OBJECT OF THE INVENTION
[0001] The present invention refers to a device that has been specially conceived as a means
of packing, storing, transportation and supplying pulverulent products in flake, gamene
or similar presentations, preferably for product areas such as paints, varnishes,
enamels, dyes, etc.
[0002] The object of the invention is to obtain a device which, after the packing of the
product, permits its easy storage and transportation and optimum emptying conditions
during the consumption of its contents as well as the possibility of reusing all its
elements, eliminating the generation of any type of residues.
BACKGROUND OF THE INVENTION
[0003] As is known, in the preferred practical application of the invention, that of powder
products, as for example paint in powder form, this paint is brought out of the containers
in which it is supplied, either by pouring from the container to the tank of the device
used for application, or by means of aspiration by the venturi effect to spray it
on the surface to be painted with the aid of an electrostatic or triboelectric gun,
to which a jet of air has access, producing a spraying of the same.
[0004] For the use of this type of products, poured by the manual pouring system into the
applicator device tank or in the tank of the machine in which these products are to
be used, there currently exists the solution consisting in the use of an emptying
machine, in which the container or receptacle of the product to be applied is placed,
which, due to its size makes its use in small locations impossible and which additionally
generally requires the aid of a forklift truck for placing the container in the same,
preferably using simple cardboard packs with an internal wrapper and plastic base.
In all cases in which manual pouring does is not produced, an aspiration or ventura
nozzle is used, simply by either inserting said nozzle on the bottom of the container,
or by said aspiration device forming integral part of the emptying machine, in such
a way that the aspiration is complemented with vibration and/or sloping of the container.
In this invention the subsequent form of application of the product is not significant
since the venturi may be directly connected to the application guns or else be used
in the venturi for transferring the product to the actual tank of the machine or more
complex applicator device which includes the guns or other application procedures
or use.
[0005] The problem of this solution is mainly centred, in addition to the need of counting
on a machine such as the one described of considerable size, on the fact that these
containers are not reusable, with the consequent involved repercussion on costs, in
addition to generating residues which sometimes prove to be difficult to remove by
the user; on the other hand they present difficulties for a total use of its contents,
since in their terminal phase, that is to say, when a relatively small layer of product
remains on the bottom of the container, it is difficult to remove by aspiration and
finally involves transportation problems making necessary the aid of pallets for said
handling.
DESCRIPTION OF THE INVENTION
[0006] The device proposed by the invention solves in a totally satisfactory manner, the
previously described problem in the different aspects commented.
[0007] To achieve this, and more specifically, said device is constructed as a container,
with a frusto-pyramidal configuration, divergent towards its mouth with a double function,
on the one hand, to aid the displacement of its contents towards its bottom, and on
the other hand, to additionally aid the lay-up of the empty containers, with the special
particularity that said container is complemented with an internal immovable tray,
in turn in the shape of a rectangular pyramid with appropriate dimensions, to establish,
when it abuts its vertex on the bottom of the container, a perfect fit between its
mouth and the side wall of the container, in such a manner, that said tray constitutes
the bottom of the container compartment of the product established in the centre of
the container, towards the vertex of which, it tends to move, allowing an integral
use of the same without needing to carry out any type of handling in said container,
tending to the final concentration of such a product.
[0008] Thus, each tray is placed inside the corresponding container in a loaded situation
for the device, whilst in unloaded situation, it is capable of being extracted from
the same, the containers being laid-up on one side and the trays on the other, to
minimize its volumetric occupation under storage and transportation conditions.
[0009] In accordance with an embodiment variation of the invention, said internal tray may
be eliminated and replaced by a body which, with the same frusto-pyramidal configuration
as in the previous case, extends by its lower base into a pyramidal section, likewise
rectangular, which mainly substitutes said interior tray, in which case, and in order
to offer stability to the container, said body is complemented with a sustention bedplate,
physically independent from the same, which in turn, adopts the rectangular, frusto-pyramidal
configuration, in this case, divergent in descending direction, open both at the top
and at the bottom, in such a manner, that through its upper mouth it receives inside,
by coupling, the pyramidal section of the container which remains perfectly coupled
and stable in said mouth and includs notches and transversally cut orifices, in correspondence
with its bottom mouth, which permits the passage through the same of the arms of a
truck pallet, a forklift truck or similar, capable of manipulating both the container
as a whole and exclusively, the bedplate in inoperative situation.
[0010] In the first case, that is to say, when said bedplate does not exist, a plurality
of projections, which determine the abutment legs, defining between each other longitudinal
and transversal grooves, open towards the bottom and functionally equivalent to the
bedplate notches, are established at the bottom of the container.
[0011] Logically, both in one case and in the other, said container shall be complemented
with a lid, couplable to its mouth, provided with an over-cover which permits the
insertion inside the container of the venturi or aspiration device, in closed condition,
without requiring the removal of the main lid.
[0012] In any case, the lid shall be in turn provided with a recess, coinciding in shape,
dimension and position with the perimeter of the projections of the bottom and closed
base of the container, in order to facilitate in turn, the stability between containers
during their lay-up in loaded situation, and also equivalent to the lower perimeter
of the bedplate.
[0013] The body of the container shall be provided, on one of its side walls, with a bolt
which, projecting towards the outside, is intended to constitute the attachment means
of a vibrator of any conventional type which aids the descent of the product, avoiding
formation of cavities inside the container.
[0014] The container shall be provided at the level of its mouth with a perimetral flange
to aid the coupling of the lid, as well as with orifices for the immovable coupling
of handles to help with the handling of the containers without hindering its vacuum
lay-up, also counting on trays with handles to aid its manipulation.
[0015] According to this structure, an easily handled device is achieved, which determines
a tightly sealed container, capable of containing a set amount of paint in powder
form or of any other equivalent product, as for example, of approximately 500 Kg.,
which is easily transportable and handled, that assures, with the configuration of
the container involved in the same, the integral consumption of the product housed
inside, that may include in its bottom and free vertex, a plug that aids its cleaning
for subsequent reuse, and that due to its actual structure, very considerably helps
its storage and transportation when empty because they are capable of lay-up by means
of coupling one with the other, the containers on one side and the interior trays
or exterior bedplate on the other, and the corresponding lids also being capable of
independent lay-up and of housing the laid-up bedplates, or the laid-up trays inside
the laid-up bodies, likewise making possible the reuse of all its elements, eliminating
the generation of any type of residues.

PREFERRED EMBODIMENT OF THE INVENTION
[0017] In view of the described figures, and specially Figures 1 through 3, it can be observed
how the device proposed by the invention, according to an embodiment variation of
the same, is constituted as from a body or container (1), with frusto-pyramidal, rectangular
and inverted configuration, of suitable capacity, as for example for a 500 Kg load
of product, the mouth of which, is closed in sealed manner with the collaboration
of a lid (2), coupled to said mouth by any conventional means, said body (1) being
provided at its bottom with a plurality of projections or dimplings (3) which determine
grooves (4), both longitudinal and transversal, with suitable shape and dimensions
to permit the passage through the same, of the arms of a truck pallet or similar,
whilst at the level of its mouth, the body (1) includes a perimetral flange (5), equipped
with orifices (6) that permit the coupling, with immovable or dismountable character,
of handles to facilitate the handling of said container, said flange (5) in turn aiding
the coupling of the lid (2), provided in turn with a perimetral apron (7) for coupling
to the mouth of the body (1), specifically to said perimetral flange (5), said lid
(2) being additionally provided with dimplings (8) positionally coincident with projections
(3) of the bottom of body (1), intended for receiving said projections during their
lay-up between closed containers.
[0018] Similarly, the lid (2) is provided at its centre with an over-cover (9) preferably
of circular configuration, that permits the insertion of the venturi or aspiration
device, without needing removal of said lid (2).
[0019] The body or container (1) is also complemented with an internal tray (10), with a
rectangular pyramidal shape, open at its base, the vertex (11) of which is intended
to abut on the centre of the body or container (1) bottom, in a limit position in
which the mouth of said tray (10) is in contact with the side walls of the container
(1), as can be specially observed in Figure 2, constituting the real bottom of the
container which, due to its pyramidal configuration, aids the concentration of the
product in the area corresponding to its vertex (11), to make easier its extraction.
[0020] Though the product tends to move downwards simply due to the effect of gravity, specifically
to flow over said vertex (11) of the tray (10), it has additionally been provided
that the container (1) includes on the outside, on one of its side walls, near its
mouth, and suitably forming integral par of the same, a bolt (12), intended to constitute
the attachment means to the device, of a vibrator of any conventional type, that helps
the product to descend, preventing formation of cavities of the product inside the
container.
[0021] The trays (10) include handles, not represented in the drawings, that in turn, help
their handling.
[0022] In accordance with this structure, the containers (1), when empty, are inter-coupled
in a male-female manner, to reduce volumetric occupation and to help their storage
and transportation, to which purpose, the projections (3) shall also have a frusto-pyramidal
configuration, on the other hand, the trays (10) being in turn, couplable in similar
manner, with the same purpose and as can be understood from observing Figure 3, the
lay-up of trays (10) capable of being housed inside the container (1) lay-up, specifically
in the interior of the container (1) that adopts the top end position of the corresponding
lay-up.
[0023] In the embodiment variation represented in Figures 4 through 7, body (21) that is
complemented with a similar lid (22), adopts the same frusto-pyramidal, rectangular
and inverted configuration, though its bottom projects downwards, determining a section
(23) tending towards the conical configuration, specifically with a pyramidal, rectangular
configuration, with rounded vertex (24), so that with this configuration for the container,
the same concentration effect of the product as with the tray (10) of the previous
embodiment, is achieved, maintaining the same lay-up possibility when empty, as is
shown in Figure 7.
[0024] In this case, the container body (21) includes at a level with its mouth, the same
perimetral flange (25) and the same orifices (26) suitable for receiving handles that
are physically independent from said body.
[0025] On its part, the lid (22) is equipped with the same perimetral apron (27) for coupling
to the mouth of body (21), and includes a recess (28) suitably shaped and dimensioned
to receive the lower end of a bedplate (29) that complements the device and which
shall be described further on, that is recessed for immobilisation purposes of said
bedplate (29) preventing the transversal displacement during lay-up. Additionally,
lid (22) includes, in a centred position, the same over-cover (30) for inserting the
aspiration device of the product without requiring the removal of the cover (22).
[0026] Bedplate (29) has the specific function of providing body (21) with the stability
it lacks due to the special configuration of its lower end area, and adopts a frusto-pyramidal,
rectangular configuration, suitably shaped and dimensioned to receive, by coupling,
the lower end of the pyramidal section (23) of body (21), specifically through a small
frame (31) that exists in the convergence area between the frusto-pyramidal section
(21) of the body and the pyramidal section (23) of the same, specially visible in
Figure 5.
[0027] This frame (31) includes a recess (32) which in this case houses the bolt (33) that
is functionally equivalent to bolt (12) of the previous case.
[0028] Bedplate (29), evidently open at its top end to permit the coupling frame (31) of
body (21), is also open at its bottom, as can be perfectly observed in Figure 6, is
equipped at the level of its lower mouth and in correspondence with its larger, side
faces with wide rectangular notches (34), suitably spaced and dimensioned to permit
the passage of a truck pallet fork or similar, also establishing for the same purpose
on the smaller side walls, transversally cut grooves or orifices (35), that however,
leave the lower edge (36) continuous to permit the storage of the device in metallic
shelves. Additionally, bedplate (29) includes mortises (37), near its upper mouth,
in the manner of handles, to aid the manipulation of the same when they are found
to be independent from the respective bodies (21).
[0029] The generally frusto-pyramidal configuration of the container bodies (21-23) permits
the male-female coupling between them, as shown in Figure 7, so that the various containers
(21) can be implanted on one single bedplate (29), at the same time that the complementary
bedplates (29) are also male-female coupled to each other and laid-up by being inserted
in inverted position inside the last container (21), as can be deduced by observing
said Figure 7, to minimize its volumetric occupation when empty.
