Claim:
A cooler, comprising: a. a box portion having a rigid outer shell and a rigid inner shell, an insulative material disposed between the outer shell and the inner shell, the inner shell defining a chamber therein having a floor and opening to a inner shell top, the floor sloping from a higher end to a lower end, the box portion defining a drain hole passing therethrough adjacent to the lower end, the inner shell and the outer shell defining a cavity therebetween adjacent to the floor, the inner shell forming a first upright wall of the cavity, a second upright wall of the cavity and a horizontal wall of the cavity, the cavity opening to a hole defined by the outer shell, the outer shell including a bottom from which four feet molded into the outer shell extend so as to form an air gap between the bottom and any surface upon which the cooler is placed; b. a removable tray that fits into the cavity; c. a door configured to selectively cover the hole defined by the outer shell, the door hingedly attached to the outer shell with an attachment member; d. the outer shell defining a first recess about the hole so that neither the door nor the attachment member extends beyond an outer surface of the outer shell when the door is in a closed position; e. a lid portion configured to fit against the inner shell top; f. a hinge including a first hinge part molded into the outer shell adjacent the inner shell top and second hinge part molded into the lid portion, the first hinge part coupled to the second hinge part to allow hinged movement therebetween; g. a seal configured to seal the lid portion to the box portion, the seal including: i. a flat upper peripheral edge defined by a top of the box portion; ii. a flat lower peripheral edge defined by a bottom of the lid portion and configured to matingly engage the flat upper peripheral edge defined by the box portion; iii. a protrusion extending upwardly substantially along the entire upper peripheral edge of the box portion; and iv. an indentation extending upwardly into substantially the entire lower peripheral edge of the lid portion and configured to matingly engage the protrusion; h. a locking device configured to hold the lid portion against the box portion, the outer shell and the lid portion defining a second recess into which the locking device fits so that the locking device does not extend beyond the outer shell when the locking device is in a closed state; i. the outer shell having two opposite sides, wherein each opposite side defines a rigid gripping surface recess to facilitate lifting of the cooler, an elongated handle also extending from each opposite side to facilitate carrying of the cooler by two people; and j. a drain spout extending from the drain hole to facilitate draining of liquids from the cooler, the outer shell defining a recessed area adjacent to the drain spout and the drain spout having a length so as not to extend beyond the recessed area.
