Protective Packaging Device With Stacked Cellular Cores

The packaging device is divided into multiple functional segments: an outer wrap, a first core with cells oriented in a first direction, a second core with cells oriented in a second direction perpendicular to the first direction, and a separator between them. This segmentation allows each segment to provide specific functions - the first core provides shock absorption in one direction while the second core provides lateral stability in the perpendicular direction, resolving the contradiction between shock absorption and lateral stability.

The packaging device uses a composite structure combining different core materials with distinct cellular orientations. The first core and second core are made of different materials or have different cell structures, creating a composite system where the first core absorbs shocks from one direction and the second core provides rigidity and stability from the perpendicular direction, simultaneously achieving both shock absorption and lateral stability.

The patent merges multiple protective functions into a single integrated packaging device. Instead of using separate shock-absorbing materials and separate stabilizing structures, the invention combines both functions into one device with a first core and second core integrated together through a separator, all enclosed in an outer wrap. This merging provides comprehensive protection (shock absorption + lateral stability) while maintaining a unified, manageable structure rather than multiple separate components.

The packaging device achieves multi-functionality by incorporating both shock absorption and lateral stability support within a single device. The first core provides shock absorption capability while the second core provides lateral stability, and both are integrated into one packaging unit that can be applied to protect vulnerable areas of products, eliminating the need for multiple separate protective devices.
