Abstract: The device includes a dispensing end; an attachment end; and a dispensing valve provided between the attachment end and the dispensing end and formed by a flexible member and a rigid member. The dispensing valve is actuatable between an open position in which a dispensing channel is formed between the flexible member and the rigid member, and a closed position in which the dispensing channel is closed. The dispensing valve includes a first valve portion and a second valve portion. The second valve portion is located closer to the dispensing end than the first valve portion. The dispensing valve is configured such that a greater biasing force is applied onto the rigid member by the flexible member in the first valve portion than in the second valve portion when the dispensing valve is in the closed position.

Abstract: The device (100) for packaging and dispensing a product, liquid or in gel form, optionally for an ophthalmic application, comprises a container (1) containing the product to be dispensed by a dispensing head (7), as well as a refilling and filtering assembly for the air entering the container (1) after a dispensing, the dispensing head delimiting one or more dosing chambers (5) and including at its end a flexible part (7) which can be actuated to allow the release of the dose of product in a compressed state of said chamber (5). The air refilling and filtering assembly has a sterilizing filter (11) which cooperates with a check valve (12), this assembly (11, 12) being typically located in a central or inner portion of the head (7). The supply of outside air is accomplished by means of a channel (16) leading to an outer orifice (10) able to be obturated by a cover (15).

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.
