<p>A new carton blank (10) configuration and a method of folding it to provide a liquid-tight, non-wicking carton or container bottom (80). The scoring pattern and bottom panel configuration of the carton make possible the formation of a carton bottom (80) having no exposed edges of the carton blank on the inside of the container without folding or slitting any bottom panel (34, 36) prior to the carton folding and sealing process. The carton blank (10) is shaped and scored for folding and is substantially a flat container bottom (80). An extension tab (32) extending from one of the two bottom panels (34, 36) allows for a non-wicking surface to be formed and tucked into the interior of the carton bottom (80) during the bottom-forming process as the edges of the two bottom panels (34, 36) contact each other. The inside surface of the bottom panel not having an extension tab (36) contacts the extension tab (32), folding the extension tab (32) back along a score line (33). As the bottom panels (34, 36) move closer together, the bottom panel with the extension tab (34) is tucked under the other bottom panel (36), and the folded surface of the extension tab (32) covers the gap between the various bottom panels (34, 36, 38, 44) of the carton bottom (80), leaving no exposed edges on the interior of the carton.</p> |
