  • Patent number: 6241571
    Abstract: A bubble blowing assembly used to blow bubbles made of soap film. The bubble blowing assembly includes a housing. In the housing is formed an air flow chamber having a first end and a second end. A one-way valve is disposed at the first end of the air flow chamber. The one-way valve connects to a balloon or another inflatable air vessel. An arm is pivotally connected to the housing and is selectively positionable between a first position and a second position. The arm defines an aperture. When the arm is in the first position, the aperture on the arm is positioned in said reservoir. When the arm is positioned in the second position, the aperture on the arm is positioned next to the second end of the air flow chamber. An activation mechanism is provided within the housing. The activation mechanism engages both the one-way valve and the arm. When the activation mechanism is in an operating position, the activation mechanism moves both the one-way valve to its open condition and the arm to its second position.
