发明名称 Bubble blowing wand
摘要 A bubble blowing wand for use with a bubble blowing liquid comprising two substantially concentric rings for providing a bubble or bubbles formed within a bubble. The concentric rings are substantially in the same planar relationship with respect to each other. The rings can be substituted with any closed geometric form so long as the peripheries are implaced within each other in a substantially spaced concentric relationship. The preferred concentric rings are formed as a larger outside ring and a smaller inner ring. The larger outside ring is attached to a handle at its outer edge, while the inner surface thereof supports a stem to which the inner ring is connected. Both of the rings have relieved or cut surfaces providing a larger surface area on the rings to accommodate greater amounts of bubble blowing liquid. Attendant with the use of the bubble blowing wand is a substantially spill-proof container having an elastomeric top with at least one slit therein that can be widened when an object passes therethrough, or through shaking of the contents. After deformation, it has sufficient elasticity and memory to return it to the general slit configuration, thereby preventing substantial spills but not forming a completely drip-free and liquid obstructing passage.
