A device for dispensing fluid from a container has a tubular and flexible metering chamber, intended to be squeezed by a hand. The metering chamber is closed by means of a self-closing closure, which however opens in response to a predetermined pressure upon the fluid. A floating body housed in said metering chamber limits the squeezing of the metering chamber and breaks, when floating in a sufficient amount of fluid in the metering chamber, the communication between the container and said metering chamber.

A device for dispensing fluid from a container, said device comprising a vertically oriented metering chamber including a flexible tube forming at least a portion of the side walls of the chamber, the tube having the interior thereof in communication with said container through an inlet in the upper end of the chamber, said inlet forming a valve seat through which fluid can flow from said container into said metering chamber, an elongated floating member housed in said chamber, said member acting as a valve for opening and closing said inlet under pressure of the level of fluid in said metering chamber, said metering chamber also having an outlet in its lower end for dispensing liquid, and a self-closing closure in said outlet for opening said outlet under a predetermined pressure upon the fluid in said metering chamber, said floating member being dimensioned with respect to said tube for permitting fluid to rise between the sides of the floating member and the inside of said tube for determining the amount of fluid to be dispensed upon squeezing the tube inwardly against the sides of the floating member, the larger the area of the tube squeezed against the floating member the larger the amount of fluid dispensed in a single squeezing action.
