Abstract

A blank for a package configured to retain an article therein can be configured to be wrapped around the article to form a circumferential case around the article and have a longitudinal length longer than the article. The blank can be configured to define the circumferential case to include one or more inward protrusions at or near one or more ends of the circumferential case that is configured to extend into the circumferential case above and/or below the article to retain the article longitudinally.

First claim

What is claimed is:

1. A blank for a package configured to retain an article therein, the blank configured to be wrapped around the article to form a circumferential case around the article having a longitudinal length longer than the article, the blank comprising:
an outer flap; and
an inner flap configured to be adhered to the outer flap, wherein the blank is configured to define the circumferential case to include two inward protrusions in the inner flap, one at each end of the circumferential case, wherein the two inward protrusions are configured to extend into the circumferential case, to retain the article longitudinally, wherein the two inward protrusions are disposed in substantially similar circumferential position of the circumferential case.

2. The blank of claim 1 , wherein the blank is configured to form the circumferential case to have a polygonal tube shape having a polygonal cross-sectional shape.

3. The blank of claim 1 , wherein the blank is configured to form at least one latch and a receiver for each latch to latch the circumferential case around the article.

4. The blank of claim 1 , wherein the inner flap, comprising:
a plurality of inner flap hinges, wherein the plurality of inner flap hinges define a first inner panel and a second panel of the inner flap, wherein the first inner panel and second inner panel include one or more common cuts defined at last partially through each of the first inner panel and the second inner panel, and a plurality of secondary hinges defined in the first inner panel and the second inner panel from an edge of the inner flap to a respective common cut to define at least one push-in subpanel configured to form one or more of the two inward protrusions; and
the outer flap, comprising:
a plurality of outer flap hinges, wherein the plurality of outer flap hinges define a first outer panel and a second outer panel, wherein the first outer panel and the second outer panel define one or more apertures from or near an edge of the outer flap to provide a user access to each push-in subpanel when formed around the article to allow a user to selectively form the one or more inward protrusions.

5. The blank of claim 4 , wherein the plurality of inner flap hinges define a third inner panel, a fourth inner panel of the inner flap, and a fifth inner panel between the first, second, third, and fourth inner panels.

6. The blank of claim 5 , wherein the third panel includes a receiver defined therein and configured to receive a latch tab of the blank.

7. The blank of claim 6 , wherein the first and second outer panels include two apertures total defined therein, each aperture located on opposite sides of the outer flap to provide access to one or more subpanels to allow a user to selectively form at least one inward protrusion at each end of the circumferential case.

8. The blank of claim 7 , wherein the plurality of outer flap hinges define a fifth outer panel between the first, second, third, and fourth outer panels.

9. The blank of claim 8 , wherein the plurality of outer flap hinges define a sixth outer panel and a seventh outer panel extending from opposite lateral ends of the outer flap, wherein the sixth outer panel includes the latch tab extending therefrom, wherein the seventh outer panel includes a latch cut defined between the seventh outer panel and an adjacent panel and configured to allow the latch tab to be inserted through the latch cut to enter the receiver of the inner flap.

10. The blank of claim 9 , wherein the fifth inner panel is connected to the fifth outer panel at a flap hinge such that the inner flap can be folded over to mate with the outer flap.

11. The blank of claim 10 , wherein the inner flap is configured to be adhered to the outer flap such that each push-in subpanel is accessible through an aperture of the outer flap.

12. The blank of claim 9 , wherein the inner flap is configured to be adhered to the outer flap such that at least one panel of the inner flap is attached to at least one panel of the outer flap.

13. The blank of claim 12 , wherein the inner flap is configured to be adhered to the outer flap.

14. The blank of claim 1 , wherein one of the inward protrusions is configured to be above the article and one of the inward protrusions is configured to be below the article when the blank is formed around the article.

15. A blank for a package configured to retain an article therein, the blank configured to be wrapped around the article to form a circumferential case around the article having a longitudinal length longer than the article, wherein the blank is configured to define the circumferential case to include two inward protrusions, one at each end of the circumferential case, wherein the two inward protrusions are configured to extend into the circumferential case, to retain the article longitudinally the blank comprising:
a flap having a plurality of hinges that define a plurality of panels, and a structure panel configured to attach to at least one of the plurality of panels when the structure panel is folded over at an adjacent hinge of the plurality of hinges, the structure panel including one or more inward protrusion panels defined by one or more cuts therein and configured to form one or more inward protrusions across the circumferential case when the flap is wrapped around the article to automatically retain the article longitudinally upon forming of the circumferential case.

16. The blank of claim 15 , wherein the structure panel includes at least two cuts total, at least one on each longitudinal side of the flap to form at least one inner protrusion panel on each longitudinal end of the circumferential case.

17. The blank of claim 16 , wherein the structure panel includes a plurality of midsection panels and a latch tab defined between two inward protrusion panels.

18. The blank of claim 16 , wherein one of the inward protrusions is configured to be above the article and one of the inward protrusions is configured to be below the article when the blank is formed around the article.

19. The blank of claim 15 , wherein the at least one panel of the plurality of panels defines an attachment tab extending outward therefrom, wherein a first cut receiver is defined in a hinge adjacent to the structure panel for the attachment tab to be inserted therethrough and retained thereby, wherein a second cut receiver is defined in an hinge adjacent to the at least one panel for the latch tab to be inserted therethrough and retained thereby.

20. The blank of claim 15 , wherein the two inward protrusion panels are retained against an inner circumference of the circumferential case without adhesive.

21. The blank of claim 15 , wherein the at least one panel of the plurality of panels includes an attachment portion extending therefrom, the attachment portion including one or more wing panels forming a respective clearance between an inner edge of the one or more wing panels and an outer edge of the at least one panel of the plurality of panels, wherein the two inward protrusion panels are held within the respective clearance when the flap is wrapped around the article.

22. The blank of claim 21 , wherein a portion of the structure panel overlaps a portion of the at least one panel of the plurality of panels when the attachment tab is attached to the at least one panel of the plurality of panels, wherein the portion of the structure panel is adhered to the portion of the at least one panel.
