Abstract
A dispensing device for use with a variety of containers and contents such as wine and artist's paint. The device has two parts: a stationary member having three flexible flanges for engaging a container and providing a seal, a central disc and a screw thread; and a movable member having a sealing end portion, a measuring throat, a gripping surface and a drip edge. The sealing end portion provides a seal with the disc when the device is in a closed position. The device is simply constructed, reliable and relatively inexpensive.
