Definitions

• the present invention relates to a device for spraying a fluid product, such as perfume, capable of producing a cloud of fine droplets.
• pumps and valves are already known which make it possible to create a spray of fluid product by pressing a pusher or by crushing a reservoir of fluid product.
• Document FR2846306 is also known, which describes a fluid dispenser comprising a fluid reservoir of variable volume, defining a movable wall so as to vary the volume of the reservoir.
• the dispenser further comprises a dispensing orifice in communication with the reservoir, so that the fluid from the reservoir can be discharged, when the volume of the reservoir decreases, through the dispensing orifice.
• This dispenser comprises two actuating walls between which the reservoir is arranged. These actuating walls make it possible, firstly, to increase the volume of the reservoir by air entering the reservoir and, secondly, to reduce the volume of the reservoir by discharging air and fluid. through the dispensing orifice. More precisely, it is the differentiated curvature of the two actuating walls which thus makes it possible to vary the volume of the reservoir.
• the aim of the present invention is to be able to spray a fluid product by means of the deformation (bending, bending, bending, etc.) of a single wall supporting the fluid, in the manner of an orange peel which generates gasoline sprays when folded.
• the orange peel includes a layer called “epicarp” which contains gasoline glands.
• the epicarp covers a deep layer called the “mesocarp”.
• the gasoline glands are put under pressure and the epicarp will split, allowing the essence to escape through the slits in the epicarp, which act as a spray orifice.
• the gasoline is then distributed in the form of fine droplets.
• a goal of the invention is to artificially recreate the structure of the orange peel and more particularly its ability to create sprays when it is folded.

• a foldable substrate defining two opposite edges and a folding zone arranged between the two opposite edges, the two opposite edges being able to move closer to each other by folding the folding zone,
• the pliable substrate corresponds to the mesocarp and the carrier layer containing the fluid corresponds to the epicarp. Folding the assembly generates small sprays of fluid through a plurality of spray ports.
• the spray device can further comprise a spray wall which is disposed on the carrier layer, the spray wall forming spray orifices.
• the spray orifices are created when the bendable substrate is folded, advantageously from fracture initiators.
• the spraying device may further comprise a film disposed on the carrier layer or on the spraying wall, this film being removed before folding the foldable substrate.
• this film can also call this film a peelable seal. It is up to the user to remove it before folding the substrate.

• the carrier layer forms cuvettes filled with fluid and sealed by the spray wall. It can then be in the form of a closed cell foam, the upper face of which defines cavities, depressions, reliefs, basins, etc. making it possible to collect fluid.
• the foldable substrate can have a slight curvature in the rest state, in order to induce the direction of the fold.
• the film may for example constrain the foldable substrate into a planar state, so that after removal of the film, the foldable substrate returns to a slightly curved rest state. It is also conceivable that the underside of the foldable substrate is curved or concave.
