A quick erecting, disposable cooler which is transformable from a flat blank of corrugated sheet material may be non-destructively âknocked downâ or collapsed after being semi-erected. The deployed cooler is moisture-proof and lacks leak paths, so it reliably stores and transports melting ice and beverage containers. A generally rectangular center panel is integrally bordered by pairs of end panels and side panels. Each side panel supports a foldable top panel with special knockouts and tabs to facilitate subsequent coupling of the panels. Each end panel has a small flap at its outer edge facilitating coupling. Four, integral, diametrically spaced-apart corner panels interconnect the center panel with the end and side panels. Score lines defined between the orthogonally arranged panels facilitate folding. Corner panels include diagonal score lines.

Abstract:
A rugged, hand-held container for storing beverage containers is formed by folding together multiple panels defined in a pre-scored, slot-less blank. Each blank comprises a rectangular center panel integrally bordered by a pair of end panels and side panels. Integral, diametrically spaced apart corner panels interconnect the center panel with the other panels. Score lines between the adjacent panels facilitate folding. The center panel forms a cooler bottom, and blank end and side panels respectively form carton ends and sides. Each end panel has an outer locking panel comprising an elongated receptive slot. Each side panel has an integral outer handle panel comprising an inner roof segment that forms the container top and handle segments with locking tabs that are captivated within the receptive slot. A radiused locking tab ramp comprises an enlarged portion providing an overcenter action. Notches adjacent the tabs captivate the locking panels.
Folded Corrugated Container With Reinforced Quick-Locking Handles
A container comprises a knockdown carton made from a flat blank of corrugated material, and a knockdown lid. The carton comprises a center panel, foldable end panels, foldable side panels, and foldable corner panels. A pair of diametrically opposed corner panels are folded inwardly into contact with opposed end panels. The end panels comprise rectangular cutout holes surrounding foldable flaps. The lid has a central panel that is divided from integral end panels and integral side panels. A lid side panel extending vertically downwardly is coupled to the carton. Lid end panels have elliptical orifices that register with carton cutout regions and adjoining slots that align with handle anchor orifices. An alternative lid has flaps comprising major and minor segments separated by a diagonal fold line. The minor segment has an apex that releasably biases the flap in engagement with the end panel, yieldably locking the lid.
Foldable, Leakproof Multi-Mode Carton Construction
A slotless, leakproof storage carton ideally adapted for storing medical waste and a unique blank which can be quickly folded to form the carton. Corrugated sheet stock is coated with a plastic liner and cut into blanks, which are thereafter scored. Each blank comprises a center panel, a pair of bordering width panels, a pair of bordering length panels, and four corner panels. The scoring lines comprises a first pair of spaced apart, parallel fold lines extending longitudinally, and a second pair of parallel fold lines crossing the width of the blank. Diagonal fold lines are scored into the corner panels. The center panel forms a bottom of the carton, and the width and length panels respectively form carton ends and sides. The corner panels foldably divided into separate segments which abut each other and overly the length panels. A knock down system, which permits erected cartons to be flattened, includes a knock down line which evenly bisects the blank and a cooperating pair of groups of generally triangular relief lines formed in the center panel.
