Description

The invention relates to containers made of plastic, with a rectangular bottom and four side walls, the bottom having a first stacking contour on the underside on its outer edge, the side walls having a second stacking contour at their upper edge region, and wherein when stacking containers one above the other the first stacking contour upper container and the second stack contour of a lower container in a centering engagement with each other.

From the DE 20 2014 101 556 U1 is a container according to the preamble of claim 1 for the transport and storage of goods is known, with a rectangular bottom and with four projecting, rigid or foldable side walls, the bottom underside stacking edges and the side walls each having a stacking surface, wherein the stacking edges and the stacking surfaces are designed to allow several containers to be stacked one on top of the other.

In containers for sensitive goods, such as fruit, the side walls should be as flexible as possible to avoid pressure points on the goods. On the other hand, this flexibility of the side walls leads to the problem of an increased risk of bulging of the upper edge of the side walls of lower, heavily loaded containers in a stack of loaded containers, which makes the stack unstable.

Containers with a reinforced upper edge area are also known. In the document DE 20 006 094 U1 describes a plastic container with a snap-on lid, in which at least one inward and / or at the edge of the container on the side of the container facing the top of the container for the lid and / or radially protruding reinforcing rib is formed on the outside and extends at least over a partial circumference of the container. The reinforcing rib also stabilizes the top edge of the container and thus the sealing area between the container and the lid. Since the reinforcing rib is molded onto the side wall, it is made of the same material as the rest of the side wall, so that if the side wall itself consists of a plastic which has a certain flexibility or flexibility, the reinforcing effect of the reinforcing rib is only slight.

The document DE 296 01 187 U1 shows a load carrier made of foam, in particular of particle foam, with at least one stacking edge, and deals with the problem of increasing the load-bearing capacity. To solve this problem, a stiffening profile is provided on at least part of the stack edge. Disadvantageously, foam load carriers require relatively thick walls, although only a low mechanical load-bearing capacity and a relatively small usable volume relative to the external dimensions are achieved. The use of such charge carriers is limited to applications with only low mechanical and thermal loads.

In the document DE 297 10 185 U1 describes a stackable packaging, in particular made of foamed material, which has an outer wall with an upper edge and with a support on the underside, next to which there are side stops on the inside, with packaging stacked adjacent to one another with the upper edge of the lower packaging and the underside support of the upper packaging lie on top of each other and the side stops in this stacking position are on the inside next to the top edge of the lower packaging. It is further provided that the support surface of the top edge is designed to rise at least over a partial area of its transverse extent to the inner side stop side and that the bottom support has an approximately corresponding counter-shaping. The outer edge of the outer wall can have a wall reinforcement profile, the upper side of which forms the support surface for the support of a stacked, adjacent packaging. In addition, the wall reinforcement profile can be designed as a profile that can be plugged onto the upper edge of the outer wall, preferably with an approximately U-shaped cross section. This known packaging made of foamed material also requires relatively thick walls, but here too only a low mechanical strength and a relatively small usable volume can be achieved in relation to the external dimensions. The use of such packaging is also limited to applications with only low mechanical and thermal loads.

The object of the present invention is therefore to create containers of the type mentioned at the outset which have a high level of mechanical stability and resilience, which can have side walls with a certain degree of flexibility to protect the goods in the container and which securely stack loaded containers one above the other guarantee.

A first solution to the problem is achieved according to the invention with a container of the type mentioned at the outset, which is characterized in that the upper edge region of at least two opposite side walls is reinforced by at least one form-fitting and / or non-positive reinforcement profile attached to the other side wall, and that / Each reinforcing profile has on its upper side facing away from the container at least one profile web running in the longitudinal direction of the reinforcing profile and forming a slideway for a further container to be fitted.

With the invention defined by claim 1, two or more side walls of the container are reinforced with a reinforcing profile, the material of which differs from that of the side wall. In this way, with a corresponding choice of materials for the reinforcement profiles, a particularly large reinforcement effect can be achieved. The side walls of the container, which are particularly stressed when containers are stacked one above the other, can thus be stabilized with relatively little technical effort so that bulging of the upper edge of loaded containers in the container stack can be ruled out with the usual stack heights and loads. At the same time, the side walls themselves can advantageously have a certain flexibility which is gentle on the goods in the container. In order to facilitate manual stacking of the containers on top of one another, the / each reinforcement profile has on its upper side facing away from the container at least one profile web which runs in the longitudinal direction of the reinforcement profile and forms a slideway for a further container to be put on. It is therefore sufficient to initially place an upper container on a lower container with only a partial overlap, and then to place the upper container to move along the slideway of the lower container to its final stacking position.

As mentioned above, the reinforcement profile is attached to the rest of the side wall in a positive and / or non-positive manner. For the specific design of this connection, it is provided in a first embodiment that the / each reinforcement profile in a lower region facing the side wall has a groove which is open towards the bottom or a web pointing downwards, and that at the upper edge of the other side wall there is a web or an upwardly open groove is formed and that the reinforcement profile is latched or clamped or pushed onto the web of the side wall with its groove or is engaged or clamped or pushed into the groove of the side wall with its web. The reinforcement profile is thus connected to the associated side wall from above when the container is manufactured.

In order that the cohesion of the side wall and the reinforcement profile is reliably maintained even when the container is used roughly, it is proposed that locking elements interacting on the side wall and on the associated reinforcement profile are formed. These locking elements come into engagement with one another when the reinforcement profile is attached to the rest of the side wall, so that an automatic detachment of the reinforcement profile from the side wall is excluded, but any desired non-destructive removal or replacement of the reinforcement profile remains possible.

Furthermore, it is preferably provided for the container that the upper edge region of two mutually opposite, longer side walls is reinforced by a reinforcing profile that extends over the length of the associated side wall. This effectively counteracts the naturally greater risk of bulging in the longer side walls.

It is also preferably provided that the side walls themselves consist of an unreinforced thermoplastic and that the / each reinforcement profile consists of a fiber-reinforced plastic or of metal. The side walls per se or the container itself can therefore be made from a relatively inexpensive material, in particular as injection molded parts. The reinforcement profiles can be made from a more stable material. The fiber-reinforced plastic is preferably reinforced with glass, carbon or natural fibers, from which the reinforcement profile can also advantageously be produced by injection molding.

For the previously described containers with slideways, a further embodiment provides that sections of the stacking contour of the base below the side walls having the slideways are each designed with a groove, that the slideways and grooves are each designed such that when an upper container is placed on it on a lower container in a position offset relative to one another in the longitudinal direction of the slideways and grooves, the upper container slidably stands in an elevated position on the slideways of the lower container and that when or after the upper container is moved into a position congruent with the lower container Enter the slides in a stack end position while lowering the upper container. The container in this configuration offers several advantages. First of all, it enables an upper container to be placed on a lower container with an offset of the containers relative to one another and a subsequent displacement of the upper container on the lower container into the congruent stacking position, which in particular means manual stacking of the containers, especially in their loaded state Handling personnel relieved. When the upper container is pushed onto the container below it, the upper container first slides in an elevated position on the slideways of the lower container and only lowers into its end-of-stack position at the end of the displacement process. As a result, a larger or larger space between the two is advantageous when pushed on Containers, specifically between the goods to be transported, such as fruit, in the lower container on one side and the underside of the bottom of the upper container on the other side. In this way, sensitive goods in the lower container, in particular fruit, which protrude slightly above the container edge, are not damaged by rubbing or scratching.

For a smooth transition of an upper container from an initially shifted, elevated position into its lowered stacking end position, the invention provides that each slideway is stepped or beveled or rounded at its end regions.

Slideways on two long side walls are useful for the practical use of the containers. Alternatively, slideways can be provided on two short side walls.

In order to enable safe mixed stacking of the containers according to the invention with conventional containers of the same base area dimensions, it is provided that the two side walls not having the slideways each have one or more spaced apart from one another in the longitudinal direction of these side walls, a conventional container placed on a container according to the invention, against shifting into Have cusps securing the longitudinal direction of the slideways, the height of which corresponds to the height of the slideways.

In the following description of the figures, the same parts in the various drawing figures are always provided with the same reference numerals, so that all reference numerals do not have to be explained again for each drawing figure.

The Figure 1 the drawing shows a container 1 with a bottom 2, with two mutually opposite first, longer side walls 3 and with two opposing second, shorter side walls 4, viewed obliquely from above. The container 1 is designed here as a folding container, in which the side walls 3, 4 are articulated to the bottom 2, so that they are between the in Figure 1 shown, upright use position and a rest position in which the four side walls 3, 4 are folded inwards on the floor 2, is adjustable.

Furthermore, the side walls 3, 4 are each provided in a manner known per se with a handle opening 31, 41 and with releasable locking means 43 for mutually locking the side walls 3, 4 in their use position.

By means of a lower stacking contour 20 on the outer edge region of the base 2 and an upper stacking contour 30, 40 each on the upper edge of the side walls 3, 4, several containers 1 can be stacked one above the other in a centering manner.

The bottom 2 and the side walls 3, 4 here are injection molded parts made of a thermoplastic material, at least the side walls 3 having flexible wall areas 33 with a certain flexibility in order to protect goods stored or transported in the container 1.

In order to be able to safely and reliably stack such containers 1 on top of one another without bulging the upper edge of the side walls 3, particularly in the case of lower containers 1 in a stack of containers from loaded containers 1, there is a reinforcement profile 5 at each two opposite, longer side walls 3 positively attached, locked here. The reinforcement profiles 5 consist of a material, in particular of fiber-reinforced plastic or of metal, which is more stable than the material from which the side walls 3 are made, usually an unreinforced plastic. The reinforcement profiles 5 thus ensure that the side walls 3 have a particularly high stability in their upper edge region, as a result of which undesired bulging of the upper edge of the side walls 3 in a stack of containers is avoided.

Each reinforcing profile 5 has an upward-facing profile web 50 which extends in the longitudinal direction of the reinforcing profile 5 and the associated side wall 3. The profile webs 50 form on their upper side a slideway 11 on which an upper container 1 on a lower container 1 after only partially overlaying can be easily moved into its final stacking position.

The end regions 12 of the slideway 11 are chamfered in order to shift the upper container 1 in a position elevated relative to the lower container 1 and to lower the upper container 1 relative to the lower container 1 only immediately before or when the congruent position of the upper container 1 is reached. As a result, the goods in the lower container 1 are protected from damage by pushing on the upper container 1.

So that conventional containers with the same base dimensions can be safely stacked on the container, two protruding bumps 44 are formed on the upper edge of the shorter side walls 4 formed by the upper stack contour 40 at a distance from one another. These humps 44 block a conventional container placed on the container 1 against unwanted displacement along the slideways 11 beyond a congruent stacking position relative to the container 1 arranged below.

Figure 2 shows the container 1 Figure 1 in frontal view of one of the longer side walls 3 with the reinforcing profile 5 attached to it Figure 2 the bottom 2 with its stacking contour 20 is visible. At the upper edge of the side wall 3, the reinforcement profile 5 is connected to the side wall 3. Beneath a central section of the reinforcing profile 5 is the handle opening 31 in the side wall 3. A central surface area of the side wall 3 bordered by the four edge areas of the side wall 3 forms the flexible wall area 33, which has a certain flexibility. On the upper side of the reinforcing profile 5, its profile web 50 is visible, which forms the stacking contour 30 of the side wall 3 and one of the slideways 11 with the beveled slideway end regions 12.

Figure 3 shows one of the longer side walls 3 and a reinforcing profile 5 not yet attached, in a view obliquely from above. The side wall 3 has on its upper edge an upwardly pointing web 35, on which locking elements 34 in the form of locking lugs protruding from the surface of the web are formed at regular intervals. The reinforcement profile 5 shown above the side wall 3, not yet connected to it, has on its underside a groove 53 with which the reinforcement profile 5 can be positively fitted onto the web 35 from top to bottom in the vertical direction. By means of locking elements 54 in the form of locking openings arranged in the reinforcing profile 5, the locking profile 5 is locked in a reliable manner, but can be detached if necessary, with the locking elements 34 on the side wall 3, thereby achieving the desired reinforcement and stiffening of the upper edge area of the side wall 3.

On the lower edge of the side wall 3 are in Figure 3 Several, here four, hinges 32 are visible, with which the side wall 3 can be connected in an articulated manner to the bottom 2 of the container 1, not shown here.

Figure 4 shows a part of the longer side wall 3 and the reinforcement profile 5 now associated therewith Figure 3 in an enlarged detail view. Bottom left in Figure 4 part of the side wall 3 with the handle opening 31 is visible. The reinforcement profile 5 runs over it.

One of the pairs of locking elements 34, 54 is visible to the right above the grip opening 31, the locking element 34 of the side wall 3 having the shape of a locking lug, which engages in the locking element 54 of the reinforcing profile 5 which is designed as a locking opening.

Furthermore clarifies the Figure 4 that the reinforcing profile 5 has, on its side facing the inside of the container, a plurality of parallel lateral profile wings 51 which make the reinforcing profile 5 particularly rigid with relatively little use of material.

At the top of the reinforcing profile 5 runs its vertical profile web 50, the top of which forms the slideway 11 of the side wall 3.

Figure 5 shows part of the longer side wall 3 and the associated reinforcement profile 5 in an enlarged view, partly in view and partly in a first vertical section. On the right in Figure 5 lying cut surface can be seen how the reinforcing profile 5 with its groove 53 is positively placed on the web 35 on the upper edge of the side wall 3.

Furthermore shows the Figure 5 that the reinforcing profile 5 also has lateral profile wings 51 running parallel to one another in the longitudinal direction of the reinforcing profile 5 on its surface facing away from the viewer and pointing towards the interior of the container for effective stiffening.

Figure 6 shows part of the longer side wall 3 and the associated reinforcing profile 5 in an enlarged view, partly in view and partly in a second vertical section. The section here runs through one of the pairs of locking elements 34, 54, so that their interaction can be seen particularly clearly here.

Figure 7 shows a container 1, each with a reinforcement profile 5 on two opposite, longer side walls 3, in view of a shorter side wall 4. Left and right in Figure 7 is therefore one of the two longer side walls 3 below Figure 7 the bottom 2 lies with its underside stacking contour 20.

On the upper side, the container 1 on the shorter side wall 4 facing the viewer has the stacking contour 40 forming its upper edge. At a distance from the top edge A handle opening 41 is offset in the transverse center of the side wall 4. Above the handle opening 41, two resilient locking means 43, which can be displaced in the horizontal direction, run parallel to the surface of the side wall 42. At the upper edge of the side wall 4 there are two upwardly protruding bumps 44 molded, which serve to secure a conventional container of the same base dimensions placed on the container 1 in its congruent stacking position relative to the container 1 and to prevent the upper, conventional container from being moved along the slideways 11 from the congruent stacking position.

Left and right in Figure 7 the associated stacking contours 30 are visible along the upper edge of the two side walls 3. The stack contours 30 are each formed here by one of the reinforcement profiles 5 which are snapped onto the rest of the side wall 3 at the top and each have a longitudinally extending profile web 50 on the upper side, the top side of which each forms a slideway 11.

The bottom 2 points to its in Figure 7 on the left and right perpendicular to the plane of the longitudinal sides downwardly open grooves 21 which are arranged congruent to the profile webs 50. If an identical further container 1 is initially placed on the container 1 with an offset in the longitudinal direction of the slideways 11, the upper container 1 can be moved by means of its grooves 21 on the slideways 11 of the lower container 1 in an elevated position during the shifting to one with the lower container 1 congruent stack end position are moved, in which the upper container 1 relative to the lower container 1 then sinks into its final stacking position by cooperation of the appropriately designed slideways 11 and grooves 21.

Figure 8 shows a further container 1, each with a reinforcement profile 5 on two opposite, longer side walls 3, in an oblique view from above. In contrast to the container according to Figure 1 here are the reinforcement profiles 5 as insert parts, which are inserted as prefabricated parts in the manufacture of the container 1 or its side walls 3 in an injection mold, in which the remaining side wall is then injected, whereby the reinforcement profiles 5 are securely connected to the respective other side wall 3 become.

The slideways 11 on the top of the stack contours 30 of the longer side walls 3 are not part of the reinforcement profiles 5 here, but part of the other side walls 3 and in each case formed on the top of a web 35 integral with the side wall 3.

With regard to the other in Figure 8 illustrated parts and details of the container 1 is made to the preceding description.

Figure 9 shows one of the longer side walls 3 of the container Figure 8 and separately an associated reinforcement profile 5, in a view obliquely from above. As the Figure 9 clarifies, here the reinforcing profile 5 has two longitudinal webs 55 running parallel to one another and in the longitudinal direction of the reinforcing profile 5, as well as several transverse webs 56 connecting them to one another and spaced apart in the longitudinal direction. In the finished state of the side wall 3, the plastic material of the other side wall 3 surrounds the transverse webs 56 of the reinforcing profile 5, whereby this is securely connected to the rest of the side wall 3.

Next is the Figure 9 clearly visible that here the slideway 11 is formed on the top of the web 35 of the stacking contour 30 of the side wall 3, that is to say it is not part of the reinforcing profile 5 here.

Figure 10 shows the side wall Figure 9 with the associated reinforcement profile 5, again in an oblique view from above. It can be seen here in particular that the reinforcement profile 5 runs below the slideway 11 and, with its upper side, forms part of the stacking contour 30 together with the upper edge of the side wall 3.

Figure 11 shows one of the longer side walls 3 of another container 1 and a reinforcement profile 5 not yet connected to it, in a view obliquely from above. In this exemplary embodiment, the reinforcement profile 5 can be latched to the rest of the side wall by being plugged in from top to bottom, for which purpose the side wall 3 has latching elements 34 and the reinforcement profile 5 has latching elements 54 cooperating therewith.

At its front end, the reinforcement profile 5 here has a downward-facing guide pin 57, each of which is close to the corresponding receptacle Side edges of the side wall 3 are receivable. The guide pins 57 in particular prevent the reinforcement profile 5 from tilting, which here again has an upwardly pointing profile web 50 with the top-side slide track 11, on which the weight of the respective upper container when stacking containers 1 is loaded when it is moved into the congruent stacking position.

Figure 12 shows the side wall 3 Figure 11 with associated reinforcement profile 5, also in an oblique view from above. The locking elements 34 of the side wall 3 and the locking elements 54 of the reinforcement profile 5 are now in locking engagement with one another and secure the reinforcement profile 5 in its assembly position on the side wall 3. The reinforcement profile 5 projects upwards from its longitudinally extending profile web 50, the upper side of which is the slideway 11 forms with their bevelled end regions 12.

Figure 13 finally shows one of the longer side walls 3 of a further container 1 and a reinforcing profile 5 connected to it, in a view obliquely from above. It is characteristic of the exemplary embodiment shown here that the reinforcement profile 5 is welded to the remaining side wall 3 or that the side wall 3 including the reinforcement profile 5 is produced as a two-component injection molded part. In both versions, which do not differ in their appearance from the outside, the reinforcement profile 5 is particularly firmly and permanently securely connected to the remaining side wall 3.

Here, the slideway 11 is formed on the upper side of a web 35 of the stack contour 30 of the side wall 3, that is to say not part of the reinforcing profile 5 in this exemplary embodiment. <u> List of reference symbols: </u> character designation 1 container 11 Slideway 12th End ranges from 11 2nd Floor of 1 20 Stack contour on 2 21 Grooves in 20 3rd first, longer side walls 30th Stack contour on 3 31 Handle opening in 3 32 Hinges on 3 33 flexible wall area of 3 34 Locking elements on 3 35 Footbridge at the top of 3 4th second, shorter side walls 40 Stack contour / upper edge on 4 41 Handle opening in 4 43 Locking means 44 Hump at 4 5 Reinforcement profiles 50 Profile web on top of 5 51 Profile wing on the side of 5 53 Groove down in 5 for 35 54 Snap elements on 5 55 Longitudinal webs 56 Crossbars 57 Guide pin
