Device for distributing a fluid product

Abstract

The invention relates to a device for distributing a fluid product, comprising a body (10) provided with a distribution opening (15), distribution means (50, 80) for distributing a dose of fluid product each time an operation occurs and a dose counter to indicate the number of doses distributed or remaining in the distributor, said counter comprising a first rotating counting element (127) provided with a first surface comprising first indication means (125), such as figures and provided with at least one first teething (128, 129), a second rotating counting element (227) provided with a second surface comprising second indication means (225), such as figures and provided with at least one second teething (228, 229), a mobile actuator element (160), movable between a first position and a second position, said actuator element comprising a projection (168) which cooperates with said first teething (128) of said first counting element (127) to turn said first counting element (127) when said actuator element (160) moves form the first position thereof to the second position said first counting element (127) comprising at least one deformable finger (1270) which can be moved between a deformed and a non-deformed position, which cooperates in the deformed position with said second teething (229) on said second counting element (227) in order to turn said second counting element (227), said body comprising a cam (325) for deforming the at least one deformable finger (1270) into the deformed position thereof.

Description

technical field [0001] The present invention relates to fluid product dispensing devices, and in particular to dry powder inhalers. Background technique [0002] Dry powder inhalers are well known in the art. It exists in different types. The first type of inhaler consists of a reservoir that receives multiple doses of powder, the inhaler is equipped with a metering device that allows a dose of powder to be separated from the reservoir with each actuation to take it to an exit channel for dispensing to the user. Another type of inhaler consists in packing doses of powder in separate reservoirs of predetermined doses, and then opening one of these reservoirs each time the inhaler is actuated. This implementation ensures good powder tightness, since each dose is not opened until the moment it is expelled. To implement these separate reservoirs, variants have been proposed, such as an elongated strip of blisters or blisters arranged on a circular rotating disk. Inhalers co...

Problems solved by technology

This has the disadvantage that it is difficult to manage the force applied to ensure full opening without risking opening the next reservoir, especially if the opening member should be actuated by suction

A common disadvantage of these counters is that either they are very bulky, thus also increasing the size of the inhaler itself, or the displays are very small and often difficult to read, especially for elderly people.
