A file (10) includes a support member (12) having an abrasive surface (14) treated with a sanitizing agent. The surface (14) or the interstices (18) between particles (16) of abrasive hold the sanitizing agent which is released with use of the file (10). The sanitizing agent is either in a liquid carrier or contained within microcapsule (20). The microcapsule (20) are frangible and break upon use of the file to release the sanitizing agent. The file surface (14) may comprise granular abrasive particulate (16) having a size ranging from 40 to 1200 grit which provided the interstices (18) between at least some of the particulate (16). An aqueous coating having dispersed therein an adhesive and the microcapsules (20) is applied to the granular particulate (16). The coating is dried to deposit in the interstices the microcapsules (20). The adhesive binds the microcapsules (20) to the granular particulate (16). When a mixture of sanitizing agent and liquid carrier is used, the abrasive surface (14) is coated with the mixture and then the liquid carrier is removed to coat the surface (14) with the sanitizing agent.
L'invention porte sur une lime (10) comportant un support (12) dont la surface abrasive (14) est traitée par un désinfectant. La surface (14) ou les interstices (18) entre les particules abrasives (16) retiennent l'agent désinfectant qui se libère lors de l'utilisation de la lime (10). Ledit agent peut être un liquide porté par ou inclus dans des microcapsules fragiles (20) qui se rompent lors de l'utilisation de la lime et libèrent l'agent désinfectant. La surface (14) de la lime peut comporter des particules abrasives (16) d'une taille comprise entre 40 et 1200 grit, ce qui laisse des interstices (18) au moins entre certaines des particules (16). On applique sur les particules (16) un revêtement aqueux contenant un adhésif ainsi que les microcapsules (20). Le revêtement est séché de façon à déposer dans les interstices les microcapsules (20). L'adhésif fixe les microcapsules (20) aux particules (16). Lorsqu'on utilise un mélange d'agent désinfectant et de liquide porteur, la surface abrasive (14) se recouvre du mélange, puis le porteur s'élimine et la surface (14) se couvre de désinfectant.
