  • Patent number: 8166702
    Abstract: The tree stand apparatus provides lateral support and a large reservoir created by the conical shape enables fewer fillings of the apparatus. The numerous transfer orifices ensure that clogging especially typical of evergreen tree stands, does not occur, as full communication exists between the tree cylinder and the reservoir. The ability to easily drain and refill the apparatus ensures fresh water supply as well as supply of nutrients that further enhance tree livelihood. Problems of water drainage typical of after-use of a tree stand are negated by the valved drain bib that is disposed immediately adjacent to the bottom of the reservoir, thereby ensuring full drainage. The apparatus provides fill holes that are diametrically opposed, with one fill hole radialy aligned with a float that slides vertically on a float slide to enable exterior viewing of internal water level.
