Abstract
A tree stand for supporting a tree includes a base. The base includes a receptacle for receiving and supporting the trunk of the tree. A fluid reservoir for storing a fluid is detachably connected to the base. A first valve is attached to the reservoir and is operable between and open and closed position to allow fluid to flow outwardly of the reservoir in the open position and to prevent fluid from flowing outwardly of the reservoir in the closed position. A second valve is attached to the base and is in fluid communication with the receptacle. The second valve is operable in an open position to allow fluid to flow into the receptacle, and a closed position to prevent fluid from flowing outwardly of the receptacle. The first and second valves are disposed such that when the fluid reservoir is attached to the base, the first valve engages the second valve to cause the first valve to move from the closed position to the open position and allow the second valve to move from the closed position to the open position thereby allowing fluid to flow from the fluid reservoir into the receptacle.
