The device for packaging and applying a product, notably a liquid cosmetic product, comprises a container delimiting an internal reservoir for storing said the product, and comprising an opening providing access to the reservoir, a closure member mounted removably on the container so as to move between a position in which the container is closed and an open position, and a member for applying the product. The closure member bears the application member. The container internally comprises a narrowing of the section delimiting the opening providing access to the internal reservoir of the container. The application member extends at least in part through the access opening, sealing the said opening closed when the closure member is in the closed position, the application member being situated outside the container when the closure member is in the open position.
