Claim:
A dispenser comprising a container defining a reservoir for holding a plurality of balls, a container mouth for releasing balls from the container, a flow path extending from the reservoir to the container mouth, a first ball flow regulator disposed in said path, a second ball flow regulator disposed in said path in series with said first ball flow regulator, each of said first and second ball flow regulators being capable of blocking flow of balls along the path, and means for simultaneously operating said first and second regulators, said regulators being designed so that one, but not both, of the regulators blocks ball flow at any time, wherein the operating means comprises at least one button which is depressed to operate the regulators wherein the first regulator comprises a first pair of elements which normally permit ball flow, but move closer together, to block ball flow, when the button is depressed, wherein each element of said first pair is a weir, and wherein each weir has a pair of flats which act as stops when the flats engage flats on the other weir.
