Definitions
- the present invention relates to plastic pallets of the type used for the loading and transport of goods, and in particular, it refers to the pallets called by their term in English pallets.
- the pallet described in said document allows said pallets to be assembled one on top of the other, without any problem, in addition to allowing injecting foam into special areas located near the columns of the pallets in question.
- the invention described in the Swistak document has the disadvantage of using thermofixed foam material which does not allow said pallet to be fully recycled, in addition to being a high cost product.
- thermoplastic member or pallet which can be made for example of polypropylene (PP) or high density polyethylene (HDPE), having spaces in some areas of the pallet such as the columns, which is filled with thermofix polymer foam such as polyurethane, low density polyurethane foam, ceramic, glass or an expandable mineral foam, said foam also having a fire retardant whose characteristic is additional in This plastic pallet.
- PP polypropylene
- HDPE high density polyethylene
- thermofix polymer foam such as polyurethane, low density polyurethane foam, ceramic, glass or an expandable mineral foam
- the disadvantage of this product described by Moore et al. is that the production of this type of pallet when using a thermofix polymer foam is consequently more expensive and has a longer production time, and as is known this type of plastics are hardly recyclable.
- Swistak describes a platform of the type described by Moore, which also includes holes for the injection of foam selectively placed on the lower surfaces of the columns of the platform. Plugs are used to seal the foam filling holes and vents. In a further embodiment, the plugs that protrude from the surface of the platform are coupled to grooves in the lid of a second platform, to prevent the movement of stacked platforms.
- US Patent 5,417,167 discloses a plastic platform formed of hollow plastic stringers and boards of plastic materials that can be any plastic virgin, recycled plastics or mixtures, and are formed by blow molding.
- the stringers and deck boards are hollow but have closed ends to prevent the entry of dirt, liquids and insects.
- Several alternatives of coupling between parts are described, including the fixing by the screws, as well as connections that couple the plastic pieces together and the use of components that separately couple the board and the stringers.
- a similar technique is described in US Patent 6,976,437 (Fisch et al, 2005).
- the platform of the present invention refers to a platform or "pallet” formed of a plastic material, preferably a thermoplastic selected from the group of polyolefins that includes low density polyethylene (PELD), polyethylene High density (PEHD), polypropylene (PP) and mixtures thereof.
- a thermoplastic selected from the group of polyolefins that includes low density polyethylene (PELD), polyethylene High density (PEHD), polypropylene (PP) and mixtures thereof.
- the plastic platform of the present invention is formed by two structures: a base and a cover, attachable to each other, to form a body that offers an upper surface to support the objects to be moved, a lower surface on which the body rests.
- the platform and at least 4 peripheral columns and a central column, preferably 8 peripheral columns and a central column, arranged between the upper and lower surfaces.
- the base structure includes at least four peripheral posts and a central post, the structure of the roof being provided with posts corresponding to each of the posts of the base, so that in the coupled position each post of the base will be coupled to the corresponding roof post in location, forming thus the peripheral and central columns.
- the base structure when the base structure is coupled with the roof structure, they will provide in each peripheral and central column an outer wall and an inner wall separated by a space in which a filling of foamed thermoplastic material of the group of polyolefins is included which includes to low density polyethylene (PELD), high density polyethylene (PEHD), polypropylene (PP) and mixtures thereof.
- a filling of foamed thermoplastic material of the group of polyolefins is included which includes to low density polyethylene (PELD), high density polyethylene (PEHD), polypropylene (PP) and mixtures thereof.
- the function of the filling of foamed material is to strengthen said columns, to increase the load capacity, as well as to cushion the impacts exerted on the plastic pallet during daily use, without an increase in consideration of the total weight of said plastic pallet.
- said foamed padding also provides a secure hold of the joints between the posts that form the peripheral columns, in this way movement by the game that exists between the base and the cover is prevented and provides greater support between them, avoiding thus the disassembly of the platform during its use.
- the peripheral posts of the cover include securing means in the form of hooks, which correspond to fastening means in the peripheral posts of the base, and which hold the cover and the base together once they are coupled together to form the body of the peripheral and central columns of said plastic platform.
- a foamed filler material is provided, preferably from the group of polyolefins that includes low density polyethylene (PELD), polyethylene High density (PEHD) 1 polypropylene (PP) and mixtures thereof.
- PELD low density polyethylene
- PEHD polyethylene High density 1 polypropylene
- the platform allows proper operation with the automatic forklift or with manual skid, being able to support, load and move loads greater than 1700 Kg., With a very intense movement in the storage and distribution warehouses. It must be taken into account that the handling of the plastic pallet with the loading of merchandise to the trucks is carried out at a relatively high speed, which causes the plastic pallet to be constantly impacted with the nails of said forklifts.
- the proposed design reduces the effect of said impacts on the integrity of the plastic flooring, thereby increasing its useful life and decreasing the need for frequent replacement.
- edges can be provided that give it a characteristic that prevents the sliding of the load elements placed on said platform during its transport.
- the invention provides a platform with a body formed by at least two assembled and molded plastic structures that form a base and a cover such that a space is provided within the columns in which it has a padding of foamed thermoplastic material;
- the material for the filling like that of the base and the cover, is selected from the family of polyolefins (low density polyethylene, high density polyethylene, polypropylene and mixtures thereof); being preferably the same in all the components, with which at the end of the shelf life of the platform, which will be longer than that of conventional pallets, it can be redoubled in its entirety without the need for a separation of materials.

- the invention that includes the injection of material for the reinforcement of the sides of the platform and the formation of non-skid zones.
- the present invention relates to an improved plastic pallet or platform molded from a thermoplastic material, preferably selected from the group of polyolefins which includes among others the low density polyethylene (PELD), high density polyethylene (PEHD), polypropylene (PP) and mixtures thereof.
- a thermoplastic material preferably selected from the group of polyolefins which includes among others the low density polyethylene (PELD), high density polyethylene (PEHD), polypropylene (PP) and mixtures thereof.
- the body of the plastic platform 100 of the invention is formed by two molded structures that constitute a base 200 and a cover 300 that are assembled together, to form a body 100 that offers a surface 110 to support the objects to be moved, said surface (110) preferably offering perforations that pass through it, to allow the draining of spilled liquids on said surface, for washing and to lighten the structure and a plurality of lateral holes 120 to allow the passage of the "nails" of load of forklifts, for the transfer of the plastic pallets and the objects deposited on her.
- the corners of the platform 100 of the invention are rounded.
- the base 200 includes at least 4 posts 210 located in the corners, although the preferred embodiment includes 8 posts 210, located in the corners of the body and in the middle area of the sides of the base 200, and a central pole 220 located in the center of base 200, as illustrated in Figure 2.
- the outer surfaces of posts 210 and 220 will conform
- peripheral posts 210 of the base 200 correspond to as many peripheral posts 310 formed in the cover 300, which are illustrated in Figure 3, projecting from the lower surface of the cover 300 in
- all peripheral posts 310 of the cover 300 include securing means 330 in the form of hooks, which hold the cover 300 and the base 200 together once they are coupled together to form the body of The plastic platform 100, as schematically illustrated in Figure 5.
- the posts 210 include fastening means 230 that cooperate with the securing means 330 in the form of hooks projecting from the walls of the posts 310 of the deck 300 by which both parts are engaged during the assembly of the plastic platform, as illustrated in the detail of the sectional view of Figure 5.
- peripheral projections 210 and 310 have cover 300 and base 200, there being at least four columns, one in each corner, and preferably eight columns, one in each corner and one more in the middle of each side of the platform.
- the outer wall corresponds to that of the peripheral posts 210 of the base, and the wall of the peripheral posts 310 of the roof, which are located inside the peripheral posts 210, constitute the inner wall of a recess 340 ( Figure 8) in which, according to the present invention, a foamed filler material is provided, preferably a thermoplastic of the same nature as the manufacturing material of the body of the plastic pallet 100, that is, PELD, PEHD, PP or mixtures thereof.
- each column has a height determined by the height of the peripheral post 210 and the height of the edge of the cover 300 that is resting on a flange 212 located at the periphery of the upper, open end of the post 210, so that the forces applied on the surface of the deck 300 of the platform 100 once assembled, are transmitted directly to the walls of the peripheral posts 210, and from there to the contact points between the lower surface of the base 200 and the floor, or where appropriate, the upper surface of another platform when several of them are stacked. This directing of the efforts directly towards the walls of the posts of the base is ensured when designing said completely vertical walls.
- the function of the filling of foamed material is to reinforce the interior of said columns, in order to increase the load capacity without an increase in consideration of the total weight of the pallet, as well as cushion the impacts suffered by the plastic pallet 100 during daily use. It is important to note that the foamed padding also provides a secure hold of the joints between peripheral posts 210 and 310.
- the central column formed by projections 220 and the means of securing 320 is not filled with foam as is the case with the recesses 340 formed by both sets of peripheral posts of the cover 310 and the base 210 when assembled.
- the injection of the foamed thermoplastic into said recesses 340 allows to avoid the movement by the game that exists between the base and the cover and will give greater grip to the base 200 with the cover 300 that will prevent disassembly during use.
- the material for foaming is selected from the family of polyolefins (low density polyethylene, high density polyethylene, polypropylene and their mixtures), being the same in all these elements, with which at the end of the useful life of the plastic flooring, it can be recycled without requiring a separation of materials.
- polyolefins low density polyethylene, high density polyethylene, polypropylene and their mixtures
- foamed thermoplastic material is also injected into the four sides of the cover 300, in defined areas close to the edge, as indicated by numeral 500 in Figure 1 1.
- This injection of foam in the cover is carried out through the holes 510 so that in addition to reinforcing the areas 500 of the cover 300, the resistance to impact of the four sides of the plastic platform as a whole, and additionally it is possible to generate non-skid zones on the cover 300 precisely in the same injected areas 500, since the foam is exposed to the outside.
- the material to be injected must be sufficiently elastic, being selected from the family of polyolefins (Low density polyethylene PELD, high density polyethylene PEHD, polypropylene PP and other variants or mixtures of these same materials, so as not to affect the advantage of easy recycling of pallet materials at the end of their useful life
- polyolefins Low density polyethylene PELD, high density polyethylene PEHD, polypropylene PP and other variants or mixtures of these same materials, so as not to affect the advantage of easy recycling of pallet materials at the end of their useful life
