Description

The invention relates to a package for storing and / or transporting thermally sensitive products, which can be used in particular as a refrigerated packaging but also as a warming packaging.

From the US 5,857,612 a package is known, which in the local embodiment of FIG. 25 has an elongated central Umverpackungsbereich, which is thin-walled and can be closed at its open ends by means of double-walled packaging lid. This packaging is intended to be used for particularly large goods and aims to protect the transportable good from damage by the double-walledness of the packaging lid.

However, this packaging is unsuitable as a transport packaging of thermally sensitive products, since the outer packaging is closed only in their end of double-walled packaging lids, whereas the central region is formed only by the thin-walled outer packaging, and accordingly a thermal insulation is not achievable here.

Another packaging is from the EP 2 514 680 A1 known. Here, the serving as a cool box packaging an outer shell and an interior of the shell surrounding all sides insulating device (referred to as insulating layer) on. The insulating device is formed from a plurality of individual insulation elements, each consisting of a fibrous material. Further, one of the insulating members is held by a holding mechanism. However, the packaging has the disadvantage that their production and assembly require many steps due to the multi-part insulation layer and the required holding mechanism and are therefore time-consuming. In addition, the fibrous composition of the insulation elements can not be optimally insulated Ensure that the material in the insulation elements is not evenly arranged and that the thermal properties of the fibrous material are location-dependent.

It is therefore an object of the present invention to propose a package, which is easier, cheaper and faster to produce, and which allows optimum insulation.

The solution of this object is achieved by a packaging, in particular cooling packaging, which comprises an outer packaging and an interior of the outer packaging surrounding all sides insulating device. The outer packaging has a jacket with a front wall, a rear wall and side walls which connect the front wall to the rear wall, and a bottom wall and a top wall. According to the invention the Dämmeinrichtung a Deckenwand- and the bottom wall side Dämmeinlage on, which are separately manufacturable components, and which can be arranged in the outer packaging on the bottom wall and under the ceiling wall. According to the invention, the insulating device of the packaging according to the invention also has another insulating insert which can be positioned in the outer packaging and which may be formed in one piece or in several parts and which comprises the side wall side as well as the front and rear wall side insulating walls. As said, these four insulating walls can be integrally formed, or, for very large packages, this insulating insert can also be divided into two parts, each comprising a side wall and the rear wall or a side wall and the front wall and inserted separately in the outer packaging can be to form in this inserted state, the insulating insert, which rests on all sides of the side walls, the front wall and the rear wall and is placed on the bottom wall side Dämmeinlage. In this arrangement, the ceiling wall side Dämmeinlage can be launched, the bottom wall side and the ceiling wall side Dämmeinlage also form Dämmwände. The packaging according to the invention is thus constructed from a few elements, which greatly facilitates the manufacturing process and the assembly of the packaging. In addition, as the insulating material for the Dämmwände a single material, such as preferably corrugated cardboard, can be used, which may also be the material of the outer packaging, so that the packaging according to the invention represents a single-material packaging, reusable and in a simple and cost-effective manner, together with waste paper recyclable and compostable.

Furthermore, this results in the advantage that the outer packaging can be used without Dämmeinlage as a simple packaging box, if insulation is not required. Furthermore, there is the advantage that the outer packaging can be combined with any of the elements of the insulation device, so that either all previously described elements of Dämmeinlage (bottom side Dämmwand, ceiling side Dämmwand and seitenrückwand- and front wall side Dämmwände) or even individual elements can be used if, for example, only a bottom insulation or only a peripheral insulation is required, so that only the corresponding elements of the insulation must be inserted into the outer packaging.

The dependent claims have advantageous developments of the invention to the content.

Thus, it is possible according to the invention to form the outer packaging as a packaging box with thin-walled boundary walls, which usually comprise a bottom wall, two side walls, a rear wall and a front wall. This body can be provided with a likewise thin-walled lid, or the lid can be divided into two or four subregions. If the outer packaging is designed, for example, as a rectangular, cuboidal packaging, two cover parts can be attached as foldable tabs to the longitudinal side forming the rear wall and pretext, while two further foldable cover tabs can be attached to the walls connecting these walls side walls.

All walls of such an outer packaging can be made of a single material, preferably corrugated cardboard.

As previously stated, the insulating walls of the insulating device can each be made of the same material as the outer packaging, so preferably corrugated board. Here, it is possible to form the insulating walls in one or more layers, depending on which insulating effect is to be achieved.

In a single-layer design of the insulating walls, this means that the insulating wall in each case has two outer boundary walls which delimit an inner space in which a middle wall arranged between these outer boundary walls is arranged. As a result, two subspaces are created, in each of which the corrugated profile of the corrugated cardboard material is arranged. This wave profile usually has a sinusoidal course and accordingly subdivides the space between one of the outer boundary walls and the middle wall into a plurality of air-filled subspaces. Likewise, the second wave profile divides the space between the middle wall and the second outer boundary wall into a plurality of separate air spaces. In the case of a rectangular plan view of the packaging, the corrugated profile usually runs parallel to the longitudinal axis of the respective insulating wall. This applies to both the bottom wall side insulation insert as ceiling wall side Dämmeinlage, as well as the peripheral insulation insert. Another orientation, in particular at right angles to the longitudinal axis, is also possible.

If the insulating effect to be increased, a plurality of insulating layers described above can be superimposed, preferably one-piece blanks are used, which in the simplest case only bent and fastened together, in particular glued, must be in order to achieve a double-walled construction.

If the corresponding insulation effect is not yet sufficient, another arrangement, either of a single-wall or a double-walled Dämmwand be glued to the first arrangement.

This in turn applies to the bottom wall side, the ceiling wall side, as well as the peripheral insulating insert of the insulation device according to the invention.

In addition to the usually sinusoidal profile of the wave profile of a conventional corrugated board, it is also possible to provide other profile profiles, if this is advantageous for insulation reasons. Conceivable here are a zigzag profile insert or rectangular courses of the profile insert.

The peripheral Dämmeinlage is preferably on the front wall, the rear wall and the side walls. Due to the precise arrangement of the insulating insert on the insides of the jacket of the outer packaging, the insulating insert also serves as a kind of reinforcement of the side walls and the front wall and the rear wall. Furthermore, an exact positioning of the product to be transported in the interior of the outer packaging is possible.

Further preferably, the insulating insert is formed from a one-piece Dämmeinlagezuschnitt, resulting in a fast and cost-effective production of the insulating insert. Thus, the entire manufacturing process of the packaging can basically be reduced to two steps by which the outer packaging and the insulating insert are manufactured. In this case, only one type of machine, namely for the formation of the blanks, is necessary whereby costs for additional machines, eg for the processing of insulating elements made of fibrous material, can be avoided.

Preferably, the Dämmeinlagezuschnitt is folded in the storage and transport state. Since the insulation insert blank takes up little space, a large supply of insulation inserts can be created for different applications.

It may also be advantageous if cooling elements are inserted into the air chamber of the ceiling wall and / or the bottom wall. As a result, the temperature of the goods stored in the package can remain unchanged even under very hot ambient temperatures.

Preferably, the outer packaging further comprises a cover plate and / or a bottom plate, whereby the ceiling wall and / or the bottom wall are covered in the final assembly state. The cover plate and / or the bottom plate serve as protection for the ceiling wall and / or the bottom wall from potential damage that might otherwise cause the insulation properties of the ceiling wall and / or the bottom wall are affected.

Advantageously, the thickness of the top wall and / or the bottom wall can be selected by changing the dimensions of the foldable parts of the first tab and / or the second tab. Thus, the packaging of the invention can be used by simple design changes for different applications.

According to a preferred embodiment of the present invention, the thickness of all insulating walls of the insulating insert is the same. This has the consequence that all Dämmwände have the same or a very similar thermal resistance.

Furthermore, the outer packaging and the Dämmeinlage are preferably made of corrugated cardboard and free of plastic and / or aluminum. The corrugated board has the advantage that it has on the one hand a high strength and on the other hand good insulation properties due to their production-related air spaces. Thus, the package may be stably formed and have additional protection for the temperature of the product stored in the package.

In a particularly preferred embodiment, the packaging according to the invention comprises a calculator, preferably in the form of preprogrammed software, which enables the user of the packaging according to the invention to calculate whether and, if so, which number of cooling packs are to be added to the packaging in order to achieve the desired cooling result.

The calculator according to the invention in this case includes factory preset and considered parameters, which can be preferably defined depending on the user.

Furthermore, the user of the packaging can enter further parameters into the calculator, which depend in particular on the respective transport. This is in particular the product weight that has to receive the packaging according to the invention. Furthermore, the time duration that the product has to spend in the packaging according to the invention can be taken into account. This period of time can be calculated, for example, from a postal code corresponding to the receiving location of the packaging.

Finally, the ambient temperature during transport can be taken into account as another parameter to be input by the customer or user of the packaging. To simplify this, this ambient temperature may be an approximate value that depends in particular on the particular season (as rough values, for example, winter or summer).

In a further particularly preferred embodiment, the bottom wall and / or the top wall of the outer packaging can be double-walled, if particularly high cooling capacities are to be achieved. The Doppelwandigkeit can be achieved here by two, for example, by means of a spacer at a distance held wall elements of the bottom wall and / or ceiling wall, which then surround an air space in the mounted state, which serves as a further insulating layer.

The following is with reference to the FIGS. 1 to 3 a package 1 according to a preferred embodiment of the present invention described in detail. Box 1 can be used to transport or store temperature sensitive products.

The packaging 1 has an outer packaging 2 according to Fig. 1A and an insulation device 10 according to Fig. 1B to 1D on. Furthermore, the packaging 1 is made of corrugated cardboard. However, it is conceivable to use other materials as well. Like from the Fig. 1 it can be seen, the outer packaging 2 has a jacket 3 with a front wall 4, a rear wall 5 and side walls 6, 7, which connect the front wall 4 with the rear wall 5, and a bottom wall 8 and a hinged ceiling wall 9. The ceiling wall 9 is integrally formed in the example. In the illustrated embodiment of the Fig. 1A the bottom wall 8 is also integrally formed. In the context of the invention, however, other combinations are also possible. Thus, for example, both the bottom wall 8 and the top wall 9 may both be formed in several parts or in one piece. The in the Fig. 1B to 1D shown damper 10 surrounds all sides in a Fig. 1 shown interior 14 'of the outer packaging 2 and protects inserted into the package 1 goods thereby both thermally and against damage.

The synopsis of Fig. 1B to 1D illustrates the construction of the Dämmeinrichtung 10th

Accordingly, the insulation device 10 comprises a in Fig. 1B schematically simplified illustrated ceiling-side Dämmeinlage, a in Fig. 1C simplified illustrated peripheral insulation insert 12 and in the representation of Fig. 1B according to the bottom-side Dämmeinlage 13 shown in accordance Fig. 1D ,

The components 11, 12 and 13 accordingly form of the outer packaging 2 separately manufacturable components that are of course adapted in their dimensions to the particular application and the dimensions of the outer packaging 2.

The peripheral insulating load according to Fig. 1C is formed integrally in the example case. In the case of large embodiments of the outer packaging 2, however, it is advantageous to construct this Dämmeinlage 12 in two pieces, the separation along the schematically illustrated dividing lines / joints T1 and T2 is carried out.

Specifically, the Dämmeinlage 12 has a front wall side insulating wall 13, a rear wall side insulating wall 14 and two side wall side Dämmwände 15 and 16, which connect the insulating walls 13 and 14 together, so that from Fig. 1C apparent box-like structure of the insulating insert 12 results. As explained above, it is possible to divide this one-piece Dämmanlage 2 into two subregions, for example along the joints T1 and T2, so that then a component, the rear wall side insulating wall 14 and the side wall side insulating wall 16 and the other component, the front wall side insulating wall 13 and second side wall side insulating wall 15 includes. These can then be inserted as separate parts in the interior 14 of the outer packaging and then form in the final assembly state again from Fig. 1C apparent box-like peripheral Dämmwandverbund.

The cover wall side Dämmeinlage 11 and the bottom wall side Dämmeinlage 13 are of course also adapted to shape and dimensions of the outer packaging 2 and constructed identically, which is also representative of the Dämmwände 13 to 16 of the peripheral Dämmeinlage 12 based on Fig. 2 will be explained.

Accordingly, in Fig. 2 Representative of all Dämmwände the packaging 1 according to the invention, the ceiling-side Dämmeinlage 11 shown. At the in Fig. 2 illustrated embodiment, this Dämmeinlage 11 four layers L1 to L4, which rest on one another, wherein for clarification of the layers L1 to L4 in Fig. 2 gaps are drawn between these layers, which simplify the clarification of the individual layers L1 to L4, wherein in a finished product, however, the layers L1 to L4 rest on each other at least substantially without a gap.

Each of the layers is constructed identically, so that reference is made below by way of example to the layer L1.

The layer L1 accordingly has outer boundary walls 18 and 19, between which a middle wall 20 is arranged. The wall 18 and 20 is in this case held by a wave-shaped spacer 22 at a distance, while the wall 19th is held by a similarly shaped wave-shaped spacer 21 to the wall 20 at a distance. The two spacers 21 and 20 extend in the longitudinal direction L (s. Fig. 1B ) of the insulating insert 11 and over its entire width B, which also made Fig. 1B is apparent.

The layers L1 and L2 are folded over each other over a bending region 23 and glued together in this state, for example.

Correspondingly, the layers L3 and L4, which, like the layer L2 in their internal structure, are constructed like the layer L1, are folded over one another over a bending region 24 and fastened in this state. The resulting packages L1 / L2 and L3 / L4 are in the in Fig. 2 embodiment also shown attached to each other, for example by a bond.

Depending on what is sufficient for a sufficient insulation effect, it is inventively possible to build the insulating walls of the package 1 according to the invention also single-layer, two-ply, three-ply or four-ply, or in extreme cases, a larger number than four layers.

In the Fig. 2 illustrated particularly preferred embodiment uses for the layers L1 to L4 commercial corrugated board. In principle, however, it is also possible to construct the layers L1 to L4 using said walls 18, 19 and 20 with differently shaped spacers, such as with zigzag-shaped spacers or with rectangular profiles.

In Fig. 3 is shown as a further feature of the packaging 1 according to the invention an insert plate 25 which is provided at the edge with flap pockets 26, 27, 28 and 29. In the folding pockets 27 and 29 also gripping openings 31 and 30 are arranged.

This plate 25 can be pressed after arranging the bottom-side Dämmeinlage 13 and the peripheral insulating insert 12 in the interior 14 'to the interior 14' placed product, wherein the tabs 26 to 29 fold over and build up a slight clamping force to the inner wall portions of the Create walls 5 to 8 of the outer packaging 2 in order to ensure the position of the product placed in the interior 14 'and, if appropriate, to serve as a supporting surface for additional cooling elements. After the arrangement of the plate 25 in the interior 14 'is the ceiling wall side Dämmeinlage 11th placed on top and the lid 9 closed, so that after the packaging 1 is ready for shipping.

In addition to the above written description of the invention is to the additional disclosure hereby explicitly to the drawings of the invention in the Fig. 1 to 3 Referenced.
