Method of detecting a potentially void inhaler can valve (30), which valve (30) is attached to a can (10) by a ferrule crimp (80), comprising the steps: placing the can (10) in a can jig (220) that is arranged to retain the can (10) at a predetermined measurement height with respect to a diameter measuring means (230), measuring the diameter of the ferrule crimp (80) at the predetermined height, and comparing the measured crimp diameter with a predefined interval of acceptance, and if the measured diameter is outside a predefined interval classifying the inhaler can valve (30) as potentially void. There is also provided a crimp diameter measuring device (200) comprising: a base (210), a diameter measuring means (230) supported by the base (210), and a can jig (220) supported by the base (210), the can jig (220) being arranged to retain a can (10) placed therein at a predetermined measurement height with respect to a diameter measuring means (230).
摘要:
Inhaler valve (30) comprising a gathering ring (70) comprised of a non-elastomeric polymer-material, wherein at least one annular section (110, 140, 160, 180) of the gathering ring (70) is formed to be deformable in the radial direction in order to absorb over compression of the ring outer periphery when crimping the valve (30) onto a container (20). There is also provided an inhaler container (10) with such an inhaler valve.
摘要:
The invention relates to testing apparatus (1) for testing a container (2) of a suspension of a substance (3). The substance may in particular, but not solely, comprise a pharmaceutical substance. The substance (3) is suspended in a propellant (4), which is under pressure. The container (2) itself comprises a body (5), which defines a chamber and has a valve stem (6), which extends from a head of the body. A metering chamber is selectively communicable, by means of the valve stem, with the atmosphere and the chamber (7). The valve stem providing via a L-shaped conduit, which extends between the free end and the side wall thereof the outlet of the container (2) through which metered doses of the substance are released from the container (2). The testing apparatus (1) includes a gallery (8) for communicating, in use, in a fluid-tight manner with the said valve stem and actuating means, in use, actuating the valve stem so as to discharge a metered dose of substance and/or propellant into the gallery, repeatedly if necessary, until the pressure within the gallery is substantially equalised with the pressure within the container (2). The testing apparatus further includes pressure-measuring means (9) in communication with said gallery to provide a measurement of the pressure therein and hence the pressure within the container (2).
