Definitions

  • the present invention refers to boxes to contain articles such as, for example, fruit and vegetables, which can be stacked one on top of the other.
  • Boxes produced, typically, in plastic material and used to contain fruit and vegetables which, when filled with goods, are placed one on top of the other (both for transportation and for display) forming a stack are well-known in the art.
  • Some types of said boxes having a parallelepiped shape, are provided with a projecting element at the corners and upper edge which runs towards the inside of the box and serves as support for another box which is placed on top of the first. Furthermore, these conventional boxes are provided with several horizontal ribs around the external perimeter which confer adequate mechanical resistance to the structure, making it possible to stack the full boxes. To stack the boxes, the internal projecting elements of the lower box engage with the external ribs nearest to the bottom of the upper box, in such a way as to support it.
  • Object of the present invention is to supply a box to contain articles which does not have the above-mentioned limitations with reference to the known state of the art.
  • the box 100 is made, preferably, in plastic material (for example, polypropylene PP) but can also be produced in other material such as, for example, metallic material.
  • plastic material for example, polypropylene PP
  • other material such as, for example, metallic material.
  • molding techniques known to the skilled in the art can be applied.
  • said box 100 can advantageously be used to contain articles such as, preferably, fruit (for example, oranges, lemons) and vegetables or fish products.
  • articles such as, preferably, fruit (for example, oranges, lemons) and vegetables or fish products.
  • the box 100 comprises a frame 1 having a bottom wall 2 (typically with a rectangular shape) connected to two larger lateral walls 3 and 6 and to two smaller lateral walls 4 and 5.
  • the lateral walls 3-6 connected to each other, define an upper edge 24 and, together with the bottom wall 2, define a region RI inside the box 2.
  • the frame 1 (even though it has a certain conical shape) is substantially of a parallelepiped shape and, that is, it has the lateral walls 3-6 inclined relative to a vertical axis (perpendicular to the bottom wall 2) in such a way as to have an inclination which is not inexistent but negligible and, for example, inferior to 5% or, preferably, inferior to 3%.
  • said negligible inclination also due to needs connected to molding techniques, has no disadvantages in terms of reduction of the internal volume RI of the frame available to contain the articles.
  • the smaller lateral wall 5 comprises a first blocking element associated to the upper edge 24.
  • said first blocking element is a first opening 12 (opening on a corresponding hollow region) made in the upper edge 24.
  • a second and a third opening 13 and 14 are made in the upper edge 24 of the larger wall 6 and a fourth opening 15 is made in the upper edge of the smaller lateral wall 4.
  • the box 100 is further provided with other blocking elements and made, for example, in the shape of protuberances or teeth 16, 17, 18 associated to an external face of the larger lateral wall 3 (teeth 16 and 17) and of the smaller lateral wall 4 (tooth 18).
  • a further tooth 18', associated to the smaller wall 5 and specular to the tooth 18, is visible in figure 3.
  • the tooth 16 (figure 3) of the larger lateral wall 3 but similar considerations are valid also for the other teeth), it is hook-shaped and has one end connected to the larger lateral wall 3 in a region near the bottom wall 2, and it extends downwards (i.e. towards the bottom wall) substantially parallel to the wall 3 itself.
  • Said tooth 16 has one free end 16' which, advantageously, does not protrude below the bottom wall 2. It should be observed that the blocking elements, including the openings 12-15 and the teeth 16-18 and 18', are substantially configured in such a way as not to occupy the internal region RI and they develop externally to the box.
  • each of these teeth 16-18 and 18' is intended to be inserted into openings identical to the openings 12-15 present in another box (identical to the box 100) to be placed under box 100.
  • At least two opposite lateral walls of the box 100 have a respective tooth and respective opening aligned in a direction parallel to the longitudinal axis of the box.
  • the larger lateral walls 3 and 6 have a tooth 16 and the second opening 13 aligned in a direction parallel to the transversal axis.
  • the smaller lateral walls 5 and 4 are respectively provided with a first sliding guide 40 and a second sliding guide 50 and the larger lateral wall 3 is provided with further sliding guides 60 and 70, substantially identical to each other.
  • the larger lateral wall 6 is not provided with sliding guides.
  • this guide includes a hollow region 22 in the same lateral wall which faces a corresponding opening in the internal region RI.
  • the hollow region 22 is such as to house the similar ribbing of the guide of another box intended to be inserted into the box 100 and the ribbing 10 is such as to be inserted into a hollow region of a further box into which the box 100 is to be inserted.
  • the ribbing 10 goes from an upper region of the larger lateral wall near the edge 24 towards a lower region near the bottom wall 2 and, for example, is such as to give the hollow region 22 a truncated cone cross-section.
  • the other guides 40, 50, 70 include hollow regions 20, 21, 19 and ribbing 8, 9, 7 respectively, being identical to the guide 60.
  • Each of the guides 40, 50, 60 and 70 is such as to couple mechanically with a guide (placed in the same position) which another box is provided with (of the same type as box 100, that is, substantially identical to it) in such a way as to enable reciprocal sliding of the boxes so that one box is inserted into the other.
  • the ribbing of each guide 40-70 has the advantage of providing greater mechanical resistance to the frame 1 of the box 100.
  • the teeth 16, 17, 18, 18' described above are arranged in such a way that they are substantially aligned vertically with the guides 70, 40, 50 and 60 respectively.
  • each tooth is aligned with a guide in a vertical direction parallel to the vertical axis at right angles to the bottom wall 2.
  • tooth 16 this is anchored to the external face of the larger lateral wall 3 and to an inferior portion (i.e. near the bottom) of the guide 70, so being aligned to it.
  • a guide with relative tooth for example the guide 70 and the tooth 16, made in a lateral wall (such as the larger lateral wall 3) facing another wall (wall 6) without guides which are aligned with the above-mentioned guide (i.e., according to the embodiment, guide 70) in a direction perpendicular to the two facing walls.
  • the box 100 there are at least two guides with relative teeth not in line with the axis or axes perpendicular to the relative lateral walls (the guide 70 and the guide 60 are not in line with guide 50).
  • the box 100 there is at least one opening, for example the opening 13, made in a lateral wall (such as the larger lateral wall 6) facing another wall (wall 3) without openings which are aligned with the above-mentioned opening (i.e., according to the embodiment, opening 13) in a direction perpendicular to the two facing walls.
  • the box 100 there are at least two openings not aligned with the axis or axes perpendicular to the relative lateral walls (the opening 13 and the opening 14 are not aligned with the opening 12).
  • the box 100 is also provided with handle-openings 31 made in the smaller lateral walls to enable grasping of the box itself and with window openings 32 made in several regions of the frame 1 through which it is possible to observe, from the outside, the goods present inside the box and which consent reduction in the material used for manufacture without compromising the mechanical performance of the frame 1.
  • Figure 5 illustrates another box 200 on which it is possible to stack the box 100 and into which said box can be inserted, or vice-versa.
  • the box 200 is of the same type as the above-described box 100 and the structural elements similar to those of box 100 are indicated in figure 5 with the same numerical references followed by the letter "I".
  • the box 100 and the further box 200 can take on two reciprocal configurations: one inserting configuration and another configuration where they are stacked, i.e. placed one on top of the other.
  • FIG. 1 To insert box 100 into the other box 200 (empty), reference should be made to figures 1 and 5.
  • the box 100 is placed on top of box 200 in such a way that the guides 40, 50, 60 and 70 are aligned with guides 40I, 50I, 60I and 70I respectively.
  • the ribbing 7, 8, 9 and 10 of the guides of the top box 100 slide into the hollow regions 19I, 20I, 21I and 22I of the bottom box 200 in such a way that the top box 100 is at least partially inserted into the internal region RI-I of the bottom box 200.
  • the teeth 16-18 and 18' are mechanically uncoupled from the openings 12I-15I, since they are not aligned and superimposed on them.
  • top box is inserted into the bottom box for a value greater than 70% of its volume and, for example, equal to 80% of its volume.
  • the box 100 In order to obtain the stacking configuration, the box 100 must be turned 180° relative to the inserting configuration and placed on top of box 200. In this case, the teeth 16, 17, 18 and 18' of the box 100 are inserted into the openings 14I, 13I, 12I and 15I of the box 200 respectively. In this stacking configuration, the bottom 2 of the box 100 is placed on the edge 24I of the box 200 and the teeth 16, 17, 18 and 18' make it possible to block any undesired insertion of the box 100 into the box 200 due to the weight of the top box and, advantageously, they impede reciprocal horizontal sliding of the two superimposed boxes. In the stacking configuration, the sliding guides 40-70 are mechanically uncoupled from the sliding guides 40I-70I, since they are not aligned and superimposed on them.
  • the ribbing associated to the guides 40, 50, 60, 70 provides considerable mechanical resistance which enables stacking several full boxes. For example, up to fifteen boxes made in plastic material can be stacked, having a weight of 350 g each and each containing goods for a weight equal to approximately 5 kg.
  • figure 6 shows a plan of a box 300 which has a different arrangement of guides and openings from that illustrated until now.
  • the guides 40V, 50V, 60V and 70V are arranged in couples and distanced on the two larger lateral walls and they each face a respective opening 12V-15V made in the opposite lateral wall.
  • the box according to the invention can be produced with other suitable blocking means, different from the above-described teeth and openings.
  • suitable blocking means different from the above-described teeth and openings.
  • slightly protruding horizontal flaps can be used and, instead of openings, cavities can be made in the edge to house said flaps or, alternatively, teeth or other projections can be made on the upper edge 24 of the box to engage with openings made in the side edge of the bottom wall of the top box.
  • sliding means can be used of a type different from the one illustrated, for example, projecting tongues and corresponding grooves.
  • box 100 is used to contain fruit and vegetables, some examples of dimensions are: 40 cm by 30 cm by 16 cm; 40 cm by 30 cm by 18 cm; 50 cm by 30 cm by 16 cm ; 50 cm by 30 cm by 13 cm.
  • the teachings of the present invention are particularly advantageous. In fact, it is possible to insert the boxes into each other quickly and easily (reducing considerably the total volume occupied by a plurality of empty boxes) without having to reduce the volume of the internal region of the box, contrary to what would happen in the case of boxes with a clearly conical shape.
  • the volume occupied by approximately 3900 fruit boxes of the same size and produced according to the known art is occupied by approximately 18000 boxes which can inserted one into another and produced according to the invention.
  • the teachings of the invention make it possible to insert one box into another without reducing the total volume available for the goods compared to that of the boxes known in the art and, therefore, to use the box according to the invention in those markets (such as the fruit and vegetable market) where the dimensions (and, therefore, the quantity of goods therein contained) are established by standards laid down by law or by deep-rooted habit.
