The invention relates to a device and a method for filling or packing contents, particularly beverages, food, medications, or the like, into containers. As the containers pass through the device from an inlet to an outlet side, the containers passing through the working chamber have a sterile fluid, particularly sterile air, applied thereto for preventing germ growth. In order to reduce the cleaning effort for lines for the sterile fluid, the invention proposes that a cleaning medium having an internal line is inserted into the line for applying the sterile fluid. The line no longer needs to be disassembled in order to load the sterile fluid. In order to distribute the sterile fluid uniformly throughout the containers in a working chamber, the sterile fluid is distributed in two stages, first by means of the pipe extending into the working chamber, as described above and then through a profile extending over the containers and below the pipe, having openings for passing the sterile fluid. The profiles can be disposed rotatably about an axis, in order to reduce the cleaning effort after filling.

1. A device with a working space through which containers are conveyed from an entrance side to an exit side, comprising: at least one station in said working space to execute a work step on the containers;an external line passing through the working space, the external line configured for connection to a sterile fluid supply and the external line having several openings into the working space for the introduction of a sterile fluid from the sterile fluid supply into the working space to create a sterile atmosphere in the working space; andan internal line passing through the external line, the internal line being configured for connection to a cleaning medium supply that is different from the sterile fluid supply, and the internal line having several openings for spraying a cleaning medium from the cleaning medium supply into a space that extends longitudinally between the internal line and the external line. 2. The device according to claim 1, wherein the external and internal lines are pipes and are arranged so that the external and internal lines are rotatable around their longitudinal axes relative to each other. 3. The device according to claim 1, further comprising at least one profile provided with openings and extending over the containers, the at least one profile being arranged in the working space underneath the external line, the at least one profile distributing over the containers in the working space the sterile fluid introduced through the external line. 4. The device according to claim 3, each the at least one profile is rotatable around an axis between a first position, in which the at least one profile distributes the sterile fluid over the containers that are present in the working space, and a second position, in which the at least one profile allows cleaning fluid to enter the working space when no containers are present in the working space. 5. A method comprising: introducing a sterile fluid from a sterile fluid supply into a working space, the fluid being delivered through an external line with several openings, the external line connected to the sterile fluid supply and extending through the working space;conveying containers through the working space, and executing at least one work step on the containers in a sterile atmosphere in the working space; andintroducing a cleaning medium from a cleaning medium supply through an internal line with several openings, the internal line passes through the external line, and spraying the cleaning medium into a space defined longitudinally between the internal and external lines, the internal line connected to the cleaning medium supply, which is different from the sterile fluid supply. 6. The method according to claim 5, wherein the cleaning medium is introduced through the internal line after the containers have been conveyed through the working space. 7. The method according to claim 5, wherein the internal line, designed as a pipe and the external line is designed as a pipe, the external and internal lines being rotated around longitudinal axes relative to each other at least for a predetermined length of time during the introduction of the cleaning medium through the internal line. 8. The method according to claim 5, wherein the sterile fluid is a gaseous sterile fluid that is introduced into the working space, and the cleaning medium is different from the sterile fluid. 9. The method according to claim 5, wherein the sterile fluid introduced through the external line is distributed over the containers in the working space by at least one profile with openings, 10. The method according to claim 9, wherein the cleaning medium is introduced through the internal line after the containers have been conveyed through the working space, and the at least one profile is rotated from a first position, in which containers are present in the working space, into a second position, in which the cleaning medium is applied, after the containers have been conveyed through the working space. 11. The device according to claim 1, wherein each of the external line and the internal line extends from one side of the working space to an opposite side of the working space.
