport of filled material. These are usually solid, preferably granular material, so materials of different grain size. Such flexible bulk containers, for example, simply referred to as “large bags” or as a “flexible middle container for bulk goods" according to the English “Flexible Intermediate Bulk Container” or also referred to as FIBC.
  • a flexible bulk material container of the type mentioned here approximately comprises a volume of approximately 1,000 liters, generally approximately between 500 liters and 2,000 liters.
  • the addressed here flexible bulk containers are usually made of a stable plastic fabric, in particular polypropylene (PP), or a material with comparable properties.
  • PP polypropylene
  • Such fabric-like materials have high durability and tear resistance.
  • the containers are in unfilled state can be folded to save space.
  • loops are typically arranged on the bulk goods container, for example in the region of the corners or on the side surfaces. These can be taken for example by a crane or the like.
  • the flexible bulk material containers In order to be able to absorb particularly fine or sensitive materials, the flexible bulk material containers often have an inner lining, a so-called insert or "inliner". This is essentially formed according to the shape of the flexible bulk goods container and used in this. Such is typically formed from a film and is accordingly also referred to as a film insert. It has at least one bottom and a peripheral wall, which is formed in accordance with the inner shape of the bulk goods container usually with cuboid basic shape. Optionally, in addition to a floor in addition a lid may be provided as the top. To fill the material is then often arranged in the top of a filling or a filler neck, which is or in particular closable.
  • a so-called insert or "inliner” is essentially formed according to the shape of the flexible bulk goods container and used in this. Such is typically formed from a film and is accordingly also referred to as a film insert. It has at least one bottom and a peripheral wall, which is formed in accordance with the inner shape of the

  • each of the stiffening elements is connected to two adjacent or two other, for example, opposite wall portions of the wall.
  • the stiffening elements can for example stabilize two adjacent wall sections over the corner or just opposite wall sections. In the latter case, as a rule, a problematic crossing region of the stiffening elements is still present.
  • stiffening elements for example, foil sections or flexible gratings, for example made of plastic, are used. In order to connect these with the wall, seams or even spot welds are usually made.
  • the object of the present invention is therefore to provide a film insert for a flexible bulk material container, in which stiffening elements permanently stable and in particular without risk of damaging the outer wall can be attached.
  • a foil insert with the features of claim 1 solves this problem. Accordingly, the at least one stiffening element is connected to the wall sections by means of an intermediate piece. Thus, a connection with the intermediate piece and the stiffening element on the one hand and between the intermediate piece and the wall on the other hand can be produced. Thus, various bonding methods can be used and different material properties can be taken into account.
  • the intermediate piece is formed in particular from the same material as the wall. This offers the advantage that a cohesive connection between the intermediate piece and the wall can be produced. Weak points due to different materials are avoided.
