Devices and methods for verifying capping of vials in system for dispensing prescriptions

A method of verifying the seating and securing of a twist-on closure on a container, comprising the steps of:

• (a) positioning a container on a stage of an automated capping station;
• (b) bringing a twist-on closure into contact with the container;
• (c) detecting the height of the closure as it rests on the container;
• (d) responsive to step (c), relatively rotating the closure and the container if step (c) indicates seating of the closure on the container is proper;
• and
• (e) detecting the nature of a physical relationship between the closure and the container to determine whether the closure is properly secured.
