Technical Field
[0001] The present invention falls within the field of assemblable containers.
Background of the invention
[0002] There are currently two types of containers. First, a cardboard container, which
consists of a cardboard box with tubular pillars, also made of cardboard, located
on top of a wooden pallet. The main drawbacks of this container are its lack of ventilation,
as the box has a thick cardboard bottom, and is situated on top of a second surface,
i.e. the pallet, as well as the low resistance of the container due to the fact that
its sole component is cardboard.
[0003] The second type is a folding container made completely out of plastic. Its main drawback
is its high cost. It is normally rented and must be returned after use, meaning that
it ceases to be viable over long distances, as the logistical costs of returning it
are quite high.
[0004] The present invention proposes a new type of container with a novel make-up.
Description of the invention
[0005] The present invention relates to an assemblable container, constituted of three independent
components, which are easy to assemble together, all of which are reusable or recyclable.
[0006] The container that is the object of the invention is specially conceived to transport
fruit, vegetables, plants, etc., given its high level of ventilation. It is constituted
by a bottom pallet-like platform that makes up the floor or base thereof, an assembly
frame that is mounted on top of the platform, and by a wall that wraps around and
presses against the sides of the assembly frame, closing off the horizontal parts
of the container.
[0007] The robustly built platform is made of a plastic material, and is easy to transport
and store, thanks to the fact that it can be stacked. Moreover, said platform is reusable,
both for building new containers, and for use on its own as a loading platform. Its
size is equal to half a Euro pallet, which facilitates its standardization both in
logistics and in transportation.
[0008] The vertical structure is constituted by simple pieces of solid wood, and is made
up of four stiles or vertical legs, the lower ends of which are fitted and engaged
into the platform, and of four flat horizontal board-based cross beams, two intermediate
ones and two upper ones, placed in parallel, all of which are mounted by their ends
between facing housings in consecutive stiles.
[0009] The stiles have a triangular cross section, forming a right angle, and contain the
grooves into which the boards or horizontal cross beams fit. The intermediate cross
beams, which have a smaller cross-section area than the upper cross beams, are situated
at the same height, between the two consecutive stiles with the shortest distance
between them.
[0010] The upper cross beams are positioned parallel to one another, mounted between independent
pairs of stiles. The housings into which they are engaged consist of vertical grooves
cut from the top end section of the stiles, such that the top longitudinal edge of
these cross beams is flush with said top end section. Because their edge is wider,
greater loads can be supported against the rim of the container, making it more resistant
to compression by channeling the loads along the stiles and the base, thus keeping
the load from being transmitted along the cardboard collar. All of the components
of this assembly frame are reusable.
[0011] In order to make the platforms stackable, their support legs are hollow and nesting,
being closed on the bottom base and open on the top. The bottom base of these support
legs has structures or sockets providing support on top of the stiles and upper cross
beams, so that two or more containers can be stacked, and offering greater resistance
against slippage of the supports.
[0012] The side cover, made of cardboard, is mounted tightly around the stiles, and has
a folded flap along its lower perimeter, the function of which is multiple: on the
one hand, it keeps the cardboard collar from sliding below the level for which it
is conceived, both during assembly and during handling and loading; and on the other
hand, the L-shaped structure it creates, ensures greater rigidity and prevents it
from being deformed. In addition, the notch made when die-cutting this element encircles
the wooden stiles and keeps the collar from rotating horizontally around the structure.
[0013] The cardboard collar is reinforced with peripheral tightening straps that likewise
press the stiles against the cross beams. This is done above the cardboard side cover,
thus helping to distribute the punctual force of the tightening straps, which is distributed
through the cardboard to the stiles, thus ensuring the stability of the assembly frame.
In this way, a stable and uniform structural system is achieved, wherein the wooden
elements absorb compression, and the tightening straps and cardboard absorb traction,
leaving the plastic pallet with the combined function of acting as base and support,
and of balancing forces.
[0014] The side cover has, at least on one of its walls, and starting from the top free
edge of the same, a central area delimited by a perforated or tear line, which when
torn forms a window through which the product contained within is visible, providing
easy access to the same, particularly in the case of bulk products loaded to the minimum
level. At the same time, the area or portion separated by tearing along the aforementioned
perforated line has, starting from its edge, slots enabling it to be mounted upon
the upper edge of the remaining walls of the container, to serve as a stand for displaying
prices or other information. There is also the option of using perforation or die-cutting
to shape a pamphlet holder for commercial purposes; this pamphlet holder is easy to
assemble through its extremely intuitive die-cutting and folding.
[0015] In summary, the container of the invention is made up by means of a series of components
that easily connect to and engage into one another, without the need for accessory
joining elements such as staples, nails, glues, etc.
[0016] Moreover, the side cover or wall, made of cardboard, is easy to recycle, while the
wooden assembly frame and the plastic platform are reusable.
[0017] When disassembled, the volume of all of the elements decreases considerably with
respect to the assembled product.
[0018] With the constitution disclosed herein, the containers can be superimposed or stacked,
since the legs of each platform are provided with a plastic material shaped so as
to secure the stacking position.
[0019] The plastic platforms are reusable, both for building subsequent containers, and
by themselves, as they can be used as loading platforms. Moreover, these platforms
can be stacked up, making them easy to transport and store.
[0020] One more advantage of the container of the invention is its light weight, due to
the nature of the components of which it is made up.
[0021] The characteristics and advantages of the container of the invention may be better
understood with the following description, made in reference to the attached drawings
and illustrations, wherein, by way of example and not limitation, an exemplary embodiment
is shown.

Detailed description of the invention
[0023] As can be seen in Figures 1A, 1B and 1C, the container of the invention is made up
of a reusable bottom platform 1, made of a plastic material, a wooden assembly frame
2 or substructure that can be mounted upon the platform, and a corrugated cardboard
side wall or cover 3 that is wrapped around the assembly frame. It is easy to mount,
by means of sockets.
[0024] Figures 2 to 7 show various views and sections of the container platform:
- Figure 2: top plan view.
- Figure 3: side view along direction A of Figure 2.
- Figure 4: side view along direction B of Figure 2.
- Figure 5: a sectional view of two superimposed and nested platforms cut along the
line VII-VII of Figure 2.
- Figure 6: partial section of the platform taken along the line VIII-VIII of Figure
2.
- Figure 7: elevation view of the top side of the platform.
- Figure 8: elevation view of the bottom side of the platform.
- Figure 9: elevation view of several superimposed platforms.
[0025] The reusable plastic platform 1 has a rectangular outline, as shown in Figure 2,
and its underside has corner support legs or feet 4 and middle support legs or feet
(5,6), all of which are hollow, open on their top base, and closed on their bottom
base. All of these legs have two segments with different cross-section areas, where
the lower segment is the one with a smaller cross-section area, so that when two or
more platforms are superimposed in the same position, as shown in Figures 5 and 9,
the various legs partially nest inside one another, for easy stacking and storage
of said platforms.
[0026] As can be seen in Figures 2 and 6, the inside of the corner support legs 4 are provided
with a diagonal dividing wall 7 delimiting an external housing 8 for mounting the
assembly frame 2, as will be explained further on.
[0027] The bottom of the corner legs 4 takes the shape of a step 9 (Figures 3, 5 and 6),
for easy stacking of the containers. To this end, the middle legs 5 situated on the
longer side of the platform have a central groove 10 (Figure 5).
[0028] The reusable plastic platform 1 may be used by itself as a loading platform. Moreover,
these platforms can be stacked up, as shown in Figure 5, thus making them easy to
store and transport. As can be seen in Figure 2, the reusable plastic platform is
provided with multiple openings (17) that enable the ventilation of the product housed
inside the container.
[0029] The assembly structure 2 of the container, as shown in Figures 10A, 10B, and 10C,
and in Figures 1B and 1C, is made up of four triangular-section stiles 11, and four
cross beams (12, 13), two intermediate ones 12 that are provided between the two consecutive
stiles 11 on the shorter side, and two upper ones 13 mounted between pairs of independent
stiles 11 on the longer side, such that they are in parallel positions.
[0030] The ends of the cross beams (12, 13) are inserted into intermediate housings 18 made
into the stiles 11, as can be seen in Figures 1B and 1C.
[0031] The containers can be superimposed or stacked, as the step 9 in the corner legs 4
of one container sits on the top end of the stiles 11 of the container situated immediately
below it, while the groove 10 in the middle legs 5 on the longer side sits on the
upper edge of the upper cross beams 13, thus securing the stacking position.
[0032] There are three different container sizes, varying in height, whose commercial names
are "G 50" (Figure 10A), "G 70" (Figure 10B) and "G 100" (Figure 10C), indicating
the numerical value of their height in cm. These containers are 80 cm long and 60
cm wide. However, the dimensions of the container in terms of height, width and length
can vary, adapting to any given standard.
[0033] The side cover 3 has, at least on one of its walls, and starting from the top edge
of the same, a central area delimited by a perforated or tear line, which when torn
forms a window through which the product 16 contained within is visible, as shown
in Figure 11, providing easy access to the same.
[0034] There is also the option of using a perforation or die-cutting to shape a pamphlet
holder or pocket 20 for commercial purposes. This pocket 20 is easy to assemble through
its extremely intuitive die-cutting and folding, as shown in Figures 12A, 12B and
12C, which represent different stages in the assembly of the pocket.
[0035] Figure 13A shows the pocket already assembled on the container. Figure 13B shows
an enlarged view of the pocket.
