Description

The invention relates to a Isolierverpackung, comprising a Isolierumhüllung with two double-walled side walls made of a flexible material, preferably paper, one side wall an outer wall and an inner wall listened to the side walls in the edge region of the Isolierumhüllung cohesively and not completely circumferentially connected to each other and As a result, Isolierumhüllung in an unconnected part of the edge region has an opening. Moreover, within a respective side wall, an insulating material, preferably made of cellulose, introduced and the side walls include an interior, which is accessible 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, refrigerated boxes, which predominantly occur in the form of styrofoam boxes, are customary for the mentioned transport of foods or else for the transport of medicaments. Such a box is among others in the utility model DE 200 18 635 U1 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, 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 refrigerated container or a cool 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 envelope, wherein the outer surface of the corrugated cardboard envelope, which is directed in the direction of the receiving space, forms the protective layer.

In the WO 2011/022458 A2 Furthermore, a recyclable cool box is 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 of paper and / or cardboard materials, known, inter alia, in the writings US 8,763,886 B2 . US 8,365,943 B2 or US 2009/0078708 A1 are shown.

The DE 10 2011 016 500 A1 shows, however, an insulated bag with an outer shell, an inner shell 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 fiberized 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 invention has the object to provide a way to keep a good to be transported, especially perishable food and / or medicines for a certain time at a desired target temperature while adaptability to the transported goods to ensure that achieved 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 11.

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 sheath with two double-walled side walls made of a flexible material, preferably paper, is provided, wherein a side wall of an outer wall and an inner wall heard. The side walls are cohesively and not completely circumferentially connected to each other in the edge region of the insulating sheath and consequently the insulating sheath has an opening in an unconnected part of the edge region. Moreover, within any respective sidewall, any fibrous insulating material, preferably cellulose, is incorporated and the sidewalls further include an interior accessible through the opening.

The fiber length of the insulating material introduced into the side walls in this case is in a range of 100 micrometers to 2500 micrometers.

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. be present in one piece and thus only one chamber for receiving the insulating material 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 as other goods that must be kept in a certain temperature range, are 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 shipment of goods to be cooled could also be the shipment of already prepared, ready-to-eat foods 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 side walls of Isolierumhüllung extremely well distributed, ie can adapt to the contour of an introduced within the insulating material advantageously and Moreover, existing cavities are minimized. This can lead to optimized insulation properties, ie the minimization of the heat conduction from the inside to the outside. 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 an optional use of fresh, d. H. non-recycled cellulose can be a safe and sustainable solution for migration.

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 to keep 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.

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 inside the 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 single layer of the inner pocket adjacent to a respective side wall of Isolierumhüllung and between the individual layers the inner pocket ausprägbar a receiving area, 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 through this air cushion, an additional insulating effect, d. 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 the inner pocket made 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 out to be easy to recycle because plastics, on the other hand, can not be mixed with other plastics when recycled.

Existence also the individual layers of the inner pocket 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 else be minimized other material in addition to the inner pocket and the Isolierumhüllung. 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 of the inner pocket.

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 the formation of dried out spots on perishable 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, integrally connected at least to a part of the connected edge region of the Isolierumhüllung and the inner pocket opening side in the direction of the opening of the Isolierumhüllung is arranged. 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 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 Isolierumhüllung, so this is considered to be extremely lucrative, as a result, for example, the head of the Isolierumhüllung simply in the direction of 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 to 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 significantly reduced and could almost only correspond to the volume of the material to be tempered.

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

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 are not allowed to be mixed with one another can be arranged separately 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.
