A collapsible container includes a floor member having first and second pairs of opposed edges, a first pair of opposing side walls each pivotably attached to the first pair of opposed edges of the base, where each of the first pair of opposing side walls have a pair of lateral edges and a latch member extending therefrom. Also included is a second pair of opposed side walls each pivotably attached to a corresponding one of the second pair of opposed edges of the base, each of the second pair of opposed side walls have a pair of opposed lateral flanges inwardly depending therefrom and formed integrally therewith. Each lateral flange has an inner surface with a latch receiving portion formed therein, the latch receiving portion includes at least one clip member which has a spring portion flexible between a first position and a second position for accepting the latch member. Thus, when the container is oriented in an assembled position, the clip receives a corresponding latch member, and wherein to move the container to an inwardly collapsed position from the assembled position, a force is exerted against an exterior surface of each of the first pair of opposed sidewalls, the force sufficient for the latch member to overcome the spring portion and be released from the clip member.

The reinforced double-wall knock-down bin according to claim 1 further comprising, said side-panel bottom extensions having removable female fastening means and said pallet-base having removable male fastening means which engage with said female fastening means to secure said side-panel to said pallet-base. 3. The reinforced double-wall knock-down bin according to claim 1 further comprising an inter-meshed corner at each interface between said side-panel and said end-panel, said corners are aligned so that the openings, on the horizontal surfaces of said side-panel and said end-panel are vertically concentric, wherein each corner having a corner post fabricated of a material selected from the group consisting of plastic, metal tubing and solid rod inserted vertically, from an underside bottom corner opening of said pallet-base is disposed within the openings of said side-panel and said end-panel extension members so as to secure the interconnected panel members, an underside pallet-base corner outer leg opening having a parallel key-slot access channel enabling insertion of an elongated long nose pliers to grab onto the bottom end of said corner post to extract said corner post to facilitate component replacement. 4. The reinforced double-wall knock-down bin according to claim 1 wherein said pallet-base having a pair of outer legs and a center leg, and opposing ends of said pallet-base having a horizontal tongue between each outer pallet-base leg and the center leg, said end-panel having a first set of horizontal grooves at the bottom forming a tongue-and-groove lock with the tongue. 5. The reinforced double-wall knock-down bin according to claim 4 wherein opposing ends of the outer legs and center leg of said pallet-base having horizontal openings on vertical adjacent walls in concentric alignment, said bin having a plurality of bottom end rods with each bottom end rod inserted into said horizontal openings on the outer legs and center leg with said bottom end rod having end fastening means disposed on each end said rod having a predetermined length to allow concealment of end fastening means within a profile of said pallet-base outer-wall. 6. The reinforced double-wall knock-down bin according to claim 5 further comprising a plurality of vertical gussets in vertical side walls of said pallet-base legs under said openings for insertion of said bottom end rod providing substantial reinforcement to said bottom end rod. 7. The reinforced double-wall knock-down bin according to claim 5 further comprising said end-panel having a second set of horizontal grooves, opposite said first set of grooves of said end-panel, whereby said bottom end rod is also allowed to pass horizontally through said second set of horizontal grooves of said end-panel thereby securing said end-panel to said pallet-base. 8. The reinforced double-wall knock-down bin according to claim 1 further comprising said end-panel having a top corner interconnecting end-panel and side-panel locking means, and said end-panel having a horizontal extension of predetermined length and size extending outwardly from a top end of said end-panel, said side-panel having a corresponding matching recess in a top corner of said side-panel to form a locking arrangement in combination of end-panel and side-panel when assembled. 9.
