Claim:
A packaging unit ( 2 ) having two planar elements ( 6 , 8 ) arranged on each other that form, by virtue of being spaced apart in certain regions, a closed chamber ( 12 ), said packaging element having 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 ), wherein said packaging unit further has a detachable section ( 22 ) that is detachable from the collar region ( 14 ) and on which a predetermined break line ( 24 ) is provided, said chamber ( 12 ) has, for a controlled dispensing of a medium ( 4 ) stored in said chamber, a tapering ( 18 ) intersected by the predetermined break line and extending into said detachable section ( 22 ), the predetermined break line ( 24 ) being provided for creating an opening at the tapering ( 18 ), and further wherein said collar region ( 14 ) has a protective section ( 28 ) that at least partly surrounds said detachable section ( 22 ) toward said outer edge ( 16 ), 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, and said detachable section ( 22 ) is bounded by a material weakening ( 26 ) that 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 ), and wherein said collar region ( 14 ) has, in extension of said predetermined break line ( 24 ) at least one stabilizing means ( 36 ) that stiffen the protective section ( 28 ).
