Abstract: An aerosol system for dispensing liquid material. The aerosol system includes an aerosol assembly, a plurality of accessory members, and an accessory storage system. The aerosol assembly contains and dispenses liquid material. The accessory members are used in conjunction with the dispensing of the liquid material. The accessory storage system allows the one accessory members to be removably secured relative to the aerosol assembly using the deliberate application of manual force. Each accessory member operates in a first configuration in which the accessory member is not secured relative to the aerosol assembly and in a second configuration in which the accessory member is secured relative to the aerosol assembly. Optionally, the accessory members may operate in a third configuration in which the accessory member is integrally formed with the accessory storage system.

Abstract: Dispensing systems and methods for stucco and similar materials. The system comprises a dispensing assembly and a cartridge assembly. The dispensing assembly comprises a piston pushing assembly, an outlet assembly, and a structural assembly for holding the piston pushing assembly in a fixed relationship to the outlet assembly. The cartridge assembly can contain the material to be dispensed and is mounted within the dispensing assembly. Operation of the piston pushing assembly forces stucco or other material to move from the cartridge assembly to a mixing chamber portion defined by the outlet assembly. At the mixing chamber portion, the stucco material is mixed with a stream of pressurized air which carries the mixture out of the system and deposits the material onto a surface to be coated. The system allows substantial control over the manner in which the stucco or other material is sprayed.
