  • Patent number: 8636557
    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.
