Description

The invention relates to a Aufsetzring for a transport container, a transport container with at least one Aufsetzring and a method for producing such a Aufsetzringes.

From the DE 295 03 254 U1 a transport container is known, which is formed from a bottom, which is preferably designed as a transport pallet, a Aufsetzring and an attachable on the Aufsetzring cover. The Aufsetzring is formed of a plurality of side walls, wherein the side walls are provided foldable to each other, so that the Aufsetzring is collapsible. The folded Aufsetzring is thereby placed on the ground and covered by the lid, so that this transport container can be transported folded back with a reduced transport volume.

The object of the invention is to propose a Aufsetzring for a transport container, in which a simple handling is given. The object of the invention is further to propose a transport container with such a Aufsetzring, which withstands easy handling and high loads during use. The object of the invention is also to propose a method for producing such a Aufsetzringes.

The object is achieved by a support ring for a transport container, which consists of a transport pallet, at least one Aufsetzring positionable thereon and a container lid, with a plurality of side walls whose length is bounded by two spaced side edges and the opposite side edges of two adjacent side walls are interconnected, and the height of the side walls is limited by a first end face and a second end face, wherein a first profile section is formed on the first end side and a second profile section is formed on the second end side, which profile is complementary to the first profile section and in that by the intermeshing profile sections Moving movement, transverse to the longitudinal extent of the side walls, is locked. As a result, a Aufsetzring for a transport container is formed, which can be positioned in a defined position on the transport pallet or on another Aufsetzring. In this case, the positioning of the Aufsetzringes to the transport pallet or to the other Aufsetzring done by the second profile section engages a Aufsetzring, in the first profile section of the other Aufsetzringes or the transport pallet. By this meshing of the profile sections, a relative movement of the two Aufsetzringe each other or a relative movement of the Aufsetzringes be prevented for transport pallet. In addition, several Aufsetzringe are stacked on top of each other by the first profile section and the second profile section, so that a transport volume of the transport container in response to the number stacked Aufsetzringe is adaptable.

An embodiment of the Aufsetzrings provides that when stacking the Aufsetzringe the first profile section of the lower Aufsetzrings engages in the second profile section of the Aufsetzrings mounted thereon. By this engagement of the two profile sections when stacking the Aufsetzringe a non-slip position of the Aufsetzringe can be formed to each other. As a result, the stacked Aufsetzringe can not be shifted from each other even under load in use. A safe load transfer when stacked transport containers is possible.

A further embodiment of the Aufsetzrings provides that the Aufsetzring engages with the second profile section on the first profile section of the transport pallet. As a result, a non-slip position of the patch on the transport pallet Aufsetzrings be formed.

An embodiment of the Aufsetzringes provides that the first profile section is formed by an at least partially along the first end face extending web, which is preferably arranged offset in a longitudinal center plane of the side wall or laterally. As a result, a first profile section is formed, which extends in the form of a continuous web along the first end face. By such a continuous web a particularly resilient connection between the first profile section and the second profile section may be formed, since a transverse load over the entire length of the web can be accommodated. Likewise, the first profile section may be formed as an interrupted web.

A preferred development of the Aufsetzringes provides that the second profile section is formed by a plurality of molded projections, which are arranged opposite to each other along the second end side, so that between the projections at least one extending along the second end side holding portion is formed, which is for receiving the first Profile section is formed. The holding section may extend over the length of the second end face into which the first profile section formed as a web can engage. The opposing portions of the projections form a quasi-continuous holding portion, although this is interrupted several times. The resulting lateral boundary for the first profile section prevents one relative displacement movement of the side walls transversely to the longitudinal extent of the second end face.

An advantageous embodiment of the Aufsetzringes provides that the integrally formed on the second end side projections are arranged off-center to the longitudinal center plane of the side wall, in particular flush with the outer wall portions of the side walls. Due to the eccentric arrangement of the projections to the longitudinal center plane of the side wall can be achieved that a wider holding portion for the first profile section can be formed. This allows a wider configuration of the first profile section, so that it can have a higher dimensional stability.

A further advantageous embodiment of the Aufsetzringes provides that the projections are mutually and preferably arranged offset to each other along the second end face. As a result, mutually projections are provided at a distance from each other, which form the lateral boundary of the holding portion. Thereby, a plurality of projections along the second end face can be provided, each forming a single limiting component of the holding portion. By picking up a load by a first profile section inserted into the holding section from a multiplicity of projections spaced apart from one another, an optimal introduction of force into the side wall can be made possible.

An embodiment of the Aufsetzringes provides that the mutually arranged to the longitudinal central plane projections are provided in mirror image to each other, wherein an end portion of the one projection is associated with an end portion of the opposite projection, so that intermediate bearing surfaces are provided which form part of the holding portion. By these offset and mirror-inverted projections arranged, the holding portion between the mutually facing end portions of the projections can be formed.

A development of Aufsetzringes provides that each projection has at least one facing the center of the end face contact surface, so that the opposing contact surfaces of the projections form a groove-shaped holding portion. As a result, a plurality of contact surfaces is formed, which form a lateral boundary to the extension direction of the holding section along the second end face. Thus, a connection between the first and second profile section is formed, which can withstand particularly high loads.

An advantageous embodiment of the Aufsetzringes provides that the projections of the second profile section in a plan view have a substantially C-shaped, U-shaped, V-shaped or trough-shaped profile cross-section, and preferably the profile openings of the substantially C-shaped, U-shaped , V-shaped or trough-shaped projections are aligned to the longitudinal center plane. Thereby, the abutment surfaces of the projections point to the longitudinal median plane of the side wall and form the holding section. Such profile cross-sections allow particularly torsion-resistant and resilient projections, so that they can be absorbed by this particularly high forces.

An advantageous development of the Aufsetzringes provides that the side wall is formed by a heat transformation of at least two plastic films into a multilayer plate, in particular to a two-layered hollow chamber plate. By such a configuration of the side wall, a particularly low weight of the side walls can be achieved. Thus, a Aufsetzring can be formed, in which an optimal relationship between dead weight and transport volume is given.

It is particularly preferably provided that the projections of the second profile section of the Aufsetzringes are formed by the heat deformation of the at least two plastic films and preferably form the end faces of the at least two plastic films a footprint of the projections. Thereby, the projections can be formed in only one forming step at the same time for forming the side wall. In addition, the projections and the side wall can be configured as a coherent component, so that a higher dimensional stability of the projections can be achieved. Due to the footprint on the projections an approximately vertical force is possible when placing the projections on a further Aufsetzring or on the bottom of the transport pallet. This increases the stability of the transport container.

Furthermore, it is preferably provided that the web of the first profile section is formed by the heat deformation of the at least two plastic films and preferably the end faces of the at least two plastic films form a footprint of the web. This also makes it possible to provide that the web is formed in only one forming step at the same time as the shaping of the side wall.

An embodiment of the Aufsetzringes provides that at least a guide plate is formed on the second end side of the side wall, which is provided on an outer side of the side wall and opposite the projections of the second profile section has a greater height. Such a guide plate can be a placement of the To facilitate Aufsetzringes on the ground or another Aufsetzring. Here, this forms a lateral guide during placement by the guide plate first rests against an outer side of the transport pallet or the other Aufsetzringes before the profile sections interlock. In addition, the at least one guide plate form a lateral boundary for the Aufsetzring, so that slipping of the Aufsetzringes on the ground or slipping of two Aufsetzringe each other is prevented.

It is particularly preferred that the Aufsetzring between the opposite side edges of the side walls has a hinge connection, in particular a film hinge, so that the Aufsetzring is collapsible and in particular that two opposite side walls of the Aufsetzringes are each formed of two side wall sections with a fold connection provided therebetween, so that the Aufsetzring is foldable in an M-fold. As a result, an expandable and collapsible Aufsetzring is formed. This can be unfolded for the transport of goods in a position of use and folded together for a return transport of the Aufsetzringes in a transport position. In this transport position, the Aufsetzring occupies a small volume of space, so that an economic return transport is possible.

An advantageous development of the Aufsetzringes provides that in a corner region between two adjacent side walls at least one corner element is provided through which a load transfer occurs when stacking Aufsetzringen. The corner elements of two stacked Aufsetzringe with the end faces of the corner elements lie on each other, so that a support of an upper corner element is made possible on an underlying corner element. By this additional support, a larger power transmission can be achieved with a load of stacked Aufsetzringen.

The object is further achieved by a transport container, in particular pallet container, with a bottom, with a lid and with at least one Aufsetzring arranged therebetween, wherein the Aufsetzring is formed according to one of the embodiments described above. As a result, a transport container is formed, which can be composed of one or more Aufsetzringen. This allows a variable adaptation to a transport volume of the transport container. By folding the at least one Aufsetzringes consequently a space-saving and thus cost-return transport can be possible.

An advantageous embodiment of the transport container provides that the provided on the second end face of the Aufsetzringes second profile section for positive connection to the ground on a provided on an upper side of the bottom first, at least partially extending profile section is placed. As a result, the Aufsetzring can be mounted slip-proof on the ground by the provided on the ground first profile section engages the second profile section on Aufsetzring.

Advantageously, the bottom of the transport container as a pallet, in particular as a multi-layered hollow chamber pallet is formed. This allows easy handling of the transport container can be achieved by this can be transported with a conventional forklift.

The object is also provided by a method for producing a Aufsetzringes consisting of several side walls, in particular for a transport container, in which a first preferably heated plastic film between an upper tool and a lower tool of a mold is introduced, wherein the first plastic film by applying a vacuum on the lower tool is brought to rest on the lower tool to form a first mold part, wherein the lower tool has in a first edge region a first shape profile, through which a part of a first profile section is formed by a shoulder extending along the first edge region and the lower tool is formed in one of the first Edge region opposite the second edge region has a second shape profile, through which a part of a second profile section is formed by a plurality of juxtaposed and spaced recesses, in which a second preferably e rwärmte plastic film is introduced between the upper tool and the lower tool, wherein the second plastic film is brought by applying a vacuum on the upper tool to rest on the upper tool to form a second molded part, wherein the upper tool in a third edge region has a third shape profile, through which a corresponding part of the first profile section is formed and the upper tool in a fourth edge region has a fourth shape profile, through which a corresponding part of the second profile section is formed, wherein the upper tool and the lower tool closed and the first and second molded part at least in the region of the molded sections the Unterwerkzeugs and upper tool are pressed and welded and after opening the upper tool and lower tool, the at least one side wall with the first and complementary to the first profile section formed second Profile section is removed from the mold. By such a method, a manufacturing process for a Aufsetzring is achieved, in which the side walls for the Aufsetzring of two plastic films are formed into hollow chamber plates and at the same time on a first and second end side of the side walls of the first and second profile section is formed. In this way, the side walls with the first and second profile sections formed thereon can be formed by a minimum of method steps. As a result, a very fast and material-saving production process is achieved, so that a large number of Aufsetzringen are highly efficient and inexpensive to produce.

A preferred embodiment of the method provides that after removing the at least one side wall from the mold a holding portion, in particular a groove is introduced in a longitudinal center plane along an end side of the side wall or laterally offset from the longitudinal center plane of the side wall in the second profile section. As a result, a second profile section is formed with a groove-shaped holding section, in which the first profile section can be inserted, so that the first and second profile section can engage in one another. This groove-shaped holding portion can be introduced, for example, with a hand or Tischfräsgerät in the second profile section, in particular milled.
