- the supporting squares have a trapezoidal shape that is designed to be arranged on the upper frames, and the thickness thereof is substantially equal to the recess of the upper frames in relation to the contiguous side walls. Furthermore, the supporting squares have a through-hole close to the vertex and two internal cylindrical hollows close to the side edges thereof.
- the height of the spreader/anchor parts is substantially equal to the height of the containers and said spreader/anchor parts include a head with a base with a specially shaped plan designed to facilitate stacking of the containers, the lower portions of which are attached to two flat X-shaped plates and four lugs arranged between said flat plates.
- the system according to the invention includes firstly containers 10 for storing and transporting perishable products, and secondly supporting squares 41 for the corner zones 15 of the containers 10 and spreader/anchor parts 51 for the containers 10.
- the containers 10 are designed to be stacked by fitting into one another when empty (see figures 10a, 10b, 10c ) and to be stackable on top of one another when containing perishable products (see figures 9a, 9b ) in assemblies of rows and columns positioned in particular on pallets 60 in combination with the supporting squares 41 and the spreader/anchor parts 51.
- the containers 10 are formed (see figures 1 and 2 ) by bases 11, side walls 13 and corner zones 15 made of plastic materials.
- the bases 11 and the side walls 13 are formed, with the exception of the edges thereof, by a grid of strips arranged in two directions (as in other containers known in the prior art), forming therebetween a plurality of square and/or rectangular orifices 17.
- the side walls 13 are arranged with an angle of inclination greater than 90° in relation to the bases 11 thereof to enable stacking.
- the difference between the containers 10 according to the invention and the containers known in the prior art lies in the corner zones 15 that are designed (see figure 3 ) with curved walls 20 and upper frames 31.
- the curved walls 20 include a central section 23 and two end sections 21 adjacent to the side walls 13, in the form of cone segments, the vertex of the end sections 21 being oriented towards the upper portion of the container 10 and the vertex of the central section 23 being oriented towards the base 11 thereof.
- the curved walls 20 are arranged with an angle of inclination in relation to the bases 11 that is substantially equal to the angle of inclination of the side walls 13 to facilitate stacking thereof (see figure 2 ).
- the upper frames 31 have an external outline formed by straight sections aligned with the side walls 13 contiguous to the corner zone 15 and a curved internal outline fitting the upper edge of the central section 23 of the curved walls 20.
- the upper frames are recessed in relation to the contiguous side walls 13 and have a through-hole 33 in the vertex and two cylindrical projections 35 in the edges thereof contiguous to the side walls 13.
- the supporting squares 41 for the corner zones 15 have a pentagon shape designed to be placed on top of the upper frames 31 of the containers 10, and are wide enough to cover the recess thereof in relation to the lateral walls 13.
- the vertex thereof has a through-hole 43 arranged to be positioned above the through-hole 33 of the upper frames 31 and the ends thereof have two internal cylindrical hollows 45 arranged to seat the cylindrical projections 35 of the upper frames 31.
- the supporting squares also have side harpoons 48 that facilitate the snap-fitting thereof to the container 10, such that a container 10 with four supporting squares 41 arranged in the corner zones 15 thereof form a one-piece assembly. Reinforcing ribs are provided on the lower portion of the supporting squares 41.
- bodies 46 designed to cooperate with the cylindrical projections 35 of the upper frames 31 are arranged such to be rigidly connected together when a supporting square 41 is positioned on an upper frame 31.
- the cylindrical projections 35 are not solid, but are hollow with an end neck designed to receive the bodies 46.
- the supporting squares 41 for the corner zones 15 are designed to facilitate the stacking of containers 10 containing perishable products, preventing the containers from entering the container located below (which would occur in the absence of supporting squares).
- Figure 6 shows a stack of a first container and a second container with curved walls 20, 20' respectively (see also figure 7 ).
- the curved walls 20' of the second container rest on the supporting squares 41 located in the corner zones of the first container.
- the supporting squares 41 located on the curved walls 20' of the second container enable another container to be stacked thereupon.
- the spreader/anchor parts 51 are intended to secure and facilitate the ventilation of an assembly of containers 10 arranged in particular in rows and columns on a pallet 60 (see figures 9a and 9b ).
- This assembly is formed by 36 containers 10 containing perishable products and arranged in six rows and six columns, each container 10 resting on the container positioned below in the same column, for which purpose all of the corner zones of the containers 10 are provided with supporting squares 41.
- This assembly also includes spreader/anchor parts 51 in the areas in which the corner zones of four containers 10 come together. Consequently, in the example shown in figures 9a and 9b , twelve spreader/anchor parts 51 enable the assembly of 36 containers to be secured.
- the height of the spreader/anchor parts 51 is substantially equal to the height of the containers 10 and said parts include (see figures 5a, 5b ) two flat plates 59 that are arranged perpendicularly in an X shape and joined to the base 55 of a head 53, the sides of which include curved zones 58 in the central portion thereof to facilitate stacking of the containers, as well as four lugs 57 arranged between said flat plates 59.
- the head 53 is designed as a rebate on the base 55 with reinforcing ribs 56.
- This arrangement of the spreader/anchor parts 51 has the advantage of facilitating self-positioning of the containers when the containers are stacked on top of one another.
- the curved zones 58 act as guides or slides to stack the containers correctly.
- Figure 8 shows a first container 10 and a second container 10' containing perishable products being stacked.
- Figure 8 shows how the lugs 57 of the spreader/anchor parts 51 located on the containers 10 and 10' pass through the through-holes 43 of the supporting squares 41 of the corner zones and the through-holes 33 of the upper frames 31 of said containers 10 and 10'.
- the other three lugs 57 of the spreader/anchor parts 51 engage in the through-holes 43 and 33 of, respectively, the supporting squares 41 and the upper frames 31 of the three contiguous containers located in the same row.
- the spreader/anchor parts 51 are designed to be inserted in four contiguous corner zones 15 of four containers, the head 53 thereof finally being positioned on a portion of the supporting squares 41 of these corner zones 15 and with the flat plates 59 thereof arranged perpendicularly along the directions (longitudinal and transverse) of the side walls 13 of the containers 10.
- An important advantage of the invention is that the special arrangement of the corner zones 15 of the containers 10 and the combination thereof with the flat plates 59 of the spreader/anchor parts 51 (that are positioned in line with the longitudinal and transverse sides of the containers) along with the open arrangement of the upper portion of the containers 10 (since the supporting squares 41 only cover the corner zones 15) enable air to flow through an assembly of stacked containers 10 (as shown in figures 9a and 9b ) in all directions.
- the containers 10 according to the invention are especially suited to use in cooling systems commonly referred to as "Californian tunnels”.
- "Californian tunnels" or rapid-cooling tunnels are used to rapidly cool goods, based on a system providing greater air pressure and quantity than rapid-cooling chambers. Such tunnels can be used to cool any type of goods, fresh or frozen.
- the tunnels have a double bottom containing electric fans with greater power and capacity than evaporators. These electric fans raise the pressure of the air flow so that the air can pass through the palletized fruit more often by unit of time, and therefore the cooled air reaches the center of the pallet more quickly.
- the pallets must be arranged such that the gaps therebetween create air flow tunnels. These circuits must be correctly designed to achieve the required air pressure.

WO 01/54993 - Spanish utility model
1030289 - For certain perishable products, such as grapes for example, it is beneficial to store and transport same using pallets carrying an assembly of boxes arranged in rows and columns.
- However, with the boxes described in Spanish utility model
1030289 - The present invention is intended to address these drawbacks.
- The invention provides a system for storing and transporting perishable products that includes three components that are preferably made of plastic materials: (a) rigid containers for storing and transporting perishable products that are designed to be stacked, with each container fitting into the container below, (b) supporting squares for the corner zones of the containers to enable the containers to be stacked by arranging one on top of another once the containers contain perishable products, and (c) spreader/anchor parts to secure assemblies of containers stacked in rows and columns.

Figures 9a and 9b are respectively elevation and plan views of an assembly of 36 containers stacked in an assembly formed by six rows and six columns, arranged on a pallet. -
Figures 10a, 10b and 10c are respectively perspective and side elevation views of an assembly of 36 empty containers stacked in an assembly formed by six rows and columns, arranged on a pallet. - The system according to the invention includes firstly
containers 10 for storing and transporting perishable products, and secondly supportingsquares 41 for thecorner zones 15 of thecontainers 10 and spreader/anchor parts 51 for thecontainers 10. - The
containers 10 are designed to be stacked by fitting into one another when empty (seefigures 10a, 10b, 10c ) and to be stackable on top of one another when containing perishable products (seefigures 9a, 9b ) in assemblies of rows and columns positioned in particular onpallets 60 in combination with the supportingsquares 41 and the spreader/anchor parts 51. - In the embodiment of the invention described in detail, the
containers 10 are formed (seefigures 1 and 2 ) bybases 11,side walls 13 andcorner zones 15 made of plastic materials. - The
bases 11 and theside walls 13 are formed, with the exception of the edges thereof, by a grid of strips arranged in two directions (as in other containers known in the prior art), forming therebetween a plurality of square and/orrectangular orifices 17. Theside walls 13 are arranged with an angle of inclination greater than 90° in relation to thebases 11 thereof to enable stacking. - The difference between the
containers 10 according to the invention and the containers known in the prior art lies in thecorner zones 15 that are designed (seefigure 3 ) withcurved walls 20 andupper frames 31. - The
curved walls 20 include acentral section 23 and twoend sections 21 adjacent to theside walls 13, in the form of cone segments, the vertex of theend sections 21 being oriented towards the upper portion of thecontainer 10 and the vertex of thecentral section 23 being oriented towards thebase 11 thereof. As a whole, thecurved walls 20 are arranged with an angle of inclination in relation to thebases 11 that is substantially equal to the angle of inclination of theside walls 13 to facilitate stacking thereof (seefigure 2 ). - The
upper frames 31 have an external outline formed by straight sections aligned with theside walls 13 contiguous to thecorner zone 15 and a curved internal outline fitting the upper edge of thecentral section 23 of thecurved walls 20. The upper frames are recessed in relation to thecontiguous side walls 13 and have a through-hole 33 in the vertex and twocylindrical projections 35 in the edges thereof contiguous to theside walls 13. - The supporting
squares 41 for the corner zones 15 (seefigures 4a, 4b and 4c ) have a pentagon shape designed to be placed on top of theupper frames 31 of thecontainers 10, and are wide enough to cover the recess thereof in relation to thelateral walls 13. The vertex thereof has a through-hole 43 arranged to be positioned above the through-hole 33 of theupper frames 31 and the ends thereof have two internalcylindrical hollows 45 arranged to seat thecylindrical projections 35 of theupper frames 31. The supporting squares also haveside harpoons 48 that facilitate the snap-fitting thereof to thecontainer 10, such that acontainer 10 with four supportingsquares 41 arranged in thecorner zones 15 thereof form a one-piece assembly. Reinforcing ribs are provided on the lower portion of the supportingsquares 41. - In the internal
cylindrical hollows 45,bodies 46 designed to cooperate with thecylindrical projections 35 of theupper frames 31 are arranged such to be rigidly connected together when a supportingsquare 41 is positioned on anupper frame 31. For this purpose, thecylindrical projections 35 are not solid, but are hollow with an end neck designed to receive thebodies 46. - Consequently, when the supporting
squares 41 are placed on thecontainers 10, the structural behavior of the assembly is enhanced since thecontainers 10 are further stiffened, which helps each container to withstand the weight of the containers located above said container in the same column. - The supporting
squares 41 for thecorner zones 15 are designed to facilitate the stacking ofcontainers 10 containing perishable products, preventing the containers from entering the container located below (which would occur in the absence of supporting squares). -
Figure 6 shows a stack of a first container and a second container withcurved walls 20, 20' respectively (see alsofigure 7 ). The curved walls 20' of the second container rest on the supportingsquares 41 located in the corner zones of the first container. The supportingsquares 41 located on the curved walls 20' of the second container enable another container to be stacked thereupon. - The spreader/
anchor parts 51 are intended to secure and facilitate the ventilation of an assembly ofcontainers 10 arranged in particular in rows and columns on a pallet 60 (seefigures 9a and 9b ). - This assembly is formed by 36
containers 10 containing perishable products and arranged in six rows and six columns, eachcontainer 10 resting on the container positioned below in the same column, for which purpose all of the corner zones of thecontainers 10 are provided with supportingsquares 41. - This assembly also includes spreader/
anchor parts 51 in the areas in which the corner zones of fourcontainers 10 come together. Consequently, in the example shown infigures 9a and 9b , twelve spreader/anchor parts 51 enable the assembly of 36 containers to be secured. - The height of the spreader/
anchor parts 51 is substantially equal to the height of thecontainers 10 and said parts include (seefigures 5a, 5b ) twoflat plates 59 that are arranged perpendicularly in an X shape and joined to thebase 55 of ahead 53, the sides of which includecurved zones 58 in the central portion thereof to facilitate stacking of the containers, as well as fourlugs 57 arranged between saidflat plates 59. Thehead 53 is designed as a rebate on thebase 55 with reinforcingribs 56. This arrangement of the spreader/anchor parts 51 has the advantage of facilitating self-positioning of the containers when the containers are stacked on top of one another. Thecurved zones 58 act as guides or slides to stack the containers correctly. -
Figure 8 shows afirst container 10 and a second container 10' containing perishable products being stacked.Figure 8 shows how thelugs 57 of the spreader/anchor parts 51 located on thecontainers 10 and 10' pass through the through-holes 43 of the supportingsquares 41 of the corner zones and the through-holes 33 of theupper frames 31 of saidcontainers 10 and 10'. - Similarly, the other three
lugs 57 of the spreader/anchor parts 51 engage in the through-holes squares 41 and theupper frames 31 of the three contiguous containers located in the same row. In this regard, it can be seen that the spreader/anchor parts 51 are designed to be inserted in fourcontiguous corner zones 15 of four containers, thehead 53 thereof finally being positioned on a portion of the supportingsquares 41 of thesecorner zones 15 and with theflat plates 59 thereof arranged perpendicularly along the directions (longitudinal and transverse) of theside walls 13 of thecontainers 10. - An important advantage of the invention is that the special arrangement of the
corner zones 15 of thecontainers 10 and the combination thereof with theflat plates 59 of the spreader/anchor parts 51 (that are positioned in line with the longitudinal and transverse sides of the containers) along with the open arrangement of the upper portion of the containers 10 (since the supportingsquares 41 only cover the corner zones 15) enable air to flow through an assembly of stacked containers 10 (as shown infigures 9a and 9b ) in all directions. - In this regard, it should be noted that with many perishable products, and specifically fruit such as grapes, good preservation depends essentially on the fruit being cooled rapidly following harvesting, and as such the
containers 10 according to the invention, stacked on pallets, facilitate the cooling of the fruit, either during transportation or storage, since the flow of cooled air in all directions helps to optimize cooling both in terms of time and cost. - Very specifically, the
containers 10 according to the invention are especially suited to use in cooling systems commonly referred to as "Californian tunnels". - "Californian tunnels" or rapid-cooling tunnels are used to rapidly cool goods, based on a system providing greater air pressure and quantity than rapid-cooling chambers. Such tunnels can be used to cool any type of goods, fresh or frozen. The tunnels have a double bottom containing electric fans with greater power and capacity than evaporators. These electric fans raise the pressure of the air flow so that the air can pass through the palletized fruit more often by unit of time, and therefore the cooled air reaches the center of the pallet more quickly. The pallets must be arranged such that the gaps therebetween create air flow tunnels. These circuits must be correctly designed to achieve the required air pressure.
- Although the present invention has been described with reference to multiple embodiments, it is clear from the description that multiple combinations of elements, variations or improvements thereof are possible within the scope of the invention defined in the attached claims.

- The system as claimed in claim 1, in which said upper frames (31) have through-holes (33) close to the vertices of same and two cylindrical projections (35) arranged on the edges thereof adjacent to the side walls (13).
- The system as claimed in any one of claims 1-2, in which the curved walls (20) include a central section (23) in the form of a cone segment with the apex oriented towards the base (11) and two end sections (21) that are adjacent to the side walls (13), in the form of cone segments with the apex oriented towards the upper portion of the container (10).
- The system as claimed in any one of claims 1-3, in which said supporting squares (41):- have a trapezoidal shape that is designed to be arranged on the upper frames (31),- have a thickness that is substantially equal to the recess of the upper frames (31) in relation to the contiguous side walls (13),- have a through-hole (43) close to the vertex, two internal cylindrical hollows (45) close to the side edges thereof, and two side harpoons (48).
- The system as claimed in claim 4, in which the cooperating means of the upper frames (31) and the supporting squares (41) are respectively the two cylindrical projections (35), the two internal cylindrical hollows (45) and the two side harpoons (48).
- The system as claimed in claim 5, in which the two cylindrical projections (35) and the two internal cylindrical hollows (45) are designed to be rigidly connected together when a supporting square (41) is positioned on an upper frame (31).
- The system as claimed in claim 6 in which the cylindrical projections (35) are hollow and the internal cylindrical hollows (45) have bodies (46) designed to be inserted in the cylindrical projections (35).
- The system as claimed in claim 1 in which the cooperating means of the upper frames (31), the supporting squares (41) and the spreader/anchor parts (51) are firstly through-holes (33, 43) of respectively the upper frames (31) and the supporting squares (41) and secondly the lugs (57) of the spreader/anchor parts (51).
- The system as claimed in any one of claims 1-8, in which the containers (10), the supporting squares (41) and the spreader/anchor parts (51) are made of plastic materials.
