Description

The present invention relates to an improved palette.

Most of the pallets existing today on the market for palletizing goods consist essentially of a base formed by transverse wooden slats supported by beams also made of wood. The elements are joined by nails and the assembly is carried out pneumatically or in a similar manner.

According to the invention, the pallet is made of plastic material using a mixture of polyethylene and polypropylene to form a single block or a structure which has the following advantages compared to pallets made of wood of the prior art: * The resistance obtained for the pallet is uniform in the sense that the injection system makes it possible to dose the components in order to make the resistance of the pallet uniform. In existing wooden pallets there may be wooden transverse slats which are deteriorated since wood is a "living" material with knots and veins which make it impossible to obtain uniform and continuous strength of the product.

* The pallet of the invention makes it possible to obtain a significant reduction in weight, since manufacturing by injection reduces the weight by at least half.

* The injection avoids the disadvantages due to occasional bursts and the presence of nail heads which appear in conventional pallets and scratch the products stored on the pallets, which can also be the cause of accidents for the operators who handle them.

* The thickness of the surface of the support of the pallet of the invention can vary so as to confer an I

greater resistance to pallets depending on the load to be palletized, so that light loads or goods can be palletized with thin pallets, while larger loads will be palletized on thick pallets or heavier weights. During the injection also, a reinforcement system can be added using for example glass fiber which will undoubtedly increase the resistance.

* The continuous surface of the pallet can be treated in a rough or grainy way so that the merchandise which it supports does not slip and it can also present perforations, distributed evenly or not, so as to reduce the weight or lower the manufacturing cost.

* The manufacturing system allows cleaning and washing with soaps and detergents and also brushing if necessary, which is difficult with commonly known wooden pallets that water can deteriorate, swell or deform. The pallet of the invention can be stored outside without providing any type of additional protection.

* Unlike known wooden pallets, the pallets of the invention may have the advantage of being marked with the user's emblem or logo, either with paint, taking into account the large surface of the new palette, either molding and indelibly at the time of injection.

* The blends of polypropylene and polyethylene and certain additives to these blends make the pallets non-flammable, which constitutes an important advantage from the point of view of safety compared to the wooden pallets currently on the market.

* The resistance to humidity and impact facilitates the handling of the pallets, and they are also hygienic and well ventilated with a minimum and constant weight, and they can be made in any color.

In addition, the pallet of the invention may have a thickness, dimensions and additional details which may vary depending on the use, the loads to be palletized, the pallet being in one piece, manufactured by injection with the advantages indicated above. .

According to the invention, the pallet is constituted by a monobloc body, made of plastic material essentially consisting of a mixture of polyethylene and polypropylene.

The pallet preferably has a quadrangular surface and one of its faces carries, projecting, prismatic elements directed transversely, perpendicular to its surface and parallel to each other, these prismatic elements being arranged at the ends and in the central part, defining complementary grooves for the forks of lifting machines of this type.

In order to better understand not only the manufacture but also the utility and the use of the palette of the invention, reference will be made below to a practical example of manufacture, this example being only illustrative and in no way limiting. In the drawings: Figure 1 shows a perspective view of a pallet according to the invention; Figure 2 shows a front view of the upper face;

Figure 3 shows a side view of the pallet.

With reference to the drawings, a palette of the invention has been referenced in 1.

The pallet 1 is formed of a single body 2 having a quadrangular part 3 of reduced height.

One of the sides constituting the lower face of the pallet, referenced 4, comprises certain projecting prismatic parts referenced 5 and 6.

The parts 5 are situated at the ends and the part 6 is placed in the center so that between each of two consecutive parts spaces 7 are defined.

The upper face 8 of the quadrangular part 3 constitutes the support surface for the load.

Of course, many variants and modifications in the form and construction of the elements described above can be added without departing from the scope of the invention.

Claims (2)

1. Improved pallet characterized in that it is constituted by a single body (1) formed in a single piece molded in plastic material essentially in a mixture of polyethylene and polypropylene, having a flat quadrangular part (8) of reduced height on a face of which protrude a series of prismatic elements parallel to each other (5, 6) between which are defined spaces (7) for the introduction of mechanical elements making it possible to lift the load placed on the upper face of the body. 2. Pallet according to claim 1 characterized in that the upper quadrangular flat face has on its surface perforations, roughness and / or granulation.
