Abstract
A method for manufacturing a device for dispensing a product, including a supply of a device having a reservoir, the reservoir being connected to a deformable chamber and being provided with a filling opening, the inside of the deformable chamber being delimited at least in part by a movable wall whose displacement causes a variation of the volume of the deformable chamber; an evacuation step in which a depression is created in the deformable chamber with respect to a reference pressure; a filling step in which the reservoir is filled with product, so that in a so called 'intermediate' state of the device, the reservoir is filled with product while the inside of the deformable chamber is at an intermediate pressure lower than the reference pressure; and a closing step in which the filling opening is sealed.
