Definitions

  • insulating containers to be effective, must be obtained by molding in a single piece of a thick insulating material such as a foam of synthetic material.
  • This blank consists of a complex comprising an outer fiber face and the assembly gives a finished container which does not require any rigid outer envelope.
  • This container therefore includes only one piece.
  • the crease lines include a. chamfer at 45 [allowing the different faces thus determined on the blank to assemble without play.
  • the present invention deviates from known solutions and plans to use the insulating power of air in addition to the already known insulating elements such as a closed cell material.
  • the subject of the invention is an insulating packaging of the type comprising an inner envelope which must surround products and an outer box which must surround the envelope, characterized in that the inner envelope is constituted by a semi-rigid insulating complex. which must be folded in volume leaving a passage between the interior space it determines and the exterior while the box must contain with a small play the folded complex and must be closed as tightly as possible to confine a significant air volume prevailing, without movement, both inside and outside the envelope.
  • the parallelepiped box, the complex is provided with fold lines which determine six faces which must together constitute a substantially parallelepiped envelope intended to circumscribe the products and to be circumscribed by the box with a slight play .
  • the complex dui-face which must be placed against the bottom of the box has a slightly smaller perimeter than that of the opposite face so that the complex folded in slightly inverted truncated pyramidal volume can be easily introduced into the box preformed in parallelepiped volume.
  • an insulating package according to the invention comprises a semi-rigid complex 1 composed of a closed cell material 2 and of a reflective film 3 advantageously bi-directional.
  • the material 2 can, for example, consist of a foam of synthetic material such as expanded polystyrene and the reflective film can be obtained by metallization according to any process well known to those skilled in the art.
  • this complex is very effective on the one hand because of its innumerable closed cells each trapping a small quantity of air and, on the other hand.-because of the reflective film 3 which prevents the exchanges of temperature by radiation.
  • This complex must be placed in a box 4 preferably made of cardboard, in such a way that it circumscribes the complex folded in complete volume around the products to be packaged while leaving a clearance creating a substantial volume of air.
  • the box 4 is parallelepipedal so that the complex 1 is cut and marked with fold lines 5 which determine six faces 6 to 11 devoid of any assembly tab in order to be side by side with the adjacent face, after folding the complex 1 along lines 5.
  • the complex 1 has at least one edge which is particularly resistant to shocks and other mechanical forces which may result either from stacking (vertical crushing) or from lateral compressions.
  • the fold lines 5 are permanently marked and the complex 1 is folded so that the insulating foam 2 is located inside and the reflective film 3 outside because, as can be seen in FIG. 2 , the marking of the lines 5 is more accentuated on the side of the foam 2 than on the side of the film 3.
  • the box 4 preferably made of cardboard, is of any known type and preferably obtained from a cut and grooved blank then folded and kept erected automatically by means of a mechanical installation.
  • the complex 1 is folded to form a parallelepiped volume as outlined in FIG. 1, then is engaged in the box 4 according to the arrows F as can be seen in FIG. 3.
  • the face 7 of the complex 1 which must be placed against the bottom 4a of the box 4 to have a slightly smaller perimeter than that of the opposite face 9 , so that the folded complex 1 has a slightly inverted truncated pyramidal volume.
  • the faces 6 and 8 then have the shape of a slightly marked trapezium and in FIGS. 1 and 4 the difference in length has been deliberately exaggerated between the two long sides of each trapezoid to show the difference 6 on each of the short sides.
  • the complex 1 After removal of the mechanical positioning elements, the complex 1 is redeployed by natural elasticity, as can be seen in FIG. 4 where it can be seen that the faces 10 and 11 of the complex are slightly apart.
  • this position of the lateral faces of the complex 1 has the effect of immobilizing this complex 1 and its content by elastic support of these faces against the walls of the box 4.
  • the box 4 is made of cardboard and includes a cover which consists of an upper face and three side flaps 4b, 4c, 4d to be held on the body itself the box 4 by means of a tape of glue 14 which extends continuously on the three sides of the body of the box 4.
  • the box in line with the flaps 4b, 4c, 4d the box has a double thickness and no passage of air can occur between the body of the box and the folded flaps.
  • the box 4 When the packaged product is consumed, the box 4 is opened by peeling off the flaps 4b, 4c, 4d so that the box 4 is destroyed and cannot be used a second time.
  • the product is then removed after having raised the face 9 of the complex 1 or after having removed all of this complex 1 which is itself eliminated.
  • the container according to the invention is therefore of the "lost packaging" type, but its price is modest enough for the entire packaging to still represent an economy in comparison with the use of "volume” and very thick boxes, which must be stored in very large spaces which give rise to impractical handling.
  • the invention has been illustrated by an example according to which the box 4 is first set in volume and then receives the folded complex 1 but, in practice, it is also possible to provide for the simultaneous setting of the box 4 and of complex 1.
  • the main thing is to leave a significant volume of air in the box 4, to immobilize it and confine it to make the best use of its natural insulating power in addition to the "barrier" effects of the materials themselves.
