  • 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: 5692649
    Abstract: A suction and force pump for a fluid in a sealed fluid container makes possible the drawing off by suction of residual air after the filling of the container with fluid, with the piston (3) in a particular position in the pressure cylinder (8) of the pump, by means of the pump channel (7) of the pump itself. For this purpose there is provided a channel for drawing off the residual air by suction, from the upper side of the fluid container through openings (13), a gap between piston (3) and the internal wall of the pressure cylinder (8), which gap is sealed with respect to the pressure cylinder (8) only by means of a peripheral sealing lip (9), through the pressure chamber (6) to the pump channel (7). The valve (5) to the fluid container is thereby closeable independently of pressure during the pumping away, by means of a plunger (11).
