Abstract

A packaging container having a discharging or docketing device for allowing uninterrupted aseptic connection to for instance a hose having an orifice. The container has a channel (13') of a flexible material terminated by a grip flap (16). The flap (16) is torn away along tearing denotations (17, 17') and weakenings (19, 20) for opening the channel. By locating the weakenings (16) such that they do not coincide there is obtained at least one protruding portion which will expose portion on the inside of the channel when the channel is opened up. This portion then acts as an entering surface for facilitating connection.
