Patent number: 7419322Abstract: The fluid dispensing device (10) includes a container (20) with an interior fluid storage region (22) therein. A flexible metering housing (26) is disposed in fluid communication with the fluid storage region (22) a first one-way valve (30) disposed between the container (20) and the flexible metering housing (26). One way flow from the interior fluid storage region (22) of the container (20) fills the predetermined volume of the metering chamber (32) with fluid by vacuum action when a button (36) is depressed and then released. A second valve (40) is in fluid communication with the metering housing (26) and permits one-way fluid flow from the metering chamber (32) to the exterior outer region of the container (20) when the metering housing (26) is depressed again. Each time the metering housing (26) is depressed a substantially equal volume of fluid (24) is dispensed from the container (20). An additional foam layer (12) on the outside of container (20) facilitates dispersion and delivery of the fluid (24).Type: GrantFiled: March 8, 2005Date of Patent: September 2, 2008Assignee: Poly-D LLCInventors: Roger J.
