Respective coupling devices are movably fastened to two opposite side walls of the bottom part. In order to enable dimensionally stable and connected stacking of structurally identical system containers and also modular stacking of different system containers, each coupling device can be moved between an idle position, in which the coupling device is arranged below a top side of the lid part, and a coupling position, in which the coupling device projects beyond the top side of the lid part. ## Claims ### Claim 1 A stackable system container comprising: a bottom part; a lid fastened to the bottom part; and a first coupling device fastened movably to one side wall of the bottom part or lid, and a second coupling device fastened movably to an opposite side wall of the bottom part or lid, wherein each of the coupling devices is movable between a rest position, in which each of the coupling devices is arranged beneath the top of the lid, and a coupling position, in which each of the coupling devices protrudes beyond the top of the lid, wherein a locking element is movably fastened to at least one of the coupling devices for fixation of the at least one of the coupling devices, the locking element releasably locking the at least one of the coupling devices in the coupling position so as to prevent movement into the rest position, and wherein the locking element includes a hook-like element for releasably locking the at least one of the coupling devices in the coupling position. ### Claim 2 (depends on 1) The stackable system container according to claim 1, wherein each of the coupling devices has at least one coupling element for positioning and fixing an additional system container on the top of the lid. ### Claim 3 (depends on 2) The stackable system container according to claim 2, wherein, beneath each of the coupling devices, a counter element corresponding to the at least one coupling element is provided on the side wall for retentive cooperation with a corresponding coupling element of a coupling device of an additional system container arranged underneath. ### Claim 4 (depends on 1) The stackable system container according to claim 1, wherein each of the coupling devices is pivotably fastened to one of the side walls so as to be pivotable between the pivoted-in rest position and the pivoted-out coupling position. ### Claim 5 (depends on 4) The stackable system container according to claim 4, wherein each of the coupling devices can be pivoted around a pivot axis parallel to one of the side walls, and the pivot axis is arranged so that the locking element in the pivoted-in rest position is arranged beneath the pivot axis and in the pivoted-out coupling position above the pivot axis. ### Claim 6 (depends on 1) The stackable system container according to claim 1, wherein a spring element is arranged on each of the coupling devices that forces the locking element into a locking position that locks at least one of the coupling devices in the coupling position. ### Claim 7 (depends on 1) The stackable system container according to claim 1, wherein a snap-in tab is provided on each of the side walls that is engaged in a locking fashion by the corresponding locking element for locking at least one of the coupling devices in the coupling position. ### Claim 8 (depends on 1) The stackable system container according to claim 1, wherein each coupling device can be pivoted by 180° between the rest position and the coupling position. ### Claim 9 (depends on 1) The stackable system container according to claim 1, wherein the side walls each have a recess in which one of the coupling devices is movable into the rest position. ### Claim 10 (depends on 1) The stackable system container according to claim 1, wherein at least one snap-in device for locking of at least one of the coupling devices in the rest position is provided on each of the coupling devices. ### Claim 11 (depends on 10) The stackable system container according to claim 10, wherein the snap-in device can be overcome by exerting a sufficient torque on the at least one of the coupling devices. ### Claim 12 (depends on 10) The stackable system container according to claim 10, wherein the snap-in device can be overcome by activating a release lever. ### Claim 13 (depends on 1) The stackable system container according to claim 1, wherein the coupling devices lock the lid against opening in the coupling position. ### Claim 14 (depends on 1) The stackable system container according to claim 1, wherein the locking element releasably locks at least one of the coupling devices in the coupling position so as to prevent movement in any direction. ### Claim 15 (depends on 1) The stackable system container according to claim 1, wherein in the coupling position, the hook-like element engages a snap-in tab that is provided on the side wall, so that at least one of the coupling devices is releasably locked in the coupling position. ### Claim 16 (depends on 1) The stackable system container according to claim 1, wherein in the coupling position, the hook-like element must be disengaged from a snap-in tab, which is provided on the side wall, in order to move at least one of the coupling devices into the rest position. ### Claim 17 (depends on 1) The stackable system container according to claim 1, wherein each of the coupling devices can be pivoted around a pivot axis parallel to one of the side walls, the locking element releasably locking at least one of the coupling devices in the coupling position such that rotation of the at least one of the coupling devices around the pivot axis is prevented. ### Claim 18 (depends on 17) The stackable system container according to claim 17, wherein in the coupling position, the locking element must be released in order to rotate at least one of the coupling devices around the pivot axis into the rest position.
