Claim 12:
13. A recyclable, thermally insulated shipping container comprising:
a cardboard outer box having a bottom wall, a plurality of sidewalls and a top wall;
a cardboard inner liner assembly comprising a cardboard inner box having a bottom wall and a plurality of sidewalls defining a product cavity,
said inner liner assembly further comprising a cardboard liner flange having a continuous top shelf portion, a plurality of outer securing tabs projecting downwardly from an outer peripheral edge of the top shelf portion, and a plurality of inner securing tabs projecting downwardly from an inner peripheral edge of the top shelf portion,
said inner securing tabs being received within the sidewalls of the inner box and secured to inner surfaces of said inner box sidewalls,
said outer securing tabs being received within the sidewalls of the outer box and secured to inner surfaces of said outer box sidewalls,
said inner liner assembly being secured within said outer box such that the shelf portion is positioned below the top wall thereof to create a lid cavity above said shelf portion and below said top wall,
said inner liner assembly and said outer box cooperating to form a side thermal insulating cavity between said respective sidewalls;
a loose-fill cellulose insulation being filled and packed within said side thermal insulating cavity to provide a predetermined thermal insulating value
a strengthening panel received within a bottom portion of the outer box and positioned in adjacent facing relation with the bottom wall of the inner box;
said outer box bottom wall and sidewalls and said strengthening panel cooperating to form a bottom thermal insulating cavity,
a loose-fill cellulose insulation being filled and packed within said bottom thermal insulating cavity to provide a predetermined thermal insulating value; and
a lid assembly comprising a thermally insulated lid box having a bottom wall, a top wall and a plurality of sidewalls cooperating to define a thermal insulating lid cavity and a loose-fill cellulose insulation being filled and packed within said thermal insulating lid cavity to provide a predetermined thermal insulating value,
said lid assembly being received within said lid cavity, and
a PCM bladder configured and arranged to receive and retain a flowable phase change material preconditioned at a predetermined temperature,
said PCM bladder being removably received within the product cavity.
