"Plurality" in this application refers to two or more (including two).

A container is a group tool for loading and transporting goods, and is convenient for loading and unloading with mechanical equipment. Containers have formed a complete set of standardized systems. Container standardization can not only improve the versatility and interchangeability of containers as a common transport unit in sea, land and air transportation, but also improve the safety and economy of container transportation. Container standards are classified according to the scope of use, including international standards, national standards, regional standards and company standards. my country's current national standard "Container External Dimensions and Rated Weight" (GB1413-2008) stipulates the external dimensions, limit deviation and rated weight of various types of containers. Therefore, only by maximizing the internal space of the container while the external dimensions meet the national standard can more goods be loaded, thereby improving the space utilization rate of the container. At present, there are mainly two ways to increase the internal space of the container. On the one hand, under the premise of meeting the strength requirements of the container, the thickness of the bottom plate, top plate, and side plate is reduced, thereby increasing the length, width, and height of the internal space, and making the container volume larger. On the other hand, the assembly method of each component of the container is optimized to reduce unnecessary space occupation, thereby improving the space utilization rate of the container.

The container is equipped with end doors or side doors for easy loading and unloading of goods. The end door is arranged at the front end or the rear end of the container body, and the side door is arranged at the side of the container body.
