A pneumatic dispenser for dispensing viscous material, for example, mastic caulk, from a container is described. The dispenser comprises a fluid supply arrangement for accepting a dispensing nozzle (76) of the container and providing a flow of pressurised fluid to the dispensing nozzle to enable the material to be dispensed as a spray. A moveable member (18) can be used to control the flow of pressurised fluid, for example a member disposed on a cap (14) for closing a container containing compartment of the dispenser and/or a moveable member (18) disposed around the dispensing nozzle (76). The arrangement of the fluid supply arrangement allows for convenient control of the pressurised fluid flow for spraying the material. Also disclosed is a dispenser with a readily exchangeable pressure application interface for applying a dispensing pressure to the container, enabling the dispenser to be used with both cartridge and foil pack containers. |
