. -Self-locking stopper to close the bottle

The innovation relates to a self-locking stopper, formed in one piece from elastic plastic, for closing bottles, the neck of which has an outer circumferential bead below the mouth of the bottle, to which a neck part with a possibly steadily increasing diameter adjoins, with a head part designed as a handle, a tubular stopper part formed concentrically on the head and having a smaller diameter than the head, the outer ring-shaped sealing lip that clings to the inner surface of the neck when the stopper is pressed into the bottle mouth, and one formed on the underside of the head via a circumferential separating connection shell portion of an annular ^1, having when pressing the closure on the bottle elastically snapping under the outer bead of the bottle neck inner bead and is provided with a bottom on the edge of the skirt downwardly projecting tear tab, to which at least a continuous tear zone connects from the lower edge of the jacket to the separating connection.

Such stopper closures can be opened after filling of the bottle on the bottle mouth and through axial Pressure on the head of the closure - with its hollow plug part

The one-piece production of the closure from elastic plastic, in particular from thermoplastic material such as polyethylene or polyvinyl chloride, can be carried out using known molding processes, for example by injection molding. The very extensive chemical neutrality of the plastic material prevents undesirable influences. . des-bottle contents for drinks _? like wine or the like, keep their pure ... taste.

The one-piece "fastener" has a handle formed head part 1., which consists of an upper end disk of circular I-shape and about 1 mm thick, the one has outwardly fluted collar 3 extending downward from its edge parallel to the closure axis. At the ' Underside of the disc 2 sit radially from the collar 3 inward-running "stiffening webs 4, which extend up to about extend to half the diameter of the face, this formation of the head gives the head part of the closure, a sufficiently great rigidity that it is considered practical Rigid handle used for handling the lock can be * jtn the underside of the upper end disk 2 of the head part 1, a tubular plug part 5 is concentric at. the head molded j, it is through .one of his End faces with the inner bottom surface of the head part and. through its cylindrical surface with the inner ends of the stiffening webs directly connected. This tubular © Plug part 5-has a smaller diameter than the inner one .Diameter of the bottle neck to be closed and is provided with two annular sealing lips 6, 7th, the to "taper" towards the outside .. In the section, the cross-section has each lip, roughly the shape of a pointed dome, the is inclined slightly downwards. The "outside diameter of the J, sealing lip- is 1.1 to 1.5 times larger than the through-: knife of the tubular.stop part 5 *

The plug part 5 has a length of about 20 mm, of which about 13 to 15 mm. protrude below the level of the underside of the headboard. The sealing lips 6 _S 7 run on the circumference: parallel to each other and are about 5 mm apart. The cylinder diameter of the plug part 3 is about 15 mm, while the diameter of the head part is about 30 mm. '.

The dimensions mentioned above are only exemplary values specifiedf. they. can of course be changed and be adapted to different sizes of bottles.

The jacket part 8 ″ serving to hold the closure on the bottle neck is smooth and cylindrical on the outside, its outside diameter is equal to the outer diameter of the head part 1. The length of the jacket 8 is chosen such that its lower edge lies roughly in the same horizontal plane as the lower band of the cylindrical plug part 5.

.. The jacket part 8 has an inner annular shoulder 9 "From this shoulder, the wall thickness of the jacket gradually decreases to its lower edge, resulting in a slightly conical .Extension of the lower part of the Maiatelteiles.

The jacket also has a tear-off intermediate piece on, that between two-parallel to the closure axis in the inner wall des.Mantels provided grooves 12 is located. This intermediate piece 11 carries a tear tab 15 » extends freely downwards. -

The mode of action of this self-locking fastener is as follows.

TJm a bottle too. close, the clasp is on the neck. the bottle like that. put on,. that the wall of the "neck lies between the jacket 8 and the pipe plug 5" Then the closure is pressed in, for example by hand, so that the stopper with its sealing lips penetrates the neck and see the jacket pushes it onto the outside of the neck, until the shoulder 9 snaps elastically under MLb "of the outer bulge 10 of the placket neck. During this pressing in, on the one hand the sealing lips' 6, 7 are pressed elastically against the inner wall of the bottle neck, and the latter nestle tightly and thus secure a seal. Conclusion, the bottle.ι on the other hand occurs an elastic stretching and deformation ^{1 of} the jacket, which hugs the outer surface of the neck. The shoulder 9 becomes the outer surface of the neck due to its own elasticity, the jacket against

pressed below the bead 10 so that the closure is secured and locked in this closed position.

It is now no longer possible to re-lock without partially destroying it.

When trying to open the lock by pulling on the head γόη deduct the bottle mouth, "the jacket remains with its inner shoulder on the underside of the bead 10 clamped and the individual connection points between the thin-walled upper part of the jacket and the ribs of the The sealing head will tear off. The lock is so strong then damaged, that its forcible opening can be recognized without further ado, is. When trying, by pushing up the coat to push the cap off the neck of the bottle - with the einaelnen connection points between the jacket and the Verschrußkbpf are only subjected to pressure - can because of the locking effect of the shoulder 9. Tearing the Mantels.in the area of. the intermediate piece 11 on both sides not avoiding the delimiting gutters 12? also in this case the closure is so badly damaged that the buyer recognizes this immediately j he will be a bottle with such a damaged Can reject closure without further ado, because which, suspicion .of a ". transfer" is obvious.

■. In order to open the closure normally, the tearable intermediate piece is first torn off by pulling up "the tear tab 13".

I.e., along a line along which the coat only is connected to the handle by individual connection points. The coat can thus be torn off from the head, namely along a line which is located above the shoulder 9. This shoulder 9 only serves to hold the closure on the neck and not to seal the hash. This is immediately apparent, since the coat is not tightly connected to the head, but only by individual connecting points, between which there are gaps

The handle and the stopper part, which is firmly connected to the head, can then be used as a MaehverSchluß for the normal Use- serve, - \ d., H. until the area is completely empty.
