Abstract
A toy bubble-in-bubble assembly includes first and second hollow tubes, first and second rings, first and second connecting members, and a handle. First ends of the first and second tubes are located on a top portion of the handle. The first tube has a fluted second end which is connected to and separated from a bottom surface of the first ring by the first connecting member. The second connecting member connects the second ring to the handle. The rings are positioned such that planes across each of openings in the rings are essentially perpendicular to each other. The area of the opening in the first ring is smaller than the area of the opening in the second ring. A second end of the second tube is positioned adjacent a top surface of the first ring.

7326099 - Toy bubble-in-bubble generating assembly

A toy bubble-in-bubble assembly includes first and second coupled together bubble generators and first and second air supply conduits. The first gas supply conduit is positioned relative to the first bubble generator such that gas passing through the first air supply conduit impinges on the first bubble generator. The second gas supply conduit is positioned relative to the second bubble generator such that gas passing through the second gas supply conduit impinges on the second bubble generator. The openings in the first and second bubble generators are adjacent and positioned relative to each other such that a bubble generated at the opening in the first bubble generator is adjacent to an opening in the second bubble generator and thus enables the generated bubble to be blown into an opening in the second bubble generator to generate a bubble within a bubble.
