Description

The subject of the present invention is a crown cap closure for bottles and the like. With a sealing ring resting on the mouth edge, on which the cup-shaped Metal disc rests with its edge, which is separated from the outer capsule by a crown disc. With the previously known Closures made of cork ο. The use of a good cork was the main requirement. In accordance with the subject matter of the present invention, there is now shown a bottle closure in which the nature of the cork is less important. The seal can be made of an inferior cork, ζ. B. made of artificial cork or glued cork, exist because the bottle contents with the Cork no longer comes into contact. Seals have already become known in which the contents of the bottle no longer come into contact with the cork + what by putting on a metal cap or the like. is prevented. Such seals exist mostly in a ring-shaped cork disc placed over the mouth of the bottle. Many

these bottle closures could not cope with a higher pressure of the bottle contents withstand, because either the cavity was pressed in above the end plate, whereby the contents of the bottle came into direct contact with the cork and dissolved it or gave the contents of the bottle a cork flavor. The subject matter at hand Invention overcomes this deficiency in a simple way by squeezing it in the deep Insert a cork disk into part of the end plate so that even sudden increases in pressure do not bend this disk can., with coming into contact of the bottle contents with the cork excluded is. Furthermore, the cork disc inserted in the bulge offers a much better, more odorless and denser closure as a simply closed metal bottle cap.

The object of the present invention is shown in the drawing in an exemplary embodiment, and it shows

Fig. Ι the clasp in pulled apart-S5 11 representation,

Fig. 2 a section through the neck of the bottle with the cap attached,

Fig. 3 shows a slightly different embodiment of Fig. 1,

Fig. 4 shows the corresponding section through the neck of the bottle.

The seal consists of the cap 1, the locking ring 2, the plate 3 and the insert plate 4. The seal is effected in a simple manner in that the ring 2 is placed on the bottle neck 5 and over it the plate 3 placed so that the plate bottom 6 enters the opening 7 of the ring. then the cork washer 4 is inserted into the bottom of the plate

j placed and the cap 1 pushed over the entire structure.

But it can also be completely inserted into the cap and the seal on the Bottle neck can be turned up.

The insert plate 4 and the ring 2 is chosen in its strength so that it is tight against the lid 1 and bottle neck 5 must be in contact.

In the second embodiment, in order to ensure an elastic closure, another circular disk 8 inserted between the plate and the cap.

It is easy to see that the cork parts do not come into contact with the contents of the bottle come so that they can be made of inferior materials. A Bending of the termination by the internal pressure is just as impossible as the gap between the tarpaulin and the cap is completely filled by the one cork disc will.
