Drinks bottle

The invention relates to a beverage bottle for placing on a beverage dispensing device, having a bottle wall, a bottle base and a bottle neck provided with a bottle closure, wherein the beverage bottle is intended to be placed upside down on the beverage dispensing device.

In recent times, beverage dispensing devices have become popular which have a column-like dispensing unit which has a dispensing device with at least one, usually two dispensing valves in a recess in the housing of the dispensing unit (cf. EP 0 581 491 B1; EP 0 581 492 B1). In the area of the top of the dispensing unit there is a coupling nozzle which has a raised removal mandrel in the middle. The neck of a beverage bottle which contains a drinkable liquid, usually water, can be inserted headfirst into this coupling nozzle. During the insertion process, the removal mandrel pushes open the closure in the neck of the beverage bottle so that the liquid contained therein flows into the dispensing unit via the coupling nozzle.

There are dispensing lines through which the liquid is transported to the dispensing point.

In order for the liquid to flow out of the drinks bottle, the drinks bottle must be ventilated. In the prior art, a ventilation device is provided for this purpose, which is arranged in the dispensing unit and has an outward-going ventilation channel in which a non-return valve and a filter are arranged. The ventilation channel runs through the extraction mandrel parallel to the extraction channel and opens at the tip of the extraction mandrel (EP 0 581 491 Bl). When liquid is extracted, air can flow through the ventilation channel, with the air in the liquid rising to form bubbles. If no liquid is extracted, the non-return valve prevents the liquid from flowing out through the ventilation channel. The filter in the ventilation channel is intended to prevent impurities and germs from the air from entering and thus contamination of the liquid in the drinks bottle.

For hygiene reasons, the ventilation devices in the known beverage dispensers must be cleaned on site at regular intervals - usually when the beverage bottle is replaced - or completely replaced, with the replaced parts being discarded (EP 0 581 492 Bl). This can only be done by trained personnel who must also work with protective gloves. Nevertheless, contamination can occur even with careful work. In addition, cleaning

Cleaning or replacing the ventilation system is time-consuming and costly.

The invention is therefore based on the object of reducing the maintenance effort regarding the ventilation device.

This object is achieved according to the invention in that the drinks bottle has a ventilation device which allows air to flow into the interior of the drinks bottle when liquid flows out of the drinks bottle. The basic idea of the invention is therefore to assign the ventilation device to the drinks bottle so that it is replaced when the drinks bottle is replaced. It can then be cleaned or replaced at a central collection point for the drinks bottles, where they have to be cleaned and sterilized anyway. In addition, time is saved during the replacement process.

The ventilation device can be installed at various points on the drinks bottle. It is possible to integrate the ventilation device into the bottle cap. This has the advantage that no changes need to be made to the walls of the drinks bottle and existing drinks bottles can also be equipped with a ventilation device. The integration is best done in such a way that there is a ventilation channel that has its air inlet in the bottle cap. It can end directly on the inside of the bottle cap.

This has the disadvantage, which is also the case with known beverage dispensers, that the incoming air mixes with the water, which can lead to contamination of the water despite a filter in the aeration device. In addition, the liquid pressure on the non-return valve and the elasticity of the wall of the drinks bottle lead to unsteady or intermittent air inflows, which also means that the liquid is not drawn off evenly. It is therefore more practical to extend the aeration channel preferably to near the bottom of the bottle, either by means of a ventilation pipe running through the drinks bottle or by means of a ventilation channel running on or in the bottle wall itself. By extending the aeration channel with an air outlet above the liquid level, the liquid pressure no longer presses on the non-return valve and the air flows directly into the air bubble between the bottom of the bottle and the liquid level. This means that air and liquid no longer mix, and unsteady air and liquid flows are also avoided.

Alternatively, the ventilation device can be installed in the bottle jacket - and there conveniently near the bottle bottom - or in the bottle bottom itself. This has the advantage that the bottle closure can be designed simply. The ventilation device can also be designed to be compact and easy to replace. It is possible to insert the ventilation device in a removable manner, for example.

wise screwed into a thread. A sealing threaded plug can be inserted into the thread for transport. After placing the drinks bottle on the dispensing unit, the threaded plug can then be replaced by the ventilation device. Since the ventilation device is above the liquid level, a check valve is not required. It then only has a filter. For this reason, the ventilation device has a simple structure and can be discarded instead of being cleaned.

Of course, it is possible to equip the ventilation device with a non-return valve in a conventional manner in order to prevent liquid from flowing out through the ventilation channel even if the position of the drinks bottle changes. If the ventilation device opens below the liquid level, the non-return valve is necessary to prevent liquid from flowing out.

According to a further feature of the invention, it is provided that the ventilation device is closed with a pierceable membrane, whereby the membrane is preferably arranged on the inside of the ventilation device and thus protects the ventilation device from the ingress of liquid during transport. After inserting the bottle into the dispensing unit, the membrane is pierced, which makes it possible to ventilate the beverage bottle. The piercing can be done in a simple manner with the help of a mandrel which is attached to the ventilation device.

device, whereby the mandrel and membrane can be moved relative to one another from the outside so that the mandrel penetrates the membrane. This can be done easily with the help of a stamp that can be pressed in from the outside. The mandrel can be molded onto the stamp. However, it is also possible to provide a ventilation channel through the stamp, which is then closed by the membrane, whereby the mandrel is fixed in place relative to the inside of the membrane. By pushing in the stamp, the membrane is moved against the mandrel and penetrated. The filter and, if necessary, the check valve can then also be arranged in the stamp.

The ventilation device can have a sleeve into which a ventilation body is axially displaceably inserted, which is provided with an air inlet and accessible from the outside, whereby the ventilation body has a ventilation outlet which can be revealed by axially displacing the ventilation body inwards. For transport, the ventilation body is only pushed into the sleeve so far that the air outlet is still blocked, i.e. no liquid can enter the ventilation body. The ventilation body can contain the filter and, if necessary, the check valve. After inserting the bottle into the dispensing unit, the ventilation body can then be pushed further inwards, whereby the air outlet is connected to the interior of the beverage bottle and ventilation is thus possible. In concrete terms, this can be done by placing the air outlet on the side of the ventilation next to the sleeve.

ventilation body and that the sleeve has a sealing ring that rests on the ventilation body, with the air outlet initially on the side of the sealing ring facing away from the interior of the drinks bottle and, after the ventilation body has been pushed inwards, on the side of the sealing ring facing the interior of the drinks bottle. The sealing ring can consist of one or more sealing ribs that surround the ventilation body in a ring shape. Towards the outside of the drinks bottle, further sealing rings can be provided either on the ventilation body or on the sleeve.

According to a further feature, the ventilation body does not protrude beyond the outside of the drinks bottle in the position in which the air outlet is closed, although a recessed arrangement is also useful. In this way, the ventilation body is prevented from being pressed in when the drinks bottle is knocked or placed on the bottom of the bottle. The ventilation body can be provided with a handle by which it can be moved outwards again in order to close the ventilation device again or to replace the ventilation body. The handle should be foldable so that it does not protrude beyond the outer contour of the drinks bottle.

The invention is illustrated in more detail using an embodiment in the drawing. They show:

Figure 1 is a vertical section through the lower part of a beverage bottle for a beverage dispensing device;

Figure 2 shows a vertical section through a beverage dispensing device with the beverage bottle according to Figure 1;

Figure 3 shows a vertical section through a second beverage bottle;

Figure 4 shows a vertical section through a third beverage bottle;

Figure 5 is an enlarged view of the ventilation device of the beverage bottle according to Figure 4.

Only the lower part of the drinks bottle 1 shown in Figure 1 can be seen, whereby the drinks bottle 1 is already shown in the inverted position. During transport, the drinks bottle 1 stands on its base (not shown here), so that the lower part shown here protrudes upwards.

The drinks bottle 1 has a substantially cylindrical bottle jacket 2, which merges into a truncated cone-shaped bottle shoulder 3 and a cylindrical bottle neck 4 that adjoins it. The bottle jacket 2 and bottle shoulder 3 are made of transparent plastic. The drinks bottle 1 usually contains 19 liters of drinkable liquid.

♦· ·

A bottle closure 5 is inserted into the bottle neck 4. It has a closure sleeve 6 which rests on the outside via sealing ribs - designated 7 for example - on the sealing side of the bottle neck 4. On the underside, the closure sleeve 6 has a collar 8 which fits into an annular groove 9 of the bottle neck 4, whereby the closure sleeve 6 is fixed axially relative to the closure sleeve 6.

A sealing stamp 10 extends into the closure sleeve 6. The sealing stamp 10 has a cylindrical basic shape and has four sealing ribs on top of each other in the upper area - designated 11 for example - via which it seals against the inner wall of the closure sleeve 6 in the position shown. The closure sleeve 6 is conically widened upwards in this area. So that all sealing ribs 11 can rest against the inside of the closure sleeve 6, the diameters of the sealing ribs 11 increase accordingly towards the top.

A collapsible bellows 12 is connected to the bottom of the bottle neck 4 and ends in a cylindrical end sleeve 13 from which the lower end of the closure stamp 10 protrudes. Between the bellows 12 and the end sleeve 13 there is a shoulder 14, above which a conical ring web 15 extends outwards from the closure stamp 10. The end sleeve 13 lies sealingly against the outside of the closure stamp 10.

^: i'

A dispensing hose 16 is connected to an opening in the shoulder 14. It is in open connection with the space delimited by the bellows 12 and the closure plunger 10.

The closure stamp 10 not only serves to close the drinks bottle 1, but also contains a ventilation device. For this purpose, the closure stamp 10 is hollow on the inside, i.e. it is designed as a sleeve. A filter 17 is arranged in the closure stamp 10 and is held in position at the bottom by a plug 18 that is permeable to air. Above the filter 17 there is another plug 19 that is also permeable to air and on which a non-return valve 20 (not shown in detail here) is supported. The non-return valve 20 is designed in such a way that it does not allow any liquid to pass through from above, but allows air to flow up from below.

The upper opening of the closure plunger 10 is closed with a barrier membrane 21. It can consist of a plastic film or a metal paper. Opposite the outside of the barrier membrane 21 there is a piercing mandrel 22, which is part of an insert 23 which is inserted into the closure sleeve 6 and held therein and has openings in the axial direction for the flow of liquid and the flow of air.

On the lower end of the dispensing hose 16 there is a clamp 24 which is arranged in opposing, rounded

Clamping jaws 25, 26. The clamping jaws 25, 26 press the dispensing hose 16 together so that it is closed at this point. In addition, the dispensing hose 16 can be welded shut at the lower end or provided with a cap. It can be opened by cutting off the end of the dispensing hose 16 or by removing the cap.

The clamping jaws 25, 26 are pressed together on both sides by a U-shaped spring clip 27, the respective ends of which rest on the outer sides of both clamping jaws 25, 26. They have an inherent tension that presses the ends of the spring clips 27 towards each other and thus the clamping jaws 25, 26 onto each other.

The clamping jaws 25, 26 continue into stepped actuating levers 29, 30, which are connected at the ends via flexible joints 31, 32 to joint webs 33, 34 directed towards one another. Their ends facing one another are also coupled via a flexible joint 35. The joint webs 33, 34 leave an opening free through which the dispensing hose 16 is inserted.

In the area where the clamping jaws 25, 26 are connected to the respective operating levers 29 and 30, the operating levers 29, 30 have joint stamps 37, 38 on both sides which are directed towards one another and which, in the position shown, are only a short distance apart or are in contact with one another. If pressure is exerted on the operating levers 29, 30 directed towards one another, i.e. if one tries to press them together, the joint stamps 37, 38

as a bearing and thus as a joint with the result that the clamping jaws 25, 26 are spread against the action of the spring clips 27.

The beverage dispenser 41 shown in Figure 2 has a dispensing unit 42 which has a housing 43, of which the front wall 44 can be seen partially and one of the side walls 45. The housing 43 is open towards the rear.

In the upper area, the dispensing unit 42 has a sleeve-shaped bottle coupling 46 into which the beverage bottle 1 with its bottle cap 5 is inserted. The bottle coupling 46 is surrounded by a truncated cone-shaped cooling collar 47, which is constructed from a spirally wound cooling line 48 and has a short cylindrical section extending from the bottle coupling 46 and an adjoining conical section. The cooling collar 47 is surrounded on the outside by a collar housing 49. The cooling collar 47 is shaped in such a way that the beverage bottle 1 rests with its bottle shoulder 3 on all turns of the cooling line 48.

In the lower area of the output unit 42, a compressor 50 is arranged, from which a condenser 51 extends - only partially visible due to the sectional view. A gaseous coolant is fed from the compressor 50 into the condenser 51 and liquefied there. The coolant passes from the upper end of the condenser 51

·· t

to a throttle element (not shown in detail here) which ensures such a pressure drop that the coolant evaporates. The evaporated coolant then flows into the cooling line 48 of the cooling collar 47 and there ensures the cooling of the bottle shoulder 3 and thus the liquid in the drinks bottle 1. The coolant is fed back to the compressor 50 via a return line (not shown in detail here).

In the upper part of the housing 43 of the dispensing unit 42 there is a stop plate on which the shoulder 14 sits between the bellows 12 and the end sleeve 13. The stop plate 52 is mounted at such a height that the bellows 12 is compressed when the drinks bottle 1 is inserted and the bottle cap 5 is introduced into the bottle coupling 46 by placing the shoulder 14 on the stop plate 52. The shoulder 14 thereby displaces the closure stamp 10 upwards over its ring web 15. This has two consequences.

Firstly, the sealing ribs 11 on the closure plunger 10 lift off the conical inside of the closure sleeve 6, so that the bottle closure 5 is opened. In this way, liquid from the drinks bottle 1 between the closure sleeve 6 and the closure plunger 10 can flow downwards into the space delimited by the bellows 12 and the closure plunger 10 and from there into the dispensing hose 16, whereby the clamp 24 ensures that no liquid can escape from the dispensing hose 16.

On the other hand, the barrier membrane 21 moves against the piercing mandrel 22, so that the barrier membrane 21 is torn open by the piercing mandrel 22. The liquid in the beverage bottle 1 thus penetrates into the closure plunger 10, but is prevented from leaking out by the check valve 20.

When the drinks bottle 1 is placed on the dispensing unit 42, the dispensing hose 16 also reaches the interior of the housing 43. There it is guided by a guide wall 53 so that it is bent into the shape of a swan neck. The guide wall 53 ends in a clamp holder 54 which is adapted to the external shape of the clamp 24 so that the clamp 24 is held in a defined position. The dispensing hose 16 runs vertically in this area and ends in a housing opening 55 in the area of a housing recess 56 which serves as a dispensing point. The housing recess 56 has a horizontal base 57 which is dimensioned so that a cup can be placed in the housing recess 56 below the outlet opening of the dispensing hose 16. The outlet opening of the dispensing hose 16 and the housing opening 55 should be coordinated with each other as described in DE 201 19 454 U so that the dispensing hose 16 cannot come into contact with a person dispensing liquid.

An actuating piston 58 is mounted in the housing 43 so that it can be moved horizontally. The actuating piston 58

protrudes outwards and rests with its inner end on the adjacent actuating lever 29. If pressure is exerted on the actuating plunger 58, the actuating levers 29, 30 are moved against one another, which results in the clamping jaws 25, 26 being spread apart. The dispensing hose 16 can expand elastically so that liquid can flow out of the dispensing hose 16.

As the liquid flows out of the dispensing hose 16 and thus the drinks bottle 1, a negative pressure is created in the drinks bottle 1. This opens the check valve 20 so that air flows into the drinks bottle 1 via the stopper 18, the filter 17, the stopper 19, the check valve 20 and the insert 23 and compensates for the loss of volume caused by the dispensed liquid. When the actuating piston 58 is relieved again, the dispensing hose 16 is closed again by the clamping jaws 25, 26, which are pressed against one another by the spring arches 27. The check valve 20 ensures that no liquid can escape via the ventilation device after the pressure has been equalized.

To replace the drinks bottle 1, it is only necessary to lift it upwards. The dispensing hose 16 is taken along with the clamp 24. A new drinks bottle with the associated dispensing hose can then be inserted in the manner described above. The old drinks bottle 1 is transported to a central location, cleaned and refilled. It depends on the costs

whether the dispensing hose 16 is also cleaned or replaced with a fresh one.

Figure 3 shows a second drinks bottle 61, which in its basic form corresponds to the drinks bottle 1 as shown in Figures 1 and 2. It is also shown in the already turned inside out position. It has a substantially cylindrical bottle jacket 62, which merges into a truncated cone-shaped bottle shoulder 63 and a cylindrical bottle neck 64, which is connected to this and on which a bottle closure 65 is located. It has an opening 66 in which a bottle valve is normally inserted. In this view, the drinks bottle 61 has a bottle base 67 on the top, on which the drinks bottle 61 stands during transport. The drinks bottle 1 is made of a transparent plastic material.

The beverage bottle 1 has a ventilation device 68. This has a straight ventilation tube 69, which is held in the region of its lower end on the bottle closure 65. It protrudes downwards from the bottle closure 65 and has an air inlet 70 there. It passes through the beverage bottle 61 up to the vicinity of the bottle bottom 67 and has an air outlet 71 there.

In the lower part of the ventilation pipe 69, a filter 72 is inserted and above it a check valve 73 designed as a ball valve. The check valve 73 prevents liquid that escapes via the air outlet 71

penetrates the ventilation pipe 69, flows outwards, and it protects the filter 72 from contact with the liquid. Conversely, the check valve 73 allows air to flow through the air inlet 70, the ventilation pipe 69 and the air outlet 71 into the upper area of the beverage bottle 61 in this view when liquid is removed from the beverage bottle 1, thus replacing the drawn-off volume of liquid, so that the outflow of the liquid is not hindered by the formation of a vacuum.

Figure 4 shows another beverage bottle 81 which has the same shape as the beverage bottle 61 according to Figure 3 and is also shown in the inverted position. It has a substantially cylindrical bottle jacket 82 which merges into a truncated cone-shaped bottle shoulder 83 and a cylindrical bottle neck 84 which is connected to it. The bottle cap is omitted here. At the opposite end, the beverage bottle 81 has a bottle base 85.

A ventilation device 86 is inserted into the bottle base 85. It is shown enlarged in Figure 4. The bottle base 85 has in this area an annular, stepped recess 87 into which a sleeve 88 is inserted, which has a cylindrical sleeve jacket 89 projecting inwards into the beverage bottle 61 and a flange 90 on the outside with which it rests on the recess 87.

Inserted into the sleeve 88 from the outside is a substantially hat-shaped ventilation body 91, which has an annular web 92 on the outside, which partially overlaps the flange 90 of the sleeve 88. On the inside, the ventilation body 91 has a closed bottom 93. A filter 94 is inserted into the ventilation body 91. On the outside, the ventilation body 91 is closed off by a hat-shaped insert 95. A semicircular handle 96 is hinged to the insert 95, which is laid flat but can be raised by 90°. With the help of this handle 96, the ventilation body 91 can be pulled out of the sleeve 88. The insert 95 has a series of openings 97 forming the air inlet. Near the bottom 93, the ventilation body 91 has a hole which forms the air outlet 98.

The ventilation body 91 has two sealing rings 99, 100 in the middle area, which seal against the inside of the sleeve casing 89. Conversely, the sleeve casing 89 has an inwardly projecting sealing ring 101 in the area of its lower end, which is intended for sealing against the ventilation body 91.

In Figure 4, the ventilation body 91 is only partially inserted into the sleeve 88, so that it projects outward beyond the base 93 and the base 93 is still located above the sealing ring 101. For transporting the beverage bottle 81, the ventilation body 91 is pressed into the position shown in Figure 5.

In this position, the ring web 92 and the handle 96 are recessed relative to the outside of the bottle base 85. However, the ring web 92 is still at a distance from the flange 90, and the air outlet 98 is still located on the side of the sealing ring 101 facing away from the interior of the beverage bottle 81. In this way, the liquid in the beverage bottle 81 cannot penetrate into the ventilation unit 86.

As soon as the drinks bottle 81 is inserted into the drinks dispenser, the ventilation body 91 is pressed further into the sleeve 88 until the ring web 92 comes to rest on the flange 90. As a result, the air outlet 98 passes the sealing ring 101 and comes to rest below this sealing ring 101. When liquid is removed from the drinks bottle 81, air then flows through the openings 97, the filter 94 and the air outlet 98 into the interior of the drinks bottle 81 and ensures pressure equalization there. Since the drinks bottle 81 is held in a vertical position in the drinks dispenser, the liquid level is below the ventilation device 86 so that no liquid can penetrate. Therefore, a check valve is not required with this type of ventilation device 86.

When cleaning the beverage bottle 81 after it has been emptied and transported to a cleaning station, the aeration body 91 can be pulled out again using the handle 96 and either discarded or cleaned.

, whereby the filter 94 is replaced. When the ventilation body 91 is removed, the beverage bottle 81 can also be filled with fresh liquid via the sleeve 88.
