A counter having an actuating element (20) and a counting element (30) with toothing (32), the actuating element axially movable along an axis (X) between a rest position and an actuation position, the counting element mounted to rotate on an axis perpendicular to the axis (X). The actuating element has a first flexible tab (21) engaging the toothing to rotate the counting element in a counting direction when the actuating element moves into its actuation position, and a second flexible tab (22) engaging the toothing to rotate the counting element in the counting direction when the actuation element returns to its rest position. The first and second flexible tabs are resiliently biased radially inward into contact with the first toothing. The counter has a stop element (19) which engages the second flexible tab limiting radially inward movement thereof when the actuating element moves into and out of its actuation position.
A dose counter for a device for dispensing a fluid or powder product, comprising an actuation element and at least one first counting element provided with a first toothing defining a plurality of recesses, said actuation element being axially movable along an axis between a rest position and an actuation position, by being resiliently biased towards the rest position by a resilient element, said first counting element being mounted so as to rotate on a first axis of rotation perpendicular to said axis, said actuation element comprising two flexible tabs, a first flexible tab engaging with said first toothing to rotate said first counting element in a counting direction when said actuation element moves from the rest position to the actuation position, and a second flexible tab engaging with said first toothing to rotate said first counting element, also in said counting direction when said actuation element returns from the actuation position to the rest position, said first and second flexible tabs being disposed radially outside of said first toothing and being resiliently biased radially inward into contact with said first toothing, wherein said counter comprises a stop element engaging with said second flexible tab to limit its radial movement inward when said actuation element moves into and out of the actuation position.
