The invention relates to a threaded plug (10) with an outside diameter of 100 mm or more for large containers, especially large pallet containers with a capacity of, for example, 1000 l, intended for the transport of gassing or outgassing substances. In order to prevent the undesirable formation of internal pressure in the container, there is an aperture (16) with an outgassing device (24) in the middle of the disc-shaped top (12) of the threaded plug (10) which is designed in such a way that it is impossible for a higher vapour pressure than 0.3 bar to form in the gas phase above the fluid content. |
