ABSTRACT:
A device to indicate the application of a non-rotative force, having particular utility in recording the dispensing of a push-down activated aerosol medication dispenser. A non-rotative force on an outer cover is translated into a rotation of an indicator wheel relative to the outer cover by a set of flexible pawls engaged with a set of teeth. The pawls depress and thereby extend circumferentially when the applied force flexes them to effect a rotation of the teeth. Suitable means indicate the relative rotation of the teeth such as a window in the outer cover through which is visible indicia on the indicator wheel. The device may also include means to resist its operation by a child.
