If a cap of the type described above is known (Austrian patent specification 245415), the lower bead-shaped edge of which is heavily bemeaaen and is provided with an inclined edge that an opening tool of the type usual for zaetallene crown corks can be admitted. A bottle closed with the known closure cap is opened in the same way as before, although the elastic closure cap cannot be deformed and can thus be used for reclosing. Apart from the fora of the outer hanging wall, which lies elastically close to the bead neck edge of the bottle, the known closure cap seals with the aid of its inner ring wall. Piping is considerably longer than the outer wall Hing _t Seals and has in front of jumps, rsit which it lies inside the bottle neck. In order to make it easier to grasp this closure cap, in particular when it is reassembled, the outer surface of the outer fiing wall has a hand grip. In order for the well-known closure cap to sit firmly and tightly on the filled bottle, which in many cases contains a carbonated liquid filled under pressure, mechanical application is essential.

vertically movable underlay under a lumber-like opening. A press cone is located above this opening. The metallic crown cork intended for the bottle is clay from a sorting device that brings it into the correct position, alttela air is blown over the opening. At this stage it still has a conically protruding edge, with which it atoes over the opening. The bottle is now moved up through the opening, does not open the cork and is pressed with it into the feeding cone. Pieeer adapts the crown cap to the neck of the bottle. Then the bottle sinks back down through the opening, old from the cork. The opening diameter is dimensioned so that it allows the bottle neck with the adapted crown cork to pass through. If a closure cap made of elastic plastic already has the same external diameter as after it is placed on the bottle neck, it will not find a hold on the opening. Also completely unsuitable for such closures are known closure caps made of elastic © ® plastic which, when opened without tools, are provided with a tear-off or tear-off edge, which have protruding strip ends and / or tabs for gripping. These known closure caps would indeed remain over the opening, supported on these noses. However, the bottle closed in the manner described above could no longer be moved back through the opening.

The object of the invention is to design a closure cap of the type described at the outset with simple means so that it is in the existing, previously with metallic Used crown capping machines can be.

The object is inventively achieved in that the protrusion protruding outwards around the lower edge of the outer hanging wall is of such strength that it is able to take the weight of the cap on an annular support surface, but under the weight of the filled bottle "to bend.

The projections thus enlarge the outer diameter of the cap in the normal case Rests on the opening camouflage about 1 mm, while the enlargement with high-curved projections is nor 2/10 mm. This difference allows the fouled bottle to be lowered through the appropriately sized opening.

The tabs can be approximately semicircular. Its rounded end makes it easier to slide down over the edge of the opening.

In another embodiment, the flaps have günetigerweise their greatest width in the distance from the lower edge, thus they are, where they are bent, narrower and easier to bend, while her hand region with which they _t support the sap on the opening else has a larger area.

The projections are advantageously spaced apart from one another which is about twice its greatest width. This avoids excessive air resistance when the closed bottle is moved back through the opening occurs that would slow down the bottle movement.

The projections can be injection-molded in one piece with the closure cap in an economically advantageous white. Except the unique formation of a spray tool tooth thus no additional manufacturing costs due to the projections, since their material requirements compared to the total does not matter.

A closure cap according to the invention with a ribbon edge on the outer surface of the outer ring wall is therefore designed according to the invention so that a smooth-walled strip of at least 4 meters in height runs around between the knurled edge and the cap top. This smooth band enables the conventional sorting device to test the closure cap for its correct position and, if necessary, to bring it into this.
