Abstract

A method of forming a packaging blank includes stripping away a portion of a stock material to create an offset void (24, 25) and blanking the stock material into a plurality of packaging blanks. Blanking includes separating the stock material along a plurality of severance lines (26, 28, 29) dividing between the blanks (100), wherein at least two of the severance lines are separated from one another by the offset void. Blanking can include separating the stock material along a plurality of severance lines dividing the blanks from one another by a blanking grid, wherein the blanking grid is arranged in a nested sheet-fed layout.

First claim

What is claimed is:

1. A blank for forming a packaging container, the blank comprising a plurality of panels for forming the container, the plurality of panels including a first side panel, a first end panel, a bottom panel and a riser panel, the first side panel comprising first and second opposed end edges and a lower edge, the first end panel being connected by a fold line to the first end edge of the first side panel, the riser panel being connected by a fold line to the first end panel, wherein the bottom panel is connected by a fold line to the lower edge of the first side panel such that first and second opposed end edges of the bottom panel are located next to the first and second end edges of the first side panel respectively, wherein the plurality of panels further includes a second end panel connected by a fold line to the second end edge of the first side panel, and wherein the bottom panel is not symmetrically centered relative to the first side panel such that the bottom panel is disposed closer to the first end panel than to the second end panel, wherein the first side panel has a width defined between said first and second opposed end edges of the first side panel, wherein the bottom panel has a width defined between said first and second opposed end edges of the bottom panel, wherein the width of the bottom panel is less than the width of the first side panel, wherein the bottom panel is free of connection to any other part of the blank other than the first side panel.

2. A blank according to claim 1 wherein the bottom panel is disposed closer to the first end edge of the first side panel than to the second end edge of the first side panel.

3. A blank according to claim 1 wherein the first end edge of the bottom panel is closer to the riser panel than the second end edge of the bottom panel.

4. A blank according to claim 1 wherein the bottom panel is not symmetrically centered relative to the first side panel such that the bottom panel is connected to a first part of the lower edge of the first side panel, the first part of the lower edge being closer to the first end edge of the first side panel than to the second end edge of the first side panel.

5. A blank according to claim 4 wherein the lower edge of the first side panel has a second part which is free of any connection to any other part of the blank.

6. A blank according to claim 1 , wherein the plurality of panels further includes a primary partition panel connected by a fold line to the second end panel.

7. A blank according to claim 6 wherein the plurality of panels further includes a lateral partition panel connected by a fold line to the primary partition panel.

8. A blank according to claim 6 wherein the riser panel is adhered to the primary partition panel when the blank is set up into the container.

9. A blank according to claim 6 wherein the plurality of panels further includes a handle panel connected to the primary partition panel and wherein the primary partition panel has a handle opening.

10. A packaging container comprising a plurality of panels defining an interior volume for receiving articles, including first and second side panels, first and second end panels and a bottom panel, the packaging container further comprising a riser panel, wherein the first side panel comprises first and second opposed end edges and a lower edge, the first end panel being connected by a fold line to the first end edge of the first side panel, the second end panel being connected by a fold line to the second end edge of the first side panel, the riser panel being connected by a fold line to the first end panel, wherein the bottom panel is connected by a fold line to the lower edge of the first side panel such that first and second opposed end edges of the bottom panel are located next to the first and second end panels respectively, wherein the bottom panel is not symmetrically centered relative to the first side panel such that the bottom panel is disposed closer to the first end panel than to the second end panel, wherein the first side panel has a width defined between said first and second opposed end edges of the first side panel, wherein the bottom panel has a width defined between said first and second opposed end edges of the bottom panel, wherein the width of the bottom panel is less than the width of the first side panel, wherein the bottom panel is free of integral connection to any other part of the packaging container other than the first side panel.

11. A packaging container according to claim 10 wherein the first end edge of the bottom panel is closer to the riser panel than the second end edge of the bottom panel.

12. A packaging container according to claim 10 wherein the bottom panel is not symmetrically centered relative to the first side panel such that the bottom panel is connected to a first part of the lower edge of the first side panel, the first part of the lower edge being closer to the first end panel than to the second end panel.

13. A packaging container according to claim 12 wherein the lower edge of the first side panel has a second part which is free of any connection to any other part of the packaging container, and wherein the second part is disposed between the first part and the second end panel.

14. A packaging container according to claim 10 wherein the first side panel has a width defined as the distance between first and second end edges thereof, and wherein the bottom panel has a width defined as the distance between first and second opposed end edges thereof, and wherein the width of the bottom panel is less than the width of the first side panel.

15. A packaging container according to claim 10 , further comprising a primary partition panel connected by a fold line to the second end panel and a lateral partition panel connected by a fold line to the primary partition panel.

16. A packaging container according to claim 15 wherein the riser panel is adhered to the primary partition panel.

17. A packaging container according to claim 15 further comprising a handle panel connected to the primary partition panel and wherein the primary partition panel has a handle opening.
