Abstract: A table with a molded plastic body and a molded plastic plug fitted in a large round bottom opening in the body. A sealed internal body volume accommodates ballast. An internal hollow sleeve extends from an opening in the top of the body two a hollow core in the plug. An upper and lower corrugated gripping elements in the hollow sleeve and in the hollow core of the plug grip the pole of an umbrella. The round plug retained in the large round bottom opening by spin welding the round plug within the large round bottom opening.

Abstract: A pallet is taught having two openings on at least one side of the pallet, the two openings formed by a bisecting wall separating the openings. More specifically, at least one bisecting post creates a first opening and a second opening Each of the said first and second openings each have a convexly curved runner, said runner convexly curved along its width; and a concavely curved ceiling, said ceiling concavely curved along its width wherein the center point of the radius of the curved runner varies from the radius of the curved ceiling.

Abstract: An asymmetric mold core for forming curved floor openings in pallets is taught.

Abstract: An asymmetric mold core and method for use for forming curved floor openings in pallets is taught. The mold core contains: a base, the base attachable to a frame in a rotomold, a bottom section integral at a distal end to the base, and a top section integral at a distal end to the base. Both the top section and the bottom section have convex radial curve shape, but the top section curve and the bottom section curve are positioned by having different centers of rotation so when the core is actuated it is only actuated around the center of rotation about the bottom curve which causes the top cure to drop away from the upper molded surface.
