    Further embodiments will become apparent from the claims and from the embodiment described with reference to the drawings. In the drawings show:
    1 shows a sleeve seal for sealing a limiting opening according to an embodiment of the invention.
    FIG. 2 shows the boot seal of the embodiment according to FIG. 1 with inflated sealing sleeves; FIG.
    3 shows the sleeve seal of the embodiment according to FIGS. 1 and 2 with inflated sealing collars in perspective view;
    Fig. 4 is a door seal for sealing the limiting opening according to an embodiment of the invention and
    Fig. 5 shows a workplace arrangement with the sleeve seal of the embodiment according to FIGS. 1 to 3 and with the door seal of the embodiment according to FIG. 4 in a perspective view.
    Fig. 1, Fig. 2 and Fig. 3 show a sleeve seal 2 of a device for sealing a limiting opening 4 according to an embodiment of the invention. The boot seal 2 is provided for installation in a boundary of a working area designed as a clean room, so that a container or a drum can be introduced at least partially through the boundary opening 4 or through the boot seal 2 into the work area. The limiting opening 4 is sealed to the container, so that substances can be reliably removed from the container from the working area without these substances being able to escape through the limiting opening 4 into the environment.
    The boot seal 2 has a base 6 with an example of metal existing rigid sen-senring 8 and attached thereto first gasket 10, which is formed as an inflatable tube and, for example, consists of silicone. In Fig. 1, the first gasket 10 is not inflated. Fig. 2 and Fig. 3 show the first gasket 10 in the inflated state. The inflation takes place by means of compressed air, which is provided by a compressed air source, such as a compressor. By inflating the first sealing collar 10, a first opening width 12 or a clear diameter of the limiting opening 4 decreases.
    The sleeve seal 2 has an adapter 14, which is fastened reversibly in the limiting opening 4 by means of fastening means 16, 16 'and 16 ", which are here designed as screw connections, for example 18 and a second sealing cuff 20 fastened to it The second sealing cuff 20 is designed as an inflatable tube, which is made of silicone, for example, like the first sealing cuff 10. For inflating the second sealing cuff 20, this second sealing cuff 20 is provided with the same compressed air source as the first sealing cuff 10 1 and 2. Fig. 2 and 3 show the inflated second gasket 20. A second opening 22 of an adapter opening 24 provided by the adapter 14 is inflated the second n gasket 20 reduced.
    The boot seal 2 can be used with or without the adapter 14, wherein the adapter 14 can be quickly inserted into the limiting opening 4 by means of the fastening means 16, 16 'and 16 "or removed again from this limiting opening The sleeve opening 2 is therefore capable, by means of the first sealing collar 10, of the limiting opening 4 to a first outer side of a through the limiting opening 4 without the adapter 14 Further, the boot seal 2 is capable of alternatively sealing an annular gap to the adapter 14 by means of the first gasket when the adapter 14 is inserted into the restriction opening 4. By means of the adapter 14 can then seal a remaining annular gap to a second outer side of a projecting through the adapter opening 24 and thus through the limiting opening 4 second container having a second cross-sectional area which is reduced compared to the first cross-sectional area of the first container. Overall, the sleeve seal 2 seals with the support of the adapter 14, the limiting opening 4 to the second outer side of the second container.
    The first sealing sleeve 10 and the second sealing sleeve 20 are connected via compressed air hoses, not shown, with a common input, not shown, of the sleeve seal 2, which in turn is connected to a compressed air source or connectable. A connection leading from the inlet to the compressed air hose, which is connected to the second sealing sleeve, can be shut off or automatically shut off if this compressed air hose is not used together with the adapter 14 in the limiting opening 4.
    The sleeve seal 2 also has in the base 6 around the limiting opening 4 arranged air outlet openings 26 in the form of an annular circumferential ventilation grille. The base part 6 has a plurality of supply air connections 28, 28 ', 28 "and 28'" that can be connected to a fan, via which supply air can be guided from the fan to the air outlet openings 26. The air emerging from the air outlet openings 26 ensures an air flow, which leads away from the boot seal 2 and therefore an accumulation of particles or liquids on the first gasket 10 and the adapter 14 and on the second outer side of the second container or on the first outside of counteracts the first container.
    Alternatively to the embodiment shown, at least one further second adapter may be provided, which is positioned within the adapter opening 24, as the illustrated adapter 14 is positioned in the limiting opening 4. This achieves a further reduced opening width compared with the second opening width 22, which makes it possible to seal to containers or barrels with an even smaller diameter or smaller cross-sectional area.
    Fig. 4 shows a door seal 30, by means of which the limiting opening 4 can be sealed or completely closed when there is no container in the limiting opening 4 or when the first or second or another container inserted into the limiting opening 4 or from the limiting opening 4 is removed or when the lid of the respective container closes the respective container. In particular, it is possible by means of the door seal 30, first to keep the limiting opening 4 closed, to receive the lid of the container and thereby open the container, then to save space the limiting opening 4 and thereby take the lid of the container. A closure of the limiting opening 4 and the container is possible in the reverse order.
    The door seal 30 has a door 32 which can be sealingly applied to the limiting opening 4. For this purpose, the door seal 30 has a lifting device designed as a first displacement device 34 and a second displacement device, not shown, for example in the form of a pneumatic cylinder, by means of the first displacement device 34 and door 32 parallel to the passage direction through the boundary opening or perpendicular to a main front of the door 32 can be moved. The first displacement device 34 allows a vertical lifting or lowering of the door 32 perpendicular to the passage direction. For opening and closing the container or for receiving the lid, the door seal 30 has an actuator 36 with an actuator plate 38. The actuator 36 comprises, for example, at least one hydraulic cylinder which can displace the actuator plate 38 in the passage direction. Furthermore, suction cups 40, 40 ', 40 "and 40"' are arranged on the actuator plate 38, which can suck in the lid of the respective container and thus fix it relative to the actuator plate 38. Starting from not shown air outlet openings in the door 32, the cover is lapped after aspiration with clean room air to prevent contamination of the lid and the door 32.
    5 shows a workstation arrangement 42 with the cup seal 2 and the door seal 30. While FIG. 4 shows a rear side of the door 32 with the actuator plate 38, part of a front side of the door 32 is visible in FIG. which faces the interior of a working area 44 designed as a clean room. The limiting opening 4 and the cup seal 2 are arranged in a boundary 46 of the working area 44, which limits the working area 44 relative to the surroundings or with respect to a region of the work station arrangement in which a container is lifted, rotated and partially cleared from the container in the direction of passage the limiting opening 4 can be pushed, so that the lid of the container from the working area 44 is accessible.
