A forcing-off device of an, in particular, explosion-proof or flameproof container for electronic devices, the container including at least one base body having an opening surrounded by an opening edge and a cover part that can be placed onto or inserted into the opening edge. A forcing-off shoulder is formed on the base body or cover part at least in a section in circumferential direction of the container. The forcing-off shoulder is part of a shoulder running around the opening edge, and at least one forcing-off part is rotatably mounted in a lateral recess of the cover part or on the base body in an eccentric fashion between a forcing-off position and a passive position. The forcing-off part is an eccentric disc and in the forcing-off position is in abutment with the forcing-off shoulder for the gap-forming spacing of cover part and base body.
