  Next, the flap 28 is glued to the part of the cardboard board 1 located between the folding grooves 8 and 20 to produce, after folding of the assembly, the lower part of the box 2.

  FIGS. 3 to 6 show the conformation of a module 3 as a function of the grooving direction of the folding grooves in order to constitute the box 2 for the packaging of products, knowing that a box 2 may comprise at least two modules 3.

  It can be seen that the first folding consists in producing in part A of module 3 a side wall 40 and a cover 50 of box 2 by folding grooves 5, 6, 7 and 8.

  The cover 50 consists of two walls 51, 52 parallel and arranged one above the other. The walls 51, 52 are interconnected by side and opposite walls 40 and 41 separating said walls a certain distance from one another to form a free space 90.

  The inner wall 51 has deformable blanks 12, 13, 14 each provided with tabs 15 and 16. The lid 50 thus has an inner wall 51 in contact with the products to be packaged and an outer wall 52 protecting the first.

  The inner wall 51 is made by folding the grooves 5 and 6, while the outer wall 52 is obtained by folding the grooves 7 and 8.

  The inner wall 51 comprises at the level of the folding groove 6 and at the junction with the side wall 41 the pre-cut notches 17, 18.

  The outer wall 52 may be pierced with at least one not shown hole, allowing the passage of a finger facilitating the unfolding and shaping of the cover 50.

  The second folding consists in making part B of the module 3 the extension 45 of the side wall 40 and the bottom 60 of the box 2 by folding the grooves 23, 24, 25, 26 and 27.

  The bottom 60 consists of two walls 61, 62 parallel and arranged one above the other at a certain distance delimiting a free space 80. The walls 61, 62 are interconnected by side and opposite walls. 42 and 43 separating said walls a certain distance from one another. The wall 61 has the circular cutouts 29, 30, 31 each intended to receive a product to be packaged. The bottom 60 thus has an inner wall 61 in contact with the products to be packaged and an outer wall 62 protecting the first.

  The inner wall 61 is made by folding the grooves 23, 24 and 25, while the outer wall 62 is obtained by folding the grooves 27.

  The bottom 60 has a side wall 44 obtained by folding the grooves 25 and 26 to extend the wall 43 and face and in a plane parallel to that of the wall 40 of the cover 50. The side wall 44 extends above the wall 61 and comprises at the level of the folding groove 26 the pre-cut portions forming the hooking tabs 32, 33. The latter are provided to cooperate with the notches 17, 18 provided in the cover 50 in order to close and open the box 2. The side wall 44 is glued, after folding the grooves 25, 26, on the inner face of the wall 43 of the bottom 60. and 8, there has been shown blocking means of the bottom 60 in the unfolded position so that the latter resists the weight of the products to be packaged.

  For this, the outer wall 62 of the bottom 60 has pre-cut portions forming locking tongues 34, 35 which are folded inside said bottom towards the inner wall 61 so that said locking tongues 34, 35 are immediate proximity of said inner wall 61.

  The locking tabs 34, 35 form shims between the inner and outer walls 62 and 62 to maintain and lock the parallelogram-shaped profile of the bottom 60 when in the unfolded position.

  FIG. 9 shows a variant of the bottom blocking means 60 so that the latter can withstand the weight of the products to be packaged without risking the collapse of the box 2. For this purpose, the outer wall 62 of the bottom 60 is extended at each end by reinforcement strips 63, coming after folding of the latter to enter the free space 80 and between the outer wall 62 and the inner wall 61 in order to make a support wedge and blocking at each end of the bottom 60. Also, the reinforcing strips 63 close the ends of the bottom 60 to protect the free space 80 provided between the inner walls 61 and outer 62. 45 is shown in Figure 10, a box 2 in which is conditioned a product, such as, for example, eggs 70 knowing that it can be packed any other product without changing the subject of the invention.

  It is found that one end of the egg 70 is placed inside one of the circular cutouts 29, 30, 31 formed in the inner wall 61 of the bottom 60.

  The egg 70 is introduced inside the corresponding circular cutout 29, 30, 31 so that its outer diameter comes into contact with the inner periphery of said circular cutout.

  When the egg 70 is positioned in the corresponding circular cutout 29, 30, 31, it is noted that the end of said egg is included in the free space 80 provided between the inner walls 61 and outer 62 of the bottom 60 without ever coming into contact with said outer wall 62.

  The other end of the egg 70 is placed during the closure of the lid 50 inside the corresponding deformable cutout 12, 13, 14 so that each tab 15 and 16, after deformation, perfectly matches the contour of the Egg 70 or any other product to fit the profile of the end of the latter.

  The deformation of the tongues 15, 16 makes it possible to ensure that the egg 70 remains play-free between the inner wall 51 of the lid 50 and the inner wall 61 of the bottom 60 of the box 2.

  When the egg 70 is positioned in the deformable cutout 12, 13, 14 corresponding, it is noted that the end of said egg is included in the free space 90 provided between the inner walls 51 and outer 52 of the lid 50 without ever coming into contact with said outer wall 52.

  It is found that the module 3 constituting the box 2 has the particularity of having a lid 50 and a bottom 60 double wall to protect the packaged products from any external shock. Also, the closure of the cover 50 via the notches 17, 18 and the hooking tabs 32, 33 may be reinforced by a self-adhesive strip, not shown, detachable and repositionable.

  The tabs 32, 33 allow the opening and closing of the module 3 by the user or the consumer.

  In FIGS. 11 and 12, there is shown a box 2 comprising two modules 3 as described above which are provided on the same cardboard board 1 and connected to each other at the axis YY 'of the latter by means of the Folding groove Rp.

  After the conformation of the two modules 3, the latter are folded according to the arrows F against each other by folding the groove Rp so that the vertical walls 40 of each module are in contact with each other. other. The two modules 3 are immobilized one against the other by means of the hooking tab 19 which cooperates with the notch 22 provided respectively on each wall 40 of each module.

  It goes without saying that the box 2 object of the present invention can allow the packaging of any other food or non-food product.

  Also, each visible outer face of each module 3 can receive an advertising impression or the like. It must also be understood that the foregoing description has been given by way of example only and that it in no way limits the scope of the invention which could not be overcome by replacing the execution details described. by any other equivalent. 15
