A paperboard carton doubles as a shipping container for articles such as beverage cans and a cooler for containing ice to cool the articles when the carton is opened. The top portion of the carton is breached by removing an opening strip defined by zipper rules. Once breached, the tops and side panels of the carton are opened up to form an upwardly open chimney or skirt into which ice can be placed to cool the contents of the carton. Gussets formed in the lower corners of the cartons insure that water from melting ice does not leak prematurely from the carton.

The method of claim 1, wherein gluing the blank to form a tubular structure comprises: forming a top panel at least from the first top panel and the second top panel,adhering the first top panel to the second top panel;adhering the at least one first top flap to the at least one third top flap; andadhering the at least one second top flap to the at least one fourth top flap. 3. The method of claim 2, wherein the carton blank further comprises: at least one first side panel flap foldably connected to a first end of the first side panel at a fifth longitudinal fold line;at least one second side panel flap foldably connected to a second end of the first side panel at a sixth longitudinal fold line;at least one third side panel flap foldably connected to a first end of the second side panel at a seventh longitudinal fold line;at least one fourth side panel flap foldably connected to a second end of the second side panel at an eighth longitudinal fold line;wherein the first bottom end panel is foldably connected to the bottom panel along a ninth longitudinal fold line; andwherein the second bottom end panel is foldably connected to the bottom panel along a tenth longitudinal fold line. 4. The method of claim 3, further comprising: folding the at least one first side panel flap with respect to the first side panel about the fifth longitudinal fold line; andfolding the at least one third side panel flap with respect to the second side panel about the seventh longitudinal fold line. 5. The method of claim 4, wherein: the at least one first side panel flap comprises a pair of first side panel flap portions connected to one another at a fifth oblique fold line;the at least one third side panel flap comprises a pair of third side panel flap portions connected to one another at a sixth oblique fold line;the folding of the at least one first side panel flap with respect to the first side panel about the fifth longitudinal fold line comprises folding one of the pair of first side panel flap portions about the fifth oblique fold line; andthe folding of the at least one third side panel flap with respect to the second side panel about the seventh longitudinal fold line comprises folding one of the pair of third side panel flap portions about the sixth oblique fold line. 6. The method of claim 5, further comprising: at least partially closing a second end of the tubular structure. 7. The method of claim 2, wherein, after the folding of the at least one first top flap and the at least third top flap with respect to the top panel about the first longitudinal fold line and the third longitudinal fold line, respectively, the method further comprises: loading the tubular structure with a plurality of containers. 8. A method of erecting a carton, the method comprising: obtaining a blank comprising a plurality of panels comprising a bottom panel, a first side panel foldably connected to the bottom panel, a second side panel foldably connected to the bottom panel, a first top panel foldably connected to the first side panel, and a second top panel foldably connected to the second side panel;a plurality of top flaps comprising a first top flap foldably connected to the first top panel at a first longitudinal fold line and a second top flap foldably connected to the second top panel at a second longitudinal fold line, the first top flap comprising a pair of first top flap portions connected to one another at a first oblique fold line the second top flap comprising a pair of second top flap portions connected to one another at a second oblique fold line; anda bottom end panel foldably connected to an end of the bottom panel;folding the first top flap at the first oblique fold line, and folding the second top flap at the second oblique fold line;forming a top panel by at least partially overlapping the first top panel and the second top panel, and forming a top end flap by at least partially overlapping the first top flap and the second top flap;folding the plurality of panels to form a tubular structure; andat least partially closing a first end of the tubular structure by folding the top end flap about the first longitudinal fold line and the second longitudinal fold line, folding the bottom end panel to overlap at least an inner portion of the top end flap, and folding at least an outer portion of the top end flap to overlap the bottom end panel. 9.
