Definitions

  • the invention relates to a crate or tray, a number of which can be stacked on top of each other into a stable stack, comprising a generally rectangular bottom, two pairs of side walls having different lengths and standing at right angles to the bottom, the side walls being connected to each other at the corners of the tray and being essentially the same height, and at least at these corners, along the bottom sides thereof, a horizontally running supporting ledge bounded at its inside by a vertically running border formed so that when a number of trays are stacked on each other, a top tray always rests with its supporting ledges on the top sides of the walls of a tray lying underneath, the vertically running borders gripping behind said top sides.
  • a tray of this type is generally known.
  • a stackable tray of a second type having at each of the four corners a corner pillar, of which the top part projects beyond the top edges of the tray, and of which the bottom end forms a recessed supporting face at the bottom of the tray, so that the tray can rest with said supporting faces on the tops of the corner pillars of a tray lying underneath.
  • This type of tray has in the bottom side horizontal ledges which run along the short and long sides, are bounded by vertical borders, and merge by means of steps into the above-mentioned lower-lying supporting faces.
  • the disadvantage of the known trays is that they cannot be stacked with trays of a different type, so that only trays of one and the same type can be stacked on top of each other into a stable stack.
  • GB-A-952979 corresponding to the preamble of claim 1 discloses a stackable transport crate made of plastic material for bottles which can be piled together with other types of bottle crates as for instance with crates of wood.
  • the crate consists of a stiff upper frame and rigid bottom frame which are rigidly connected with each other by means of corner supports.
  • the bottom frame comprises a bottom flange projecting downwards and which fits into the inside of a wooden crate whereas the upper frame has upright flanges which are interrupted near the corner supports so that a wooden crate placed on top fits between said flanges
  • the object of the invention is to produce a tray of which a number can be stacked on each other into a stable stack, and which can be stacked both with trays of the first type mentioned in the preamble and with trays of the above-mentioned second type.
  • the supporting ledge is enlarged at each corner by means of the vertically border being displaced inwardly towards the centre of the bottom, for the formation of supporting faces, each of said supporting faces being provided with a recess and on either side of the top edge of each corner an upwardly projecting step is formed and on the top edge of each corner is located a projection, whereby the recess of each supporting face is able to accommodate the projection of an underlying tray, whereby a crate having corner pillars can be stacked underneath the above mentioned tray so that the supporting faces rest on the corner pillars and the vertically running borders engage behind the inner face of the pillar, and whereby crates having ledges on either side of each corner bounded by vertical borders at their bottom are able to be supported on the steps of the above mentioned tray.
  • An upward-running step is preferably formed on either side of each corner, in the supporting ledge at the bottom of the tray, said steps being able to receive the above-mentioned steps in the top edges of a tray lying underneath.
  • the steps in the top edges are advantageously of a width which is less than the width of the top edges.
  • top sides of the steps in the top edges of the shorter sides of the tray preferably merge into each other.
  • the tray has a bottom 1, two long side walls 2, and two short side walls 3, which are joined to each other at the corners 4 of the tray.
  • Supporting faces 5, which are provided with grooves and merge via steps 6, 7 into supporting ledges 8, 9, are formed at the bottom sides of the corners 4, the supporting ledges 8 and the supporting ledges 9 being bounded at the inside by a vertically running border 10, 11.
  • the borders 10 and 11 are connected to each other at the corners 4 by means of the border parts 12.
  • Each supporting face 5 has formed in it an arch-shaped recess 13 which can accommodate a correspondingly arch-shaped projection 14 on the top edge of a tray lying underneath, so that a stable stack of trays can be built up.
  • steps 15, 16, which can receive the steps 6, 7 of a tray lying above, are formed.
  • the steps 15 and 16 are of a lower width than the top edges of the tray, while the top sides of the steps 16 merge into each other to form one continuous top side 17.
  • the known tray of the first type has at the corners thereof supporting ledges 18 and 19 which are bounded at the insides by the vertical borders 20, 21.
  • the ledges 18 rest on the top edges 15′ of the steps 15 and the ledges 19 on the continuous top side 17 of the steps 16, while the borders 20 grip behind the steps 15 and the borders 21 behind the steps 16, so that a stable stack is obtained.
  • top sides 22 of the corners of the tray of the known first type are designed as an angular bearing face on which the bearing face 5 of a tray according to the invention lying above can come to rest, while parts of the borders 10 and 11 and the entire border 12 grip behind the bearing face 22.
  • the tray of the second known type has at each corner a corner pillar 23 which projects beyond the top edge of the tray, and which forms a recessed supporting face 24 at the bottom end.
  • This tray also has at the bottom side, on either side of the recessed supporting face 24, supporting ledges 25, 26 which are bounded by the borders 27, 28.
  • the first-mentioned tray rests at 24 on the top sides of the corners of the tray according to the invention, the borders 27 and 28 gripping behind the steps 16, 15 of the tray according to the invention.
