COMPREHENSIVE DESCRIPTION

[0045] The disclosure describes a corrugated cardboard box (1), basically made up of three pieces, just as described in FIG. 1one upper lid (2), one lower lid (4) and an intermediate leak-tight container (3). The upper lid (2) and the lower lid (4) are identical and come from the same template (17) design. The intermediate leak-tight container (3) come from a template (5) design, different from the upper lid (2) and from the lower lid (4).

[0046] The intermediate leak-tight container (3) is coated with a special cardboard, including polyethylene-coated paper preventing liquid content of the product (ice and blood) from leaking out through the walls of the box (1). Such inner leak-tight container (3) is located inside the upper lid (2) and the lower lid (4) and has bellow folded edges (6) retained by a foldable panel (9). Such container (3) can be assembled with folds only, and no cuts the liquid could leak out through.

[0047] The telescopic upper (2) and lower (4) lids make up a second wall around the intermediate leak-tight container (3), thus getting excellent thermal insulation.

[0048] The upper (2) and lower (4) lids, when assembled from outside the container (3), get together at half of the height of the container (3), thus facilitating the installation of a seal strip.

[0049] Just as described in FIG. 2, the template (5) of the intermediate leak-tight container (3) is made up of a base (8). From the base 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. The minor walls (24) are made up of a distal section (9) making up a collapsible panel and a proximal section (25). The template (5) has vertical/horizontal/oblique folding lines allowing assembly of such inner leak-tight container (3).

[0050] The edges (6) have a shoulder (7). The proximal section (25) of the minor walls (24) of the container (3) and the section that is the foldable panel (9) are attached to each other by folded portions (10) and among them there is a central groove (11).

[0051] When assembling the inner leak-tight container (3) based on the template (5), the edges (6) are bellow folded using the folding lines (27). The edges (6) may be located either inside/outside the body of the intermediate leak-tight container (3). In both cases the shoulders (7) are inserted into central (11) grooves, where the folded portions (10) located between the distal section (9) or collapsible panel and the proximal section (25) are set above the upper edge of the bellow folded edges (6), thus securing them into position. In case the folded edges (6) are located outside, the foldable panel (9) is also folded outwards from the container (3) covering such folded edges, just as described in FIGS. 1 and 6. Contrariwise, when folded edges (6) are inwards, the foldable panel (9) is also folded inwards, just as described in FIGS. 4C and 4D.

[0052] Just as described in FIG. 3, the templates (17) of the lids (2) and (4) are 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, 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) and a proximal section (22), where the distal section (21) has a central shoulder (16) at its edge.

[0053] When assembling the upper (2) and lower (4) lids, based on the template (17), the distal sections (18) of the major walls (13) are set along/parallel to the base of the lids (12). The shoulders (16) are located between such distal sections (18) of the major walls (13), (See FIG. 5F). In turn, the width of these distal sections (18) matches the width of the folded portions (10) of the container (3).

[0054] The distance between the two distal sections (18), set along/parallel to the base (12) of the lids (2) and (4), matches the width of the central groove (11) of the container (3) and the width of the shoulder (16) of the same minor walls (14) of the lids (2) and (4).

[0055] In order to form the lids (2) and (4) the template (17) must have vertical/horizontal folding lines allowing assembly of such lids.

[0056] The template (17) has cuts (26) between the wings (15) and the proximal section (20). This allows that when the major walls (13) are folded in their sections (18, 19, and 20) the wings (15) are set between the central sections (19) and the proximal sections (20). (See FIGS. 5D and 5E).
