Technical Field
[0001] The utility model relates to the technical field of cartons, in particular to a carton with a magnetic opening and closing structure. Background Art
[0002] Cardboard, a common packaging material, is lightweight, cost-effective, and recyclable, making it an ideal packaging choice for a wide range of goods. Magnetic closures utilize magnetic plates and blocks installed on the hinges or edges of the lid to automatically attach and secure the lid. No additional closing materials or tools are required; simply close the lid to secure it.
[0003] However, existing cartons with magnetic opening and closing structures on the market are prone to loosening, resulting in a high risk of accidental opening. This situation mainly occurs for two reasons: first, the magnetic force of the magnetic sheets and blocks is not strong enough to withstand external impact or cargo shaking, resulting in loose closure; second, there is no additional locking device, and the closure is maintained solely by magnetic force, which makes it easy for vibration and collision to loosen during transportation and handling.
[0004] Therefore, there is an urgent need for a carton with a magnetic opening and closing structure to solve the above-mentioned technical defects. Utility Model Content
[0005] The purpose of the present invention is to provide a carton with a magnetic opening and closing structure to solve the problem of easy loosening and accidental opening of the carton proposed in the above background technology.
