Definitions

  • a container is to be re-usable, it is desirable that the container when it is being returned empty should occupy less space than when it is in its operative mode carrying goods.
  • the present invention provides a container base suitable for such purposes.
  • the base comprises a rectangular base piece, upstanding side walls surrounding the base piece and tapered outwardly to allow nesting of container bases, a pair of opposite side walls having a slot on their centre line extending at least half the height of the walls from their free edge, the walls of said pair on one side of said centre line being wider apart than said walls on the other side of said centre line by at least twice the thickness of each wall of said pair.
  • Ribs may be formed in the side walls to give them strength, particularly when the base is moulded from plastics material, thus preventing the side walls sagging from their desired shape.
  • the ribs on the side walls parallel to said centre line are arranged symmetrically about their centre, the number and size of the ribs on the two opposite side walls parallel to said centre line being equal. The number can be odd or even.
  • the base piece is preferably formed with portions at a plurality of different levels, in order to give rigidity to the base piece, to provide bearing surfaces and to provide a nesting arrangement when two bases are placed base piece-to-base piece (with their mouths facing away from each other) and yet allowing the nesting portions to be easily disengaged.
  • a continuous groove may extend around the base piece at the junctions with the walls to receive box wall panels. Without the panels two container bases can interfit mouth-to-mouth to form a shallow container. If such bases are drawn apart and box wall panels inserted between the continuous grooves, a much deeper container is formed.
  • the container base is a tray moulded from a sheet of plastics material with a rectangular base piece 11 and side walls 12, 14 of uniform height.
  • the side walls are tapered very slightly outwards from the base, so that a plurality of trays will nest in each other, taking up minimum space in the nesting arrangement.
  • the base piece 11 of a tray is formed on its underside with distributed bearing surfaces for bearing on a horizontal plane without distortion of the tray.
  • the tray is designed so that a pair of trays can fit together open mouth-to-open mouth to form a strong container. Furthermore, a plurality of such containers can be stacked one on top of the other and protrusions on the undersides of adjacent trays will interfit to prevent relative lateral movement of aligned trays.
  • Each tray is formed with open-ended slots 15 at the mid points of two opposite side walls 12, the slots extending at least half way from the top of the wall at right angles to the base panel.
  • the slots 15 lie on the centre line 16 of the tray. On one side of the centre line 16 the tray is slightly wider than on the other side, by an amount equal to the thickness of the side walls. The “bulge" of this extra width is shown at 18 in Fig. 3. When two trays are placed mouth to mouth with the narrow end of the top tray over the wider end of the bottom tray, the trays will fit together with each narrow end resting in the wider end of the other tray, and the slots 15 interfitting (see Fig. 4).
  • each slot is V-shape, the blind end 15" of the slot extending from the apex of the V being parallel-sided.
  • the free edge of each side wall 12-14 will rest on the base panel 11 of the opposite tray.
  • the resulting container will enclose a volume equal to that enclosed by a single tray up to the level of the top of its side walls.
  • the walls are ribbed.
  • the ribs 21 are aligned - i.e. an outward-going rib lies opposite an outward-going rib on the opposite wall.
  • a handle 13 is provided at the centre of the walls 14 which can be removed if necessary to assist stacking empty trays.
  • the ribs 22 on each wall must be symmetrically arranged about the slot 15 in that wall, in order that these ribs on two trays can interfit in the Fig. 4 arrangement.
  • the ribs 22 are preferably equispaced as illustrated - i.e. the width of each outward-going rib is equal to the width of the space between ribs. There is no rule governing the relationship of the ribs on wall 12.
  • the ribs 22 could be arranged so that one rib or one space between ribs straddles the slot 15 (not illustrated).
  • the base piece 11 shown in Fig. 1 is rectangular and has areas arranged at at least four different levels. In use these levels are horizontal. In general each area having a horizontal component has a reference number with three digits, of which the first digit indicates the level of that component. Considering a tray with its mouth opening downwards, the top levels are those of the bearing surfaces which have reference numbers in the range 100 - 199. The intermediate levels have reference numbers in the range 200 - 299. The next lower levels have reference numbers in the range 300 - 399. The lowest levels have reference numbers in the range 400 - 499.
  • the components with reference numbers in the range 400 - 499 form the supporting plane for a liner defining the base of the tray, the effective storage volume of the tray being the product of the liner area and the height of the side walls above the components with reference numbers in the range 400 - 499.
  • the horizontal surface on which the underside of components 100 - 199 can bear may be that of a conventional pallet.
  • the various components 101 - 199 are individually discontinuous, it is pointed out that across the width of the tray and across the length of the tray there is at least one of the components 101 - 199 present at every point. This means that the tray will move on a roller conveyor without allowing a roller to enter a space between two of the components 101 - 199.
  • a larger volume container can be formed by placing panels in the peripheral grooves 150 immediately inside the side walls, the panels spacing the trays apart. The four panels may be joined at the corner edges of the container volume.
