  • Patent number: 4154378
    Abstract: A metering arrangement for dispensing a predetermined quantity of product each time the dispensing valve of a pressurized container is operated. A flexible wall feed tube within the container is connected to the valve inlet, the tube having a restriction therein. Operating the dispensing valve reduces pressure in the tube, because of the restriction, to dispense the quantity of product, and to cause the tube wall to collapse and create a seal. When the valve is released, the pressure on the inside and outside of the tube equalizes by flow through the restriction.
