Inflatable noisemaker

Abstract

An inflatable noisemaker has a flexible envelope and a multiplicity of pellets contained within the envelope. The pellets can be made of wood, glass, plastic, metal, dry beans or dry peas and are free to bounce around in response to an impact on the envelope and the envelope is constructed to be grasped manually and to enclose a gas under pressure.

What is claimed is:  
     
         1 . An inflatable noisemaker comprising: 
 a flexible envelope and    a multiplicity of pellets contained within the envelope, wherein:    the pellets are free to rebound and reverberate in response to an impact on the envelope, and    the envelope is constructed to be grasped manually and to enclose a gas under pressure.    
     
     
         2 . An inflatable noisemaker according to  claim 1  wherein the envelope is formed of a material comprising a polymer.  
     
     
         3 . An inflatable noisemaker according to  claim 1  wherein the envelope is formed of a material comprising a polyamide.  
     
     
         4 . An inflatable noisemaker according to  claim 1  wherein the envelope is formed of a material comprising Mylar®.  
     
     
         5 . An inflatable noisemaker according to  claim 1  wherein the pellets are rounded.  
     
     
         6 . An inflatable noisemaker according to  claim 1  wherein the pellets are spherical.  
     
     
         7 . An inflatable noisemaker according to  claim 1  wherein the pellets are rigid.  
     
     
         8 . An inflatable noisemaker according to  claim 1  wherein the decibel level can be calibrated by merely changing the number and/or type and/or size of pellets in the same air envelope/chamber.  
     
     
         9 . A noisemaker according to  claim 1  wherein the pellets have a specific gravity greater than 1.0.  
     
     
         10 . A noisemaker according to  claim 1  wherein the pellets have a specific gravity within the range of 2.0 to 3.0.  
     
     
         11 . A noisemaker according to  claim 1  wherein the pellets have a specific gravity of substantially 2.25.  
     
     
         12 . A noisemaker according to  claim 1  wherein the pellets are made of a material selected from the group consisting of metal, glass, plastic, dry beans and dry peas.  
     
     
         13 . A method of calibrating the decibel level of an inflatable noisemaker comprising the steps of: 
 providing a flexible envelope;    providing a multiplicity of pellets contained within the envelope;    freeing the pellets to rebound and reverberate in response to an impact on the envelope;    constructing the envelope to be grasped manually and to enclose a gas under pressure; and    changing the number of pellets to control the maximum noise level.
