Patent number: 9380916Abstract: The invention relates to a dispenser system with a housing, into which a reservoir cartridge is inserted, which is formed by a reservoir container and a distribution device. Housing comprises an actuation device which acts on distribution device in such a way that a pressure on the actuation device delivers a portion of the medium on the distribution device. The known dispenser systems have the drawback that an individual dispenser is required depending on the medium. According to the invention, in order to create an identical part dispenser system, a connection element compensating for the different geometries of distribution device is connected to distribution device. Moreover, actuation device comprises at different levels pressure-exerting faces, which cooperate with pressure-receiving faces of distribution device, wherein different faces engage with one another depending on employed reservoir cartridge.Type: GrantFiled: April 30, 2009Date of Patent: July 5, 2016Assignee: Evonik Stockhausen GmbHInventors: Petra Allef, Annette Zur Mühlen, Bernd Nauels, Markus Pielen
