Description

DESCRIPTION

Container system

The present invention relates to a container system and, more specifically, to a stackable and / or nestable container system.

The use of nestable and stackable containers for the storage and handling of goods is known. When the containers are full, they are placed in a first direction and stacked on top of each other to protect the merchandise contained in the containers placed below. Empty containers are nestable in a second direction, optimizing empty container return and limiting transportation costs.

Modular type systems are also known, in which the containers are stackable in containers with the same or different dimensions. Such systems are described, for example, in US 4386 700, which is consistent with the preamble of claim 1, DE 2433734, DE 37 18504, FR 2681 048, EP 0770557, GB 2 136399 and GB 1203403.

However, the use of these nestable and stackable containers is not without drawbacks. In fact, these containers are not suitable for the storage and transport of products that can be damaged by the retention of water in the containers. This is the case, for example, of seafood, in particular fish. Another disadvantage of this type of container is that the stacked container stacks are not stable and the containers move relative to one another, since the upper containers are simply placed on the edges formed on the inner surface of the lower containers.

The present invention is defined by a stackable and / or nestable type container system according to appended claim 1.

Products, such as fish, have to be stored and / or transported with ice which, when melted, releases water that can harm the fish. Containers are known in which the bottom and / or the walls are in a mesh or a grid through which water can flow. First of all, this type of surface tends to damage the products contained in the container. Additionally, these surfaces create retention areas that are difficult to clean and unsanitary. Another disadvantage is that, when the filled containers are in the stacked position, the water flows from an upper container to the lower container and comes into contact with the contents of the lower container.

The present invention allows the evacuation of this water out of the containers, thus avoiding contact with the products contained in containers placed in the lower position. In the context of the invention, the "inside of the container" designates the internal volume defined by the bottom and the wall or walls of the container; a container in a "top position" designates a container placed on top of one or more other containers; and a container in a "lower position" designates a container placed under one or more other containers.

The first container comprises a means for evacuating liquid out of the first container and the second container comprises a means for evacuating liquid out of the second container that can be aligned with the liquid evacuation means in the first container. In other words, the liquid evacuation means from the first container and from the second container are adjacent to minimize or prevent the flow of liquid within the containers and, in particular, within the second container. The liquid evacuation means comprises an opening in fluid communication between the interior of the container and the exterior of the container, for example, an opening through the wall and / or the bottom of the container.

The second container comprises stabilizing means that allows the liquid evacuation means from the first container to be aligned with the liquid evacuation means from the second container.

The second container comprises a reinforcement that has the capacity to receive a column of the first container in support, the stabilizing means being located in said reinforcement. The column of the first container has a shape that is substantially complementary to that of the reinforcement to avoid lateral movements of the container in relation to the second container. Stabilizing Medium is an additional means to stabilize stacked containers. The stabilizing means comprise at least one stabilizing rod and preferably two stabilizing rods.

Additionally or alternatively, the second container comprises a slot that has the capacity to receive a column from the first container, the stabilizing means being located in said slot. In practice, the slot of the second container is formed by a column of the second container, with a shape that is substantially complementary to the column of the first container. The stabilizer medium is an additional means to stabilize nested containers. The stabilizing means comprise at least one stabilizing rod and preferably two stabilizing rods.

Preferably, at least one of the columns of the first container comprises a means for evacuating liquid. outside the first container. In accordance with a particularly preferred embodiment of the invention, the columns of the first container are recessed relative to the interior of the container. In this way, the columns do not affect the usable volume of the container and the products placed in the container do not prevent the evacuation of water outside the container.

Preferably, the liquid evacuation means from the first container comprise a liquid evacuation means, for example, an opening, at the base of the column or in an area adjacent to the base of the column. In the system according to the present invention, the water is evacuated out of the container passively as the water naturally accumulates at the bottom of the container and flows through the evacuation means. Evacuation does not require any external intervention, either by the user or mechanically (for example, requiring the use of a pump or other mechanical means). It is interesting to note that the container can be used alone or can be combined with a second container on a system like the one described in this application.

Preferably, the second container comprises an edge that can receive the columns of the first container on support, particularly in the stacked position. This edge makes it possible to reinforce the structure formed by the containers, particularly in the stacked position, to prevent the walls of the second container from protruding under the weight of the first container and its contents.

Preferably, the edge of the second container comprises means for evacuating liquid out of the second container. According to a particularly preferred embodiment of the invention, the edge of the second container comprises a reinforcement that has the capacity to receive a column from the first container in support, the liquid evacuation means from the second container being located in said reinforcement. The reinforcement allows the containers to stack while preventing the containers from moving against each other. The liquid evacuation means from the upper container can be aligned with the evacuation means from the second container to evacuate out of said containers. Thus, when the containers are in the stacked position, the water flowing from the first container is evacuated out of the second container at the edge, under the opening of the second container, without entering the second container and therefore without coming into contact with the contents of the second container.

Preferably, the second container comprises a slot that has the capacity to receive a column from the first container, the liquid evacuation means from the second container being located in said slot. In practice, the slot of the second container will be formed by a column of the second container. Thus, when a first container is nested in a second container with the same dimensions, the columns of the first container are placed in the grooves (or columns) of the second container so that water can flow from one container to another by means of evacuation located at the lower end of the columns of the nested containers.

Preferably, the second container comprises a slot that has the capacity to receive a column from the first container, the stabilizing means being located in said slot. In practice, the slot of the second container is formed by a column of the second container, with a shape that is substantially complementary to the column of the first container. The stabilizer medium is an additional means to stabilize nested containers. The stabilizing means may comprise at least one stabilizing rod and preferably two stabilizing rods.

Preferably, the first container comprises a bottom, said bottom comprising at least one slot in fluid communication with the liquid evacuation means. The slot allows the water from, for example, ice in the container or from the washing of products to be guided towards the evacuation means. Another advantage of a groove (or grooves) is the reinforcement of the bottom of the container.

Preferably, the first container comprises a bottom, said bottom comprising a first surface that is substantially perpendicular relative to the container wall or walls and a second surface that slopes down relative to the first surface and in fluid communication with the medium. evacuation. This second surface guides the water accumulated in the bottom of the container towards the evacuation means.

Another object of the present disclosure is a stackable and / or nestable container system comprising at least a first container and at least a second container, the first container comprising a plurality of columns that allow the first container to be stacked and / or nested with the second container, characterized in that the second container comprises a means for stabilizing the first container relative to the second container.

Preferably, the second container comprises an edge comprising a reinforcement that has the capacity to receive a column from the first container in support, the reinforcement comprising at least one rod that has the capacity to retain the column in said reinforcement.

Preferably, the second container comprises a slot that has the capacity to receive a column from the first container, the slot comprising at least one rod that can retain the column in said slot.

Preferably, the dimensions of the bottom of the first container are smaller than those of the opening defined by the edge of the second container.

According to a particularly preferred embodiment of the invention, said system is a modular type system in which the first container and the second container have different dimensions. The modular system comprises stackable and / or nestable containers with different dimensions.

Preferably, in the case of containers with different dimensions, the first container is stackable in the second container in a first position, and nestable in the second container in a second position that is 180 ° from the first position. The longitudinal walls of the first container will be placed parallel relative to the longitudinal walls of the second container in a first position, and the first container will be rotated 180 ° relative to its vertical axis to nest in the second position.

In the event that the upper container has smaller dimensions than the lower container, the longitudinal walls of the upper container can be positioned perpendicularly relative to the longitudinal walls of the lower container in the stacked position. Furthermore, in the event that the upper container has larger dimensions than the lower container, the containers can be stacked with the longitudinal walls of the upper container positioned perpendicularly relative to the longitudinal walls of one, or preferably, several lower containers.

The stackable and / or nestable container system may comprise at least one evacuation means as defined above and at least one stabilizer means as defined above.

In accordance with another embodiment of the invention, at least one of the side walls of the first and / or second container comprises a lower level part that has a surface higher than a lower level than the upper surface of the rest of said side wall. The lower level part provides a space between the top surface of the container and the bottom of a container stacked on top. The space makes the contents of the container visible for inspection.

Preferably, the upper surface of said lower level portion extends along at least half of the longitudinal extent of said side wall and / or through half of said side wall. For example, the lower level portion may extend along approximately three-fourths of the longitudinal extension of the side wall. Thus, there is a sufficiently wide space between stacked containers for inspection of the container contents.

The lower level portion may be provided on each of two opposite side walls of the first and / or second container. Thus, inspection of the bottom contents of two stacked containers is possible from two sides.

Each of the first and second container may comprise a pair of opposing first side walls and a pair of opposing second side walls extending between said first side walls, where the first side walls are longer than the second side walls, where said lower level part is provided on one or both of said longer side walls. This provides a sufficiently long space for inspection of items in stacked containers.

In one embodiment, at least one or each of the corner portions of the first container comprises a recess for receiving a respective bottom portion of a column of the second container when stacked on top of the first container, wherein the bottom surface of the recess it is at the same level as the level of the upper surface of said lower level part of the side wall of the first container. This feature also contributes to providing a sufficiently large space between stacked containers.

In one embodiment, a part of the upper surface of one of the side walls, or one of each of the opposite pairs of side walls, comprises a mark, or a profile or contour different from the corresponding part of the upper surface of the opposite side wall. For example, said mark or profile or contour is formed by a corrugated upper surface. The corrugated top surface can be provided in a handle portion of the first and second container. These features facilitate correct alignment of containers on top of each other for stacking or nesting as desired.

Another object of the present disclosure is a container for a system as defined above. The container may be such as any one of the first or second containers described above. A container comprising one or more of the features described in relation to any one of the first or second containers described above is also contemplated.

The container 1 illustrated in the figures has a substantially parallelepiped shape that is open at the top and comprises a substantially rectangular bottom 2, two side walls 3, 4 and two longitudinal walls 5, 6. However, containers according to with the present disclosure in different shapes, eg substantially cylindrical or cubic.

Container 1 comprises an edge 7 that extends along the top of walls 3-6. Edge 7 can completely or partially surround the opening created by the upper part of walls 3-6. For example, in the container illustrated in the figures, a grip 8 is located and centered on the top of each side wall 3, 4. Depending on the use, the grips 8 may additionally or alternatively be found on the longitudinal walls. The function of edge 7 is to reinforce container 1 and prevent walls 3-6 from protruding, particularly when full containers are stacked in container 1. When containers are nested, the edge prevents containers from embedding in each other .

Columns 9 are formed on walls 3-6 of container 1. In container 1, columns 9 are integrally formed on walls 3-6. Columns 9 allow a first container 1A to be stacked in a second container 1B in one direction (Figure 6) and allow the first container 1A to be nested in a second container 1B in the opposite direction (Figure 4) after a 180 ° rotation around the container vertical axis 1. Two colors can be used to differentiate the nestable side from the stackable side (ie, two shades).

Columns 9 are hollow to allow nesting of containers. This structure also limits the production costs and lightens the container 1. The columns 9 are lowered in relation to the internal volume of the container 1 defined by the bottom 2, the side walls 3, 4 and the longitudinal walls 5, 6 of the container, so as not to block the usable volume of container 1. In container 1 illustrated in the figures, the hollow columns 9 of the container 1B form a slot 10 that can partially receive, in the nested position, the columns 9 of the container 1A. Columns 9 of container 1A and slots 10 of container 2A substantially form an inverted trapezoid extending from the upper opening of container 1 to the bottom 2 to facilitate insertion of columns 9 into slots 10 and stabilize columns 9 in the grooves 10, but other shapes are also contemplated (eg, substantially conical columns).

The number of columns 9 depends, for example, on the dimensions of container 1. Columns 9 reinforce the walls 3-6 in which they are formed and, therefore, the longer the wall 3-6, the greater the number. of columns 9. Obviously, the number and position of columns 9 on each wall 3-6 facilitate and depend on the stacking and nesting combinations contemplated.

The containers 1 illustrated in the figures comprise two types of means 11, 12 for evacuating liquid out of the containers (Figure 5).

A first evacuation means 11 comprises an opening in the upper part of the container 1, for example, near or at the edge 7 of the container 1. In the figures, the opening is located in a reinforcement 13 formed in the upper surface of the edge 7 The dimensions of the reinforcement 13 are substantially complementary to those of the lower part of a column 9 of a second container, so that the column 9 can be housed and retained therein in the stacked position. In the case of a container without reinforcement, the opening can be located in the upper surface of the edge 7. In the case of a container without a border, the opening can be located in the upper surface of the wall 3-6 or in a flange peripheral. In the event that the columns are formed inside the container, in practice it would be possible to have water evacuation means at the top of the container. However, a container with recessed columns 9 is preferable so as not to block the internal usable volume of the containers. Furthermore, in this type of container, the evacuated water would be redirected inside the lower container.

A second evacuation means 12 comprises an opening at the bottom of a column 9, at the bottom of column 9, in a part adjacent to the bottom of column 9 or at the angle formed by the bottom 2 of container 1 and a column wall 9.

These evacuation means 11, 12 are particularly advantageous in the case of stackable, nestable, stackable and nestable container systems and the containers can also be used alone, particularly if they comprise an evacuation means 12.

The containers 1 illustrated in the figures comprise the following stabilization means 14, 15 of a first container 1A in relation to a second container 2A (Figure 5). The base of column 9 of container 1A is substantially "T" shaped.

Reinforcement 13 constitutes a stabilizing means. Its partially complementary shape of the lower part of the column 9 of the container 1A allows the lateral movements of the container 1A in relation to the container 1B to be reduced or avoided.

The stabilization means 14 improve the stabilization of the container 1A stacked in the container 1B and limit the deformation of the longitudinal walls of the lower container (Figures 7, 8A and 8B). In the containers illustrated in the figures, two rods partially close the reinforcement 13 to retain the column 9 of the container 1A in the reinforcement 13. The rods leave an opening to facilitate the washing of the container and, more specifically, the washing of the reinforcement 13. The rods project from the surface of the reinforcement 13 so as not to block the internal volume of the container 1B. In the figures, the reinforcement 13 receives the horizontal part of the "T" formed by the base of the column 9 of the container 1A and the opening between the rods receives the vertical part of the "T" formed by the base of the column 9 of container 1A.

The grooves 10 constitute a stabilizing means when nesting the containers. Its partially complementary shape to the column 9 of the container 1A allows the lateral movements of the container 1A in relation to the container 1B to be reduced or avoided.

The stabilizing means 15 improves the alignment of the liquid evacuation means from the container 1A with the liquid evacuation means from the container 1B in which it is nested (Figure 5). In the containers illustrated in the figures, two rods are formed at the bottom of the slot 10 and along the walls of the slot 10 so as not to block the liquid evacuation means 12 or the internal volume of the container 1B. The rods are such that the base of the groove 10 has a complementary shape to the base of the column 9 of the container 1A, so that the space between the rods receives the vertical part of the "T" formed by the base of the column 9 of container 1A.

The bottom of container 1A can also have a bottom 2 with dimensions substantially smaller than those of the opening formed by the walls of container 1B to improve the stabilization of container 1A stacked in container 1B and allow container 1A to nest in the container 1B.

The bottom 2 of the container 1 has a smooth surface so as not to damage the products contained in the container, for For example, products like fish and fruits that tend to bruise. This smooth bottom 2 does not have a retention area and facilitates washing of container 1.

Furthermore, the bottom 2 has a structure that improves the evacuation of liquid out of the containers. The bottom 2 of the containers illustrated in the figures comprises grooves 16 that not only allow the bottom 2 to be reinforced, but also that the liquid is directed to the evacuation openings 12. Therefore, the bottom comprises inclined surfaces 17 to guide the liquid to evacuation openings 12.

The filled containers 1 can be stacked by placing columns 9 of the container 1A in reinforcements 13 on the edge 7 of the container 1B. The columns 9 are stabilized in the reinforcements 13 and are retained by rods 14. The evacuation opening 12 of the container 1A is aligned with the evacuation opening 11 of the container 1B in which it is stacked.

In container 1A, water (and / or other liquid) accumulates in the bottom 2 of the container, and is guided by grooves 16 and inclined surfaces 17 to finally evacuate through openings 12 of container 1A. The water passes through the opening 12 of the container 1A to the outside of the container 1A, and then the opening 11 of the container 2A to the outside of the container 2A without entering the internal volume of the container 2A. In this way, the water can be evacuated out of the containers without damaging the products contained in the containers in the stacked position.

Empty containers 1 are nested (Figure 4) by sliding columns 9 of container 1A into slots 10 of container 1B to form a system according to the present invention. Columns 9 of container 1A are maintained in trapezoidal grooves 10 and by stabilizer rods 15 so that the evacuation opening 12 of container 1A is aligned with the evacuation opening 12 of container 1B in which it is nested.

In container 1A, water (and / or other liquid) accumulates in the bottom 2 of the container, and is guided by grooves 16 and inclined surfaces 17 to finally evacuate through openings 12 of container 1A. The water passes through the opening 12 of the container 1A to the outside of the container 1A, and then the opening 12 of the container 2A to the outside of the container 2A without entering the internal volume of the container 2A. Empty containers do not require a drying stage and only nest for one empty turn.

Containers 1 can be used alone or with other containers in a system such as that described above. Liquid evacuation means and column stabilizers can be used alone or in combination in a system according to the present invention.

In a nestable container system, containers 1 preferably have at least one evacuation means in a slot 10. In a stackable container system, containers 1 preferably have at least one evacuation means at one edge 7. In a stacking and nesting containers, the containers 1 preferably have at least one evacuation means of each type.

Furthermore, in a nestable container system, the containers 1 preferably have at least one stabilizing means in one column 9. In a stackable container system, the containers 1 preferably have at least one stabilizing means at one edge 7. In a stacking and nesting containers, the containers 1 preferably have at least one stabilizing means of each type.

Figures 10 to 15 illustrate a nestable and stackable container system in accordance with another embodiment of the present invention. Figure 10 illustrates a first container 20 comprising opposite pairs of long side walls 21 and short side walls 22. The long side walls 21 comprise a part 23 where the upper surface is at a lower level than the upper surface of the remaining part 24 of the long side walls 21. This feature allows the inspection of articles contained in the container 21 when another container 25 is stacked on top, as illustrated in Figures 13 and 14. That is, the lower edge formed by this lower level part of the long side walls 21 provides a space 26 between the bottom of the container 25 and the upper surface of the container 20. The space 26 makes the contents of the container 20 visible for inspection.

One of each of the pairs of long and short side walls 21, 22 comprises a profiled part 27 and 28, respectively. In particular, in parts 27 and 28, the respective side walls 21 and 22 have a corrugated upper surface. The corresponding parts 29 and 30 of the respective opposite side walls 21, 22 have a different (flat) top surface. This feature facilitates stacking or nesting of containers by a user, as illustrated in Figure 13. That is, if the profiled parts 27 and 28 of two containers 20 and 31 are aligned with each other, the top container 20 becomes nested in the lower container 31. On the contrary, if the containers (such as the containers 20 and 25 in Figure 12) are aligned in such a way that the profiled parts 27 and 28 come to reside at opposite ends, the containers can be stacked some about others.

In the illustrated embodiment, the profiled part 28 is arranged in a handle part of the container 20.

As illustrated in Figures 10 and 15, the lower surface 32 of the container 20 comprises a raised central part 33 for directing liquid towards the outlets 34 on the side walls 21 and 22 and the outlets 35 at the corners of the container 20. The effective evacuation of the liquid is further improved by grooves or channels 37, 38, 39 along the side walls 21, 22 and near the outlets 34, 35. In particular, the channels 37 extend into the bottom and along side walls 21, while channels 38 extend at the bottom and along side walls 22. Channels 39 extend perpendicular to channels 37 and advance into channels 37. Channels 37 are delimited on one side by walls 21 and on the other side by longitudinal projections 40 extending parallel to the side walls 21. Similarly, channels 38 are delimited on one side by walls 22 and on the other side by longitudinal projections 41 extending parallel to the side walls 22. The projections 40 are interrupted by the channels 39. The channels 37, 38, 39 as well as the projections 40, 41 are illustrated in more detail in Figures 1 1 and 12.

Figure 11 also shows in more detail the stabilizing means 15 described above in connection with Figure 5.

It is noted that the characteristics shown and described in relation to Figures 10 to 15 can also be provided in the containers shown and described in relation to Figures 1 to 9. In turn, the characteristics shown and described in relation to Figures 1 to 9 can also be provided in the containers shown and described in relation to Figures 10 to 15.
