The interchangeable flexible pack has a parallelepiped-shape that will fit in the box and includes a plurality of structures for engaging with the structure for supporting and the structure for blocking. ## Claims ### Claim 1 A rigid container comprising: an interchangeable flexible pack; and a substantially parallelepiped-shaped box comprising: an upper edge comprising a plurality of means for supporting the interchangeable flexible pack and a plurality of means for blocking the interchangeable flexible pack and a closable lid wherein the interchangeable flexible pack has a parallelepiped-shape that will fit in the box and comprises a plurality of means for engaging with the means for supporting and the means for blocking. ### Claim 2 (depends on 1) A rigid container according to claim 1 wherein the means for supporting the interchangeable flexible pack comprise at least one pair of opposed tabs protruding inside the box that are suitable for supporting a perimetral frame located on an upper face of the interchangeable flexible pack. ### Claim 3 (depends on 1) A rigid container according to claim 1 wherein the means for blocking the interchangeable flexible pack comprise blocking tabs protruding inside the box and positioned at a higher level than the means for supporting the interchangeable flexible pack so that the blocking tabs can be passed over by a frame of the interchangeable flexible pack which comprises the means for engaging when the interchangeable flexible pack is inserted into the box. ### Claim 4 (depends on 1) A rigid container according to claim 1, wherein the closable lid is hinged to the upper edge of the box and has an inner perimetral channel suitable for receiving the upper edge of the box when the lid is in a closed position. ### Claim 5 (depends on 4) A rigid container according to claim 4 wherein a sealing gasket is positioned on a bottom of the inner perimetral channel. ### Claim 6 (depends on 1) A rigid container according to claim 1 wherein the interchangeable flexible pack comprises a flexible film comprising a first fold on a first parallelepiped side a second fold, substantially perpendicular to the first fold, on a second parallelepiped side and a third fold, substantially perpendicular to the first fold, on a third parallelepiped side, the second parallelepiped side and the third parallelepiped side being adjacent first parallelepiped side. ### Claim 7 (depends on 1) A rigid container according to claim 1 wherein the interchangeable flexible pack is a vacuum pack and contains a product in powder form. ### Claim 8 (depends on 1) A rigid container according to claim 1 wherein the box is made of at least one material selected from the group consisting of cardboard, plastic the metal. ### Claim 9 (depends on 2) A rigid container according to claim 2 wherein the means for blocking the interchangeable flexible pack comprise blocking tabs protruding insider the box and positioned at a higher level than the at least one pair of opposed tabs so that the blocking tabs can be passed over by a frame of the interchangeable flexible pack which comprises the means for engaging when the interchangeable flexible pack is inserted into the box. ### Claim 10 (depends on 2) A rigid container according to claim 2 wherein the closable lid is hinged to the upper edge of the box and has an inner perimetral channel suitable for receiving the upper edge of the box when the lid is in a closed position. ### Claim 11 (depends on 3) A rigid container according to claim 3 wherein the closable lid is hinged to the upper edge of the box and has an inner perimetral channel suitable for receiving the upper edge of the box when the lid is in a closed position. ### Claim 12 (depends on 2) A rigid container according to claim 2 further comprising a peel-off diaphragm is foreseen with a grasping flap, the peel-off diaphragm being attached to an upper surface of the perimetral frame. ### Claim 13 (depends on 9) A rigid container according to claim 9 further comprising a peel-off diaphragm is foreseen with a grasping flap, the peel-off diaphragm being attached to an upper surface of the perimetral frame. ### Claim 14 (depends on 10) A rigid container according to claim 10 further comprising a peel-off diaphragm is foreseen with a grasping a flap, the peel-off diaphragm being attached to an upper surface of the perimetral frame. ### Claim 15 (depends on 2) A rigid container according to claim 2 wherein the interchangeable flexible pack comprises a flexible film comprising a first fold on a first parallelepiped side a second fold, substantially perpendicular to the first fold, on a second parallelepiped side and a third fold, substantially perpendicular to the first fold, on a third parallelepiped side, the second parallelepiped side and the first parallelepiped side being adjacent the first parallelepiped side. ### Claim 16 (depends on 15) A rigid container according to claim 15 further comprising a peel-off diaphragm is foreseen with a grasping flap, the peel-off diaphragm being attached to an upper surface of the perimetral frame. ### Claim 17 (depends on 3) A rigid container according to claim 3 wherein the interchangeable flexible pack comprises a flexible film comprising a first fold on a first parallelepiped side a second fold, substantially perpendicular to the first fold, on a second parallelepiped side and a third fold, substantially perpendicular to the first fold, on a third parallelepiped side, the second parallelepiped side and the third parallelepiped side being adjacent the first parallelepiped side. ### Claim 18 (depends on 4) A rigid container according to claim 4 wherein the interchangeable flexible pack comprises a flexible film comprising a first fold on a first parallelepiped side a second fold, substantially perpendicular to the first fold, on a second parallelepiped side and a third fold, substantially perpendicular to the first fold, on a third parallelepiped side, the second parallelepiped side and the third parallelepiped side being adjacent the first parallelepiped side. ### Claim 19 (depends on 5) A rigid container according to claim 5 wherein the interchangeable flexible pack comprises a flexible film comprising a first fold on a first parallelepiped side a second fold, substantially perpendicular to the first fold, on a second parallelepiped side and a third fold, substantially perpendicular to the first fold, on a third parallelepiped side, the second parallelepiped side and the third parallelepiped side being adjacent the first parallelepiped side.
