The locking cap uses precision ultrasonic welding technology from Dukane’s Ultrasonics Division for speed, accuracy, and precision manufacturing.
Dukane worked with Cap-N-Lock from the concept stage and provided feasibility studies, design assistance, tooling, and on-site support.
Cap-N-Lock produces the cap and two adapters which fit a wide range of the most common prescription bottles.
The locking cap components, molded by Henry Plastics, consist of eight injection molded parts made of lightweight, strong acrylonitrile-butadiene-styrene (ABS) plastic.
The locking cap unit is assembled from the bottom up with the locking mechanism (dial numbers included) dropped in first, followed by a tension plate and then the lower twist-on cap.
The lower housing ring is then ultrasonically welded to the main housing to complete the assembly.
Cap-N-Lock president Joseph Simpson said the locking cap has combination dials which create a barrier to entry for young children and teens.
