Packaging, in particular for foodstuffs and luxury items.

The invention relates to inserts and collars for packaging

the contents of the package, especially food and luxury goods, against

to preserve undesirable influences.

In conventional packaging made of plastics, paper, cardboard, etc. who the products filled, stored, transported, partially emptied with leftovers that are sensitive to external influences react. Influences can be: cold, heat, moisture, dust, shock, impact, etc.

Such products are frozen foods, ice creams, milk shakes that are packaged cold or poultry, meat products, hamburgers, cheese burgers, sandwiches etc. that are packaged warm (e.g. in drive-in establishments). Manufacturers and sellers recommend wrapping the products in lines to keep cool products cool or warm products warm. Some layers of newsprint insulate against cold and heat - albeit only to a limited extent - because there are layers of air between the individual newspaper sheets.

Now we know inserts made of insulating material in packaging:

Claims (2)

a layer of insulating material against the effects of temperature, a Söhtht insulating material against mechanical effects, a layer of insulating material against physiological effects and then other, additional layers against further effects. Other effects can also be, for example, radiation effects. According to the invention, "the insulating material consists of several layers: 1 layer of soft or hard foam 1 layer of physiological protection. Instead of a cohesive sheet of soft or hard foam, the multilayer insulating material is available in such a way that the air-filled particles of the foam on a physiologically harmless, super flexible For reasons of cost savings, this is done by moving a film (e.g. aluminum or polyethylene) under an electrically charged grid. A magnetic field is created. The material to be shaken, namely air-filled particles, shoots out of a chute level Polystyrene or Polyuiebhan, through the magnetic field on the film, which is passed at a tight, measured speed, the surface of which is suitably prepared, e.g. by spraying on adhesive. This film, coated with polyurethane or polystyrene, is cut into formats that are precisely used in common foodstuffs and luxury foods ! v packs fit: for example, in an ice cream cup pack, the foam side is placed against the cardboard side of the cup, inside, and the ice cream cup, insulated in this way, is filled with ice cream as usual. The more or less thick foam layer insulates and the film layer, physiologically harmless, protects (insulates) the contents from undesired effects. The particular advantage of the "inner insulation" is that it is not damaged, neither during transport, nor by the consumer, who only removes part of the contents; Stay with the external insulation, which is quite possible. 4: It is inevitable that the insulation layers will be damaged if the consumer removes the contents, even partially. Protection claims: 1) Packaging for foodstuffs and luxury foods, characterized in that that in the well-known packaging of food and luxury items single or multi-layer * »insulation inserts can be inserted. 2) Isolation of food and luxury food packaging according to claim 1 characterized in that applied to foils, air-filled ", Foam beads on the packaging for food and beverages Beverages lying in, or directly on the food and luxury foods. 9210 * «* Kß ύ \)
