The invention claimed is: 1. A reusable container comprising a container bottom and side walls that are attached thereto in an articulated manner and can be folded down in the direction of the container bottom, so that the side walls can be folded down onto the container bottom for transport and storage when the container is empty and locked to each other when they are in the upright position, wherein interlock devices on at least one side wall comprise a pressure lever that can be folded down in a direction towards the container bottom, the pressure lever being provided with a locking hook that, when the side walls are in the upright position, overlaps with a locking hook of a locking catch on the side wall adjacent to the at least one side wall in order to interlock the side walls, wherein the locking catch in the side wall includes spring-like elastic characteristics and locking protuberance that projects inwards from an interior face of the adjacent side wall as to assure that the locking catch will build up an elastic return force when it is pressed outwards due to rotation of the pressure lever. 2. A container in accordance with claim 1, wherein the pressure lever is provided with a gripping part including a tongue having an inner edge that acts as a releasing edge that makes contact with a part of the adjacent side wall that is set back with respect to the locking protuberance of the locking catch. 3. A container in accordance with claim 2, wherein the locking catch includes a locking strip. 4. A container in accordance with claim 3, wherein the locking catch includes a lead-in ramp that runs obliquely inwards. 5. A container in accordance with claim 4, wherein the lead-in ramp connects with the locking strip and/or the locking protuberance. 6. A container in accordance with claim 3, wherein the locking catch is provided at its free end with a section that is set back with respect to the locking strip and/or the locking protuberance. 7. A container in accordance with claim 6, wherein the free end of the locking catch is designed as a hook. 8. A container in accordance with claim 2, wherein the pressure lever is joined to the side wall in an articulated manner by means of two narrow webs. 9. A container in accordance with claim 8, characterized in that a tongue of the pressure lever extends between the narrow webs. 10. A container in accordance with claim 8, wherein the webs on the side wall define an articulation point that constitutes a center of rotation of the pressure lever. 11. A container in accordance with claim 10, wherein the articulation point comprises a dome-shaped pressing part. 12. A container in accordance with claim 2, wherein the inner edge protrudes inwards as compared with the pressure lever and the tongue. 13. A container in accordance with claim 2, wherein the releasing edge is constituted by the free end of a web that projects in a substantially orthogonal direction. 14. A container in accordance with claim 1, wherein the locking catch comprises a resilient tongue within an opening of the side wall and with its edges delimits a narrow slot between it and the side wall on both sides. 15. A container in accordance with claim 1, wherein the locking catch has its spring-like elastic characteristics determined by a length of the tongue, thickness of the tongue, a width of the tongue and/or a thickness of an articulation point between the tongue and the side wall. 16. A container in accordance with claim 1, characterized in that a spring force of the locking catch is matched with the pressure lever in such a manner that when the pressure lever is rotated, the locking catch will be pressed outward to release an interlock of the locking catch and the pressure lever. 17. A container in accordance with claim 1, characterized in that a free end of the pressure lever comprises locking catch that engages with the locking hook and the locking catch in an upright position. 18. A container in accordance with claim 1, wherein a front edge of the locking catch is designed with a back taper for interlocking with a protruding edge of the pressure lever. 19. A container in accordance with claim 18, wherein the back taper tapers at an angle between 3�� and 20�� and that an edge of the pressure lever with which it interlocks is designed with a complementary oblique face. 20. A container in accordance with claim 19, wherein the back taper tapers at an angle of between 5�� and 15��.
