CLASS 64: dispensing equipment.

Patented in the German Empire on September 21, 1897.

The subject of the present invention is a safety stopper intended for bottles and other containers, which stopper is used for pouring of a liquid in measured equal amounts, as well as the counting of those that have taken place Allows emptying. It is characterized by the combination of one with two through openings equipped tap with a disc valve arranged inside the stopper, so that the emptying of the bottle or Container contents can be made in measured amounts, using a counting device indicates the number of equally large quantities of liquid dispensed through which the filling or addition of another foreign liquid is prevented, when the bottle or container is wholly or partially emptied.

Fig. Ι shows a view of the above Safety plug,

Fig. 2 in vertical section the same with the disc valve in the position which the latter after the liquid has been introduced into the one provided for measuring it Occupies space while emptying the liquid.

Fig. 3 also shows in vertical section the position of this disc valve during the Introducing liquid into the measuring space.

FIG. 4 shows in detail the one position of the lifting thumb during emptying, FIG. 5 the position of this lifting thumb acting on the disc valve spindle for insertion of liquid in the Mefsraum.

The cock plug α is pierced by a channel b for the liquid and by a channel c for the air. While the liquid is being emptied, channels b and c are exactly in line with channels b ¹ and c ¹ in the tap body and end in a measuring space d, which is provided in plug j>.

The upper end of the spindle e of the valve / ¹ presses under the action of a helical spring g against a lifting thumb h placed on the cock plug, a.

On the cock plug α also sits a screw without an end i in engagement with a helical gear k; the number of teeth on the latter is equal to the number of partial quantities of the liquid to be conveyed out of the container. A ratchet wheel t sitting on the cock plug α prevents the said plug from rotating backwards by means of a locking cone m which sits on the frame η of the wheel k.

The counting device is covered by a sleeve-like cover ο.

The mode of operation of the device is as follows:

If it stands still, the disc valve f , which is provided with a covering made of cork or other suitable material, rests on its seat. If you now turn the cock plug α by 180 °, the lifting thumb h pushes the valve spindle e downwards, which entrains the valve and liquid can enter the measuring chamber d if the bottle is overturned. Now turning the tap to a further i8o °, then the disc valve is f back to its seat, and the d is introduced in the liquid may Mefsraum through the channels b ^l and b passing by contact aufsen.

Claims (1)

During the turning movement of the stopcock the wheel k has been set in rotation by the screw without end i by a certain arc, which is repeated with each rotation of the stopcock until the entire content of liquid previously contained in the bottle has escaped. At this moment the machine is locked, because there is a toothless part A ¹ on the wheel k ; any rotation of the cock in the opposite direction, either during the partial emptying of the liquid contained in the container or after the complete emptying of the latter, is prevented by the switching cone W, which constantly engages the teeth of the wheel /. Is z. B. the Mefsraum m ^l j _{iQ of} the total content of the bottle, the wheel k is locked after the fortieth emptying, after which the container is completely emptied. If, during the partial emptying of the bottle, one tries to fraudulently pour another liquid into the latter, the wheel k will block the apparatus after its rotation, i.e. after the fortieth emptying, and the refilled liquid would be retained in the measuring chamber, so that one would immediately recognize the deception. The same will be the case when the bottle is completely emptied if one tries to fill the latter again, since the liquid filled in would also be held captive by the blocked counting device. A pointer arranged outside the apparatus can be connected to the wheel k , which is positioned in front of a dial, so that the number of equal parts of the liquid dispensed from the bottle is marked. Instead of inserting the stopper directly into the neck of the bottle, it can be made into a ring Cork or other suitable mass can be used. Once the bottle has been emptied, it is sent to the factory with its stopper back, in which the counter is reset to its starting point. The apparatus described can be attached with a fine iron wire or in some other way attached to the bottle and secured with a lead seal or with sealing wax and the like will. Patent-Α ν saying: A safety plug with Mefs- and counting device for bottles and similar containers, characterized by a cylinder (d), the lower opening pressed down by means of the spring against its seat and by Hubdaumen (h) and following from the same Off The Scheibenyentil) is completed, wherein the Hubdaumen (h) is connected to a cock plug (a) and thus actuates valve (f) when the latter is turned, while at the same time through a washer (i) attached to the cock plug (a) and provided with a thread by means of a gear fk), which receives a non-toothed point serving for locking, a counter is driven.
