Abstract

A carton includes a front panel, a back panel and a side panel. End panels are respectively foldably connected to the front and back panels for at least partially closing an end of the carton, and a web panel is foldably connected to each of the side panel and the end panels. The web panel may be folded away from the end of the carton and be connected to the outer surface of the side panel. The folding of the web panel tensions the end panels and pinches respective panels of the carton together to at least partially seal the end of the carton that is closed by the end panels.

is foldably connected to the end edge of the second wall panel; and

a third wall panel positioned across the interior of the carton from the second wall panel and having

a longitudinally extending edge foldably connected to the second longitudinally extending edge of the first wall panel, and

an end edge extending crosswise to the longitudinally extending edge of the third wall panel, wherein the second end panel has a second edge that

extends crosswise the first edge of the second end panel, and

is foldably connected to the end edge of the third wall panel.

6. The carton according to claim 5, wherein the second end panel extends substantially completely to both the end edge of the second wall panel and the second edge of the first end panel.

7. The carton according to claim 5, wherein:

the first wall panel includes

an interior surface facing towards the interior of the carton, and

an outer surface that is opposite from the interior surface; and

the web panel at least partially covers the outer surface of the first wall panel; and

the first portion of the web panel is positioned between the second and third portions of the web panel and the outer surface of the first wall panel.

8. The carton according to claim 5, wherein the first end panel extends at least about half way across the end of the carton in the direction extending along both the third edge of the web panel and the end edge of the first wall panel.

9. The carton according to claim 8, wherein the first end panel extends more than half way across the end of the carton in the direction extending along both the third edge of the web panel and the end edge of the first wall panel.

10. The carton according to claim 9, wherein the first end panel extends substantially completely to both the end edge of the third wall panel and the second edge of the second end panel.

11. The carton according to claim 1, wherein:

the carton is erected from a blank having a plurality of peripheral edges that define an outermost periphery of the blank while the blank is in an unerected, flat state;

the web panel includes a fourth edge that

is opposite from the third edge of the web panel, and

extends crosswise to the first and second edges of the web panel; and

the fourth edge of the web panel is at least one of the plurality of peripheral edges that define the outermost periphery of the blank.

12. The carton according to claim 11, wherein:

the web panel includes first and second oblique fold lines that extend obliquely relative to each of the first, second, third and fourth edges of the web panel;

the oblique fold lines extend from proximate the fourth edge of the web panel, which is the at least one of the plurality of peripheral edges that define the outermost periphery of the blank, divergently with respect to one another toward the third edge of the web panel; and

the oblique fold lines extend substantially completely to the fourth edge of the web panel, which is the at least one of the plurality of peripheral edges that define the outermost periphery of the blank.

13. A blank for being erected into a carton, the blank comprising:

a plurality of peripheral edges that define an outermost periphery of the blank;

a web panel including

opposite first and second longitudinally extending edges,

opposite first and second transversely extending edges that extend transversely to the first and second longitudinally extending edges,

oblique fold lines extending obliquely relative to each of the first and second longitudinally extending edges and the first and second transversely extending edges, wherein

the oblique fold lines extend substantially completely to the second transversely extending edge, and

the second transversely extending edge is at least one of the plurality of peripheral edges that define the outermost periphery of the blank; and

first and second end panels for at least partially closing an end of the carton when the carton is erected from the blank, wherein

the web panel is positioned between the first and second end panels,

the first end panel has a longitudinally extending edge foldably connected to the first longitudinally extending edge of the web panel, and

the second end panel has a longitudinally extending edge foldably connected to the second longitudinally extending edge of the web panel.

14. The blank according to claim 13, wherein the web panel includes first, second and third portions that are respectively at least partially defined by the oblique fold lines, the first and second longitudinally extending edges of the web panel, and the first and second transversely extending edges of the web panel.

15. The blank according to claim 13, comprising a plurality of wall panels for at least partially extending around an interior of the carton when the carton is erected from the blank, the plurality of wall panels including:

there is an overlapping relationship between the second and third panels; and

at least partially sealing the end of the carton, comprising folding the first panel away from the end of the carton, wherein the second and third panels are tensioned and urged together in response to the folding of the first panel away from the end of the carton.

17. The method according to claim 16, wherein the second panel substantially closes the end of the carton.

18. The method according to claim 16, wherein simultaneously with the inwardly folding of the second and third panels:
