Embodiment Construction

[0047] [47] Referring to Figure 1, there is shown in exploded view a dose indicator or counter corresponding to a particular embodiment of the present invention. Of course, this application is only one example, and the various elements of the indicator can be implemented in different ways. More precisely, the invention relates to the actuating means capable of actuating said counter, and of course the indicating means can be of any type and is not limited to the one shown in the figures.

[0048] [48] ​​More precisely, the indicator according to the invention comprises at least a metering element 5 , an actuating element 1 , and a driving element 6 . The actuating element 1 is movable axially, preferably in translation, and the metering element 5 is mounted rotatably around said axis of movement of the actuating element 1 . A drive element 6 is provided to convert the axial movement of the actuating element 1 into a rotational movement of the metering element 5 .

Abstract

The invention relates to an indicator for a device for dispensing a liquid or powdery product, said indicator comprising an actuating element (1) that can be axially displaced between an idle position and an actuating position, a rotatable counting element (5), and a driving element (6). According to the invention, the driving element (6) transforms an axial displacement of the actuating element into a rotary displacement of the counting element (5), the counting element (5) comprising teeth (9) which co-operate with elastic means (7, 8) of the driving element (6). Said elastic means (7, 8) are provided with at least two flexible tabs (7, 8), at least one first flexible tab (7) co-operating with the teeth (9) of the counting element (5) in order to rotate the counting element (5) in a counting direction when the actuating element (1) is displaced from the idle position thereof towards the actuating position thereof, and at least one second flexible tab (8) co-operating with the teeth (9) of the counting element (5) in order to rotate the counting element in the same counting direction when the actuating element (1) returns from the actuating position thereof to the idle position thereof.

Description

technical field [0001] [01] The present invention relates to an indicator, in particular a dose indicator, for indicating to a user the number of doses which have been or are to be dispensed from a fluid or powder product dispensing device. Background technique [0002] [02] Usage counters or indicators are well known in the field of fluid product dispensers, especially in the pharmaceutical field. Especially when these counters or indicators are used together with dispensing devices of the MDI (Metered Dose Inhalers: Metered Inhalers) type, limitations are imposed on said indicators in which a fluid product and a A reservoir of propellant gas is movably mounted in a body, movement of said reservoir causing a dosing valve mounted on said reservoir to actuate to dispense a dose of product. On the one hand, in order to avoid any risk of under-metering, it is generally required that the actuation of the counter be effected before or at the beginning of the stroke of the valve ...
