This Egg Holder Rack is a space-efficient refrigerator storage system designed to maximize egg capacity within a 270 mm refrigerator shelf clearance. Traditional egg cartons typically use a single circular cavity, which wastes significant space in order to accommodate eggs of different sizes. This design solves that issue with a bowl-shaped egg tray structure, allowing eggs to sit securely while minimizing unused space.

The rack features four double-stacked layers with 66 mm spacing per layer, providing a total capacity of up to 48 eggs. Each layer slides smoothly like a drawer, allowing quick access without disturbing the other trays. The 64 mm inter-layer spacing ensures that eggs of various sizes fit snugly and remain stable during storage.

The tiered structure makes it easy to organize eggs based on purchase date, freshness, or cooking status. For example, one tray can store fresh eggs while another can hold boiled eggs, helping maintain a clear and organized refrigerator layout.

This design is optimized for refrigerator use, providing high capacity while maintaining a compact footprint.
