| abstract |
An aerosol fluid dispenser comprises a container for a liquid, a dispenser head fitted to the container and having a fluid outlet, a dip tube formed from a length of hollow membrane, the hollow membrane having an open end which is coupled to the dispenser head so as to be able to communicate with the fluid outlet, and having a closed end that sits within the container, a liquid disinfectant, and a propellant. The hollow membrane is adapted to pass liquid in preference to gas so that when the dispenser head is actuated liquid disinfectant travels from the liquid container through the wall of the dip tube to the fluid outlet under a pressure differential established across the wall of the membrane. A preferred disinfectant composition comprises a biocidal agent, a chelating agent and a surfactant, such a composition being suitable for disinfecting a fomite contaminated with a virus. |
