The container proposed also meets the requirements for ease of recycling by virtue of the fact that only a single material is use in its construction.

Abstract: A foldable fence for confining babies includes a plurality of first supporting means, second supporting means, folding means, multiple tubes and supporting rods. The tubes each further have a mid-section with an eccentric member enclosed therein, so that when using the mid-section to extend the length of the tube is completed, turning the tube will make the eccentric member abut a peripheral side wall of the tube and therefore the length of the tube is fixed. The second supporting means provides a clearance for a rivet to move back and forth, so that when the second means abuts against a surface, such as a wall, a resilient member will provide a resilient force to further stabilize the abutting to the wall. The folding means connected between two supporting rods provides a folding mechanism to the foldable fence constructed in accordance with the present invention, such that the foldable fence is folded together to minimize the size when the use of the fence is finished.
