Description

Technical area

The invention relates to a transport box for temperature-sensitive goods with multiple containers and cooling elements.

State of the art

The transport of temperature-sensitive goods places high demands on logistics. Especially drugs and also many fresh vegetables such as fruit or other perishable goods need a constant temperature during the entire transport route from the place of origin to the destination. A continuous cold chain through, for example, vehicles can often be difficult or insufficient to ensure.

In addition, when a transhipment from one means of transport to another, the goods usually for shorter or longer time of the local outside temperature, if necessary, a sun exposure is exposed. This is all the more true if, due to logistical bottlenecks, the goods have to be stored for several hours or even days in a non-tempered room. As a result, the cold chain is endangered, and it can quickly lead to spoilage of the goods.

In this context, refrigeration units are already known with mostly a relatively expensive cooling liquid, such as paraffin, salt solutions, glycol, alcohol or other suitable liquids, which are placed in transport boxes with multiple containers. These refrigeration units should ensure that the goods to be cooled remain tempered. However, such cooling methods not only have the disadvantage that their cooling liquids are relatively expensive, but that their loss, no matter what reason, refilling the units with another cooling liquid is not readily possible because the cooling properties of different types of liquids are different.

Also, it is often necessary that the cooling elements to a very low temperature, for example, well below -20 ° C, must be cooled down, but this is not possible with commercial refrigerators. As a result threatens just in case of unforeseen delays interruption of the cold chain and thus spoilage of the temperature side to be protected goods.

Object of the invention

The invention is therefore an object of the invention to provide an inexpensive transport packaging or a transport box with cooling elements, which ensures a cooling of temperature-sensitive goods for a long time at a constant temperature.

Solution of the task

The object is solved by the characterizing part of claim 1.

Advantages of the solution

This object is achieved in a simple manner in that the transport box has a plurality of nested container, between which at least partially the cooling elements can be inserted. It is particularly expedient that is used as coolant for the cooling elements tap water or service water without suspended particles, which can be preferably cooled to -20 ° C or even lower and is inexpensive.

It is expedient if the transport box has at least three nested container, which are formed by an outer first container, a middle second container which is positively inserted into the first container, and an inner for receiving the temperature-sensitive goods serving third container , wherein between the second and third container, at least partially, the cooling elements can be inserted.

Alternatively, it is also possible that the transport box from an outer first container, a middle second container and an inner for receiving the temperature-sensitive goods serving third container is formed, in which case between the first and the second and the second and the third container each, the cooling elements are at least partially inserted.

According to the present invention, the first, second and third container should consist of a thermally insulating material, wherein it is expedient that the outer first container has at least two layers, of which in turn the outer layer consists of a deformation-stable material Metal or a shock-repellent plastic.

Depending on the desired intensity of cooling, the cooling elements may be provided along the longitudinal sides of the second and / or the third container or envelop them completely.

Finally, it is particularly useful when the inventive transport box for empty transport zusammensteck- and / or collapsible or foldable formed.

Further advantageous embodiments of the invention will become apparent from the following description, the drawings and the claims.

Brief description of the drawings

[0015] FIG. <Tb> FIG. 1 <SEP> in perspective view an outer first container which simultaneously embodies a transport box according to the invention, <Tb> FIG. 2 <SEP> the transport box according to FIG. 1, in which the upper half of the outer first container is removed and in the lower half of which a middle second container is inserted in a form-fitting manner, <Tb> FIG. 1, in which cooling elements are partially inserted both between the outer first and the middle second containers, and an inner third container is provided within the middle second container, which is enveloped by a circulating cooling element and <Tb> FIG. 4 <SEP> an open view of the transport box according to FIG. 3, which is shown rotated by 90 °.

Ways to carry out the invention

As can be seen from FIGS. 1 to 4, in a transport box according to the invention, three rectangular containers are nested, starting from an outer first container 1 in this a middle second container 2 is fitted and in turn, this is an inner third container 3 is provided, in which then ultimately a temperature-sensitive product is stored. In the container 3, a small fourth container may also be provided, depending on the desired cooling time.

Cooling elements can be inserted between the containers 1 to 3, either in some areas as quilt-like plates, denoted by 4, and / or as quilting pad-like mats, denoted by 5, with which an envelope of the respective container is then possible, as in Fig. 3 shown.

In the cooling elements 4 and 5 is in the present embodiment tap water, which can be cooled with a commercial freezer to a temperature in a preferred temperature range of + 5 to -20 ° C.

In Fig. 2 is shown as a first embodiment that the middle second container 2 is only positively inserted into the outer first container 1, without the interposition of a cooling element. Whereas in FIGS. 3 and 4 the cooling elements 4 on the longitudinal sides are inserted between the outer first container 1 and the middle second container 2 as a second embodiment, whereas the quilting-like cooling element 5 in the form of a mat is arranged so that it encased inside third container 3.

The containers 1 to 3 are made of a thermally insulating material, wherein the outer first container 1 has two layers, namely in addition to the heat-insulating inner layer is still an outer shock-repellent layer of metal provided, with a correspondingly hard plastic is also possible. In this case, it has been shown that considerably higher stability requirements can be imposed on such a transport box, which, however, also increases the overall weight. On the other hand, the shock sensitivity increases.

If losses of coolant occur, they can be easily done by refilling with any clean water such as drinking water. It is important here that the water is freed from possible suspended particles, which can be done for example by filtering using commercially available filters, as they are known for coffee or tea drinks. Special hygiene standards for the cooling liquid are not to be considered. For refilling and draining the cooling liquid, the cooling elements 4 and 5 have special filler neck 6, the steppkissenartigen pad, referred to with 7, fluidly communicate with each other.

The transport of the empty transport boxes is facilitated by the individual containers 1 to 3 zusammensteck- and / or zusammenleg- or be formed collapsible, which in addition to the space transport thereby space and weight can be saved by the water as a coolant before the empty transport simply drains and at the loading place refills the cooling elements with water and cools down to the desired temperature.

The zusammensteck- and / or collapsible or collapsible container 1 to 3 are each rectangular in shape and consist essentially of a plurality of plate-shaped parts, the connection with each other via a conventional tongue and groove connection, indicated at 8, and / or a suitable joint connection, indicated at 9 and 10, can take place (Fig. 2).

Industrial Applicability

The inventive transport box is particularly suitable to transport temperature-sensitive food or medicine with an aircraft, a ship or overland, for which purpose the means of transport advantageously do not need to have special refrigerators. At the same time, this ensures that the cold chain is not interrupted in countries with relatively high temperatures and inadequate or unsafe power supply.

The advantageously used in the present invention, the cooling elements 4 and 5 need only be filled with tap water as a cheap coolant and cooled down depending on the application and the desired temperature.

For this purpose, commercial freezers can be used with which a cooling down to a preferred temperature range of + 5 ° C to -20 ° C is easily possible.

Finally, by the multiple layers of containers 1 to 3 and boxes on the one hand and the cooling elements 4 and / or 5 on the other hand in the remaining interior, which serves to hold the cargo to be cooled, over a long time (at least 12 hours) one ensures constant temperature, and without that it requires an interim replacement of the cooling elements 4 and / or 5. This period allows a transport of temperature-sensitive goods in remote areas, without having to cool the inventive transport or refrigerated transport box consuming from the outside.
