Abstract: 1. Process for conveying containers (10) past a device (26) for inspecting the container bases (10) for contamination, flaws and foreign bodies, the containers (10) are conveyed to the inspection device (26) by a first conveyor (12) and removed by a second conveyor (16) for inspection, a gap (14) is provided between the first and second conveyors (12, 16) within which the containers (10) are not supported at least not on their entire standing surfaces from beneath, the containers (10) on the first conveyor (12), in the gap (14) and on the second conveyor (16) are led through lateral guide devices (24) characterized in that the containers are conveyed at least in the gap (14) under pressure from behind. 2. Process of Claim 1, characterized in that the containers within the gap (14) are conveyed without support on their entire standing surface. 3. Process of Claim 1 or 2, characterized in that to create the pressure at the beginning of a working shift and/or to remove the pressure after finishing the working shift several mechanically-bound cylindrical bodies (35) are conveyed before the several first containers and correspondingly after the several last containers. 4. Device for conveying containers (10) past a device (26) for inspecting the container bases (10) for contamination, flaws and foreign bodies, the containers (10) are conveyed to the inspection device (26) by a first conveyor (12) and removed by a second conveyor (16) for inspection, a gap (14) is provided between the first and second conveyors (12, 16) within which the containers (10) are not supported at least not on their entire standing surfaces from beneath, the containers (10) on the first conveyor (12), in the gap (14) and on the second conveyor (16) are led through lateral guide devices (24), passing along both sides of both containers (12, 16) and the gap (14), characterized in that the side guide devices are arranged at a distance, to convey the containers (10) under pressure. 5. Device of Claim 4, characterized in that the containers within the gap (14) are conveyed without support on their entire standing surface. 6. Device of Claim 4 or 5, characterized in that said side guide devices are made as fixed rails. 7. Device of any Claim 4-6, characterized in that in case if containers (10) are bottles with a thickened portion at the upper of the neck a fixed neck guide (29) is provided and arranged slightly below the thickened portion of a bottle. 8. Device of any Claim 4-6, characterized in that a transparent plate (28) adjustable by height is provided within the gap (14) said plate serves for height regulation of the conveying plane (22) to support containers before and after the working shift and during conveying the containers under pressure to provide its lowering. 9. Device of any Claim 4-6, characterized in that said transparent plate made of glass is arranged within the gap (14) below the level of the first and the second conveyors (12, 16). 10. Device of any Claim 4-6, characterized in that said side guide devices are made within the gap (14) as rollers (30) with a vertical axis of rotation, wherein the distance between the outer surfaces of rollers (30)is less than the diameter of containers (10)and the length contacting area is less than the length of the gap (14). 11. Device of Claim 4, characterized in that supporting plates (31) with cut-outs (32) are arranged within the gap (14), said cut-outs pass from one and correspondingly from the other side of the conveyor in the direction of conveying and have a length equal to about the container (10) diameter. 12. Device of Claim 4, characterized in that inclined or transverse guides (33) to support containers (10) are arranged within the gap (14), wherein the distance between said guides (33) corresponds to about half container diameter (10).
