Definitions

  • the invention relates to a plastics crate or tray having upstanding walls and a bottom particularly for transporting hard fruit, the outer side of the bottom of said plastics crate or tray being reinforced by means of at least one hollow elongate plastic reinforcing member being connected with said bottom.
  • Such a plastics crate or tray formed by welding a bottom part and upstanding walls, the elongate hollow reinforcing members being also welded to the bottom is known from DE-A-1.948.503.
  • This crate presents the disadvantage that the different parts have to be separately moulded and subsequently assembled which makes the crate or tray expensive and moreover a rather thick bottom is required in order to meet the requirements that the bottom is sufficiently rigid thus providing the so-called "trampoline" effect during transporting of fruit;
  • the bottom is not allowed to sag under the load of the contents of the crate or tray when its underside is unsupported even after a long period of time; the bottom should be so flat so that it cannot form impressions on the contents of the crate or tray and the bottom of the crate or tray should have such a configuration that no dirt can gather at that location, whilst an incidental contact between subjacent fruit and said bottom should not cause an impression of the bottom in said fruit.
  • the hollow reinforcing member comprises at least one pair of opposite walls conveying towards the centre of the reinforcing member and the bottom of said reinforcing member is provided with at least one member aperture, the area near said member aperture being reinforced by reinforcing ribs.
  • a reinforcing member comprising at least one pair of opposite walls of the reinforcing member allows an easy retraction of the core members contrary to core members having substantially the same cross section over their whole length as such core members get clamped in the member due to shrinkage of the moulded plastic material.
  • tray or crate should be provided with a rather thin bottom in order to save plastics and to avoid long cooling times elongate members of a substantial cross section should be used requiring heavy core parts.
  • the presence of a member aperture in the bottom of the elongate member now allows to support the heavy parts.
  • the crate or tray according to the invention may be provided with a thin bottom as the hollow members being integral with the bottom due to the injection moulding allows the use of thinner bottom than bottoms provided with reinforcing members welded to the bottom.
  • An injection moulded plastics tray or crate comprising a bottom being connected through downwardly ccombined extending bottom parts with the upstanding walls is known per se from FR-A-1.452.995.
  • the outer side of the bottom is integral with parallel reinforcing ribs extending perpendicular to the bottom.
  • This crate or tray presents the disadvantage that an appropriate reinforcement of the bottom requires many reinforcing ribs and as these ribs are rather sharp edged fruit may be easily damaged by these ribs during stacking such crates or trays.
  • vent apertures are provided in the lower portions of the bottom which simultaneously provide an outlet for liquid, such as washing liquid and of dirt, if any.
  • the shape of the bottom of the plastics crate or tray according to the invention is chosen in such a manner that said crate or tray may at least rest upon a floor through parts differing from a hollow reinforcing member according to the invention.
  • the latter measure is very convenient, as damage of fruit due to the presence of such a reinforcing member according to the invention, need not necessarily be taken into account when entirely filling a plastics crate or tray and subsequently stacking a second filled crate or tray thereupon.
  • the lower side of the circumference of the bottom comprises a bottom edge into which the hollow reinforcing members open.
  • the height of said bottom edge is preferably such that a reinforcing member cannot rest upon the floor, so that the reinforcing member a members are unable to distort the bottom of the crate or tray, thus causing a damage of its contents.
  • the plastics crate or tray of fig. 1 consists of two longitudinal side walls 1 and two transverse side walls 2 being interconnected, by means of preferably hollow corner parts 3 for supporting superposed trays or crates; the plastics crate or tray further comprises a bottom 4 connected with the longitudinal side walls 1 and the transverse side walls 2.
  • each elongate reinforcing member 5 has two open ends.
  • the plastics crate or tray according to the invention comprises venting apertures, reinforcement ribs, handles and so on as known per se and which will not be described.
  • Fig. 2 shows a cross-section according to line II-II in fig. 1.
  • the elongate reinforcing member 5 converges towards the centre from both its two open ends.
  • the tapering embodiment of the elongate reinforcing member facilitates the removal of injection moulding cores and prevents furthermore damages to the walls of a member 5.
  • Fig. 2 also shows that the centre of the member presents an aperture 7 formed during the injection moulding process by a support (not shown) of the injection moulding mould in order to support the extremities of cores (likewise not shown) around which core an elongate reinforcing member 5 is injection moulded.
  • reinforcement ribs 8 are provided in the vicinity of the aperture 7.
  • Fig. 3 shows a partial cross section of the plastics crate or tray according to line III-III in fig. 1.
  • two elongate reinforcing members 5 are situated above the plane through the free ends of a circumferential bottom edge 6, whilst the bottom 4 inclines from the member or members 5 towards bottom edge portions running parallel with said member or members.
  • bottom apertures 9 are provided for an outlet of liquid and moisture and for obtaining some ventilation.
  • the bottom part between the two parallel members 5 is a flat bottom part.
  • one or more apertures 10 in the bottom edge 6 allows a ventilation and outlet of e.g. washing or leakage water from the part of the floor below the plastics crate or tray.
  • Fig. 4 is a botton view of an area including and surrounding aperture 7, of a reinforcing member 5. This figure also shows the reinforcing ribs 8, as previously illustrated in figures 2 and 3, each rib at least extending between two walls of a reinforcing member and the converging shape of a member 5.
  • apertures 7 formed during injection moulding due to the presence of supports for the cores as required for forming the members 5. These apertures 7 , may be closed by means of covers 11 with nocks 12 engaging the bottom part of a member 5.
