Patent number: 4667855Abstract: Valves connected to dip tubes in conventional pressurized "aerosol"-type containers for dispensing materials which react or cure upon dispensing (e.g. moisture-curable polyurethanes), are protected against premature failure by introducing a small amount of dry, inert gas into the dip-tube shortly after charging the container. The gas (e.g. nitrogen) acts as a barrier to prevent contact between the product in the container and the valve mechanism prior to use of the product. Preventing such contact avoids premature hardening of product in the valve mechanism caused by reaction of product with moisture.Type: GrantFiled: November 25, 1980Date of Patent: May 26, 1987Assignee: W.
