Patent

CA 2637867

An aerosol dispenser assembly is disclosed that includes a container holding a liquid product and a compressed gas propellant for propelling the liquid product from the container. A design methodology for the actuator body and swirl nozzle insert is disclosed for maintaining a small particle size or Sauter Mean Diameter (D[3,2]) of less than 48 µm at a suitable spray rate (1.5-2 g/s), while utilizing a compressed gas VOC-free propellant for an air freshener product. As obtaining reduced particle size to compete with LPG propellants may result in a reduced spray rate, it is anticipated that one or more nozzles may be designed into the actuator body to maintain a suitable spray rate.

La présente divulgation décrit un distributeur en aérosol qui comprend un récipient qui contient un produit liquide et un gaz comprimé propulseur du produit liquide provenant du récipient. Une méthode de conception du corps de l'actionneur et de la garniture de la buse à turbulence est divulguée pour maintenir la grosseur des particules petite ou le diamètre moyen de Sauter (D¬3,2|) inférieurs à 48 mu.m, au débit approprié (1.5-2 g/s), tout en utilisant un gaz comprimé propulsif sans COV pour purificateur d'air. Étant donné que l'obtention d'une grosseur de particules petite pour rivaliser avec les propulseurs GPL peut résulter en un débit réduit, il est prévu pour l'intérieur du corps de l'actionneur une ou plusieurs buses pour maintenir un débit approprié.
