  • a container according to the invention comprises a plastic sheet 1 which constitutes, in one piece, an upper area 2, a housing 3 and side walls 4 determining the height container and forming a continuous tight seal, like a bottomless box.
  • the plastic film is lined with a layer of cardboard 5, here in one piece, with one hand, in the upper area 2 a panel 5 has passed through a central opening 5 b which constitutes a passage towards the volume determined by the side walls 4, and on the other hand as many panels 5 c as there are walls 4.
  • the plastic sheet 1 extends through the passage 5 b and the housing 3 has a height h substantially equal to that H of the side walls 4-5, but slightly less in order to leave a clearance x between the bottom 6 of the housing 5 and a plane p on which the container can be placed.
  • a cover 7 is applied to the frame 2-5 and is fixed to it by any known means: gluing, hot welding or ultrasonic welding. etc.
  • the cardboard part 5 is printed on its outer face laminated to the sheet 1, which is transparent to allow the printing of the cardboard to appear.
  • the cardboard panels 5 c are simply adjacent because there are no covering tabs, unlike a method well known to date.
  • the container is waterproof thanks to the plastic sheet 1 which is continuous and which externally covers the discontinuities of the corners of the cardboard part.
  • the container is therefore resistant to external aggressions and arrives in perfect condition for presentation at points of sale, despite transport, intermediate storage and handling.
  • the cardboard contributes to the robustness, rigidity and resistance of the container, but it is placed under the waterproof layer and its decor is therefore protected.
  • the cardboard part 5 is advantageously formed in one piece, by cutting and creasing a single cardboard blank. Peripheral creasing lines allow the walls 5 c to be folded down by folding. This blank can easily receive any impression in all colors thanks to the well-known hydrophilicity of the cardboard, which is also robust and has the desired rigidity to give the container good resistance to crushing, impact and other constraints inherent in handling. containers. This embodiment also leads as to leave gaps at the corners of the container, the fact that the panels 5 c neighbors are just adjacent, without covering element.
  • the fixing of the sheet 1, basically necessary for the "fixing" of the housing 3 on the cardboard part 5, has the consequence of creating on the outside of the container a continuous film coating (even in line with the discontinuities of the cardboard part 5 ) whose appearance is particularly aesthetic and attractive.
  • the presence of synthetic material on the outer face of the frame 1 makes it possible to apply the cover 7 by hot welding, the latter comprising for this purpose a sheet of heat-sealable synthetic material 8.
  • a sheet of box 9 to receive prints either for useful information, or for advertising or decoration.
  • FIG. 2 we see a container similar to that of FIG. 1 but comprising a variant according to which the sheet 1 is cut to be a little longer and a little wider than what would be strictly necessary for its alignment with the bottom of the cardboard panels 5 c .
  • the sheet 4 is straightened along all of its edges to form a continuous peripheral rim 10 at the bottom of the side walls 4-5.
  • the second cover may also be composed of a heat-sealable sheet 13 and a sheet of cardboard 14, the latter having in this case other reasons for being than that of the cover 7: it gives rigidity of the entire container since it keeps the walls 4-5 and prevents them from bending towards the center of the container and it contributes to thermal insulation by separating the air occluded in volume 12 from that of the atmosphere outside. By the rigidity that it brings, the second cover 11 is therefore useful even if the insulation qualities of the container are not important for this or that product.
  • FIG. 4 shows an alternative embodiment of the invention according to which lines of weakness are provided, for example alignments of perforations 20, placed at places judiciously chosen to allow the container to be fragmented.
  • This can be useful for separating the plastic housing 3 from the cardboard part or for dividing a container provided with several independent housings. It is indeed possible to provide a container having an upper area having a multiple frame, in the manner of a grating, and a sheet of synthetic material forming as many housings as there are "boxes" between the cardboard strips. . It is therefore interesting to be able to split the container, each housing of which represents a portion. If the products packed in such a container must be kept cold, the container is placed in a refrigerator and the portions are taken one by one by cutting the frame and sealing it along the perforations 20.
  • the container As we know, it is advantageous to be able to stack several identical containers while preventing them from getting caught one in the other. To this end, it is expected that the perimeter of the container at the level of the cover 7 is smaller than the perimeter at the bottom of the side walls 4-5. As seen in the drawing, the container then has a vertical section in the shape of a trapezoid. This geometry alone allows an upper container to cover the top of a lower container as seen in Figure 5. But it is not satisfactory with containers according to the invention because these would rest on the lids lower containers by the housing 3 which could be too flexible or too fragile to constitute a serious base. This is why, according to the invention, feet 30 are also provided at at least some of the corners of each container, so that they contact a lower container before the housing 5 reaches the latter.
  • the feet 30 are dimensioned so that their lower part or base 31 is a little below the lower edges of the walls 4-5.
  • the upper container can slightly cover the lower container to ensure lateral stability and the housing 3 is located a little above the lower container, that is to say protected against knocks, pressures and friction.
  • the feet 30 can be made up as will now be described with reference to FIGS. 5, 6 and 7.
  • the cardboard walls 5 c are not only integral with the upper area 2, but also with legs which connect them two by two at each corner of the container (here four since the container is quadrangular). Creasing lines 32, 33 and 34 determine two flaps 35 and 36 and its located so that when the walls 5 c are folded relative to the upper area 2, the flaps 35 and 36 fold one against the other. other towards the inside of the container and not towards the outside, as can be seen in Figure 6.
  • the flaps 35 and 36 are limited by edges 37 and 38 perpendicular to the lines 32 and 34 and spaced from the edges of the walls 2 by a distance y equal to the depth of the nesting which it is desired to obtain during the stacking of two containers ( Figure 5).
  • the flaps 35 and 36 are also cut by two converging lines which form a sort of notch 39 and, after folding the flaps 35 and 36 against each other, these two lines become adjacent and together constitute the base 31 of the feet. 30.
  • the flaps 35 and 36 fold one against the other symmetrically so that a natural equilibrium is found when the flaps extend substantially along the bisector of the angle made by the two panels 5 c .
  • the container is quadrangular, the walls are perpendicular and therefore the feet 30 are approximately an angle of forty five degrees with the adjacent panels 5 c.
  • the flaps 35 and 36 are interconnected and as such they connect two neighboring panels, they do not create any sealing of the cardboard part (moreover hydrophilic in itself) and here again leave a discontinuity of the cardboard part of the walls. This is particularly well seen in FIG 6. Therefore, still qualifies "adjacent" two neighboring panels 5 c, due to the discontinuity of the walls. Even supposing that the flaps 35 and 36 are glued to each other by means of a waterproof adhesive, this sealing would be insignificant since it would lead to a complication of manufacturing, an increase in the cost of production and would not have practically no effect on the aesthetic appearance of the finished container.
  • FIG. 6 shows particularly well how the continuous sheet 1 ensures both the external tightness of the walls of the container and reinforces the angles by covering the discontinuities of the cardboard part 5. Note that this quality is independent of the position of the flaps 35-36 inside the walls 5 c and the presence or absence of a second plastic sheet on the internal face of the cardboard part 5 (see FIG. 13 and corresponding description).
  • FIG. 7 By observing FIG. 7, it can be seen that in order to provide the passage 5 b of the cardboard part 5, a central zone 40 is created. In FIGS. 1 to 6, it has been assumed that this central zone 40 is eliminated.
  • FIG. 8 illustrates a possibility of using this zone 40.
  • the zone 40 When cutting the cardboard blank, the zone 40 is held in its place, for example by providing uncut bridges between it and its surroundings, as is known in oneself. Subsequently, the zone 40 is detached and placed directly above the place where the housing 3 must be located. When the sheet 1 is put in place, the bottom 6 of the housing 3 meets the zone 40 against which it sticks. After fixing the cardboard part 5 and the plastic sheet 1, the area 40 is therefore secured under the bottom 6 of the housing 3, as can be seen in FIG. 8. This strengthens the resistance of the housing 3 which is able to withstand shocks, pressures or friction when handling the container.
  • the central area 40 is the entire surface board located inside the frame 5 and has, therefore, the housing 3 is exclusively made of synthetic material, except for its bottom 6 when zone 40 is added to it.
  • FIGS. 9-10 Another solution can also be adopted which consists in using the central cardboard area 40 to reinforce the plastic sheet 1.
  • This reinforcement can take two forms which are illustrated respectively by FIGS. 9-10 on the one hand and 11-12 on the other hand.
  • the central zone 40 is separated from the inner sides of the frame 5 a by crease lines 41 and its surface is cut along lines 42 coming from the angles of the frame 5 a and determining four legs 43, 44, 45 and 46.
  • the legs 44 and 46 are triangular while the legs 43 and 45 are trapezoidal.
  • the tabs 43 and 46 are folded down at angles determined by the shape which one wishes to give to the housing 3. If the walls of the latter are inclined so that the housing 3 has the shape of an inverted pyramid trunk, for example, the legs 43 and 46 will be folded at angles at the base of these walls.
  • the housing 3 is parallelepipedic so that the legs 43 to 46 are in planes perpendicular to that of the frame 5 a .
  • the sheet 1 When the sheet 1 is put in place by thermoforming, it molds against the legs 43 and 46, covers them whole and sticks to them as shown in FIG. 10.
  • the finished container thus has great robustness because the walls of the housing 3 are stiffened and reinforced by the cardboard tabs 43 to 46.
  • this construction eliminates the sharp edges of the passage 5 b that can be seen in FIGS. 1 to 5 since this passage is obtained by cutting out the frame 5 a and the zone 40.
  • K height of tabs 43 and 46 has the maximum possible value that is equal to half the distance separating the two opposite sides of the frame 5 to the nearest or, what amounts to the same, the two closest opposed sides of the passage created during the folding of the legs 43-46 for the sheet 1.
  • the legs 44 and 46 have the same height K since the lines 42 are the bisector of a right angle.
  • the central zone is cut out by four lines closed on themselves 50 to determine a central zone 51 and by four oblique lines 52 coming from the internal angles of the frame 5 a .
  • the central zone 51 has a smaller surface than that 40 of the solution of FIGS. 7-8 but here there are in addition four legs 53, 54, 55 and 56.
  • This solution is a compromise between the structures of FIGS. 7-8 d 'on the one hand and 9-10 on the other.
  • there is a central part 51 which can be placed under the bottom 6 of the housing 3, as shown in FIG. 12 while benefiting from the presence of the legs 53-56 which remove the sharp edges of the part 5 has, as explained above.
  • FIG. 13 one sees an embodiment of the invention according to which a second sheet of synthetic material 60 is placed on the inner face of the cardboard panels 5 b , under the frame 5 a , against the housing. 3 and under its bottom 6.
  • the entire cardboard part 5 of the container is then entirely wrapped in synthetic material that is waterproof. It is good to associate this solution with that which provides for the creation of a rim 10 so that a corresponding rim 61 of the sheet 60 can be welded to it.
  • the lower edge of the cardboard panels 5 b is then also enclosed.
  • a container of this type is particularly efficient since it benefits from all the advantages of cardboard: solidity, rigidity, printability and all the advantages of synthetic materials: sealing, rot-proof, neutrality, shine.
  • Such a container can be applied to obtain "boiling bags", a term which designates containers capable of withstanding the action of boiling water in which they are immersed to heat their contents.
  • the blank of FIG. 14 always includes a frame 5 a and walls 5 b joined by legs which should constitute feet 30.
  • the frame 5 a has a branch 100 parallel to the short sides and connecting the long sides as well as a branch 101 perpendicular to the branch 100 and joining the latter to a small side.
  • the sheet of synthetic material 1 forms as many housings as there are passages, that is to say three in this case: 500, 501 and 502 (the housing 502 is not visible because it is outside the plane of the section in FIG. 15).
  • the three dwellings must receive products, either to prevent them from mixing, or to better protect them.
  • a single lid 7 closes this container by being fixed not only to the frame 1 but also to the branches 100 and 101 to isolate the various housings.
  • the cover 7 is intended to be removed entirely to release the three compartments at the same time.

  • the upper area 5 a has a peripheral frame and branches 102 connecting the long inner sides of said frame and branches 103 connecting the short sides, which determines quadrangular passages 303, equal to one another and regularly distributed.
  • the container has fifteen passages 303, to receive a sheet of synthetic material having as many equal tight housings 503.
  • the assembly is closed by a single lid 701, attached not only on the actual frame of the upper area 5a but also on the legs 102 and 103.
  • Out of 702 lines to the right of the branches 102 and 103 make it possible to tear off the seal 701 fraction by fraction, above each housing 503.
  • the synthetic material can be, as is known per se, a simple or complex sheet, thermoformable or stampable.
  • the cardboard and the synthetic material can be bonded using a cold or hot adhesive or alternatively by locking hollows and reliefs of any known type.
  • the container can be quadrangular as is the most frequent case, but also circular or polygonal.

  • a single cover can be provided for several housings (split or not) or, on the contrary, one can be provided with a cover for each housing.
  • a cardboard blank is first created which is printed, grooved and cut to present a central incised area of at least one passage.
  • “Incised” means that the central area can as well be hollowed out (FIGS. 1 to 8 and 11 to 17) from one or more openings from which the cardboard has been removed, as to be simply notched without removal of material, which is in particular the case of FIGS. 9 and 10.

Each blank is placed in a bell on this relief, so that the cardboard panels 5 c of the walls are immobilized in their position of use, the upper area 5 a being placed on the relief. The adjacent edges of the panels 5 c join more or less intimately depending on whether or not they are provided with junction flaps 35-36.
