Apparatus and method for measuring alignment of metered dose inhaler valves

Abstract

An apparatus for measuring the alignment of a valve sealed onto a canister comprises hollow lower and upper sections, a mounting platform, and a transducer. The upper and lower interior regions cooperatively define an inner chamber in which the mounting platform is disposed. The transducer is mounted to the upper section and includes a probe extending through the upper section and into the inner chamber. The apparatus is adapted for relative rotational movement between the mounting platform and the upper section. The transducer is responsive to linear translation of the probe and displays a human-readable indication of the alignment of a valve sealed in a canister as the probe moves around the circumference of the top surface of the valve.
