Storage box

A reusable storage box, said box comprising:

• a storage box formed from a single sheet of a corrugated cardboard provided with a plurality of reinforcing channels extending through said single sheet in one direction;
• a rear face, a front face, an upper face, a lower face and two side faces;
• said rear face comprises a first sector provided with an oblique folding line defining a first joining zone, a second sector provided with an oblique folding line joined to said first sector at said first joining zone, a third sector formed with an oblique folding line defining a second joining zone, and a fourth sector joined to said third sector at said second joining zone;
• a first lid sector and a second lid sector hingedly connected to one of the upper face and the lower face along first and second folding lines;
• each said lid sector is formed with a complimentary flap, a flap of the first lid sector is formed with a central region disposed between two side regions, the central region of the first sector extends inwardly from a level of said side regions to form a recess, a flap of the second lid sector is formed with a central region disposed between two side regions, the central region of the second sector extends outwardly from a level of the side regions to form a projection;
• the flap of the first lid sector formed with a pair of spaced from each other engaging grooves, said engaging grooves extending inwardly from the recess;
• the flap of the second lid sector formed with a pair of spaced from each other engaging grooves extending inwardly from the side regions;
• so that in a closed condition of the reusable storage box said projection of the second lid sector is received within said recess of the first lid sector, and the engaging grooves of the first lid sector engage the engaging grooves of the second lid sector;
• and
• a reinforced area developed at a central part of the lid in said closed condition of the box by the flaps of the first and second lid sectors overlapping each other, so as to form a double layer zone by said single sheet of the corrugated cardboard at said central part of the lid, said reinforced area being further fortified by the plurality of the reinforcing channels provided in said first and second lid sectors oriented substantially perpendicular to the first and second folding lines.
