Definitions

  • the present invention relates to a thermal container, which has at least one flat back cushion and a flat front cushion extending in another plane above the back cushion, which are connected to one another on opposite side edges and on a further side edge of the thermal container, are formed in one piece or via a connecting piece merge into one another, so that a cavity is formed between the back cushion and the front cushion, the back cushion and the front cushion each being formed from at least one bag or at least one compartment and a fibrous material located in the at least one bag or the at least one compartment, wherein the fibrous material has a stack of a plurality of individual layers of creped fibrous material lying one above the other.
  • the well-known thermal container has the advantage that it can be recycled in an ecologically safe manner due to the fibrous material predominantly used for this purpose.
  • the publication DE 20 2019 003 407 U1 describes packaging made of corrugated cardboard for holding and/or transporting temperature-sensitive products.
  • the corrugated cardboard is folded into a cuboid-shaped cardboard box, the side walls of the cardboard box each being formed by two spaced-apart walls, between which a thermal insulating material is accommodated.
  • the thermal insulating material can be, for example, a tubular bag containing shredded paper.
  • Such a thermal container is used to maintain the temperature of a packaged item placed in the box over a certain period of time.
  • the thermal container allows the cooling of the packaged goods placed therein, such as foods to be kept cool, medicines or blood supplies, to be maintained over a specific time in a specific temperature window.
  • the known thermal container is relatively complex to produce.
  • the size and shape of the tubular bag must be precisely adapted to the cuboid interior formed between the walls of the side walls and the tubular bag must then be fastened on the inside with an adhesive. This is difficult because the paper scraps slip in the tubular bag.
  • the walls of the side walls must be relatively close to one another. Accordingly, only a limited amount of paper shreds can be accommodated between the walls, so that the thermal insulation effect of the cardboard side walls filled with the paper shreds is only slightly higher than that of conventional cardboard side walls.
  • a thermal container which has at least one flat back cushion and a flat front cushion extending in another plane above the back cushion, which are connected to one another on opposite side edges and on a further side edge of the thermal container, are formed in one piece or via a connecting piece merge into one another, so that a cavity is formed between the back cushion and the front cushion, wherein the back cushion and the front cushion are each formed from at least one bag or at least one compartment and a fibrous material located in the at least one bag or the at least one compartment, the fibrous material having a stack of a plurality of individual layers of creped fibrous material lying one above the other, solved, wherein the fibrous material further has at least one non-separately wrapped tangled layer of loose paper shreds and/or hemp shreds arranged between two of the individual layers, which are formed from disordered fibers and whose crepe height is in each case ⁇ 0.3 mm and ⁇ 1 mm .
  • the thermal container according to the invention is particularly suitable as a cool bag.
  • the at least one object whose temperature is to be maintained can advantageously be introduced into the cavity formed between the back cushion and the front cushion connected thereto.
  • the cavity can then be suitably closed.
  • the creped individual fiber layers of the back cushion and the front cushion in themselves bring about a particularly advantageous thermal insulation of the at least one object placed in the thermal container from the environment. This is achieved in particular by the air pockets or air spaces formed between the individual layers of creped fiber material lying one above the other. Due to the creping of the individual layers, each of the individual layers has a number of mountains and valleys, with air collecting in the valleys. Since the creping is never identical from individual layer to individual layer and the individual layers are not stacked on top of each other or pressed into each other with precision, the valleys of the individual layer above do not fit into the valleys of the individual layer below, or do not fit completely into the valleys of the individual layer below, so that In any case an air gap is maintained.
  • a random layer of paper shreds and/or hemp shreds i.e. a layer of disordered paper shreds and/or hemp shreds, is arranged at least between two of the creped individual layers.
  • the paper shreds are individual paper elements that are not connected to one another to form a closed layer, or the hemp shreds are individual paper elements, not to each other are hemp elements connected to a closed layer, for example in the side walls of the document DE 20 2019 003 407 U1 If the thermal container described slips, and which in the present invention are not held together separately by a bag or the like, the paper shreds and/or the hemp shreds surprisingly remain largely in their respective positions between the individual layers in the present invention.
  • the paper and/or hemp scraps are disordered, i.e. H. they have a wide variety of orientations within the confusion. They can therefore lie on top of each other and/or form balls and/or cantilever out in the direction of the adjacent creped individual layer.
  • each of the individual layers preferably has a crepe height of ⁇ 0.3 mm, preferably ⁇ 0.4 mm, particularly preferably ⁇ 0.6 mm, in one embodiment of 0.65 mm. It is therefore a so-called high crepe.
  • either 4 or 8 of the creped individual layers are stacked on top of each other without interlayered paper and/or hemp shreds, i.e. stacks of 4 or 8 are formed, with a layer of the paper between each two of the stacks of 4 or 8. and/or hemp snippets is arranged.
  • the thermal container has 16 creped individual layers with one or three layers of paper and/or hemp shreds.
  • the bag or compartment also has a protective function for the fibrous material contained therein.
  • the fibrous material used in the present invention for both the creped individual layers and for the paper shreds which can be a primary fibrous material, such as a pulp, a wood pulp or a semi-pulp, and / or a secondary fibrous material, such as a fibrous material obtained from waste paper, as well as the Hemp used for the hemp snippets has the advantage that it is a natural material that is harmless to the environment, is easily recyclable and in itself has low heat conduction and therefore good thermal insulation properties.
  • At least the two individual layers that lie on both sides of the respective layer of paper and/or hemp shreds are different from paper or those in the publication DE 20 2019 003 407 U1 used corrugated cardboard, made of disordered fibers. These individual layers, which are also creped, therefore have a higher surface roughness than paper or corrugated cardboard and therefore hold the paper and/or hemp shreds particularly well.
  • the design of the fibrous material used leads to an advantageous softness and voluminousness, which ensure that the packaged goods can be safely stored and transported in the thermal container.
  • the thermal container according to the invention can be easily stacked, but can also be used as a shopping bag.
  • a coefficient of static friction existing between one of the individual layers and a layer of the paper from which the paper shreds are formed is at least a factor of 1.1, preferably at least by a factor of 1.25, particularly preferably at least by a factor of 1.34, greater than the coefficient of static friction that exists between two layers of the paper from which the paper shreds are formed.
  • the paper scraps stick particularly well to the creped individual layers and therefore hardly slip.
  • the paper scraps stick better to the creped individual layers than they do to cardboard, for example, as in the printed publication DE 20 2019 003 407 U1 used to form the side walls of the packaging would adhere.
  • the paper shreds adhere better to the creped individual layers than they do to the tubular bag made of polyethylene film into which they are placed in the publication DE 20 2019 003 407 U1 were introduced, would be liable.
  • the coefficient of static friction between a layer of the paper from which the paper shreds are formed and one of the creped individual layers used in the present invention is at least a factor of 1.9 greater than the coefficient of static friction between a layer of paper , from which the paper scraps are formed, and that in the publication DE 20 2019 003 407 U1 polyethylene film used.
  • the coefficient of static friction between two layers of the paper from which the paper shreds used in the present invention are formed is on average 0.4, under the same measurement conditions the coefficient of static friction in the present invention is between one layer the paper from which the paper shreds are formed, and one of the creped individual layers at least 0.5, preferably at 0.55 and particularly preferably above 0.6.
  • the individual layers of the creped fiber material have a creping factor of at least 40%, in a special embodiment of 44%.
  • the latter creping factor corresponds to an elongation of 80%.
  • the at least one bag in the present invention is made of a fleece made of thermoplastic material, it offers good moisture protection for the fibrous material lying therein, which has good absorbency. This is particularly the case if the fleece is a polypropylene spunbond.
  • the at least one bag encloses the fibrous material in a tube-like manner.
  • the side edges of at least one bag can also be sewn.
  • the at least one bag or the at least one compartment of the back cushion as well as the at least one bag or the at least one compartment of the front cushion are made of paper. This means that the entire thermal container is made of ecologically recyclable material, namely paper and fiber material.
  • the at least one bag or the at least one compartment of the back cushion as well as the at least one bag or the at least one compartment of the front cushion are formed by an inner paper bag inserted into an outer paper bag, in each case the fibrous material is located between an outside of the inner paper bag and an inside of the outer paper bag.
  • the inner paper bag is therefore inserted into the outer paper bag and at least on the front and back of this embodiment of the thermal container according to the invention, the fibrous material is inserted between the material of the inner paper bag and the material of the outer paper bag.
  • the respective packaged goods that typically need to be kept cool can then be placed in the inner paper bag.
  • the inner paper bag and the outer paper bag are connected to one another, including the fibrous material. This means that the internal fibrous material cannot slip out of the space between the outer paper bag and the inner paper bag. This also means there is no risk of the packaged goods slipping into the space between the outer paper bag and the inner paper bag.
  • the thermal container according to the invention is particularly ecologically valuable if the creped fiber material is made from cellulose wadding, which is made from at least 90% recycled waste paper with waste paper qualities in accordance with DIN EN 643.
  • the paper shreds are made from shredded or chopped paper or the hemp shreds are made from shredded or chopped hemp.
  • shredded paper can be usefully reused for data protection reasons.

  • this connection can be made alone or in combination with the seams 16, 17 by gluing and/or squeezing the material.
  • the back cushion 2 and the front cushion 3 are formed from the same material web in the form of a bag band. Therefore, the back cushion 2 is formed in one piece with the front cushion 3 on a further side edge 6 of the thermal container 1.
