Definitions

• the invention relates to a pallet container with a lower pallet, with an inner plastic container arranged thereon with an upper filling opening and bottom removal valve and with an outer reinforcement jacket which is tightly fitting against the plastic container and encloses it and is attached to the pallet.
• Pallet containers of this type are generally known. These pallet containers are usually cuboid with a sturdy frame construction of the outer reinforcing jacket (e.g. DE-GM 89 06 059), but also round or cylindrical or oval-round pallet containers are known (e.g. DE-GM 86 27 708).
• a disadvantage of purely rectangular pallet containers is that, owing to the high hydrostatic internal pressure in a filled pallet container with a capacity of usually approx. 1,000 liters, and additionally during transport by sloshing the liquid container contents in particular in the lower area of the container Comparatively large compressive forces occur with the entire large flat container walls or the reinforcing jacket with the aim of bulging or bulging outwards, which is why a stable, rigid and heavy-weight outer frame construction is required.
• cylindrical or round or oval pallet containers When viewed in cross-section, cylindrical or round or oval pallet containers have an optimal absorption of radial compressive stresses and tangential tensile stresses, but they have the disadvantage in comparison a lower filling volume or poor use of space in the corner areas of a large pallet.
• the pallet container should overall be inexpensive to manufacture and, particularly after its use, be recyclable in an environmentally friendly manner, i.e. be easy to take apart.
• This object is achieved in that the upper circumferential area of the plastic container is positively and / or non-positively connected to the reinforcing jacket and prevents the plastic container from evading or yielding radially outwards or inwards.
• the plastic container cannot deform or distance itself independently of the support jacket, bulging of the straight side walls and retraction of its corner wall areas is made possible by the positive or non-positive connection of the circumferential upper circumferential area prevented or significantly reduced.
• the inner container can be made thin-walled, stiffeners such as reinforcing ribs or circumferential stiffening flanges for the inner container itself can be dispensed with; this saves plastic material.
• the holding element on the upper circumferential area of the plastic container consists of a circumferential flange edge with an angular or U-shaped flange edge shape in cross-sectional view with an outer flange limitation which defines the upper edge of the reinforcing jacket, for example an approximately 5 : mm thick cardboard, covered in the axial direction and in the radial direction from above and in particular from the outside, for example over an (axial) length of, for example, 15 mm, overlapping and protecting.
• the flange edge running around the top of the blow-molded plastic container is connected to the plastic container via an elastic, obliquely running, comparatively thin connecting web.
• the flange edge is already produced during the blow molding process, ie, it is upset and shaped in the blow mold by means of a mold slide.
• the flange edge could also be designed as a separate injection molded part and glued or welded onto the plastic container.
• the circumferential U-shaped flange limitation supports and protects the upper edge of the cardboard jacket in the event of axial stacking loads, in particular in the case of partial pressure loads by force distribution or pressure force compensation against buckling or compliance (denting / bulging) in the radial direction.
• the upper edge of the container and the upper edge of the reinforcing jacket are thus securely connected to one another over the entire circumference.
• the lower edge of the reinforcing material is fixed all around, that a circumferential corresponding groove (width, for example, 6 mm, depth, for example, 8 mm) is milled or cut into the surface of the pallet in a simple manner, into which the lower edge of the reinforcing jacket is inserted in a form-fitting manner and thereby, in particular in the radial direction, inwards and outwards is fixed.
• a circumferential corresponding groove width, for example, 6 mm, depth, for example, 8 mm
• the pallet container Due to the upper and lower circumferential fixation of the reinforcement jacket, e.g. a cardboard jacket wound and glued from kraft paper, the pallet container has a higher overall rigidity or dimensional stability even when the loads are unevenly or at an angle.
• the cardboard jacket is particularly inexpensive to manufacture, very light in weight and can be fed together with the pallet for final recycling (e.g. burning the wooden pallet).
• the inner container made of plastic can e.g. crushed and again fed to a molding process (recycling). From today's environmental policy point of view, this is of considerable importance.

• the sector 16 with a straight wall 18 is approximately 20 and the sector 20 with a circular wall 22 is approximately 70. Due to this special configuration, the pallet container is given an increased usable volume compared to a round container for a given size of the pallet, and in comparison to rectangular pallet containers it is possible to dispense with oversized, expensive frame constructions for stabilizing the reinforcing jacket due to better inherent stability .
• the large, flat wall of the plastic container - in particular in the lower container area - has the hydrostatic internal pressure of the filling material the great effort to cry outwards. This means that the wall of the plastic container is drawn inwards in the corner areas, since the circumferential length of the plastic container cannot increase.
• the plastic container is therefore endeavoring to take the most exciting circular shape.
• the positive or non-positive fixed connection according to the invention between the inner container and the outer supporting jacket is provided.

• the effect that the plastic container in the filled state tends to bulge outwards in the areas with a straight, flat wall and to radially recede in the areas with a circular wall to move in, eliminated by the all-round positive connection of the inner thin plastic container with the outer reinforcing jacket.
• the inventive design of the pallet container makes it possible to make the plastic container thinner with a material saving of approximately 10% (a conventional 1,000 liter plastic container weighs approximately 22 kg).
• the viewing window or openings 32 'for checking the fill level in the corner area are arranged with a circular wall in the cardboard jacket 30.
