Embodiment Construction

[0039] [39] The dose indicator A of the present invention is applicable to any type of fluid product dispensing device. However, the dose indicator A of the present invention applies in particular to nebulizer devices, and advantageously to nebulizer inhalation devices comprising a dose valve mounted on a container containing product and propellant gas.

[0040] [40] figure 1A dispensing device B for which the dose indicator A of the invention is particularly suitable is schematically shown. The dispensing device B comprises a body 50 and a reservoir 51 on which a dosing valve 52 is mounted. The actuation of the device B is obtained by the axial movement of the reservoir 51 inside the body 50 during the actuation stroke, which movement actuates the valve compression of said valve 52 , which causes the expulsion of a dose of product through the buccal orifice 55 . Of course, the invention also applies to other types of dispensing devices, especially nasal atomizers, or device...

Abstract

A dose indicator for indicating the number of doses that have been dispensed or that remain to be dispensed from a fluid dispenser device, the indicator being characterized in that it comprises an indicator body, a drive element, a rotary transmission element, a first rotary counter element, and a second rotary counter element, said first and second rotary counter elements being disposed side by side in a common plane and turning about parallel axes of rotation, said first and second counter elements co-operating to provide a common indication on each occasion the indicator is driven, said first rotary counter element being a disk having a top surface and a bottom surface, said top surface including first indicator means located close to the outer peripheral edge of said top surface, and said bottom surface including a first gear co-operating with a drive gear provided on said rotary transmission element, said first rotary counter element including a drive tooth adapted to co-operate on each complete revolution of said first rotary counter element with a second gear provided on said second rotary counter element.

Description

technical field [0001] [01] The present invention relates to dosage indicators, and fluid dispensing devices including such indicators. Background technique [0002] [02] In the field of fluid dispensing devices for dispensing multiple doses, and especially in the field of nebulizers, a number of systems for indicating the number of doses dispensed or remaining to be dispensed have been developed. [0003] [03] Most of these systems have several disadvantages. Therefore, they are generally known by a plurality of constituent components that cooperate with each other. Accordingly, these counters or indicators can become very complex, bulky, and therefore expensive to manufacture and assemble. Documents EP-1 386 630 and WO2005 / 079727 describe such complex systems. Furthermore, indicator systems often include elastically deformable elements for the actuation system. In some cases, these elements may deform after several actuations and then no longer ensure reliable operatio...
