Embodiment Construction

[0032] figure 1 A plug closure according to the prior art is shown with a sealing cap 11 arranged on a plug 10 . The plug 10 is provided with an external thread 12 for screwing into a neck of the plug, not shown in detail here. The plug 10 has a plug groove 13 with key engagement projections 15 formed on an inner wall 14 of the plug groove 13 and which are separated from one another by gaps 16 . The gap 16 is delimited in the circumferential direction of the plug 10 by a drive surface 17 for supporting a radial drive of a plug key, not shown in detail here, which is introduced into the plug groove 13, so that A screwing torque is transmitted to the bung plug 10 for screwing in or unscrewing the bung plug 10 .

[0033] as from figure 1 As can be seen in the figure, the key engagement projection 15 also delimits, by means of a concave inner surface 18, a receiving chamber 19 formed in the plug groove 13 for receiving the joint provided on the sealing cover 11. The body part ...
