Definitions

• the present invention relates to a fluid dispenser comprising two sheets forming between them a fluid reservoir. At least one of the two sheets defines a deformable actuating wall which can be pressed so as to reduce the volume of the reservoir.
• the reservoir can also advantageously be provided with elastic means such as a spring urging the reservoir towards its maximum volume.
• the fluid dispenser includes a dispensing part which is tightly fixed between the two sheets and which defines a dispensing orifice through which the fluid from the reservoir is dispensed by pressing on the deformable actuating wall. .
• such a fluid dispenser comprises two sheets forming a collapsible reservoir so as to eject the product which it contains through a dispensing orifice formed by a part fixed between the two sheets.
• a removable closure element which closes the dispensing orifice.
• the removable closure element closes the dispensing orifice and the reservoir is substantially flat so as to define a minimum volume containing substantially only fluid.
• the elastic means included inside the tank are then completely constrained so that the dispenser is in a very flat configuration.
• air enters the tank through the dispensing orifice which allows the elastic means to relax inside the tank which then takes a configuration of rest in which it defines a maximum volume.
• By then deforming the reservoir by pressing on the actuating wall, a two-phase mixture of fluid and air is expelled through the dispensing orifice with perfect spray quality.
• the present invention aims to improve such a fluid dispenser as defined in the aforementioned document.
• the present invention seeks in particular to improve the aesthetics and the functional characteristics of the reservoir as well as of the distribution part.

• the two concentric welds ensure perfect flatness of the periphery of the distributor surrounding the reservoir. This perfectly flat periphery is useful for affixing indications such as the brand, the nature and the use of the fluid contained in the dispenser.
• the two weld lines meet at several points, for example at the level of said distribution piece, so as to define one or more zone (s) not welded (s).
• the second internal weld line defines a line of convergence of the reservoir oriented in the direction of said dispensing part in order to converge the contents of the reservoir in the direction of the dispensing orifice.
• the first weld line forms a spring housing in which the elastic means are at least partially received.
• the two sheets include a detachable closure tab located in front of the dispensing part at the dispensing orifice to isolate the reservoir from the outside before use.
• the closure tab is formed by a part of the sheets welded together and having a sealed sheet-part-sheet contact point on either side of the dispensing orifice.
• the dispensing part comprises a front face forming the dispensing orifice, two lateral sides, and a rear face facing the reservoir, said rear face forming a receiving housing in which a porous material is inserted, said housing comprising a bottom wall in which is formed the dispensing orifice and the element of porous material extending from this bottom wall into the reservoir so that it can be imbibed with product fluid, the rear face forming on either side of the receiving housing a convergence wall oriented towards the receiving housing, the element of porous material comprising a head engaged in the housing and a body extending in the tank, the body forming on either side of the head a guide wall oriented towards the head, each guide wall extending substantially parallel to a wall of convergence respec tive of the dispensing part so as to form between them two convergence and guide channels for directing the contents of the reservoir towards the dispensing orifice.
• convergence and guide channels terminate directly at the head of the element of porous material, therefore directly near the dispensing orifice. This ensures a perfect mixture of air and fluid which contributes to improving the quality of spraying at the outlet of the dispensing orifice.
• the two convergence walls which are located substantially in the extension of the lines of convergence formed by the reservoir, also serve to guide the air under pressure in the reservoir towards the dispensing orifice.
• the lateral sides of the dispensing part have thin tapered edges at which the sheets welded are in tight sheet-piece-sheet contact. This ensures perfect sealing at the level where the two welded sheets meet the dispensing part.
• the front face comprises: - a distribution wall substantially perpendicular to the orientation of the distribution orifice and in which the distribution orifice is formed, and thin edges tapered on the side and on the other side of the distribution wall at which the welded sheets are in sheet-part-waterproof sheet contact.
• the two welded sheets which extend at the level of the front face of the dispensing part form the removable closure tab defined above.
• the dispensing piece has a thickness of less than about 2 mm, so that the dispenser has a thickness of less than about 2mm before use.
• the double welded line reheated at the level of the two sheets need not necessarily be combined with a distribution piece forming convergence and guide channels.

• the two sheets 1, l are also welded together along a second line of weld 12 which is surrounded by the first weld line 10 and which is connected to the latter on one side of the body 11 '.
• These two weld lines 10 and 12 define one or more non-welded zone (s) 11.
• FIG. 1 there is a single U-shaped zone which surrounds the second weld line 12. This non-welded zone welded 11 is perfectly flat, since it is bordered on all sides by weld lines.
• the second weld line 12 defines a reservoir 15 formed with a bottom 120 and side walls 121. At its upper end, the reservoir 15 is closed by the distribution piece 2 which is welded between the two sheets 1, the substantially at level of the junction between the first and second weld lines 10 and 12.
• the reservoir 15 contains fluid, advantageously in small quantity, as well as a spring 4 which serves to separate the two sheets 1, one of the other at the level of the reservoir 15 and thus define an internal volume which is the useful volume of the reservoir 15.
• a spring 4 which serves to separate the two sheets 1, one of the other at the level of the reservoir 15 and thus define an internal volume which is the useful volume of the reservoir 15.

• This element of porous material 3 is formed with a body 30 which extends in the reservoir 15 and a head 31 which serves as a nozzle. fixing in a housing 23 formed by the distribution piece 2.
• the housing 23 comprises a bottom wall 240 in which is formed a distribution orifice 24 through which the fluid and the air contained in the reservoir 15 are expelled under pressure so as to form a two-phase jet sprayed with fluid and air at the outlet of the dispensing orifice 24.
• the head 31 of the element of porous material 3 is for example engaged by force in the housing 23 so that the end of the head reaches the level of the dispensing orifice 24 as can be seen in FIG. 1.
• This housing 23 for the head 31 of the element of porous material 3 is formed on the rear face of the distribution piece 2.
