Description
- Containers which enable products to be transported safely are generally used for the targeted transport of products, in particular liquids or free-flowing materials, including hazardous substances or food. The containers have a large volume of 300 l or more, for example 1000 l, and are in particular known under the name IBC, i.e. intermediate bulk container. The known containers for liquids or free-flowing materials have a wall, a filling opening and an outlet opening. The wall of the container is made of metal, so that the container has a high long-term stability and is very easy to clean. Metal containers are particularly well suited for the transport of hazardous substances, since they have high bursting strength.
- In order to be able to guarantee bursting strength and stability up to now, the known metal containers generally have a wall thickness of 1.5 mm or more. A container with a wall made of metal is desirable, and can be produced in a way that conserves resources.

Such a structure enables the advantages of durability and easy cleanability of a metal container to be retained, but on the one hand allows the forming of the wall of the metal container with a smaller wall thickness in order to reduce the consumption of higher quality material, and on the other hand continues to provide the desired stability and bursting strength to be able to ensure that the metal inner container is surrounded by a lattice structure, which can be made of lower quality material and which can maintain stability or bursting strength.

- The wall of the inner container is preferably made of stainless steel, in particular of an austenitic steel or an austenitic alloy. Such materials lead to a particularly good cleanability of the inner container.
- A particularly preferred development of the invention provides that the wall of the inner container has at least one bead in which a rod of the lattice structure can be arranged. This can improve the stability of the container, since the inner container can expand into the lattice structure.
- The inner container is preferably designed with a bottom side, a cover side and in particular four side walls, the filling opening in particular being arranged in the cover side and the outlet opening in the bottom side. An approximately cuboidal configuration of the inner container can preferably result, which is particularly suitable for transport, since it can fill an existing volume better than, for example, barrel-like configurations.
- According to an advantageous development of the invention, an outlet recess, in which the outlet opening is arranged, is arranged in the bottom side. This can allow the inner container to be emptied as completely as possible.
- The outlet opening preferably comprises an outlet tap, in particular with a pivoting lever. This allows easy handling.
- According to a preferred embodiment of the invention, the outlet tap is set back in the wall of the inner container.

A bottom element, which can comprise flat sections, offers a particularly stable support for the inner container. If the bottom element is designed as a pallet, in particular as a transport pallet, for example as a standardized transport pallet such as the Europool pallet, it can be easily transported and moved, for example, with industrial trucks or forklifts.
- According to an advantageous embodiment of the invention, the bottom element has a recess in which the outlet recess of the inner container is arranged in particular in a form-fitting manner Such a recess can simplify the alignment of the inner container in the lattice structure and prevent the inner container from slipping in the lattice structure.
- At least two, for example three to five, longitudinal rods are preferably arranged on the bottom element on each side, and are arranged with a first end on the bottom element, in particular screwed to it. A stable lattice structure can be achieved in this way. Screw connections enable the most distortion-free fixation possible and can enable a sufficiently stable fixation to enable desired bursting strengths.
- The longitudinal rods are advantageously fixed relative to one another at a second end by a circumferential first transverse rod, wherein the first transverse rod is in particular screwed to the longitudinal rods. Such a first transverse rod can enable a frame-like construction.
- According to a preferred development of the invention, parallel to the bottom element at least one, preferably two or more, tension rod(s) connect(s) two opposite sections of the first transverse rod to one another. Such a tension rod or such tension rods can secure the inner container against falling out of the lattice structure and also increase the bursting strength. The tension rod is also preferably screwed to the transverse rod.
- The longitudinal rods are preferably fixed relative to one another by at least one, preferably a plurality of circumferential transverse rods, the transverse rods being in particular screwed to the longitudinal rods. Such transverse rods can further increase the stability of the lattice structure.

In order to enable theinner container 20 to be emptied as completely as possible, anoutlet recess 25, in which theoutlet opening 23 is arranged, is preferably arranged in thebottom side 20 a. Theoutlet recess 25 can be designed, for example, as a channel which widens conically toward theoutlet opening 23 and is formed by twoupstands outlet recess 25 can extend over a large part of the depth t of theinner container 20, for example over 50% of the depth t or more. Theoutlet tap 26 can be set back in thewall 21 of the inner container 20 (see in particularFIG. 1 ), so that it does not protrude and is arranged to be protected against damage. - The
lattice structure 30 comprises a plurality ofrods bottom element 31. Thebottom element 31 can be designed as a pallet, in particular as a transport pallet, for example as a standardized transport pallet such as the Europool pallet. Thebottom element 31 can have a bearing surface for theinner container 20, which comprises at least several partial bearing surfaces or is even designed as a continuous bearing surface in order to be able to reliably support the weight of a filledinner container 20. The bottom element can have arecess 31 a, in which theoutlet recess 25 of theinner container 20 can be arranged in particular in a form-fitting manner - The
lattice structure 30 can be formed adjacent to the outer surface of theinner container 20. In particular, thelattice structure 30, like theinner container 20, is cuboid. - At least two, for example three to five, in the embodiment example shown four,
longitudinal rods 32 can be arranged on thebottom element 31 on each side, which in particular has a rectangular base area. Thelongitudinal rods 32 have afirst end 32 a and asecond end 32 b and are arranged with theirfirst end 32 a on thebottom element 31, for example by means of a screw connection. The screw connections are in particular arranged in such a way that they are not arranged to protrude outwards. Thelongitudinal rods 32 are fixed relative to one another at theirsecond end 32b by a circumferential firsttransverse rod 34, the firsttransverse rod 34 being in particular screwed to thelongitudinal rods 32. The firsttransverse rod 34 encloses anupper side 30 aof thelattice structure 30. - Through this upper side 30 a, the
inner container 20 can be inserted into thelattice structure 30 during the manufacture of thecontainer 10. Subsequently, at least one, in the present case twotension rods 36, which connect twoopposite sections transverse rod 34 to one another, can be arranged on thetransverse rod 34. The connection is preferably realized by a screw connection. Thetension rods 36 can in particular be arranged to extend over the recessedsection 20 b-1 of thecover side 20 b. When theinner container 20 expands, this enables the steps of the recessedsection 20 b-1 to be supported on thetension rods 36. - In addition to the first
transverse rod 34, thelattice structure 30 can have one or more, in the present case three, furthertransverse rods 35, which fix thelongitudinal rods 32 around the circumference between thefirst end 32 a and thesecond end 32 b and are connected to them in particular by screw connections. - The production of the
lattice structure 30 by means of screw connections enables production without deformation. In addition, theinner container 20 can be replaced in a simple manner if necessary. The screw connections can have mechanical safeguards against unscrewing. Alternatively, an adhesive securing is conceivable. - The
bottom element 31 can be made of metal, wood or plastic. Therods rods - One, preferably a plurality of
beads 24 can be arranged in thewall 21 of theinner container 20, in particular in theside walls 20 c of theinner container 20. Thebeads 24 are preferably arranged in such a way that when theinner container 20 expands, one of thelongitudinal rods 32 can come to rest at least in sections in one of thebeads 24. Thebeads 24 can be arranged to extend over the entire height h of theinner container 20. Thebeads 24 can also provide space for the screw connections. -
