The invention relates to a device with a membrane for dosing viscous substances contained in a reservoir. It consists of a stopper (2) provided with a hollow part (4). A flexible membrane (5) is fixed to the stopper (2). When the user exerts a pressure on the viscous substance, the membrane (5) inflates, allowing the filling of the dosing stopper. After opening, the user empties the contents of the dosing stopper by pressing on the membrane (5). <IMAGE>
