Abstract: The top of a ring-like film forming member with an opening receives bubble solution and gravity causes the solution to flow over the protruding surface of a movable member within the opening such that the surface tension of the bubble solution causes a film to form within the opening and over the surface. The movable member is moved out of the way to allow wind from a wind supply to reach the rear of the ring-like member to form and release a bubble. The protruding shape of the surface allows the film to form and in intact as the member is moved. A trigger mechanically connected to the movable member controls the position of the movable member and the energization of the motor which drives the bubble solution supply and the wind supply. Continuous depression of the trigger causes a series of bubbles to be formed and released.

Abstract: A hand-held bubble generating apparatus designed to mimic the appearance of a gun or a cannon. A housing may be coupled with a non-spill reservoir, and bubble generating liquid may be stored in the non-spill reservoir. A tube may communicate the bubble generating liquid from the reservoir to a bubble assembly support inside the housing. The bubble assembly support may hold a rotational bubble ring comprising a plurality of individual rings spaced about the outer circumference. When rotated proximate to and across a liquid dispensing section, each individual ring may receive enough bubble generating liquid to form a film across each ring. By rationing the amount of bubble liquid released on each individual ring, the device can incorporate a closed, non-spill reservoir. When air is generated and blown through the film of bubble generating liquid on each of the individual rings of the rotational bubble ring, bubbles are produced.
