Rondo's Tamper-Evident Folding Box

I first came across Rondo's novel approach to providing tamper-evident tuck in carton flaps when featured early this year online at HealthCare Packaging. My curiosity was aroused but at that time I could not be sure how it worked because of the lack of clarity in the report and photo.

The same tamper-evident system was featured again in HealthCare Packaging on 1 May; this time a video was included. My interest was again aroused but, whilst the video included with the article showed a machine locking the carton's tuck in end, the detail was tantalisingly obscured and I still could not be sure of the precise modus operandi of the system.

A Packworld article, dated 25 July, also featured Rondo's tamper-evident system and provided the following description:

The folding box's first opening is easily detectable through perforations in the lid and dust flaps that rip off upon opening. This solution helps simplify the manufacturing process, while providing end-users with assurance and comfort. The new folding box brings a tamper-evidence solution said to be far less fallible than those using certain glue or labels. Apart from its user functionality advantages, the folding box has the added bonus of permitting machine speed to be maintained, helping to optimize OEE of the packaging line.

Again, the accompanying illustration left me unsure how the tear-off sections were locked into place. However, this time I was motivated to learn more and so I checked the manufacturer's website and found this video. Now we can all see how the two extremities of the carton end are inserted into dust flaps. They are cut to a shape similar to the spade used by turf cutters on the Irish peat bogs. The result is that when the carton end flap is opened, the perforation tears leaving behind two small spade-shaped pieces retained by the dust flaps.

Rondo-Pak Inc. has a nice webpage that describes the features of this tamper-evident system. Two of the highlights are that tamper-evident labels are not required and packaging machine speed is not affected by introduction of this system.

I have not seen this or a similar system in use. Has anyone purchased an item where the packaging has a similar tamper-evident system?
