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.
