Definitions

  • This invention relates to open-topped boxes formed from sheet material such as cardboard.
  • Open-topped cardboard boxes are used for the packaging of tomatoes, such boxes affording protection for the goods during transport and storage thereof and also providing containers from which the tomatoes can be displayed and dispensed for sale to customers.
  • Known such tomato boxes are formed from appropriately cut and folded cardboard sheets and have rectangular bases bounded by side walls, inwardly turned rims being provided at the top edges of the longer side walls and flaps being folded back against the inner surfaces of the side walls.
  • the rims and flaps provide a reinforcing function but it has been found that, despite this, the overall strength is not always adequate, particularly having regard to the fact that, in use, many heavily laden boxes may be stacked one on top of another; and it is not uncommon for partial collapse of boxes and consequent damage to the contents thereof to occur.
  • An object of the present invention is to provide an open-topped box which has improved structural strength.
  • an open-topped box formed from sheet material and having a base of rectangular planform bounded by upstanding first and second pairs of opposed side walls, at least one side wall of said first pair having an inturned rim at the upper edge thereof, characterised in that said at least one side wall has an upright reinforcing strut, formed from folded said sheet material, extending on the inner side of said side wall between the base and the rim, which rim is attached to the opposed side walls of the said second pair.
  • the two opposed longer side walls have rims thereto and are provided with respective said struts in the central regions thereof.
  • the or each strut may be defined by sheet material which is folded to form, in itself or together with the associated side wall, a hollow structure, particularly a hollow square-section tube.
  • all side walls may have inwardly turned rims thereto and these may be formed integrally with each other.
  • the box of the invention is formed from a single sheet of material and, in this case, the or each strut may be formed from a flap which is cut from the region of the sheet which forms the open top of the box thereby to achieve economic usage of material.
  • the sheet material used in forming the box of the invention will most preferably comprise cardboard by itself or appropriately coated, it is of course to be understood that the invention is not restricted to this and any other suitable material or combination of materials may be used. Also, whilst the box of the invention is particularly suitable for use in the packing of tomatoes, it can of course be used with any other suitable goods.
  • the box which is intended for use in the packaging of easily damaged goods such as tomatoes or other fruit or the like, has a rectangular base 1 bounded by four upstanding side walls 2, 3.
  • the box also has a top wall 4 with a central rectangular portion 5 cut out therefrom to define integral inwardly turned rims 6, 7 at the upper edges of the side walls 2, 3.
  • the opposite shorter side walls 3 have elongate slots 8 therein to define handgrips.
  • the opposite longer side walls 2 are provided with ventilation holes 9.
  • each such folded sheet has a central vertical channel section 11 with flaps 12 on opposite sides.
  • the flaps 12 lie against the inner side of the pertaining side wall 2 and the channel section 11 defines with such side wall 2 a vertical square-section tube terminating at its upper end against the underside of the pertaining rim 6 and terminating at its lower end against the base 1.
  • the flaps 12 have holes 13 therein which coincide with the ventilation holes 9 in the side walls 2. Secure location of the flaps 12 is achieved by engagement of projecting tabs 25 on the flaps with slots 26 in the side walls 2.
  • the box is manufactured from a box blank as shown in Fig. 2, which is appropriately cut and provided with fold lines.
  • the box base 1 is defined by the region 14, the shorter side walls 3 are defined by strips 15 which fit over strips 16, and the longer side walls 2 are defined by strips 17, 18 together with edge piece 19 which tucks on the inner side of the strip 17.
  • Each strip 15 has end flaps 20 which tuck in against the inner sides of the strips 17, 18 to reinforce the corners and longer side walls 2 and to assist in holding the assembled box structure together.
  • a region 21 of the blank has a cut 24 in the centre thereof which is almost wholly rectangular and defines the rimmed open top of the box, such cut leaving two structures 22, held at positions 23.
  • These structures 22 are provided with fold lines 27 and slits 28 and can be folded to define the struts 10. In the assembled box, the ends of the flaps 12 of the struts 10 abut the ends of the adjacent folded corner flaps 20.
  • the assembled box may be held together by stapling and/or glueing as appropriate.
  • the box can be assembled in a simple manner from the single box blank and it will be noted that little wastage of material is involved, particularly because the struts 10 are formed by the structures 22 which are cut from the part of the region 21 of the blank which provides the open top of the box.
  • the box When assembled the box has great vertical strength as a consequence of the struts 10 which extend between the rims 6 and the base 1. Strength is of course also derived from other features of the box structure particularly the integral rim arrangement and the corner flaps 20. Many heavily laden boxes can therefore be stacked one on top of another with little tendency for damage to be caused to the contents thereof due to partial collapse of the boxes.
  • Figs. 3 and 4 in which like parts are numbered as in the Figs. 1 and 2 embodiment, the box shown therein has a rim 6 attached to each long side wall 2, and both rims 6 are attached to both short side walls 3.
  • the struts 10 are formed from the sheet material which is cut to form the open top 5, thus providing for each strut 10 two upstanding portions 11 and two flaps 12 which are secured to the base 1 by adhesive or staples.
