Abstract
Articles and a method related to use of a biocide (e.g., triclosan) incorporated into communication and data transfer/entry products in order to provide cleaner, fresher and more hygienic surfaces by controlling a broad range of gram-positive and gram-negative bacteria, yeast, and fungi on the surfaces of such products.
Claims15
A germ-resistant article for information communication or manipulation comprising:
- a device for information communication or manipulation selected from the group consisting essentially of cellular and digital phones, digital pagers, personal digital assistant (PDA) devices, personal computer keyboards, personal computer mice, watches having information communication or manipulation function, dictation devices, portable note-taking devices, remote controls, security system key pads and remote controls, credit, check and debit cards having information-storage components, information-storage cards, smart cards, electronic signature cards, audiovisual keypads and buttons, musical keyboards, bar code readers, calculators, fax machines, electronic lock key pads, office and public telephones, electronic game keyboards and buttons, cash register keypads, copy machine keypads, gambling machine handles and buttons, automated teller machine keypads, elevator controls, and gas pump controls, utilizing the electromagnetic energy spectrum, and having a surface comprising a polymeric material;
- and
- at least one antimicrobial agent selected from the group consisting essentially of chlorinated phenoxy and poly-hexamethylene biguanide hydrochloride incorporated within the surface, wherein the antimicrobial agent exhibits controlled migration through the polymeric material of the surface when an imbalance of vapor pressure of the antimicrobial agent demands equalization, thereby continuously inhibiting microbial growth and promoting asepsis on the surface.
A method of manufacturing a germ-resistant article for information communication or manipulation having at least one surface having antimicrobial characteristics that inhibit microbial growth and promote asepsis on the surface, comprising:
- making an admixture of polymeric material and an antimicrobial agent selected from the group consisting of chlorinated phenoxy and poly-hexamethylene biguanide hydrochloride,
- forming a surface for a device for information communication or manipulation by molding said admixture of polymeric material and antimicrobial agent, wherein in the surface, the antimicrobial agent exhibits controlled migration through the polymeric material of the surface when an imbalance of vapor pressure of the antimicrobial agent demands equalization to thereby continuously inhibit microbial growth and promote asepsis on the surface.
The method of clam 5, wherein the polymeric material of the surface is polyethylene.
A method of manufacturing a device for information communication or manipulation possessing at least one surface possessing antimicrobial characteristics that inhibit microbial growth and promote asepsis on the surface, which comprises:
- providing a surface of a polymeric material for a device for information communication or manipulation;
- associating an antimicrobial agent, selected from the group consisting of chlorinated phenoxy and poly-hexamethylene, with said surface by applying said antimicrobial agent as a topical applicant to said surface;
- thereby forming a polymeric surface containing the antimicrobial agent, wherein in the surface the antimicrobial agent exhibits controlled migration through the polymeric material of the surface when an imbalance of vapor pressure of the antimicrobial agent demands equalization, to thereby continuously inhibit microbial growth and promote asepsis on the surface.
