A device for containing and dispensing a fluid product, such as a cosmetic product, in the form of a spray. The device includes a reservoir containing the product at substantially atmospheric pressure, with the reservoir having flexible walls that preferably do not have shape memory. The device is equipped with a spray member for spraying the product in response to pressure exerted on the flexible walls of the reservoir, and an anti-air-intake element provided in order to prevent any entry of air inside the reservoir when said pressure ceases. When pressure is applied, the walls are deformed 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 entering the container. As a result, the next spraying action occurs more immediately and consistently because the container remains substantially filled with the product as the volume of the container is reduced upon deformation of the container walls.
