Opener and seal for paper cartons containing juices, milk, household and technical fluids

摘要

The cutting point (7) of the cone (3) is curved out to the side by a distance (8) from the principal axis (5) of the opener (6) by at least the radius (24) of the pouring opening (9), and/or displaced by an angle (4) to the principal axis. A drinking straw is inserted in the pouring opening. An elastic sealing ring (20) is located above the cutting point in a tapered section of the pipe (11) and its locking bead (12) lies in the space (13) for a collar (14).
