Description

 container

The invention relates to a container for the transport of refrigerated and / or frozen products and its use.

From EP 2 988 080 AI a container for the transport of refrigerated and / or frozen products with two separate cooling chambers for holding refrigerated or frozen products is known, wherein the cooling chambers can be closed by a common lid. In the lid two coolant chambers for receiving dry ice are integrally ¬ arranged, which are connected via fluid lines to a each other, for each other with a cooling chamber. By suitable filling or non-filling of the coolant chambers with dry ice and / or the optional closing of individual fluid lines, it is possible to achieve different cooling temperatures in the two cooling chambers over a relatively long period of time. This is particularly advantageous, are to be taken if ¬ ¬ gleichzei tig chilled and frozen products in the container.

In the container or the two cooling chambers if a uniform temperature is desired - particularly if exclu ¬ Lich refrigerated products, however, are not to be taken frozen products - if the document

EP 2 988 080 A1 proposes removing the partition wall between the two cooling chambers so that a single continuous cooling chamber with a uniform temperature is formed.

Although an embodiment of the container with removable partition is unproblematic in many cases, a removable partition can be nachtei ¬ lig in particular scenarios. If the container is, for example, filled by a first user exclusively with products to be cooled, which is why the first user removes the partition, and then sends it to a second user, the latter can not readily accept the container - in particular without the first user having given the previously removed partition or the second user having a suitable partition - for simultaneous use use chilled and deep-frozen products ¬.

Object of the present invention is to provide a container in which the disadvantages of the prior art no longer occur or only to a lesser extent.

This object is achieved by a container according to the

Main claim and use of the container according to the independent claim 10. Advantageous developments are the subject of the dependent claims.

Accordingly, the invention relates to a container for transporting cooled and / or frozen products with at least two separate cooling chambers for holding refrigerated or frozen products, wherein the access openings of the individual cooling chambers are arranged in a common plane and optionally ver ¬ closable by a common cover , wherein the lid has at least one coolant ¬ chamber for receiving coolant and starting from each of the at least one coolant chamber each at least one Fluid idleitung to the cooling chambers on the closing side facing the lid, and the lid for closing in at least two different positions the container is locatable, wherein the ending in the first position in a first single cooling chamber fluid lines in the second position do not all end in the first or a second individual cooling chamber. The invention further relates to a use of the container according to the invention, wherein the lid is arranged in the second position on the container.

In the case of the container according to the invention, therefore, the assignment of the fluid lines between the at least one coolant chamber and the at least two cooling chambers can be changed by selectively disposing the cover on the container in one of the at least two different positions. It is essential that not all fluid lines that end in the first position all in a specific individual cooling chamber, in the second position, all again in one (the same or another) specific individual cooling chamber end. For example, in a container having two cooling chambers, not all fluid lines terminating in the first position in the first chamber may end up in the second position all in the first or the second chamber; Rather, a part of said fluid lines in the first, another part in the second chamber to end. It does not matter whether the affected fluid lines emanate from a single or several different coolant chambers.

By according to the invention, the assignment of the fluid lines to the individual cooling chambers when closing the container with the lid can be changed by the choice of position with which the lid is placed on the container, an extended compared to the prior art flexibility ¬ visibly reached the temperature in the individual cooling chambers and in particular the temperature difference between the individual cooling chambers. With a suitable arrangement of the fluid lines, for example, all fluid lines emanating from a coolant chamber can end in the first position of the cover in a single first cooling chamber, while the fluid lines in a second position are each halfway in the first cooling chamber. chamber and a second cooling chamber. In the first position, it is then for instance possible in the first cooling chamber by contained in the coolant chamber refrigerant one for low ¬ cool sufficiently low temperature (for example from -24 ° C to -. 20 ° C). To reach (the second cooling chamber may cooled in this case via a possibly existing second coolant chamber), while in the second position via the coolant contained in the coolant chamber, both cooling chambers can be cooled to a sufficient temperature for cooling (eg. 5 ° C to 7 ° C) (a possibly existing second

Coolant chamber can remain free of coolant). In the latter case, due to the halfway division of the fluid lines, it can be assumed that the same temperature is established in both cooling chambers. A removable partition, as provided in the prior art, is not required for this purpose. Rather, it is preferred if the configuration of the cooling chambers is immutable, that is, in particular no optionally removable configuration elements, such as, for example, partitions, are provided. It is preferred if two fluid lines are provided starting from at least one Kühlmit ¬ middle chamber at least, and all ends of the at least one coolant chamber outgoing fluid conduits in the first position of the lid during closing in the same cooling medium chamber and in the second position of the lid during closing of a

Coolant chamber outgoing fluid lines), preferably in equal parts, in at least two different cooling chambers end. As already stated, it is further preferred if the number of fluid lines ending in the second position in the different cooling chambers is the same in each case. Two of the at least two positions of the lid are preferential ¬ as an angle smaller 180 ° angle different positio ¬ NEN. The angle is formed around an axis perpendicular to the common plane of the seed ¬ access openings. Further preferably, the angle between the two positions is an integer multiple of an integer part of 180 °

(ί x 180 ° // with i, j EN > 0 ). More preferably, the angle between the two positions is 90 °.

The outer contour of the lid is preferably symmetrical about at least one plane perpendicular to the common plane of the access openings. By a corresponding symmetry - which relates to the lid in the arranged state on the container - can be easily ensured that the lid can be fastened in at least two different angular positions on the container. The angular position of the symmetry ¬ plane changes between the two positions in this case according to the angle between the angle-different positions. The internal structure of the cover - in particular, the Substituted ¬ staltung the coolant chambers and the fluid conduits - not to the plane of symmetry for the outer contour, however, normally symmetrical.

It is particularly preferred if the cover has the shape of a re ¬ lar polygon, preferably a square, or a circle. A corresponding shape meets the requirements described above for the surface symmetry and is easy to manufacture.

It is preferred if the cover two or more refrigerant ¬ chambers, preferably a plurality of coolant chambers corresponding to the number of cooling chambers, wherein preferably at least immediately adjacent coolant chambers are fluidly interconnected. By one of the number of Cooling chambers corresponding number of coolant chambers is provided, it is possible that at least one position of the De ¬ cube each cooling chamber, a coolant chamber is assigned directly such that all emanating from a coolant chamber fluid lines each end in a specific cooling chamber. By individually filling the coolant chambers with coolant, the temperature in the respective associated cooling chamber can be adjusted individually. If frozen products are to be taken up in a first cooling chamber, only cooled products in a second cooling chamber, then the coolant chamber assigned to the second cooling chamber can also remain free of coolant. The second cooling chamber is then indirectly "co-cooled" due to the fluid communication between the coolant chambers via the coolant in the cooling chamber associated with the first cooling chamber.

It is preferred if means for selectively closing at least one of the fluid lines and / or one of the fluid connections between two coolant chambers are provided. In particular, if more than one fluid line between a coolant chamber and a cooling chamber or more than a fluid connection between two coolant chambers are provided, by selectively closing at least a portion of the fluid lines or fluid connections, the heat exchange between the individual chambers can be influenced. The means for selectively closing may be formed as a plug. But it is also possible that as a means for selectively closing the fluid lines or fluid connections and gate valves are provided in at least a portion of the fluid lines o- fluid connections.

The container and / or the lid are preferably made of thermally insulating material, preferably of Schaumpolysty ¬ rol. This allows the heat exchange with the environment of the container and its chambers with each other - except the expressly desired heat exchange through the fluid lines and fluid connections - be reduced.

It is preferred if the coolant chambers are designed to accommodate solid and sublimable coolant, in particular dry ice. Dry ice sublimates at -78.48 ° C. It bie ¬ therefore tet sufficient cooling properties and leaves no liquid melt product, which would have to be captured or held separately from the to be cooled or be frozen products. To explain the inventive use of the container according to the invention, reference is made to the above statements.

The invention will now be described by way of example with reference to an advantageous embodiment with reference to the accompanying drawings. Show it:

Figure la, b: schematic representations of an Ausführungsbei ¬ game of a container according to the invention with two different positions of the lid.

FIG. 1 schematically shows an exemplary embodiment of a container 1 according to the invention for transporting cooled and / or frozen products.

The container 1 comprises two from each other by a fixed and in particular not removable divider 2 ¬ separate cooling chambers 3.1, 3.2 to receive the cooled and / or deep-cooled products. The products can thereby be taken over Zugriffsöff ¬ voltages 4.1, 4.2 placed in the cooling chambers 3.1 3.2 or from these. The access openings 4.1, 4.2 are arranged in a common plane at the top of Be ¬ container 1. The container 1 or the two cooling chambers 3.1, 3.2 can be closed by the common cover 10 optional. For this purpose, the lid 10 is arranged in a suitable position on the container 1. The outer contour of the lid 10 corresponds to a square. Both lid 10 and Behäl ¬ ter 1 are made of foam polystyrene.

The lid 10 includes two coolant chambers 11.1, 11.2 for selectively receiving of dry ice as the cooling means (not constitute ¬ provided). The accessibility of the coolant chambers 11.1, 11.2 to the charging of refrigerant is ensured by the removable Cover B ¬ ckung 12 of the lid 10 degrees.

The two coolant chambers 11.1, 11.2 are interconnected by a fluid connection 13. In addition, start from each coolant chamber 11.1, 11.2 fluid lines 14.1.1, 14.1.2, 14.2.1, 14.2.2, facing the container 1

Side of the lid 10 lead so that they end in one of the Kühlkam ¬ mers 3.1, 3.2, when the lid 10 is disposed on the container. The latter is illustrated by the dashed and dotted lines in FIG. 1a, b. The lid 10 can be arranged in two 90 ° about an axis perpendicular ¬ right to the level of the access openings 4.1, 4.2 angle different positions on the container 1. The angle between the two positions is 90 °. In Figure la, the first position of the lid 10 is shown, in Figure lb, the second.

In the first position, all the fluid lines 14.1.1, 14.1.2 of the one coolant chamber 11.1 end in the one cooling chamber 3.1; All fluid lines 14.2.1, 14.2.2 of the other coolant chamber 11.2 end in the other cooling chamber 3.1. In the first position of the lid 10, it is so possible, for example, by filling the one coolant chamber 11.1 with dry ice for Deep freeze sufficiently low temperature (eg. From -24 ° C to -20 ° C) in the first cooling chamber 3.1 to achieve. If the other coolant chamber 11.2 is likewise filled with dry ice, a temperature suitable for deep cooling is also established in the other cooling chamber 3.2. If the other coolant ¬ chamber 11.2 contrary empty (cool-free), the cooling of the other cooling chamber 3.2 is done merely indirectly via a coolant chamber 11.1 through the fluid interconnect 13, the other coolant chamber 11.2 and the fluid lines 14.2.1, 14.2.2, so that in the other cooling chamber 3.2 sets a temperature suitable for cooling, but not for freezing.

In the first position of the cover 10 shown in Figure la, it is thus possible either to cool both cooling chamber 3.1, 3.2 to a suitable temperature for freezing or one of the two cooling chambers 3.1 to a temperature suitable for freezing, the other cooling chamber 3.2 but only to cool a suitable temperature for cooling. Cooling of both cooling chambers 3.1, 3.2 to a temperature suitable for cooling, but not for freezing, is in the first position according to FIG. due to the not removable

Partition 2 - at least not possible with reasonable effort mög ¬ Lich.

However, the same can readily be achieved in the second position of the lid 10 shown in FIG. 1b. In this, rotated by 90 ° relative to the first position second position of the lid 10, ends one half of the fluid lines 14.1.1 of a coolant chamber 11.1 in the one cooling chamber 3.1, while the other half of the fluid lines 14.1.2 same coolant chamber 11.1 in the other cooling chamber 3.2 ends. This also applies analogously for the Fluidlei ¬ obligations 14.2.1, 14.2.2 of the other coolant chamber 11.2. Now only one of the two coolant chambers 11.1, 11.2 with Dry ice filled, while the other coolant chamber 11.2, 11.1 remains free of coolant, the two cooling chambers 3.1, 3.2 are both cooled to a temperature suitable for cooling products tempera ture .
