    DESCRIPTION
    COVER FOR ONE OR MORE PRODUCTS AVAILABLE ON A PALE Field of technology
    The present invention concerns in general a cover to protect one or more products arranged in a pale from environmental conditions, and more particularly a cover that when not in use is stackable on other analog covers and that when this use is stackable together with the pale and the products arranged in it on other analog covers placed covering products arranged in respective pales.
    Background of the invention
    It is known to have one or more products on a pale provided with transverse channels configured to receive a fork of a forklift, so that the products arranged on the corresponding pale form a load unit that can be stored and that can be handled and transported by the forklift.
    It is also known to stack several such loading units formed by the products and their corresponding pallets on each other for storage when the products arranged on the pallets have a suitable shape and strength. Often, when the products arranged on the pallets have good weather resistance or are packaged in containers that have good weather resistance, the storage of the loading units is carried out in outdoor camps.
    By way of example, in the field of the food industry it is known to store flexible bags filled with a flowing or pasty material, such as for example crushed fruit pulp or a fruit concentrate, within a tightly sealed metal drums that are arranged, for example in groups of two or four, on pales. The loading units formed by the groups of metal drums and corresponding shovels are stored in outdoor camps in piles of up to four levels or more, where the pale of a loading unit rests on the upper surface of the metal drums of another unit of load located in a lower level. Metal drums protect flexible bags filled with flowing or pasty material against atmospheric agents and resist the weight of other cargo units stacked on them.
    Since metal drums have a relatively high cost, when flexible bags filled with flowing or pasty material must be shipped, flexible bags

    filled with flowing or pasty material are transferred from the metal drums to disposable containers made of corrugated cardboard that are conveniently sent on pallets to the recipient, and the recipient, once the flexible bags have been removed, can send the disposable containers to be recycled. This avoids the need for the recipient to store and return empty metal drums.
    However, the task of transferring the flexible bags filled with flowing or pasty material from the metal drums to the disposable containers is difficult to perform manually and difficult to machine, taking into account that the metal drums used have a capacity of around 220 liters, and that the corresponding flexible bags, which can contain up to 200 kg or more of flowing or pasty material, are difficult to grasp and handle. In addition, there is a risk that during the transfer process microcracks or breakages occur in the flexible bags that can spoil the product contained therein.
    On the other hand, if, in order to avoid transfer tasks, flexible bags filled with flowing or pasty material were placed directly in the disposable containers and disposable containers arranged on pales were stored in an outdoor field, it would occur that the containers Disposable made of corrugated cardboard will not be useful since they have a very bad weather resistance, especially against atmospheric agents such as rain, and may be too weak to support the weight of other cargo units stacked on them.
    Document FR 2898878 A1 discloses a cover for one or more products arranged in a pale. This cover comprises a structure that includes a plurality of pillars having upper ends joined to a roof panel and lower ends supported on the pale by support elements, and a wrap-around side enclosure consisting of a flexible canvas attached to the structure closing some spaces between the pillars. A drawback of this cover is that it does not have transverse channels suitable for receiving a fork of a forklift and is not intended to be stacked with other analog covers when not in use or to support the weight of other load units stacked on it. When in use.
    Document US 2016001922 A1 describes a cover for one or more products arranged in a pale, where the cover comprises a roof panel and a wrapping side enclosure constituted by a flexible canvas provided with sleeves in which adjustable bars are inserted which constitute a structure. At the lower ends

    of some of the adjustable bars there are some support elements that are attached to the pale. However, this deck does not have transverse channels suitable for receiving a fork of a forklift and is not intended to be stacked with other analog covers when it is not in use or to support the weight of other load units stacked on it when it is in use. In use.
    Therefore, there is a need for a cover for one or more products arranged in a pale that is capable of protecting the products against atmospheric agents and against dust, which is provided with transverse channels suitable for receiving a fork of a forklift to allow handling of the deck with the forklift, which is stackable with other analog covers when not in use, and that is capable of supporting the weight of other cargo units stacked on it when in use.
    Exposition of the invention
    The present invention contributes to meet the above and other needs by providing a cover for one or more products arranged in a pale. The cover of the present invention comprises a roof panel, a structure including a plurality of pillars having upper ends attached to the roof panel and lower ends supported on the pale by support elements, and a wrap-around side enclosure attached to the structure closing some spaces between the pillars. The cover of the present invention further comprises transverse channels formed between the ceiling panel and one or more upper plate elements joined to the ceiling panel by separating elements.
    Throughout this description, the terms "superior", "inferior", "above", "below" and their derivatives and equivalents are defined in relation to a normal position of use of the roof.
    Said transverse channels are arranged above the roof panel and serve to receive a fork of a forklift, for which they are conveniently sized. Thus, by means of the transverse channels, the cover can be handled by a forklift to place it covering the products arranged in the pale, to remove it from the pale, to transport it, and to stack it with other analog covers when the cover is not in use. The one or more upper plate elements may comprise a single upper plate element fixed to all the separator elements or several upper plate elements fixed as a bridge between two or more separator elements.

    The roof panel and the enclosing side enclosure are made of a material resistant to atmospheric agents. Thus, when the cover is placed covering the products arranged on the pale, the cover protects the products against atmospheric agents and against dust.
    The pale together with the products arranged on it constitutes a loading unit. As is conventional, the pale also has transverse channels to receive the forklift of the forklift, so that the forklift can use the transverse channels of the pale to lift, transport and handle the load unit together with the cover arranged covering the products. Optionally, the forklift can place the loading unit on a deck associated with another loading unit, since the pillars of the deck resist the weight of up to three or more load units with their respective decks stacked on top of the deck.
    In a preferred embodiment, the support elements by which the pillars are supported in the pale comprise support surfaces formed at the lower ends of the pillars. Preferably, these bearing surfaces are horizontal.
    In a particular embodiment, the roof panel has a rectangular shape with four perimeter edges and the surrounding side enclosure comprises four vertical side panels that have upper edges attached to the perimeter edges of the roof panel, side edges joined together in panels adjacent sides, and free bottom edges. However, in other alternative embodiments the roof panel may be circular, oval, polygonal, rounded, or it may have straight edges and curved edges in combination, and the wrap-around side enclosure may be configured in accordance with the shape of the roof panel. Optionally, the side panels have ribs arranged forming a lattice to increase the rigidity of the side panels.
    The pillars are arranged in suitable positions so as not to interfere with the products arranged on the pale. In the embodiment in which the roof panel has a rectangular shape and the surrounding side enclosure comprises four side panels, the pillars preferably include four corner pillars located in the four inner corners formed by the four side panels. Optionally, the pillars can also comprise intermediate pillars located in intermediate lateral positions between the corner pillars and / or a central pillar located in a central position with respect to the roof panel.

    In this same embodiment, the separator elements preferably comprise four corner separator elements located in the four corners of the ceiling panel. Optionally, the separating elements may further comprise intermediate separating elements located in intermediate lateral positions between the corner separating elements and / or a central separating element located in a central position with respect to the ceiling panel.
    Preferably, the free bottom edges of the side panels define a slightly larger contour than a perimeter edge of an upper surface of the pale, and the support surfaces of the pillars are located on the same first level while the free bottom edges of the panels laterals are located at a second level lower than the first level, so that there is a predetermined distance in a vertical direction between the first level and the second level. Thus, when the abutment surfaces of the pillars are supported on the upper surface of the pale, the free lower edges of the side panels are located below the level of the upper surface of the pale and lower portions of the lateral panels form a skirt perimeter that protects an interstitium between the side panels and the upper surface of the pale against atmospheric agents and dust.
    In addition, the corner separating elements, and preferably also the intermediate separating elements, if any, have vertical lower outer surfaces adjacent to the roof panel and vertical upper outer surfaces adjacent to the upper plate element, and these lower outer surfaces and upper outer surfaces are separated by a horizontal step, so that the lower outer surfaces define a lower perimeter equivalent to an outer perimeter of the side panels and the upper outer surfaces define a higher perimeter smaller than an inner perimeter of the side panels. The step has a height equivalent to the distance between the first level and the second level, and the upper plate element does not protrude laterally from the upper outer surfaces.
    Thus, the cover can be stacked on another analog cover so that the support surfaces of the roof pillars located at a higher level rest on the upper surface of the upper plate element of the cover located at a lower level and the Perimeter skirt formed by the lower portions of the side panels of the roof located on an upper level fit into the step of the roof located on a lower level. Stacking of several covers when they are not in use can
    5
    10

    be easily carried out by a forklift using the transverse channels of the roofs.
    In a preferred embodiment, the cover comprises two or more bodies obtained by injection molding of a plastic material, such as HDPE high density polyethylene, although these two or more bodies admit multiple embodiments. The two or more bodies are preferably joined together by mutual engagement of respective complementary male / female coupling elements, although optionally or additionally they may be joined by other joining means, such as adhesive, thermo-welding, screws or rivets.
    For example, in a specific embodiment including bodies of injected plastic material, the roof panel, the four side panels and lower portions of the separating elements are integrated into a first body made of the injected plastic material, and the upper plate element and upper portions of the separator elements are integrated in a second body made of the injected plastic material. Preferably, the lower portions of the separating elements have upper openings in which the upper portions of the separating elements are partially fitted.
    In another specific embodiment including bodies of injected plastic material, the four side panels and first complementary separator elements are integrated in a first body made of said injected plastic material, the ceiling panel 1 and the separator elements are integrated in a second body made of the injected plastic material, and the upper plate element and a few second complementary separating elements are integrated in a third body made of the injected plastic material.
    In yet another specific embodiment including bodies of injected plastic material, the four side panels and the separating elements are integrated in a first body made of said injected plastic material, the roof panel is divided into two halves and each of these two halves of the roof panel and corresponding first complementary separating elements are integrated in two respective second bodies made of the injected plastic material, and the upper plate element and a second complementary separating elements are integrated in a third body made of the injected plastic material.
    In any of these embodiments including bodies of injected plastic material, one or more of the pillars may be integrated in the first body made of the plastic material

    injected, in which case the pillars can be hollow to reduce the amount of plastic material necessary for its realization. Alternatively or additionally, in any of the embodiments including bodies of injected plastic material, one or more of the pillars may be constituted by separate pieces fixed to one or more of the first, second and third bodies made of the injected plastic material, for example by adhesive, by thermo-welding, by male / female coupling, or by mechanical joining elements such as screws or rivets. These separate pieces that form the pillars can be solid or hollow and can be made of any suitable material, such as for example wood, a plastic, or a metal, preferably a light metal alloy, such as an aluminum alloy.
    Optionally, from one or more of the support surfaces of the pillars, a small spike that sticks into the upper surface of the pale protrudes downwards due to the weight of the roof itself. This contributes to the fact that the cover does not move laterally with respect to the pale, for example during the transport of loading units including the cover arranged covering the products. In one embodiment, the barb is part of a metal piece embedded at least in part on the supporting surface of the corresponding pillar.
    In an alternative embodiment, the enclosing side enclosure of the cover comprises one or more flexible canvases joined to an outer side of the structure by a releasable fastening device, such as for example a hook and loop fastening device of the type marketed under the VELCRO registered trademark. These one or more flexible canvases are preferably also attached to the perimeter edges of the roof panel, either by substantially permanent fasteners, such as for example tacks, nails, screws, rivets or adhesive, or by a releasable fastening device. , such as a hook and loop fastener.

    Detailed description of some examples of realization
    First, reference is made to Figs. 1 to 11, wherein the reference sign 30 generally designates a cover according to an embodiment of the present invention, which is configured to cover one or more products arranged in a pale 50.
    In the example illustrated in Figs. 1 and 9 to 11, the products arranged on the pale 50 are four containers 51 which generally have an octagonal prismatic shape and which are attached to the pale 50 by straps or straps 52. In this example, the containers 51 are disposable containers made of corrugated cardboard, each of which contains a flexible bag filled with a flowing or pasty material, such as
    5

    crushed fruit pulp. The pale 50 is of a conventional type that includes transverse channels 53 sized to receive the fork of a forklift (not shown). The containers 51 and the pale 50 together form a loading unit, so that the forklift can lift, transport and handle the loading unit using the transverse channels 53 of the pale 50.
    The cover 30 comprises a roof panel 1, a wrap-around side enclosure formed by side panels 2, and a structure including a plurality of pillars 7, 8, 9 attached to the side panels 2. The pillars 7, 8, 9 also have upper ends attached to the roof panel 1 and lower ends provided with support surfaces 7a, 8a, 9a which constitute support elements provided to rest on an upper surface of the pale 50.
    The roof panel 1 has a rectangular shape with four perimeter edges 1a and the surrounding side enclosure comprises four of said side panels 2 arranged in a vertical position. The side panels 2 have upper edges attached to the perimeter edges 1a of the roof panel 1, side edges 2a joined together in adjacent side panels 2, and horizontal free bottom edges 2b all located on the same level. Thus, the enclosing side enclosure closes existing spaces between the pillars 7, 8, 9. The side panels 2 have ribs 13 arranged in a lattice.
    Above the roof panel 1 there is an upper plate element 6 which is connected to the ceiling panel 1 by separating elements 3, 4, 5, and channels are formed between the ceiling panel 1 and the upper plate element 6 crossbars 12 sized to receive the forklift of the forklift. Thus, the forklift can lift, transport and handle the deck 30 using the transverse channels 12 of the deck. In the embodiment shown, the upper plate element 6 is fixed to all the separating elements 3, 4, 5 and is provided with openings, although alternatively there could be a plurality of upper plate elements fixed as a bridge between two or more of the separating elements 3, 4, 5.
    In the illustrated example, in which the cover 30 is adapted to cover groups of two or four containers 51 in an octagonal prismatic shape arranged on pallets 50, the pillars 7, 8, 9 include four corner pillars 7 located in four interior corners formed by the four side panels 2, four intermediate pillars 8 located in
    5
    10
    fifteen
    twenty
    25
    30
    intermediate lateral positions between the corner pillars 7, and a central pillar 9 located in a central position with respect to the roof panel 1.
    The corner pillars 7 have a rectangular section in the form of a rectangular triangle preferably isosceles with their legs parallel to the side panels 2 and their hypotenuse facing the inside of the cover 30, the intermediate pillars 8 have a cross section in the form of a rectangular triangle preferably isosceles with its hypotenuse parallel to the corresponding side panel 2 and its legs facing the inside of the cover 30, and the central pillar 9 has a square cross-section with its diagonals parallel to the side panels 2. Alternatively, the central pillar 9 could have a cross section of any other polygonal or circular shape. Alternatively, the pillars 7, 8, 9 could have other forms of cross section adapted to other types of load units.
    The separating elements 3, 4, 5 comprise four corner separating elements 3 located in four corners of the roof panel 1, four intermediate separating elements 4 located in intermediate lateral positions between the corner separating elements 3, and a central separating element 5 located in a central position with respect to the roof panel 1.
    As shown in Figs. 3, 7 and 8, the support surfaces 7a, 8a, 9a of the pillars 7, 8, 9 are all located on a first level and the lower free edges 2b of the side panels 2 are all located on a second level below the first level, so that between the first level and the second level there is a distance D in a vertical direction.
    On the other hand, as Fig. 2 best shows, the corner separating elements 3 and the intermediate separating elements 4 have respective lower outer surfaces 3a, 4a adjacent to the ceiling panel 1 and respective upper outer surfaces 3b, 4b vertical adjacent to the upper plate element 6, and these lower outer surfaces 3a, 4a and upper outer surfaces 3b, 4b are separated by horizontal steps 10, 11.
    The lower outer surfaces 3a, 4a of the corner and intermediate separator elements 3, 4 define in a horizontal plane a lower perimeter that is equivalent to an outer perimeter of the side panels 2. The upper outer surfaces 3b, 4b of the separator elements corner and intermediate 3, 4 define in a horizontal plane an upper perimeter that is smaller than an inner perimeter of the side panels 2. The
    5
    10

    30
    Steps 10, 11 have a height equivalent to the distance D between the first level and the second level. The upper plate element 6 does not project laterally from the upper outer surfaces 3b, 4b of the corner and intermediate separator elements 3, 4.
    The cover 30 according to the embodiment shown in Figs. 1 to 11 comprises two bodies obtained by injection molding of a plastic material. More specifically, and as shown in Fig. 4, the cover 30 comprises a first body 30a made of the injected plastic material in which the roof panel 1, the four side panels 2 and lower portions 33a, 34a, 35a are integrated of the separating elements 3, 4, 5, and a second body 30b made of the injected plastic material in which the upper plate element 6 and upper portions 33b, 34b, 35b of the separating elements 3, 4, 5 are integrated. The injected plastic material is, for example, HDPE high density polyethylene.
    The lower portions 33a, 34a, 35a of the separating elements 3, 4, 5 have upper openings in which the upper portions 33b, 34b, 35b of the separating elements 3, 4, 5 partially fit forming a male / female coupling . The lower portions 33a, 34a of the corner and intermediate separating elements 3, 4 define the aforementioned lower outer surfaces 3a, 4a (Fig. 2) and the upper portions 33b, 34b of the corner and intermediate separating elements 3, 4 define said upper outer surfaces 3b, 4b (Fig. 2).
    In this embodiment, the pillars 7, 8, 9 are constituted by separate pieces fixed to the first body 30a. for example by adhesive, by thermo-welding, by male / female coupling, by screws or by rivets, although they may alternatively be integrated in the first body 30a. As shown in Fig. 3, metal parts 14 are embedded in the lower ends of the pillars 7, 8, 9 that have spikes 14a protruding downward from the supporting surfaces 7a, 8a, 9a.
    Fig. 8 shows two decks 30 according to this embodiment stacked on one another, where the supporting surfaces 7a, 8a, 9a of the pillars 7, 8, 9 of the deck 30 located at the upper level rest on a surface upper of the upper plate element 6 of the cover 30 located on the lower level, and where a perimeter skirt constituted by lower portions of the side panels 2 of the cover 30 located on the upper level fit into the steps 10, 11 formed in the separating elements 3, 4 of the cover 30 located on the lower level.
    Figs. 9 and 10 show a cover 30 according to this embodiment arranged covering products arranged on a pale 50, where the products are, by
    5
    10

    25
    30
    For example, four octagonal prismatic disposable containers 51 made of corrugated cardboard, analogous to those described above in relation to Fig. 1. Fig. 10 shows how the pillars 7, 8, 9 are configured and arranged on purpose so as not to interfere with the containers 51 arranged on the pale 50.
    Fig. 11 shows a cover 30 according to this embodiment arranged covering products arranged on a pale 50, which in turn is stacked on another cover 30 according to this embodiment arranged covering products arranged on another pale 50. Also in this case the products are, for example, four disposable containers 51 in octagonal prismatic form made of corrugated cardboard containing flexible bags filled with a flowing or pasty material, analogous to those described above in relation to Fig. 1.
    The bearing surfaces 7a, 8a, 9a of the pillars 7, 8, 9 of both decks 30 rest on an upper surface of their respective paddles 50, and the prongs 14a are driven into the upper surfaces of the paddles 50 by effect of weight of the covers 30 and the loading unit located on the upper level. The pale 50 located on the lower level rests on the ground and the pale 50 located on the upper level rests on an upper surface of the upper plate element 6 of the cover 30 located on the lower level, so that the pillars 7 8, 9 of the deck 30 located on the lower level transmit the weight of the loading unit and the deck 30 located on the upper level directly to the pale 50 of the loading unit located on the lower level and to the ground, without affect the containers 50 arranged on the pale 50 located on the lower level.
    The covers 50 protect the containers 51 arranged on the respective pallets 50 against atmospheric agents and dust. The perimeter skirts constituted by the lower portions of the side panels 2 of the covers 30 extend outwardly and downwards from the upper surfaces of the respective pales 50 preventing or hindering the entry of water and dust through an interstitium between the panels lateral 2 and the upper surfaces of the pales 50.
    Since in the illustrated example the containers 51 are made of corrugated cardboard, the covers 30 allow the containers 51 arranged on pallets to be stored in outdoor camps for long periods of time without risk of the containers 51 being degraded due to the atmospheric agents and environmental conditions, and avoids the need to initially store flexible bags filled with flowing or pasty material in metal drums for outdoor storage and storage.

    subsequently transfer the flexible bags filled with flowing or pasty material from the metal drums to the disposable containers 51 for expedition to a recipient.
    However, the cover 30 of the present invention is not limited to the protection of octagonal prismatic containers 51 made of corrugated cardboard and can be used and adapted for the protection of any other type of products arranged on pallets. In any case, the configuration and dimensions of the roof panel 1 and of the side panels 2 or other enclosing side enclosure will be adapted to the type of pale 50 used, and the number, configuration and position of the pillars 7, 8, 9 will be adapted to the characteristics of the products arranged on the pales 50.
    Fig. 12 illustrates another embodiment of the cover 30 of the present invention, wherein the cover 30 comprises three bodies 31a, 31b, 31c obtained by injection molding of a plastic material, such as HDPE high density polyethylene. Thus, in the embodiment of Fig. 12, the four side panels 2 and first complementary separating elements 37, 38, 39 are integrated in a first body 31a made of the injected plastic material, the roof panel 1 and the separating elements 3 , 4, 5 are integrated in a second body 31b made of the injected plastic material, and the upper plate element 6 and a second complementary separator elements 37a, 38a are integrated in a third body 31c made of the injected plastic material. The first complementary separating elements 37, 38, 39 and the second complementary separating elements 37a, 38a complement the separating elements 3, 4, 5.
    The first, second and third bodies 31a, 31b, 31c have respective complementary male / female coupling elements that engage each other to fix the first, second and third bodies 31a, 31b, 31c, although alternatively the fixation of the first, second and third bodies 31a, 31b, 31c with each other can be completed or replaced by a joint by means of adhesive, thermo-welding, screws or rivets. The pillars 7, 8, 9 are preferably integrated in the first body 31a, although they can alternatively be separate pieces fixed to the first body 31a by adhesive, by heat welding, by male / female coupling, by screws or by rivets.
    Fig. 13 illustrates yet another embodiment of the cover 30 of the present invention, wherein the cover 30 comprises four bodies 32a, 32b, 32c, 32d obtained by injection molding of a plastic material, such as HDPE high density polyethylene. Thus, in the embodiment of Fig. 12, the four side panels 2 and the separator elements 3, 4
