    DESCRIPTION
    Tray for transporting products.
    The present invention relates to a tray for transporting products, in particular, which allows the stacking of several trays on each other for transport, and which is formed from a cardboard sheet.
    Background of the invention
    It is common to use cardboard trays or similar materials to transport products, such as fruits. These types of trays have the advantage that their cost is reduced and they are made of a recyclable material.
    Usually, these types of trays are formed from a sheet provided with a plurality of folding lines that define a bottom, a pair of sides and a pair of bows.
    To allow stacking for transport, these trays comprise a plurality of upper projections that are housed in complementary lower holes. However, it is usual that, despite said projections and holes, said stack is unstable, not allowing the stacking of a large number of trays.
    In addition, to allow high compression resistance, it is usual for the thickness of the sheet forming the tray to be high, which impairs the internal volume of products that the tray can accommodate.
    This problem of the internal volume of the tray is multiplied taking into account the stacking of the trays and their transport on loading platforms, which makes the transport of the products more expensive.
    Therefore, it is an objective of the tray according to the present invention to allow stable stacking of the trays, so that they do not move relative to each other during transport.
    Another objective of the tray according to the present invention is to maximize the volume available inside the tray, as compared to the transport trays of conventional products of the same size.
    Description of the invention
    With the tray for transporting products of the invention, the aforementioned drawbacks are resolved, presenting other advantages that will be described below.
    The tray for transporting products according to the present invention is formed from a sheet that defines a bottom, and a pair of sides and a pair of pockets that define four corners, comprising a plurality of protrusions and holes complementary to each other. , and is characterized in that each corner comprises at least one upper projection located in the tester and an upper projection located on one side, said upper projections extending from the inside of said tester and from said lateral.
    Advantageously, the tray for transporting products according to the present invention also comprises an additional upper projection located in the center of each tester, and extending from the inside of said tester.

    Preferably, the tray for transporting products comprises a complementary hole with each upper projection located at least in the heads, each hole comprising a tongue that extends downward from the outside of each tester associated with each hole.
    According to a preferred embodiment, said laterals and / or said testers are slightly inclined inwards.
    Although it could be of any suitable material, said sheet forming the tray according to the present invention is made of compact cardboard, for example, of compact cardboard with a thickness of approximately 1 mm.
    Advantageously, the bottom comprises a plurality of associated openings in pairs.
    With the tray for transporting products according to the present invention a perfect stacking of the trays is achieved with each other, not moving with respect to each other during transport. This is achieved thanks to the arrangement of the projections, which extend from the inside of the heads and sides.
    In addition, thanks to the use of compact cardboard of a reduced thickness, an inner volume of the upper tray is achieved than a conventional corrugated cardboard tray with the same dimensions, which implies a large reduction in transport costs.
    Brief description of the drawings
    For a better understanding of how much has been exposed, some drawings are attached in which, schematically and only by way of non-limiting example, a practical case of realization is represented.
    Figure 1 is a plan view of a corner of the sheet forming the product transport tray according to a first embodiment of the present invention;
    Figure 2 is a perspective view of a corner of the product transport tray according to a first embodiment of the present invention; Y
    Figure 3 is a perspective view of a corner of the product transport tray according to a second embodiment of the present invention.
    Description of a preferred embodiment
    First, it should be noted that two alternative embodiments of the product transport tray according to the present invention are shown in the figures. For simplicity reasons the common elements have been indicated by the same numerical references.
    A corner of the sheet forming the product transport tray according to a first embodiment of the present invention is shown in Figure 1.
    According to a preferred embodiment, said sheet 1 is made of compact cardboard, for example with a thickness of about 1 mm, although it could be of any suitable material with a suitable thickness.
    Said sheet 1 comprises a plurality of folding lines and cutting lines defining a bottom 2, two sides 3 and two heads 4 defining four corners of the tray,

    in addition to a plurality of projections and holes that will be described in detail later.
    Although it cannot be seen in Figure 2, it should be noted that the sides 3 and the ends 4 are positioned slightly inclined towards the inside of the tray, to facilitate stacking of the trays.
    As can be best seen in Figure 2, each tester 4 is formed by two flaps 4a, 4b, folding one envelope in the other in the position of use of the tray according to the present invention. In addition, each tester 4 also comprises outer side flaps 4c that are fixed on the outside of the sides 3 at each corner of the tray and inner side flaps 4d that are fixed on the outside of the sides 3 in each corner.
    It should be noted that said inner side flaps 4d are attached to the bottom of the sides 3 forming in each corner a reinforcing column, as shown in Figure 2. This reinforcing column allows to reinforce the vertical compressive strength of the product transport tray according to the present invention.
    For its part, the sides 3 comprise a central flap 3a that folds into the tray, whose side edges are preferably in contact with the side edge of the inner side flap 4d indicated above, as seen in the second embodiment of figure 3.
    In this way, a tray for the transport of products of great resistance is achieved, since at least a double thickness is achieved in the corners, which is the one that supports the weight of the trays stacked with each other, and in the part of the side of the corners, the thickness is triple.
    In order to allow stacking of the trays with each other while avoiding their relative movement during transport, each corner of the tray comprises an upper projection 5 located in the front 4 and an upper projection 6 located on the side 3. These upper projections 5, 6 are they extend from the inside of said tester 4 and said side 3, respectively.
    These upper projections 5, 6, when two trays are stacked on top of each other, are housed in complementary holes 10, 11 of the upper tray.
    According to the first embodiment, an additional central projection 7 is also provided in each tester 4, which is placed in the upper central part of said tester, as shown in Figure 2, and in the stacked position, said central projection 7 is housed in a central hole 8 of the upper tray.
    It should be noted that in the second embodiment shown in Figure 3 this additional central projection 7 is not present, this being the main difference between both embodiments.
    This central hole 8 has an associated tongue 9 which extends downwards from the outside of said tester 4, to achieve a better retention of said central projection 7.
    In the second embodiment represented in Figure 3, the holes 10 present in the heads 4 also have an associated tongue 9, which extends downwards from the outside of said head 4, to achieve a better retention of said upper projections 5.
    In addition, at the bottom 2 of the tray according to the present invention are arranged
    a plurality of openings 12 associated in pairs and distributed uniformly, as shown in Figure 3. The purpose of these openings 12 is to ensure the ventilation of containers (not shown) located in the tray, which also comprise openings of ventilation For example, this is especially suitable when transporting some type of food that requires ventilation.
    Although reference has been made to a specific embodiment of the invention, it is evident to one skilled in the art that the described product transport tray is susceptible to numerous variations and modifications, and that all the mentioned details 10 can be replaced by other technically equivalent ones, without departing from the scope of protection defined by the appended claims.
