PALETTE AMELIOREE

PALLET

Abrégé anglais

Perfected pallet characterized because it is formed of
a body in a single piece formed by molding in plastic,
preferably with a mixture of polyethylene and --
polypropylene, whose body has a quadrangular flat portion
of reduced height from one of whose large surfaces emerge
a series of perpendicular prismatic portions, parallel
and facing each other, between which are spaces to
introduce and couple mechanical elements to raise the
load placed on the upper face of the body, and which the
flat quadrangular upper face has regular and/or irregular
perforations over it.

PERFECTED PALLET
The object of the present invention is a perfected
pallet.
Pallets presently found in the market for the system
of palleting merchandise consist basically of a base
formed by transversal wooden slats supported by lengths
of the same material. They are joined by nails and the
assembly is carried out pneumatically or similarly.
The innovation it is desired to protect consists of
the pallet being made of plastic using a mixture of
polyethylene and polypropylene to form a single block or
structure that offers the following advantages against
the present one made of wood:
* Uniformity is obtained in the resistance of the
pallet made in this way since the injection system allows
dosification with respect to the components which makes
the resistance of the pallet uniform. In existing wooden
pallets there may be transversal slats of deteriorated
wood since wood is a "living" material with knots and
veins that makes uniform or continuous resistance in the
pallet impossible.
* The pallet of the invention allows an important
weight reduction since its manufacture by the injection
system reduces its weight by at least half.
* Injection avoids the disadvantages of splintering
and of points and nails that appear in conventional
pallets and scrape the merchandise stored on them, and
also can cause accidents to operators handling the
pallet.
* The thickness of the support surface of the
pallet of the invention may vary to give more resistance
according to the load to be palleted, so that loads or
merchandise with little weight can be palleted with
pallets of small thickness and loads of greater weight

21~91~1
on pallets with greater thickness or weight. Also during
injection a reinforcement system can be added using fibre
glass which undoubtedly gives additional resistance.
* The continuous surface of the pallet can have
roughness or granulation so that the merchandise it
supports cannot slip and also perforations to decrease
weight or lower the cost of manufacture.
* The manufacturing system allows cleaning and
washing with soaps and detergents and also brushing if
necessary, which is difficult with those currently known
since water can make wood expand or deform. The pallet
of the invention can be stored outdoors without any
additional type of protection.
* Against present wooden ones, the pallet of the
invention can incorporate the advantage of being able to
print the brand or logo of the user, either with paint
because of the large surface of the new pallet, or
moulded and indelible during the injection system.
* The mixtures of polypropylene and polyethylene,
and certain additions to the mixture, make the pallets
flameproof which is an important safety advantage over
those of wood presently commercialized.
* Resistance to humidity and knocks facilitates
pallet handling, and it is also hygienic and well
ventilated as well as having a minimum and constant
weight, and the possibility of being produced in any
colour.
Definitively, the pallet of the invention can vary
in thickness, measurements and additional details for the
use of palleting loads, in a monobloc system based on
injection with the advantages indicated above.
According to the invention, the pallet is formed by
a body in a single piece, made of plastic with a mixture
of polyethylene and polypropylene.
The pallet has a quadrangular surface and on one of
its faces has some prismatic salients in a transversal

21~9i~1
and parallel direction, also prismatic in shape, located
at the ends and in the central part that define some
coupling grooves for the forks of the lifting machines
of this type.
In order to more easily understand not only the
formation but also the usefulness and use of the pallet
of the invention, reference is made below to a practical
example of manufacture, with this execution being merely
enunciative and in no case limiting the same, all as
shown in the attached drawings, in which:
Figure 1 shows a perspective view of the pallet of
the invention.
Figure 2 shows a front view of the top face.
Figure 3 shows a lateral view of the pallet.
With reference to the drawings they show the pallet
1 of the invention.
The pallet 1 is formed by a single body 2 that has
a quadrangular portion 3 of reduced height.
One of the sides, referenced with number 4, has some
prismatic salient portions 5 and 6.
The portions 5 are at the ends and the portion 6 is
centrally placed so that between each of the two
consecutive portions some spaces 7 are defined.
The fact 8 of the quadrangular portion 3 forms the
support surface for the load.
Having sufficiently described the nature of the
invention and the manner of putting it into practice, it
should be noted that the layouts indicated above and
represented in the attached drawings may be modified in
detail provided the basic principle is not altered.
