Abstract
A device for storing a liquid or pasty product and for dispensing a given quantity of the product includes a container that contains the product. A stopper is disposed at an upper end of the container. A dip tube extends through a channel of the stopper and into the container. A sealed enclosure receives the container such that the container can be subjected to a pressure higher than a pressure outside of the enclosure. A weighing element of the enclosure measures the weight of the container when the container is received in the enclosure. A controller controls a mechanism for pressurizing the enclosure by comparing a change in weight of the container with a set value that corresponds to a predetermined quantity of product to be ejected from the container, and interrupting pressurization of the container when the change in weight of the container has reached the set value.
