摘要:
A source of a gaseous substance, an inner subassembly and an outer subassembly having an outer enclosure comprising, a counter (20) accommodated within the outer enclosure (11) for counting substance release displacements of the spout (4); and a counter actuation member arranged beside the spout (4) for displacement inwards to increment the counter (20), the outer subassembly having an overall length from the actuation member at the spout (4) to a pressurised-container reaction surface, which length decreases on substance release and having at least a first quiescent length and a second length at which counter incrementation is initiated, • the subassembly also having a tolerance adjusted connection of the cap (105) to the outer enclosure (11) set with respect to a use installation of the source, whereby the stroke between the first and second lengths of the respective subassemblies is compensated for synchronisation of substance release and count incrementation.
摘要:
A counter for a flow meter is disclosed. The counter comprises a liquid fillable and sealable housing containing at least one rotatable counter wheel. The counter wheel has at least one and preferably three apertures for allowing gas bubbles in the housing to move away from the wheel when the housing is filled with liquid. The apertures are preferably offset from the wheel's centre.

The invention relates to a dose counter for a device for dispensing a fluid product, comprising a first rotary counting element (410) forming the single units wheel and a second rotary counting element (420) forming the tens wheel. The first counting element (410) engages with an actuator member (430) designed to turn the first counting element (410) every time the actuator member (430) is actuated. In addition, the first rotary counting element (420) includes a means (418, 419) for turning the second counting element (420) every ten times the actuator member (430) is actuated. The actuator member (430) includes an opening rotatably mounted on the rotation shaft (461), with a substantially rigid and straight tab (431) extending radially from said opening, which tab (431) engages with the first counting element (410) with every actuation. The tab (431) extends away from the other side of the rotation shaft in the form of a substantially rigid and straight portion which is in turn connected to a curved, elastically deformable portion (434) that at least partially surrounds the rotation shaft (461).

The present invention relates to a metered dose inhaler dose counter, the counter comprising: an actuator; a rotary gear wheel having a plurality of ratchet teeth; a driver for driving the rotary gear in a step-wise fashion in response to displacement of the actuator; a pawl that prevents reverse rotation of the rotary gear; and a display coupled to the rotary gear.
