Patent number: 7090916Abstract: The present invention provides a paper product for use in sterilizing an area. The paper product contains at least one paper sheet or pellet containing one or more dry chemical materials, one or more dry deliquescent materials, or mixtures thereof. The dry chemical materials are either inactive antimicrobial or biocidal chemical materials or are capable of reacting with another chemical material to produce one or more active antimicrobial or biocidal chemical materials. When the paper product is placed in an atmosphere containing water vapor, the deliquescent material(s) attracts water and dissolves, thereby either hydrating and rendering active the inactive antimicrobial or biocidal chemical material(s), or providing a medium in which the chemical materials will react to produce one or more active antimicrobial or biocidal chemical materials.Type: GrantFiled: June 7, 2002Date of Patent: August 15, 2006Assignee: CATHM, LLCInventors: James A. Aamodt, John W. Colvin
