Patent ID: 7891526

Claim:
A dosing device for sucking in and expelling a flowable medium comprising a container having an inlet ( 60 ) and a duct ( 62 . 1 to 62 . 4 ), wherein the inlet ( 60 ) and the duct ( 62 . 1 to 62 . 4 ) are disposed separately from one another, a dosing and displacement chamber ( 61 ) is provided and inlet ( 60 ) and duct ( 62 . 1 to 62 . 4 ) are closable and the inlet ( 60 ) and the dosing and displacement chamber ( 61 ) are disposed in a housing ( 3 ), wherein the inlet ( 60 ) opens into the dosing chamber ( 61 ) and wherein attached to the housing ( 3 ) and the inlet ( 60 ) is a suction pipe ( 31 ), through which the flowable medium may be sucked into the dosing and displacement chamber ( 61 ), and wherein there is inserted into the housing ( 3 ) an actuating element ( 1 . 1 to 1 . 4 ), in which the duct ( 62 . 1 to 62 . 4 ) is provided, wherein an ascending tube ( 7 . 1 to 7 . 4 ) in the actuating element ( 1 . 1 to 1 . 4 ) interacts with the duct ( 62 . 1 to 62 . 4 ) and wherein on or in the actuating element ( 1 . 2 to 1 . 4 ) a spout ( 20 . 1 , 20 . 2 , 20 . 3 ) or a rotary lever ( 19 ) is rotatably disposed and the duct ( 62 . 1 , 62 . 2 , 62 . 3 , 62 . 4 ) may be brought into connection with an outlet channel ( 8 . 1 , 8 . 2 , 24 ) in the spout ( 20 . 1 , 20 . 2 , 20 . 3 ), wherein the duct ( 62 . 1 , 62 . 2 , 62 . 3 , 62 . 4 ) for sucking in the medium is closable by means of the spout ( 20 . 1 , 20 . 2 , 20 . 3 ) and/or the rotary lever ( 19 ) but during expelling of the medium is openable by rotating the spout ( 20 . 1 , 20 . 2 , 20 . 3 ) and/or the rotary lever ( 19 ), and wherein by rotating the actuating element ( 1 . 1 ) the duct ( 62 . 1 ) is rotatable out of its connection to the outlet channel ( 8 . 1 ) of the spout ( 20 . 1 ), wherein the outlet channel ( 8 . 1 ) is closed by means of the piston ( 2 ).
