  • This arrangement together with the wall with increased draft angle provides an asymmetric geometry, thus enabling stacking containers simply by placing the container directly upon the underlying container, where the locking tabs 112 stabs into the respective stacking recesses 124 of the container located above. This is illustrated schematically in Fig. 12, which show a stack of filled containers.
  • each tab is preferably sufficiently smaller than the cross-section area of the stacking recess 124, thus leaving a space between the stacking tab 112 and the stacking recess 124, allowing the containers to move a little but without allowing the containers to slide out of engagement.

  • the increased draft angle a of the first end wall 103 provides a space 122 between stacked containers (Fig. 5).
  • This space 122 allows air between to containers in a process of being stacked to escape. Accordingly, friction from air resistance is reduced drastically during stacking, and containers can be stacked more efficiently.
  • Another substantial advantage of this end wall construction is that containers can be stacked closer to each other than prior art containers. Accordingly, a higher number of containers can be stacked per height unit than known heretofore, thus allowing transport or storing of a higher number of empty containers. Accordingly, return transport and/or storage of containers according to the invention can be performed in a more efficient manner.
  • Fig. 5 illustrates a part of a compact stacking mode.
  • the grip 105 is formed as a recess in the end wall (here the first end wall 103), this forming an upper lip 106-1 and a lower lip 106-2.
  • the lips 106-1 and 106-2 are formed with a chamfered end in direction downward and with a similar angle of inclination. This arrangement improves stability of a pile of compactly stacked containers where the containers are in a grip-to-grip contact.
  • a group (node) 300 of containers are interconnected in a horizontal plane by a node connection means 200, where each node contains four containers.
  • the node connection means 200 is formed with a plate or disc section 204 with four downwardly directed tabs 201 arranged in a mutually equal distance at the periphery of the plate.
  • the respective tabs 201 are extending into the corner slot 113 of the respective juxtaposed container 100.
  • a handle 202 is formed on the upper part of the node connection means for easy access when connecting or disconnecting containers.
  • the node connection means is formed with a recess in its middle, thus leaving a space 203.
  • the space 203 makes it easy to grip the node connection means 200 and to unlock - or lock - a container node in a simple manner.
  • Stacked node connection means 200 is illustrated in Fig. 10.
  • Each tab 201 do preferably exhibit at its side facing the internal space 203 a protrusion 205.
  • This protrusion provides a snap connection where the tabs slide slightly outwards when pushing the tabs 201 down into the respective corner slot 113 when passing the rim 115 of the container, and moves back to the resting position when the connection means 200 has reached its locking position.
  • the tabs will in a connected state make an engagement with the underside of the corner slot 113 and increases the stability of the interconnected containers.
  • the node connection means enables interconnection of four containers (one node) and provide a stable group of containers. It should be noted that it is also possible to interconnect two or more nodes in the same manner, thus enabling grouping of a large number of containers.
  • Fig. 11 illustrated numerous container nodes 300 stacked in a compact mode and secured by at least one node connection means 200 at the uppermost node 300. However, preferably some or all of the container nodes are interconnected by respective node connection means 200, thus providing a best possible stability in a node pile. In Fig. 11 a total of 21 container nodes 300 are stacked in a very compact and stable manner. In this way, there is no need for any stabilizing plastic wrapping or similar, which simplifies handling of containers and container stacks in an environmentally advantageous manner.
  • the container in accordance with the present invention provides several advantages compared to prior art containers. Firstly, the increased draft wall angle of at least one of the walls compared to the remaining walls simplifies stacking of containers within each other in a compact stacking mode by letting air out of the space between the walls, having increased draft wall angle, of adjacent containers while a container is lowered down into an underlying container. Stacking of prior art containers having closed walls and bottom produces air friction during stacking because there is less space available for air to escape during stacking. Moreover, the deviating draft angle arrangement allows for a more compact pile of stacked containers. As a result, more containers can be stored and/or transported per unit volume.
  • the container node connection means, several containers can be interconnected, four containers per node.
  • This node connection means makes it possible to prepare a pile of container nodes in a very stable manner, thus eliminating the need for a plastic wrapping or similar.
  • the grip arrangement formed as a recess in the end walls and with downwardly tapered noses provides a firm support for containers stacked in a compact mode, where only the grip parts of adjacent containers are in contact with each other.
  • the lack of prior art ribs and edges combined with drainage means simplifies cleaning of the container compared to prior art containers. Modifications
  • the container in accordance is illustrated with a rectangular horizontal cross-section.
  • the container may also exhibit different cross-sections, such as square.
  • the wall having a larger draft angle than the other walls is an end wall.
  • the increased wall draft angle does not have to extend all the way down to the bottom of the container. It is also conceivable to increase the draft angle only at an upper part of the wall.
  • only one wall is provided with a larger draft angle than the remaining walls.
  • the container is illustrated as a non-collapsible one, the invention is not limited to this. It is also conceivable to provide a collapsible embodiment by introducing hinge means from the prior art. Moreover, the container is illustrated with four drainage holes in the bottom at the four corner sides. However, while the illustrated embodiment is preferred, the drainage holes are optional and may further be limited to less than four.
