Abstract
An article carrier which permits ice to be added to the carrier after removing the top to cool the contents. The carrier is formed from a paperboard blank having a waterproof interior surface. The end and side panels are connected by gusset panels, the end portions of which are adapted to be in nonadhered face-to-face relationship. When the top panel of the carrier is removed, these portions of the gusset panels are relaxed, allowing the side and end panels to pivot out about their foldable connection to the bottom panel for a limited distance to expand the interior of the carrier while maintaining the carrier in watertight condition.
Claims7
An article carrier having a watertight interior, comprising;
- top and bottom panels having side edges and end edges;
- side panels connected to the side edges of the top and bottom panels;
- end panels connected to the end edges of the top and bottom panels;
- a gusset panel connecting adjacent ends of adjacent side and end panels;
- a primary fold line in each gusset panel and a secondary fold line between the primary fold line and the adjacent ends of adjacent side and end panels;
- the gusset panels being inwardly folded about the primary fold lines, the portion of each gusset panel between the primary and secondary fold lines being adhered in face-to-face contact and the portions of each gusset panel between the secondary fold lines and the ends of the gusset panel being in nonadhered, substantially face-to-face contact, whereby outward movement of the side and end panels permits the nonadhered portions of the gusset panels to move away from each other, thereby permitting limited outward movement of the side and end panels upon opening of the top panel.
