摘要：A device for containing and dispensing a fluid product, such as a cosmeticproduct, in the form of a spray. The device includes a reservoir containing the product atsubstantially atmospheric pressure, with the reservoir having flexible walls that
preferably do not have shape memory. The device is equipped with a spray member forspraying the product in response to pressure exerted on the flexible walls of thereservoir, and an anti-air-intake element provided in order to prevent any entry of airinside the reservoir when said pressure ceases. When pressure is applied, the walls aredeformed and the product is sprayed from the container. After dispensing is completed,the walls are maintained in the deformed state because air is prevented from enteringthe container. As a result, the next spraying action occurs more immediately andconsistently because the container remains substantially filled with the product as thevolume of the container is reduced upon deformation of the container walls.
