Patent attributes
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.
