Abstract

A telescoping insulated box assembly including an outer box including a plurality of outer side walls, the plurality of outer side walls including a first outer side wall including a first outer side panel, a first inner side panel, a first connecting strip, and a tab, the first connecting strip joined to a top of the first outer side panel by a first fold line and a top of the first inner side panel by a second fold line, the first outer side panel, the first inner side panel, and the first connecting strip at least partially defining a first insulation cavity within the first outer side wall, the tab joined to a side of the first inner side panel by a third fold line; and a second outer side wall including a second outer side panel, a second inner side panel, and a second connecting strip.

First claim

That which is claimed is:

1. A telescoping insulated box assembly, comprising:
an outer box comprising a plurality of outer side walls, the plurality of outer side walls comprising:
a first outer side wall comprising a first outer side panel, a first inner side panel, a first connecting strip, and a tab, the first connecting strip joined to a top of the first outer side panel by a first fold line and a top of the first inner side panel by a second fold line, the first outer side panel, the first inner side panel, and the first connecting strip at least partially defining a first insulation cavity within the first outer side wall, the tab joined to a side of the first inner side panel by a third fold line; and
a second outer side wall comprising a second outer side panel, a second inner side panel, and a second connecting strip, the second connecting strip joined to a top of the second outer side panel by a fourth fold line and a top of the second inner side panel by a fifth fold line, the second outer side panel, the second inner side panel, and the second connecting strip at least partially defining a second insulation cavity within the second outer side wall, the tab positioned between the second outer side panel and the second inner side panel; and

an inner box, the inner box comprising a plurality of inner side walls and an inner wall forming a portion of a top side of the box assembly, a first inner side wall of the plurality of inner side walls defining a third insulation cavity, the inner wall defining a fourth insulation cavity, the inner box sized to fit into the outer box such that each inner side wall of the plurality of inner side walls faces a different outer side wall of the plurality of outer side walls.

2. The box assembly of claim 1 , wherein:
the plurality of inner side walls comprises a first inner side wall and a second inner side wall;
the first inner side wall comprises a third inner side panel, a third outer side panel, and a second tab;
the third insulation cavity is defined between the third inner side panel and the third outer side panel;
the second tab is joined to the third inner side panel by a sixth fold line;
the second inner side wall comprises a fourth inner side panel and a fourth outer side panel;
the second tab is positioned between the fourth inner side panel and the fourth outer side panel; and
a fifth insulation cavity is defined between the fourth inner side panel and the fourth outer side panel.

3. The box assembly of claim 1 , wherein:
the outer box further comprises an outer bottom wall;
the outer bottom wall comprises an outer bottom panel joined to the first outer side panel by a sixth fold line and an inner bottom panel joined to the first inner side panel by a seventh fold line; and
a fifth insulation cavity is at least partially defined between the outer bottom panel and the inner bottom panel.

4. The box assembly of claim 1 , wherein the outer box further comprises an insulator pad positioned within the first insulation cavity.

5. The box assembly of claim 4 , wherein the insulator pad is repulpable.

6. The box assembly of claim 5 , wherein the outer box is repulpable.

7. The box assembly of claim 1 , wherein an outer panel of the inner wall of the inner box is positioned coplanar with the first connecting strip and the second connecting strip when the inner box is fit within the outer box.

8. The box assembly of claim 1 , wherein the first outer side panel is joined to the second outer side panel by a sixth fold line.

9. An insulated box assembly, comprising:
an outer box comprising a plurality of outer side walls defining an insulated box cavity, the plurality of outer side walls comprising:
a first outer side wall comprising a first outer side panel, a first inner side panel, and a tab, the first outer side panel and the first inner side panel at least partially defining a first insulation cavity within the first outer side wall, the tab joined to a side of the first inner side panel by a third fold line; and
a second outer side wall comprising a second outer side panel and a second inner side panel, the second outer side panel and the second inner side panel, at least partially defining a second insulation cavity within the second outer side wall, the tab positioned between the second outer side panel and the second inner side panel; and

an inner box positioned within the insulated box cavity.

10. The box assembly of claim 9 , wherein the first outer side wall further comprises a connecting strip joined to a top of the first outer side panel by a first fold line and a top of the first inner side panel by a second fold line.

11. The box assembly of claim 9 , wherein:
the outer box comprises a bottom wall;
the bottom wall comprises an inner bottom panel and an outer bottom panel; and
a third insulation cavity is defined at least partially between the inner bottom panel and the outer bottom panel.

12. The box assembly of claim 11 , wherein the inner bottom panel is joined to the first inner side panel by a first fold line, and wherein the outer bottom panel is joined to the first outer side panel by a second fold line.

13. The box assembly of claim 9 , 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.

14. The box assembly of claim 13 , 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.

15. The box assembly of claim 9 , wherein the first outer side panel is joined to the second outer side panel by a first fold line.

16. The box assembly of claim 9 , wherein the outer box further comprises an insulator pad positioned within the first insulation cavity.

17. The box assembly of claim 16 , wherein the insulator pad is repulpable.

18. The box assembly of claim 17 , wherein the outer box is repulpable.
