具有出口阀的加压式再填充罐
摘要：
一种加压式再填充罐(5)，该罐包括组合物的储存器(31)，所述组合物包括推进剂和尼古丁或药学上能接受的衍生物或其盐。所述储存器(31)在20℃下处于大于400kPa的压力下。再填充出口阀(20)包括具有轴向孔(24)的管(6)，所述轴向孔在距所述储存器(31)最远的轴向端处敞开，以提供在轴向方向上排放所述组合物的出口。当没有施加外力时，由具有大于10N的弹簧力的第一弹性构件将所述管偏置到闭合位置，所述管(6)能克服所述第一弹性构件的作用而从该闭合位置移位到分配位置，以打开从所述储存器向所述出口的流动路径。
摘要（英）：

A pressurised refill canister containing a reservoir of composition including a propellant and a nicotine or a pharmaceutically acceptable derivative or salt thereof. The reservoir is at a pressure of greater than 400 kPa at 20° C. A refill outlet valve comprises a stem with an axial bore open at the axial end furthest from the reservoir to provide an outlet which discharges the composition in an axial direction. The stem is displaceable from a closed position to which it is biased by a first resilient member with a spring force of greater than 10N when no external force is applied to a dispensing position against the action of the first resilient member to open a flow path from the reservoir to the outlet.
