Abstract
A delivery device includes a base body having an outlet opening and a chamber for receiving a flowable substance to be administered. The base body, having first and second film portions attached to each other by a connection with a plurality of regions, being configured to discharge the substance through the outlet opening by compressing the chamber. The delivery device further includes a pouring adapter tightly connected to the outlet opening. The plurality of regions of the connection include a more resilient region and a less resilient region that are arranged between the chamber and the outlet opening. When the chamber is compressed to discharge the substance through the outlet opening, the less resilient region is configured to come undone and the more resilient region is configured to remain connected so that the substance can be discharged solely through the outlet opening and the pouring adapter by compressing the chamber.
