A packaging unit having two planar elements arranged on each other to form, by virtue of being spaced apart in certain regions, a closed chamber and that are joined to each other in a collar region encircling the chamber, the collar region being bounded by an outer edge. The chamber has, for controlled dispensing of a medium stored therein, a tapering extending into a detachable section that is detachable from the collar region and on which a predetermined break line intersecting the tapering is provided for creating an opening at the tapering. Provision is made that the detachable section is bounded by a material weakening that is recessed at a distance from the outer edge into the collar region and separates the detachable section from a protective section of the collar region that covers the detachable section toward the outer edge.

The packaging unit according to claim 1, wherein the protective section (28) has, in extension of said predetermined break line (24), an increased bending stiffness relative to said predetermined break line (24). 3. The packaging unit according to claim 2, wherein said predetermined break line (24) is bounded by the material weakening (26). 4. The packaging unit according to claim 1, wherein said at least one stabilizing means (36) is formed by a deep-drawn region (38). 5. The packaging unit according to claim 4, wherein said deep-drawn region (38) extends in a U-shape about said detachable section (22). 6. The packaging unit according to claim 5, wherein said material weakening (26) has two weakened sections (30) that extend on opposite sides of said tapering (18) crosswise to said predetermined break line (24). 7. The packaging unit according to claim 6, wherein each of said two weakened sections (30) extends on a respective side of said outer edge (16). 8. The packaging unit according to claim 6, wherein said material weakening (26) extends in a U-shape about said tapering (18) and said two weakened sections (30) are formed by opposed sections of said material weakening (26). 9. The packaging unit according to claim 8, wherein said U-shaped material weakening (26) extends on both sides to said outer edge (16). 10. The packaging unit according to claim 8, wherein said U-shaped material weakening (26) has two ends (32) disposed at a distance from said outer edge (16). 11. The packaging unit according to claim 10, which has a length along which said material weakening (26) is formed by a cut. 12. The packaging unit according to claim 11, wherein said material weakening (26) is provided, over the length of the cut, with a plurality of adhesion points (40). 13. The packaging unit according to claim 10, wherein said material weakening is formed by perforations (42). 14. The packaging unit according to claim 13, wherein said predetermined break line (24) is formed by creasing and scoring. 15. The packaging unit according to claim 1, further comprising a peelable foil (44) that adheres to said detachable section (22) and to said protective section (28). 16. The packaging unit of claim 1, wherein: the two planar elements comprise a part that surrounds the tapering;said material weakening (26) has two ends (32) disposed at a distance from said outer edge (16), and is configured to allow bending of the protective section (28) relative to the remaining collar region so that the packaging unit can be set down substantially upright after opening; andsaid protective section is joined to said part that surrounds the tapering by a connection along said material weakening that is constructed to be broken to allow the bending of the protective section (28) relative to the remaining collar region. 17. The packaging unit of claim 1, wherein said protective section is constructed and positioned for shielding the detachable section and the predetermined break line and stabilizing the detachable section and the predetermined break line against inadvertently applied forces, so as to prevent a premature unintentional breaking of the predetermined break line, and thereby prevent medium that is stored in the chamber from leaking out. 18. A packaging unit (2) comprising: two planar elements (6, 8) arranged on each other that form, by virtue of being spaced apart in certain regions, a closed chamber (12);a collar region (14) that joins said planar elements to each other and that encircles said chamber (12), said collar region (14) being bounded by an outer edge (16);a detachable section (22) that is detachable from the collar region (14) and on which a predetermined break line (24) intersecting a tapering (18) is provided for creating an opening at the tapering (18);wherein said chamber (12) has, for a controlled dispensing of a medium (4) stored in said chamber, a tapering (18) extending into said detachable section (22);a protective section (28) in said collar region (14) that partly surrounds said detachable section (22) toward said outer edge (16);a material weakening (26) that bounds said detachable section (22) and is recessed at a distance from said outer edge (16) into said collar region (14) and separates said detachable section (22) from said protective section (28); andat least one stabilizing means (36) in said collar region (14), that is in extension of said predetermined break line (24) and is formed by a deep-drawn region (38), to stiffen the protective section (28), wherein said deep-drawn region (38) extends in a U-shape about said detachable section (22);wherein said material weakening (26) extends in a U-shape about said tapering (18) and has two weakened sections (30) that are formed by opposed sections of said material weakening (26) and extend on opposite sides of said tapering (18) crosswise to said predetermined break line (24), and said U-shaped material weakening (26) has two ends (32) disposed at a distance from said outer edge (16), and is configured to allow bending of the protective section (28) relative to the remaining collar region so that the packaging unit can be set down substantially upright after opening, andwherein said two planar elements are joined together in said protective section to be fixed in order to form a support that allows said packaging unit to be set down with said tapering facing upward to prevent the medium from spilling out of said chamber. 19.
