Disclosed is a straw assembly for compressed air, which is usable in an aerosol or spray injection pressure container. The compressed air has a high pressure of more than 5 kg/cm2 and is filled in the container along with solution. The straw assembly includes a solution straw, a pressure regulator to reduce the pressure of the solution to an appropriate value so as to allow the compressed air to be used as an injection propellant for discharging the solution to the outside, and a safety valve or vinyl bag to prevent the compressed air from being discharged to the outside when the container is inverted. The straw assembly provides an eco-friendly product substituting the compressed air for liquefied gas that is used as an injection propellant for a conventional packing pressure container and achieves an aerosol or spray injection straw product having a low price. |
