Rapid prototyping or additive manufacture might, in future, be used not just for products but for innovative packaging.

Today’s invention is an example of this approach: a tamper-evident display container for eg an expensive chronometer.

The box would be built up of multiple layers of transparent goop, with the watch on the inside.

On completion, it would consist of two nested components: an inner with a wrist-like support for the watch strap and an outer wall.

The inner and outer would be prevented from rotating by two small cylindrical lock features.

On purchasing the watch, the outer wall would be rotated about the inner, snapping off the lock features and allowing the valuable contents to be extracted through the resulting gap.
