Buoyant dispensing device

摘要

A buoyant dispensing device for dispensing a material into a body of water. An inner receptacle contains the material and has apertures to permit the material to escape therefrom. A housing having an outer receptacle houses the inner receptacle therein and has corresponding apertures. The inner and outer receptacles are rotatable and fixable with respect to one another to enable a varying degree of overlap between the apertures to control the amount of material dispensed therethrough. Vanes circumscribe the receptacles and corresponding spokes and guard rings interconnect the receptacles and the vanes and keep the receptacles spaced a predetermined distance from other objects. The vanes absorb an impulse force from the body of water and impart the impulse force to the receptacles in the form of a rotational reaction force whereby the dispensing device rotationally and linearly displaces itself within the body of water.
