Pallet, transport container or the like.

The innovation relates to a pallet, transport container Od. The like., With arranged on the floor collapsible, made of corrugated cardboard Honlbalken, in the Stiffening elements can be inserted.

In the case of the known pallets, transport containers and the like of the above-mentioned type, stiffening elements! Cardboard strips used. These can have different cross-sectional shapes have, but cardboard strips with a V-shaped cross-section are usually used. tuck Cardboard strips have the advantage that they take up little space, but on the other hand they are not very stable and can give way easily with larger loads. Therefore, with additional cardboard strips to be inserted stiffening hollow beams are only provided for relatively small pallets and transport containers that are used for the They are intended to accommodate correspondingly lower loads «In particular, for this reason, the inserted | Cardboard strips did not stiffen hollow beams with such large ones

Pallets and transport containers are used that can only be moved with a forklift. Apart from that, the support, which is made entirely of cardboard, also has the disadvantage that it is sensitive to moisture reacts very sensitively by quickly softening on contact with water and finally collapsing.

Furthermore, when inserting the cardboard strips, ensure that the cardboard strips are correctly oriented in the cardboard feet will. For static reasons, for example, with a V-shaped cardboard strip it is necessary that the point is pointing upwards points, while the legs grip into the lower edges of the hollow beam. Otherwise the resilience of the cardboard feet would be be reduced.

The innovation is therefore based on the task of the object of use of the type mentioned in such a way that it is simple, reliable and easy to use for sure is.

According to the innovation, this object is achieved in that the stiffening elements are stable molded bodies, the cross-section of which is adapted to that of the hollow beam. Obviously, all of the above-mentioned disadvantages in the prior art are avoided in one fell swoop. The moldings are extremely stable and suitable for carrying large loads, insensitive to moisture and can - because you Cross-section to which the hollow beam is adapted - not be used incorrectly oriented. In particular, due to the as Stiffening elements designed as molded bodies are also created as large pallets, transport containers and the like that be considered for movement with the forklift.

According to a special design of the innovation the cross-sectional shape of the hollow beams and the molded bodies to be inserted therein are rectangular, with a view to for optimal support of the load, the width of the molded body and the hollow beam is greater than their height is chosen.

The shaped body can be a solid body or a body interspersed with cavities, similar to a hollow brick.

The molded bodies used as stiffening elements are advantageously made of foamed plastic. They are then not inferior to the cardboard strips in terms of their weight. It has proven to be beneficial when the moldings are made of expanded polystyrene. In this context it should be noted that Hollow beams made of cardboard or cardboard sleeves connected to the pallet or the transport container are absolutely necessary, if foamed plastic bodies are used, because foamed plastic is difficult to nail or glue, so it is not directly secure to that Pallet floor or transport container floor can be attached.

To increase the safety and reliability of the support, it is also useful to use the cardboard Waterproofing hollow beams.

In terms of production technology, the Hollow beam for receiving the molded body in a cardboard transport container with four wall elements, each of which has a

nen ceiling section, a side wall section and a Has bottom section, which are separated by fold lines, then formed if according to a further embodiment the innovation, the folded-over bottom section of the first wall element forms an inner bottom cardboard layer of the container, the folded-over bottom sections of the second and third wall element facing the other for folding around two further parallel folding lines each one of the hollow beams running along a bottom edge of the container and partially form an intermediate bottom cardboard ply resting on the inner bottom paperboard, and when the folded over The bottom section of the fourth wall element is an outer bottom cardboard ply resting on the intermediate bottom cardboard ply forms.

The cardboard layers folded on top of one another can thereby be combined with one another stapled and / or glued.

Furthermore, in this transport container according to another Feature of the invention of the side wall section of the first and / or the fourth wall element on the hollow beam associated corners extensions to at least partially cover the open sides of the folded-over bottom, the sections of the second and third wall elements have hollow beams formed.

These extensions are preferably made as a right triangle formed, the cathode of the triangle with the fold lines or the side edges of the respective side wall section align and the hypotenuse coincides with the diagonal of the hollow beam.

A high level of stability of the hollow beams is achieved by these extensions. The processes take especially the transverse to the hollow beam and outwardly directed forces on the outer wall when the transport container is loaded of the hollow beam and cause tearing

long the vertical edges or the folding lines of the transport container designating the side wall sections, since it connects the outer lower corner of the hollow beam with the inner upper corner of the hollow beam precisely because of a displacement the walls of the hollow beam and thus the middle cardboard layer is counteracted, connect. On a staple or gluing the floor cardboard layers can therefore be dispensed with. At the same time, the appendages also support them vertically Direction off. The extensions also serve as stops for the stable molded body to be inserted into the hollow beam. If the extensions are only provided at one of the ends of the hollow beams, the molded bodies can be attached to each the other end of the hollow beam can be pushed into and out of this. However, if they are at both ends of the hollow beams are present, the moldings must obviously be provided during the folding.

Further advantages, features and details of the innovation emerge from the following, using the enclosed Drawing following description of several exemplary embodiments. In the drawing show:

Figure 4b shows the cut of the cardboard sheet for the production of the Transport container shown in Figure 4a.

The pallet shown in Figure 1a has a rectangular base 10, two longitudinal side walls 12 ', 12 "and two transverse side walls 14', 14". The cut of the corresponding cardboard sheet is shown in FIG. 1b. According to this, a rectangular cardboard sheet 16 has four folding lines 18, each at a distance corresponding to the width of the side walls 12 ', 12 ", 14' and 14", running parallel to its edges, the cardboard sheet 16 along those folding lines 18 which are necessary for the formation of the Transverse side walls 14 'and 14 "are responsible, up to the folding lines 18 running transversely to them. This creates flaps 20 at the corners of the rectangular cardboard sheet 16, which are formed in one piece with the transverse side walls 14', 14" and after folding by stapling or glued to the long side walls. The pallet produced in this way is then provided with hollow beams 24 made of cardboard along its transverse side walls 14 ', 14 ", for example using heft clamps 22.

In Figure 2, such a hollow beam 24 made of cardboard is shown. The hollow beam 24 is square in cross section and is supported by a rectangular cardboard strip .mit four evenly spaced from one another and from the edges arranged parallel fold lines 24a and 24b by folding generated. One side of the hollow beam must then have a double layer. With this side the hollow beam is attached to the Bottom 10 of the pallet or other transport container

7736924 23.0178

with the help of the staples 22 attached, which at the same time the two superimposed cardboard layers of the hollow beam 24 hold together and thus secure the hollow beam against opening. By folding it over along the fold lines 24a to 24d, however, the empty hollow bar can be pressed flat at any time when not in use. To stiffen the hollow beam Made of cardboard when used, the innovation is a more stable one Molded body 26, preferably made of expanded polystyrene, the cross-section and length of which are each equal to the cross-section and the Length of the erected hollow beam and thus fills the entire hollow beam.

In Figure 3a, the feet according to the innovation are connected shown with a transport and display container. This container consists of three separate parts 28, 30 and 32. The part 28 comprises a container bottom 34, two side walls 36 and a rear wall 38. On the one opposite the rear wall 38 The U-shaped folded part 32 can be used on the side. The part 30, which is basically the same shape as the pallet shown in FIG. 1 a has, can then be placed as a cover on the parts 28 and 32 which are fitted into one another will. With the help of a shrink film, the three parts 28, 30 and 32 can be held together for transport will. For the display of the goods, the cover 30 and the part 32 are removed after removing the shrink film, so that the viewer has a clear view of the container.

The blank of the cardboard sheet forming part 28 is shown in FIG Figure 3b shown. The cardboard sheet has two parallel fold lines 40 to form the side walls 36 and the rear wall 38 on. A fold line 42 running perpendicular to this is used to form the bottom 34. Incisions made by the Bottom 34 associated side are made along the fold lines 40 ensure with the side walls 36

lumpy connected tabs 36 "when folding the cardboard sheet come to rest on the section forming the bottom 34 and integrally connected to the rear wall 38 and with stapled or glued to this. The free upper edge of one or both side walls 36 can be used for a better View and access to the goods located in part 28 be beveled.

Hollow beams 24 made of cardboard are arranged on the container bottom 34, which are similar to the cabbage bars described in connection with FIG. 1a and FIG. In the "embodiment shown here three hollow beams 24 are provided, two of which adjoin the side walls 36 and run parallel to them and the third is arranged in the middle of the container bottom parallel to the other two »

In Figure 4a, a collapsible transport container is from Cardboard shown, which is characterized in that it including the hollow beams in one piece from a cardboard sheet is made. In Figure 4b, the blank and the fold lines of the cardboard sheet are shown. Four wall elements 41, 42, 43 and 44 are separated from one another by fold lines 45. The wall elements 41, 42, 43 and 44 each have a ceiling; section 46, 47, 48 and 49, a side wall section 50, 51, 52 and 53 and a bottom section 54, 55, 56 and 57 on. The ceiling sections 46, 47, 48 and 49 and the floor sections 54, 55, 56 and 57 are from the side wall sections 50, 51, 52 and 53 separated by fold lines 58. The cover sections 46, 47, 48 and 49 form the cover of the transport container. Three fold lines 58 separate the bottom sections, respectively 55 and 57 from the associated side wall sections 51 and 53. By folding around these three fold lines, the Hollow beam 59 formed.

The transport container in Figure 4a is made from the cardboard sheet shown in Figure 4b as follows: First

7736924 23.oa78

the outer side edges 60 of the side wall sections 50 and 53 connected to one another with simultaneous folding along the fold lines 45, so that a rectangular cross-section The shell is open on both sides but closed in the circumferential direction. The bottom of the shipping container will formed by three layers of cardboard one on top of the other. Therefor the bottom section 54 is angled by 90 ° around the fold line 58. The bottom section 54 forms the inner bottom cardboard ply of the finished transport container. Then the bottom sections 55 and 57 are assigned by the -three, respectively Fold lines 58 folded at right angles, whereby the hollow beams 59 along the side wall sections 52 and 53 are created as well as two in the finished container as an intermediate floor cardboard layer appearing flaps extending inwardly from the hollow beams 59 and on the bottom portion 54 rest. Finally, the bottom section 56 of the side wall section 52 is associated with it Faltliuie 58 folded over and forms the outer cardboard layer of the transport container. The bottom portion 56 comes to lie between the hollow balconies59 and is therefore at least narrower by twice the width of the hollow balcony59 than the floor section 54 forming the inner floorboard ply. The three floorboard plies can be secured by suitable fastening means be held together.

The lid of the shipping container is then through the four Ceiling sections 46, 47, 48 and 49 formed in a known manner.

According to a further feature of the invention are on the side wall sections 50, 52 of the first and fourth wall elements 41, 43 at the corners associated with the hollow beams 59 Projections 61 are provided, as shown in Figures 4a and 4b. These projections have the shape of a right-angled Triangle, the sides of which with fold lines 45, 48 or

773S924 2 3.0a78
