Abstract

An insulated box assembly comprising an outer box comprising a plurality of outer lateral sidewalls, the outer lateral sidewalls defining an inner surface, the inner surface defining an inner cavity; an inner box comprising a plurality of inner lateral sidewalls, the inner box received in the inner cavity, the inner lateral sidewalls defining an outer surface; a sidewall liner received in the inner cavity between the outer lateral sidewalls and the inner lateral sidewalls, the sidewall liner defining a liner outer surface and a liner inner surface opposite the liner outer surface; and a lid assembly disposed within the inner cavity, the lid assembly comprising a lid box and a lid liner.

First claim

That which is claimed is:

1 . An insulated box assembly comprising:
an outer box comprising a plurality of outer lateral sidewalls, the outer lateral sidewalls defining an inner surface and a plurality of vertical outer edges, the inner surface defining an inner cavity; an inner box comprising a plurality of inner lateral sidewalls, the inner box received in the inner cavity, the inner lateral sidewalls defining an outer surface; a sidewall liner received in the inner cavity between the outer lateral sidewalls and the inner lateral sidewalls, the sidewall liner defining a liner outer surface and a liner inner surface opposite the liner outer surface, the liner outer surface defining at least one curved outer bend and facing the inner surface of the outer lateral sidewalls so that a curved outer bend of the at least one curved outer bend is bent into a corresponding vertical outer edge of the plurality of vertical outer edges, and the liner inner surface facing the outer surface of the inner lateral sidewalls; and a lid assembly disposed within the inner cavity, the lid assembly comprising a lid box and a lid liner, wherein
the sidewall liner is bent to define a plurality of lateral liner sides, each of the lateral liner sides oriented between a corresponding one of the inner lateral sidewalls and a corresponding one of the outer lateral sidewalls, and
the liner inner surface defines a curved inner bend between each adjacent pair of the lateral liner sides, and the liner outer surface defines a curved outer bend between each adjacent pair of the lateral liner sides, wherein the curved inner bends confront the inner lateral sidewalls and the curved outer bends confront the outer lateral sidewalls.

2 . The insulated box assembly of claim 1 , wherein a portion of the lid box is disposed between the lid liner and the sidewall liner, such that the lid liner is not in contact with the sidewall liner.

3 . The insulated box assembly of claim 1 , wherein the lid liner received is within the lid box, the lid box supported proximate a top end of the sidewall liner and disposed within the inner cavity.

4 . The insulated box assembly of claim 3 , wherein the inner box comprises at least one top flap folded over the top end of the sidewall liner, the at least one top flap disposed between the lid box and the monolithic sidewall liner.

5 . The insulated box assembly of claim 1 , wherein the liner inner surface is fastened to at least one of the inner lateral sidewalls to secure the sidewall liner thereto.

6 . The insulated box assembly of claim 1 , wherein;
the inner lateral sidewalls define an inner surface opposite the outer surface; and the inner surface of the inner lateral sidewalls defines a storage hollow configured to receive contents therein.

7 . The insulated box assembly of claim 1 , wherein each of the inner lateral sidewalls comprises corrugated fiberboard.

8 . The insulated box assembly of claim 1 , wherein the sidewall liner comprises a first end and a second end.

9 . The insulated box assembly of claim 8 , wherein the first end is folded towards the second end to wrap the sidewall liner around the inner lateral sidewalls.

10 . The insulated box assembly of claim 1 , wherein:
each of the curved outer bends is oriented at a corresponding one of the vertical outer edges; the plurality of inner lateral sidewalls define a plurality of vertical inner edges; and each of the curved inner bends is oriented at a corresponding one of the vertical inner edges.

11 . The insulated box assembly of claim 1 , further comprising a bottom wall liner, the bottom wall liner defining a top liner surface and a bottom liner surface.

12 . The insulated box assembly of claim 11 , wherein:
the sidewall liner defines a top end and a bottom end opposite the top end; and the bottom end of the sidewall liner faces the top liner surface of the bottom wall liner.

13 . A method of assembling an insulated box assembly comprising:
obtaining an outer box defining a plurality of vertical outer edges and an inner cavity, an inner box defining a storage hollow, and an insulating lining comprising a resilient sidewall liner, the resilient sidewall liner defining a liner outer surface defining at least one curved outer bend and a liner inner surface; positioning the resilient sidewall liner around the inner box to form an inner box assembly; inserting the inner box assembly into the inner cavity of the outer box, the resilient sidewall liner oriented between the inner box and the outer box, the liner outer surface facing the outer box, the inner box comprising a plurality of inner lateral sidewalls; and inserting a lid assembly into the inner cavity of the outer box, the lid assembly comprising a lid box and a lid liner, wherein
the at least one curved outer bend of the resilient sidewall liner is bent into a corresponding vertical outer edge of the outer box,
the resilient sidewall liner defines a first end and a second end, and positioning the resilient sidewall liner around the inner box comprises positioning the first end adjacent to the second end so that the liner inner surface faces the inner box, and
wrapping the resilient sidewall liner around the inner box comprises bending the resilient sidewall liner to define a plurality of lateral liner sides, the liner inner surface defining a curved inner bend between each adjacent pair of the lateral liner sides.

14 . The method of claim 13 , wherein the lid liner is received within the lid box, the lid box is supported proximate a top end of the resilient sidewall liner, and a portion of a lid box is disposed between the lid liner and the resilient sidewall liner such that the lid liner is not in contact with the resilient sidewall liner.

15 . The method of claim 14 , wherein the inner box comprises at least one top flap folded over the top end of the resilient sidewall liner, each top flap disposed between the lid box and the resilient sidewall liner.
