Problems solved by technology
The problem in this case is that the actuation stroke is generally very short, and the tolerances of the device tend to further shorten the distance available to achieve the actuation in an efficient manner.
In the usual manner, the assembly of counters, especially with a plurality of interlaced rotating parts, is complex and therefore not only costly but also a source of failure

Embodiment Construction
[0033]The counter of the present invention is suitable for use with any type of dispenser for fluid or powdered products, but it is particularly suitable for MDI-type dispensing devices (not shown), especially on the front side surface thereof. Such devices generally have a body with an oral mouthpiece defining a dispensing orifice. A container is fitted in said body, said container having a dosing valve mounted on its opening. The dosing valve cooperates inside said body with a discharge channel opening into the mouthpiece. When the user presses on the bottom of the container, it slides the container axially inside the body along the longitudinal axis of said body, causing actuation of the valve and expulsion of a dose of fluid product. The operation of such an MDI-type device is well known to those skilled in the art and therefore will not be described in detail here. A counter may be interposed between a front side surface of the body and a cover member having a window an...

The invention relates to a portion meter for counting the number of portions of a fluid or powder product that have been dispensed or that remain to be dispensed from a fluid product dispensing device, wherein said meter comprises a body (460), a rotary counting member assembled in said body (460) on a pin (461) defining the axis of rotation, said rotary counting member interacting with an actuation member (1430) for rotating said rotary counting member upon each actuation of said actuation member (1430), said actuation member (1430) including a means (14301) for attaching to the body (460) arranged on a first side of said pin (461) and a substantially rigid supporting portion (1436) arranged on the second side of said pin (461), wherein said supporting portion (14360) supports an actuation member (1435) such that upon each actuation, the actuation member (1435) is translatably moved, said supporting portion (1436) being connected to said attachment means (14301) by an elastically deformable portion (14341, 14342, 14343) surrounding said pin (461), said supporting portion (1436) extending towards said pin (461) in the form of a substantially rectilinear flexible arm (1431) supporting a lug (14310) capable of interacting with said counting member upon each actuation.
Description
technical field [0001] The present invention relates to counters, in particular dose counters for indicating to a user the number of doses dispensed or remaining to be dispensed from a fluid or powder dispensing device. Background technique [0002] The use of counters or indicators is well known in the field of fluid dispensers, especially in the pharmaceutical field. These counters or indicators are especially used in conjunction with dispensing devices of the MDI (Metered Dose Inhalers: Metered Dose Inhalers) type, in which a container containing a fluid product and a propellant gas is removably mounted in the body, said container The movement of causes the actuation of the dose valve mounted on the container to dispense a dose of product. A first type of counter considers fixing the counter on the bottom of the container, protruding from the body, on which the user presses to dispense a dose. However, counters of this type have the drawback of affecting the actuation o...
