DETAILED DESCRIPTION

(7) The invention is described in detail below with reference to the above figures in form and exemplary embodiments. In all figures, the same technical elements are marked with the same reference signs.

(8) FIG. 1 shows a lid 1 in accordance with the invention with four rigid connectors 122 allocated to one lateral edge 113 and four movable connectors 121 allocated to an opposite lateral edge 113. Furthermore, two hooks 14 are provided on each of two lateral edges 113. Two components 16 in the form of actuating elements 17 are attached to the upper side 111 of the lid plane 11. In each case, these act on two allocated movable connectors 121. The upper side 111 of the lid plane 11 is reinforced by a plurality of reinforcing ribs 15 parallel to the lateral edges 113 and forms a honeycomb-like, here rectangular, structure.

(9) FIG. 2a shows a section of the lid 1 of FIG. 1 and FIG. 2b shows a cut through such subregion. An actuating element 17 with a connector 12 can be seen. The connector 12 has a partially circumferential groove 123. When the actuating element 17 is moved in the direction of the arrow, the connector 12 moves back and forth in a manner correspondingly perpendicular to the lateral edge 113 of the lid plane 11. A certain amount of play between the guide 13 of the connector 12 and the connector 12 itself can compensate for a positioning error of the lid 1 or the connector 12, as the case may be, with respect to a receptacle 21 or aperture 22 in a lateral wall 24 of a container 2.

(10) FIG. 3 shows an assembly 162 consisting of the connector 12, the actuating element 17 and two springs 18 formed by the assembly 162 or the component 16, as the case may be. Furthermore, two mounting points 161 for additional springs are attached to the actuating element 17. Thereby, the additional spring not shown here can be attached between the leaf spring formed by the actuating element and the mounting point 161. Furthermore, the actuating element 17 has an additional pin 163 on its side turned away from the connectors 12. Such pin 163 can be connected to the lid 1 by means of an aperture in a reinforcing rib 15 and an aperture in the pin 163 through a seal 19. When the actuating element 17 or the connector 12, as the case may be, is moved with respect to the reinforcing rib 15, the seal 19 is broken.

(11) FIG. 4 shows a system consisting of a container 2 and a lid 1 in accordance with the invention. The lid 1 is hooked into the complementary receptacles by means of the rigid connectors 122 on a lateral wall 24 of the container 2, and can be inserted into the container 2 by means of a pivoting movement (arrow). After the lid 1 has been inserted, the movable connectors 121 are returned to the closed position 124 and the container 2 is thereby closed with the lid 1.

(12) FIG. 5 shows a cut through a container 2 shown in FIG. 4 with the lid 1 closed. Both the rigid connectors 122 and the movable connectors 121 prevent the lid 1 from moving perpendicular to the lid plane 11 with respect to the container 2. When the lid 1 or the lid plane 11, as the case may be, is loaded from its lower side 112, the grooves 123 in the connectors 12 interlock with the lateral walls 24 of the container 2.
