  • Patent number: 4631859
    Abstract: A grave marker and flower receptacle for use in a cemetary includes a base portion of granite or marble having a cylindrical opening. A molded flower receptacle is formed in the cylindrical opening from resin material such as epoxy or polyester which permanently bonds to the base and which overlayes the upper surface of the base in a decorative construction. A method of forming an integral grave marker and flower receptacle is also disclosed whereby a mold insert is positioned in the cylindrical opening in the base. The flower receptacle material is poured into the area between the insert and the opening in the base and a negative impression of the insert is made as the receptacle material hardens to form the flower receptacle. In an alternative embodiment, the molded flower receptacle is formed in combination with a first base section, after which the first section is cemented to the remaining section of the base.
