Abstract

A container comprises a container body and end doors for sealing end portions of the container body. The end doors are in a double-layer door structure and comprise two outer end doors located at an outer layer and an inner end door located at an inner layer. The two outer end doors are in the structure that the outer side ends of the two outer end doors are hinged to the container body and middle portions of the two outer end doors are opened oppositely. The inner end door is in an integral structure that one side end of the inner end door is hinged to the container body and the other side end of the inner end door can be opened towards the inside of the container body. According to the container, the end doors are in the double-layer door structure, the integral single door capable of being opened towards the inside of the container body is located at the inner layer, and the larger the bearing force stressed by the door is, the higher the sealing performance is, so leakage problems of bulkload can be effectively avoided, and safety risks in the aspect are eliminated.
