ABSTRACT:
The present invention relates to a composite packing container which generally comprises a bottom bracket, a front, rear, left and right side panels which jointly define a box unit, and a cover which can be enveloped onto the box unit. Characterized in that the front and rear side panels have an identical configuration and the side panel is configured by a multi-layer corrugated paper board having mounted with a L-shape iron plate by a locking screw at both ends. The upper and bottom sides of the paper board are enclosed with an U-shape bar which also covers to the L-shape iron plate. The left and right side panels are configured with an identical configuration and similar to the front and rear side panels in general. The left and right side panels are provided with a 7-shape iron plate which is different to the front and rear side panels. The 7-shape iron plate is designed and sized such that it can be readily received and retained within a space defined by the L-shape iron plate of the front and rear side panels. A locking screw is applied to lock them up.
