<p>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).</p> |
