A container device includes a skeleton having four vertical posts and four
lower and four upper beams to be secured between end portions of the
posts. Each of the posts includes a slot formed in one side and a groove
in the other side of each of the end portions. A number of corner
couplers each includes three extensions perpendicular to each other, for
engaging into open ends of the beams and the posts. A number of insert
panels are engaged into the end portions of the posts via the grooves of
the posts and each includes a screw hole. A number of fasteners are
engaged into the corner couplers, and threaded with the screw holes of
the insert panels to secure the corner couplers and the beams and the
posts together, and to form a parallelepiped container.
