Definitions

  • the invention relates to a stackable container of the type as it is referred to in the preamble of claim 1.
  • the invention relates to containers intended for repeated use, including the fact that the containers must be returned from an emptying location to a filling location.
  • Known containers are concerned which combine the possibilities of stacking one on top of the other, which means that empty containers can be stacked one inside the other with a view to taking up as little space as possible and that the containers can be stacked on top of one another when filled.
  • This is achieved by the asymmetrical design of the containers, so that by interlocking positioning of two containers, they can be stacked and - based on the container below them - can be stacked on each other with a rotation of 180 ° around a vertical axis.
  • the asymmetry can be seen in the fact that two different groups of support blocks are provided on opposite side edges, preferably gable ends of the container, so that these groups of support blocks alternately engage with one another and also between one another.
  • the object of the present invention is essentially to provide a container with a rectangular shape, which can be used open - without a lid - and which is designed such that several containers can be stacked one inside the other or on top of the other, including a crosswise one Stacking of similar containers should be possible.
  • this object can be achieved by a container according to the characterizing part of claim 1.
  • a container manufactured according to the invention can be placed in the filled state on two containers with a corresponding shape and can be held in this position without the risk of lateral movements, tipping or turning.
  • FIG. 1 shows a stackable container 11 with an essentially rectangular shape and two long side walls 12, 13, which generally have twice the length of the corresponding short gable walls 14, 15.
  • the side walls 12, 13, the gable walls 14, 15 are designed to be inclined in order to stack them in a known manner to enable the container 11.
  • a peripheral edge flange 16 with an edge extension 17 pointing downward is provided on the upper edge of the side or gable walls 12 to 15.
  • the edge extension 17 is reinforced with integrated extensions 18, which have approximately the same height extension as the edge extension 17 mentioned.
  • the side wall 12 has a flat, uninterrupted surface, both inside and outside.
  • the adjacent gable wall 14 is also flat and not interrupted.
  • an indentation 19 is provided in the corner area, which extends from the bottom of the container 11 up to the edge flange 16.
  • a corresponding indentation 20 is arranged on the other side of the gable wall 14.
  • the indentations 19 and 20 each form an upper support surface 21 or 22, which is lowered or set back approximately by the thickness of the material used for the side and gable walls with respect to the upper edge (edge flange 16) of the container 11.
  • indentations 23 and 24 are provided at a certain distance from one another and from the adjacent corners of the container 11, which distance exceeds the corresponding width extension of the indentations 19, 20 on the opposite gable wall 14.
  • the indentations 23 and 24 are shaped like ribs or the like, each of which forms a support surface 25 or 26 at its upper end, which, like the support surfaces 21, 22 on the indentations 19 and 20, respectively, is correspondingly lowered relative to the upper edge (Edge flange 16) of the container are executed.
  • the walls in the region of the indentations 19, 20, 23 and 24 generally have the same material thickness as the other wall parts of the side or gable walls.
  • outer depressions are formed in the side or gable walls of the container with a shape and extension opposite to the indentations.
  • a container to be placed By pivoting the described container through 180 ° about its vertical axis, a container to be placed can be placed (stacked) on the upper side of a container in a known manner, since the lower edge of the gable wall 14 bears against the carrying surfaces 25, 26 of the indentations 23 and 24, respectively and the outer corners of the lower edge of the gable wall 15 lie against the bearing surfaces 21, 22 of the indentations 19 and 20, respectively.
  • an indentation 27 is provided on the long side wall 13, which forms a support surface 28 at the upper end, which lies at the same height as the support surfaces 21, 22, 25 and 26.
  • containers 11 When containers 11 are stacked crosswise, as shown in FIG. 2, two containers 11 are placed side by side as the basis for an overlying container 11 arranged transversely thereto, that is to say a container which is rotated by 90 ° about its vertical axis in relation to the containers underneath is.
  • the containers 11 located underneath are placed in such a way that the carrying surfaces 28 are on opposite sides of the two containers 11 arranged next to one another.
  • two opposite support surfaces 28 are formed, which have a distance from each other which corresponds to the length of a container 11, so that these support surfaces 28 serve as a support for an overlying container 11.
  • drip channels are provided on the container in the upper edge.
  • two drip channels 30, 31 are provided symmetrically to one another and to the outside of the edge (edge flange 16). These drip channels 30, 31 are designed in the form of grooves that extend into the supporting surface 28 continue.
  • a drip channel 32 is provided starting from the support surface 28 in the area of the upper corner between the long side wall 13 and the support surface 28.
  • a drip channel 33 is formed in the region of the indentation 24 and extends into the supporting surface 26. The formation of drip channels 30 to 33 serves the purpose of draining any water or other liquid to the outside of a stack of containers to prevent water or other liquid from flowing into the underlying container.
  • a groove 29 is provided in the middle and parallel to the gable walls 14 and 15 on the outer side of the bottom wall 34, the depth of which is equal to that or greater than the height difference between the support surfaces 21, 22, 25, 26 and 28 on the one hand and the subsequent upper edge region of the edge flange 16 on the other hand and their width is equal to or greater than twice the width of the edge flange 16 in the region of the long side walls 12 and 13 is.
