  • Patent number: 5876489
    Abstract: A germ-removing filter includes a filter substrate, and an antimicrobial material dispersedly mixed into the filter substrate. The antimicrobial material is antimicrobial fiber bonded with silver ion. The total amount of the silver ions present in the filter substrate material when mixed with the antimicrobial fiber is equivalent to an amount of silver ions contained in an antimicrobial fiber which is mixed at more than 10 wt % in the filter substrate and which has entire exchange groups or bonding groups thereof exchanged or bonded with silver ions. An apparatus using the filter for maintaining a sterile room under sterile condition is also disclosed.

  • Patent number: 5531908
    Abstract: A germ-free liquid dispenser is disclosed. The dispenser includes a liquid container having a liquid outlet opening, a reservoir for receiving and reserving the liquid from the container, a holder for detachably holding the liquid container at its supply posture for orienting its outlet opening downward to allow the liquid within the container to flow down through the opening into the reservoir, a dispenser device for dispensing the liquid from the reservoir by allowing the liquid to flow down from the reservoir, and an antibacterial element having an antibacterial surface capable of killing germ through a physical contact therewith. The antibacterial element is disposed inside the reservoir in such a manner as to contact the liquid inside the reservoir while allowing the reservoir to dispense the liquid therefrom.

  • Patent number: 5366619
    Abstract: A germfree drinking water dispenser includes a reservoir for receiving and reserving drinking water such as mineral water and an ozone injecting device. The ozone injecting device includes a compact ozone generator and an injection opening which is opened into the reservoir. Ozone generated by the ozone generator is injected, by e.g. a blower, through the injection opening into the drinking water at the reservoir. The ozone injecting device is activated only for a short necessary period of time when the dispenser is out of service. So that, after the drinking water in the reservoir is fully sterilized, a sufficient period of time is allowed to lapse for any ozone remaining in the water to dissolve until the next first use of the dispenser.
