Abstract (en)
[origin: EP0591777A2] In the case of a method for manufacturing a discharge vessel whose discharge volume (3) is sealed by a single pinch (4), the discharge volume (3) is produced in its final shape (by means of blow moulding) at the same time that the open end (25) is sealed. An incline (17) is advantageously formed on the narrow sides (14) of the pinch in this case. <IMAGE>
