Abstract
A self-inflatable balloon has a communication discernible on its surface and has its mouth opening pneumatically sealed to a funnel through which air is selectively directed upon actuation of a triggering event. Audible communication may also be actuated by the same or a different triggering event. A method of communicating comprises a message which becomes cognizable upon inflation of a message carrying device.
Claims5
In combination, an assembly comprising:
- (a) an inflatable balloon having an interior with an opening capable of being inflated by an introduction of gas;
- (b) means for providing pressurized gas adapted to be assembled in pneumatic relation to the opening of said balloon to inflate said balloon upon actuation of switch means, said pressurized gas providing means comprising a turbine in an air flow channel pneumatically connected to the opening of said balloon, and in which channel said turbine compresses gas when rotated;
- and
- (c) switch means selectively actuable into an opened positioned and into a closed position and pneumatically connected to said inflatable balloon and to said means for providing pressurized gas, said switch means for opening an air conduit between said pressurized gas means and said balloon when in an opened position, and for sealing said conduit when in a closed position.
