  • the wavelength determined can for example be red and the piston is at least partially red.
  • the piston is a follower piston which moves when the fluid in the tank is under vacuum.
  • the spirit of the invention resides in the fact of remotely detecting the passage of the piston which moves in the barrel of the tank to provide visual and / or audible information to the user on the state of filling / emptying of the tank.
  • Remote detection can use any technology, such as induction (magnetic field detection or magnetic field disturbance detection), optics (color, reflection, refraction, diffraction), l capacitive effect, ultrasound, hall effect, Faraday effect, resistance variation, etc.
  • This dispensing and application set has an elongated or slender shape which can be similar to that of a pen or a felt. It can also be noted that its cross section is not constant, since it varies from bottom to top significantly. In this case, near its lower end, the dispensing and application assembly has a rather round or circular cross section, while at the level of the cutting line AA, which is rather located near the he upper end, the dispensing and application assembly has an ovoid cross section ( Figure 3 ). The upper face of the assembly forms an application surface S which has an inclination or slope towards one side.
  • the distribution and application assembly of the invention comprises three separate main entities, namely a distribution entity D, a receiving entity B and an application entity A.

  • the body 1, at the level of the compartment 1b is provided with a lateral pusher 15 which is movable transversely to the longitudinal axis of the receiving body 1.
  • the displacement of the pusher 15 can be done by pure translation or by elastic deformation.
  • the receiving body 1 can very simply be produced by injection molding of plastic material, or even of metal.
  • the application entity A here results from the association of an application head 2 and a wave generation module 3.
  • the application head 2 as can be seen in the Figures 1 and 2 , comprises an axial housing 22 formed by a cylindrical tube whose cross section has a complex geometric shape, for example that of a crescent.
  • This housing 22 is connected upwards to an application surface area 21 which is here formed with two openings, namely a first opening corresponding to the mouth of the housing 22 and a second opening for the module 3.
  • the module 3 comprises an application surface section 31 which closes the corresponding opening in the head 2 so as to continuously complement and smooths the application surface area 21 of the head 2.
  • the module 3 fits into the opening of the application head so that the application surface section 31 of the module 3 completes the range of application surface of the head 2 without creating discontinuity, protrusion or depressions. Consequently, the assembly of the module 3 and of the head 2 makes it possible to create an application surface S, the only opening of which, at this stage, is formed by the mouth of the housing 22.
  • the application head 2 also includes a peripheral skirt 23 which fits in the upper end 12 of the hollow body 1.
  • the wave generation module 3 extends inside the reception space 1c, and advantageously has a latching profile 34 capable of cooperating with the lower edge 14 of the partition 13. In this way, the application entity A can be mounted in a perfectly stable manner on and in the hollow body 1.
  • the wave generation module 3 makes it possible to generate any type of wave or electromagnetic, vibratory radiation, etc., such as, for example, visible light, infrared, ultraviolet, or even microwave, etc. or even ultrasound or mechanical vibrations.

  • the fluid dispenser or distributor D comprises a fluid reservoir 4, a pump 5 and a dispensing nozzle 6, as can be seen more clearly on the figures 6 to 8 .
  • the reservoir 4 may for example be in the form of a sliding barrel 41 in which is received a follower piston 42 which is adapted to slide in the barrel 41 as fluid is extracted from the tank.
  • the top of the barrel 41 forms a neck 45.
  • this particular reservoir one can also imagine a simpler reservoir without variation in useful volume, or even a reservoir with a flexible pocket.
  • the pump 5 comprises a fixing ring 54 allowing it to be mounted on the neck 45 of the reservoir 4.
  • the pump 5 comprises a pump chamber 50 provided at its lower end with an inlet valve 51, for example in the form of a slit shutter.
  • the pump chamber 50 comprises an outlet valve 52, which can for example also be produced in the form of a slotted shutter.
  • the pump chamber 50 comprises a lateral actuator 53 which makes it possible to reduce the useful volume of the pump chamber 50 and thus to discharge fluid product through the outlet valve 52.
  • the lateral actuator 53 is movable perpendicular to the longitudinal axis X of the distributor D. The displacement can be done translatively or by elastic deformation.
  • the actuator 53 is in the form of a flexible wall of the pump chamber 50 which has been produced for example by a bi-injection or overmolding process.
  • the pump 5 can thus be qualified as a flexible membrane pump, in the sense that one acts directly on a movable wall of the chamber to put the fluid product under pressure.
  • the pump 5 forms a mounting well 56 for the dispensing nozzle 6.
  • This mounting well 56 is advantageously provided with coding means 55, for example in the form of a projecting profile or of a recess, making it possible to impose the angular orientation of the nozzle 6 in the well 56.
  • the dispensing nozzle 6 thus comprises a mounting heel 65 which is engaged, and advantageously snapped into, inside the mounting well 56.
  • the mounting heel 65 comprises a keying profile which adapts perfectly in the means of coding 55 of the well 56, in order to impose the angular orientation of the dispensing nozzle 6 on the pump 5. In this way, the nozzle is always oriented in the same way relative to the lateral actuator 53, which extends only on one side of the pump 5.
  • the dispensing tip 6 forms an insertion appendage 63 whose cross section has a shape corresponding to that of the housing 22 formed by the application head 2. This shape is more clearly visible on the figure 7 : it is similar to a shape of a crescent.
  • the side wall of the insertion appendage 63 may be cylindrical, although not circular over its entire height.
  • one or more protruding sealing bead (s) can be provided for making a seal inside the housing 22.
  • the appendage 63 forms a substantially planar outlet surface 61 which is pierced with a dispensing orifice 62, forming the outlet of an outlet duct 60 which passes through the appendix 63 and the mounting heel 65, as can be clearly seen on the figures 2 and 6 .
  • the outlet valve 51 communicates directly with the outlet duct 60.
  • the useful volume of the pump chamber 50 is reduced, and the fluid under pressure is discharged to through the outlet valve 52, from where it can flow through the outlet conduit 60 to the dispensing orifice 62 located at the outlet surface 61.
  • the outlet valve 52 closes and the inlet valve 51 opens under the effect of the vacuum created in the pump chamber 50, thus making it possible to suck fluid product coming from the reservoir 4, the follower piston 42 of which then moves towards the pump 5.
  • the distributor entity of the distributor D is inserted inside the hollow body 1 through its lower end 17, after removal of the removable bottom 7.
  • the distributor D is thus inserted axially through the space 1a, then through the space 1b until the dispensing nozzle 6 penetrates inside the housing 22 of the application head 2.
  • the angular orientation is preferably unique. It is then possible to fully engage the appendix 63 inside the housing 22 until the outlet surface 61 reaches the level of the application surface S so as to complete it. This is visible on the figure 2 .
  • the outlet surface 61 comes perfectly flush with the surface of the application surface 21 of the head 2 so as to complete it. In the end, only the dispensing orifice 62 breaks the continuity of the application surface S.
  • the removable bottom 7 the flexible material of which 64 comes into contact with the bottom of the reservoir 4 to push it upwards, and seal the housing 22.
  • the lower end of the reservoir 4 projects from the hollow body 1 when the bottom removable 7 is removed, so that the dispenser can easily be grasped by its reservoir 4 to extract it from the hollow body 1.
  • the dispenser D is removably received inside the hollow body 1 and the head 2.
  • the imposed angular orientation of the appendix 63 inside the housing 22 allows the lateral actuator 53 to be placed opposite the pusher 15 of the hollow body 1.
  • the application entity A is removably received on and in the reception entity R.
  • the distributor distribution entity D is also removably received inside of the receiving entity R and inside the housing 22 of the application entity A.
  • the distributor D and the application entity A can be replaced at will as required.
  • a particular distributor distributing a particular fluid product is associated with a particular application entity. It then suffices to mount the two entities A and D in the receiving entity R to constitute the distribution and application assembly of the invention. If it is necessary to replace entities A and D, this is easily possible by removing them each from the receiving entity R.
  • the fluid dispensed by the dispenser D only leaves the dispenser at the level of the application surface S, so that there can be no fluid remaining inside the receiving entity R, once the dispenser has been removed.
  • the application surface S is perfectly continuous and smooth, it can be easily cleaned by rubbing or wiping.
  • the wave generation module 3 forms an application surface sector 31. This is only a particular non-limiting embodiment, since it is quite conceivable to produce the wave generation module 3 without it forming part of the application surface S.
  • the module 3 can for example be associated with the application head 2 just below the application surface S, which will then serve as diffusion means for the waves.
  • this distribution assembly is further provided with means for giving an indication or visual and / or audible information to the user of the assembly as to the filling / emptying state of the reservoir 4.

  • a volume of 10 mm3 to 50 mm3 is possible, with a preference, in order, for 40 mm3, 30 mm3 and 20 mm3. It would be advantageous if the attraction force of the magnet M is low enough that the follower pistons 42 do not adhere to each other, in order to facilitate their handling in the assembly lines.
  • the follower piston 42 is caused to move over a maximum stroke whose low initial position is shown on the figures 1 and 6 and a high end position which is represented on the figure 2 . It can also be said that the piston 42 slides between a starting position corresponding to a substantially full state of the tank and an arriving position corresponding to a substantially empty state of the tank.

  • detection means in the form of a magnetic field disturbance sensor emitting a magnetic field and a piston comprising an element capable of disturbing the magnetic field generated by the magnetic field disturbance sensor.
  • One can also envisage an optical sensor sensitive to the reflection of light produced by reflective particles or a coating carried by the piston.
  • a distribution assembly comprising a reservoir in which a piston (follower or pusher) moves, and the filling / emptying state of which can be communicated to the user by means of remote detection.
