Abstract
In a film tube containing a flowable substance, a fold 11 is formed in the film, which fold is so shaped that it abruptly decreases the cross-section at this location of the tube. The fold 11 may be fixed by a V-shaped weld 12. When the film tube is compressed, maximum stress is exerted on the area of the film close to the apex 13 of the V-shaped weld 12, so that the tube starts to rupture and form a dispensing opening at this location.
