Abrégé

The device for packaging and dispensing a product (2) comprises a container (1) containing the product (2) to be dispensed, a dispensing accessory (3) having a nozzle (7) with a flexible portion incorporating one or more metering chambers (9), and an air renewal assembly comprising an inlet duct (12), and a filter (13) cooperating with a valve (14). The product (2) in the container (1) is expelled to the outside when the chambers (9) are compressed, without air being able to enter the container (1) via the nozzle. A non-return valve (10) allows the product (2) to pass into the chambers (9) in the absence of loading but prevents the product (2) from returning into the container (1) when the chambers (9) are compressed. One or more elastic tongues (8) are provided cooperating with the flexible part (7) of the nozzle in order to make the operation of the device easier, by urging the nozzle from the inside towards its deployed position with a maximum perimeter.

The device for packaging and dispensing a product (2) comprises a container (1), a dispensing accessory (3) having a nozzle with a flexible portion incorporating one or more metering chambers (6). The product (2) in the container (1) is expelled to the outside when the chambers (6) are compressed, without air being able to enter the container (1) via the nozzle. A check valve (10) allows the product (2) to pass into the chambers (6) when they are no longer acted upon but prevents the product (2) from returning into the container (1) when the chambers (6) are acted upon. An assembly for renewing the air entering the container (1) after the delivery of a portion of the product (2) is provided with a central duct (9), an outlet and a non-return valve (5). A cover (14) having a skirt (16) makes it possible to create an overpressure in the container (1) by compressing air in a region adjacent to the outlet in order to reintroduce the residual drop (13) into the container (1) while facilitating the renewal of the air in the device.

Abrégé

The invention relates to a device for packaging and dispensing a liquid product which is semi-fluid or in suspension, said device comprising a container (1) containing the product (2) to be dispensed by an accessory (15) that can comprise at least one dosing chamber (16), as well as a renewal and filtration assembly (4, 5), the dispensing accessory (15) comprising a flexible portion (8) which cooperates with a rigid portion (7) so as to release a dose of the product (2) when the walls of the container (1) or the dosing chambers (16) are compressed but do not allow the outside air to penetrate inside the device when the actuating walls are no longer sollicited, the area of contact between the rigid portion (7) and the flexible portion (8) being interrupted and formed from sealing rings (13, 13a, 13b et 13c) arranged circularly inside the flexible portion (8). The invention is applicable to the packaging and the dispensing of doses of sterile products, particularly drops used in ophthalmology.

Abrégé

The device for packaging and dispensing a generally fluid product comprises a rigid container (1) intended to contain the product (11) and a dosing assembly made up of a nozzle (3) with a flexible part engaging with a rigid seat. A movable actuating portion (35), reinforced by an external layer (40) in order to be rendered non-deformable, allows the product to be dispensed when a force is applied to said actuating portion (35), compressing a dosing chamber (34). The dosing assembly (2) comprises a rigid portion (41) to which the external layer (40) is connected in an articulated manner and/or with a return action towards the outside of the external layer (40) when the application of a force to the actuating portion (35) stops. Application to the packaging and dispensing of sterile products, in particular pharmaceutical or cosmetology products.

Abrégé

The invention relates to a device for packaging and dispensing a generally liquid or viscous product, including a container (1) for containing the product (2) to be packaged and dispensed in the form of clean or sterile calibrated doses or drops (11) using a dispensing accessory including a tip, wherein the assembly of the container (1) and the accessory includes an additional flexible and deformable chamber (18) actuated simultaneously with the accessory and capable of either sucking the residual drop (12) at the end of said accessory after dispensing a calibrated dose or drop (11), or of blowing said calibrated dose or drop (11) without permitting the formation of a residual drop (12). The invention can be used for packaging and dispensing clean or sterile products, in particular doses or drops in the field of ophthalmology.

Abrégé

The device for packaging and dispensing a liquid, semi-fluid or viscous product comprises a rigid container (1) and a flexible pouch (2) containing the product (15) to be dispensed via a nozzle (6), the nozzle (6) of the container (1) is provided with at least one flexible part (10) from which the force exerted thereupon causes the product to exit, and a first check valve (9) assigned to the nozzle (6) for permitting the product to exit when the flexible part (10) is acted upon without letting outside air in when the flexible part (10) is released, the first check valve (9) being assigned to a second check valve (12) that permits the product (15) to enter the nozzle (6) when the flexible part (10) is released without letting the product (15) contained in the nozzle (6) to enter the flexible pouch (2) when the flexible part (10) is acted upon. The invention is for use in the packaging and dispensing of sterile products, in particular, ophthalmological drops.
