For improving the venting behavior of containers with beverages containing carbon dioxide, a container finish (1) and a closure (11) is provided with a twin-start thread. The thread comprises in each case two threads (3, 13) which extend over an angle of 240.degree. to less than 360.degree., preferably 280.degree., and which are arranged so as to be displaced at 180.degree.. In this way, initial or first sections (5), in which the threads (3) overlap each other vertically, are formed on the outside surface (2) of the container finish (1), as well as second sections (6) in which, vertically, only one thread (3) is arranged. On the inside surface (12) of the closure (11), initial or first sections (15) are formed in which the threads (13) overlap each other vertically, as well as second sections (16) in which, vertically, only one thread (13) is arranged. In each of the sections (5, 6, 15, 16), at least one venting recess (4, 14) is arranged per thread, said venting recess interrupting the threads (3, 13).
