Two edges have tabs folded downwards and the two other edges are similarly folded upwards. On the circumference of the pallet, saw-tooth tabs may be formed and are folded over by 90 deg. upwards and downwards.

Description

The invention relates to a plate made of thermoplastic material, which enables packaging or transport containers to be combined in layers to form a self-supporting transport unit.

It is known to combine packaging or transport containers in layers into transport units in such a way that thermoformed plastic plates or plastic parts produced by injection molding are inserted between the individual containers or packaging. It is also known to use intermediate layers made of corrugated cardboard, solid cardboard and stacking plates or intermediate plates made of metal. Finally, wood panels and fiberboard or stacked panels made from combinations of the materials and systems mentioned have also become known.

The previous solutions, however, have the disadvantage that they are generally produced in complex manufacturing processes and therefore require a high level of energy during production. Furthermore, due to the technical conditions in their manufacture, they have an unfavorable relationship between the gross dimensions of the stacking plates and the usable area. Furthermore, many of the solutions mentioned above have the disadvantage that they can be used several times fail early due to damage. Another disadvantage of the systems mentioned above is that the material usability after use is not ensured or cannot be demonstrated. Finally, a further disadvantage of the systems mentioned above is that they generally only secure the lower or the load unit standing on the lower plate, but not both load units at the same time.

The present invention has for its object to avoid the disadvantages inherent in the systems mentioned above and to create a stacking plate which is simple to manufacture and versatile in its application.

To solve the problem, a plate made of thermoplastic material for combining packaging or transport containers into a self-supporting transport unit is proposed, which is characterized in that the plate has tabs bent by 90 ° on its peripheral edges.

A further possible embodiment of the plate according to the invention consists in that, on the peripheral edges, sections are alternately provided with tabs bent upwards by 90 ° and tabs bent downwards by 90 °.

Another possible embodiment is that in the case of a rectangular plate, two peripheral edges have tabs bent downwards by 90 °, while two other peripheral edges have tabs angled upwards by 90 °.

Significant advantages are achieved with the stacking plate according to the invention. The thermal folding of the tabs remaining on the circumference of the plastic plate alternately creates a plate offset by 180 ° upwards and downwards, which encloses a surface between the tabs both on the top and on the underside that corresponds to the surface of the pallet or corresponds to the base area of the packaging unit. It is possible to preferably measure the plate 800 mm x 1000 mm or 1000 mm x 1200 mm. In this way it is possible to place the plate on the corresponding transport pallets used in industry, in such a way that this plate can no longer slide over the pallet underneath.

Other dimensions are also conceivable, so that pallet units lying outside the norm, e.g. B. display pallets can be formed in this form. The plate placed on the pallet enables the user to place a pallet layer with packaging or transport containers on the pallet in a non-slip manner due to the upward bends. The further layer structure of the pallet is carried out equally. At the end of the pallet unit, a plate according to the invention is also placed over the last layer, and it is possible to secure the load or pallet by simply tying it up with plastic or metal tape, owing to the cutout on the upper edge.

Thus, only one type of stacking plate according to the invention is required to form a self-supporting pallet or loading unit that is protected against slipping. This plate is the base plate, intermediate plate and end plate at the same time. Because of these possibilities, there are enormous advantages in the handling of empties and in the management of packaging materials and load carriers. It is often the case that the base plate, intermediate plate and cover plate of such a charge unit are of different construction or design. Because of the advantage of the plate according to the invention, it is possible to manage with only one system. This has enormous advantages in connection with the investment costs.

Due to the special construction of an embodiment, namely the sawtooth construction, it is possible to stack the stacking plate in the empty state without problems, space-saving and safe from slipping. The area of use extends to all transport containers that are suitable to serve as pallet layers, such as. B. folding boxes made of cardboard or corrugated cardboard, transport containers made of metal and plastic or wood and all others in the Materials used in the packaging industry. The type of packaging is particularly suitable when the packaging modules used are themselves not capable, due to their construction, of being stackable in the full state without an additional intermediate layer or of preventing the individual layers from slipping against one another.

Another embodiment of the invention relates to improving the stacking plate with regard to additional stability. Such a stacking plate is characterized by a profile made of plastic with a flat back part with two legs bent inwards and running parallel to the back part and a longitudinal slot formed by the edges of the legs, which profile is inserted over the tabs of the stacking plate.

According to a special embodiment, the back part of the profile can be glued or welded to the tabs at least at one point.

Finally, the plate of additional stability can be made by the following solution. Accordingly, the stacking plate is characterized in that the four protruding edge regions adjoining the plate surface are bent 90 ° upwards or inwards to form the peripheral edge and 180 ° downwards at the height of the peripheral edge.

As a result of the measure according to the invention, a stacking plate made of thermoplastic material is produced in one piece, in which the edge regions are bent over in a simple manner to produce a peripheral edge.

According to a special embodiment, the stacking plate according to the invention is characterized in that the four edge regions are divided into three parts to form the peripheral edge, the first part being turned upwards or inwards by 90 °, the second part at the height of the peripheral edge by 180 ° down and the third part by 180 ° is bent above and inside. This results in a further stiffening of the entire stacking plate.

The bent parts can be welded or glued to one another at least at one point.

A further embodiment of the stacking plate according to the invention consists in that a circumferential strip extending from the plate surface upwards and downwards is applied to the circumferential edge bent vertically upwards by welding or gluing.

For further reinforcement, the peripheral edge can be bent through 180 ° in the lower area and the bent part can be glued or welded to the remaining part.

Finally, in a further embodiment of the stacking plate according to the invention, the circumferential strip can consist of a full profile, in which a recess is provided for inserting the peripheral edge of the plate, the peripheral edge being glued or welded to the full profile.

The plate according to the invention will be explained in more detail with the aid of preferred embodiments with the aid of the drawings.

As can be seen from the figures of the drawing, an embodiment of the plate according to the invention consists of a rectangular plate body 1 made of thermoplastic material, in which tabs 2, 3 are provided on the front edges which are bent upwards by 90 °, while on the side edges by 90 ° downward bent tabs 4, 5 are arranged.

This plate according to the invention can be placed on a pallet such that the tabs 2, 3 and 4, 5 encompass the pallet base plate. If one package or several packages are applied to the top, the flaps 2, 3 bent upwards protect these packages from slipping. After a further plate according to the invention has been applied to the upper surface or surface of the package (s), further packages can then be arranged thereon, which are then also secured against slipping.

Fig. 2 shows a perspective embodiment of the plate according to the invention, in which all tabs are bent 90 ° upwards.

Fig. 3 shows a punched blank with which a plate can be produced according to the invention. Accordingly, this molding consists of a thermoplastic plastic plate 6 with sawtooth-shaped tabs 7.

These tabs are now alternately folded by 90 ° upwards and by 90 ° downwards and thus result in the finished plate shown in perspective in FIG. 4. As already described in FIG. 1, this plate is placed on one or more packaging layers. In this way, it secures this packaging / s against slipping on the pallet.

As can be seen from FIGS. 5 and 6, the plate according to the invention consists of a rectangular plastic plate 6 with sawtooth-shaped tabs 7. A plastic profile shown in FIG. 6 is pushed over the tabs 7 and has a flat back part 9 with two inwards bent legs 8 and extending parallel to the back part, the edges of which form a longitudinal slot 8 '. In this way, the spaces between the tabs 7 of the stacking plate are closed all around, both from above and from below.

This has the advantage that the product stacked on it is protected against slipping out or shifting at any point on the stacking plate. The legs 8 of the plastic profile are welded or glued to the flat back part 9 in one or more places in the spaces 11 between the tabs 7. This also increases the rigidity of the stacking plate and ensures that the profile does not slip. The corners 10 resulting from the mounting of the profile on the stacking plate can also be welded or glued, which brings about an additional stability of the plate.

As can be seen from FIG. 7, an embodiment of the stacking plate according to the invention consists of a plate body or a plate surface 1 with a circumferential peripheral edge 20. The peripheral edge 20 arises from the fact that the four projecting edge regions adjoining the plate surface 1 initially move 90 ° be bent at the top or inside. The edge regions are then bent downwards at 180 ° in the height of the peripheral edge, such that outer legs 15 are formed. The inner legs 16 and the outer legs 15 of the peripheral edge 20 can be glued or welded to one another at at least one point.

In the embodiment of the stacking plate according to FIG. 8, the four edge regions for forming the peripheral edge 20 are first bent in such a way that the first part is bent upwards, the second Part is bent downwards by 180 ° and the third part in turn is bent upwards or inwards by 180o. In addition to the legs 15 and 16, this results in further legs 21 running inwards. Here, too, both the legs 16 and the legs 21 can be glued or welded to the outer legs 15.

With the embodiment shown in FIG. 8, as shown in FIG. 8, the peripheral edge is bent once by 90 ° upwards or inwards and then by 180 ° downwards. This results in outer legs 15 and inner legs 16. For reinforcement, a strip 22 is additionally attached to the downward-extending part of the outer leg 15, for example by gluing or welding.

FIG. 10 shows an embodiment of the stacking plate according to the invention, in which a circumferential strip 24, which extends from the plate surface 1 upwards and downwards, is applied to the circumferential edge 23 bent upwards and downwards by welding or gluing. In the example shown, this bar is bent over again in the form of a leg 25, this part being able to be glued or welded to the bar 24.

A further embodiment of the stacking plate according to the invention is shown in perspective in detail in FIG. 11. The edge 23 extending upward from the plate surface 1 is connected to a circumferential strip 26 which consists of a solid profile. The peripheral edge 23 is inserted into a recess 27 in the solid profile strip 26 and glued or welded to this strip.
