Abstract
The device for packaging and dispensing a product comprises a container (1) intended to contain in a sterile manner the product to be packaged and dispensed in the form of calibrated doses or drops by means of a dispensing accessory equipped with a mouthpiece (4) of the type having a flexible part (5), said accessory forming a dosing chamber (7) for the dispensing of the calibrated drop. An outer wall (8) of the mouthpiece delimits a space (18) equipped with one or more openings (19), the end of said mouthpiece (4) including a central channel (13) allowing the dispensing of the calibrated drop, associated with one or more lateral channels (11) leading into the space (18). A cover (14) equipped with an inner skirt (15), in the mounted state, creates an overpressure so as to eliminate any residual drop (10) which can subsist in the mouthpiece (4) at the end. Application to the dispensing of doses of sterile products, particularly of drops in ophthalmology.
