  • the disk or counting wheel 10 also comprises indicating means 15, which may be numbers and / or symbols and / or colors, and which are intended to indicate the number of doses dispensed or still to be dispensed. These means of indication 15 advantageously follow at least partially said hollow profile 18. Any combination of different means of indication 15 is also conceivable.
  • the indicator A shown in the figures further comprises a translational member 20 adapted to move in translation.
  • This translational member 20 comprises a projection 28, or any other equivalent means, which cooperates with said hollow profile 18 of the rotating disk 10.
  • This translational member 20 is preferably made in the form of a thin plate, and comprises a viewing opening 25 intended to cooperate with the indication means 15 of the rotating disc 10.
  • a rotation of the counting wheel 10 can cause a translation of the translational member 20.
  • the profile 18 is made so that the indication is progressive and not regular.
  • the indicator of Figures 3 to 9 can be counted about 200 doses, the last 50 being displayed in increments of 5 in the viewing aperture 25 of the translational member 20.
  • the hollow profile 18 is first spirally in the center of the disk 10, so that each rotation of said disk 10 causes a translation of said translational member 20.
  • the profile 18 becomes cylindrical, so that the following rotations of the disc 10 no longer move the translational member 20.
  • the indication digits 18 are then displayed in the viewing opening 25 as and when actuation of the device.
  • figure 10 shows an alternative embodiment, wherein the indicator can be counted 120 doses, the progressive indication being effected by gap 10 between the first and the 60th dose and at intervals of 5 then. Other progressions are also possible.

  • actuating means integrated into said indicator A.
  • these actuating means may advantageously comprise a drive element 31 integral with a ring 30 which surrounds said toothing 19 of the rotary disk 10.
  • This drive element 31 is adapted to cooperate with said toothing 19 each time that a dose is dispensed, preferably by means of an actuating tooth 35.
  • anti-return means 36, 37 for preventing said rotary disc 10 from rotating in the opposite direction to that given to it by the driving element 31 during actuation.
  • These non-return means may comprise a flexible tab 36 supporting a non-return tooth 37 cooperating with the toothing 19.
  • the actuating means also advantageously comprise a transmission element 34 which is adapted to cooperate with the fluid product distribution device B, at each actuation thereof, said transmission element 34 cooperating with said element of the other part. 31 to rotate said rotary disk 10.
  • said transmission member 34 is a shoulder integral with the drive member 31 and which cooperates with a portion 54 of the fluid dispensing device B which is movable during actuation. In the example shown, it is the fixing ring 54 of the metering valve 52 on the tank 51.
  • any part that moves during the actuation of the device B is adapted to cooperate with the shoulder 34 to actuate the dose indicator A.
  • the actuating means comprise at least one flexible lug 31 forming the driving element, this flexible lug 31 being provided with two flexible portions 32 and 33 of different flexibility, the portion 32 being more flexible than the portion 33.
  • the portion 33 is wider than the portion 32.
  • the flexible tab 31 supports said shoulder 34, and when the spraying device B is actuated, the fixing ring 54 of the reservoir first drives the more flexible portion 32 of the arm 31. to bend parallel to the rotating disc 10, which causes the rotation of said disc 10 by means of the actuating tooth 35 which cooperates with the toothing 19.
  • the flexible tab 31 advantageously comprises a locking element 38 adapted to cooperate with a stop protruding 39 integral with the ring 30.
  • the radial distance between the locking element 38 and the stop 39 corresponds advantageously to a tooth of the toothing 19.
  • the shoulder 34 is moved (downwards in the figures) by the dispensing device B, and the more flexible arm portion 32 bends (also downward in the figures), until the locking element 38 contact with the stop 39.
  • This causes rotation on the equivalent of a tooth of the counting wheel 10.
  • the more flexible arm portion 32 is then blocked, and a continuation of the actuating stroke of the dispensing device B is prevented. possible by bending the less flexible arm portion 33. In this way, actuation of the dose indicator is enabled in the first portion of said actuating stroke.
  • Stop 39 and the non-return means 36, 37 ensure that each dose is counted only once.
  • the cover 40 comprises guide means 41, such as rails or ribs, which cooperate with the translational member 20 to guide it in its displacement in translation.
  • guide means 41 such as rails or ribs
  • the number of teeth on the toothing 19 and the shape of the hollow profile 18 of the counting wheel 10 therefore give the characteristics of the dose indicator, and in particular the number of doses that this indicator can count. So, in the example shown on the figure 3 to 9 a dosage indicator adapted to have about 200 doses is shown, the last 50 being digitally displayed at intervals of 5 in the display opening 25 of the translational organ.
  • the maximum number of doses and the display mode can be varied as desired by modifying the structure of the profile 18, the indicating means, or the number of teeth on the toothing 19.
  • the present invention therefore makes it possible to achieve dose indicators adapted to count any number of doses, without changing the geometry or size of said indicator.
  • the dimensional structure of this indicator is particularly small, especially in the dimension of the thickness, and this indicator A can therefore very easily be integrated into the existing fluid dispensing devices B, as is visible on the figures 1 and 2 .
  • the dose indicator of the present invention makes it possible to display in a simple, inexpensive and progressive manner the number of doses dispensed or the number of doses remaining to be dispensed in the device.
  • the structure of the indicator is very thin, regardless of the number of doses it must indicate, and it has no protruding part involving a modification of the device to which it is applied.
  • the dose indicator A of the present invention applies very easily to all existing devices, without these must be modified.
  • the presence of the indicator A also does not modify the assembly process of the device B.
  • the indicator can for example be put in place in the device B through a device. opening provided for this purpose on the front of the body 50 of the device.
  • Another advantage of this indicator is that the actuator means of the indicator are integrated therein, so that the indicator forms a separate and autonomous unit which can be pre-assembled, and easily integrated into any which fluid dispensing device.
