Patent number: 8434647Abstract: The present invention discloses a device for measuring and dispensing a prescribed amount of liquid. The advantage of the present device is that a simple squeezing action not only reliably and precisely stores a prescribed volume of liquid (e.g., a liquid cooking ingredient, beverage (such as wine or liquor) but then subsequently upon an additional squeeze, discharges the stored liquid while refilling the dose chamber with another dose of the prescribed volume to be later discharged upon the next squeezing action. This eliminates the time consuming tasks of having to measure liquids with conventional measuring cups and the like and instead, the user simple initially adds liquid to the container and then places the cover and measuring and dispensing mechanism on top of the container prior to performed successive squeezing for loading and discharging the dose volume.Type: GrantFiled: July 14, 2010Date of Patent: May 7, 2013Inventor: Riad Aamar

Patent number: 4151934Abstract: A fixed volume discharge device adapted to be mounted to a container, and having a first chamber communicating with the interior of the container and a second chamber communicating with the atmosphere, the first chamber and the second chamber communicating with each other through a restricted opening. A liquid or powder stored in the container flows into the first chamber when the container is downwardly inclined, and then flows into the second chamber from the first chamber when the container is returned in its normal attitude. Thus, when the container is again downwardly inclined, the liquid or the powder within the second chamber is discharged while the liquid or the powder in the container flows into the first chamber, thereby a predetermined fixed volume liquid or powder is obtainable through the fixed volume discharge device each time the container is downwardly inclined.Type: GrantFiled: October 12, 1977Date of Patent: May 1, 1979Inventor: Noriyoshi Saeki
