Description

Insulated packaging and the packaging containing the insulating packaging

The invention relates to a Isolierverpackung, comprising a Isolierumhüllung with at least one double-walled side wall made of a flexible material, preferably paper, wherein the side wall an outer wall and an inner wall heard, two side walls in the edge region of the Isolierumhüllung cohesively and not completely circumferentially connected to each other and As a result, the Isolierumhüllung in an unconnected part of the edge region has an opening or the opening in the Isolierumhüllung ausprägbar is. Moreover, an insulating material, preferably consisting of cellulose, can be introduced within a respective side wall and an interior can be enclosed by two side walls, which can be reached via the opening.

Furthermore, the invention relates to an outer packaging, in particular a transport container, which includes at least one such insulating packaging.

The ordering and delivery of food via mail order companies, especially in online mail order, is becoming increasingly widespread. In addition to the dispatch of non-critical, non-refrigerated foods are also sent such perishable goods, which require such cooling with increasing tendency.

For example, for the transport of foodstuffs mentioned above or for the transport of medicaments, cooling boxes, which predominantly occur in the form of styrofoam boxes, have hitherto been used. Such a box is disclosed inter alia in the utility model DE 200 18 635 U1. A more complex construction for the packaging for the transport of thermally sensitive products is disclosed in the patent DE 102 06 109 C1. A thermally sensitive material should be surrounded by several insulating layers. The product itself is directly surrounded by cooling elements, each consisting of three foil cushions. 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, an outer packaging is provided substantially in the form of a common carton. Although it is to be hoped that this multi-layer coating will show a good insulation effect overall, it is also clear that this is achieved with considerable effort. As a result, the storage of the package when empty requires a lot of space.

The generic EP 2 514 680 A1 relates to a cooling container or a cooling box for the transport of food, with an outer shell forming a carton, consisting of a lower part and a lid part, which have air pockets or air chambers for an insulating effect. The outer shell is made of materials such as plastics, polystyrene and cardboard materials, such as kraft cardboard or corrugated cardboard. In the shell, a plurality of individual insulation elements of fibrous insulating material, for example, glass wool, rock wool or cellulose, are provided, which limit a receiving space of the shell. The insulation elements carry a protective layer, which consists for example of a plastic film. Furthermore, the insulation elements can also be enclosed by a corrugated cardboard sheath, wherein the outer surface of the corrugated cardboard sheath directed in the direction of the receiving space forms the protective layer.

In WO 201 1/022458 A2 a recyclable cool box is further described, consisting of a carton and a fixable on an inner surface of the outer carton inner wall. The carton and the inner wall enclose a cavity therebetween in which a cellulosic substrate is incorporated. The cellulose substrate consists of a loose bed of paper, newspaper, cardboard or cardboard. The volume of the cooling box shown here is independent of the material to be cooled, which represents a high degree of invariability. This always requires more volume than necessary to cool. Moreover, other generic fonts relating to coolers, especially cool boxes made of paper and / or cardboard materials, known, inter alia, in the documents US 8,763,886 B2, US 8,365,943 B2 or US 2009/0078708 A1 are shown. By contrast, DE 10 201 1016500 A1 shows an insulated bag with an outer casing, an inner casing and an intermediate heat-insulating filling. The inner shell and the outer shell are made of paper, in particular recycled paper, and the filling of a paper-containing or cellulose-containing thermal insulation material, for example made of the material Isofloc®. Isofloc cellulosic fibers consist of daily paper, which is defibered during the production process. Due to the design of the insulated bag high production and energy costs and high production costs are to be expected, which is considered to be extremely disadvantageous in terms of sustainability.

Against this background, the object of the invention is to create a possibility of keeping a good to be transported, in particular perishable foodstuffs and / or medicaments, at a desired setpoint temperature for a certain time and thereby adapting it to the transportable one To ensure good, to achieve an over the prior art increased insulation effect and thereby maintain an environmentally friendly design.

This object is achieved with an insulating packaging according to the features of claim 1 and an outer packaging according to the features of claim 1 1. The further embodiment of the insulating packaging according to the invention can be found in the dependent claims of claim 1.

According to the invention, therefore, an insulating packaging, comprising an insulating casing with at least one double-walled side wall made of a flexible material, preferably paper, is provided, wherein the side wall belongs to an outer wall and an inner wall. Two side walls are cohesively and not completely circumferentially connected to each other in the edge region of the Isolierumhüllung and consequently the Isolierumhüllung has an opening in an unconnected part of the edge region or the opening is ausprägbar in Isolierumhüllung. In addition, any insulating material present in the form of fibers, preferably consisting of cellulose, is introduced within a respective side wall and, by means of two side walls, an interior can also be enclosed, which can be reached via the opening. The fiber length of the in the Side wall introduced insulating material is in this case in a range of 100 microns to 2500 microns.

The use of fibers in this length range can lead to particularly advantageous insulation properties of the insulating packaging. This may be due to the fact that optimal insulation occurs due to the fiber length in connection with the air intercalating between the fibers of the insulating material. Exceeding or exceeding the specified fiber length of 100 microns to 2500 microns can lead to a significant increase in the heat conduction and thus result in a significant decrease in thermal insulation.

It is conceivable that the fibrous insulating material completely fills the side walls of the insulating packaging or the side walls are only partially filled with the insulating material. As a result, the volume of the insulating packaging can be changed within limits and, for example, adapted to the intended content.

Meanwhile, the sidewalls of the insulating sheath could be realized such that, on the one hand, the outer and the inner walls of the sidewalls are contiguous, i. H. in one piece and thus only one chamber for receiving the Isolierma- terials is pronounced. On the other hand, the walls of the side walls, for example, in the bottom region of the Isolierumhüllung be so interconnected that each separate chambers for receiving the insulating material in the side walls are realized. The material from which the side walls of the Isolierumhüllung consist, may be preferably paper, the insulating material cellulose.

Furthermore, the side walls of the insulating packaging of a particle, both from the inside out and from outside to inside, impermeable paper, so that an introduced good against any external influences occurring as well as the insulating packaging surrounding area may be protected from the transported goods protected.

In addition, it can be regarded as advantageous that the insulating packaging likewise exerts a cushioning effect on the contained goods due to the insulating material which can be introduced into the insulating covering in addition to the insulating effect and can thus protect it against mechanical influences.

In sum, this would make the insulating packaging according to the invention particularly advantageous for the transport of refrigerated food and / or drugs as well other goods that must be kept in a certain temperature range suitable. These other commodities could be, for example, live animals, feed animals, plants, blood samples or other medical and / or microbiological samples. In addition to the dispatch of goods to be cooled, the dispatch of already prepared, ready-to-eat foods could be conceivable, which must be kept at a high temperature.

Furthermore, it can be considered as clearly advantageous if the fiber length of the introduced into the side walls, expressed as cellulose insulating material in a range of 100 microns to 500 microns, in particular 300 microns, or is.

This would make it possible that the insulation material within the sidewalls of Isolierumshüllung distributed very well, d. H. can adapt to the contour of an introduced within the insulating material advantageous and also existing cavities are minimized. This can lead to optimized isolation properties, i. H. Minimizing the heat conduction from the inside to the outside, lead. In addition, it is possible that in particular by the arrangement and the fiber structure of the cellulose an extremely advantageous acting insulation for various temperature corridors could be created.

Furthermore, the insulating packaging could be able to dissipate resulting moisture due to possibly introduced cooling elements or products to be cooled from the interior and store or bind in the cellulose. Cellulose can offer special benefits in this regard. In addition to the non-flammable nature of this, untreated cellulose is a material which is odorless, tasteless and resistant to germs. Due to their neutrality, any growth of germs that may occur will be virtually nil, which will largely preclude the growth of germs both within the insulation package and on the sidewalls. Furthermore, cellulose is designed so that no harmful particles are ejected and, moreover, with the optional use of fresh, ie non-recycled cellulose, a safe and at the same time sustainable solution in the area of migration can be created. As is extremely advantageous turns when at least one cooling element is arranged in the interior of the insulating sheath. By this arrangement, it may be possible for a good in the inner pocket of the insulating material over a period of, for example 24 hours to 48 hours in a temperature window of about -2 ° C to 10 ° C to keep.

Furthermore, instead of a cooling element as a heat element would be possible to achieve a desired heat effect according to the cooling effect of the cooling element.

Is in the interior of Isolierumhüllung an inner pocket arranged, which consists of at least two cohesively and not completely circumferentially connected individual layers, wherein the inner pocket is thus opened on one side, in each case a one-cell layer of the inner pocket adjacent to a respective side wall of the Isolierumhüllung and between the individual layers of the inner pocket a receiving area can be ausprägbar, the insulating packaging could thus be quasi as an insulated bag with an inner bag arranged in the insulated bag. It is conceivable that in the receiving area of the inner pocket to be tempered, in particular to be cooled goods, such as perishable food and / or medication may be introduced.

The arrangement of the inner pocket within the Isolierumhüllung could be extremely advantageous an air cushion between the inner pocket and the inner walls of Isolierumhüllung be present. It would be conceivable that an additional insulating effect, ie. H. For example, by reducing the heat conduction, between the inner bag and Isolierumhüllung occurs.

Moreover, a product arranged in the inner pocket could manage without further packaging materials enveloping the product and thus be in direct contact with the inner pocket, which would save resources ecologically and economically. In addition, it would be conceivable between the Isolierumhüllung and the inner pocket, for example, a sensor element, for. B. in the form of a data logger, to monitor the temperature of the goods within the inner pocket contribute. A direct contact between good and sensor element would be prevented, an accurate documentation of the hot temperature due to the proximity to the good but be given in an advantageous manner.

If the individual layers of paper, so z. B. be ensured that any leaking liquids are received during transport. Moreover, due to the continuous use of paper as the material of the insulating sheath and the inner pocket, the recyclability of the insulating packaging, sustainability and environmental protection, eg. B. compared to plastic materials can be increased. Paper turns up is simply recyclable, as plastics can not be mixed with other plastics when recycled.

Existence of the individual layers and / or the side walls of Isolierumhüllung made of paper, which is slightly creped and siliconized, then in addition z. B. the load limit of the paper, such as the tear strength, are increased. The creping of the paper can also increase the flexibility of the paper and thus facilitate wrapping of contained goods due to better conformability to contoured surfaces. In addition, it is conceivable that the adhesion of foodstuffs is minimized by the silvering, and as a result, for example, a direct contact with the inner casing becomes possible. This could be a further serving of critical foods, such as. As meat, obsolete by possibly a plastic film. Furthermore, due to the siliconization, an adhesion of introduced goods or other material besides the inner pocket can also be minimized at the insulating covering. It should be noted that the paper used could be white in color. As a result, for example, in the case of a good to be cooled, the heat input into the insulating sheath, conditionally z. B. by heat radiation, due to the more reflective surface can be reduced. In a particularly advantageous embodiment of the invention, at least one cooling element is arranged between the inner walls of the insulating sheath and the respective adjacent individual layers.

Due to the arrangement of the cooling element or the cooling elements between Isolierumhüllung and inner pocket, it is conceivable that not only takes place only a direct cooling by the cooling element, but also a cooled air cushion between Isolierumhüllung and inner pocket is generated, whereby an additional cooling effect occurs. In addition, due to the lack of direct contact of the cooling element or the cooling elements with the material to be cooled, the likelihood of dried out spots on coarse foods such as meat, the so-called freezer brand, can be minimized. The cooling element could be in the form of a cooling battery, a cooling pad, a cooling pack, a cold compress or even as a means of electrical energy, for example, generating cold element. Moreover, it is considered to be profitable if at least a part of the connected edge region of the inner pocket of the insulating packaging, in particular the entire connected part of the edge region of the inner pocket, at least with a part of the connected Edge region of Isolierumhüllung cohesively connected and the inner pocket opening side is arranged in the direction of the opening of the Isolierumhüllung. The inner pocket can thus be arranged within the Isolierumhüllung and connected to this in the edge region. In this way, a defined position of the inner pocket relative to the Isolierumhüllung may result particularly advantageous, whereby in an arrangement example of a cooling element between Isolierumhüllung and inner pocket, this does not change its position within the Isolierumhüllung. This quasi immutability of the inner pocket position can be advantageous in particular in connection with a desired, in principle almost uniform, enclosure of an inserted material inside the inner pocket with the insulating material present in the side wall.

If the height of the inner pocket in the opening-side direction is less than the height of the side walls of the insulating sheath, whereby the inner pocket thus does not extend to the opening of the insulating sheath, this is considered to be extremely lucrative since, for example, the head area of the insulating sheath is simply in direction a side wall could be folded without affecting the inside pocket. The insulating packaging could thus be virtually closed and an undesired slipping out of an introduced good can be prevented. Moreover, it is advantageous if at least one opening in the side walls of the insulating covering is pronounced in each case in the head region of the insulating covering. As a result, the packaging could also be equipped for easy carrying. In the Isolierumhüllung one or two similar openings could be present in the respective side walls in the head area. In the case of two openings, these could be arranged so that upon folding of a part of the head area about a desired folding the two openings are superimposed and a penetration example, by means of the human hand and thus a simple, one-handed, carrying is possible.

A development of the invention is characterized in that the total mass of the side walls of the Isolierumhüllung and the individual layers of the inner pocket in a range of 70 grams to 150 grams, in particular 125 grams, and / or the mass of introduced into the side walls insulating material in a range of 300 grams up

1500 grams, in particular 1200 grams, is or amounts, so this is considered to be extremely useful. By a correspondingly high weight, the insulating packaging is quasi compressed in itself and the actual to be tempered, in particular to be cooled volume, for example, compared to a non-flexible cool box, is clear reduced and could almost only correspond to the volume of the material to be tempered.

Are beyond the respective associated, each one side wall, forming outer walls and inner walls of Isolierumhüllung interconnected so that the respective side walls have a stitching, whereby in the respective side walls more chambers pronounced and further these chambers are filled with insulating material, so could slippage of the insulating minimized or even the positioning of the insulating material at certain desired locations of Isolierumhüllung be realized.

In a further advantageous development of the invention, an opening facing away from, substantially flat pronounced bottom is formed by sections of two interconnected side walls, which can be created in a profitable manner, a footprint. In addition, a deposit having the desired shape of the soil could be used to stabilize the soil in terms of its shape. The insert should be arranged for this purpose in the interior of Isolierumhüllung and be in contact with the ground. The shape of the soil itself is virtually arbitrary. It is possible, inter alia, a substantially circular or elliptical, but also a rectangular or polygonal floor.

A highly profitable embodiment is also that the average fiber length of the introduced as cellulose insulating material in the side walls in a range of 850 microns to 950 microns, in particular at about 900 microns. It is conceivable that the incorporated cellulose consists of a mixture of fibers of different lengths, the composition resulting, for example, from the fact that in the introduced cellulose insulating material less than 95 percent of the fibers have a length greater than 32 micrometers, less than 35 percent have a length greater than 300 microns and less than two percent have a length greater than 2500 microns. The average fiber length could then be 900 microns.

In particular, in the composition, a high proportion of fibers having a fiber length of insulating material introduced into the side walls greater than 300 micrometers or greater than 600 micrometers is advantageous. Even a range of fiber lengths of 300 microns to 600 microns is to be regarded as extremely advantageous, since in this area almost optimal properties both in terms of insulation effect and the moisture in association with the resulting distribution of cellulose within the sidewall.

If, in addition, a coating made of a plastic, in particular polyethylene, is applied to the facing sides of the inner wall and outer wall forming the side wall, this is advantageous in that the inner and outer walls are connected to one another in a simple manner using this layer can. In this case, this connection could preferably take place in the edge region of the side wall. In addition, the application of such a plastic layer can increase the stability and, in particular, the crack resistance of the outer and inner walls and thus of the side wall.

It can also be regarded as promising if the outer wall and / or the inner wall of the side wall have a surface-extending perforation. This surface-extending multiple perforation consists of a plurality of introduced into the outer wall and / or inner wall, spaced apart and distributed over the surface of the inner wall and / or outer wall holes with a small diameter. This diameter should be less than 300 microns, especially less than 150 microns. Such a type of perforation is also known as needling or microneedling. The hole density or perforation density may differ between inner wall and outer wall. It is possible that the perforation density of the inner wall is less than the perforation density of the outer wall. However, it is also conceivable that the perforation density of the inner wall is higher than that of the outer wall. Due to the multiple perforation, it can advantageously be made possible inter alia that accumulating moisture is absorbed more quickly by the insulating material, for example cellulose, located between the walls.

In addition, an embodiment of the invention is characterized as advantageous when a single layer with the side wall of the Isolierumhüllung in the edge region of the side wall is connected at least partially cohesively and detachably. The single layer could thus be connected via an adhesive bond with the side wall, which connection is designed detachable without destroying the side wall and / or single layer. This could z. B. after a partial release of the composite cooling elements in the area between the side wall and single layer are introduced. In this context, it is possible that the individual layers of the inner pocket reach up to the opening of Isolierumhüllung and are connected cohesively and detachably in the edge region of the Isolierumhüllung with the Isolierumhüllung. Moreover, according to the invention, an outer packaging, in particular a transport container, is provided, which contains at least one insulating packaging according to the invention. This allows a simpler transport through a stable outer packaging, which z. B. pronounced as cardboard, are designed. Moreover, furthermore, more than one insulating packaging may also be contained in the outer packaging. This could be advantageous, for example, in that goods to be transported, which may not be mixed with one another, can be arranged separately from one another in the outer packaging. This could be necessary, among other things, for vegan or vegetarian nourishing people or because of religious background. In particular, the invention highlights the aspect of sustainability and includes the environmentally friendly use of resources in the fair interaction between humans and the environment.

The invention allows for various embodiments. To further clarify its basic principle, one of them is shown in the drawing and will be described below. This shows in

FIG. 1 shows a development of the insulating packaging 1 according to the invention in a sectional representation, the insulating packaging 1 having an insulating sheath 2 with two double-walled sidewalls 3. A respective side wall 3 in this case include an outer wall 4 and an inner wall 5. The side walls 3 are cohesively and not completely circumferentially connected to each other in the edge region 6 of the Isolierumhüllung 2, whereby the Isolierumhüllung 2 in the unconnected part of the edge region 6 has an opening 7. Moreover, within a respective side wall 3, an insulating material 8 made of cellulose having a fiber length of 300 micrometers is introduced, and the side walls 3 enclose an internal space 9 which is accessible via the opening 7. The side walls 3 of the insulating packaging 1 are only partially filled with fibrous insulating material 8. In the interior 9 of Isolierumhüllung 2 further an inner pocket 10 is arranged, which consists of two, in its edge region 1 1 materially and not completely circumferentially connected individual layers 12. As a result, the inner pocket 10 is open on one side. In each case one of the individual layers 12 of the inner pocket 10 adjoins a side wall 3 of the Isolierumhüllung 2. In addition, it can be seen that between the individual layers 12 of the inner pocket 10, a receiving area 13 is pronounced. It is further shown that between the inner walls 5 of the insulating sheath 2 and the respective adjacent individual layers 12 of the inner pocket 10, a cooling element 14 is arranged net.

Furthermore, the entire part of the connected edge region 11 of the inner pocket 10 of the insulating packaging 1 is integrally connected to a part of the connected edge region 6 of the insulating sheath 2 and in this case the inner pocket 10 is arranged on the opening side in the direction of the opening 7 of the insulating sheath 2.

In addition, Figure 1 shows that the height 15 of the inner pocket 10 in the opening-side direction is less than the height 16 of the side walls 3 of Isolierumhüllung 2 and the inner pocket 10 thus does not extend to the opening 7 of Isolierumhüllung 2. FIGS. 2a, 2b and 2c show a plurality of head regions 17 of the insulating packaging 1 shown in FIG.

In FIG. 2 a, in each case two openings 18 in the side walls 3 of the insulating sheath 2 are formed in the head region 17 of the insulating sheath 2. These are arranged so that the openings 18 lie one above the other when folding a part of the head area 17 about the desired folding point 21, which can be seen as a result of this folding in FIG. 2b. FIG. 2c, on the other hand, shows the head region 17 of an insulating packaging 1 shown in FIG. 1, in which in each case an opening 18 in the side walls 3 is pronounced.

Figure 3 includes a sectional view of the insulating package 1, wherein a side wall 3 and a single layer 12 of the inner pocket 10 can be seen. Here, the respectively associated, respectively the side wall 3, forming outer walls 4 and inner walls 5 of the Isolierumhüllung 2 are interconnected so that the respective side walls 3 have a stitching 19. As a result, several chambers 20 are pronounced in the respective side walls 3 and these chambers 20 continue to be filled with insulating material 8. In Figure 4, an insulating 1 is shown, which is formed by sections 22 of two interconnected side walls 3 of the Isolierumhüllung 2 an opening 7 facing away, substantially flat bottom 23 is formed, wherein the bottom is substantially rectangular shaped. The side walls 3 are in this case filled according to the figure 1 with the insulating material 8.

FIG. 5 additionally shows a sectional representation of a development of the insulating packaging 1 according to the invention. The Isolierumhüllung 2 is in this case formed of only a double-walled side wall 3, wherein the side wall 3 turn the outer wall 4 and the inner wall 5 belong. Within the side wall 3 is present in the form of fibers insulating material 8, in this case made of cellulose, introduced. Moreover, with the side wall 3, the single layer 12 in the edge region 6 of the side wall 3 cohesively and releasably connected. In the area between the side wall 3 and the single layer 12 is still the cooling element 14. In the case of Figure 6a, an insulating 1 is shown, the Isolierumhüllung 2 again in turn only by a side wall 3 pronounced, in this side wall 3 5 of the insulating material 8 introduced and a single layer 12 is connected to the side wall 3.

A conceivable application of such an insulating packaging 1 would be, for example, to roll up the insulating packaging 1, so that the insulating packaging 1 at least partially surrounds a material located therein. Developments of this Isolierverpackung 1 may have different, geometric dimensions such as length and / or width, which can be used in a modular system, for example, for lining differently shaped outer packaging in a modular system. In this case, lengths of such insulating packaging between one and two meters, in particular up to one meter and 30 centimeters are conceivable.

In the development of the insulating packaging 1 shown in Figure 6a also two predetermined folding points 21 are shown on the insulating sheath 2. In the folding around these two desired folding points 21, an arrangement of two insulating packaging 1 is possible, as shown in Figure 6b. The insulating packaging 1 are folded according to the desired drop locations 21 at right angles and have each due to a U-profile. The designed in U-shaped insulating packaging 1 are hereby rotated about its main longitudinal axis 25 at right angles to each other and arranged so that they interlock and enclose the interior 26. The insulating packaging 1 are arranged inside the outer packaging 24.

Such an arrangement of the two insulating packaging 1 in the outer packaging 24, as shown in Figure 6b, can be generated from a space-saving nesting of the two insulating packaging 1 by three handles. Such a space-saving arrangement is shown schematically in Figure 6c, in which there is a view of the edge region 6 of the insulating packaging. Two insulating packaging 1 are here nested so that an insulating 1 is arranged due to their flexible configuration in an S-shape, which is enclosed by the second insulating 1.
