Definitions

  • the present invention relates to lids for fruit boxes, particularly boxes for transporting tomatoes for sale.
  • Fruit boxes made of plastics materials are available, such fruit boxes having walls and a base perforated by many holes and having rigid upstanding columns at the corners thereof so that when the boxes are stacked each box is held well above the box below it so that air can circulate.
  • fruit boxes are very bulky to store before they are filled and are difficult to stack.
  • the present invention provides a lid of moulded plastics material for a fruit box, said lid comprising a rim and skirt adapted to fit the top edge of a fruit box and a plurality of protrusions extending from the rim in the opposite direction to the skirt.
  • a lid for a rectangular fruit box there are at least six protrusions.
  • at least some of the protrusions are provided at the top thereof with one or more small projections which can embed themselves in the cardboard base of a box placed on top of it.
  • the skirt is slightly flared and the protrusions have a hollow tapering form so that one lid can be nested inside another.
  • the top central portion of the lid inside the rim is substantially open, or is formed of a lattice of plastics material.
  • the invention offers many advantages over known constructions.
  • the protrusions and the open central portion of the lid permit adequate circulation of air around and between the fruit. Because the protrusions are located on the lid and not on the base the boxes can conveniently be stacked flat as blanks or can be made nestable so that they occupy a minimum of space when not in use. Furthermore, the lids also are nestable.
  • the lid 1 of moulded plastics material and of rectangular shape comprises a rim 2 and a skirt-3 depending therefrom.
  • the skirt 3 is slightly flared.
  • the protrusions are frusto-conical in shape and each of the protrusions is moulded integrally with the rim and is hollow so that the interior of the protrusion is open from below.
  • the top of each protrusion is formed as a platform with a small projection or spike 5 standing proud of the platform surface.
  • a reinforcing framework 6 of plastics material as shown in the drawing is desirable.
  • the areas 7 adjacent to the rim may be occupied by a lattice of plastics material as an additional part of the framework.
  • the end walls 8 of the skirt may suitably be provided with flaps 9 which can be pushed inwardly by manual pressure so that the top edge of the flap engages a slot 10 in the corresponding end wall of the box 11.
  • a conventional rectangular box 11 of cardboard has a dividing wall 12 across the centre between the long walls.
  • fruit e .g. tomatoes
  • a sheet covering is placed on top and then the lid 1 is closed down on to the box.
  • the centre pair of protrusions 4 are supported from below by the dividing wall 12. After another box has been filled, it is stacked on top of the lid, and the protrusions 4 hold the upper box above and spaced away from the lower box.
  • the spikes 5 become embedded in the cardboard bottom of the upper box so that slipping of the boxes is inhibited.
  • the upper box stays level even if it is offset lengthwise relative to the lower box and so misses the protrusions 4 at one end of the lid of the lower box.
  • An air space equal to the height of the protrusions is left open between successive boxes in a stack.
  • the cardboard boxes Prior to use, the cardboard boxes may be stored as flat blanks in the usual manner, and the lids may be stacked one inside the other, the flared skirts permitting successive lids to nest inside one another and the hollow interiors of the protrusions on each lid accommodating the corresponding protrusions of the next lid.
  • the skirt in the region of the corners may be extended downwardly a greater distance than the remainder of-the skirt so as to increase the strength of the lid and to assist in locating it on the box, as shown in Figure 4 of the drawings.
  • substantially all of the top of the lid is formed of a lattice 7 of plastics material.
  • the construction shown in Figure 3 is similar except that a seventh protrusion 4 is provided in the centre of the lid and is moulded integrally with a supporting cross-member 14. This protrusion and the cross-member 14, when the lid is in use, are supported by the dividing wall 12 of the fruit box.
  • the lid is preferably injection-moulded from polypropylene or polystyrene or other suitable plastics material.
