Definitions

  • temperatures are very different depending on the nature and composition of the products. They are, for example, + 8 ° C for butter and cheese, + 13 ° C for meat and fish, approximately + 42 ° C for pre-cooked or pre-cooked foods to be eaten hot (roast chickens, hot hams, etc.), from -8 ° C for frozen food products, the latter temperature being the one above which these products cannot be refrozen without danger to the health of consumers, of around + 18 ° C for certain pharmaceutical products (suppositories for example), around + 20 ° C for flowers and seed pieces, etc.
  • the subject of the present invention is a material making it possible to produce isothermal and hermetic packaging capable of maintaining these products at temperatures which are satisfactory from this point of view during a relatively long time interval. In other words, their temperature only tends very slowly towards their critical temperature, which makes it possible to keep these products for several hours (from 2 to 12 hours depending on the case), at temperatures for which they are suitable for consumption. or their use, these durations largely covering transport times.
  • the material according to the present invention consists of a flexible sheet having a side with high reflecting power and comprising a layer of material with low thermal conduction power, for example plastic foam or non-woven textile fibers. Such a material is described in French patent No. 2345295 to REVERCHON-ROCAPHANE.
  • the packaging is obtained by wrapping the sheet one or more times around the product to be stored, the reflecting face being placed outside, then closed by independent means or provided for this purpose, by tightening together the juxtaposed parts of the longitudinal edges and applying the free transverse edge against the body of the package.
  • These closing means may advantageously be constituted by self-adhesive surfaces.
  • the packaging thus produced has, in addition to the qualities noted above, the fact of providing good protection against shocks.
  • the material according to the invention has the advantage, over isothermal packaging materials of the above-mentioned type provided with self-adhesive closing means, of having a very simple structure, of being easy to manufacture and of a relatively low cost price, and yet very reliable.
  • This packaging in which the closure means consist of self-adhesive surfaces, which has one of the faces of the flexible sheet, intended to be applied by pressure against the corresponding surfaces of the other side of this sheet, when the packaging is finished, is characterized by the fact that said sheet has an adhesive face partially covered by the layer with low thermal conduction power so that the uncoated surfaces form said adhesive surfaces.
  • the isothermal packaging material shown in the drawing consists of a flexible rectangular sheet 10, made of polyvinyl, 40 cm wide, 90 cm long and 0.5 mm thick, white and shiny on its outer face and self-adhesive on its inner face, and with a layer of plastic foam 11, with open cells, 5 mm thick, self-adhesive on the inner face of the sheet.
  • This layer 11 is discontinuous so as to reveal the adhesive face of the sheet 10 along a transverse area 12 and along two longitudinal strips 13.
  • Figures 2 and 3 show how the sheet illustrated in Figure 1 was used to package a 400g ice cream block.
  • the sheet was wrapped three times around the pad and the packaging thus obtained was closed by pressing the adhesive pad 12 and the adhesive strips 13 against the corresponding surfaces of the glossy face of the sheet 10.
  • This package placed in an ambient environment at a temperature of + 22 ° C, keeps the ice cream block, initially at a temperature of -20 ° C for about 2 hours before it reaches the temperature of - 8 ° C from which the cream begins to melt (Figure 4).
  • This performance is very much superior to that of the tote bags or aluminum bags found in supermarkets, packaging that only keeps the same pavement under the same conditions for barely an hour.
  • Sheets such as that shown in FIG. 1, will advantageously be produced in series and continuously, stored in rolls and cut up as and when required by cutting the sheets one after the other.
  • the packaging sheet shown in the drawing is more specifically intended for prepackaged products.
  • an additional inner layer may be provided. keep quiet, partially covering the foam layer, for example aluminum foil, PVC film, greasy paper, to protect the product and prevent it from entering the foam.
  • This additional layer can be glued to the foam layer only along one edge so as not to be wrinkled.
  • the flexible sheet may include a non-glued area contiguous to the area 12 facilitating the gripping of the edge for opening the packaging.
  • sealing and thermal insulation of the edges of the packaging are reinforced by the continuous bonding zone formed by the pad 12 and the strips 13 and by the pressure which the foam undergoes at this zone.
