Abstract

In general, one aspect of the disclosure is generally directed to a construct for supporting at least one article. The construct can comprise at least a panel and a plurality of stiffening features. The plurality of stiffening features can comprise a pattern of bosses formed in the panel. The pattern of bosses can be configured for at least partially reducing buckling of the panel.

First claim

What is claimed is:

1. A construct for supporting at least one article, the construct comprising:
at least a panel; and
a plurality of stiffening features comprising a pattern of bosses formed in the panel, the pattern of bosses being configured for at least partially reducing buckling of the panel,
the pattern of bosses comprising:
at least one emboss and at least one deboss, wherein
the at least one emboss is spaced apart from the at least one deboss by a neutral area of the panel, the neutral area of the panel comprising a first planar surface extending between the at least one emboss and the at least one deboss and extending to an outer edge of the panel,
the at least one emboss is at least partially defined by an emboss edge,
the at least one deboss is at least partially defined by a deboss edge,
an entirety of the emboss edge abutting the neutral area and extending from the first planar surface to a second planar surface in a first direction, the emboss edge comprising an outer peripheral emboss edge portion, an inner peripheral emboss edge portion, a first curved radial emboss edge end, and a second curved radial emboss edge end, the first curved radial emboss edge end and the second curved radial emboss edge end each connecting the outer peripheral emboss edge portion and the inner peripheral emboss edge portion, and
an entirety of the deboss edge abutting the neutral area and extending from the first planar surface to a third planar surface in a second direction, the deboss edge comprising an outer peripheral deboss edge portion, an inner peripheral deboss edge portion, a first curved radial deboss edge end, and a second curved radial deboss edge end, the first curved radial deboss edge end and the second curved radial deboss edge end each connecting the outer peripheral deboss edge portion and the inner peripheral deboss edge portion, the second direction being opposite the first direction, and
the first planar surface extending between the first curved radial emboss edge and the first curved radial deboss edge.

2. The construct of claim 1 , wherein at least one of the emboss edge and the deboss edge extends perpendicular to the neutral area of the panel.

3. The construct of claim 1 , wherein the emboss edge extends around a perimeter of the at least one emboss and the deboss edge extends around a perimeter of the at least one deboss.

4. The construct of claim 1 , wherein each of the edges is curved.

5. The construct of claim 1 , wherein the panel comprises a grain direction, and at least a majority of each of the edges is nonparallel with the grain direction.

6. The construct of claim 1 , wherein the pattern of bosses comprises a plurality of emboss features and a plurality of deboss features.

7. The construct of claim 6 , wherein the deboss features of the plurality of deboss features are interspersed with the emboss features of the plurality of emboss features.

8. The construct of claim 1 , wherein each of the bosses of the pattern of bosses comprises a curved segment.

9. The construct of claim 8 , wherein the curved segments are disposed in at least one elliptical arrangement in the panel.

10. The construct of claim 8 , wherein the curved segments are disposed in at least one semielliptical arrangement in the panel.

11. The construct of claim 8 , wherein the curved segments are disposed in at least one semielliptical arrangement adjacent and in at least one elliptical arrangement in the panel.

12. The construct of claim 1 , wherein each of the bosses of the pattern of bosses comprises a circle.

13. The construct of claim 12 , wherein the circles are arranged in at least a first row and a second row, the first row being generally offset from the second row.

14. The construct of claim 1 , wherein each of the bosses of the pattern of bosses comprises an elongate curve.

15. The construct of claim 14 , wherein each of the elongate curves comprises a radius of curvature, and the elongate curves are arranged in the blank so that each elongate curve has a generally opposing radius of curvature relative to the radius of curvature of an adjacent one of the elongate curves.

16. The construct of claim 1 , wherein each of the bosses of the pattern of bosses comprises a generally longitudinal segment or a generally lateral segment.

17. The construct of claim 16 , wherein at least one of the generally longitudinal segments extends between respective ends of two of the generally lateral segments.

18. The construct of claim 1 , wherein each of the bosses of the pattern of bosses comprises a generally longitudinal segment, a generally lateral segment, or an oblique segment.

19. The construct of claim 18 , wherein each of the oblique segments extends from an end of one of the generally longitudinal segments to an end of one of the generally lateral segments.

20. The construct of claim 18 , wherein the generally longitudinal segments, the generally lateral segments, and the oblique segments are arranged in a plurality of generally concentric polygonal shapes.

21. The construct of claim 1 , wherein the construct is formed from a blank.

22. The construct of claim 1 , wherein the construct is a tray.

23. The construct of claim 1 , wherein the construct comprises at least one flap foldably connected to the panel.

24. The construct of claim 1 , wherein the construct comprises paperboard.

25. The construct of claim 1 , wherein the first planar surface of the panel surrounds the entire perimeter of the at least one emboss and the at least one deboss.

26. The construct of claim 1 , wherein the first planar surface abuts the emboss edge around the entire perimeter of the at least one emboss and the first planar surface abuts the deboss edge around the entire perimeter of the at least one deboss.

27. The construct of claim 1 , wherein the outer edge is one of a plurality of outer edges of the panel, the first planar surfaced extending to each of the plurality of outer edges of the panel.

28. A method of forming a construct, the method comprising:
obtaining a web of material comprising at least a panel; and
forming a plurality of stiffening features in the panel comprising forming a pattern of bosses in the panel for at least partially reducing buckling of the panel,
the pattern of bosses comprising:
at least one emboss and at least one deboss, wherein
the at least one emboss is spaced apart from the at least one deboss by a neutral area of the panel, the neutral area of the panel comprising a first planar surface extending between the at least one emboss and the at least one deboss and extending to an outer edge of the panel,
the at least one emboss is at least partially defined by an emboss edge,
the at least one deboss is at least partially defined by a deboss edge,
an entirety of the emboss edge abutting the neutral area and extending from the first planar surface to a second planar surface in a first direction, the emboss edge comprising an outer peripheral emboss edge portion, an inner peripheral emboss edge portion, a first curved radial emboss edge end, and a second curved radial emboss edge end, the first curved radial emboss edge end and the second curved radial emboss edge end each connecting the outer peripheral emboss edge portion and the inner peripheral emboss edge portion, and
an entirety of the deboss edge abutting the neutral area and extend
