DIP TUBE VAPOR TAP COMPRESSED GAS AEROSOL SYSTEM

摘要

An 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) and a dip tube (18) coupled thereto. The tube (18) has an upper airtight portion above an initial liquid level (14). At the bottom of the tube (18) is a liquid entrance hole (24). A vapor tap hole (26) is provided in the tube (18) above the liquid entrance hole (24) and below the initial liquid level (14). The vapor tape 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. Even after the pressure has fallen, the mixing of the compressed gas (16) with the liquid (20) in the dip tube (18) substantially reestablishes the deteriorated spray characteristics to produce an effective spray.
