A dispenser for dispensing a liquid or pasty compound that has a dispenser head which has a dispenser opening and a dispenser lower part, a storage chamber, and a pump device in the dispenser head. The compound can be dispensed out of the storage chamber via the dispenser opening by the pump device. The storage chamber is additionally produced as a bag-like storage chamber part and is received in the dispenser lower pat in a replaceable manner. The storage chamber part has an adapter part for interacting with the pump device in order to conduct the compound, and the adapter part has a cover element which can be acted upon in order to form an opening of the storage chamber. A seal wall which extends so as to surround the cover element is suitable for sealingly interacting with the dispenser.
1. An adapter part configured for arrangement in a passage to a storage chamber of a dispenser, comprising:
a cover element that is configured to be acted upon in order to form an opening,
a seal wall that circumferentially extends to the cover element, the seal wall being configured to interact with the dispenser in a sealing manner, and
a cylinder section, an outer cylinder surface of which is provided for connection with a container part of the storage chamber, wherein the outer cylinder surface transitions into a cylinder floor that runs at essentially a right angle to the outer cylinder surface and/or the seal wall extends at essentially a right angle to the cylinder floor, wherein on a top side of the cylinder floor, facing away from the storage chamber, a seal collar is formed in one piece with the cylinder floor and the cylinder section.
2. The adapter part according to claim 1 , wherein a holding-open part provided to protrude into the storage chamber is attached to the adapter part.
3. The adapter part according to claim 1 , wherein the cover element is designed as a film and/or the cover element is formed by a plate part that has a circumferential weakened area, wherein the plate part transitions into a surrounding area of the adapter part in a materially uniform manner via the weakened area.
