  • Publication number: 20090020621
    Abstract: 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 ?m 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.

  • Patent number: 7426799
    Abstract: A display frame with a refill holder comprises a transparent block with front and rear faces. A U-shaped mounting member is attached to the rear face about an outer periphery of same. The U-shaped mounting member has an inwardly extending wall. A channel is formed in a space between the rear face and the inwardly extending wall. A protrusion is attached to the rear face of the frame, wherein the protrusion in combination with the inwardly extending wall are configured to distance the rear face from a support surface when the frame is in a substantially horizontal position and provide a substantially unimpeded air passage adjacent the rear face.

  • Publication number: 20080093475
    Abstract: A refill for a volatile material includes a container having a reservoir portion and a neck portion. The refill further includes a plug assembly disposed within the neck portion of the container and a channel through a central portion of the plug assembly. Still further, the refill includes a porous wick extending through the channel, wherein the wick includes an upper portion extending outside the container and a lower portion disposed within the reservoir portion. A slit is formed in the lower portion of the wick to form a barb that catches on the plug assembly to prevent removal of the wick from the container.
