ABSTRACT:
A device for packaging and dispensing a fluid, including a receptacle containing a shrinkable bag suitable for shrinking as the quantity of fluid contained inside it diminishes, the device also including extraction means opening out to the inside of the bag. Inside the bag, the device includes a free body whose buoyancy is selected so that it takes up a position close to the extraction means when the device is in use for dispensing a quantity of fluid, the shape and the dimensions of the body also being selected so as to prevent the bag from tearing as it shrinks.
