Abstract
A liquid dispenser for dispensing sterile liquid comprising a container for storing the sterile liquid, a nozzle assembly mounted on the container, and a filter which has at least one surface and a plurality of its pores coated with a metallic material, e.g., a metal or metal oxide or metal salt, that is bacteriostatic or bacteriocidal, is described. The metal coated filter, methods for coating the filter, and methods for using the liquid dispenser are also provided.
Claims18
A liquid dispenser for dispensing a sterile liquid, comprising:
- a container for storing the sterile liquid;
- a nozzle assembly mounted on said container, said nozzle assembly having a passageway for enabling flow of the sterile liquid therethrough from said container during liquid dispensing;
- and
- a filter having a downstream and an upstream surface and being attached to said nozzle assembly so that said filter extends across said passageway to direct liquid and air flow through said filter from said container to said downstream surface of said filter;
- said filter being at least partially coated on the downstream surface with a first bacteriostatic or bacteriocidal metallic material consisting essentially of silver, silver oxide, a silver salt, or mixtures thereof;
- said filter having pores with a pore size so as to preclude passage of microorganisms therethrough and so as to permit passage of the sterile liquid from said container therethrough;
- and
- said filter being at least partially coated within a plurality of said pores with said first metallic material.
A dispenser for dispensing sterile liquids, said dispenser having a filter attached to a container for said liquids, the improvement comprising:
- said filter being at least partially coated on a downstream surface thereof with a metallic material consisting essentially of a silver, a silver oxide, a silver salt, or mixtures thereof;
- said filter extending across a passageway provided by said container leading from said container to a dispensing area where said liquid is dispensed;
- said filter having pores with a pore size so as to preclude passage of microorganisms therethrough and so as to permit passage of the sterile liquid from said container therethrough;
- and
- said filter being at least partially coated within a plurality of said pores with said metallic material.
