Such a tray opener is from the French patent No. 1 030 3 ^ 9 known. This bottle opener is the stubble puller is carried by a piston which pushes into a »tubular part supported against the bottle neck. is movable. To lift the piston is done with the help of a manually operated pump from a container into a fluid pressure chamber delimited by the piston and the tubular part pumped.

Two designs have been proposed here, but both have major disadvantages. Shall pulling out of the stopper according to the one construction with only a single pumping movement, so must to the required To apply force, the stroke of the pump must be correspondingly long, making the bottle opener extremely unwieldy. In the other construction, the pump often has to be maize in order to pump the required liquid into the pressure chamber be operated.

Both constructions have the particular disadvantage that no provision is made to return the liquid from the pressure chamber, so that when the piston is completely retracted into the tubular part, the latter can no longer be extended. Because of this, but also because of the high friction losses that occur _{Λ, it} is very doubtful whether such a bottle opener would work in practice.

It is further known from Swiss Pat. No. 373,273 a Ilaschenöffner known _s which is provided with a cannula "which is pushed by the stubble and by means of which a gas is introduced into the bottle, which expels the stubble slowly from the KLasche.

Such bottle openers have a number of disadvantages:

Since the cannula must be pointed _{5 there} is a risk of injury or damage. Furthermore, the cannula can be bent or broken off very easily. In addition, the gas entering the bottle affects the liquid "in the bottle what particular _wine's true because the commonly used propellant dissolves in the wine. Furthermore, since the space between 'the liquid and the stubble must be filled with compressed gas. there is a high consumption of fuel gas. For this reason, empty bottles may be partially substituted with such a bottle not be opened _Λ since then the be refilled with propellant space is too large., In order to achieve the required for expelling the Stoppeis pressure or the gas consumption as large _s that hereby at least a substantial Part of a cartridge filling is used up. The prices used in an increasing extent stubble plastic bottle that does not therefore ₅ because the plastic does not completely seal the cannula and therefore through the gas flows through the stubble from the bottle and the required ID i uck? Does not build up.

The most serious disadvantage, however, is that many bottles cannot cope with the pressure building up in the bottle neck withstand and explode. Since this can lead to very serious injuries, there are a large number of such bottle openers no longer permitted for sale by countries.

The invention provides a bottle opener in which all of the disadvantages mentioned are avoided. This is j in a bottle with two intermeshed and by means of a flow medium mutually displaceable parts of the at least partially delimit a pressure chamber, wherein one part at least approximately cylindrical and which projects at its one end face of a helical or spiral _a in the direction of movement of the two parts Carrying stubble puller, which is slidable into the other part, and the other part is designed to support the bottle neck ^ according to the invention achieved in that the part carrying the stubble puller is provided with a cavity, which is accessible through the end opposite the stubble puller and into which a gas cartridge and a valve can be inserted, whereby gas flows out of the gas cartridge into the pressure chamber by actuation of the valve, whereby the two parts are displaced relative to one another.

The part which is supported on the bottle neck preferably surrounds at least a part of the cavity in its starting position to hold the cartridge.

According to a preferred embodiment, the part carrying the stubble puller has an axially extending annular gap trained in which the tubular shaped other Part is guided, the two parts sealed against each other to form a pressure chamber enclosed by them are ο

On the one hand to screw in the valve and to open the cartridge and on the other hand to be able to screw in the stubble Overcoat well in a stubble _s can the bottle be associated with a handle which with professional, lierungen formed on the valve and the handle corresponding profiles and in a first position can be coupled to rotate with the valve and in a second position with the stubble puller.

When using a bottle opener according to the invention, the helical or spiral-shaped stubble puller is screwed into a stubble. Upon actuation of the valve flows out of the cartridge in the pressure chamber a gas _s shifted from each other, and said plug is pulled out of the bottle neck whereby the said two parts. Since the pressure builds up slowly in the pressure chamber, the two parts are evenly displaced against each other, thus preventing the stubble puller from tearing out of the stubble.

Such a bottle opener is like a conventional stubble puller can be handled., it is even when exhausted

of a wine, through the propellant gas.

A bottle opener according to the invention is suitable for opening partially emptied bottles and to remove leaky stubble as well as torn off champagne stubble. He can also can also be used to remove stubble made of plastic. As a result of its construction comes further an inventive bottle opener with the lowest possible amount of propellant gas. Thereby * that the gas cartridge is within the Is arranged mutually displaceable parts, an extremely space-saving structure is achieved and can therefore the Bottle openers are given a very handy shape.

With a bottle opener according to the invention can thus easily stubble of any kind from bottles while avoiding the difficulties inherent in the prior art removed. In particular, as soon as the stubble puller is screwed into the stubble »to remove the stopper No force is required from the bottle neck and the bottle opener can be operated with just one hand.

FIG. 5 shows the operating handle in the direction of arrow A in FIG. 3.

The bottle opener shown in Fig. 1 contains two parts 2 and 3 which can be displaced relative to one another by a predetermined length. Part 2 is formed by two pipe sections 2a ₃ 2b connected to one another, of which the pipe section 2b carries a helical stubble puller at its lower end. An annular gap ₃ in which the likewise tubular part 3 is guided is formed between the pipe sections 2a , 2b. In a cavity 8 of the part 2 of _S from the stubble the puller opposite front end is accessible _2, a gas cartridge 9 and a valve 10 are used. The cavity 8 is

30981 9/0219

largely adapted to the shape of the cartridge 9 to avoid unnecessary empty space. In the annular gap formed between the pipe sections 2a, 2b is through the pipe section 3> which is sealed against the part 2 by rings 6 and 7. » , are moved to the _s is introduced gas 9 from the cartridge by actuating the valve 10, which is also sealed against the part 2 by means of a sealing ring 11 causing the two parts 2 and 3 against each other, a pressure chamber 4 is formed.

The valve 10 consists of a carrier body 13 ₃ in which a plunger 15, which can be displaced by means of a push button I ^, is mounted and held by a snap ring 16. The plunger 15 is sealed off from the carrier body 13 by a sealing ring 17. In the non-pressed position of the plunger 15, a vent hole 18 arranged below this ring leads through the support body 13 to the outside. At its lower end, the plunger 15 merges into a push rod 20 provided with helical grooves. In this area, the support body 13 is provided with a radial bore 21, to which a longitudinal groove 22, likewise provided in the support body 13, adjoins " the bore 21 and the longitudinal groove 22 forming a channel leading to the cavity 8.

With the bumper 20, a ball 23 can be adjusted, which with a conical sealing surface 2 * 1 is the actual Valve forms. Below the valve is a hollow mandrel 25

309819/0219

arranged, which when screwing the valve 10 into the Cavity 8 pierces the closure of the gas cartridge 9. The gas cartridge 9 is against the valve 10 by means of the Seal 26 surrounding mandrel 25.

The tube 2a is at its upper end with a collar 28 »which serves as an upper stop for the pipe section 3. Furthermore, the pipe section 2a is at its lower end provided with a nose 30;. which in a groove 29 of the pipe section 3 protrudes. The nose 30 serves as a lower stop which prevents the pipe section 3 from being extended too far.

To the stubble puller screw 5 in a better stubble 33 ₃ of a bottle neck 34 closes _{s 3,} the part 2 may be provided in its upper portion with handles 31st

As can be seen from Fig. 2 ₃ , the part 3 does not need to be tubular, but can be designed as a ring 3 ^ at its upper end. That carries the sealing rings 6 and 7 and on the webs 36 ' _s on the bottle neck to support come _s to connect.

According to the embodiment shown in FIGS. 3 to 5, the valve 10 is formed at its upper end with an octagonal peripheral part 35 and above it with a cylindrical peripheral part 36 with a smaller diameter. _{An actuating handle 4O 1} is assigned to the valve

3 0 9 8 19/0219

which is provided with a central opening 41, the inner profile of the opening being the ac-ht-edged profile 35 corresponds.

If the valve is to be screwed into the part 2 10 for the time being, the operating handle is put in the IO ¹ shown in Fig. 3 example, on the octagonal peripheral portion 35 and twisted. As soon as the valve 10 has been screwed in sufficiently far and thus the cartridge 9 has also been opened, the actuating handle 40 comes out of engagement with the octagonal peripheral part 35 j since this has been screwed into part 2. He can then removed and. As shown in FIG. 4, they can be placed upside down on the part 2, a cylindrical surface 42 provided with a corrugation coming into engagement with the corrugation 19 provided on the circumference of the part 2. Thus, the stubble puller 5 can be screwed into a stubble by means of the operating handle 40. In this position of the actuating handle 40, the push button 14 is also released for opening the valve.

To open a bottle, the stubble puller 5 is screwed into its stubble, for example a cork 33 _{5 ,} until the bottle opener rests on the bottle neck 34. As soon as the push button 14 is pressed, the ball 23 is lifted from the sealing surface 24 and gas flows from the cartridge 9 through the hollow mandrel 25, the grooves of the bumper 2O ₅ the bore 21 and the groove 22 into the cavity 8 and out of it a hole

U. 12 into the pressure chamber once the pressure built up in the pressure chamber H pressure, the frictional force between the cork 33 and the bottle neck 34 exceeds _s is pushed out the tube piece 3 from the part 2 against the bottle neck 3 ^. The dimensions of the pipe section 3 are chosen so that the stubble _{s is} slowly pulled out of the neck of the bottle by the thrust occurring even at high pressure ^.

Since the two parts 2 _S 3 can be displaced against each other at least by the length of a stop _? is> as soon as the _part's 3 extended fully and the stubble 33 from the bottle away. In the extended position of the part 3, the stubble 33 is therefore completely within the pipe section J.

Since all the chambers and bores of the bottle opener are sealed off from the outside during the pull-out process, the gas consumption is limited to filling the pressure chamber H and the channels leading to it. After relieving the pressure on the push button I ^ the valve formed by the ball 23 and the ball seat 2k closes and the plunger 15 moves upwards again. Thus, the bore 18 is released _s, the pressure prevailing in the chambers 4 and 8 and in the connecting channels pressure thereby degrades ,, thus a pressure compensation is carried out. As a result, the pipe section 3 can be pushed into the part 2 and the cork 33 is freely accessible, whereby it can be unscrewed from the stubble puller 5. The deT bottle opener is now ready for the next use. If necessary, a radial bore can also be provided in part 2a

after the necessary shift of part 3 is released, whereby the pressure chamber is vented and the movement stroke is limited as a result.

A bottle opener according to the invention is expediently made of light metal or hard plastic. Commercially available cartridges with CO ₂ filling are preferably used as cartridges, which were developed for siphon bottles and are sufficient for 30 to 50 uses of the bottle opener according to the invention with a pressure of about 40 atm at 22 ° C.

As can be clearly seen from the above, a bottle opener is thus created which can be used regardless of the material from which the stubble is made, in which there is no risk of explosion, which can often be used with a cartridge filling but also without a cartridge * which does not require a specific bottle or stubble shape , which is functional even when the bottle is only half-filled and which, although it contains a gas cartridge as a power source, is not particularly long, so it is very handy.
