Patent ID: 7793798

Claim:
A dose indicator (A) for a fluid dispenser device (B), said dose indicator being characterized in that it comprises a rotary counting wheel ( 10 ) that is displaceable in rotation, and a slide member ( 20 ) that is displaceable in translation, said rotary counting wheel including indicator means ( 15 ) for indicating the number of doses dispensed or the number of doses still to be dispensed, and cooperating with a display opening ( 25 ) provided in said slide member ( 20 ), said rotary counting wheel ( 10 ) including a hollow profile ( 18 ) co-operating with a projection ( 28 ) of said slide member ( 20 ), the shape of said hollow profile ( 18 ) being such that at least some rotations of said rotary counting wheel ( 10 ) causes said slide member ( 20 ) to be displaced in translation, thereby modifying the position of said slide member ( 20 ) relative to said counting wheel ( 10 ), and in that the dose indicator further comprises actuator means for displacing said rotary wheel, said actuator means comprising two flexible elements ( 32 , 33 ) of different flexibilities, the more flexible element ( 32 ) enabling said rotary counting wheel ( 10 ) to be rotated at a start of an actuation stroke of the actuator means, and the less flexible element ( 33 ) enabling said actuation stroke to be continued after said counting wheel ( 10 ) has been rotated.
