Abstract

A collapsible box includes a plurality of side panels including a first side panel and a second side panel, each of the plurality of side panels defining a side panel top edge; a box bottom; and a box top comprising a plurality of top panels including a first top panel extending from the side panel top edge of the first side panel and a second top panel extending from the side panel top edge of the second side panel, the second top panel comprising an overlapping portion; wherein, in a folded-down configuration of the collapsible box: the first side panel confronts the second side panel; and the overlapping portion of the second top panel is folded over a top panel top edge of the first top panel.

First claim

That which is claimed is:

1. A collapsible box comprising:
a plurality of side panels including a first side panel and a second side panel, each of the plurality of side panels defining a side panel top edge;
a box bottom; and
a box top comprising a plurality of top panels comprising:
a first top panel extending from the side panel top edge of the first side panel, the first top panel supporting a superjacent panel pivotably connected at a first fold line, and a subjacent panel pivotably connected at a second fold line and pivotably connected to the superjacent panel; and
a second top panel extending from the side panel top edge of the second side panel, the second top panel comprising an overlapping portion;

wherein, in a folded-down configuration of the collapsible box:
the first side panel confronts the second side panel; and
the overlapping portion of the second top panel is folded over a top panel top edge of the first top panel.

2. The collapsible box of claim 1 , wherein:
the second top panel further comprises a connecting portion hingedly coupled to the side panel top edge of the second side panel by a top panel fold line; and
the overlapping portion is hingedly coupled to the connecting portion opposite the side panel top edge by a connecting-over fold line.

3. The collapsible box of claim 2 , wherein the connecting-over fold line is a double fold line comprising a pair of parallel fold lines.

4. The collapsible box of claim 2 , wherein:
the plurality of side panels further includes a third side panel and a fourth side panel;
the plurality of top panels further comprises a third top panel extending from the side panel top edge of the third side panel and a fourth top panel extending from the side panel top edge of the fourth side panel; and
the overlapping portion comprises an adhesive configured to adhere to the fourth top panel in an assembled and closed configuration of the collapsible box.

5. The collapsible box of claim 4 , wherein:
the overlapping portion defines a proximal portion coupled to the connecting portion and a distal end portion opposite the connecting portion;
the adhesive is applied to the distal end portion of the overlapping portion; and
the distal end portion is joined to the proximal portion by a tear strip.

6. The collapsible box of claim 5 , wherein:
the overlapping portion comprises a primary sealing flap and a secondary sealing flap;
each of the adhesive and the tear strip are arranged on the primary sealing flap; and
the secondary sealing flap comprises a secondary adhesive configured to adhere to the fourth top panel in a secondary assembled and closed configuration of the collapsible box.

7. The collapsible box of claim 1 , wherein:
the plurality of side panels further includes a third side panel and a fourth side panel;
the plurality of top panels further comprises a third top panel extending from the side panel top edge of the third side panel and a fourth top panel extending from the side panel top edge of the fourth side panel; and
in the folded-down configuration of the collapsible box:
the fourth side panel confronts the third side panel;
the first side panel is substantially coplanar with the fourth side panel; and
the second side panel is substantially coplanar with the third side panel.

8. The collapsible box of claim 7 , wherein:
each of the plurality of side panels define a side panel bottom edge opposite the side panel top edge;
the box bottom comprises a plurality of bottom panels including:
a first bottom panel hingedly extending from the side panel bottom edge of the first side panel;
a second bottom panel hingedly extending from the side panel bottom edge of the second side panel;
a third bottom panel hingedly extending from the side panel bottom edge of the third side panel; and
a fourth bottom panel hingedly extending from the side panel bottom edge of the fourth side panel;

the first bottom panel confronts the second bottom panel in the folded-down configuration of the collapsible box; and
the fourth bottom panel confront the third bottom panel in the folded-down configuration of the collapsible box.

9. The collapsible box of claim 8 , wherein, in the folded-down configuration of the collapsible box:
the first bottom panel and the second bottom panel are disposed between the first side panel and the second side panel; and
the fourth bottom panel and the third bottom panel are disposed between the fourth side panel and the third side panel.

10. The collapsible box of claim 9 , wherein:
a first glue area extends from one of the first bottom panel or the second bottom panel and is configured to attach to the other one of the first bottom panel or the second bottom panel in an assembled configuration of the collapsible box; and
a second glue area extends from one of the third bottom panel or the fourth bottom panel and is configured to attach to the other one of the third bottom panel or the fourth bottom panel in the assembled configuration of the collapsible box.

11. The collapsible box of claim 10 , wherein the first glue area extends from and is hingedly connected to the one of the first bottom panel or the second bottom panel at a first collapsing fold line, and wherein the second glue area extends from and is hingedly connected to the one of the third bottom panel or the fourth bottom panel at a second collapsing fold line.

12. The collapsible box of claim 7 , wherein a width of the overlapping portion is greater than a width of the first side panel, and wherein the overlapping portion is further folded over a top panel top edge of the fourth top panel.

13. The collapsible box of claim 1 , wherein the subjacent panel is pivotably connected to the superjacent panel at a third fold line.

14. The collapsible box of claim 1 , wherein:
the second top panel further comprises a connecting portion extending between the overlapping portion and the second side panel; and
the superjacent panel is pivotably connected to the connecting portion of the second top panel.

15. The collapsible box of claim 1 , wherein the collapsible box defines a rectangular outline in the folded-down configuration.
