Foldable package with simplified shaping

1. A package comprising a case defining a stowing volume, and a cover intended to close the stowing volume of the case, the case having a bottom and a peripheral rim comprising:

a first panel;

a second panel;

a third panel opposite the first panel;

a fourth panel opposite the second panel,

the first panel, the second panel, the third panel and the fourth panel can adopt:

a stowed position in which each of the panels extends substantially parallel to the bottom;

a use position in which each of the panels extends substantially perpendicular to the bottom;

wherein the case comprises a rigid element connected to the first panel and to the third panel by an elastic connection, the rigid element being movable between:

a storage position of the case corresponding to the stowed position of the panels of the peripheral rim, in which the rigid element is located near the bottom;

a use position of the case corresponding to the use position of the panels of the peripheral rim, in which the rigid element is spaced from the bottom,

the elastic connection tending to displace the rigid element from its storage position to its use position.

2. The package according to claim 1 , wherein the case also comprises at least:

a first drive element interposed between the first panel and the second panel or the fourth panel of the peripheral rim;

a second drive element interposed between the third panel and the second panel or the fourth panel of the peripheral rim.

3. The package according to claim 1 , wherein the rigid element is a plate of a length equal to the distance between the first panel and the third panel in their use position.

4. The package according to claim 3 , wherein the plate carries a non-slip coating and/or a flexible material allowing the retention of an object in the stowing volume of the case.

5. The package according to claim 1 , wherein the elastic connection comprises at least one elastically deformable band or cable.

6. The package according to claim 1 , wherein the case also comprises means for retaining the first panel, the second panel, the third panel and the fourth panel in their use position.

7. The package according to claim 6 , wherein the retaining means comprise two parts each permanently mounted on the peripheral rim of the case.

8. The package according to claim 1 , wherein the cover comprises:

a first flap pivotally mounted on the first panel of the peripheral rim;

a second flap pivotally mounted on the third panel of the peripheral rim;

a third flap pivotally mounted on the second panel of the peripheral rim;

a fourth flap pivotally mounted on the fourth panel of the peripheral rim, each flap being movable between a closed position in which it prevents access to the stowing volume of the case, and an open position in which it leaves free access to the stowing volume of the case.

9. The package according to claim 8 , wherein, in their closed position, the first flap and the second flap extend in the continuation of one another, and, the third flap and the fourth flap extend overlapping one another and overlapping the first flap and the second flap.

10. The package according to claim 8 , wherein, in their closed position, the third flap and the fourth flap extend in the continuation of one another, and, the first flap and the second flap extend overlapping one another and overlapping the third flap and the fourth flap.

11. The package according to claim 8 , wherein the first flap and the second flap, or the third flap and the fourth flap, which are in line, each have an internal surface facing the stowing volume in their closed position, the internal surface being covered with a non-slip coating and/or a flexible material capable of being deformed by an object contained in the stowing volume.

12. The package according to claim 1 , wherein the package comprises a digital communication panel secured to one of the first panel, the second panel, the third panel or the fourth panel of the peripheral edge of the case, or to the cover.
