Definitions

  • the invention relates to a container arrangement with a plurality of plastic containers which can be stacked one above the other and which have a container base and at least three, preferably four, projecting beyond the container base and connected to one another at container corners and forming a common circumferential container top edge.
  • stacking containers In the material flow of industrial companies, workpieces are often delivered in containers, temporarily stored and brought to the respective work place. For transport and storage purposes, these containers must be stackable to form container arrangements and must therefore be provided with stacking edges in the area of their lower and upper edges.
  • the known stacking edges are designed to run all around, the upper edge of the container simultaneously forming a supporting edge for the stacking container located above it.
  • the stacking containers In adaptation to the usual pallet size, the stacking containers are mostly designed as flat containers with a base area of 1,200 x 800 mm, with containers made of metal (steel or aluminum) being used exclusively for reasons of strength. It was perceived as a disadvantage that the containers are relatively heavy, often heavier than the goods to be transported.
  • the invention is based on the object of developing a container arrangement with plastic containers which can be stacked one on top of the other and which, despite the thin-walled and therefore lightweight construction, is capable of absorbing relatively high stacking and carrying loads.
  • the invention is based above all on the idea that, in the case of thin-walled plastic containers with a large base area, additional precautions are necessary in order to be able to absorb the high stacking and transport loads which occur during transport and in order to prevent impermissible deflections and connections under uneven loading to avoid.
  • At least one side wall is on the inside of the container Distance from the corners of the container, a further load column, essentially projecting vertically above the bottom of the container, is integrally integrated in the plastic material of the container, the lower end of which is connected to the bottom of the container and the upper end faces are arranged at a distance below the upper edge of the container, and an additional one Forms a support surface for the further container which engages with its bottom into the interior of the container from above.
  • the further load-bearing columns are expediently arranged in the center in two opposite broad side walls of the container, which is essentially rectangular in plan.
  • a further advantageous embodiment of the invention provides a concave stacking step which is molded into the outside of the container bottom and is open at the bottom and outside, the height of which is somewhat greater than the distance between the upper edge of the container and the end face of the load column and the depth of which is approximately the side wall strength corresponds.
  • a circumferential convex bottom edge step corresponding to the stacking step can be arranged on the inside of the container.
  • the load-bearing columns should have at least a thickness corresponding to the side wall thickness, a thickness corresponding to the depth of the base edge step having proven to be particularly expedient.
  • the load-bearing columns arranged in the corner area have a preferably flat boundary surface oriented obliquely to the adjacent side walls towards the inside of the container.
  • the load-bearing columns expediently form a cylinder segment molded into the cylindrically rounded corners.
  • a further improvement in this regard is achieved if the additional load columns arranged in the area of the side walls have a trapezoidal or part-circular cross-section tapering towards the interior of the container.
  • the stacking and transport forces are directed downward exclusively via the load columns, while the side walls have to absorb predominantly transverse loads due to the existing positive locking, the load columns additionally functioning as reinforcing ribs within the Take over side walls.
  • the side walls and the bottom surfaces can thereby be made relatively thin-walled.
  • the investigations carried out in this connection have shown that the side wall thickness should nevertheless be chosen to be greater than, preferably twice as large as, the base wall thickness. With a footprint of approximately 1
  • the load columns according to the invention only fulfill their function if they are vertically one above the other. If one takes into account that the side walls of the containers, which are made of plastic, preferably in the RIM process (Reaction Injection Molding), must have a draft angle, the load-bearing columns only come into play at relatively low side wall heights
  • the low container height has the advantage that the draft angle can be relatively small, so that the draft angle can advantageously be chosen between 0.4 ° and 1 °.
  • a bottomless container frame made of plastic, which has at least three, preferably four, connected to one another at frame corners, a common peripheral upper edge and lower edge has forming side walls, whose side walls on the inside of the container in the loading Rich the frame corners and possibly projecting at a distance from the frame corners, integrally integrated in the plastic material load columns, whose lower end extends to the vicinity of the lower edge and whose upper end face is arranged at a distance below the upper frame edge and a support surface for one of above with its bottom or its lower edge forms a container or frame which engages in the frame interior, and which contains a circumferential stacking step which is formed on the outside in the area of the lower edge of the frame and which is open to the outside, the height of which is somewhat greater than the distance between the upper edge of the frame and the end face of the load column and the depth of which corresponds approximately to the side wall thickness and / or the
  • a connecting strip can be attached, for example screwed or glued, from the inside in the area of the load bearing pillars.
  • the screw holes can be formed in the course of the manufacture of the frame or subsequently drilled. All connecting elements, including the strips and screws, are expediently produced from the same material in order to avoid problems with thermal expansion and to ensure simple recycling.
  • the bottomless container frames and containers can be produced with the same molds if an interchangeable insert in the form of a plate adapted to the base wall thickness is used for the base part.
  • a major advantage of this design is that containers of different heights can be produced with a single tool.
  • Another advantage is that the tall containers, which are composed of relatively low container elements, have vertical side walls in the assembled state, which are only somewhat jaggedly structured within the wall. In the overall production of a correspondingly high container, no vertical side walls would arise due to the necessary draft angles, and thus usable space and strength would be lost.
  • each side wall there is at least one recessed grip which is molded into the side wall and the container bottom, is open on the outside of the container to the side and downwards, and is closed towards the inside of the container.
  • the recessed grip can be formed by a bulge of material protruding from the side wall and from the bottom of the container into the interior of the container.
  • the recessed grip which is open towards the edge, also has the function of a locking element and a stiffening element, it being particularly advantageous if the recessed grip is arranged in the middle between two adjacent load columns.
  • the Grip recesses have a trapezoidal outline which is open at the bottom and widens, the side flanks of the trapezoidal grip recesses being inclined and the upper flank being oriented perpendicular to the side walls.
  • the central load-bearing column serves as an extension of the corner load-bearing columns of the smaller containers. Since the smaller containers also have to absorb smaller forces, and because of the additional partition a stiffening is achieved, the existing load columns are sufficient for support.
  • the middle load-bearing column only has to be made wide enough so that a direct load transfer via the load-bearing columns is possible.
  • large containers can also be stacked on smaller ones. This can be done in that a suitably shaped between the containers Cover plate is placed.
  • the container bottom has a channel which extends between two opposite load-bearing columns arranged in the center of the side walls and is open at the bottom and corresponds in depth to the height of the stacking step, and that the container thus has two other containers which are arranged closely next to one another, preferably half as large, are stacked in such a way that their groove overlaps the upper edges of the mutually facing side walls of the other containers and with their centrally arranged load columns on the corner load columns of the other containers located below is supported.
  • a pallet is provided for the form-fitting reception of a container or stack of containers, it being possible to arrange cams which protrude on the surface of the pallet and engage positively with the recesses of a container seated thereon.
