DESCRIPTION

Ring mounting frame as well as shipping container with a ring mounting frame

The present invention relates to a mounting frame ring for a transport container that can be arranged between a bottom of the container and a lid of the transport container, as well as to a transport container with such a mounting frame ring.

From the application DE 10 2015 120 065 A1 a transport container for the transport and/or storage of goods is known. This transport container comprises a container bottom, on which a ring composed of several side walls can be superimposed. A lid of the shipping container may be placed over the ring to close an internal space of the container. The mounting frame ring is designed so that it can be folded, so that it, for a return transport of the transport container, can be placed in a folded arrangement on the bottom of the container as well as on the lid.

From the application WO 2017063871 A1, a transport container is also known, which comprises a bottom, a mounting frame ring that can be positioned on top, as well as a lid. On a front side of a side wall a loading flap is provided for removing individual goods from the internal space of the container. The cover is supported with respect to the side wall by a flexible connecting strap, so that it can be moved from a closed position, in which the cover rests on the mounting frame ring, to an open position, in which which the cover can be positioned outside and parallel to the side wall of the mounting frame ring.

From the application WO 92/21570 A1 a transport container is known that comprises a pallet and a lid, where several open mounting frame rings can be arranged in the middle and can be stacked on top of each other. To secure transportation, circumferential tensioning bands are provided around the open mounting frame rings. To secure the cover, an external circumferential tensioning element is also provided on the upper open external ring.

From US application 4,392,606 A, a folded cardboard packaging that is held closed by circumferential tensioning bands is known as a packaging unit.

From the application DE 7929154 U1 a stackable packaging is known, where external circumferential tensioning elements are provided for fixing the goods placed on the pallet with respect to the pallet.

From application JP H04-135422 U a packaging device is known in which a lid, side walls and a pallet are supported relative to each other by external circumferential tensioning bands.

The object of the present invention is to propose a mounting frame ring for a transport container, as well as a transport container which, when filling the transport container with bulk goods, enables safe transport.

Said object is solved by a mounting frame ring according to claim 1. The mounting frame ring comprises at least one circumferential tensioning element that rests against an external side of each side wall, at least in some sections. By means of such a circumferential tensioning element it is possible to counteract a bulging or deformation of the side walls during filling of the transport container with bulk goods. Thanks to this, the shape of the mounting frame ring can be maintained when placed on the bottom of the container, in an unloaded state, after filling with bulk goods. This allows the side walls of the mounting frame ring, during use, to maintain their position with respect to the bottom of the container and possibly with respect to the placed lid. Due to this, a closed arrangement of the mounting frame ring with respect to the bottom of the container and possibly with respect to the lid can be made possible.

Advantageously, it is provided that at least one tensioning element is designed as a circumferential band or as a circumferential strap which, on each external side of the side walls, at least in some sections, extends outside, on the external side. This makes it possible to maintain the initial contour of the mounting frame ring after being placed and resting on the bottom of the container.

The circumferential tensioning element is preferably guided through recesses towards the side walls. The tension member preferably extends from an external side of the side wall, through the internal space of the container, back to the external side of the adjacent side wall. Due to this, a statically stable arrangement and alignment of the side walls with respect to each other can be made possible.

The mounting frame ring, between respectively two adjacent side walls, comprises a joint, due to which an external corner is formed. The circumferential tensioning element, within the external corner, is guided through the internal space of the container, from one side wall to another adjacent side wall. In this way, the circumferential tensioning element is guided between two adjacent side walls, namely through the internal space of the container, but this is not detrimental to the filling and/or removal of the bulk goods. Preferably, the circumferential tensioning element is guided freely within the external corner, from one side wall to an adjacent one. Thanks to this, simple conformation is possible.

The positioning of at least one tensioning element, relative to the height of the side wall, is preferably located in the central area of a mounting frame ring arranged straight or in the center with respect to the height of the side wall. According to a first embodiment, a single tensioning element is sufficient. Alternatively, two or more tensioning elements, circumferentially spaced apart, may also be provided on the mounting frame ring. For example, a central tensioning element, as well as a tensioning element can be positioned in the upper third, as well as a tensioning element can be positioned in the lower third, referred to the height of the side wall.

The circumferential tensioning element is preferably oriented in a horizontal plane, circumferentially with respect to the straight oriented side walls.

Furthermore, it is preferably provided that at least one tensioning element is arranged loosely circumferentially and guided with respect to the side walls, through the recess. This enables simple installation and cost-effective manufacturing.

In an alternative configuration of the mounting frame ring it is provided that a section of the circumferential tensioning element, which extends along the outer side of the side walls, is fixed with at least one fastening element. Thanks to this, easy manipulation of the mounting frame ring during folding can be made possible.

Advantageously, it is provided that at least one fixing element is provided at or adjacent to the joint, between the two side wall sections, of the side wall. When performing the M-folding of the mounting frame ring, to fold it, the tensioning element guided on the external side of the two sections of the side wall is necessarily guided towards the interior of the fold.

Advantageously, the circumferential tensioning element is designed as a band that is cut to size and that is designed as an endless band. Due to this, preferably, the tensioning element can surround the side walls in some sections, circumferentially loose. Thanks to this, a high holding force can be achieved by maintaining the shape of the mounting frame ring after filling.

Advantageously, the circumferential tensioning element is designed as a tensile belt. Thanks to this, the tensioning element does not get in the way when stacking the transport containers and when folding the mounting frame ring.

According to an alternative embodiment, it can be provided that the tensioning element is designed as a band or a strap, and that it has two ends that are respectively separately, but contiguously with respect to each other, fixed on the side wall, or that the two ends, one on top of the other, are fixed to the side wall. The mounting frame ring may preferably be designed by side walls which may be produced as plastic plates, multi-layer plastic plates, paper plates, corrugated paper plates or cardboard plates, or the like.

The object on which the invention is based is further solved by a transport container with a container bottom, as well as with a mounting frame ring which, in a positioned position, can be arranged on the container bottom, and with a lid which can be positioned on the mounting frame ring, wherein the mounting frame ring is designed according to one of the embodiments described above.

The invention, as well as other advantageous embodiments and improvements thereof, are described and explained in more detail below, based on the examples represented in the drawings. They show:

Figure 6 shows a perspective view of sections of the side wall of the mounting frame ring in a partially folded position.

In Figure 1, in perspective, a transport container 11 is provided for storing and/or transporting products, goods, loose cargo, in particular bulk goods. Such a transport container 11 may for example be a reusable container. It comprises a container bottom 12, as well as side walls 14, 15, 16, 17 that are formed contiguously with respect to a mounting frame ring 18. The side walls 14, 15, 16, 17, in the respective corner area, are connected to each other by a joint 19 and form an external corner 21. The number of the side walls 14, 15, 16, 17, as well as their association, is adapted to the base shape of the bottom of the container 12. In the exemplary embodiment, the bottom of the container 12 is designed in a rectangular shape, which for example corresponds to the shape of a Euro pallet. Alternatively, square container bottoms can also be provided, whereby the mounting frame ring is adapted accordingly.

The transport container 11 further comprises a lid 23 on which the mounting frame ring 18 can be placed. The bottom of the container 12, the mounting frame ring 18, as well as the lid 23, form a closed internal space of the container 24. Legs 25 are provided on the bottom of the container 12. In the exemplary embodiment, the bottom of the container 12 with the legs 25 is designed as a plastic molded part. Other alternative forms of execution, as well as materials, are also possible. Additionally, the legs 25 may also be screwed or secured with fasteners to the bottom of the container 12.

A circumferential cavity is preferably provided at the bottom of the container 12. This cavity is used to house the mounting frame ring 18, so that it is fixed in position with respect to the bottom of the container 12. The lid 23 also comprises a cavity. Thanks to this, the cover 23 can be arranged secured on the mounting frame ring 18 and can externally surround the side walls 14, 15, 16, 17.

The bottom of the container 12 and/or the lid 23, for example, may be composed of a plastic molded part. For example, these can be produced by drawing, according to the twin-sheet process. The side walls 14, 15, 16, 17 of the mounting frame ring 18 can preferably be made of plastic. Preferably, they are produced from plastic, from multi-layer plastic plates, so that they have high rigidity. For example, these side walls 14, 15, 16, 17 are composed of two outer covering layers, between which a corrugated or bubble film is provided, where the individual plastic layers are sealed with each other. Alternatively, the side walls can be made on the basis of only one layer or also on the basis of two layers.

The side walls 14, 15, 16, 17 of the mounting frame ring 18 are connected by folding edges or by a groove, by means of which the joints 19 are formed. Furthermore, preferably, it is provided that two side walls 14, 16 opposite are formed by two side wall sections 27, 28, between which another joint 19 is formed as a folding edge.

A circumferential tensioning element 31 is provided on the mounting frame ring 18. This circumferential tensioning element 31 is designed as a strap or a band. That tensioning element 31, at least in some sections, extends along the external side of each side wall 14, 15, 16, 17. The tensioning element 31 is guided from an external side of the side wall 14 towards the external side adjacent to the side wall 15, through recesses 32 in the respective side wall 14, 15; and extends between two adjacent side walls 14, 15, through the internal space of the container 24. The same also applies to the other side walls 15, 16, 17, 14. A perspective view of the ring is shown in Figure 2. mounting frame 18. That mounting frame ring 18 is shown in a partially folded state. Based on this arrangement, the M-folding of the mounting frame ring 18 results. The joint 19 formed between the two sections of the side wall 27, 28 is oriented in the opposite direction with respect to the other joints 19 at the external corners 21. Thanks to this, M-folding can be achieved. When the mounting frame ring 18 is moved into a folded position, the side wall sections 27, 28 move over each other and the tensioning element 31 is brought to a loose or relaxed position. . The tensioning element 33 therefore does not oppose the M-folding.

After folding the mounting frame ring 18, it can be placed on the bottom of the container 12 and the lid 23 can be positioned on top. Such an arrangement is shown in Figure 3. Thanks to this, a space-saving configuration of the transport container 11 for return transport can be provided. Figure 4 shows a schematic sectional view of the transport container 11 according to Figure 1. Figure 5 shows a schematic view from above of the mounting frame ring 18 according to a position of use in Figure 4.

In the representations according to Figure 4 and Figure 5, the extension and arrangement of the tensioning element 31 with respect to the mounting frame ring 18 can be seen. The tensioning element 31 is preferably designed as an endless band. This endless band is cut to size, so that this tensioning element 31 can adopt an arrangement that surrounds the mounting frame ring 18.

The tensioning element 31 is guided through the recess 32. The recesses 32, for example, are formed by perforations in the side wall 14, 15, 16, 17. These recesses 32 can also be provided with an edge for guiding the element tensioner 31 without friction and without pressure points. In the case of a side wall 14, 15, 16, 17 composed of several layers or strata, the open front side can be closed against the recess 32. The recesses 32 for guiding the tensioning element 31 are arranged near the external corner 21. Due to this, an essential part of the tensioning element 31 is guided along the external side of the respective side wall 14, 15, 16, 17. Near the external corner 21, the tensioning element 31 is guided from the recess of a side wall 14 towards the recess 32 of the adjacent side wall 15, through the internal space of the container 24. Preferably, this applies to all external corners 21. By means of this arrangement the stiffening of the side walls 14, 15 can take place. , 16, 17, so that a bulging or deformation during filling with a bulk product can be counteracted.

Advantageously, the tensioning element 31 extends over a length of two thirds or more with respect to the total length of the respective side wall, along the external side. Due to this, the section of the tensioning element 31 guided into the internal space of the container 24 can be formed short, close to the external corner 21. In Figure 6, a perspective view of the mounting frame ring 18 is shown in a partially folded position. . To improve the handling of the mounting frame ring 18 during folding, it is preferably provided that, for example, a fixing element 34 is provided on the joint 19, by means of which the tensioning element 31 is fixed with respect to the joint 19. Due to In this way, the tensioning element 31, during positioning of the mounting frame ring 18, is guided adjacent to the side wall sections 27, 28. Alternatively, the fixing element 34 may also be provided adjacent to each other. to the joint 19. For example, on each side wall section 27, 28, adjacent to the middle joint 19, such a fastening element 34 may be provided. The fastening element 34 may be a fastening flap that is fastened, stapled or sealed to the side wall 14, 15, 16, 17. The fastening element 34 may be sealing or gluing, by means of which tensioning element 31 is fixedly connected to the side wall 14, 15, 16, 17. By means of the fastening elements 34 also individual sections of the tensioning element 31 can be held fixed with respect to the respective side wall sections 27, 28.

After positioning the mounting frame ring 18 on the bottom of the container 12, preferably, a packaging sheet 35, a sack, a bag or a similar element is introduced into the internal space of the container 24. That packaging sheet 35 , the sack or bag covers the bottom of the container 12 and the internal walls of the mounting frame ring 18. They can preferably protrude above the upper edge of the mounting frame ring 18 or can be folded outwards in the upper edge of the mounting frame ring 18. The transport container 11 is then filled with bulk goods. By using the packaging film 35, the sack or the bag, the section of the tensioning element 31 led through the internal space of the container 24 can be protected near the external corner 21 and can be maintained without being influenced by the type of the bulk merchandise that must be stored. Filling and emptying of the transport container with bulk goods can also take place without hindrance.
