A molded cover/seat secures over an opening in a carrying box on a two-wheeled cart to serve as a cover and a seat. The cover/seat has a smooth top for sitting and a ribbed waffle pattern bottom for strength. An encircling flange with interior corner protrusions securely engages the top of the carrying box. Semicircular recesses in one edge accommodate the two rods of the handle. Bottom protrusions engage a hand hole on one side of the carrying box to secure the cover/seat to the side of the carrying box for storage and transport.

What is claimed is: 1. A combination cover and seat for a carrying box having a top opening and a front side hand hole, the combination cover and seat comprising: a rigid planar surface smooth and flat on top conforming in shape to a top opening in a carrying box having a top opening and a front side hand hole to admit a hand of a user for lifting the carrying box, the rigid planar surface fitting securely thereon in a first position over the top opening to serve as a cover and a seat on top of the carrying box, the rigid planar surface having at least two protrusions on a bottom surfaces, the protrusions configured to engage the hand hole on the front side of the carrying box with a tight friction fit to enable the rigid planar surface to be secured to the front side of the carrying box with the protrusions engaging the hand hole on the front side of the carrying box with a tight friction fit in a second position for securing the rigid planar surface to the front side of the carrying box for storage and transporting. 2. The combination cover and seat of claim 1 wherein the carrying box is mounted on a two-wheeled cart having a long handle and the rigid planar surface has at least one recess on an edge of the planar surface to accommodate the handle therein with the cover/seat installed over the top opening of the carrying box. 3. The combination cover and seat of claim 1 wherein the rigid planar surface further comprises an encircling flange which extends around the top opening of the carrying box and the flange has corner protrusions which engage the exterior surfaces of the carrying box at the corners to secure the rigid planar surface over the carrying box opening. 4. The combination cover and seat of claim 1 wherein the rigid planar surface is formed of molded plastic with a ribbed waffle pattern on a bottom surface for sufficient strength to enable a person to sit on the rigid planar surface. 5. In combination a folding carrying box and a combination cover and seat for the folding carrying box, the combination comprising: a carrying box comprising a bottom, a back side mounted on a two-wheeled hand truck having a pair of back wheels and a long extensible and retractable handle, a front side having a hand hole therein to admit a hand of a user for lifting the carrying box, a pair of opposing side panels between the front side and the back side, the side panels each structured to fold in along a hinged vertical fold line in each of the side panels to collapse the carrying box to fold flat for storage, and a top opening in the carrying box; a rigid planar surface smooth and flat on top conforming in shape to the top opening in the carrying box, the rigid planar surface fitting securely thereon in a first position over the top opening to serve as a cover and a seat on top of the carrying box with the carrying box in a stationary position with the front of the carrying box contacting the ground, the rigid planar surface having at least two protrusions on a bottom surface, the protrusions configured to engage the hand hole on the front side of the carrying box with a tight friction fit to enable the rigid planar surface to be secured to the front side of the carrying box with the protrusions engaging the hand hole on the front side of the carrying box with a tight friction fit in a second position for securing the rigid planar surface to the front side of the carrying box for storage and transporting so that the rigid planar surface can remain attached to the front side of the carrying box when it is folded flat.
