Definitions
- the invention relates to a transport container according to the preamble of claim 1.
- Such transport devices are known, for example, from DE 199 31 269 A1 or EP 2 824 035 B1 and are used, for example, for transporting parts supplied by the automobile industry. They have a base body made of foamed plastic that is soft, so that parts accommodated in the transport container are protected from damage.
- transport containers are stacked one on top of the other for transport, so that high forces can act on the lower transport containers of a stack, particularly when the transport containers are fully loaded.
- Transport containers with a base made of foamed plastic are therefore often provided with reinforcement elements which, when transport containers are stacked on top of one another, absorb at least part of the weight of the upper container and prevent deformation of the foam base.
- the reinforcing elements are designed in multiple parts in order to be able to insert them into the base body in a simple manner. However, this is often found to be complicated during assembly.
- the invention is based on the idea of simply inserting the reinforcement element into the base body, with the upper or lower bearing surface preventing it from slipping through the base body by being expediently designed to be larger than the cross section of a receiving opening in the base body that accommodates the respective reinforcement element.
- the partial areas are arranged in a common plane.
- the upper bearing surface of each reinforcement element is then expediently at least as large as the lower bearing surface.
- it is preferably designed as a continuous surface. It is preferred that a projection of the upper bearing surface onto the lower bearing surface, ie a virtual displacement of the upper bearing surface along the common surface normal in the direction of the lower bearing surface, completely covers the lower bearing surface. If several transport containers according to the invention are stacked one on top of the other, with the reinforcement elements being arranged one above the other in at least one row, this feature ensures that the lower support surface can rest completely on the upper support surface of the reinforcement element of the next lower transport container.
- the at least one reinforcement element according to the first exemplary embodiment has an upper part delimited at the top by the upper bearing surface and lower parts protruding downwards from the upper part and delimited at the bottom by one of the partial surfaces.
- the upper part can have a support plate having the upper support surface and an intermediate piece carrying the lower parts, the support plate having a circumferential edge protruding laterally beyond the intermediate piece. The edge also prevents the reinforcement element from slipping through when it is inserted into the base body.
- two lower parts see through a connecting part of the base body and form a connecting web which also prevents the reinforcing element from slipping through the base body.
- the at least one reinforcement element expediently has a height measured between the upper bearing surface and the lower bearing surface which deviates by at most 10%, preferably by at most 5%, from a height of the base body measured between an upper and a lower installation surface.
- the upper installation surface is intended for erecting a lower installation surface of an identical transport container
- the lower installation surface is intended for installation on an upper installation surface of an identical transport container.
- the height of the reinforcement element it is possible for the height of the reinforcement element to be greater than the height of the base body, so that when several transport containers according to the invention are stacked on top of one another, only the reinforcement elements rest on one another.
- the height of the base body is also possible for the height of the base body to be greater than the height of the at least one reinforcement element, so that when several transport containers according to the invention are stacked one on top of the other, the reinforcement elements only rest on one another if the base bodies are compressed a little by the weight of the transport containers lying on top of one another will.
- the sub-areas are arranged in different planes. They are expediently connected to one another by a transverse surface.
- the upper bearing surface has at least two surface parts arranged at a distance from one another. These are expediently arranged in different planes, the distance between the planes corresponding to the distance between the planes in which the sub-areas are arranged.
- each surface part is preferably assigned a partial surface whose projection onto the surface part completely covers the surface part.
- the second exemplary embodiment represents the reversal of the first exemplary embodiment, in that the at least one reinforcement element is inserted from below into a receiving opening in the base body and the lower support surface protrudes beyond the edge of the receiving opening, so that the reinforcement element cannot slip through the base body.
- the at least one reinforcement element is expediently made in one piece and preferably made of polypropylene (PP).
- PP polypropylene
- An injection molding process is advantageously used here. Since only the upper part has a peripheral edge, but not the lower parts, the reinforcing element can be produced in different sizes with the same injection mold. For this purpose, the height of the injection mold only has to be varied.
- the base body has an essentially rectangular outline and that a reinforcing element is arranged in each of the corners.
- the reinforcement elements can absorb the weight well when stacked.
- the configuration according to the second exemplary embodiment is particularly advantageous if the transport containers are to accommodate heavy objects, since their weight cannot then move the base bodies downwards with respect to the reinforcement elements, so that the reinforcement elements are pushed out of the base bodies.
- FIG. 1 shows a transport container according to a first exemplary embodiment in a perspective view obliquely from above;
- FIG. 2 shows the transport container according to FIG. 1 in an exploded view
- FIG. 3 shows a section through the transport container according to FIG. 1 in the area of a corner; 4a, b, c shows a reinforcing element according to the first exemplary embodiment in various perspective illustrations from different viewing directions;
- FIG. 5 shows a transport container according to a second embodiment in a perspective view obliquely from below in an exploded view
- FIG. 6 shows a section through the transport container according to FIG. 5 in the area of a corner
- FIG. 7a, b, c shows a reinforcing element according to the second exemplary embodiment in various perspective illustrations from different viewing directions.
- the transport container 10 has a base body 12 which is produced in one piece from a foamed plastic, in the present exemplary embodiment from expanded polypropylene (EPP).
- the base body 12 has an approximately rectangular outline with rounded corners 32 and has a bottom 14 and side walls 16 that stand up from the bottom 14 and surround a receiving space 18 that is open at the top.
- the side walls 16 are delimited at the top by a peripheral stacking edge 20 which has recesses 22 which are open at the top and towards the receiving space 18 .
- the edge of the stack 20 is bounded at the top by an upper mounting surface 28 , while the underside of the paragraph 24 forms a lower mounting surface 30 .
- Several transport containers 10 of the same construction can be stacked on top of one another by the lower support surface 30 of the respective upper transport container 10 resting on the upper support surface 28 of the respective lower transport container 10 and the teeth of the respective upper transport container 10 engaging in the recesses 22 of the respective lower transport container 10.
- the base body 12 has a receiving opening 34 passing through it from top to bottom. All receiving openings 34 are identical in design, and a reinforcing element 36 is received in each receiving opening 34, which is produced in one piece from polypropylene (PP) as an injection molded part.
- PP polypropylene
- Each reinforcement element 36 has an upper part 38 with an intermediate piece 40 and a support plate 42 covering the intermediate piece 40 and delimited at the top by an upper support surface 44 .
- the support plate 42 has a peripheral edge 46 which protrudes beyond the intermediate piece 40 .
- Each of the reinforcing elements 36 also has two lower parts 48 protruding downwards from the intermediate piece 40, which are each delimited at the bottom by a partial surface 50, the partial surfaces 50 of each reinforcing element being arranged at a distance from one another in a common plane and a lower bearing surface 52 form. Between the two lower parts 48 there extends through a connecting part 54 of the base body 12 which divides the receiving opening 34 in the middle and on which the intermediate piece rests in the area between the lower parts 48 .
- the upper and lower bearing surfaces 44, 52 are each exposed, with the bearing plate 42 protruding from the base body 12 and the peripheral edge 46 rests on the base body 12.
- the fact that the upper and lower bearing surfaces 44, 52 are exposed means that they are freely accessible from above and below, respectively.
- the height of the reinforcing elements 36 measured between the upper bearing surface 44 and the lower bearing surface 52 running parallel to it within the scope of manufacturing tolerances is approximately 3% less than the height of the base body 12 measured between the upper and lower installation surfaces 28, 30, with the upper and lower mounting surface 28, 30 in turn run parallel to one another within the scope of manufacturing tolerances.
- the reinforcing elements 36 form four rows with reinforcing elements 36 arranged one above the other rest on the upper bearing surface 44 of the next lower reinforcing element in the row.
- the upper bearing surface 44 of each reinforcement element 36 is larger than the lower bearing surface 52 and a projection of the upper bearing surface 44 covers the lower bearing surface 52 completely.
- the transport container 10' according to the second exemplary embodiment differs from the transport container 10 according to the first exemplary embodiment essentially in the shape of the reinforcing elements 36. However, their mode of action and purpose have remained unchanged compared to the first exemplary embodiment. Features that are the same or have the same effect are therefore provided with the same reference symbols in the following.
- the transport container 10' according to the second exemplary embodiment also has a base body 12 which is produced in one piece from a foamed plastic such as EPP.
- the design of the base body 12 with a base 14, side walls 16, a peripheral stacking edge 20, recesses 22, a shoulder 24, an upper and lower installation surface 28, 30 and rounded corners 32 corresponds to the base body 12 according to the first exemplary embodiment.
- the teeth 26 not shown in FIGS. 1, 2 are shown in the view from below according to FIG.
- the base body 12 according to the second exemplary embodiment also has a receiving opening 34 passing through it from top to bottom at each of the corners 32, with all receiving openings 34 being of identical design and receiving a reinforcing element 36 which is produced in one piece as an injection molded part from polypropylene.
- the lower bearing surface 50 of the reinforcing element 36 in the second exemplary embodiment is larger than the upper bearing surface 44.
- the sub-surfaces 50 of the lower bearing surface 52 are arranged in two spaced, parallel planes and connected to each other by a transverse surface 54 .
- the lower bearing surface 52 is also larger than the cross section of the associated receiving opening 34, so that the reinforcing elements 36 have to be pushed into the receiving openings 34 from below.
- the upper bearing surface 44 has two surface parts 56 which are also arranged in different planes and run parallel to the partial surfaces 50 .
- the surface portions 56 are arranged parallel to one another at the same distance as the sub-surfaces 50 of the lower support surface 52.
- Each of the surface portions 56 is assigned a sub-surface 50 whose projection onto the surface portion 56 completely covers it.
- One of the surface parts 56 is designed as a continuous surface, while the other has several partial surface parts 58, three in the present exemplary embodiment.
- the transport container according to the second exemplary embodiment is particularly suitable for accommodating heavy objects.
- the enlarged lower support surface 52 prevents the lowering of a base body 12 accommodating heavy objects relative to the reinforcement elements 36 accommodated in it, which in turn rest on the reinforcement elements 36 of the next lower transport container 10'.
- the lower installation surface 30 of the base body 12 of a transport container 10' does not lie on the upper installation surface when stacked on a transport container 10' of the same construction, but on the upper installation surface 28 the reinforcing elements 36 lie with their lower contact surfaces 52.
- the invention relates to a transport container 10 with a base body 12 made of foamed plastic, preferably expanded polypropylene (EPP), and with at least one reinforcement element 36 accommodated in the base body 12, which has an upper support surface 44 on its upper side and one of the upper Bearing surface 44 facing away from and parallel to this lower bearing surface 52 on its underside, wherein the upper bearing surface 44 and the lower bearing surface 52 are exposed
- the lower bearing surface 52 has at least two partial surfaces 50 arranged at a distance from one another.
