A utility model that combines cold retention, airtightness, and rigidity. The high sealing performance achieved by the newly structured lever mechanism is equivalent to that of higher-end models. Reduces cold air leaks and water leaks even when moving, and does not impair cold storage performance. The insulation material is urethane, which has both cold retention and light weight, making it easy to carry around at ports and deliver on ships.
