1. A container comprising: an enclosure housing an interior compartment for containing waste and further defining slots on sides of the enclosure for receiving lifting forks;a lockable rear lid pivotally connected to the enclosure; andan automatic unlocking mechanism actuated by lifting forks inserted into the slots for unlocking the rear lid to enable waste to be dumped from the container, wherein the automatic unlocking mechanism comprises:a curved pivot plate that pivots upwardly when displaced by a lifting fork;a main linkage arm pivotally connected to the curved pivot plate;a pivot arm pivotally connected to the main linkage arm;a locking hook connected to the pivot arm, the locking hook disengaging from an underside of the rear lid to unlock the rear lid;a first stopper for limiting upward movement of the curved pivot plate and a second stopper for limiting downward movement of the curved pivot plate; anda spring disposed between an upper surface of the curved pivot plate and the first stopper. 2. The container as claimed in claim 1 wherein the automatic unlocking mechanism relocks the lid when the lifting forks are retracted from the slots. 3. The container as claimed in claim 1 further comprising a lockable access hatch on a front face for inserting waste into the container. 4. The container as claimed in claim 1 wherein the automatic unlocking mechanism comprises a displaceable member extending into one of said slots, the displaceable member being displaced by the lifting fork inserted into said one of said slots. 5. The container as claimed in claim 4 wherein the displaceable member rotates from a first position within said one of said slots to a second position above the lifting fork when the lifting fork is inserted into said one of said slots. 6. The container as claimed in claim 1 wherein the slots are defined by substantially rectangular channels each having a top surface that includes a rectangular opening to permit the curved pivot plate to rotate upwardly. 7. The container as claimed in claim 6 further comprising guide plates extending from each slot to provide a flared mouth for guiding the lifting forks into the slots. 8. The container as claimed in claim 1 wherein the first stopper is an L-shaped stopper disposed at an angle relative to a top surface of one of said slots and wherein the second stopper is a lip for abutting an edge of a rectangular opening in the top surface of said one of said slots.
