  • Patent number: 6820662
    Abstract: A machine that makes bubbles that are dispensed vertically. A membrane-forming system forms a bubble solution membrane over a bubble ring. Air is passed through the bubble ring by a blowing fan, which is intermittently operated to allow contact between a membrane-forming ring and the bubble ring. Bubble solution is continuously supplied to the bubble rings from a central reservoir. Safety switches prevent operation of the bubble-making machine unless there is bubble solution in the reservoir, the main housing is properly connected to the fan, and the bubble machine is in an upright position (and not tipped over). The present invention provides continuous operation for the duration of the bubble solution supply, and is easily washed, used, maintained, and manufactured.
