Composite plant holders and method of making them
Abstract
Abstract The present invention is directed to a composite plant holder and a method of making a composite plant holder. Specifically, the method comprises forming the external vertical shape of a desired plant holder by shaping metal sheet and permanently attaching opposite ends of the metal sheet to one another. This metal sheet is then placed on a flat non-adhering surface in its upright or vertical position. Next, a gel coat is applied to the walls of the metal sheet and to the open bottom. Subsequently, a mixture of resin and fiber to form fiberglass is applied on the inside wall as well as on the bottom. This results in the formation of a receptacle which has the metal sheet for outside vertical surfaces and has layers of gel coat and fiberglass for inside walls and a base. Any resin and fiber which extends beyond the top of the sheet metal is cut either while the resin and fiber have not yet hardened or after they have hardened. In a preferred embodiment, the plant holder is cylindrical in configuration, employs a lock seam for joining the ends of the sheet metal to one another and includes 180° lips and its top and bottom.
