An improved box crate container comprises a base plate, two handle plates and two side plates. The handle and side plates pivot inwardly to collapse to the container by means of two release bars which are respectively located within two “T”shaped slots of the side plates. The two “T”shaped slots are respectively located on the upper corners of the side plates. With the side and handle plates upright, adjacent edges of the side and handle plates interlock by means of “T”shaped slots and hooked snap-fitting locking tabs which are formed respectively on the upper corners of the handle plates. The base, side and handle plates may be formed by single piece plastic injection molded. The side and handle plates are pivotally connected to the base plate by means of connecting blocks with two snap-fitting pivot axes and swivel recesses with two pivot tabs. The connecting blocks with the two snap-fitting pivot axes are formed on the lower portion of the side and handle plates. The swivel recesses with the two pivot tabs are formed on the periphery of the base plate. Every two pivot tabs are respectively located on the either side of each swivel recess. A pivot hole is formed on each pivot tab and passed through by the snap-fitting pivot axes.
