Definitions
- the present invention relates to a dose counter to indicate to the user the number of doses dispensed or remaining to be dispensed from a fluid or powder product dispensing device.
- counters are well known in the field of fluid product dispensers, in particular in the pharmaceutical field.
- these meters are used with dispensing devices of the MDI (Metered Dose Inhalers) type, in which a reservoir containing the fluid product and a propellant gas is mounted so as to be movable in a body, the displacement of the said reservoir causing the actuation of a metering valve mounted on said reservoir to dispense a dose of product, several constraints rest on said counter.
- MDI Metal Dose Inhalers
- the maximum stroke of the actuation of the meter must be less than the minimum stroke of actuation of the valve or of the pump, taking into account the manufacturing tolerances of the parts constituting the meter and the valve or pump.
- the problem which arises in this case is that this travel is generally very short and that the tolerances of the device tend to further reduce the distance effectively available for perform this action.
- This generally requires the use of a complex mechanism to provide functional and safe counting.
- the object of the present invention is to provide a dose counter for a fluid or powder product dispensing device which does not reproduce the aforementioned drawbacks.
- the object of the present invention is in particular to provide such a counter which guarantees actuation of the counter before the dose is dispensed, independently of the length of the actuation stroke of the pump or of the valve used in the device.
- the present invention also aims to provide such a counter which avoids any risk of under-counting.
- the present invention also aims to provide such a counter which avoids any risk of over-counting.
- the present invention also aims to provide such a counter which counts exactly the number of doses delivered, that is to say which counts exactly one dose at each actuation.
- Another object of the present invention is to provide such a counter which is simpler and therefore less expensive to manufacture and to assemble, and more reliable in operation.
- the present invention therefore relates to a dose counter for a fluid or powder product dispensing device, comprising an actuating element and at least a first counter element provided with a first set of teeth defining a plurality of recesses, said element actuation being axially movable along an axis X between a rest position and an actuation position, being elastically biased towards its rest position by an elastic element, such as a spring, said first counting element being rotatably mounted around a first axis of rotation A perpendicular to said axis X, said actuating element comprising two flexible lugs, a first flexible lug cooperating with said first toothing to cause said first counting element to rotate in a direction of counting when said actuating element moves from its rest position to its actuating position, and a second flexible lug cooperating with said first toothing to rotate said first counting element also in said counting direction when said actuation returns from its actuation position to its rest position, said first and second flexible lugs being arranged radially outside
- said abutment element guides said second flexible leg from an initial recess to an immediately adjacent recess, preventing said second flexible leg from passing directly into a non-adjacent recess, thus preventing an overcount.
- said abutment element is disposed radially inside and axially below said second flexible lug.
- said stop element is radially and axially inclined with respect to said axis of movement of said actuation element.
- said first and second flexible legs each comprise a free end in the form of a point or of a tooth, oriented in an opposite manner.
- said counter further comprises a second counting element provided with a second toothing, said first counting element comprising a first cam cooperating on each complete revolution of said first counting element with said second toothing to rotate said second counting element .
- a first indexing tab cooperates with said second toothing to define and maintain the position of said second counting element between two actuations.
- said counter further comprises a third counting element provided with a third toothing, said second counting element comprising a second cam cooperating on each complete revolution of said second counting element with said third toothing to rotate said third counting element .
- a second indexing tab cooperates with a fourth toothing of said third counting element to define and maintain the position of said third counting element between two actuations.
- said first counting element is a unit wheel, comprising first indicating means formed by the digits 0 to 9 and a first toothing comprising ten recesses adapted to cooperate with said first and second flexible lugs of said actuating element
- said second counting element is a tens wheel, comprising second indicating means formed by the digits 0 to 9 and a second toothing comprising ten recesses adapted to cooperate with said first cam of said first counting element
- said third counting is a hundreds wheel, comprising third indicating means, in particular formed by the digits 0 to 2, and a third toothing comprising in particular three recesses adapted to cooperate with said second cam of said second counting element.
- said counter comprises a cover provided with a viewing window.
- the present invention also relates to a fluid or powder product dispensing device comprising a reservoir, a dispensing member, such as a metering valve, mounted on said reservoir, and a body incorporating a dispensing orifice, said reservoir being movable axially in said body along an X axis to dispense the fluid or powder product, said device comprising a dose counter as described above.
- said counter is fixed laterally to said body, said device being actuated by manual axial pressure of the user on the reservoir and the actuation of said counter being achieved by said axial displacement of said reservoir which cooperates with said actuating element of said counter.
- a first part of the meter actuation cycle is carried out before any dispensing of fluid or powder product, and a second part of the meter actuation cycle is performed after dispensing of fluid or powder product.
- said first counting element rotates around a first axis of rotation A
- said second counting element rotates around a second axis of rotation B
- said third counting element rotates around a third axis of rotation C
- said axes of rotation A, B, C being perpendicular to said axis X of displacement of said tank

- a fluid dispenser device comprising a dose counter in exploded view which corresponds to a particular embodiment of the present invention.
- this implementation is only an example of realization and several elements could be realized in a different way.
- the device shown in Figure 1 comprises a body 10 provided with a mouthpiece 11 and comprising a hollow sleeve 12 receiving a reservoir 1 on which is mounted a metering valve 2 by means of a fixing ring 3.
- the reservoir 1 is axially movable along an X axis in said hollow sleeve between a rest position and an actuating position, and is elastically urged towards its rest position, generally by a return spring of said metering valve 2.
- the counter comprises at least a first counting element 30, cooperating with an actuating element 20.
- the actuating element 20 is axially movable in translation along an axis parallel to the axis X of displacement of the tank 1 between a rest position, visible in Figure 16, and an actuation position, visible in Figure 28.
- the first counting element 30 is rotatably mounted around a first axis of rotation A perpendicular to said axis X of the tank 1
- the actuating element 20 comprises drive means 21, 22 which convert the axial displacement of the actuating element 20 into a rotary displacement of the first counting element 30.
- the first counting element 30 is a units wheel, and the counter can advantageously further comprise a second counting element 40 forming a tens wheel.
- the counter can advantageously further comprise a second counting element 40 forming a tens wheel.
- the meter is mounted laterally relative to the body 10.
- the actuating element 20 comprises a projection 25 which is in contact with the tank 1 or an element integral with said tank 1, such as the fixing ring 3. During an axial displacement of said reservoir 1 in the hollow sleeve 12 of body 10, reservoir 1 moves this projection 25, which causes an axial displacement of said actuating element 20.
- the meter is assembled on the body 10, and a cover 180, provided with a viewing window 190, is provided to lock the assembly of the meter on the body 10.
- the body 10 comprises a stop element 19 cooperating with a movable part of the counter during actuation, as will be described in more detail below.
- the stop element 19 is formed by a radially and axially inclined projection relative to the axis of movement of the actuating element 20.
- the actuating element 20, shown in detail in Figures 7 and 8, comprises a base body 26 which supports two flexible legs 21, 22 forming the drive means.
- the base body 26 also supports the projection 25.
- the first and second flexible tabs 21, 22 each have a free end 23, 24, advantageously in the form of points or teeth oriented in an opposite manner.
- An axial lug 27 can be provided to receive a spring 5 adapted to elastically return the actuating element 20 from its actuating position to its rest position.
- the counter could include one or more elastic blades to perform this return spring function.
- the first counting element 30, shown in detail in FIGS. 9 and 10, comprises on one side first indicating means 31 intended to be visible through the viewing window 190 provided in the cover 180 of the counter, and the other side a first toothing 32 intended to cooperate with the flexible tabs 21, 22 of the actuating element 20.
- the first and second flexible tabs 21, 22 are arranged radially outside of said first toothing 32 and are biased radially inwards into contact with said first toothing 32.
- the first counting element 30 is a unit wheel, and the first indicating means 31 are therefore formed by the digits 0 to 9.
- the first toothing 32 comprises ten teeth defining ten adapted recesses to cooperate with the free ends 23, 24 of the two flexible lugs 21, 22.
- each tooth of the first toothing 32 comprises an abutment surface and an inclined surface which connects this abutment surface to the abutment surface of the tooth directly adjacent.
- the first counting element 30 comprises a central hole 35 which is inserted on a first stud of the body 10 forming the first axis of rotation A, so that the first counting element 30 rotates around said first axis of rotation A.
- the first counting element 30 When it is associated with a second counting element 40, the first counting element 30 comprises a first cam 33, which can be formed by a radial projection as seen in Figures 9 and 10, and which is adapted to cooperate with the second element of counting 40 at each complete revolution, therefore every ten actuations in the example of the figures.
- the first flexible lug 21 cooperates with said first toothing 32 of the first counter element 30 when the actuating element 20 is moved from its rest position to its actuating position. This has the consequence of causing said first counting element 30 to rotate in a counting direction.
- the second flexible lug 22 cooperates with said first toothing 32 of the first counting element 30 to cause said counting element 30 to rotate in this same counting direction when the actuating element 20 returns from its actuating position to its rest.
- the meter actuation cycle is separated into two distinct parts, a first part performed when the actuation element 20 is moved from its rest position to its actuation position and a second part which is performed when the actuating element returns from its actuating position to its rest position.
- the second counting element 40 comprises on one side second indicating means 41 intended to be visible through the display window 190 of the counter, and on the other side a second toothing 42 intended to cooperate with said first cam 33 of the first counter element 30 each time the first counter element 30 has made a complete turn.
- the second counting element 40 is a tens wheel, and the second indicating means 41 are therefore formed by the digits 0 to 9.
- the second toothing 42 comprises ten teeth defining ten adapted recesses to cooperate with said first cam 33.
- each tooth of the second set of teeth 42 comprises an abutment surface and an inclined surface which connects this abutment surface to the abutment surface of the directly adjacent tooth.
- the second counting element 40 comprises a central hole 45 which is inserted on a second stud of the body 10 forming a second axis of rotation B, parallel to the first axis of rotation A, so that the second counting element 40 rotates around said second axis of rotation B.
- the second counting element 40 comprises a second cam 43, which can be formed by a radial projection as seen in Figure 12, and which is adapted to cooperate with the third counting element 50 at each complete turn, therefore every ten actuations in the example of the figures.
- the second counting element 40 cooperates with a first indexing lug 16 which cooperates with the second toothing 42. This first indexing lug 16 is pivotally mounted on the body 10, as can be seen in particular in FIGS.
- the purpose of the first indexing lug 16 is in particular to maintain the position of the second counting element 40 between two actuations in order to guarantee a readable display in the viewing window 190. It can also act to prevent rotation of the second counting element. counter 40 in the direction opposite to that given to it by the first cam 33 of the first counter element 30.
- the third counter element 50 shown in detail in FIGS. 13 and 14, comprises on one side third indicating means 51 intended to be visible through the display window 190 of the counter, and on the other side a third toothing 52 intended to cooperate with said second cam 43 of the second counting element 40 each time the second counting element 40 has made a complete turn.
- the third counting element 50 is a hundreds wheel, and the third indicating means 51 are therefore formed by the numbers 0 to 2, for a counter suitable for counting 200 doses.
- the third toothing 52 has only a limited number of teeth defining recesses suitable for cooperating with said second cam 43.
- the third counting element only forms a wheel section, which is advantageous from the point of view of the size of the counter and therefore the size of the device, but this is only one advantageous embodiment.
- each tooth of the third set of teeth 52 comprises an abutment surface and an inclined surface which connects this abutment surface to the abutment surface of the directly adjacent tooth.
- the third counting element 50 comprises a central hole 55 which is inserted on a third stud of the body 10 forming a third axis of rotation C, parallel to the first and second axes of rotation A and B, so that the third counting element 50 rotates around said third axis of rotation C.
- the third counting element 50 further comprises a fourth toothing 56, which cooperates with a second indexing lug 17 pivotally mounted on the body 10, as can be seen in particular in Figures 20, 26 and 41.
- the purpose of the second indexing lug 17 is in particular to maintain the position of the third counting element 50 between two actuations in order to guarantee a readable display in the viewing window 190.
- FIGS. 15 to 41 illustrate a complete counter actuation cycle according to the advantageous embodiment shown in the drawings.
- the number 200 is displayed in the viewing window 190, and the actuation cycle which will be described is therefore the one which will cause the display of the counter to change from 200 to 199, i.e. i.e. a counter which displays the number of doses remaining to be dispensed and which will count from 200 to 0.
- the counter could count the number of doses dispensed, counting from 0 to 200.
- Figures 15 to 20 show the counter's rest position, before actuation.
- the actuating element 20 is in the rest position, and the free end 23 of the first flexible lug 21 is in a first recess 32a of the first toothing 32 of the first counting element 30.
- the free end 24 of the second flexible lug 22 is in another recess 32x of the first toothing 32 of the first counting element 30.
- the first cam 33 of the first counting element 30 is in a recess of the second toothing 42 of the second counting element 40
- the second cam 43 of the second counting element 40 is in a first recess of the third toothing 52 of the third counting element 50.
- the first indexing lug 16 is arranged in a respective recess of the second toothing 42 of the second counting element 40
- the second indexing lug 17 is arranged in a respective recess of the fourth toothing 56 of the third counting element 50.
- Figures 21 to 26 show the position of the counter during actuation. This position is that in which the valve 2 is actuated to dispense a dose of the fluid product contained in the reservoir 1, and it can be seen that the counter has already started to be actuated, before this dose dispensing.
- the user has moved the tank 1 axially in the body 10, which has caused the axial movement downwards of the actuating element 20 with respect to the body 10.
- the free end 23 of the first flexible tab 21 is pushed to the bottom of the first recess 32a of the first toothing 32 and causes the first counting element 30 around axis A in the counting direction.
- the free end 24 of the second flexible tab 22 emerges from the recess 32x, and the rotation of the first counting element 30 brings the following recess 32y facing said free end 24 of the second flexible tab 22.
- the first cam 33 which rotates with the first counting element 30 rotates the second counting element 40 in its respective counting direction, with the first indexing lug 16 which elastically deforms radially outwards to come out of its recess of the second toothing 42.
- the second cam 43 which rotates with the second counting element 40 rotates the third counting element 50 in its respective counting direction, with the second indexing lug 17 which deforms elastically radially outwards to come out of its recess of the fourth toothing 56.
- Figures 27 to 30 show the position of the counter at the end of the actuation stroke. This position is the one in which the actuating stroke of the reservoir 1 and therefore of the actuating element 20 is continued after the dose dispensing position. It should be noted that this position is not essential for the operation of the counter, for which the actuating stroke could stop in the dose dispensing position of FIGS. 21 to 26.
- the actuating element 20 therefore reaches in the actuating position, with the first flexible tab 21 still in the recess 32a of the first toothing.
- the second flexible tab 22 is blocked radially by the abutment element 19, which prevents it from deforming further radially inwards.
- the abutment element 19 is arranged radially inside and axially below said second flexible tab 22, in the position represented in FIG. the outside, with the lower surface of the free end 24 of the second flexible tab 22 which slides on the abutment element 19, while still being elastically biased radially inwards.
- This stop element 19 makes it possible to guarantee that the second flexible tab 2 will not position itself two recesses further away, namely the recess 32z in FIG. 30, which would have the consequence is over-counting, since the first counting element 30 would then rotate by two increments instead of just one.
- the free end 24 of the second flexible tab 22 is moved radially outside the first toothing 32 by the stop element 19, and it therefore cannot be positioned in the recess. 32z, while axially, it is at this recess 32z.
- the first and second indexing lugs 16, 17 return radially inwards to position themselves in a next recess of their respective toothings 42, 56.
- Figures 31 to 35 show the position of the counter during the return stroke. This position is that in which reservoir 1 and actuating element 20 return from their respective actuating positions to their respective rest positions.
- the actuating element 20 rises towards its rest position under the effect of the spring 5, with the first flexible tab 21, still in the recess 32a of the first toothing 32, which slightly rotates the first counting element 30 in the opposite direction to the counting direction. This is particularly visible also in FIG. 31, where we see that the number 9 of the first counting element 30 is no longer exactly aligned in the viewing window 190 as was the case in FIG. 27.
- the second flexible tab 22 rises by sliding on the abutment element 19, still being biased elastically radially inwards.
- the free end 24 of the second flexible tab 22 rises axially and moves radially inwards to position itself in the recess 32y, which is the one directly adjacent to the recess 32x in which it was at the beginning of the actuation cycle.
- Figures 36 to 41 show the position of the counter at the end of the return stroke. This position is that in which reservoir 1 and actuating element 20 have returned to their respective rest positions. It can be seen that the viewing window 190 shows the number 199, with therefore a dose which has been counted during this complete actuation cycle.
- the actuating element 20 is raised to its rest position under the effect of the spring 5, with the free end 23 of the first flexible tab 21 which has deformed radially on the first toothing 32 to snap into place in the second recess 32b directly adjacent to the first recess 32a.
- the second flexible leg 22 rises axially by pushing on the recess 32y, which continues the rotation of the first counting element 30 in the counting direction.
- the indexing lugs 16, 17 not only prevent the second and third counting elements 40,50 from rotating in the opposite direction to the counting direction, but they also act as centering elements to perfectly position and center the indicating means 41, 51 in the viewing window 190.
- An advantage of the present invention is that the first flexible lug 21 is always in contact with the first toothing 32 of the first counting element 30.
- the free end 32 of the first flexible lug 21 is in a recess of the first toothing 32.
- the counter will be actuated, therefore always before the dose of fluid or powdery product is dispensed, this which guarantees that there can be no undercounting.
- the second flexible tab 22 comes out of the first toothing 32 and is positioned facing the next recess, which guarantees complete dose counting, even in the event of an actuation stroke not complete for tank 1 .
- the counter could be made in a different way to that shown.
- the shapes and positions of the first and second flexible tabs 21, 22 could be different, provided that the first flexible tab 21 is adapted to move the first counting element 30 in rotation in a counting direction and that then the second flexible leg 22 is adapted to move the same first counting element 30 in rotation in the same direction.
- the shapes and positions of the first and second indexing lugs 16, 17 could be different. The same applies to the first, second and third counting elements 30, 40, 50.
