A knock-down bin, formed from molded polymer materials, includes a rectangular base having a length L and a width W, two sides for deploying parallel to the length and a two sides for deploying parallel to the width. The sides meet to define four vertical corner portions. At least one corner portion, and preferably all four, include a hollow vertical 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, integrally formed with the other side making up the corner portion, projects through the lateral opening into the vertical channel. A locking element is slidingly deployable within each vertical channel between an unlocked position in which the projection can be inserted and removed from the lateral opening and a locked position in which the locking element engages the projection so as to lock it within the channel, thereby locking together the adjacent first and second sides.

[ What is claimed is:] [1.] A knock-down bin comprising:(a) a substantially rectangular base having a first dimension and a second dimension;(b) a first two sides each having a lower edge detachably engagable with said base for deployment parallel to said first dimension;(c) a second two sides each

[ What is claimed is:] [1.] A knock-down bin comprising:(a) a substantially rectangular base having a first dimension and a second dimension;(b) a first two sides each having a lower edge detachably engagable with said base for deployment parallel to said first dimension;(c) a second two sides each having a lower edge detachably engagable with said base for deployment parallel to said second dimension, such that said first two sides and said second two sides meet to define four vertical corner portions; and(d) at least one locking element deployable to lock together adjacent ones of said first two sides and said second two sides at at least one of said vertical corner portions, rein said at least one of said corner portions includes a hollow vertical corner post integrally formed with one of said first and second sides, said corner post having a vertical hollow channel and a lateral opening into said channel, said at least one of said corner portions also having a projection integrally formed with another of said first and second sides, said projection being configured to project through said lateral opening into said vertical channel of said corner post, said locking element being configured so as to be slidingly deployable within said vertical channel of said corner post between an unlocked position in which said projection can be inserted and removed from said lateral opening and a locked position in which said locking element engages said projection so as to lock said projection within said channel, thereby locking together said adjacent ones of said first and second sides.
