  • Patent number: 8555934
    Abstract: The invention relates to a method for filling and evacuating a dispenser unit for paste-like, foam-form or liquid media. In the known methods, a storage container is evacuated via a suction pump, which otherwise serves for the delivery of the medium, after filling. The risk exists hereby that medium is drawn in. In order to make the drawing-off process more effective and more reliable, a method and a filling insert for a dispenser unit are proposed according to the invention, wherein at least one air duct is provided parallel to the suction pump. The evacuation takes place by the application of a pressure difference between storage container and the environment, which is just so great that air can in fact be drawn through the air duct but no viscous medium can be drawn.

  • Publication number: 20110121038
    Abstract: 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.
