Dosing device

The invention relates to a metering device of the type mentioned in the preamble of claim 1 for Liquids. As the container mentioned in the preamble, for. B. a plastic canister or a plastic bottle to serve.

The invention is intended to provide a metering device with a measuring vessel that is squeezed of the container or bottle can be filled completely or up to a mark, but with a backflow of the Liquid. Should be prevented from entering the bottle. These The object is achieved by the invention according to claims J.

When the container is squeezed, liquid is passed through the pipeline mentioned in claim 1 and the valve pressed into the measuring cup. As soon as the pressure on the container ceases and the container has the tendency to • - to expand again closes the valve so that no liquid can flow back.

It is necessary that air can enter the container again. A special ventilation valve could be used for this purpose be provided on the container or its closure. In a further development of the invention according to claim 2, however, the valve designed so that it itself provides the necessary ventilation. In addition, there is no need for a valve spring. The claim 2 called ball is under the influence of gravity

pressed against their seat. Then the measuring cup for Inclined to pour out, so the sphere finally leaves its Sit, but only when the measuring cup is tilted so strongly that no more liquid flows through the now opened one Valve can enter the pipeline.

In a further development of the invention according to claim 3, two j The main components of the metering device are designed so that they I (_> can be put together, namely the locking part with an- J set pipe socket and valve seat and on the other hand the j measuring cup, which with a piece of pipe in its bottom under Ab- I seal is to be placed on the pipe socket of the closure part. As a result, the pipe socket is also on the outside • closed, so that the ball is locked in and only one or more passage openings for the liquid remain.

Through a further development of the invention according to claim 4} is achieved that the measuring cup after Aufprellen on the pipe} clip securely holds, seals against liquid and on-j

.-. is rotatable over the pipe socket. In this way can be \ * - "through holes in the tube section of the measuring cup and the tube clip obstruct each other or brought into line so that dann.Flüssigkeit might escape.

By a development of the invention according to claim 5 is a space-saving arrangement created and achieved at the same time, that the measuring cup has a secure hold on the shoulder of the container, in particular a bottle, so that the pipe socket and the tube is protected against breaking in the measuring cup base

An embodiment of the invention is based on the following described in the drawing.

The only figure shows the upper end of a plastic bottle, the lower part of the measuring cup and the metering device.

From the plastic tab 1 is only the upper end with the , Shoulder 2 shown. The bottle has a usual one

Screw thread connector 4.

r ~ \ From the measuring cup 6 only the lower part is illustrated. The size of the measuring cup depends on the type of liquid to be dosed. Markings (not shown here) for the amount of liquid are attached to the inside. The outer part 8 of the measuring cup bottom is pulled down against the shoulder 2 of the bottle 1 and can be supported on this. According to the drawing on hand, it is a short distance from the shoulder, but it definitely prevents the measuring beaker from tilting by any significant: · Angle. The middle part 10 is the Meßbecherbodens upward rir "MST> -hi σ crfiwrii ht: and has a DurchbrechunK in the form of a tubular piece 12, which is closed at the top by a cover plate fourteenth The pipe section 12 has a in its right side wall

Q .. passage opening 16.

The cover plate 18 of a screw cap designated as a whole as 19 has a medium breakthrough. At the bottom is a pipe socket 21, onto which a riser pipe 23 is liquid-tight is postponed. At the top is a pipe socket 25, the clear width of which is greater than that of the pipe socket 21. The connection A valve seat 27 for a valve ball 28 is established between the interiors of the two pipe sockets. The pipe socket 25 has a passage opening 30 in at the same height as the passage opening 16. An annular rib 32 is provided on the outside of the pipe socket 25 and on the inside of the pipe section 12 a matching:

annular groove 33..

The metering device described consists of four parts, namely the screw cap with the pipe sockets 21 and 25, the riser pipe 23, the valve ball 28 and finally the measuring cup β with its pipe section 12.

After the valve ball 28 has been inserted into its seat 27, the pipe section 12 is bounced onto the pipe socket 25. It is now held there in a form-fitting manner and is watertight but rotatable. By corresponding rotation about the longitudinal axis 34, the passage openings 16 and 30 can be brought into alignment for pouring or rotated against one another for blocking. On a cylindrical wall piece 36 of the central part 10 of the cup base and on the cylindrical jacket 38 of the screw cap, a rib 40 or 4l is provided. Another rib can be arranged on one of the two parts. This gives stops through which the pouring cell and a blocking position of the passage openings 16 and 30 are easier for the user to find.

O 'For dosing, the bottle 1 is slightly compressed so that Liquid rises up through the riser pipe 23 while lifting the valve ball 28 and through the then aligned Passage openings 16 and 30 in the measuring cup. If the liquid has reached the desired height in the measuring cup and the pressure on the bottle is then reduced, it locks the valve ball 28 from.

If the measuring beaker is then emptied, the valve ball 28 leaves the valve ball 28 in spite of the small amount when the axis 34 is approximately horizontal Vacuum in the bottle, the valve seat under the influence of gravity. Then air can enter the bottle

and the bottle will return to its original shape.
