摘要：A dispenser for a fluid substance, esp. used in cosmetics or pharmaceuticals,consists of a cap (1) which fits onto the container (2) and made with at least one outletchannel (8). The/each outlet channel has a system which closes its outlet, made in theform of a shutter (9a) which is able to deform elastically and interact with a seat (8e). Thedeforming shutter and seat form a self-closing valve which is opened by the pressure ofthe fluid passing through it but closes once the pressure stops. The shutter is pressedtowards the seat by a support which limits its deformation. The pressure which expels thefluid from the container can be of various types, e.g. a pump piston or flexible bulb.
