A knock-down bin, formed by polymer materials, includes a rectangular base (10) having a length L, and a width W, two sides (12) parallel to the length and two sides (14) parallel to the width. The sides meet to define four vertical corner portions. Each corner portion includes a hollow corner post integrally formed with one of the sides, the corner post having a vertical hollow channel into which a lateral opening opens. A projection (26) projects through the lateral opening into the vertical channel. A locking element (16) is slidingly deployable within each vertical channel between an unlocked position in which the projection can be inserted and removed from the lateral opening.
