摘要: A dispensing device (D) according to the invention for liquids from flexible packaging, in particular a defined amount of liquid packaging comprising body (1) having generally elongated shape, wherein said at its one end, an inlet fitting (2) is mounted and another end outlet (3) mounted, defines inner space (la) further provided on side surface with connection opening (11), preferably flange (1c) outwardly projecting surrounding connecting (11) resilient bellows (9) attached sealed manner, consisting certain number folds (F), form helical coils (Z), inside (9a) being fluid communication (la). Said (F) or (Z) are adapted flex under pressure exerted bottom (9b) axial direction, towards (1). The assembly stepless adjustment volume dispensed control element (8) cooperating arranged outer and/or around their periphery, least section length (1c).
