The leg parts on each side of the wire hanger have eyelets bent at right angles, the eyelet of each leg part encompassing the respective lengthening leg part on the same side of the wire hanger, with a compression spring being arranged between the opposite eyelets on each side of the wire hanger through which the closure piece is pulled against the bottle opening to ensure a tight seal.

A clip closure known from the prior art for a bottle, in particular a beer bottle, comprises an essentially U-shaped clip, on the web of which connecting two mutually spaced legs a closure piece carrying a seal is arranged. The two legs have hook-shaped bends at their free ends which engage in eyelets of a handle, the eyelets being formed by reshaping the handle and the handle merging into fastening hooks which extend essentially perpendicular to the handle. When mounted on the bottle, the fastening hooks grip into side openings in the bottle neck and both the handle and the bracket with the closure piece can move freely. To close the bottle, the closure piece with its seal is placed on the opening of the bottle and the handle is pivoted in a direction facing away from the opening in such a way that it comes to rest on the periphery of the bottle neck and the closure piece rests on the opening under pretension due to the dimensions of the swing top . Due to the bias, the opening of the bottle is sealed gas-tight.

Small brewers who brew beer primarily for private use often have the problem that after the relatively simple brewing process when bottling after fermentation in a fermentation barrel, not the required amount of carbonic acid is added, but the carbonic acid is added to the remaining sugar must form. The measurement of the CO2 content or the residual sugar content can either be done with relatively expensive measuring devices that are not worth buying for the private brewer, or only imprecisely.

In a frequently used method, a previously calculated amount of the brew, the so-called wort, is branched off and frozen after the brewing process. The diverted amount, the so-called food, is calculated based on the desired CO2 content, the total amount and the existing sugar content using formulas and tables. The beer is then completely fermented in the fermentation barrel until fermentation comes to a standstill. The food is then thawed, the temperature of the food is adjusted and the food is mixed with the fermented beer in the fermentation barrel. Finally, the beer can be bottled. If the right amount of food has been determined, the bottled beer should start fermenting again and the desired CO2 content should be created in the bottle. This method is disadvantageous insofar as it is associated with a great deal of work and time and, due to calculation errors, there is a risk that the second fermentation phase of the beer no longer begins or is not fully carried out, making the end product inedible.

With a further method, the so-called green hose, the filling time is recognized by the brewer's foam formation with a lot of experience. This method is relatively unproblematic when filling a barrel, since a bunging device is known for barrels, which releases the pressure created by the carbon dioxide produced, a corresponding limit pressure being adjustable on the bunging device. This limit pressure, which is directly related to the carbon dioxide content of the beer, is relatively easy to determine in a table. Since this method of the basic hose can be carried out relatively easily, it is desirable for private hobby brewers to make this method applicable to bottling beer by means of an inexpensive device.

The invention is based on the object of creating a clip closure of the type mentioned at the outset, on which, with a simple and inexpensive construction, an opening pressure can be set which ensures fluid escape from a bottle closed with the clip closure.

According to the invention, the object is achieved by the features of the independent claim.

The subclaims represent advantageous embodiments of the invention.

A clip closure for an opening of a bottle, in particular a beer bottle, comprises a U-shaped clip, on whose web connecting two spaced-apart legs a closure piece with a sealing surface is arranged on at least one bottle neck, the two legs having hook-shaped bends at their free ends that engage in eyelets of a handle that merges into fastening hooks, the handle being pivotable from an open to a closed position. A wire clip of an adjusting device or spring device that can be placed circumferentially against a bottle neck is hooked into the eyelets of the handle, with the adjusting device or spring device being supported with one end on the peripheral side of the bottle neck in a position of use mounted on the bottle and pretensioning the handle in the direction of the bottle . The clear distance between the sealing surface and the fastening hooks can be changed by means of an adjusting device and the closure piece interacts with an adjustable spring device which is effective with respect to the web of the bracket.

In this embodiment of the invention, the clip closure is not closed with the handle resting on the bottle neck in such a way that the closure piece with its sealing surface is pretensioned in a sealing manner on the free end of the bottle neck to close the opening. Rather, by means of the adjusting device or spring device supported on the circumferential side of the bottle neck, the handle is pulled in the direction of the bottle neck, i.e. into the actual locking position, with a defined tensile stress being exerted on the locking piece with its sealing surface, which allows the in the Bottle located fluid with the achievement of a certain pressure allows.

Because the clear distance between the sealing surface of the closure piece and the fastening hook is adjustable, the pressure with which the closure piece is held on the opening of the vessel can also be adjusted. Alternatively, the closure piece is provided with the adjustable spring device, the spring device ensuring the required contact pressure of the closure piece or the sealing surface on the opening of the vessel. Due to the adjustability of the spring device, different pressures can be set in order to ensure that carbonic acid can escape from the vessel at a certain limit pressure.

A common feature of the clip closures according to the invention is that the pressure is selected in accordance with the requirements, for example as a function of the ripening temperature of the beer present in the vessel or bottle. The closure piece, appropriately preloaded by means of one of the adjusting devices or spring devices, acts like a bung valve used in a barrel and ensures that the carbonic acid that forms during fermentation escapes when a certain pressure is reached. This method of escaping CO2 from the otherwise closed vessel corresponds to the so-called green hoses when brewing beer.

The clip closures according to the invention ensure that, on the one hand, a closed bottle is not opened unintentionally by a relatively high internal pressure and, on the other hand, the closure piece is tightly closed until the pressure set on the actuating device and / or the spring device is reached, which is empirically determined .

For example, the brewer's yeast used in the production of top-fermenting wheat beer requires a fermentation temperature of about 22 ° C and, with a desired CO2 content of 5 g / l, a plug pressure of 2.2 bar to be set on the closure piece is required. Brewer's yeast is used for bottom-fermented Pilsen beer, which requires a fermentation temperature of around 12 ° C. If a CO2 content of 5 g / l is required, a bung pressure of 1.4 bar to be set on the closure piece is required.

Since a large number of types of beer and yeast are known and the CO2 content in the drink is selected depending on the taste of the consumer, it is necessary to dimension the actuating device or spring device so that at least a plug pressure between 0.8 bar and 3 bar is adjustable on the adjusting device or spring device, so that the carbon dioxide can escape from the bottle at a pressure above the set pressure, since the sealing surface of the closure piece is lifted at least partially from the opening of the vessel to be closed. Of course, the bottle is tightly closed below the set or selected plug pressure, since the sealing surface is pressed onto the opening of the bottle neck in a pretensioned manner when the handle of the closure piece is approached to the vessel in order to close it.

The clip closure can be removed from the associated vessel in a few simple steps and cleaned after its relatively simple dismantling, for example in one commercially available dishwasher, which is why reuse is possible.

In one embodiment, the adjusting device has a plurality of grooves of different lengths opening into a central opening, the length of the groove defining the pretensioning of the handle or the clear distance between the sealing surface and the fastening hooks. With an identical design of the wire bracket assigned to the adjusting device, the handle is pulled close to the bottle neck and the closure piece is pressed against the opening of the bottle with relatively high force, whereas this contact pressure of the closure piece decreases with increasing length of the groove. In an alternative embodiment, the bottle attachments of the closure piece are arranged in the manner of a revolver drum and are selected as required. Due to the different lengths of the grooves, different distances are set between the sealing surface of the respective bottle neck and the fastening hook and thus different pressures are achieved with which the sealing surface of the closure piece is held on the opening of the vessel. Each of the grooves, which are of different lengths, can be assigned a bung pressure which, when reached, causes CO2 to escape from the otherwise closed vessel.

The grooves are expediently aligned in a star shape with the opening. Accordingly, the bottle necks with the sealing surfaces are also arranged in a star shape, that is, they extend outward in the radial direction starting from the center of the closure piece. The web of the bracket is located in the opening of the adjusting device and is inserted into one of the grooves, if necessary, to close the bottle or the opening. After the sealing surface of the bottle neck has been placed on the opening, the handle is pivoted and the vessel or its opening is closed with a pretensioning predetermined by the length of the groove.

If the adjusting device engages the periphery of the bottle neck, the handle is pulled in the direction of the bottle neck by the wire clip that engages in the eyelets of the handle and protrudes through the opening of the adjusting device, as soon as the adjusting device is intended to rest on the side of the bottle neck opposite the handle. The tensile force exerted is determined by the length of the groove in which the wire clip rests, whereby the clip lock is first completely closed, then the wire clip is inserted into the desired groove and the adjusting device is brought into contact with the bottle neck and the handle is then pivoted to open the clip lock becomes.

When the preset pressure is reached, fluid, in particular CO2, can escape from the interior of the vessel. To remove the contents, the handle is pivoted and, if necessary, the adjusting device is loosened or removed in order to space the sealing surface of the bottle neck from the opening of the vessel.

In an alternative embodiment, the wire bracket or the locking piece is assigned an adjusting screw of the adjusting device that interacts with the web of the bracket and is arranged in a slot for the wire bracket or the web-having receptacle and outside the receptacle with an adjusting nut that is captive in the receptacle for axial displacement cooperates. The wire bracket or the web of the bracket is expediently inserted into an elongated hole in the adjusting screw. By means of the adjusting screw, the handle or the closure piece with its sealing surface can be pressed more or less strongly against the bottle neck in order to close its opening. By turning the adjusting screw by means of the adjusting nut, the possible distance between the handle and the bottle neck or the sealing surface of the closure piece and the fastening hook to be fixed on the bottle, in particular in the openings of a bottle neck, is changed and the contact pressure of the preferably elastic seal is adjusted in such a way that the pressurized gas present in the bottle, which in particular comprises carbonic acid, can escape when the preset pressure is reached without damaging or destroying the bottle or the swing top. So that the clip lock can be dismantled and cleaned, the wire clip or the web of the clip can be removed in the elongated hole of the receptacle that extends in the axial direction.

In a further alternative or additional embodiment, the spring device comprises a housing with an elongated hole, which is arranged on the wire bracket or the web of the bracket, a compression spring supported on the one hand on the web and on the other hand on a threaded pin being arranged in the housing having an internal thread. The pre-tensioning of the compression spring is changed by means of the threaded pin and the pressure at which the sealing surface of the closure piece releases the opening of the vessel for the carbon dioxide to escape from the interior of the vessel into the environment is thus set. The compression spring and the adjusting screw determine the so-called bung pressure accordingly.

The tubular housing expediently has a concave contact surface or the closure piece or is connected to the end face facing away from or facing the elongated hole Closure piece connected. The housing and the contact surface or the closure piece can be designed in one piece or in several parts without departing from the scope of the invention. Depending on the position of the closure piece in relation to the elongated hole, the adjusting screw is accessible or covered when the bottle is closed. If the set screw is covered by the contact surface resting on the bottle neck or by the closure piece, the bottle must be opened and the clip cap folded down using the set screw before the bung pressure is set.

In order to be able to adjust the adjusting screw with a tool, such as a screwdriver, without dismantling the closure piece, the contact surface or the closure piece preferably has a coaxial bore.

The contact surface or the closure piece is expediently designed to be elastically sealing or equipped with an elastic seal.

According to a further development, the seal is cup-shaped with a circumferential shoulder, an adjoining peripheral wall and a base closing the peripheral wall. The seal has a relatively large surface area and there are no transitions between the bottle neck and the area which usually comes into contact with the contents of the vessel. The seal and the closure piece carrying the seal are therefore relatively easy to clean.

It goes without saying that the features mentioned above and still to be explained below can be used not only in the respectively specified combination, but also in other combinations. The scope of the invention is defined only by the claims.

The invention is explained in more detail below using a number of exemplary embodiments with reference to the associated drawing.

By pivoting the handle 8th in a first position it is on the opening of the bottle 32 attached closure piece 5 sealingly pressed onto the opening and by pivoting the handle 8th in a second position the locking piece 5 to open the bottle 32 released from the opening.

To the pressure at the fluid from inside the bottle between a sealing surface 10 of the locking piece 5 and the opening of the bottle escapes, to vary, or to adjust, is in a first embodiment according to the 1 and 2 an adjusting device 11 provided that a substantially disk-shaped support part 27 includes, which extends in a star shape in different lengths from a central opening 26th extending grooves 25th having, in the opening 26th and thus also in the grooves 25th a wire hanger 36 is arranged, the free hook-shaped ends in the eyelets 7th the handle 8th intervention. The carrier part 27 the control device 11 can contact surfaces on its outer circumference 35 have, in a position of use on the bottle neck 33 issue.

For the intended use of this clip lock 1 first is the bottle 32 with the clip closure 1 locked, i.e. by pivoting the handle 8th in the first position that on the opening of the bottle 32 attached closure piece 5 sealingly pressed onto the opening. Then the carrier part 27 the control device 11 twisted so that the wire hanger 36 in one of the grooves 25th rests and the carrier part 27 on the circumference of the bottle neck 33 is applied. Then the handle 8th in one direction to open the bottle 32 pivoted, but by the effective adjustment direction 11 held in such a way that the locking piece 5 under a desired preload, which depends on the length of the groove in use 25th is that bottle 32 locks. With a relatively short groove 25th is a relatively small pivot angle of the handle 8th and the associated high pressure of the locking piece 5 adjustable, with which a high CO2 content in a carbonated drink inside the bottle 32 is achievable. If a low contact pressure is to be set, a relatively long groove is required 25th for inserting the wire clip 36 selected.

In the alternative embodiment according to FIGS 3 and 4th includes the actuating device 11 the disk-shaped support part 27 of the locking piece 5 with several bottle attachments on the circumference 24 the the grooves 25th of different lengths are assigned. In the central opening 26th in which the grooves 25th end is the jetty 4th of the bracket 2 of the clip fastener 1 is recorded. The carrier part 27 carries in flight to every groove 25th a bottle neck on its peripheral circumference 24 with a sealing surface 10 . Depending on the desired maximum achievable internal pressure in that with the clip lock 1 The vessel to be closed is the neck of the bottle 24 chosen due to the length of the groove assigned to it 25th the required contact pressure on the bottle neck 33 to close the bottle 32 achieved. With a relatively short groove 25th is a relatively large distance X between the fastening hooks 9 and the sealing surface 10 and thus a high contact pressure can be set with which a high CO2 content in the carbonated drink inside the bottle 32 is achievable. If a lower contact pressure is to be set, the bottle neck is used 24 selected for closing, that of a relatively long groove 25th assigned.

With the clip lock according to the 5 to 8th includes the actuating device 11 an adjustment screw 12 that into one with opposing slots 13 provided recording 14th is used, which extends over substantially the entire length of the recording 14th extending slots 13 the one with the eyelets 7th the handle 8th of the clip fastener 1 connected wire hangers 36 is used, which also has an elongated hole 15th the set screw designed as a threaded pin 12 penetrates. The adjusting screw 12 takes hold of her the elongated hole 15th opposite end into an adjusting nut 16 with knurling on the circumference for tool-free turning, which cannot be lost in the holder 14th is stored. By turning the adjusting nut 16 there is an axial displacement of the adjusting screw 12 and thus a change in position of the wire bracket 36 relative to the free end 17th which is located on the circumference of the bottle neck 33 supportive recording 14th , making the location of the handle 8th is also changed. With the change in position of the handle 8th a change of position of the bracket is also possible 2 of the clip fastener 1 and the contact pressure of the sealing surface 10 of the locking piece 5 at the opening of the bottle 32 is changed so that a more or less large pressure inside the bottle 32 must prevail to the sealing surface 10 lift slightly from the opening to allow fluid from inside the bottle 32 can escape.

At the clip fastener 9 includes the actuating device 11 the ones with the slots 13 provided recording 14th inserted adjusting screw 12 , which extends essentially over the entire length of the recording 14th extending slots 13 the bridge 4th of the bracket 2 of the clip fastener 1 who also has an elongated hole 15th the set screw designed as a threaded pin 12 penetrates. The adjusting screw 12 works on her the elongated hole 15th opposite end with the adjusting nut 16 together that are captive in the recording 14th is stored. By turning the adjusting nut 16 there is an axial displacement of the adjusting screw 12 and thus a change in position of the bracket 2 of the clip fastener 1 relative to the free end 17th the recording 14th who have favourited the breech block 5 or a bottle neck 24 of the locking piece 5 with the assigned sealing surface 10 wearing. By changing the position of the bracket 2 of the shutter 1 becomes the contact pressure of the sealing surface 10 changed at the opening of the bottle, so that a more or less high pressure has to prevail inside the bottle to reach the sealing surface 10 lift slightly from the opening to allow fluid to escape from inside the bottle.

When using this control device 11 is first the locking piece 5 with its sealing surface 1 on the opening of the bottle 32 put on and the free end 17th the recording 14th on the circumference of the bottle neck 33 on the handle 8th opposite side brought to the plant.
