摘要： The invention relates to a flexible pouch (10) for beverages, comprising at least one closure (14) that is welded in between two free edges (16, 18) of the pouch, whereby the body (22) of the closure (14) welded in between both edges (16, 18) is provided, at least in sections, in the shape of a truncated cone. The invention also relates to a method for producing a pouch (10) of the aforementioned type during which the closure (14) is pressed in the direction of the pouch interior (42) before the welding process is completed.

摘要： The present invention relates to an ultrasonic sonotrode (3) with a sealing surface which is intended for coming into contact with the material to be processed. To provide an ultrasonic sonotrode, an ultrasonic sealing device and a method for ultrasonic processing that avoids complicated positioning of the sonotrode and nevertheless ensures consistently good quality of the weld, it is proposed according to the invention that the sealing surface is formed in two parts and that the two parts of the sealing surface are formed by two sealing surface portions facing each other.
