  • Compressed gas aerosol spray system with a dip tube vapor tap hole
    Patent number: 5143288
    Abstract: Apparatus and method for using a compressed gas in an aerosol spray system to produce and maintain an effective aerosol spray includes the use of an aerosol spray valve 4 for emitting the aerosol spray. A dip tube 18 is coupled to the valve 4 and extends into the spray system. The tube 18 has an upper portion which is substantially airtight above an initial liquid level 14. A lower portion of the dip tube 18 extends below the initial liquid level 14 and has a liquid entrance hole 24 substantially at the bottom thereof. A vapor tap hole 26 is provided in the dip tube 18 above the liquid entrance hole 24 and below the initial liquid level 14. The vapor tap hole 26 allows compressed gas 16 to enter the tube 18 and mix with the liquid 20 therein when the liquid level 28 has fallen below the vapor tap hole.
