Abstract
A dose indicator for a fluid dispenser, the dose indicator includes at a minimum a ledge that actuates the dose indicator as the fluid dispenser device begins an actuation stroke that in turn actuates the first one of two flexible elements of the dose indicator that begins the actuation of a rotary counting wheel at the start of the actuation stroke of the fluid dispenser device, and the second less flexible element continues the actuation of the rotary counting wheel after the actuation stroke of the fluid dispenser device is completed. In some embodiments, the rotary counting wheel interacts with a display window with a groove and pin system to both rotate and translate the display window.

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.
A dose indicator for a fluid dispenser device, wherein said dose indicator comprises a rotary wheel that is displaceable in rotation, the indicator further comprising actuator means for displacing said rotary wheel, said actuator means comprising two flexible elements of different flexibilities, the more flexible element enabling said rotary wheel to be rotated at a start of an actuation stroke of the actuator means, and the less flexible element enabling said actuation stroke to be continued after said rotary wheel has been rotated.
A dose indicator for a fluid dispenser device, wherein the dose indicator comprises:
- a rotary wheel that is displaceable in rotation;
- an actuator comprising a first flexible element and a second flexible element, wherein the first flexible element is more flexible than the second flexible element, the actuator further comprising a movable transmission element configured to engage a dispenser device;
- and
- wherein initial movement of the movable transmission element causes the first flexible element to flex and rotate the rotary wheel by a predetermined amount before the first flexible element is stopped and thereafter the second flexible element to flex so as to allow continued movement of the movable transmission element.
