US Patent 12012268 Packaging with integrated paper spring

Packaging may include a base box having a cavity to receive a product, and a first paper spring extending from an interior of a first sidewall of the base box and a second paper spring extending from an opposing interior of a second sidewall of the base box. Each of the first and second paper springs may be formed from the same blank as the first sidewall. The first and second springs are flexible such that the cavity may accommodate products of different lengths, and may resiliently absorb vibrations or impact forces during shipping.
