Dose indicator (A) for indicating the number of doses dispensed or remaining to be dispensed from a fluid product dispensing device (B), characterized in that it comprises an indicator body (100), an actuating element (1), a rotary transmission element (7), a first rotary counting element (13) and a second rotary counting element (10), said first and second rotary counting elements (13, 10) being positioned side by side in the same plane and rotating about parallel axes of rotation, said first and second counting elements (13, 10) collaborating to provide a common indication upon each actuation of the indicator, said first rotary counting element (13) being a disc having a top surface and an underside, said top surface comprising first indicator means positioned at the outer peripheral edge of said top surface and said underside comprising a first gear (16) collaborating with actuating gears (9) provided on said rotary transmission element (7), said first rotary counting element (13) comprising a drive tooth (15) able, upon each complete revolution of said first rotary counting element (13), to collaborate with a second gear (12) provided on said second rotary counting element (10).
摘要:
A counter for a fluid flow meter comprises a count display device, a driving means and mounting means for mounting the driving means and count display device to a housing of the fluid flow meter. The count display device indicates a volume of fluid having passed through the meter and has a window configured to seat sealingly in an aperture in the housing. The driving means drives the count display device and comprises a load-bearing frame having a gear train mounted thereto. The mounting means is configured to bias the counter toward the aperture to seal the window thereon, and to provide a biasing force to a portion of the load-bearing frame. The frame is configured such that the biasing force is prevented from affecting relative alignment of gears of the gear train.

The invention relates to a hand-held device (1) for the dosed distribution of sprayable substances, especially medicaments to be inhaled, said device comprising a cartridge (3) that can be displaced into the distribution-opening position by means of pressure in a housing (2), and a feeding mechanism (11) moved by the opening course of the cartridge (3) and used to register and display the distribution actuation carried out. Said feeding mechanism (11) is arranged in the centre of a housing (34) below the front wall of the cartridge (3), on the opening side, overlapping the cartridge valve tube (5). The aim of the invention is to provide one such hand-held device in a spatially favourable manner, with more reliability in terms of handling, and a simplified structure. To this end, a stepped feeding mechanism (11) arranged in a plate-shaped housing (34) is provided with control elements (S, 28, 29, 16, 17, 20, 15, 21, 22, 13, 26) which rotate about the axis located in the longitudinal direction of the cartridge (3).
