  • Patent number: 5031253
    Abstract: A method of making a sanitary toilet anti-splash and silencer device and an article produced thereby. A floatable member is formed from two or more layers or sheets of biodegradable paper. The layers are joined together by an adhesive pattern which establishes individual compartments between the layers. A gas forming agent is placed in at least a plurality of the compartments. The gas forming agent releases a gas such as CO.sub.2 when exposed to water thereby providing buoyancy when the device is placed on the water in a toilet. The device may have a target indicia imprinted thereon and it may be provided with a paper strip or string so that the device may be positioned or held in place in the toilet.
