  • Patent number: 9278802
    Abstract: The present invention discloses a detachable container comprising a base, side panels, corner posts and a roof panel, wherein the side panels are detachably connected to the base and to the roof panel, the corner posts are located between adjacent side panels and the side panels are detachably connected to the corner posts, respectively. A connection is employed for connecting the side panels with the base, the corner posts and the roof panel of the detachable container according to the present invention. Therefore, in the process of returning empty containers, each of the containers can be detached and form a whole piece, so as to reduce the space occupied. In addition, a modularized design may be employed for each component of the detachable container, so as to achieve universality of components of the container. Furthermore, this detachable container also has the advantages of convenient assembly, simple structure, etc.
