Problems solved by technology

The problem in this case is that the actuation stroke is usually very short and the tolerances of the device tend to further reduce the distance available to achieve actuation in an efficient manner
In general, the assembly of counters, especially of counters comprising several rotating elements nested inside each other, is complex and therefore not only expensive but also a source of functional failures

Embodiment Construction

[0033] refer to figure 1 , figure 1A dispensing device 200 of the MDI type is shown, comprising on the front side a dose counter 100 corresponding to a particular embodiment of the invention. The dispensing device comprises a body 201 provided with an oral mouthpiece 202 defining a dispensing orifice 203 . A reservoir (not shown) is assembled in said body 201, said reservoir comprising a dosing valve mounted on its opening. The dosing valve cooperates within said body 201 with a discharge channel leading into the mouthpiece 202 . When the user presses on the bottom of the reservoir, it causes the reservoir to slide axially within the body 201, causing the valve to be actuated and a dose of fluid to be expelled. The operation of such MDI-type devices is well known to those skilled in the art and therefore will not be described in detail here. The counter 100 may be interposed between the front side of the body 201 and a cover member 250 which includes a window 251 and may b...

Abstract

A dose counter (100) for counting the number of doses of fluid or powder that have been dispensed or that remain to be dispensed from a fluid dispenser device (200), said counter including a first rotary counter element forming a units wheel, and a second rotary counter element forming a tens wheel, said first and second counter elements co-operating with each other to define and to display, in a viewing window (151), said number of doses, said first counter element co-operating with an actuator member that is adapted to cause said first counter element to turn each time said actuator member is actuated, said counter including a base body that incorporates a pivot pin for said first and second counter elements and an opening, said counter possibly being pre-assembled in said base body so as to form a pre-assembled counter unit.

Description

technical field [0001] The present invention relates to counters, and more particularly to dose counters for indicating to a user the number of doses dispensed or the number of doses remaining to be dispensed from a dispensing device for a fluid or powder product. Background technique [0002] The use of counters or indicators is well known in the field of fluid dispensers, especially in the field of medicine. These counters or indicators are used in particular with dispensing devices of the MDI ("Metered Dose Inhalers", metered dose inhalers) type, in which a reservoir containing a fluid product and a propellant gas is removably mounted in the body, Movement of the reservoir causes actuation of a dose valve mounted on the reservoir to dispense a dose of product. Counters of the first type are arranged such that the counter is fixed on a bottom of the reservoir protruding from the body, on which the user presses to dispense a dose. However, this type of counter has the dis...
