  • Patent number: 4840332
    Abstract: Disclosed is a golf ball holder comprising a generally cylindrical wall element forming a tubular member. There is an elongated aperture running along the entire length of the tubular member between opposed open ends in the tubular member. The tubular member is of a uniform diameter with the opposed open ends having a diameter slightly less than the diameter of the golf balls. The tubular member is made of a resilient material to enable the wall element to expand outwardly when a golf ball is inserted into either of the open ends. The aperture is sufficiently wide to allow the finger of the user to be inserted into it to force a golf ball out of either end but not so wide as to allow a golf ball to be inserted into the tubular member through the aperture. There is a stop member at one of the open ends which prevents a ball from passing through this end unless the user applies pressure to the golf ball and forces it past the stop member.
