description

The invention relates to a locking device for Bottles with carbonated beverages, in particular for sparkling wine bottles of the type in the preamble of claim 1 specified genus.

The closure device is particularly intended for those bottles that limit the opening of the bottle, The pouring bead protruding radially over the bottle neck and one through a circumferential groove from the pouring bead separate, radially protruding over the bottle neck j contain a locking bead with a larger outside diameter than the pouring bead for such bottles usually contains one which can be inserted into the bottle opening under high tension Stopper on which a cap that extends over the bottle opening is formed. If the stopper closure is the If the bottle is unable to withstand overpressure, the stopper can also be attached with twisted wires Locking bead can be secured, as is usually the case with sparkling wine bottles. When pulling out The stopper spreads so widely that it is usually no longer inserted into the bottle opening by hand can be. With the known closure devices, sparkling wine bottles can no longer be opened can easily be locked and stored.

The invention is therefore based on the object of a locking device To create the type specified at the beginning which, when the stopper is inserted, has a shapely, reliable seated closure of the bottle and which allows a reclosure when the stopper is pulled out, the able to withstand the carbonic acid pressure building up in a sparkling wine bottle.

In order to achieve this object, that stated in claim 1 is provided Combination of features suggested. Further advantageous refinements and developments of the invention result from the subclaims.

With the cap according to the invention, which is a separate from the stopper Plastic molding is that with a cylindrical shell part open on one side under elastic pretension can be pushed onto the pouring bead up to the stop of its opening edge against the upper ring shoulder If the elastic pretensioning is suitable, the uncorked bottle can be resold for storage purposes possible. The pretension is also sufficient to hold the cap in the pouring bead of the corked bottle. A further improvement in this regard is thereby made in accordance with a preferred embodiment of the invention achieved that the cap protrudes at least four at equal angular distances from each other towards the interior of the cap has arranged ribs, the radially inwardly facing, one itn substantially the diameter of the Bottle opening corresponding clear width defining boundary surfaces against a bottle opening protruding part of the plug can be pressed radially with deformation of this plug part.

The outer surface of the cylindrical casing part is flush with the outer surface, which has the same outer diameter of the locking bead, and thus forms an elegant end of the bottle neck towards the top.

In the drawing is a preferred At.sführungbeispiel of the invention shown in a schematic manner. Show it

FIG. 2 shows a section along the section line 2 - 2 in FIG. 1.

The neck 10 of a sparkling wine bottle shown in the drawing is provided with a bottle opening 12 delimiting Radially protruding pouring bead 13 and a locking bead 20 separated from the pouring bead 18 by a circumferential groove 16. The locking bead 20 has a compared to the pouring bead 18 has a larger diameter and is upward from a frustoconical annular shoulder 22 and delimited at the bottom by an essentially flat annular shoulder 24.

The bottle is fitted with an elastic stopper 26, preferably made of cork, inserted into the bottle opening. closed, one end of which protrudes slightly beyond the bottle opening 12. Next will be the bottle opening 12 and the plug 26 overlapped by a cap 28 which with its cylindrical shell part 30 un '- it is more elastic Bias is pushed over the pouring bead 18 and with its chamfered opening edge 32 against the frustoconical Shoulder 22 of the locking bead 20 abuts.

The wall thickness of the cylindrical shell part 30 corresponds essentially to the difference in the outer radii of the two Bulges 18, 20 so that there is a smooth, aligned transition between the outer surface of the cap and the outer surface of the Arretierungswulsts 20 results. To achieve a certain form fit in the area behind the pouring bead, the on its outer surface cylindrical jacket part above the opening edge 32 and increasing towards the opening edge Wall thickness and thus a slight narrowing of the opening cross-section.

In the interior of the cap 28 there are four ribs 34 opposite one another in pairs and at equal angular distances from one another

Anfoint, whose in the area of the cylindrical part of the title axially symmetrically aligned boundary surfaces 36 in pairs have a distance from one another substantially corresponding to the diameter of the bottle opening 12 and against the protruding over the bottle opening 12, something in this area opposite the bottle opening The widened end of the plug 26 is pressed and clamped by a certain elastic deformation of the plug end are.

At their other end, the ribs 34 are star-shaped on one in the area of the cap dome 40 axially symmetrically arranged Ringripp-2 molded. This arrangement of the ribs 34, 42 gives the cap 28 in spite of the elastic plastic used. materials have sufficient rigidity that a deformation in the hollow, protruding over the bottle The cap part prevents and still a secure fit on the pouring bead 18 and the protruding end of the stopper guaranteed.

When the stopper 26 is pulled out, the cap 28 can also be used alone as a bottle closure, which the Build-up of a real overpressure in the bottle is allowed and thus an escape of carbonic acid from the bottle prevented.

summary

Closing device for ratchets

The closure device is intended for sparkling wine bottles which have a radially delimiting the bottle opening A pouring bead protruding beyond the bottle neck and a radial pouring bead separated from the pouring bead by a circumferential groove Contain a locking bead protruding beyond the bottle neck and having a larger outer diameter than the pouring bead. It contains one in the bottle opening insertable stopper, preferably made of cork, and a cap that extends over the bottle opening. Around To enable the uncorked bottle to be closed again, the cap is a molded plastic part that is separate from the stopper formed with a cylindrical shell part open on one side under elastic pretension on the pouring bead can be pushed up to the stop of its opening edge against the upper annular shoulder of the locking bead. the The wall thickness of the cylindrical shell part essentially corresponds to the difference in the outer radii of the two Bulges so that there is a smooth, flush transition between the cap outer surface and the outer surface of the arresting bead results. (Fig. 1).
