Abstract
A drain tube for urine is connected at its distal end to a urine meter. The tube has a predetermined point of weakness so that when the meter is lifted to dump the urine therefrom, the tube kinks off at the point of weakness, thereby preventing passage of urine from the meter back up the drain tube during dumping. The point of weakness is formed by simultaneously stretching and heating a section of the tube while the inner diameter of the tube is held constant on a mandrel.
