Abstract: In a method for producing drip irrigation tubes, a body is extruded, from which the tube is formed and in which metering elements (10) are attached, which are connected to the body by means of ultrasonic welding. For such drip irrigation tubes, the water enters the metering elements (10) from the inside of the drip irrigation tubes through inlet openings, flows through the metering elements, and exits the drip irrigation tubes through outlet openings in a metered manner. The body is formed into a tube body, which is flattened, and the metering elements (10) come to be situated in a central region inside this flattened tube body. The flat tube body is fed between a sonotrode (6) and an anvil (7) of an ultrasonic welding device (3), and the metering elements (10) are welded to the walling of the tube body. The invention further relates to a device for carrying out the method.

Abstract: A flexible transport container (1) includes an inner bag (10) formed by a flat casing closed at one end (12), the other end (13) of which is folded towards the first end. The inner bag is housed inside an outer bag (20) formed by a casing provided with a first access port (25) which extends through the two bags close to the closed end of the inner bag and a second access port (27) which only extends through the wall of the outer bag opposite a portion of the folded end of the inner bag.
