A container guiding device has a railing with two guide elements that are spaced from one another, that extend in the transport direction of a container transport device, and that guide containers or packages. At least one guide element can be adjusted transversely to the transport direction relative to the other guide element by an adjusting device. The adjusting device has a drive body which can be rotated about a rotational axis and a coupling element which is connected to the at least one guide element and to the drive body such that a rotation of the drive body produces a translation of the coupling element transversely to the transport direction. The drive body has a control element which is in engagement with the coupling element and which runs in a spiral shape about the rotational axis of the drive body, at least along some sections.
