A patent application (Publication Number: US20240017875A1) describes a flattenable volume-optimized container, preferably made of corrugated cardboard, with a prism-shaped layout. The container consists of at least eight connected sidewall parts, forming a ring, with two parallel sidewall parts of the same length. The design includes a bottom part alignable with the sidewall parts and foldable between them, with specific lengths for different sidewall parts. Additionally, folding lines on opposite sidewall parts allow the container to be flattened effectively, enhancing storage and transportation efficiency.

Furthermore, the container design includes variations in sidewall lengths, bottom part configurations, and tabs for improved functionality. Different combinations of long, medium, and short sidewall parts, along with corresponding bottom parts and tabs, contribute to the collapsible nature of the container. The strategic placement of folding lines and tabs ensures smooth unfolding and stability during use. These features aim to optimize space utilization while maintaining structural integrity, making the container suitable for various storage and shipping applications. Overall, the patent application outlines a detailed and innovative approach to creating a space-saving and practical container design using corrugated cardboard material.
