Reinforced Polygonal Container Blank with Integrated Corner Panels

The patent combines multiple reinforcing panels (corner panels and end panels) into a single integrated blank structure. The blank includes a bottom panel with corner panels and end panels all connected on one sheet, allowing them to be formed and reinforced simultaneously rather than as separate components. This merging reduces the number of separate parts while maintaining the necessary reinforcement for stacking strength.

The blank is segmented into distinct functional zones: a bottom panel, corner panels extending from the bottom panel, and end panels extending from the corner panels. Each segment is designed with specific fold lines and adhesive application zones to perform its reinforcement function independently while working together as an integrated structure. This segmentation allows complex reinforcement to be achieved through organized divisions on a single sheet.

The blank is pre-configured with all necessary fold lines, panel extensions, and adhesive application zones before the forming process. The corner panels and end panels are pre-positioned and pre-connected on the blank, so that during high-speed formation, the machine only needs to execute predefined folding and bonding operations. This preliminary arrangement of all reinforcement elements on a single sheet enables efficient manufacturing.

The forming process uses dynamic folding operations where panels are folded along predetermined fold lines to transform the flat blank into a three-dimensional reinforced structure. The corner panels and end panels are dynamically positioned and secured during the forming process, allowing the structure to adapt to the container shape while maintaining reinforcement integrity. This dynamic formation process enables complex reinforcement to be achieved through controlled movement rather than complex static assembly.
