Abstract

A telescoping insulated box assembly, comprising: an outer box, the outer box comprising a side wall and a bottom wall, the side wall and the bottom wall of the outer box each defining an insulation cavity; and an inner box, the inner box comprising a side wall and a wall forming a portion of a top side of the box assembly, each wall of the inner box defining an insulation cavity, the inner box sized to fit into the outer box such that the each of the side walls of the inner box faces one of the side walls of the outer box.

First claim

That which is claimed is:

1. A telescoping insulated box assembly, comprising:
an outer box, the outer box comprising a side wall and a bottom wall, the side wall and the bottom wall of the outer box each defining an insulation cavity;
an inner box, the inner box comprising a side wall and a wall forming a portion of a top side of the box assembly, each wall of the inner box defining an insulation cavity, the inner box sized to fit into the outer box such that the each of the side walls of the inner box faces one of the side walls of the outer box; and
a handle attached to the inner box on the wall forming the portion of the top side of the box assembly.

2. The box assembly of claim 1 , wherein:
the side wall of the outer box comprises
an outer side panel;
a connecting strip joined to the outer side panel by a fold line; and
an inner side panel joined to the connecting strip by a fold line; and
wherein the outer side panel, the connecting strip, and the inner side panel define the insulation cavity therebetween.

3. The box assembly of claim 2 , wherein:
the bottom wall of the outer box comprises
an outer bottom panel joined to the outer side panel by a fold line; and
an inner bottom panel joined to the inner side panel by a fold line;
wherein the insulation cavity is a first insulation cavity; and
wherein the outer bottom panel and the inner bottom panel define a second insulation cavity therebetween.

4. The box assembly of claim 1 , wherein:
the side wall of the inner box comprises
an outer side panel;
a connecting strip joined to the outer side panel by a fold line; and
an inner side panel joined to the connecting strip by a fold line; and
wherein the outer side panel, the connecting strip, and the inner side panel define the insulation cavity therebetween.

5. The box assembly of claim 4 , wherein:
the wall of the inner box forming a portion of a top side of the box assembly wall is a bottom wall during assembly of the inner box, the bottom wall of the inner box comprising
an outer bottom panel joined to the outer side panel by a fold line; and
an inner bottom panel joined to the inner side panel by a fold line;
wherein the insulation cavity is a first insulation cavity; and
wherein the outer bottom panel and the inner bottom panel define a second insulation cavity therebetween.

6. The box assembly of claim 1 , wherein the insulation cavity of the bottom wall of the outer box is filled with a repulpable insulator pad.

7. The box assembly of claim 1 , wherein the insulation cavity of the side wall of the outer box is filled with a repulpable insulator pad.

8. The box assembly of claim 1 , wherein the outer box comprises four side walls, each side wall comprising
an outer side panel;
a connecting strip joined to the outer side panel by a fold line; and
an inner side panel joined to the connecting strip by a fold line; and
wherein the outer side panels, the connecting strips, and the inner sides panel define the insulation cavities therebetween.

9. The box assembly of claim 8 , wherein the outer box comprises a side tab joined by a fold line to at least one of the inner side panels, the side tab covered by an inner side panel of an adjacent side wall such that the side tab is inside one of the insulation cavities.

10. The box assembly of claim 1 , wherein the handle comprises adhesive ends, the adhesive ends configured to secure a plurality of outer bottom panels of the inner box to form the wall of the inner box forming the portion of the top side of the box assembly.

11. The box assembly of claim 1 , further comprising an access tab attached to the outer box and covering a corner of the inner box, such that the inner box is secured inside the outer box.

12. The box assembly of claim 11 , wherein the access tab defines a cut and a perforation such that tearing the perforation opens up the cut and exposes the corner of the inner box, allowing the inner box to telescope out of the outer box.

13. A method of assembling a telescoping insulated box assembly, comprising:
assembling an outer box by folding an inner side panel into the outer box, the inner side panel joined to a connecting strip by a fold line, the connecting strip joined to an outer side panel by a fold line, the outer side panel, the connecting strip, and the inner side panel forming a side wall and defining an insulation cavity therebetween;
assembling an inner box by folding an inner side panel of the inner box into the inner box, the inner side panel joined to a connecting strip by a fold line, the connecting strip joined to an outer side panel by a fold line, the outer side panel, the connecting strip, and the inner side panel forming a side wall and defining an insulation cavity of the inner box therebetween;
inserting the inner box into the outer box, such that an open top of the inner box is proximate a bottom of the outer box, and a bottom of the inner box forms a portion of a top side of the box assembly; and
attaching a handle to the inner box, the handle configured to allow the inner box to be pulled out of the outer box.

14. The method of claim 13 , wherein the insulation cavity of the outer box is a first insulation cavity of the outer box, and wherein the method further comprises:
folding at least two outer bottom panels of the outer box;
folding at least two inner bottom panels of the outer box;
forming a second insulation cavity between the inner bottom panels and the outer bottom panels;
and placing a plurality of insulator pads in the first and second insulation cavities.

15. The method of claim 13 , further comprising
folding a side tab, the side tab joined by a fold line to one of the inner side panels, behind an inner side panel of an adjacent side wall, such that the inner side panel joined to the side tab is restricted from folding up.

16. The method of claim 13 , further comprising placing a repulpable insulator pad in the insulation cavity of at least one of the outer box or the inner box.

17. The method of claim 13 , wherein the outer box comprises four inner side panels, four connecting strips, and four outer side panels, the side panels, the connecting strips, and the outer side panels defining four side walls, and wherein four portions of the insulation cavity are defined within the four side walls.

18. The method of claim 17 , further comprising wrapping a single insulator pad around the four inner side panels inside the insulation cavity.
