Definitions

  • the invention relates to an injectionmoulded plastics crate or tray having upstanding walls and a bottom,particularly for transporting hard fruit.
  • Such a crate or tray has to meet the requirements that the bottom is sufficiently rigid thus preventing 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 not 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 underside 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 present invention now aims to overcome these disadvantages and this is attained according to the invention in that such a plastics crate or tray is characterized in that the bottom of the crate or tray is reinforced by means of at least one case, the upper wall of said case being integral with the bottom.
  • the plastics crate or tray in accordance with the invention presents the advantage that a proper reinforcement of the bottom is obtained, whilst the case or cases can be given such a shape that fruit resting thereupon, will not be damaged or impressed by said case or cases.
  • the case or cases are formed simultaneously with injection moulding the tray or crate by using male moulding cores.
  • cores In order to retract the cores easily and without damaging the inner walls of the case or cases opposite walls of a case preferably converge towards the centre of a case.
  • the case or cases and at least the lower wall thereof comprises at least one case aperture through which the core can be supported during the injection moulding operation.
  • this area is preferably reinforced by reinforcing ribs.
  • the bottom of the crate or tray preferably inclines from at least one of the upper walls of a case towards the side regions of the bottom, running parallel therewith.
  • the provision of vent apertures in the lower portions of the bottom simultaneously effects an outlet for liquid, such as washing liquid and of dirt, if any.
  • the shape of the bottom of the plastics crate or tray is chosen in such a manner that said crate or tray may at least rest upon a floor through parts differing from a cas6 or cases according to the invention.
  • the latter measure is very convenient, as damage of fruit due to the presence of case 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 case or cases open.
  • the height of said bottom edge is preferably such that a case or cases cannot contact the floor at the location where a crate or tray rests upon said floor, so that the case or cases 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. Underneath the bottom 4 two hollow cases 5 are provided, which preferably open into a circumferential bottom edge 6 of the bottom 4 so that each case 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 case 5 converges towards the centre from both its two open ends.
  • the tapering embodiment of the case facilitates the removal of injection moulding cores and prevents furthermore damages to the walls of a case 5.
  • Fig. 2 also shows that the centre of the case 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 a case 5 is injection moulded.
  • reinforcement ribs 8 are provided in the vicinity of the case aperture 7.
  • Fig. 3 shows a partial cross section of the plastics crate or tray according to line III-III in fig.. 1.
  • two cases 5 are situated above the plane through the free ends of a circumferential bottom edge 6, whilst the bottom 4 inclines from the case or cases 5 towards bottom edge portions running parallel with said case or cases.
  • bottom apertures 9 are provided for an outlet of liquid and moisture and for obtaining some ventilation.
  • the bottom part between the two parallel cases 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 port of the floor below the plastics crate or tray.
  • Fig. 4 is a bottom view of an area including and ⁇ surrounding aperture 7, of a sleeve 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 case and the converging shape of a case 5.
  • case apertures 7 formed during injection moulding due to the presence of supports for the cores as required for forming the cases 5. These case apertures 7 may be closed by means of covers 11 with nocks 12 engaging the bottom part of a case 5.
