Abstract

A sealing member inside the bag and a withdrawing member outside the bag can be interplugged and cooperate by complimentary conical sealing surfaces to dispense flowable material from the bag. A retaining member is attached to the outer side of the bag wall and clamps a portion of the bag wall between the retaining member and the sealing member to allow a plastic deformation of that portion by the withdrawing member until it ruptures.
