    • This application discloses a dose counter device of the type for use on an aerosol dispensing assembly having an aerosol container and an actuator. The dose counter device is used for indicating the release of a dose of aerosol medication caused by the application of a force, in an axial direction, on the aerosol dispensing assembly. The dose counter device has a cap, a slider and a first counter ring. The cap is moved in a first direction along an axis of the container, which causes movement of the slider in a first linear direction laterally, relative to the axis of the container, as a function of the movement of the cap in the first direction. The first counter ring is rotated through a first arc in a first circumferential direction about the axis of the container, as a function of the movement of the slider in the first linear direction. The cap is then moved in a second opposite direction, which causes the slider to move in a second opposite linear direction, which in turn causes rotation of the first counter ring through a second arc in the first circumferential direction about the axis of the container A sum of the first and second arcs of movement of the first counter ring defines a circumferential extent of movement of the first counter ring relative to the cap that indicates a single dose of aerosol medication dispensed from the container.
    • 本申请公开了一种用于在具有气溶胶容器和致动器的气溶胶分配组件上使用的剂量计数装置。 剂量计数器装置用于指示通过在轴向上施加在气溶胶分配组件上的力引起的剂量的气溶胶药物的释放。 剂量计数装置具有帽,滑块和第一计数器环。 盖沿着容器的轴线沿第一方向移动,这导致滑块相对于容器的轴线在第一线性方向上相对于容器的轴线的移动,这是沿着第一方向的运动的函数。 随着滑块在第一直线方向的移动,第一计数器环围绕容器的轴线在第一圆周方向上旋转通过第一弧。 然后,盖沿第二相反方向移动,这导致滑块在第二相对的线性方向上移动,这又导致第一计数器环围绕容器A的轴线在第一圆周方向上旋转第二弧 第一计数器环的第一和第二运动弧的总和限定了第一计数器环相对于帽的周向运动范围,其指示从容器分配的单剂量的气溶胶药物。

    • An aerosol metering valve comprising: (a) a valve stem movable between a rest position and a firing position comprising: a body portion comprising a circumferential sealing surface (b) a valve body comprising: a body wall, and an internal chamber defined at least in part by the body wall; and (c) a metering gasket having an inner periphery defining an aperture, being disposed near the most interior end of the internal chamber and being configured to be able to form a transient, substantially fluid-tight face seal against the circumferential sealing surface of the valve stem, where at the rest position of the valve stem, the body portion of the valve stem is located within the internal chamber and as the valve stem is moved from its rest position towards its firing position the circumferential sealing surface of the valve stem contacts the metering gasket to form a face seal thereby closing a metering chamber and thereafter further movement of the valve stem towards its firing position causes the metering gasket to deflect while maintaining the seal with the circumferential sealing surface of the valve stem; and wherein the metering gasket in an unbiased configuration is an annular disc having a substantially planar form and where the valve is constructed and arranged such that the inner periphery of the metering gasket is urged out of said substantially planar form at the rest position of the valve stem, or wherein the metering gasket is pre-biased into a dished-shape.
