Description

The invention relates to a mounting ring for a transport container, which can be arranged between a container base and a cover of the transport container, as well as a transport container with such a mounting ring.

From the DE 10 2015 120 065 A1 a transport container for transporting and / or storing goods is known. This transport container comprises a container base on which a ring consisting of several side walls can be placed. A lid of the transport container can be placed on the ring in order to close a container interior. The attachment ring is designed to be foldable so that it can be placed in a folded arrangement on the container base and the lid on it for a return transport of the transport container.

From the WO 2017 063871 A1 Furthermore, a transport container is known which comprises a base, an attachment ring that can be positioned thereon, and a lid. A loading flap is provided on a front side of a side wall in order to remove individual goods from the interior of the container. The lid is held to the side wall by a flexible connecting strand so that it can be moved from a closed position, in which the lid rests on the attachment ring, into an open position, in which the lid can be positioned outside and parallel to the side wall of the attachment ring.

The invention is based on the object of proposing a mounting ring for a transport container and a transport container which enable safe transport when the transport container is filled with a bulk material.

This object is achieved by a fitting ring for a transport container, which comprises at least one circumferential clamping element which surrounds at least some sections of each outer side of the side wall of the fitting ring. Such a circumferential tensioning element enables a bulging or bulging of the side walls is counteracted when filling the transport container with a bulk material. As a result, the shape of the attachment ring when it is placed on the container bottom can be retained in an unloaded state after it has been filled with a bulk material. This enables the side walls of the attachment ring to maintain their position relative to the container base and, if applicable, relative to the attached lid during use. This enables a closed arrangement of the attachment ring to the container bottom and, if necessary, to the lid.

It is advantageously provided that the at least one tensioning element is designed as a circumferential band or a circumferential strand, which runs at least in sections on the outside of each outer side of the side walls. This enables the initial contour of the attachment ring to be retained after it has been set up and placed on the container base.

The circumferential tensioning element is preferably guided through recesses in the side walls. The tensioning element preferably extends from an outside of the side wall through the container interior back to the outside of the adjacent side wall. This enables a statically stable arrangement and alignment of the side walls with respect to one another.

The Aufsetzring comprises a joint between two adjacent side walls, whereby an outer corner is formed. The circumferential tensioning element is preferably guided within the outer corner through the container interior from one side wall to the other, adjacent side wall. As a result, the circumferential tensioning element is guided through the interior of the container in the corner area between two adjacent side walls, but this is not impaired for the filling and / or removal of the bulk material. The circumferential tensioning element is preferably guided freely within the outer corner from one adjacent side wall to the other. This enables a simple design.

The positioning of the at least one clamping element based on the The height of the side wall is preferably in the middle area of an upright attachment ring or in the middle of the height of the side wall. According to a first embodiment, a single tensioning element is sufficient. Alternatively, two or more clamping elements can also be provided circumferentially at a distance from one another on the attachment ring. For example, a central tensioning element and a tensioning element in the upper third and also a tensioning element in the lower third can be positioned in relation to the height of the side wall.

The circumferential tensioning element is preferably aligned in a horizontal plane circumferentially with respect to the upright side walls.

Furthermore, it is preferably provided that the at least one tensioning element is arranged loosely circumferentially and guided through the recess to the side walls. This enables simple attachment and inexpensive manufacture.

An alternative embodiment of the attachment ring provides that a section of the circumferential tensioning element, which extends along the outside of the side walls, is fixed with at least one fixing element. This allows easy handling of the attachment ring when it is folded.

It is advantageously provided that the at least one fixing element is provided on or adjacent to the joint between the two side wall sections of the side wall. When performing the M-fold of the attachment ring in order to collapse it, the tensioning element guided on the outside of the two side wall sections is forcibly guided into the fold.

The circumferential tensioning element is advantageously designed as a belt which is cut to size and designed as an endless belt. As a result, the tensioning element can preferably encompass the side walls in sections around the circumference. In this way, a high holding force can be achieved while maintaining the shape of the attachment ring after filling.

The circumferential tensioning element is advantageously used as a tensile strength Belts trained. As a result, the clamping element does not interfere with the stacking of the transport containers and the folding of the attachment ring.

According to an alternative embodiment it can be provided that the tensioning element is designed as a band or strand and has two ends which are each fastened separately but adjacent to one another on the side wall, or which are fastened with the ends one above the other on the side wall.

The attachment ring can preferably be formed by side walls, which can be made as plastic sheets, as multilayer sheets made of plastic, from paper sheets, corrugated paper sheets, cardboard sheets or the like.

The object on which the invention is based is furthermore achieved by a transport container with a container bottom and a fitting ring which can be arranged in an erected position on the container bottom and with a lid which can be positioned on the fitting ring, in which the fitting ring according to one of the above Embodiments is formed.

In Figure 1 a transport container 11 for storing and / or transporting goods, goods, piece goods, in particular bulk goods, is provided in perspective. Such a transport container 11 can be, for example, a reusable container. This comprises a container bottom 12 and side walls 14, 15, 16, 17, which are designed to be connected to form a fitting ring 18. The side walls 14, 15, 16 are connected to one another in the respective corner area by a hinge 19 and form an outer corner 21. The number of side walls 14, 15, 16, 17 and their assignment is adapted to the basic shape of the container bottom 12. In the exemplary embodiment, the container bottom 12 is rectangular, which corresponds, for example, to the shape of a Euro pallet. Alternatively, square container bottoms can also be provided, after which the attachment ring is adapted accordingly.

The transport container 11 furthermore comprises a cover 23 which can be placed on the attachment ring 18. The container base 12, the attachment ring 18 and the cover 23 form a closed container interior 24. Feet 25 are provided on the container base 12. In the exemplary embodiment, the container bottom 12 with the feet 25 is designed as a plastic molded part. Further alternative embodiments as well as materials are also possible. Furthermore, the feet 25 can also be screwed or clipped onto the container bottom 12.

A circumferential depression is preferably provided on the container bottom 12. This recess serves to receive the attachment ring 18, so that it is arranged in a fixed position in its position relative to the container base 12. The cover 23 also includes a recess. As a result, the cover 23 can be arranged securely on the attachment ring 18 and encompass the side walls 14, 15, 16, 17 on the outside.

The container bottom 12 and / or the lid 23 can consist of a plastic molded part, for example. These can be produced, for example, by deep drawing using the twin-sheet process or the like. The side walls 14, 15, 16, 17 of the Aufsetzringes 18 can be preferably made of plastic. These are preferably made from multilayer plastic sheets so that they have a high degree of rigidity. For example, these side walls 14, 15, 16, 17 consist of two outer cover layers between which a corrugated or knobbed film is provided, the individual layers of plastic being welded to one another. Alternatively, the side walls can be formed from only one layer or from two layers.

The side walls 14, 15, 16, 17 of the Aufsetzringes 18 are connected by folded edges or by a grooving through which the joints 19 are formed. Furthermore, it is preferably provided that two mutually opposite side edges 14, 16 are formed by two side wall sections 27, 28, between which a further joint 19 is formed as a folded edge.

A circumferential clamping element 31 is provided on the attachment ring 18. This circumferential tensioning element 31 is designed as a strand or a band. This clamping element 31 extends at least in sections along the outside of each side wall 14, 15, 16, 17. The clamping element 31 is passed from one outside of the side wall 14 to the adjacent outside of 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 container interior 24. The same also applies to the further side walls 15, 16, 17, 14.

In Figure 2 is a perspective view of the Aufsetzringes 18 shown. This Aufsetzring 18 is shown in a partially folded state. The M-fold of the attachment ring 18 emerges from this arrangement. The joint 19 formed between the two side wall sections 27, 28 is oriented in the opposite direction to the further joints 19 on the outer corners 21. This enables the M-fold to be achieved. When the attachment ring 18 is transferred into a collapsed position, the side wall sections 27, 28 are moved towards one another and the tensioning element 31 is brought into a loosened or relaxed position. The tensioning element 33 thus does not stand in the way of the M-fold.

After the attachment ring 18 has been folded up, it can be placed on the container base 12 and the lid 23 positioned on it. This arrangement is in Figure 3 shown. As a result, a space-saving design of the transport container 11 can be given for the return transport.

In Figure 4 FIG. 11 is a schematic sectional view of the transport container 11 according to FIG Figure 1 shown. The Figure 5 FIG. 11 shows a schematic view from above of the attachment ring 18 according to a position of use in FIG Figure 4 .

From the representations according to Figure 4 and 5 shows the course and the arrangement of the tensioning element 31 in relation to the attachment ring 18. The tensioning element 31 is preferably designed as an endless belt. This endless belt is cut to size so that this tensioning element 31 can assume an arrangement that encircles the attachment ring 18.

The tensioning element 31 is guided through the recess 32. The recesses 32 are formed, for example, by punchings in the side wall 14, 15, 16, 17. These recesses 32 can also be provided with an edge in order to guide the clamping element 31 with little friction and without pressure points. In the case of a side wall 14, 15, 16, 17 consisting of several layers or plies, the open end face at the recess 32 can be closed.

The recesses 32 for guiding the clamping element 31 are arranged near the outer corner 21. As a result, a substantial part of the tensioning element 31 is guided along the outside of the respective side wall 14, 15, 16, 17. Close to the outer corner 21, the tensioning element 31 is passed through the container interior 24 from the recess in one side wall 14 to the recess 32 in the adjacent side wall 15. This preferably applies to all outer corners 21. This arrangement allows the side walls 14, 15, 16, 17 to be stiffened so that bulging or bulging can be counteracted when filling with bulk material.

The tensioning element 31 advantageously extends over a length of two thirds or more of the total length of the respective side wall along the outside. As a result, the section of the tensioning element 31 passed through the container interior 24 near the outer corner 21 can be made short.

In Figure 6 is a perspective view of the Aufsetzringes 18 shown in a partially collapsed position. To improve the handling of the attachment ring 18 while it is being folded up, provision is preferably made for a fixing element 34, for example, to be provided on the joint 19, by means of which the tensioning element 31 is fixed to the joint 19. As a result, the tensioning element 31 is guided in contact with the side wall sections 27, 28 during the folding together of the attachment ring 18. Alternatively, the fixing element 34 can also be provided adjacent to the joint 19. For example, such a fixing element 34 can be provided on each side wall section 27, 28 adjacent to the joint 19 lying in between. The fixing element 34 can be a fixing tab which is pushed, clipped or welded onto the side wall 14, 15, 16, 17. The fixing element 34 can also be a weld or an adhesive, by means of which the tensioning element 31 is firmly connected to the side wall 14, 15, 16, 17. By means of the fixing elements 34, individual sections of the tensioning element 31 can also be held fixed to the respective side wall sections 27, 28.

After the positioning ring 18 has been positioned on the container base 12, a packaging film 35, a sack or a bag or the like is preferably inserted into the container interior 24. This packaging film 35, the sack or the bag line the container base 12 and the inner walls of the attachment ring 18. This can preferably protrude beyond the upper edge of the attachment ring 18 or be turned over to the outside at the upper edge of the attachment ring 18. The transport container 11 is then filled with bulk material. By inserting the packaging film 35, the sack or the bag, the section of the Clamping element 31 be protected near the outer corner 21 and remain unaffected by the type of bulk material to be picked up. Unhindered filling and emptying of the transport container with bulk material can also take place.
