Abstract: 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.

Abstract: A packaging unit having two planar elements arranged on each other that form, by virtue of being spaced apart in certain regions, a closed chamber between each other and 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 a controlled dispensing of a medium stored therein, an opening element that is disposed on a side of the chamber facing away from a first edge section of the outer edge. Provision is made that the collar region has a support section that is deflectable from an initial position, about a deflection region away from the opening means into a supporting position, in which the support section together with the first edge section form spaced-apart leg means whereby the packaging unit is rendered standable.
