Administration device and method for producing same

A delivery device, comprising:

• a base body defining
• a chamber for receiving a flowable substance to be administered, and
• an outlet opening, the outlet opening comprising an outlet chamber for receiving the flowable substance from the chamber,
• wherein the base body is composed of a first film portion and a second film portion, the first and second film portions being attached to each other by a connection, the base body being configured to discharge or extract the substance through the outlet chamber and the outlet opening by compressing the chamber;
• a pouring adapter composed of a resilient material that substantially maintains its shape when the chamber is compressed in order to discharge the substance, the pouring adapter having a channel extending from a first end to a second end thereof, the pouring adapter including
• a sealing portion having a quasi-triangular shape in a front view, the sealing portion being arranged between the first film portion and the second film portion to be securely connected thereto, within the outlet opening of the base body, such that the channel of the pouring adapter is in fluid communication with the outlet chamber of the base body, and
• a connector portion extending from the sealing portion, the connector portion being configured to be connected to a fitting part such that the channel of the pouring adapter is in fluid communication with the fitting part;
• and
• a fitting part comprising one of a spout, a droplet dispenser and an injection needle of a desired length mounted on the connector portion of the pouring adapter in accordance with a desired mode of administration of the substance from the delivery device, wherein the desired mode of administration of the substance comprises one of spraying, dropping, spreading and injection,
• wherein the connection of the first film portion to the second film portion seals the chamber and has a plurality of regions that include a more resilient region and a less resilient region, the less resilient region being located between the chamber and the outlet chamber, and
• wherein, when the chamber is compressed, the more resilient region is designed to remain connected and the less resilient region is designed to come undone in order to discharge the substance essentially exclusively through the outlet chamber, through the channel of the pouring adapter and finally through the fitting part.
