A dispenser for discharging a pharmaceutical or cosmetic medium having a discharge head with a discharge opening, a container for storing the medium prior to discharge, elastically deformable outer container, and a dimensionally flexible inner container arranged in an interior of the outer container. A ventilation channel is provided, through which the interior of the outer container is connected to an environment for pressure compensation by compensating air. The ventilation channel is delimited in at least some regions by a self-adhesive label, or ventilation channel has a self-adhesive label and has a gas-permeable surface portion. The gas-permeable surface portion is arranged in the ventilation channel or on one of the ends of the ventilation channel, such that the air passing through the ventilation channel also passes through the gas-permeable surface portion. |

1. A dispenser for discharging a pharmaceutical or cosmetic medium, with
a discharge head having a discharge opening and a container for storing the free-flowing medium prior to discharge, comprising
an elastically deformable outer container anda dimensionally flexible inner container, which receives the medium and which is arranged in an interior of the outer container,wherein
a ventilation channel is provided, through which the interior of the outer container is connected to an environment for the purpose of pressure compensation by means of compensating air,wherein
the ventilation channel is delimited in at least some regions by a label, in particular a label that is self-adhesive in at least some regions, and the ventilation channel is designed in at least some regions as a capillary channel, wherein the capillary channel preferably has a minimal cross-sectional surface area that is smaller than 1 mm2, and wherein the quotient of the length of the capillary channel and of the mean cross-sectional surface area of the capillary channel is greater than 200 mm−1. |
