  • Patent number: 6053368
    Abstract: A dispensing apparatus for fluids from a storage vessel in which air flows into the storage vessel (1) while the fluid is being dispensed to compensate pressure. In this dispensing apparatus is provided, filters for sterilizing, degerminating or reducing germs are provided in the air intake area and, separately from this, filters for sterilizing, degerminating or reducing germs in the fluid are provided in at least one part of the fluid outlet. This means that a dispensing apparatus can be provided which can be adapted to available conventional storage vessels and filling systems, and which efficiently protects the fluid in the storage vessel from becoming contaminated at reasonable costs so that the use of preservatives is rendered unnecessary. This dispensing apparatus can be a pump (2) or it can be formed such that the storage vessel is a squeezy bottle (31).

  • Patent number: 5232687
    Abstract: A fluid dispenser incorporating an oligodynamically germicidally active substance for maintaining the dispensation of germ-free fluid, particularly eye drops. The delivery passage from a supply container associated with the fluid dispenser of the invention contains an oligodynamically germicidally active substance that is soluble in the fluid to be dispensed. The device does not require air pressure within the container, thus eliminating one avenue for the introduction of germs into the fluid. The device includes a metering pump and inlet and outlet valves. The above-mentioned fluid soluble oligodynamically germicidally active substance is situated in the region of the inlet valve or the inlet thereto and/or the outlet therefrom.
