Abstract: A fluid substance dispensing device includes an external container with a containment element formed of a deformable part and an essentially rigid neck featuring a first flange which abuts with a free end of the external container at one of the mouth thereof, an intermediate element with a cup-shaped part inserted into the neck and fastened to the external container so that the first flange is sandwiched between the free end and the intermediate element, the cup-shaped part including an opening in communication with an internal part of the deformable part, there being—inside the cup-shaped part—a valve element configured for displacement by the body of an airless pump so that, when the body of the pump is absent or in an unused position, the valve element is stably closed, while when the pump body is pushed into a use position, the valve element is stably open.
