Corrugated cardboard box for the transport of fresh produce, which has improved insulation and leak-tightness properties and facilitates placing adhesive strips during the final sealing of the box

A corrugated cardboard box (1) for carrying fresh products, such as frozen fish, with improved insulation properties/leak tightness aimed to facilitate wrapping with adhesive strips during final sealing of the box, featured because it is made up of:

• a telescopic upper lid (2) and lower lid (4), that make up a second wall around an intermediate leak-tight container (3), each of them covering half the height of the container (3), the upper (2) and lower (4) lids come from one single template (17), the template (17) is made up of a base (12) from where two major walls (13), two minor walls (14) and four wings (15) are projected, the major walls (13) are made up of three foldable sections in a row, a distal section (18), a central section (19) and a proximal section (20), the minor walls (14) are made up of a distal section (21) with a central shoulder (16) located at the edge and a proximal section (22);
• and
• an intermediate leak-tight container (3) located inside the upper lid (2) and the lower lid (4), having bellow vertical folded edges (6) retained by a foldable panel (9) folded on top of them, the intermediate leak-tight container (3) coming from a template (5) other than the lids template (17), the template (5) of the intermediate leak-tight container (3) made up of a base (8) from where two major walls (23), two minor walls (24) and four foldable edges (6) are projected, the major walls (23) are made up of one section only and the minor walls (24) are made up of a proximal section (25) and a distal section which is the foldable panel (9).
