Definitions

• the present invention relates to a metering device for drawing in and discharging a flowable medium from a container having an inlet and a passage.
• Dosing devices of this type are known and used in a wide variety of forms and designs. Dosing devices can be found, for example, in cream containers in the pharmaceutical sector or in sauce containers in the food sector or the like. By simply depressing a pump, the liquid or the like located in the container or the like. The like. Depending on the desired amount, the pump is pushed down more or less. However, exact dosing is not possible.
• the object of the present invention is to provide a metering device which enables a more precise metering of a liquid or the like contained in a container.
• the metering device should be easy to clean and thus be able to be used several times.
• the metering device should be usable for different container sizes and should be easy to assemble and handle.
• the solution to the present problem is that the inlet and the passage are arranged separately from one another, a metering and displacement chamber being provided between them and the inlet and / or passage being closable.
• Such a configuration of the metering device makes it possible to first suck a desired amount of the liquid into the metering and displacement chamber before it is subsequently discharged.
• the passage is closed so that the liquid cannot drain away.
• the inlet is then closed while the liquid is being dispensed, so that no further liquid is accidentally in the dosing and displacement chamber can be sucked and thus falsify the result.
• the inlet is arranged in a housing with a molded screw cap and the passage is arranged in an actuating element, the actuating element being inserted into the housing in a movable and rotatable manner.
• the inlet can be closed with a valve ball, whereas the passage is rotated by the rotation of the actuating element from its connection to a channel for discharging the liquid.
• the actuating element can be designed differently.
• the actuating element is inserted into a piston with an injection-molded beak.
• the beak is provided with the channel, which comes into connection with the passage when the actuating element is rotated accordingly.
• the passage is connected to a riser in the actuating element. This riser in turn opens downwards into the metering and displacement chamber of the housing.
• the actuating element is inserted directly into the housing.
• a beak is rotatably inserted in the actuating element and has the passage. Depending on the rotation of the beak, this passage can be connected to the riser of the confirmation element or rotated out of the connection.
• the culvert is located here a rotary lever, which in turn is rotatably arranged in the actuating element and crosses the riser of the actuating element. By rotating the rotary lever, the passage can be rotated into the riser, so that liquid can be discharged from the riser through the passage into, for example, a measuring cup or the like.
• FIG. 4 Another possibility for the formation of the actuation button is shown by a fourth embodiment.
• An attachment is pushed onto an injection-molded arm of the actuating element when the metering device is used.
• This attachment also has a passage, which comes into connection with the riser of the actuating element when the attachment rotates accordingly.
• Sealing of the individual elements to one another and between media to be discharged and outside air are used, for example, as sealing cams or an annular rib on the underside of the actuating element, which come into engagement with correspondingly shaped recesses in the screw closure when the actuating element is pressed down.
• the actuating element in its extension which is inserted into the metering and displacement chamber of the housing, is provided with a sealing ring, which prevents liquid from the metering and displacement chamber from escaping to the outside.
• a further sealing element is provided in the screw cap, which serves to seal the liquid.

• the screw cap, as well as the actuating element can be provided with knurling, which enable better handling of the screw cap or the actuating element.
• holding ribs are assigned to the housing in the inlet area, between which the valve ball is pressed.
• the holding ribs are intended to prevent the valve ball from floating with the liquid upward during the suction of liquid and thus clogging the opening to the riser in the actuating element.
• Four holding ribs are preferably provided. However, it is also conceivable to arrange fewer or more retaining ribs or a circumferential ring collar. Here, too, there should be no limits to the invention.

• the attachment 22 also has a ring 26 on its outer surface 25. After inserting the attachment 22 into the channel 23 of the actuating element 1.4, this ring 26 engages with a correspondingly shaped annular groove 27 in a wall 28 of the channel 23 and prevents the attachment 22 from slipping out of the channel 23.
• a passage 62.4 is provided in the attachment 22, which, when the attachment 22 is rotated into the “OPEN” position, comes into agreement with the riser 7.4 of the actuating element 1.4.
• Wing-like elements 32 on the outer surface 25 of the attachment 22 facilitate turning the attachment 22 from the “CLOSED” position into the “OPEN” position and vice versa.
