Description

Title of the invention

) Field of application of the invention

The invention relates to a Frischhaltetasehe, in particular for the transport of hot or cold food to be kept, such as, Tiefkuehlkost *

Characteristic of the known technical solutions Insulating bags made of paper for v / poor or refrigerated foods are known in which cotton wool of natural or artificial fibers is arranged between two paper layers. However, such insulating bags are not very durable and also expensive to manufacture. There is also already known a polyethylene foam film, in the manufacture of which a blowing agent is added to the polyethylene granules, which gives the resultant film a gas content of about 50 percent of its volume. Although such films are relatively durable and can also be easily processed into simple bags, their insulating effect is sufficient for storing eg frozen foods, in particular during transport, in most cases not * In order to remedy this IT disadvantage, transport packaging continued to be used proposed, which consists of a sealable bag or bag made of plastic films with Fuell- or Entnahmeoeffnung and in which the bag or the bag of an at least two-ply foil made of plastic foam

is produced, wherein between the individual layers for heat insulation a thin layer of air "is (DE-OS 28 53 ö61)" As an essential feature is next to various closure options (adhesive strips, pressure sensitive adhesive tape, Velcro straps, interlocking holes and pushbuttons) found that between spacers are arranged from a heisa-stamped polyvinyl ethylene foil to the two film layers *

First of all, box is disadvantageous to all pouches listed ₉ that they are manufactured in more or less fashionable colors, its reflection effect is different depending on the color present * This is especially true when the bag or the bag when transporting frozen foods is exposed to direct solar radiation, because the different colors naturally have a different heat absorption characteristic "Darueberhiiiaus the production of the latter bag is still relatively expensive and expensive, especially because of the required spacers to create the required air cushion © Furthermore, the proposed materials are not very hard-wearing, this is especially true when the bag or the bag is folded one or more times for reasons of space-saving transport (in the empty state) · If the folding process is repeated several times, the proposed mat erialia have negative effects after a relatively short time (eg "fractures in the material), which significantly reduce the performance characteristics"

Object of the invention

It is an object of the invention to develop a freshness-keeping bag, in particular for the transport of foodstuffs to be kept warm and cold, such as frozen food, the use of which avoids the disadvantages described above and which even after prolonged use does not indicate any reduction in the use properties.

Explanation of the essence of the invention

The object of the invention is to develop a freshness-keeping bag, in particular for transporting foodstuffs to be kept warm or cold, such as frozen foods, which, in addition to a high degree of reflectivity, have a high heat insulation even under direct irradiation, and which are also protected by continuous, multiple folding (eg, in the case of space-saving transport in the empty state) is not adversely affected in its service properties ·

Gemaesa the invention, this object is achieved by means of a preferably closable by means of zipper fresh keep bag, which is made of a material consisting of a multilayer film composite of ΡΞΤΡ / AL and on its AL inside for heat insulation, a fabric and / or foam mat , for example, is laminated from PUR foam, wherein the bag, which is composed of two side panels and a three-part circulation base, in a conventional manner at the sides and bottom with binding tape is sewed together, so / ie with two Handles secured to the side panels by a hook »To protect the bag material against contamination, an adjustment bag made of PVC film is loosely inserted into the bag ·

Ausfuehrungsbeispiel

The invention will be explained in more detail below using an exemplary embodiment.

Fig. 1 is a perspective view of the freshness-keeping bag according to the invention;

FIG. 2 shows a section A-A according to FIG. 1.

The Prischhaltetasche according to the invention is composed of two Seitonteilen 5 and an out of two side panels 6 and a bottom part 7 existing Uralaufboden, being used as Tascheniaaterial a multilayer film composite of PETP / AL · According to the invention is on the AL inside of the film composite for heat insulation a polyurethane foam laminated on *

The bag is preferably closed with a zip fastener 1, whereby all associated bag parts are stitched together in a manner known per se with a suitable binding tape 2. Henkel are furthermore arranged on the side parts and, in order to protect the bag material against theft, a setting bag is inserted into the freshness-keeping bag 4 made of PVC polish loosely
