A sampling container for receiving media from a container filling system includes a closed base region, a peripheral wall adjoining the base region and extending substantially orthogonal to the base region, and a filling region opposite the base region and adjoining the peripheral wall. The filling region has a container neck extending substantially orthogonal to the base region and includes a filling opening. An outer thread is arranged over an outer periphery of the container neck. The thread has an outer diameter between 44 and 46 mm and a core diameter between 41 and 43 mm, and rounded edges, at least over portions, with a radius between 0.95 and 1.05 mm. The container neck can be arranged in a receiver of a sampling head, during the sampling process so that the container is sealed in a media-tight manner in relation to an ambient environment.
