EP3750822B1 - Sleeve for a transport container and transport container - Google Patents

Description

The invention relates to a mounting ring for a transport container and a transport container which is intended for transporting goods.

From the DE 10 2015 105 030 B3 a transport container is known which is designed as a collapsible container. This container consists of a base, a lid and a mounting ring arranged between them, which is formed, for example, from four side walls. For the return transport of such transport containers after the goods have been delivered, the attachment ring can be folded up and placed on the floor, so that the lid then rests on the floor with the attachment ring interposed.

From the DE 10 2004 010 237 A1 a mounting ring for a transport container is known. This attachment ring includes two ring sections. A holding profile is pressed onto each end face of the ring section. For this purpose, the holding profile has a U-shaped receptacle through which the front edge is encompassed on the outside. Furthermore, the holding profile has a flexible leg. The opposite ring sections are held together by a snap connection via the flexible legs arranged on the holding profile.

From the US 2005/0199623 A1 Transport containers are also known in which such attachment rings are designed in two or more parts and are divided into ring sections. As a result, for example, a ring section, which includes a front side wall and a side wall section, can be removed, with a further ring section, which includes at least the rear wall, remaining placed on the floor in order to protect the goods stored on the floor. Nevertheless, the goods are accessible from the front. The ring sections forming the attachment ring are connected to one another using Velcro fasteners.

Instead of using Velcro fasteners is from the US 2011/0132801 A1 known to use magnets.

From the EP 3 354 586 A1 is a transport container consisting of a pallet, several stackable mounting rings and a lid. The attachment rings are designed as closed rings and these can be folded together using a so-called M-fold. For stacking the attachment rings one on top of the other, several attachment profile elements are provided, which connect an upper end face of a lower attachment ring with a lower end face of a attachment ring stacked above it.

The invention is based on the object of proposing a mounting ring for a transport container and a transport container which enables a simple construction of the mounting ring and a simple transfer into a position of use for unloading goods or items.

This object is achieved by a mounting ring for a transport container according to the features of claim 1. The at least two ring sections, which form a closed attachment ring, have an end edge at the respective end of the ring sections, which extends between an upper and lower end face of the ring sections and can be connected to one another by a holding profile, the main profile being the opposite end edges of the two adjacent ones Receives ring sections and aligns them with each other. The holding profile can be easily attached to an end edge of one ring section and this ring section can be positioned on the floor. The front edge of the further ring section can then also be connected to the holding profile and placed on the floor. As a result, a closed attachment ring can be created in a simple manner by assembling the at least two ring sections. The same applies to removing one ring section from the other ring section. This enables short setup and dismantling times.

The holding profile has a first U-shaped receptacle and, opposite it, a second U-shaped receptacle, which runs along are aligned with a common outer leg. As a result, when the respective adjacent end edges of the side sections of the ring section are inserted into the holding profile, an aligned arrangement of the outer sides of the side wall sections can be created with one another. Also, only a small projection beyond the outside of the side wall sections can be achieved by the outer leg located on the outside. As a result, the attachment ring formed by the ring sections can be inserted together with the holding profile into a groove on the floor and secured therein.

Furthermore, a locking element pointing into the U-shaped receptacle, preferably a locking lug, is preferably provided, which can be locked with a locking element provided on the front edge of the side wall section of the ring section. As a result, the holding profile can be held on a ring section by a plug-in locking connection. Opposite, the U-shaped receptacle of the holding profile can only be designed as a plug-in connection with the end edge of the adjacent ring section.

Furthermore, the at least one side wall section and/or the side wall of the ring section is preferably formed from a multi-layer plate, in particular a hollow chamber plate or three-layer plate. The front edge is reduced in thickness compared to the thickness of the side wall section of the side wall. As a result, a connection point can be created with the holding profile, which only corresponds to the thickness of the side walls or only protrudes slightly and on one side relative to an inside or outside of the side wall sections or side walls. The ring sections can be made from so-called hollow chamber plates or triplex plates, which have high rigidity. This means that the load capacity can be increased even when transport containers are stacked on top of each other.

Furthermore, the front edge of the side wall section is formed by heat forming and the front edge is aligned centrally to the thickness of the side wall section or aligned to the outside of the side wall section, so that a wall section of the Front edge lies in the extension of a flat section of the side wall. This enables inexpensive production while maintaining a closed side wall, especially when using so-called hollow chamber panels.

Furthermore, the U-shaped receptacle of the holding profile with the locking element preferably has a width that corresponds to the wall thickness of the front edge. This allows the holding profile to be accommodated and arranged precisely on one ring section.

Furthermore, the U-shaped receptacle, which lies opposite the receptacle with the locking element, preferably has a width that is greater than the wall thickness of the end edges. This allows the front edges to be easily threaded or inserted into the hollow profile. The width of this U-shaped receptacle preferably corresponds to twice the wall thickness of the front edge.

According to the invention, the width of the U-shaped receptacles of the holding profile is narrower than the thickness of the side wall sections. As a result, an inner volume of the transport container can be formed exclusively by the inner surfaces of the ring sections, and the holding profile does not protrude into the interior compared to these inner surfaces.

Furthermore, the respective inner legs of the U-shaped receptacle of the holding profile preferably have a length which corresponds to the width of the wall section of the front edge, which is reduced in thickness compared to the side wall sections, or is designed to be shorter. As a result, with the same length of the inner leg and width of the wall section of the front edge, additional support of the side wall section can be provided on the inner legs of the U-shaped receptacle.

Advantageously, one ring section of the attachment ring is designed as a so-called U-ring, which comprises a rear wall and a side wall section adjacent to it, which are preferably connected in one piece to the rear wall by hinges. Such a U-ring can be easily folded. This one can too be placed on a floor, especially in a groove in the floor.

Furthermore, the at least one further ring section is designed as a so-called C-ring, which has a front side wall and a side wall section adjacent to it laterally, which are preferably connected in one piece to the front side wall with a hinge. The C-ring differs from the U-ring in that the side wall sections of the C-ring are preferably shorter than those of the U-ring. For example, the width of the sidewall portions of the C-ring is one-third the length of a sidewall, and the sidewall portions of the U-ring comprise two-thirds of the corresponding sidewall. The two side wall sections are preferably designed to have the same position. As a result, with a mounting ring consisting of two ring sections, the connection points are in one plane, and the ring sections can be sprayed onto the floor without a specific orientation.

A locking element, in particular a recess, is preferably provided on the respective end edge of the U-ring, so that the holding profile with the U-shaped receptacle, which has the locking element, is held by a plug/locking connection. The respective end edges of the C-ring are preferably designed to be free of locking elements. These only form a plug-in connection with the U-shaped receptacle of the holding profile. This means that the retaining profile can remain on the U-ring when the attachment ring is assembled or dismantled. This makes handling easier. Thus, on the one hand, the C-ring can be removed in a simple manner, with the U-ring remaining on the floor in order to protect the goods or goods still stored on the floor of the transport container for successive removal. On the other hand, simple handling can be made possible in order to separate ring sections from one another in order to then fold them up for return transport.

The object on which the invention is based is further achieved by a transport container with a base and a lid and a mounting ring arranged between them consisting of at least two Ring sections solved, the attachment ring being designed according to one of the previously described embodiments. Advantageously, the floor and/or
or the lid is also made of plastic.

• Figure 3 a schematic sectional view of a ring section for a mounting ring of the transport container according to Figure 1 , and
• Figure 4 a schematic sectional view along line IV-IV in Figure 1 .

In Figure 1 a perspective view of a transport container 11 is shown. This transport container 11 consists of a base 12, a mounting ring 14, which comprises a plurality of side walls 15, and a lid 16 that can be placed on the mounting ring 14. On the base 12, a circumferential groove or depression 17 is preferably provided along the outer edge region, which is used for receiving and positioning of the attachment ring 14 is used. A circumferential recess is provided on an underside of the lid 16 so that the lid 16 rests securely on the attachment ring 14.

The attachment ring 14 comprises ring sections 18, 19. In the exemplary embodiment, the attachment ring 14 consists of two ring sections 18, 19. A connection point 22 is formed between the two ring sections 18, 19. The ring sections 18, 19 are each connected to one another in the connection point 22 by a holding profile 21. Alternatively, the attachment ring 14 can also be constructed from several ring sections 18, 19.

To transfer the transport container 11 for return transport, the lid 16 is first lifted off, the ring sections 18, 19 are separated from one another and folded together. These folded ring sections 18, 19 are then placed on the floor 12. The lid 16 is then positioned on top. This enables a low transport volume for return transport, as in Figure 2 is shown.

The attachment ring 14 includes the first and second ring sections 18, 19. The connection point 22 is provided, for example, in a left and right side wall 23, 24. Alternatively or additionally, a connection point 22 can also be in a rear wall 25 or a front side wall 26.

According to the exemplary embodiment, the first ring section 18 comprises the rear wall 25 and a right and left side wall section 27, 28. These side wall sections 27, 28 are preferably connected in one piece to the rear wall 25 by a hinge 29. The hinge 29 can be introduced by embossing or hot forming.

The ring section 19 comprises the front side wall 26 as well as right and left side wall sections 31, 32 arranged laterally thereon, which are preferably connected in one piece to the front side wall 26 with a hinge 29. The right side wall sections 27, 31 and the left side wall sections 28, 32 correspond in size to the side walls 23, 24 with the interposition of the holding profile 21 at the connection point 22.

The right and left side wall sections 27, 28 of the first ring section 18 are wider than the right and left side wall sections 31, 32 of the front ring section 19. The ring sections 18, 19 have a common upper end face 33 and a lower end face 34. The attachment ring 14 rests with the lower end face 34 in the recess 17 in the base 12. The cover 16 rests with its recess on the upper end face 33 of the attachment ring 14.

In Figure 3 is a schematic sectional view along the ring section 18 in an unfolded position. This ring section 18 includes the rear wall 25 and the two right and left side wall sections 27, 28 each connected to it by the hinge 29, one of the two hinges 29 not being shown. The side wall 15 and the side wall sections 23, 24 consist, for example, of two outer plastic layers 47, 48, between which a third plastic layer 49 is formed. This can be a bubble wrap or the like that has raised or recesses formed on one or both sides. These plastic layers 47, 48, 49 are welded together. The embossed sections 18 have an end edge 37 at each end. This end edge 37 extends between the upper and lower end faces 33, 34 of the ring sections 18, 19. This end edge 37 is tapered in wall thickness compared to the side wall 15 and the side wall sections 27, 28. The front edge 37 can be produced by heat forming by pressing the outer plastic layers 47, 48 together. This creates a wall section 58 that is rigid and closes the side walls 15 or side wall sections 27, 28. The wall thickness of the wall section 58 is determined by the thickness of the plastic layers 47, 48, 49 and the pressing force. Preferably, an outside of the end edge 37 is aligned flush with the outside 57 of the side wall 15 or the side wall sections 27, 28. A locking element 55 is provided on the front edge 37. This locking element 55 is designed, for example, as a recess. The locking element 55 is provided on the wall section 58 opposite the outside 57. Such a locking element 55 can take place at the same time as the front edge 37 is manufactured. The latching element 55 is adapted to the shape and/or contour of a further latching element 66 in the holding profile 21.

The side wall 15 and the right and left side wall sections 27, 28 are connected by the hinge 29. This can in turn be produced by heat forming, allowing the side wall sections 27, 28 can be pivoted or folded together to form the side wall 15.

The ring section 18 has the locking element 55 at the respective end of the right and left side wall sections 27, 28, which preferably points towards the inside after being placed on the floor 12.

The structure of the ring section 19 preferably corresponds to that of the ring section 18. The ring section 19 differs from the ring section 18 in that no locking element 55 is introduced on the end edge 37. Furthermore, the ring section 19 can differ from the ring section 18 in that the right and left side wall sections 31, 32 are narrower than the side wall sections 27, 28 of the ring section 18.

In Figure 4 is a schematic sectional view along line IV-IV in Figure 1 shown. This sectional view shows the connection point 22 with the holding profile 21 and the two ring sections 18, 19 arranged adjacent to one another. The right side wall section 27 of the ring section 18 is connected to the right side wall section 31 of the ring section 19 by the holding profile 21. This creates a closed side wall 15.

The holding profile 21 has two mutually opposite U-shaped receptacles 61, 62. These two U-shaped receptacles 61, 62 extend along a common outer leg 63. The two U-shaped receptacles 61, 62 are separated from one another by a common web 64. This web 64 forms a base for the U-shaped receptacles 61, 62, which are aligned opposite to one another. The receptacle 61 includes a locking element 66 pointing towards the inside of the receptacle 61, which is designed, for example, as a projection. This locking element 66 forms a plug/locking connection with the locking element 55 on the front edge 37. The width of the U-shaped receptacle 61 is preferably adapted to the wall thickness of the wall section of the end edge 37. An inner leg 68 of the U-shaped receptacle 61 comprises a length that preferably corresponds to the width of the wall section 58. This allows one to go outside directed end face 69 of the inner leg 68 may be set back relative to an inner wall surface of the side wall section 27 and / or the side wall 15. In addition, the end face 69 can be supported in the transition area between the end edge 37 and the non-tapered flat section 56 of the side wall 15.

The outer leg 63 is designed to be longer than the inner leg 68 in the area of the U-shaped receptacle 61.

The second U-shaped receptacle 62 is wider than the first U-shaped receptacle 61. The second U-shaped receptacle 62 preferably has twice the width of the first U-shaped receptacle 61. The inner leg 68 of the second U-shaped receptacle 62 preferably runs flush with the inside of the flat section 56 of the side wall section 31 or is set back from it. Advantageously, an end face 69 of the inner leg 68 of the second U-shaped receptacle 62 can also be supported in the transition area between the end edge 37 and the flat section 56 of the right side wall section 31. The outer leg 63 is longer than the inner leg 68 in the second U-shaped receptacle 62.

This arrangement enables a plug/locking connection to be created between the holding profile 21 and the ring section 18, so that the holding profile 21 remains on the ring section 18 during normal use. The ring section 19 can be connected to the holding profile 21 by a plug connection. To make this plug connection easier to form, the U-shaped receiving section 62 is designed to be wider than the front edge 37 of the right side wall section 31.

The above statements apply analogously to the holding profile 21, which connects a left side wall section 28 of the ring section 18 with a left side wall section 32 of the ring section 19. What is important is that a plug/locking connection is formed between the holding profile 21 and one of the ring sections 18 and only a plug connection is formed with the opposite ring section 19.

The holding profile 21 extends completely along the front edge 37 of the first and second ring sections 18, 19.

The holding profile 21 is preferably designed as an extruded/pressed profile or extrusion profile made of plastic.
