Description

Container frames for use with a pallet to form a storage and transport container

The present invention relates to a container frame for use with a pallet for forming a storage and transport container from a foldable blank made of recyclable material, such as e.g. Solid cardboard or corrugated cardboard. The invention further relates to a pallet and to a storage and transport container.

From US-A-2, 762, 551 a container is known which has an inner and an outer container wall. At the lower end there is a bottom with an edge which is inserted between the two container walls. A lid is attached to the upper end of the container and is inserted with side edges between the container walls. The container can be made of fiberboard, corrugated fiberboard or another suitable material. The floor is placed on a pallet, for example made of wood, whereupon the inner container wall is placed on the floor. The outer container part is then placed on the pallet. This container has the disadvantage that two separate container walls have to be placed one after the other on the pallet. Furthermore, a separate bottom part is necessary.

It is therefore an object of the present invention to provide a container frame for forming a storage and transport container, which can be attached to a pallet with simple handles. this will achieved according to the invention by the characterizing features of claims 1 or 2.

In a preferred embodiment, there should be the possibility that several container frames can be put on top of one another and, if desired, can be closed at the top with a lid. This is achieved according to the invention by the features of claims 3 and 4.

It is also an object of the present invention to provide a pallet for use with a container frame. According to the invention, this is achieved by the features of patent claim 6.

Furthermore, it is an object of the present invention to provide a method for producing the container according to the invention. According to the invention, this is achieved by the features of patent claim 9.

Furthermore, it is an object of the present invention to provide a storage and transport container, the container frame of which can be attached to a pallet in a simple manner and which has no parts which are not recyclable. According to the invention, this is achieved by the features of patent claim 10.

Due to the three-layer design, the container frame is very stable and is also suitable for large storage and transport containers. Because the container frame consists of solid cardboard or corrugated cardboard and adhesive, it is recyclable.

Exemplary embodiments of the invention and their use are described in more detail below with reference to the accompanying drawings. 1 shows a perspective exploded view of the container frame with pallet and lid, FIG. 2 shows a section along line II-II of FIG. 1, but with the container assembled, Fig. 3 shows a section in the area of two put together

The container frame 1 of FIG. 1 is made up of three mit¬ mutually bonded layers 2, 3 and 4 from aufge¬ ^'box builds, wherein the middle layer has a lower -3 width and thickness respectively as the inner layer .2. the outer layer 4. The middle layer 3 is on both sides of the edge of the inner layer 2, respectively. the outer layer 4 set back and thereby forms a slot 5 at the top and bottom of the container wall. 6. The container frame comprises four wall elements 55, 56, 57, 58. A pallet 7, which forms the bottom of the container, comprises a base plate 8, which is glued from individual cardboard sheets. DOWN to the base plate 8 are adhered nine cardboard foot ^pieces' 9, which board foot pieces are cut out from sheets consisting of a plurality of cardboard sheets glued ^"are. Depending on the requirements for Er¬ submission of an additional gain of three patent crisps feet -9 means A base element 10 is glued to the side of the base plate 8 opposite the feet 9, the edges 11 of which are bent upwards, and the lower frame of the container frame 6 is inserted onto the edge 11 of the pallet 7 To close the container, a slot 5 can be inserted into the upper slot Cover element 12 made of cardboard are inserted, which also has bent edges 13 like the base element 10. A hand hole can be arranged in the cover element 12 for better removal thereof from the container frame.

FIG. 2 shows a section along line II-II of FIG. 1, but in contrast to FIG. 1 the container frame 1 is placed on the pallet 7 and the cover 13 on the container frame 1. The inner layer 2 and the outer layer 4 of the wall elements consist of glued cardboard and the middle layer 3 of kraft¬ laminated insert cardboard. Four wall elements on the long side, four wall elements on the transverse side and an interlayer on force-laminated cardboard are required for a container. The base plate 8 consists of a cardboard plate, sheet-glued from cardboard sheet 14. The foot pieces are sawn out of ten plates 15 glued together. The base element 10 glued onto the base plate 8 consists of gray cardboard laminated on both sides with highly tear-resistant kraft paper, which is grooved in the edge areas so that the edges 11 can be set up. The cover element 12 is made of the same material and in the same way as the base element 10.

The foot pieces 9 could be provided with a pin 63 which is embedded in a punched-out opening 64 in the base plate 8. A foot piece with a pin can be produced, for example, by gluing two more plates together and milling the pin 56 out of the sawn-out foot piece. In Fig. 3 is a section in the upper area of a

Container frame 1 is shown, on which an additional container frame 15 is placed. The upper container frame 15 is of the same design as the lower container frame 15. holder frame 1 and also has side walls with three layers 16, 17 and 18. A cardboard belt 19 is inserted into the upper slot 5 of the lower container frame 1. On this cardboard belt 19, which protrudes above the upper edge 20 of the lower container frame 1, the lower insertion slot 21 of the upper container frame 15 is placed. In this way it is possible to vary the height of the entire container. A cover element is then inserted in the upper plug-in slot of the upper container frame, which cannot be seen in FIG. 3, in the same way as shown in FIG. 2.

In the following it will be explained with reference to FIGS. 4-9 how the container frame 1 is manufactured. A first longitudinal and a first transverse wall elements 22 and 23, which have an adhesive application on the surface, are placed next to one another at a distance. (Fig. 4).

On top, i.e. an insert carton 24 is placed on the adhesive application of the wall elements 22 and 23 (FIG. 5). Opposite the wall elements 22 and 23, a second longitudinal and a second transverse element 25 and 26 are placed on the insert cardboard 24 with a glue application underneath and glued to the insert cardboard 24 by pressing (FIG. 6). A third transverse element 27 is placed flush on the longitudinal wall element 25 with the outer edge and a third longitudinal wall element 28 is also placed flush on the transverse element 26 also with the outer edge, these wall elements 27 and 28 having a glue application on top (FIG. 7). The protruding areas 29 and 30 of the insert carton 24 are placed on the wall elements 27 and 28 (FIG. 8).

Opposite the cross member 27 and the longitudinal element element 28, a fourth transverse element 31 and a fourth longitudinal element 32 with adhesive application are placed on the folded areas 29 and 30 of the insert carton (FIG. 9). Then the superimposed wall elements with the insert cardboard running in between are pressed to create a good bond.

The collapsed container frame can be seen from FIG. In this condition, the container frames can be stacked and delivered as a package. The pallets 7 can also be stacked on top of each other and delivered separately from the container frames. As already in the. Explanations given for FIG. 2, the pallets and the container frames preferably have dimensions that correspond to the European standard format. The box for the manufacture of the base plate and the feet can be surface-glued with a size press in order to achieve a certain resistance against the ingress of water. The container frame, the pallet and the lid can also be made hydrophobic in other ways so that they are not softened in the rain.

All components of the container, including the pallet and the lid, consist only of cardboard or. Solid board or corrugated board, i.e. Fiber material and adhesive, and are therefore well suited for recycling, i.e. they can be used again for the production of cardboard. If the container is defective, it can, for example, be filled with waste fiber material and processed again into cardboard mass. Old used containers can also be filled with waste and sent to the refuse.

This four wall elements 59, 60, 61, 62 um- Containing container frame 33 is also constructed in three layers, the three layers being made of solid cardboard. The frame is produced in the same way as was explained with reference to FIGS. 4-9 in the first exemplary embodiment. The outer layer 34 protrudes at its lower edge 35 over the middle layer 37. The inner and middle layers 36 and 37 are extended at the upper edge 38 by the same amount beyond the outer layer 34 as the outer layer protrudes downwards at its lower edge from the middle layer 37. The inner layer is at the bottom of the B ^'ehäl- terrahmens 33 ausverlängert lobular -hin¬ over the middle layer, said flap -werden- bent by 90 ° and get the gene is not shown in Fig. 10 range to Lie. The flaps 39, 40, 41 and 4-2 are cut in the corners of the container frame at an angle of 45 °. The edge 35 of the outer layer 34, which is extended at the lower edge of the container frame 33, is placed over the pallet. Another identical container frame or a lid can be placed on the container frame 33.

FIG. 11 shows a section through the container frame 33 placed on a wooden pallet 41. The lower, tab-shaped edges 39 of the ^" inner layer 36 bent over by 90 ° are placed on the pallet base 44. The lower part 35 of the outer layer 34 protrudes over the pallet base 44 and thus secures the container frame 33 on the pallet 43 The outer layer 46 of a second container frame 47 lies on the edge 45 of the outer layer 34. The inner layer 48 and the middle layer 49 of the upper container frame 47 lie on the upper edge 38 of the inner layer 36 and the middle layer 37 of the lower container frame 33. In in the same way, a lid could also be placed on the lower container frame 33 or additionally on the upper container frame 47. There is also the possibility of placing more than two container frames on top of one another. The inner layer 48 of the upper container frame 47 can also be extended in the form of a tab.

FIG. 12 shows a section through the side wall 48 of a container frame of a third exemplary embodiment. As in the second exemplary embodiment, the outer layer 49 is also offset with respect to the middle and the inner layer 50. The middle layer consists of three individual layers 51, 52 and 53. The tabs 54 for laying on the pallet base are arranged between two layers 52 and 53 of the middle layer and are also bent by 90 °, as in the second exemplary embodiment.

In ^"another, not shown, the fourth Aus¬ are exemplary implementation of the three layers 34, 36 and 37 at the top of the same height, which in this exemplary embodiment then play no second frame could be attached. The edge of the lid would, in this case via the outer layer 34 turned over.

The second, third and fourth exemplary embodiment are preferably used when conventional wooden pallets are to be used further.
