ABSTRACT:

FIELD OF THE INVENTION
The present invention related to inflatable devices.
BACKGROUND OF THE INVENTION
Many noisemakers work by rapidly forcing air through a mechanism to produce a sound. Inflatable noise-makers have a container which is filled with air and then the air is forced out of the container through a single outlet producing a sound. Once the noise-maker is used to produce a sound, it must be refilled with air in order to produce sound again.
Therefore, there is a need in the art for a noise-maker that refills with air after each use without directed effort from the user. The present invention satisfies this and other needs.
SUMMARY OF THE INVENTION
The present invention is a self-inflating, noise-maker. In accordance with a currently preferred exemplary embodiment, a noisemaker includes an enclosed membrane having an inlet and an outlet that is filled with porous material. The noise-maker is in an inflated state when the porous material is saturated with air and a compressed state when the air is forced out of the porous material. When pressure is applied to the noise-maker, the air inside the membrane is forced through the outlet and the noisemaker reaches the compressed state. When the pressure is released, the noise-maker changes from the compressed state to the inflated state as air flows through the inlet.
