[0001] The present invention relates to a stackable container, made of plastic material,
with large size and high loading capacity for the storage and transport of products
in general, according to the pre-characterising part of the main claim.
[0002] Within the present context the term "container with large size and high loading capacity"
means containers having a loading volume of at least 500 litres and able to accommodate
loads of at least 500 kg.
[0003] Known containers have, at the terminal bearing part of their feet, a portion, recessed
by about 20 mm, in depth, relative to the remaining portion of the foot, which develops
along the segment of the lower edge of the foot that faces outwards.
[0005] When two containers are stacked, on the walls delimiting this recessed portions bear
the corresponding walls of bearing elements of an underlying container, thereby achieving
a male-female coupling. These bearing elements can be provided projecting from the
upper edge of the lateral walls of the container or projecting from a lid of the container.
Thanks to the shape coupling between the recessed portions of the feet and the projecting
portions of the bearing elements, a stable bearing of a container above the other
without the possibility of transverse or longitudinal movements of the upper container
relative to the one that supports it.
[0006] This recessed portion of the feet of known containers creates drawbacks. It occurs
that in systems for automatically moving the containers, e.g. on conveyor rollers,
the devices for detecting the presence of the containers in determined positions,
when they are provided in very low positions, i.e. substantially at the bearing surface
of the containers, cannot "read" the presence of a container. It has been verified
experimentally that this occurs often, especially when photoelectric cells are used
as detecting devices.
[0007] An additional drawback is that in known conveyor systems, the continuous recessed
portion along the outer lower edge of the feet causes the containers not to move smoothly.
[0008] A further drawback is that when the containers are stored on "racks" i.e. on shelves
of limited dimensions whereon bears only the outer part of the feet, the bearing surface
of the feet, being partly limited by the presence of the recessed portion, is not
always sufficient to assure an optimal and stable housing of the container.
[0009] An object of the present invention is to provide a container which, whilst continuing
to assure the possibility of a stable stacking of the containers, in particular with
regard to transverse and longitudinal displacements of the stacked container relative
to the supporting container, is able to overcome the drawbacks linked to the failure
to detect the feet of the containers by the detecting devices, in particular by the
photoelectric cells, reduces the problems of "sticking" of the containers when they
are moved and assures a better and more stable positioning of the containers on the
racks.
[0010] These and other objects that will be readily apparent to those skilled in the art
are achieved by a container in accordance with the characterising part of the main
claim.
[0011] For a better understanding of the present invention, drawings are provided by way
of non limiting example, in which:
fig. 1 shows a schematic perspective bottom view of a container according to the invention,
fig. 2 shows an enlarged view of a detail,
figs. 3, 4 and 5 show respectively plan, bottom, and lateral views thereof,
fig. 6 shows a partial, enlarged, schematic lateral view of a container on a rack.
The aforementioned figures show a stackable container according to the invention,
made of plastic material, with large size and high loading capacity for the storage
and transport of products in general. The container, as is conventional for those
skilled in the art, comprises a polygonal base wall 1, lateral walls 2, 3, 4, 5, able
to delimit with said base wall a compartment 6 for containing the products, feet 7
branching off at the angles 8 of said base wall and additional feet 7A, 7B provided
centrally along the perimeter of the base 1 and at the centre thereof, able to distance
said base wall 1 from a bearing surface 9 (fig. 5) of the container, and a plurality
of upper step-shaped angular elements 16 for at least the partial bearing of the feet
7 in a container stacked on an underlying container.
[0012] The feet 7 of the container shown in the figures are of the type shaped as cross-members,
i.e. with conventional elongated elements 20 that mutually connect the feet along
the greater side of the container and that are removably associated in snap-in fashion
in conventional seats (not shown, but conventional for those skilled in the art) provided
in the feet themselves 7. However, the invention as shall be clarified below, is applicable
both in containers with feet lacking cross members and in containers with cross members,
as well as in containers comprising feet only at the angles 8 of the base 1. A similar
situation also holds true for the conformation of the lateral walls 2-5 that in the
example shown are constructed in a single piece with the base 1 but which, as is conventional
for those versed in the art, could be associated to the base 1 by means of hinges,
thereby being able to be lowered on the base 1 itself, in order to save space when
the container is not to be used. A container of the type described above is known
and will therefore not be further described.
[0013] According to the invention, the feet 7 provided in the angles 8 of the base 1 have,
at the greater side of the container and at their outer wall 10 (fig. 2) a split in
two portions 11, 12, in which one (11) of said portions is recessed relative to the
other (12) thereby delimiting a recessed seat 14 in said outer wall 14. This seat
is delimited only by three walls 15A, B, 18 in such a way as to be open at the face
or wall of the foot 21 oriented towards the bearing surface 9 of the container, a
the lateral outer face or wall 10 of the foot and at a wall 22 (fig. 1) oriented towards
the interior of the base of the container, i.e. towards the other angular foot of
the cross member 20. The recessed seat 14 preferably has a contour in the shape of
a right angle trapezoid thereby favouring the penetration of the bearing elements
16 when two containers are stacked. The bearing elements 16 comprise for each angular
foot, a first part 19 (fig. 5) able to serve as a support for the lower surface 12A
(fig. 4) of said not recessed portion 12, and a second part 17 projecting relative
to the first (19), having a shape and dimensions matching those of the seat 14, and
able to engage in said recessed seat, in contact with the walls 15A 15B and 18 which
delimit it, thereby preventing substantial longitudinal or transverse displacements
of the stacked container relative to the underlying container.
[0014] The recessed seat 14 is provided in the area of the foot able to come in contact
with the bearing surface and it preferably has a maximum height h (fig. 5) equal to
about 1/3 of the height H of the foot, a maximum width 1 equal to about 1/2 of the
width L of the foot and a maximum depth p (fig. 4) equal to about 1/3 the depth P
of the foot in the case of containers with dimensions 1200X800 mm, and about 1/5 in
the case of containers with larger dimensions.
[0015] Thanks to the particular shape of the foot, described above, the containers according
to the invention are always detected by the detection devices of the related conveying
systems, because even if said devices are pointed to a height corresponding to the
one where the seat 14 is provided, at said height the container has a portion 12 of
the foot lacking recesses, i.e. a portion that has a wall 27 (fig. 2) that is substantially
continuous with: the visible surface of the foot itself, the corresponding surface
25 of the base 1 and the surface 26 of the parts 2, 4. This shape of the foot 7 together
with the fact that the recessed seat 14 is provided only on one of the outer faces
of the foot, preferably the face of the greater side of the container, also assures
a reduced risk of sticking of the containers when they are moved on conveying systems,
e.g. of the roller type.
[0016] Moreover, as shown in figure 6, thanks to the fact that the recessed seat 14 does
not extent, as in traditional containers, also at the angle to the foot 7, the bearing
surface of the feet is larger and when the containers are housed on shelves of limited
size i.e. racks 9A, the containers are housed in a more stable manner on said racks.
[0017] Lastly, it should be repeated that the embodiment illustrated hitherto is provided
purely by way of example and that numerous variants are possible without departing
from the same inventive concept. Thus, for example, the seat 14 could be provided
in a different position, e.g. more central relative to the one shown, and have only
two openings, one at the outer face 10 of the foot and one at the face 21 (fig. 2)
that bears on the bearing surface 9, said variant would also entail obvious modifications
of the upper edge 9 of the container.
[0018] Alternatively, the seat could also have only one opening at the face 12A that bears
on the bearing surface, but it should be noted that since the seat 14 has to be copenetrated
by the projecting parts 17 provided on the upper edge of the lateral walls of the
container the latter variant would limit the dimensions of this male-female coupling
reducing the stability of the stacking in case of containers with very large dimensions
or loads.
[0019] According to another variant, the bearing elements 16 could be provided on the edge
of a convention lid (not shown) able to close the container.
[0020] According to an additional variant if the container, in addition to feet 7 provided
in the angles of the base 1 also provides additional feet provided for example in
central positions of the perimeter of said base or at its centre (indicated as 7A
and 7B in fig. 19) these additional feet can have either a recessed seat 14A (fig.1)
that extends over the entire length of the foot (as in the case of the peripheral
central feet 7A) or as shown previously for the angular feet 7 a seat 14B that extends
only for a portion of said length (as in the case of the seats of the central foot
7B).
[0021] An additional variant pertains to the outer surface of the feet lacking the recessed
seat 14 which can be smooth or, as shown in the drawings, can have a plurality of
vertical fins 27 for protecting the feet themselves.
