A detailed description of this detachable container will be provided as follows by referring to FIGS. 1A-1C.
A detachable container 100 comprises a base 110, side panels 120, corner posts 130 and a roof panel 140. The base 110 is used to support the cargo placed within the detachable container 100, and therefore, it needs to possess enough strength. The side panels 120 are detachably connected to the base 110 and to the roof panel 140 to form a space for accommodating cargo. In addition, the corner posts 130 are arranged between adjacent side panels 120, that is, the corner posts 130 are vertically arranged around the corner of the side walls of the detachable container 100 to connect adjacent side panels 120. Each of the side panels 120 is detachably connected to the corner posts 130. Wherein, a detachable connection, such as socket connection, threaded connection, clamping, etc., can be employed for connection between the side panels 120 and the base 110, between the side panels 120 and the roof panel 140, as well as between the side panels 120 and the corner posts 130. Also, an assisting connection device may be employed to achieve detachable connection. The present application will provide a preferable detachable connection which will be described in detail later in this disclosure. Because of the employment of the detachable connection between the side panels 120 and the base 110, the corner posts 130 and the roof panel 140, in the process of returning empty containers, these containers can be detached and folded into a whole piece, so as to reduce the occupation space.
According to an embodiment of the present invention, the roof panel 140 comprises a roof plate 141 and a skirt 142. The roof panel 141 can be of a plate-like structure or other similar structure, for covering onto the side panels 120 to form a relatively closed space for containing cargo. The skirt 142 is arranged around the periphery of the roof plate 141 and extends downwards, so as to form a cavity (not indicated) in the roof panel 140. This cavity is located under the roof plate 141 and surrounded by the skirt 142, for accommodating components including the side panels 120 and the corner posts 130 within this cavity after the detachable container 100 is detached. Furthermore, the dimensions of the side panels 120 are smaller than that of the roof panel 140 such that they can be accommodated within this cavity in a detached state. Since the dimensions of the side panels 120 are smaller than that of the roof panel 140 and a space for accommodating the side panels 120 is formed in the roof panel 140, in a detached state, the base 110 and the roof panel 140 can be used to pack the side panels 120 and the corner posts 130 therein (as shown in FIGS. 1B and 1C). The integrating of the detached components in a whole piece with a regular shape not only can avoid loss of detached components, but also can make the carrying and stacking of detached containers more convenient. As the dimensions of the side panels 120 are smaller than that of the roof panel 140, in order to ensure the enclosure of the detachable container 100, preferably, the cross section of each of the corner posts 130 is L-shaped, and the two edges of the L shape are connected to adjacent side panels 120, respectively.
In consideration of such factors as transportation efficiency and detaching convenience, the present invention provides a connector that can be detached fast, for connecting the side panels 120 and the base 110, the side panels 120 and the roof panel 140, as well as the side panels 120 and the corner posts 130. The detachable container 100 further comprises a base connector, a roof panel connector and a side panel connector, wherein the base connector connects the side panels 120 detachably to the base 110, the roof panel connector connects the side panels 120 detachably to the roof panel 140, and the side panel connector connects the side panels 120 detachably to the corner posts 130. A detailed description of these connectors will be provided as follows by referring to FIGS. 2A-2B, 3A-3B and 4A-4B.
