Description

The invention relates to a transport container made of a foldable blank made of cardboard, corrugated cardboard or similar foldable material, each with a portion of a container bottom defining floor sections that are hinged to the side walls of the container, the container by means of the container bottom or the bottom sections with a pallet Wood, pressed wood or similar material can be connected.

In known transport containers of this type (DE-OS 27 09 337, DE-OS 31 04 230), a first bottom portion of the container, one on the base, i.e. the part to be fastened to the pallet and two further hinged parts hinged to the first part, which are adjustable between two end positions and in their first end position enable the container body to be put on, in the first end position of the foldable parts on the top of the pallet with fastening means attached, inserted through a bottom cutout of the container into the interior thereof and, when the foldable parts are folded down, placed against a second bottom section of the container, the latter clamping the latter relative to the base. The transfer of considerable, e.g. when maneuvering and / or sudden braking during transport, forces acting on the transport container on the pallet essentially take place, at least with regard to the tilting moments and / or shear forces, via the mentioned first part of the first floor section, which has the shape of a centrally extending long one has a narrow stripe.

In order to be able to better control the high forces occurring in this very limited area, which according to statistical values of the German Federal Railways can be up to 5 times the weight in rail traffic, was compared to the earlier arrangement (DE-OS 27 09 337) with any fastening means such as conventional clamps created an improved form of attachment by means of flat-head plugs (DE-OS 31 04 230), whereby an improved security of the first floor section against tearing is achieved. Both known arrangements have in common the disadvantage that outside of this middle narrow strip, the contact between the bottom portion of the container and the pallet is achieved solely by the weight of the material stored in the container, so that due to a high center of gravity, but also with insufficient If the container is loaded or if there is an uneven load in the edge area, there is insufficient contact between the container base and the pallet and this can cause deformations in the lower edge area of the carton and thus easily damage the partially high-quality packaged goods. In addition to these when used as a result of the high loads of up to 5 times the weight of the loading unit during maneuvering and other transport and the resulting deformations, the basic concept of a first section of the floor which is provided with foldable flaps and which fastens the container requires the production of two separate sections , each for foldable blanks, which results in a higher manufacturing and storage costs. In order to be able to place the container on the pallet after the first floor section has been fastened as easily as possible and to prevent difficulties during this assembly due to the restoring forces of the wing flaps, fasteners on the wing flaps are regularly required to keep them in their first end position. Such fasteners cause further measures which are superfluous per se, for example by arranging retaining tabs or by additional ones metallic or plastic clamps, the latter having to be loosened and removed by an additional operation. Finally, the cutouts in the transverse bottom flaps of the known containers, which are required to slip the container onto the first bottom portion attached to the pallet, allow access from the outside into the interior of the container and thus pose a significant risk of theft and robbery, particularly in the case of high-quality goods to be transported These cutouts are made to the edge, so that the container is no longer completely closed to the outside, but you can easily reach inside with your hand.

The invention is based on the object to improve a transport container of the type described in such a way that the arrangement of its connection with the pallet provides increased resistance to the forces occurring (tilting moments, gravitational forces), along with simplified installation and a minimum of Available blanks and assembly means is achieved and the container also offers a closed, essentially theft-proof unit to the outside.

This object is achieved in that recesses are provided in at least one of the bottom sections lying at the top when folded, which provide access to an underlying floor section which can be placed on the pallet and a free passage for fastening means for fastening this lower floor section in the folded state of the Make a cut on the pallet bottom.

This gives you a transport container that is extremely easy to assemble and can only be attached to the surface of a pallet via its bottom sections hinged to the side walls, by first fastening the fasteners in the in the through the recesses when the blank is folded Substantially opposite bottom section are inserted, the container is then erected around the folded edge of this fastened bottom section and then the fastening means are introduced from above into a second or possibly further laterally hinged bottom sections. In this way, the container is securely fastened to the pallet in its edge regions, so that there is a significantly increased resistance to tilting moments and shear forces compared to the known containers fastened to the pallet over a central portion of the base, and the container is thus much better protected against deformation is. In addition, the container according to the invention has circumferential folding edges of the base sections, so that after it is connected to the pallet in the base area it is no longer accessible from the outside, thus forming a closed, secure unit secured against theft and robbery.

In an advantageous embodiment of the invention, the bottom sections can be provided with holes, slots or similar recesses for receiving the fastening means in the form of head plugs, preferably flat head plugs, with at least two of these holes lying under the recesses when the blank is folded together and are free of access for the fastening means. It is essential that the holes, slots or similar recesses are large enough to allow a free passage for the fastening means to the bottom section ^V lying underneath and to be able to fasten this in the folded state of the blank on the pallet without the or overlying floor sections are hindered in their subsequent unfoldability.

It is advantageous, based on the standard dimensions of pallets and containers, if at least one recess each is arranged in a first longitudinal and a transverse bottom section and when the bottom section is collapsed over holes in the opposite second longitudinal bottom portion. In this way, recesses and holes can be arranged at locations in the edge area that are favorable for fastening, in order to ensure that the container sits securely on the pallet.

Due to the measure according to the invention, the bottom sections of the container are easy to assemble and for reasons of strength in the edge area of the pallet, a substantial material saving is possible by forming the bottom sections as relatively narrow strips in relation to the total area of the pallet bottom, while covering the largely open bottom compared to the pallet and to secure against access from the outside, a floor insert that spans the pallet floor and can be placed on the floor sections can be provided. In contrast to the known, attachable floor inserts, it only needs to be a simple flat cardboard or corrugated cardboard part that is unprepared for its punching out in the correct size and that meets the requirements of simplified assembly and a minimum of Blankings and assembly materials to be kept are largely fulfilled, but at the same time increased theft security.

To further facilitate the assembly of the container on the pallet in the unfolded state of the container, a punched-out side flap hinged along an edge on the side wall can be provided in at least one of the side walls of the blank, which flap can be folded out so that it is closer to the fastening points for the Fasteners come without the person mounting the container on the pallet having to bend over the entire height of the container side walls into the interior. Therefore this will be _S eitenklappe on that container sidewall preferably provided, the fastening means are introduced only after erection of the container in its bottom edge region.

fast A particularly ha table and thus secure attachment of the container to the pallet results when the fasteners are designed as flat-headed plugs with shafts which, in a manner known per se, have the shape of crosspieces, which in turn can be provided with a sawtooth profile. The latter results in a particularly tight fit in the corresponding holes provided in the pallet, but at the same time also makes it easier to drive in such plugs as a result of the favorable deformability of the sawtooth profile in the driving-in direction while they get caught against the same in the pallet material.

1, 3 and 4, a transport container 1 can be seen, which in FIG. 1 is provided in the form of a folded corrugated cardboard blank 10, which in this position takes up a minimal transport space, but is of course also made of other suitable foldable material such as cardboard , laminated material or the like. can exist. This blank 10 includes in preparation for the final transport container shape 1 cuboid structure two longitudinal side walls 11, two transverse side walls 12, two hinged to the longitudinal side walls 11 bottom portions 13, two hinged to the transverse side walls 12 bottom portions 14 and four lid flaps 16, each in the form of two longitudinal - And two transverse side flaps, which serve to close the container. Details of the design of such a cuboid container need not be discussed here for reasons of course. Likewise, the pallet 2 is of conventional design with a pallet base 21 and footrests 22 arranged underneath it, which in the usual way allow the pallet to be passed underneath by means of an industrial truck, e.g. of a forklift.

The blank 10 in its folded form lies in FIG. 1 in such a way that it can be attached directly to the pallet 2. For this purpose, 13 fastening holes 18 are arranged in the blank in its longitudinal bottom sections. In the example shown, the container is to be fastened to the pallet 2 on each long side by means of two fastening points, specifically with the aid of flat-head plugs 3 shown in FIG 3 provided.

In order to be able to fasten the blank 21 on the pallet 2 in the collapsed state, for the purpose of access to the fastening holes 18 are to be placed in the lower one on the pallet base 21 Coming longitudinal bottom section 13 (mostly covered here) recesses 19 are provided in the overlying bottom sections 13, 14, the diameter of which corresponds at least to the largest diameter of the fastening means, for example the diameter of a flat head 31 of a flat head plug to be described in more detail in connection with FIG. 2 3. Thus, the fastening means 3 can be easily and completely inserted through the upper position of the blank 10 into the underlying holes of the longitudinal bottom section 13 in order to fasten the latter on the pallet bottom 21. The container blank can now be folded up into a cuboid around the folded edge F in the manner shown in FIG. 3, since the two upper floor sections 13, 14 are not impaired by the fastening means 3, whereupon the floor sections 13, 14 fold in inside and then the cut is erected vertically. This unfolded position is shown in Fig. 4. After reaching the second longitudinal side, the fastening means 3 required in this area are driven through the provided fastening holes 18 into the receptacles 23 in the pallet base 21, to facilitate this insertion expediently taking place after the transverse bottom sections 14 have been folded down and for this purpose at the holes 18 corresponding locations second recesses 19a are provided which correspond to the recesses 19 in terms of arrangement, function and size. After the fastening means 3 have also been inserted in this area, the transport container 1 is thus erected and can be loaded.

The fastening means shown in FIG. 2 in the form of a flat-head plug 3 is particularly well suited for this type of transport fastening on a pallet 2, for example made of pressed cardboard or wood, by providing training as a flat-head plug with flat head 31 and shaft 32, which is known as a crosspiece 33, but with a sawtooth profile 34, is formed. The latter enables the plug to be driven in easily to rest his head 33 against the top of the bottom sections, but on the other hand a firm seat against pulling out in the material of the pallet 2.

In contrast to the embodiment shown in Figs. 1, 3 and 4, in which the bottom sections are arranged substantially so substantially that they completely cover the pallet bottom 21 in the folded state and thus form the bottom surface of the container, are in the embodiment Fig. 5 bottom portions 13, 14 are provided, which are much narrower and cover only part of the container bottom. As a result of the narrower floor sections, in particular the transverse sections 14, second recesses 19a can be dispensed with in this embodiment, because the fastening holes are freely accessible from above even after floor sections 14 are completely against the pallet floor.

In order to close the container bottom, a separate bottom section 15 is provided in this exemplary embodiment, which, as a separate but unfolded stamped part, cut according to the finished container cross section, can be inserted from above into the unfolded transport container 1 attached to the pallet 2 without difficulty ( see arrow).

In this embodiment, for easier access to the interior of the container, when the fasteners 3 are inserted into a longitudinal side wall 11, a side flap 17 is provided, which carries one of the lid flaps 16 and is even articulated on the longitudinal side wall 11 from which it is punched out via a folded edge L. . Thereof after mounting of the transport container 1 in the manner described on the pallet 2 and the pivoted upright serves _S eitenklappe at the same time a erleicherten filling of the container; it can be folded up at any time, whereupon the container is then closed with a lid flap and attaching an adhesive fastener can be locked theft-proof.

It goes without saying that instead of the fastening means 3 described in the exemplary embodiments in the form of flat-head plugs, any other type of fastening means for the container blank 10 on the pallet 2 can also be used if recesses 19 are provided for the fastening method described, which provide free access to the spongy bottom section that can be placed on the pallet base 21, for example, nails or clamps can be driven through the recesses, although flat-head plugs of the type described, whether with or without a sawtooth profile 34, are preferred in view of their high fastening security. If such other fasteners are used, it is of course possible to dispense with the previous attachment of such fasteners in the pallet base 21.

It can be seen from the exemplary embodiments that the container blank 10 can be erected in an extremely simple manner and at the same time enables a simple, but particularly secured against theft fastening on the pallet.
