Definitions

  • the present invention relates to a cooling box for transporting cooled products in a transport vehicle and/or for distributing cooled heat-sensitive products or perishables to final customers.
  • the invention also relates to a method for transporting heat-sensitive products together with other transport containers from a supply center to final customers.
  • Usual cooling boxes use exchangeable cool packs for keeping goods cool in the box for a certain period of time. It is also known to use carbon dioxide snow instead of cool packs. An example for such a system is described in WO 2011/086265 A1 .
  • the device for transporting and distributing heat-sensitive products as described in this document allows commissioning of the box with heat-sensitive products through an upper commissioning opening, and the temperature in the box in maintained by a bag filled with a required amount of carbon dioxide snow.
  • cooling boxes are also known, e. g., from US 6 212 901 B1 (which forms the basis for the preamble of claim 1), US 2 393 245 A , US 5 890 613 A , WO 97/18422 A1 , US 2004/200232 A1 , WO 95/25253 A1 , DE 10 2013 003008 A1 . It is an object of the present invention to create a cooling box, which is designed to be transported together with other cooling boxes and/or together with other kinds of containers in a transport vehicle. Another object of the present invention is to provide a cooling box in which different kinds of heat-sensitive products and/or perishables requiring different transport temperature ranges can be transported, in particular deep frozen food and fresh food like milk products or meat.
  • Yet another object of the present invention is to avoid any dangerous handling or misuse of cool packs or cooling material by customers or personal of a supply service.
  • An additional object of the present invention is to create a method in the sense of a complete supply system for transporting and distributing heat sensitive products from a distribution center to final customers via transport vehicles.
  • a cooling box as solution for the above object is defined in independent claim 1.
  • the corresponding method for transporting and distributing heat-sensitive products is defined in independent claim 13.
  • a cooling box for transporting heat-sensitive products in a transport vehicle and/or for distributing heat-sensitive products to final customers comprises:
  • a main aspect of the present invention relates to the interior of a cooling box.
  • the box according to the present invention has a thermally insulating cuboid housing with a commissioning opening on an upper side.
  • the housing contains a first and a second storage chamber, which can be designed for one or two different temperatures, both together surrounded on five sides by the housing and open on the upper side.
  • a cover is used to open and close the commissioning opening of the housing, wherein the cover contains an integrated cool pack to be filled, cooled down and/or exchanged in a supply center, in particular by use of service tools only. This means that the cool pack is not a separate part and the cooling medium is not directly accessible to persons using the box for transport of goods in the intended way.
  • the volume of the first and second chambers may be variable as well as their areas of contact to the cool pack and their thermal insulations.
  • cooling box the special situation in a transport vehicle was taken into account in a preferred embodiment.
  • Usual orders of customers require transporting boxes of beverages, cooling boxes and other transport containers in the same vehicle.
  • To do this in a safe and handy manner it is necessary to place the heavy loads on the ground and to form stacks with the light weight containers on top.
  • the most appropriate way is to place beverage boxes on the ground of the cargo compartment of the transport vehicle and to place cooling boxes on top of them completing the stack by other transport containers on top of the cooling boxes.
  • cooling boxes according to the present invention need a profiled outer bottom plate to cooperate in a form locking manner with a certain underlying raster, in particular the upper side of beverage boxes.
  • a profiled outer cover plate enables the cooling box to safely carry other transport containers.
  • outer bottom plate and the outer cover plate of cooling boxes can cooperate with each other, but to form higher stacks of several beverage and cooling boxes and other transport containers it is advantageous to use profiles, which can cooperate with each kind of transported boxes or containers.
  • the ground of the cargo compartment in the transport vehicle can also be profiled to allow cooperation with any kind of boxes and containers and it is also possible to add frames having a similar profile in the cargo compartment to allow a flexible loading with different amounts and kinds of containers even if one layer is not completely filled.
  • a first outer surface of the cool pack is in contact with the first storage chamber and a second outer surface of the cool pack is in contact with the second storage chamber, wherein the first and the second outer surfaces have different areas and/or profiles and/or thermal surface insulations.
  • This feature allows keeping the first and the second storage chamber at different temperatures during the transport.
  • the parameters area, profile, and/or thermal insulation of the cool pack allow adapting the heat transfer from the cool pack into both storage chambers to most desired requirements. For this reason, the dimensions of the surfaces and/or their thermal insulation can be designed as variable or exchangeable.
  • a cooling box according to the invention can be either unpacked with the customer and directly be returned by the transport vehicle or they can be left with the customer until it is returned by the customer to a supply center.
  • the cool pack is integrated in the cover and cannot be removed or manipulated and cannot jeopardize any person handling the cooling box. This is for example not always the case with containers cooled by separate bags of carbon dioxide snow or by separate, not integrated exchangeable cool packs.
  • the integration of the cool pack into the cover makes it desirable that the cool pack can be cooled down or exchanged by using special service tools in a short period of time, in particular 1 to 15 minutes, preferable 5 to 10 minutes, in a supply center.
  • the cool pack is designed to receive solid carbon dioxide as snow, pellets and/or an shape of blocks.
  • Different methods to produce carbon dioxide snow by expanding liquid carbon dioxide are well known and can be used to fill an integrated container as cool pack in the cover of the box with carbon dioxide snow. It is also possible to fill carbon dioxide pellets or block or bags with solid carbond dioxide in an integrated container by using special tools in a service center.
  • the coolpack contains eutectic material and has at least one coupling for coupling a supply line for a cooling fluid, which allows cooling down the cool pack via heat exchange surfaces.
  • These heat exchange surfaces can preferably be in the interior of the cool pack, but also outer heat exchange surfaces may be used.
  • the cool pack with eutectic material is integrated into the cover and can be cooled by allowing a cooling fluid to flow along heat exchange surfaces. This differs from most other concepts with exchangeable cool packs or a vaporizing cooling medium like dry ice. Depending on the eutectic material used for filling the cool pack and on the working temperature range of this material the parameters of the surfaces to keep the two chambers of the box at different temperatures can be adapted.
  • the heat exchange surfaces of the cool pack are preferably designed and dimensioned to cool the cool pack by vaporizing liquid nitrogen into the cool pack through the coupling.
  • liquid nitrogen seems to be the most appropriate means for cooling down cool packs containing eutectic material in an economic way and without complicated couplings and exhaust systems.
  • a material should be used which is solid after cooling down and remains a gel when warmed up.
  • a non-poisonous material should be used. Such materials are already available and used in exchangeable cool packs.
  • the eutectic material is according to another embodiment of the invention contained in a metallic housing and/or has metallic heat exchange surfaces, preferably the metallic housing forms at least a part of the heat exchange surfaces.
  • This embodiment can be realized for example by heat exchange pipes in the interior of the eutectic material for guiding a cooling fluid or by metallic plates, preferably ripped or otherwise profiled, along which the cooling fluid flows.
  • Internal heat exchange surfaces in the cool pack compared to outer heat exchange surfaces have the advantage that they cannot be damaged during handling and better distribute the cold in the eutectic material.
  • the described concept makes it necessary that the cooling box according to the invention can be transported by a single person like for example beverage boxes. This restricts the outer dimensions to similar dimensions or even equal dimensions as those of beverage boxes. Under certain conditions a size up to twice the size of beverage boxes may be possible. This means that the outer dimensions length, width and height of the cooling box are 500 x 300 x 55 mm +/- 20 % for each dimension separately, preferably 10 %.
  • the cool pack has a T-shaped cross section forming an inner part of the cover and perpendicular to this inner part a separating wall between the first and the second storage chamber.
  • the heat exchange surfaces between the cool pack and the storage chambers can be made larger and the lower part of the cooling box needs not to contain a structural wall.
  • stable nets on both sided may be provided to allow after commissioning to introduce the separating wall between the nets.
  • the cool pack in a first version has such a shape that it forms at least a part of a separating wall between the first and the second storage chamber.
  • This feature allows to establish the two storage chambers in the cooling box by inserting the cover with the cool pack and to cool down both storage chambers for a certain period of transport time.
  • the separating wall is mounted (possibly in variable positions) in the cooling box and can be brought into heat conducting contact with the cool pack, when the cover is closed.
  • the cooling box according to the invention is designed to being handled by a single person, having preferably a weight of less than 10 kg when empty and being designed to carry up to 15 kg as transportable load.
  • Handholds or the like should be located at outer side walls of the cooling box in such a way that they do not disturb the loading side by side.
  • the shape and dimensions of the cooling box are adapted to the shape of other transport containers, in particular usual beverage boxes, to be transported together with the cooling box in a transport vehicle.
  • the inner and/or the outer walls of the cooling box are preferably profiled to allow convection along the walls, preferably by means of vertical grooves. At the inner side this provides a smooth temperature profile by convection. At the outer side grooves make sure that each box in a transport vehicle finds almost the same ambient conditions not depending on the position in the transport vehicle.
  • the present invention also relates to a method for transporting cooled heat-sensitive products together with other transport containers from a supply center to final customers according to claim 13. This method comprises:
  • the method according to the invention allows a high throughput in a supply center as the cooling down of the cool pack, which is integrated in the cover of the cooling box can be done separately to the cleaning of the two storage chambers and the commissioning of the cooling box.
  • cleaning and commissioning may take a few minutes only the cool pack is designed to be cooled down also in a few minutes.
  • it is preferably coupled to a supply line supplying a cooling fluid for a predetermined time interval. The time interval may depend on the required amount of cooling fluid and can be controlled by usual control means. If the control means show that cooling down is completed, the coupling is disconnected and the cover can be used to close an already commissioned cooling box.
  • solid carbon dioxide as snow, pellets or blocks shall be used for cooling the cool pack, this can be done according to known methods for producing the solid carbon dioxide.
  • the carbon dioxide is stored in an integrated container in the cover of the box, preferably not accessible without service tools to avoid theft of cool packs, misuse or dangerous situations in the supply chain.
  • the filling openings should be designed such that it is not possible to manually (even for children) reach the interior of the container and to come into contact with carbon dioxide snow. It is also possible to make at least one segment in the cool pack variable concerning its dimensions to adapt it to different required amounts of carbon dioxide snow or to different cooling requirements.
  • the outer shape of the cooling box allows a safe transport in a transport vehicle similar to the known transport of beverage boxes and the like, which can form stacks, when placed on top of each other.
  • the shape of the cooling box makes it also possible to transport several of them or a mixture of beverage boxes, cooling boxes and other transport containers on a handcar or the like for distributing them to final customers.
  • the empty cooling box is then returned to the supply center either with the transport vehicle or later by the customer, where it can be cleaned to start the whole process again.
  • the cooling fluid is liquid nitrogen, which is widely and economically available and can be released into the environment or into a nitrogen network after use for cooling down the cooling packs.
  • the safest way to transport different goods in a transport vehicle is to place the heavier pieces in a lower level and to form stacks with the light weight containers on top.
  • Fig. 1 and 2 show a schematic perspective view on a cooling box 1 according to the invention with a somewhat lifted cover 12 and a longitudinal section through such a cooling box, respectively.
  • the cooling box 1 has a thermally insulating housing 7 of cuboid shape and with similar dimensions as a usual beverage box. This means in particular that the length L and the width W allow placing the cooling box 1 with a profiled outer bottom plate 20 on one or two usual beverage boxes.
  • the height H of the cooling box 1 including the cover 12 is about 500 mm +/- 20 %.
  • the cover 12 has a profiled outer cover plate 21 to safely carry further transport containers (not shown in fig. 1 ).
  • the cover 12 comprises a cool pack 13 containing a eutectic material 14 to keep the interior of the cooling box 1 cool.
  • the cool pack 13 has a T-shape forming an inner part 27 of the cover 12 and perpendicular to this a separating wall 22 between a first 9 and a second 10 storage chamber.
  • a heat exchange surface 19 is provided, in the present case formed by at least one metallic pipe for guiding a cooling fluid 17 through the interior of the whole cool pack 13.
  • the cooling fluid 17, preferably liquid nitrogen LIN enters the cool pack 13 through a coupling 15 to which a not shown supply line can be connected.
  • the cooling fluid 17 leaves the cool pack through an outlet 38 either also coupled to an exhaust line or simply open to the environment 6.
  • the size, shape and profile of the heat exchange surface 19 is designed to cool down the cool pack within 1 to 15 minutes by supplying liquid nitrogen LIN, which is released as gaseous nitrogen at the outlet 38.
  • the cool pack 13 has at least partly a metallic housing 26. When the cover 12 is closed, the cool pack 13 has a first outer surface 23 forming two sides of the first storage chamber 9 and a second outer surface 24 forming two sides of the second storage chamber 10. To maintain different temperatures in the first 9 and the second 10 storage chambers the first outer surface 24 is at least partly covered by a surface insulation 25, while the second outer surface 24 is the metallic housing 26 itself. This results in a lower temperature in the second storage chamber 10, which can be used for example for transporting deep frozen food.
  • a holder 39 for receiving an end of the separating wall 22 is mounted on the ground of the cooling box 1.
  • Handholds 36 allow a single person to transport the whole cooling box 1 and a profiled outer cover plate 21 allows to safely place further transport containers (not shown) on top of at least one cooling box 1.
  • Fig. 3 shows a similar cooling box 1 like in figures 1 and 2 in a schematic perspective view, but in this embodiment the separating wall 22 is not part of the cover 12, but belongs to the thermally insulated housing 7 or is at least inserted therein, possibly at variable positions.
  • This embodiment is preferred for cool packs filled with carbon dioxide snow as the low temperature of this cooling medium does not require large surface areas for keeping cool the storage chambers 9, 10 of the cooling box 1.
  • Fig. 4 gives an overview over the whole transport cycle when using transport boxes 1 according to the present invention.
  • a supply center 32 the first 9 and the second 10 storage chamber of a cooling box 1 are cleaned before the commissioning with products ordered by a final customer takes place.
  • fresh food in placed in the first storage chamber 9 while deep frozen food can be placed in the second storage chamber 10.
  • its cover 12 is cooled down by connecting the coupling 15 to a supply line 16, which supplies liquid nitrogen LIN as cooling fluid 17 from a tank 18 to flow through eutectic material 14 in the cool pack 13 before it is released as gaseous nitrogen through an outlet 38 into the environment 6 or an exhaust line 37.
  • the supply is maintained for a predetermined filling time T or until a certain temperature of the cool pack 13 is reached.
  • the filling may be controlled by a control circuit (not shown).
  • the cover 12 After commissioning and releasing the cover 12 from the supply line 16 the cover 12 is used to close the cooling box 1 and to establish a separating wall 22 between the first 9 and the second 10 storage chamber.
  • the closed cooling box 1 together with other such boxes is loaded into a transport vehicle 3, which receives for example a lower layer 28 of (standard) beverage boxes 29, on which the cooling boxes 1 are packed.
  • transport containers 31 for light weight goods may be packed on top of the cooling boxes 1.
  • the bottom 4 of the transport vehicle 3 should have a raster 5 with a profile to safely transport in a form locking manner beverage boxes 29 or cooling boxes 1.
  • the compartment of the transport vehicle 3 contains at least one frame 33, which can safely carry on an upper surface 34 cooling boxes 1, even if a lower layer 28 is not completely filled with beverage boxes 29.
  • the transport vehicle 3 can now deliver beverages, food and/or other articles as ordered to final customers.
  • empty cooling boxes 1 are returned (as well as empty beverage boxes 29 and transport containers 31) to the supply center 32, where the whole cycle can be started again.
  • the design of the cool pack has to be adapted for this use as can be schematically seen in Fig. 5 .
  • the cool pack 13 contains a hollow interior 41, 42, possibly divided into two or more separate (and possibly variable) sectors 41, 42.
  • At least one nozzle 40, preferable one nozzle 40 in each sector 41, 42 allows to spray liquid carbon dioxide from a tank 18 via a supply line 16 into the interior 41, 42 and to thus produce carbon dioxide snow to fill the cool pack 13.
  • This is preferably done in an automated process line 43, which allows to stop each cover 12 at a filling position, to fill it by introducing at least one filling device into a filling opening and to transport the cover 12 after filling to its next destination in the supply center 32.
  • one or more sectors 41, 42 can be filled and/or the size of the sectors 41, 42 can be varied, for example by a moving the wall between the sectors 41, 42. It should be noted that in case of using carbon dioxide snow the surfaces of the cool pack 13, as far as they can be touched by a person, have to be protected by a coating or other means to avoid injuries.
  • the present invention allows a safe and economic transport of different goods, including fresh food and deep frozen food to final customers. Especially the handling of heat-sensitive food is improved and the risks during transport and possible handling of cooling boxes by final customers are minimized.
  • the cooling boxes can either be used to unload them directly with the customer or to leave them with the customer for keeping the transported food cool for another few hours and to let the customer return the cooling box. In any case the transport cycle does not require large cooling chambers for exchangeable cool packs nor takes a long time to clean, refill and cool down the returned cooling boxes.
