Definitions

• the present invention relates to a device for packaging and dispensing a fluid product, and more particularly to a new device for packaging and dispensing a fluid product, liquid or pasty, of the type comprising at least two flexible bags placed in a single rigid container, associated to one or more pumps or valves, ensuring the storage of at least two fluid products protected from air and their distribution, in mixture or separately, under good conditions of efficiency.
• Devices for packaging and dispensing fluid of the bottle-pocket type are well known. They generally include a rigid shell container in which is placed a flexible pouch which retracts as the product is extracted therefrom.
• the expulsion of the product from the bag can be obtained by means of an "airless" pump, or without air intake, or under the pressure of a propellant acting in the bottle, on the wall of the bag.
• a vent is provided, generally at the bottom or in the neck of the bottle, to allow outside air to enter in the space between the bottle and the bag on each actuation of the pump and thus allow the bag to retract while maintaining sufficient pressure on its walls.
• the present invention specifically relates to a device for packaging and dispensing fluid, liquid or pasty products, of the type comprising at least two flexible waterproof bags placed in the same single rigid container, associated with one or more pumps or valves, ensuring a effective distribution of at least two products separately or as a mixture.

• the two pockets are formed in a single piece and are then in the form of a double pocket comprising two compartments separated by a partition, each compartment preferably having its own opening provided with a collar for fixing a pump.
• This embodiment has the advantage of stiffening the structure of the pocket by means of the partition, which has the effect of facilitating the return of the products contained in the pockets.

• Other shapes can be produced without difficulty, for example a substantially elliptical shape, or a shape any continuous or polygonal, or even a non-cylindrical shape, depending on the desired aesthetic effect or imposed by the shape of the rigid container.
• each pump adapted to each pocket can be actuated by an independent pusher, or, on the contrary, a single pusher can be actuated simultaneously actuating two or more pumps.

At the end of actuation of the pumps, the air circuit is automatically closed, which ensures optimal preservation of the products contained in the pockets by limiting evaporation through the wall of the pockets.
• the air circuit is constituted by a passage arranged in the edge of the ring, communicating with the space between the pump and the pusher, and comprising shutter means as long as the pump does not is not activated.
