Abstract

A blank assembly for forming a folded-cap container includes a first blank of sheet material that includes a pair of end panels, a pair of side panels, and a plurality of corner panels connected in series along a plurality of fold lines. Each of the end panels and side panels has a bottom edge that is substantially aligned with the respective bottom edges of the other end panels and side panels. Also, each of the four corner panels has a bottom free edge that is offset towards a central horizontal axis of the first blank from the bottom edges of the end panels and side panels. The blank assembly also includes a second blank of sheet material that includes a top panel and a lifting panel connected by a fold line. The top panel is configured to be coupled adjacent to a top edge of one of the end panels.

First claim

What is claimed is:

1. A blank assembly for forming a folded-cap container, said blank assembly comprising:
a first blank of sheet material comprising a pair of end panels, a pair of side panels, and a plurality of corner panels connected in series along a plurality of fold lines, wherein each of the pair of end panels and the pair of side panels has a bottom edge that is substantially aligned with the respective bottom edges of the others of the pair of end panels and the pair of side panels, and each of the four corner panels has a bottom free edge that is offset towards a central horizontal axis of the first blank from the bottom edges of the pair of end panels and the pair of side panels; and
a second blank of sheet material comprising a top panel and a lifting panel connected by a fold line,
wherein the top panel is configured to be coupled adjacent to a top edge of one of the pair of end panels of the first blank, and
wherein the lifting panel is configured to be folded downward from the fold line and positioned against an outward facing surface of one of the pair of end panels of the first blank when the folded-cap container is formed.

2. The blank assembly in accordance with claim 1 , wherein each panel of the pair of end panels and the pair of side panels has a pair of oppositely disposed free edges proximate to the bottom edge of the panel, each free edge is substantially aligned with one of the plurality of fold lines.

3. The blank assembly in accordance with claim 1 , wherein the first blank further comprises a pair of bottom side panels each extending from the bottom edge of a respective one of the pair of side panels, each bottom side panel comprises a pair of oppositely disposed projections, each projection extends parallel to the central horizontal axis such that a width of each bottom side panel is greater than a width of the respective side panel.

4. The blank assembly in accordance with claim 1 , wherein the first blank further comprises a top end panel extending from the top edge of the one of the pair of end panels, the top panel of the second blank is configured to be coupled to the top end panel.

5. The blank assembly in accordance with claim 4 , wherein the first blank further comprises a pair of top side panels each extending from a top edge of a respective one of the pair of side panels, the top edges of the side panels are substantially aligned, the top edge of the one of the pair of end panels is offset from the top edges of the side panels.

6. The blank assembly in accordance with claim 1 , wherein the top panel of the second blank includes a plurality of corner edges, a length of each corner edge is substantially equal to a width of each of the plurality of corner panels.

7. The blank assembly in accordance with claim 1 , wherein the second blank is formed from a triple-ply corrugated paperboard material.

8. The blank assembly in accordance with claim 1 , wherein the first blank is formed from a double-ply corrugated paperboard material.

9. A folded-cap container formed from a first blank of sheet material and a second blank of sheet material, the folded-cap container comprising:
a pair of end walls and a pair of side walls, each of the pair of end walls and the pair of side walls includes at least one panel of the first blank, each of the pair of end walls and the pair of side walls extends a first distance from a top end to a bottom end; a plurality of corner walls, each corner wall includes at least one panel of the first blank, each corner wall extends between one of the pair of end walls and one of the pair of side walls, each corner wall extends a second distance from the top end to a bottom free edge, wherein the second distance is shorter than the first distance; and
a top wall disposed proximate the top end that includes a top panel of the second blank, wherein a lifting panel extends from the top panel and is folded downward over a top end of one of the pair of end walls and against an outward facing surface of said end wall.

10. The folded-cap container in accordance with claim 9 , further comprising a plurality of gaps defined proximate to the bottom end, each gap is defined between one of the pair of end walls and one of the pair of side walls.

11. The folded-cap container in accordance with claim 10 , wherein each gap is at least partially defined by a bottom free edge of one of a plurality of corner panels of the first blank, a free edge of one of a pair of side panels of the first blank, and a free edge of one of a pair of end panels of the first blank.

12. The folded-cap container in accordance with claim 9 , wherein the pair of end walls, pair of side walls, and plurality of corner walls define a cavity, the folded-cap container further comprises a base inserted within the cavity proximate to the bottom end.

13. The folded-cap container in accordance with claim 12 , wherein the base includes a plurality of corners, each corner extends through a corresponding one of a plurality of gaps, each gap is defined proximate to the bottom end between one of the pair of end walls and one of the pair of side walls.

14. The folded-cap container in accordance with claim 13 , further comprising a bottom wall formed from a plurality of bottom panels, each bottom panel emanates from one wall of the pair of end walls and the pair of side walls, each gap is further defined by a respective one of the bottom panels emanating from the pair of end walls and a respective one of the bottom panels emanating from the pair of side walls.

15. The folded-cap container in accordance with claim 9 , wherein one of the pair of end walls includes one end panel of a pair of end panels of the first blank, a top end panel extends from the one end panel, the top panel of the second blank is coupled to the top end panel.

16. A method for forming a container from a first blank of sheet material and a second blank of sheet material, the method comprising:
rotating a pair of end panels, a pair of side panels, and a plurality of corner panels of the first blank about a plurality of fold lines to form a pair of end walls, a pair of side walls, and a plurality of corner walls, wherein each of the pair of end walls and the pair of side walls extends a first distance from a top end to a bottom end, each corner wall extends a second distance from the top end to a bottom free edge, and the second distance is shorter than the first distance; and
forming a top wall proximate the top end of the container by: coupling a top panel of the second blank to a top end panel of the first blank, wherein a lifting panel extends from the top panel, and wherein the top end panel extends from a top edge of one end panel of the pair of end panels; and
rotating the top end panel about a fold line at the top edge of the one end panel.

17. The method in accordance with claim 16 , wherein the pair of end walls, the pair of side walls, and the plurality of corner walls define a cavity, the method further comprises inserting a base within the cavity proximate to the bottom end.

18. The method in accordance with claim 17 , wherein the base includes a plurality of corners, and inserting the base within the cavity comprises inserting the base such that each corner extends through a corresponding one of a plurality of gaps, each gap is defined proximate to the bottom end between one of the pair of end walls and one of the pair of side walls.

19. The method in accordance with claim 16 , wherein rotating the pair of end panels, the pair of side panels, and the plurality of co
