Independent claims are included for the following: (1) a construction kit with a holding mechanism; and (2) a method for transporting a cooling good.

Description

The present invention relates to a refrigerated container and a method for its use. Refrigerated containers, e.g. in the form of coolers, can generally be used for transport to be cooled, in some cases, other sensitive goods. In particular, they are used for the transport of food and medicines. The present invention further relates to a method for transporting a chilled goods and a kit for a refrigerated container.

Background of the invention

So far, cool boxes, for example, for the transport of food or for the transport of medicines, mostly in the form of Styrofoam boxes are common. Such a box is for example in the utility model DE 200 18 635 disclosed.

A more complex construction for the packaging for the transport of thermally sensitive products is in the patent DE 102 06 109 C1 disclosed. A thermally sensitive material should be surrounded by several insulating layers. The estate itself is surrounded directly by cooling elements, which consist of three foil cushions each. These foil cushions engage each other so that they form a first complete envelope of the product to be transported. This innermost enclosure is surrounded by an inner box, which is made of rigid polyurethane foam panels. The inner box, in turn, is enclosed by a further coating layer. This cladding layer consists of four side plates, a bottom plate and a ceiling plate. These plates should be made of foam. As a further outer layer is an outer packaging substantially in the Form of a common box provided. Although it is to be hoped that this multilayer wrapper will generally provide a good insulation effect, it is also clear that this is achieved with considerable effort. As a result, the storage of the package from the empty state requires a lot of space. Incidentally, the materials used can only be considered environmentally friendly to a very limited extent.

The publication 26 52 354 discloses a cryogenic storage tank. This storage tank should consist of an inner vessel for receiving a good and this enclosing gas-tight outer container. The space between the inner vessel and the outer container can be evacuated. In this space fiber layer layers can be additionally provided. This concept allows the use of a variety of different fiber layers. However, the isolation effect is most likely generated by the evacuation of the cavity formed. Again, the vessel has filled and unfilled a lot of space. In addition, a design in which a vacuum can be maintained for a long time, usually both not quite inexpensive and shock-sensitive.

The present invention seeks to improve the state of the art. It should be provided a long and reliable cooling cool box. In an important aspect, this is done with manufacturing processes that usually require low investment costs. In another important aspect, this should be achieved in an ecological way. Ecological considerations concern both the cool box itself and process aspects in its manufacture and use.

Further description of the invention

The present invention relates to a refrigerated container, which can be provided, for example, in a form which is commonly referred to as a cool box. Inside, the cooling container has a receiving space. This can be, for example, cuboid or cylindrical. There is also a specially adapted form of the recording room into consideration. For adaptation additional support and cushioning means may be provided in the receiving space. It is also possible that parts of the insulation material described in more detail herein, in particular an insulation layer, can be designed so that they can assume supporting and cushioning functions for certain products.

In the context of this invention is spoken by a refrigerated container and according to a refrigerated goods, but the container is also suitable for receiving warm or hot materials (including food) and can then serve to keep warm. This is to be understood.

Outside, the cooling container is surrounded by an outer shell. This can give the cooling container any conventional form. For example, a cylindrical shape or a cuboid shape is well in question. The outer shell should be made of a solid self-supporting material. Thus, the geometric stability of the cool box can be given essentially by the material of the outer shell of the box. However, it is also possible to choose the thickness of the material of the outer shell so that the cool box contains a sufficient stability of use only by combining the outer shell with other elements. The outer shell should already offer a certain insulating effect. For this purpose it should have air pockets or air chambers. For the outer shell come as materials in principle plastics, Styrofoam and cardboard materials, such as kraft cardboard or corrugated board, in question. Air pockets or air chambers serve a preferred relationship between stability and air Isolation effect to achieve. Therefore, corrugated board is particularly well considered. In a preferred material, the material comprises 10 to 90 volume percent air chambers, suitably 20 to 80 volume percent or even 50 to 70 volume percent.

Conveniently, a double-sided laminated corrugated board. The easy printability of the outer surface of the outer shell is a relevant additional benefit of such material. A suitable Wellpapp material is the so-called B-wave, which zwichen two outer layers has a wave position with wave pitch between 5.5 and 6.5 mm and wave height between 2.2 and 3.0 mm.

In an alternative development of the invention, such materials, for example among the plastic materials, which generally have less volume percent of air chambers or even no air chambers would be suitable for use as an outer shell.

The cooling container should have an insulation layer which is formed from a plurality of individual insulation elements. The insulation elements contain a fibrous insulating material having a density of less than 100 Kg / m ³ , expediently, the insulation elements consist mainly or substantially of the fibrous insulating material. Even lower densities of the fibrous insulating material may be advantageous, for example, densities in the range of 10 to 50 or 20 to 40 Kg / m ³ . These density specifications relate to the insulation material, so for example a fibrous wool. The density of the respective fibers themselves may be higher, for example fibers with a density of 100-200 kg / m ^{3 are} useful. Suitable materials for producing a corresponding insulation layer are hemp, sisal, nettle or flax. Furthermore, glass wool, rock wool or cellulose come into consideration. The corresponding fibers can be used to produce insulation wool. Particularly advantageous, however, are fibrous Materials that contain no proteins. These have proven not only beneficial for the isolation, but also avoid hygiene problems associated with proteins.

The insulation layer is to be formed from a plurality of individual insulation elements. In this case, the insulation elements may be substantially flat. The insulation elements can thus have the shape of a cuboid whose thickness is only one fifth, one tenth or one twentieth of the mean of the side lengths. In this way, insulation elements can be made available which are easy to produce but also easy to store. In particular, they are easily stackable. The insulation elements can be used with sufficient standardization with cooling containers of different sizes.

The cooling container should also have a protective layer, which is arranged between the receiving space and insulation layer. Such a protective layer leads to additional thermal insulation. By the protective layer but can create a surface surrounding the receiving space, which is independent in their properties of the insulation material used, ie about the hemp fibers. For the transport of food, the protective layer can meet the corresponding hygienic requirements. When transporting medicines, the protective layer can be optimized for the requirements of such transport. As will become apparent from the following explanations, the cooling container is constructed so that a refrigerated goods is only in contact with the protective layer. If, for example, it is necessary to comply with stringent drug legislation requirements (organ transport requirements may also be considered), it is sufficient to optimize the protective layer for these transport tasks. The protective layer can be provided, for example, essentially by a plastic film.

In the context of the invention, it has proved to be advantageous if the insulation elements can form-fit surround the receiving space. In this case, it comes into question that the insulation elements abut each other in the interior of the outer shell accurately to abutting joints.

It is also particularly expedient if the insulation elements carry the protective layer. It is contemplated that the individual insulation elements are completely or at least partially covered by the protective layer. The protective layer can enclose the insulation elements like an envelope. The protective layer can also enclose the insulation elements in the form of tube sections (so-called flowpacks).

It is particularly useful if at least one connecting strip is formed from the material of the protective layer, which can be arranged between two insulation elements. The connection strip may be an integral continuation of the protective layer surrounding the insulation elements. It is also possible to use two (or more) connection strips per insulation element. Such a connection strip can be placed in the butt joint between two insulation elements. There he can develop a sealing effect, for example, to compensate for not quite accurate abutment surfaces in the insulation elements. In this function, the connection strip would also be referred to herein as a sealing strip. Alternatively or additionally, the connecting strip can also be arranged outside a butt joint and cover it. Advantageously, it is placed between butt joint and outer shell. In this function, the connection strip would be referred to herein as insulation strips. The connection strip is thus advantageously arranged (completely or at least partially) between each two insulation elements and is in this case wholly or partly in the region of the butt joint and can also cover it to the outside. Conveniently, the protective layer is formed by a plastic film. Because of the machines that are sufficiently available for such purposes, it is expedient to attach the protective cover around the insulation elements in the form of a tubular sheath (or a "flow pack" or "flow wrap"). At both ends, the respective tube sections are sealed in the usual way.

Alternatively, however, the insulation elements can also be enclosed by a corrugated cardboard envelope. The outer surfaces of the corrugated cardboard casings can then form the protective layer of the cooling container. Even with corrugated cardboard casings, it is easily possible to provide a connecting strip for use as a sealing and / or insulating strip, for example by means of a protruding tab.

Useful is a cooling container in which the outer shell has the shape of a two-part box. Such a box consists of a lower part and a lid part. The lower part has a bottom and surrounding side wall sections. The lid part has a lid and surrounding sidewall portions. It may be expedient to dimension the insulation elements in such a way that, when they are inserted into the lower part, they project beyond the upper edge of the lower part. With appropriate dimensioning, they can then form an insulating layer in the lid part. Preferably, this insulating layer will completely cover the side wall portions of the lid part. For this purpose, the insulation elements must be higher than the korrenspondierenden side wall portions of the base - conveniently at least 20% to 200% or 50 to 100% higher.

The invention also extends to a kit for a refrigerated container of the general and more specific embodiment described herein. It is expedient, in particular, a cooling container and a kit for this with a foldable lower part and a fold-lid part. Lower part and Lid parts can then be stored in a substantially flat configuration, in which they include no or only a small empty space compared to the receiving space (eg less than 10% of the receiving space). The unfolding is conceivable, for example, by a folding mechanism with joints. A foldable lower part and a foldable lid part can be produced particularly easily if a semi-rigid material, eg corrugated cardboard, is used as the blank material for the same. By means of corresponding weakening or folding edges, for example, unfolding from a flat configuration into a predefined large-area configuration is easily possible. According to the invention, such a kit also includes a plurality of substantially flat insulation elements, for example four or six insulation elements. It is also useful if the insulation elements are wrapped with a film. It is also expedient if the cover part of the kit or generally in the sense of this invention, the cover part of the cooling container has a holding mechanism for holding an insulating element. Such a holding mechanism can be made available, for example, by means of fold-out, preferably resiliently slightly biased, tabs.

• Aufbau des Behälterdeckelteils

The present invention can also be used in terms of a particularly ecological but also economically advantageous method for transporting a chilled goods. The method according to the invention for transporting a chilled goods comprises the following steps, preferably in the order of enumeration:

• Providing a kit
• Structure of the container base, starting from a folded delivery state
• Equipping the container base with at least one insulating element
• Equipping the container base with a refrigerated goods
• Structure of the container lid part
• Transport of the chilled goods

The loading of the container base can also be done after the construction of the container lid part. Preferably, the method also includes a final step of the partial or complete disassembly of the cooling container into individual parts, ie in the lower part, the cover part and insulating elements.

Preferably, such a method uses a kit of the type described herein and a cool box with the other features described herein. It is particularly advantageous if the insulation elements are reused in this method. For this purpose, it is expedient if the insulation elements and cooling containers have normalized sizes. The insulation elements can then be reused with a new outer shell. As a rule, the insulation elements are used with the protective cover surrounding them. However, it may also be considered to continue to use only the insulation material of the insulation elements, and to replace the protective cover, or to provide with a further protective cover surrounding the first protective cover. The reuse of upper and lower part may also be zweckmäßg in individual cases, but can also be omitted. When these parts are made of corrugated board, their delivery to conventional paper recycling is usually worth considering. For a further cooling transport, a cooling container with an unused outer shell can then be made available.

The invention also relates to a kit system for the production of refrigerated containers of various sizes and to a corresponding method. According to the invention, a kit system can be provided or used in which material for the outer shell of cooling containers of different sizes is provided. Further Isolation elements are provided. The size of the outer shells and the size of the insulation elements is coordinated so that insulation elements can be used with different outer shells. For example, if two parallelepiped outer sheaths are provided, each having smaller end faces and longer side faces, a kit system can be realized in the following manner: The side face of a smaller outer sheath can be exactly the size of the face of a larger outer sheath. It is also contemplated that the insulation elements are used in different orientations in different outer sheaths, for example, rotated 90 degrees to each other. In a preferred kit system for refrigerated containers cuboid cooling containers are used, each having six insulation elements of three different sizes. Equal-sized insulation elements are used in each case on the opposite end faces, opposite side surfaces and in the lid and in the floor. In a refrigerated container having an outer shell of different size, one or even two pairs of insulation elements in another position may then also be used.

In the context of the invention is therefore also a method in which a plurality of cuboid outer shells for coolers is combined with a plurality of insulation elements, wherein the plurality of insulation elements exceeds the plurality of outer shells by less than a factor of 3. In this way, a system of kits for refrigerated containers can be provided in the material and storage cost-saving manner.

The Fig. 1 shows some basic elements of a not yet assembled cooling container 10. The cooling container 10 consists of an outer shell 12, in which an insulating layer 14 is provided.

The insulation layer 14 is provided by a plurality of, here initially two individual insulation elements 16. The elements 16 are substantially flat, so have the shape of flat cuboid. Since the outer shell in the example shown is that of a parallelepiped-shaped cooling container, the insulation elements 16 can be comfortably inserted accurately along the inner walls of the outer shell.

Fig. 2 shows the outer shell 12, in which two insulation elements 16A and 16B have been accurately inserted. These two elements are parts of the insulating layer 14.

Fig. 3 shows a further step of assembling a cooling element according to the invention from various individual parts. The outer shell 12 is still provided in this state only by a lower part 20. This base has an open box shape. The outer shell 12 is now equipped with four visible insulation elements, which nestle against the side walls. These are the ones Isolation elements 16A, 16B, 16C and 16D. These four insulation elements abut each other flush. On its inner surface, a protective layer 18 is provided. The insulation elements project beyond the lower part 20 of the outer shell 12. They enclose a receiving space 22. In the lower part 20 with the thus positioned insulation elements 16 could be given a refrigerated goods.

Fig. 4 shows closer structural details of a suitable insulating element 16. This element may consist of a suitable insulating material, which is surrounded by a protective sheath 24. This protective sheath 24 may be provided in the approximate shape of a tubular film. The protective enclosure may include one, or as shown here, two end strips 26A and 26B. Conveniently, the end strips also serve to close the open ends of the protective sheath 24. The protective sheath thus has essentially a flat cuboid shape, but it does not have to have planar end faces, but rather may have structured end faces. The structure of the end faces may include, for example, the end strips 26 shown.

Fig. 5 shows a plan view of a prepared for receiving a refrigerated goods cooling container, as shown in a perspective view in Fig. 3 was shown. This supervision can be seen from the circulation, which describes the shell 12, which describes the shape of a rectangle. Internally abutting thereon isolation elements 16A, 16B, 16C and 16D are provided. The bottom of the refrigerating container 12 is covered with an insulating member 16E. These insulation elements 16 provide a protective layer in the direction of the receiving space of the cooling container. This is a substantially continuous protective layer, but having different sections, namely the sections 18A, 18B, 18C and 18D, which are provided by the respective insulating elements 16. However, the individual isolation elements are on all sides of the Enclosed material of the protective layer, which provide a protective sheath 24 for the insulation elements 16.

The four lateral insulation elements 16A, 16B, 16C and 16D shown each have end strips 26. Analogous to Fig. 4 For the isolation element 16D, a left end strip 26A and a right end strip 26B are shown. Within the scope of the invention, the position of these end strips 26 is relative to the butt joints 28, which result between two adjacent insulation elements. The position of the end strips is particularly well recognizable by the enlarged detail view of the upper right corner of the top view.

It has proven expedient to bend in each case one end strip in the manner of the end strip 26A in such a way that it forms an insulation strip 30. Such an insulation strip is intended to cover the butt joint to the outside, to the outer shell 12. Thus, it represents an additional insulation of the potential heat gap, which could open or open in the region of the butt joint between the insulation elements 16. It is also expedient to bend end strips, such as the end strip 26B, in such a way that it is placed as a sealing strip 32 in the butt joint between two insulation elements 16. There it acts as a sealing strip 32. The corresponding sealing strip provides additional sealing of the joint, especially if it does not cause a completely form-liquid connection of the insulation elements from all points. Since the filling material of the insulation elements, namely the insulating material in the form of hemp, is not very strong and therefore can not be assembled to quite regular cuboid insulation elements, such insulation strips 30 and sealing strips 32 have a very favorable supporting insulation function.

The Fig. 6 - 10 show now more details of the cover part 40. From the perspective view of Fig. 6 is first to realize that one Cover part 40 can be made useful from a blank 42. For example, it could be a blank made from a corrugated cardboard web. By a corresponding pattern, it is possible to produce a cover part with appropriate lateral wall sections. For example, the opposing wall portions 46A and 46C have a simple material thickness. On the other hand, in the wall portion 46B, two sheets of material of the blank are superimposed.

Fig. 7 shows how the actual cover 44 of the cover part 40 can be covered with an insulating element. The insulating member 16F completely covers the lid surface 44. So that it does not fall out of the cover under the influence of gravity, in particular when placing the cover part 40 on the lower part 20, the insulating element 16F is held by a holding mechanism. This holding mechanism may for example consist of retaining tabs 48A and 48B. Such retaining tabs may be integrally provided in the blank 42. They can be resiliently biased.

Fig. 8 shows the lid part, in which the insulating element 16F has been used accurately. The insulating member 16F is now obtained from the opposing retaining tabs 48A and 48B.

Fig. 9 shows an alternative inner part for the lid. An insulating element 16F of the known type is in this case combined with a coolant intake.
The coolant intake can be made of corrugated cardboard, for example.
Corrugated board has the necessary rigidity to make a cuboid comfortably.
The insulation element 16F may be expediently surrounded by a corrugated cardboard sleeve. But it can also be surrounded by a protective sheath in the form of a film. Between film and coolant absorption can be made for example by gluing a convenient connection. The coolant intake can be dry ice or pick up another suitable coolant. Provide circulation holes, it is expedient.

In Fig. 10 the insertion of such an insulating member 16F is shown with coolant receptacle 50 in a cover part 40. However, the provision of a coolant intake is not always necessary in the context of the present invention. It may be expedient to bring a coolant, such as dry ice, into direct contact with the item to be cooled.

In Fig. 11 Now, the placement of a cover member 40 is shown in perspective on a lower part 20. The insulating layer is already formally liquid, the lower part 20 is introduced and projects beyond the upper edge of the lower part. In this way, the insulating layer 14 can also serve as an insulating layer in the region of the wall sections 46 of the cover part. It is by the lower part 20 superior insulation layer 14 very easy to pass the cover fit, so that a seamless outer shell is formed.

The transportable cool box is in Fig. 12 shown. Lower part 20 and cover part 40 form a smooth, uniform outer shell 12. There is a butt joint between lower part 20 and cover part 40. This butt joint can be covered by a connecting band. This connecting band ensures both an even better insulation and the mechanical connection of lower part 20 and cover part 40. A commercially available adhesive tape is generally suitable as a connecting band.

Fig. 13 now shows another aspect of the invention. Standardized flat insulation elements can be made using a flow wrap machine 60 (or "flow wrap machine") which is readily available for other uses in the machine market. Such a tubular bag machine 60 initially has a supply for wrapping material 62. Only the most essential elements of the machine are discussed here. Behind the supply of the wrapping material 62 is a folding box 64th arranged. By folding box 64 side edges of the wrapping material 62 can be erected during operation. The wrapping material 62 thus moves ahead with a U-shaped cross section. In the upwardly open U individual internal parts 66 can be inserted for insulation elements. For example, these may be cuboid hemp elements. These elements approach a cross slide 68. The cross slider 68 drains portions of the filler material and simultaneously seals the ends. In this way, the insulation elements are wrapped and sealed. At the same time, the very advantageous end strips are generated by the transverse sealer 68.

Fig. 14 shows that the cooling container 10 according to the invention is not only superior in terms of economic and ecological view known concepts, but also provides an excellent cooling effect. Shown is a graph representing temperature data as curve K1 and relative humidity data as curve K2. The diagram is based on measurements on a cooling container according to the invention, in which measurement was carried out over a period of about 45 hours. After a preparation time, the measurement is read off at an hour 0 on the abscissa. At the hour 0, a temperature of about -40 degrees Celsius is measured. Over the first 10 hours, this temperature is essentially maintained. An increase over a temperature of -30 degrees, which is still very sufficient for almost all practical purposes, does not take place until after about 23 hours. After the 25th hour, there is a slow increase in temperature, but even in a time window of 45 - 48 hours, so after almost two full days, measured minus temperatures. After the first cooling, however, was not cooled over the entire series of measurements. A correspondingly favorable course is shown by measurements of the relative humidity in the cooling container, which is represented by the curve K2.

All in all, it turns out that this concept opens up new possibilities for a very efficient, environmentally and energy-efficient refrigerated transport, both with regard to the refrigerated container and with regard to the kit and the corresponding procedures.
