ABSTRACT OF THE DISCLOSURE A device for dispensing a predetermined quantity of the contents of a container. The device includes a flexible container capable of being reversibly deformed by squeezing. The container has a neck defining an opening for dispensing contents when it is in a predetermined orientation. A chamber is mounted in the neck, and has a first end extending into the container and a second end aligned near the opening. A dispenser is mounted inside the chamber and includes a piston for leading flow of contents. The piston is sized to fit the chamber to form the front end of the predetermined quantity in the chamber. The dispenser also includes a seal for sealing the first end to form the back of the predetermined volume in said chamber. Deformation of the container forces the seal means to seal the first end and extend the piston beyond the second end to permit discharge of only the predetermined quantity of contents.
