An improved water bottle design for use with a water cooler type bottled water dispensing apparatus is provided in which the water bottle includes a horizontal surface area positioned around the base of the neck of the bottle, where the bottle contacts an annular opening of the housing above an open end of a reservoir portion of the housing of the bottled water dispensing apparatus. This flat horizontal surface area results in greater stability for the water bottle on the housing than can be achieved with conventional bottles which engage the annular opening of the housing at a vertically curved surface of the bottle. Moreover, no special adapters or couplings are necessary to produce an interfit between the water bottle and the housing, and therefore, the improved stability is achieved in a very simple manner. In second and third embodiments, the water bottle further includes a transition region that is substantially perpendicular to the horizontal surface area and may contact with an interior periphery of the bottle-receiving opening of the housing. By contacting with the interior periphery, the transition region further provides for a tighter fitting of the water bottle to the housing, so that the inverted bottle seats with greater stability on the housing without increasing the complexity of the overall structure as the case for the use of special adapters or couplings.
