<p>A device (210) to indicate the application of a non-rotative force, having particular utility in recording the dispensing of a push-down activated aerosol medication dispenser (214). A non-rotative force on an outer cover (220) is translated into a rotation of an indicator wheel (250) relative to the outer cover by a set of flexible pawls (280) engaged with a set of teeth (260). The pawls depress and thereby extend circumferentially when the applied force flexes them to effect a rotation of the teeth. Suitable means to indicate the relative rotation of the teeth such as a window (226) in the outer cover through which are visible indicia on the indicator wheel. The device may also include lugs and cutouts (221, 233) to resist its operation by a child, a reset mechanism (461) and time and dosage indicia (579, 589 and 526).</p> |
