Patent attributes
A device connects a storage container to a working reservoir for transferring a substance from the storage container to the working reservoir. The device includes a housing which is joined to the storage container with either a fixed connection or a coupling means. A passage opening is formed on the housing, and a shutter that is movably connected to the housing serves to close the passage opening. The shutter has a connector port for each working reservoir. The shutter moves in a rotary or sliding manner relative to the housing between an open position and a closed position. In the closed position, the passage opening is closed off by the shutter, and in the open position the interior space of the storage container is connected through the passage opening to the interior space of the working reservoir which is seated in the at least one connector port.
