A disposable-type flexible bag is sealed by means of a male part 10 which is inserted into a female part 15. Locking is effected by a bayonet socket 12,17. For emptying of the bag, a sleeve part 19 is used which is screwed to the female part 15 and is provided with an emptying duct 22. The sleeve part encloses a tubular plunger 23 provided with a drainage opening 24 and directed relative to the sleeve part by an axial groove 27 and a peripheral groove 28. An axial displacement of the tubular plunger in a sleeve part fitted to the female part forces the male part out of the female part and guides the drainage opening 24 to a position level with the emptying duct 22. A rotation of the plunger guides the opening to coincide with the duct so that controlled emptying of the bag can take place. <IMAGE> |
