  • Such a device is for instance known from NL-A-8600111.
  • the device of NL-A-8600111 comprises a stopper with a pump connectable thereto for respectively extracting and pressing gaseous medium out of and into the bottle.

  • the screw is displaced downward such that a pouring opening connecting to the tube is situated under the cork in the inner space of the bottle.
  • a gas feed opening connecting to the gas tube is simultaneously also situated under the cork in the inner space of the bottle so that gas is fed to the bottle during pouring of wine.
  • a drawback of the device of US 4,984,711 is that pouring of the wine cannot take place in normal or natural manner, i.e. the pouring behaviour differs from the pouring behaviour of a bottle of wine not comprising such a device.
  • Known from FR 1,232,980 and DE98965 are tap devices for tapping a liquid.

  • the device is embodied such that during pouring of liquid, wherein the bottle lies at an angle suitable for pouring relative to the vertical, the poured volume of liquid is replaced by a substantially equal volume of gas from the reservoir.
  • Replacing the poured volume of liquid with gas during pouring of liquid can prevent ambient air entering the bottle via the opening in the cap. Exposure of the liquid to ambient air during pouring of liquid can hereby be prevented or at least limited. It is a particular advantage for the purpose of pouring wine in the catering sector that the wine can be poured in normal manner, i.e. when no device is provided for preventing exposure of a liquid to ambient air, while no exposure of the liquid to air takes place. This makes it possible for relatively expensive wines in

  • the pouring opening is disposed in the cap so that, in the situation where the device is mounted on a bottle, the pouring opening is located in the neck of the bottle, i.e. at the top of the bottle. This achieves that during pouring of the liquid, wherein the bottle lies at the stated angle relative to the vertical, the pouring opening is in contact with the liquid level, even when most of the liquid in the bottle has been poured. A normal pouring behaviour and a pleasant experience is hereby also achieved even as the bottle becomes emptier.
  • the angle suitable for pouring relative to the vertical depends on the quantity of liquid present in the bottle. In the case of a substantially full bottle the angle can be smaller, for instance about 90°, so that the bottle extends substantially horizontally, than in the case of a substantially empty bottle, which angle can then for instance be about 135°.

  • the angle is greater than in a bottle without device.
  • the bottles of FR 1,232,980 and DE 98965 the bottle or the canister is always vertical during the tapping.
  • Yet another advantage of the other embodiment of the device according to the invention is that the user can pour the liquid out of the bottle using only one hand, wherein the user is able with his/her one hand to hold the bottle and operate the valve for the purpose of opening the pouring opening.
  • the liquid can in this way be poured from the bottle in the same manner as with a bottle without a device of the type stated in the preamble.

  • Yet another embodiment of the device according to the invention comprises closing means for closing the medium- throughflow connection between the reservoir and the inner space, the closing means being adjustable between a closed first position and an open second position for flow of the gas into the inner space of the bottle.
  • An advantage of such closing means is that whether or not gas flows into the inner space of the bottle can be controlled in simple manner by closing or leaving clear the medium-throughflow connection between the reservoir and the inner space.
  • the closing means and the valve are preferably mutually coupled such that the closing means and the valve are situated substantially simultaneously in their first position and/or their second position.
  • Such a coupling can be a direct coupling, for instance a mechanical coupling, but also an indirect coupling, for instance an electronic coupling .

  • a device with a tube having such a length has the advantage that it can be easily arranged on bottles of different heights. Another advantage of such a tube occurs particularly when the liquid is wine. It is possible in the case of wine that sediment is present in the bottom of the bottle. It is desirable not to disperse the sediment through the liquid, which can be prevented by not allowing the tube to extend wholly to the bottom of the bottle but to the stated heights.
  • the tube is curved such that in the mounted situation of the device the end extending into the inner space of the bottle is situated close to the peripheral wall of the bottle.
  • the end of the tube extending into the inner space of the bottle is in this way situated above the liquid level during pouring, if the bottle is held correctly, thereby preventing bubbling of the liquid.

  • Displacement of the closing means between the first position and the second position preferably takes place under the influence of gravitational force.
  • Such closing means can for instance comprise a valve or other closing element, which valve or closing element, in the vertical position of the bottle, closes the tube in a zone lying between the second gas outlet opening and the gas outlet opening such that, by closing the tube in said zone, the gas outlet opening is closed while the second gas outlet opening is left clear.
  • the valve or the closing element conversely closes the opening, and the medium-throughflow connection of the tube is left clear.
  • control means can comprise a second tube extending in the tube, wherein a first end of the second tube debouches in the tube in a zone between the gas outlet opening and the second gas outlet opening.
  • the second tube has an outer diameter here which is smaller than the inner diameter of the tube such that a space through which gas can flow lies between the tube and the second tube.
  • the second gas outlet opening is situated above the first end of the second tube and the gas outlet opening is situated under the first end of the second tube such that, in the vertical position of the bottle, the gas flowing out of the second tube into the tube will displace upward between the tube and the second tube via the space through which gas can flow, and will flow through the second gas outlet opening into the neck of the bottle.

  • the gripping element with protrusion provides the advantage that a user can grip this protrusion in simple manner with for instance the index finger for the purpose of operating the handle.
  • the protrusion is preferably situated on a side of the handle facing toward the bottle such that the handle can be operated in simple manner by the index finger of the user being placed round the protrusion and the handle being displaced in the direction of the bottle by a pressure being exerted thereon with the index finger.
  • the gripping element is connected rotatably to the handle, the gripping element can be easily rotated to its correct position on the side of the handle facing toward the bottle. It is noted that, depending on the user, the correct position can also be a different position. The correct position is therefore seen here as a position which can easily be gripped by a user.
  • the gripping element rotatably connected to the handle is particularly advantageous when the handle has the above described first part and second part. It is possible in this case that the protrusion of the gripping element is not in the correct position relative to the bottle as a result of the second part of the handle being screwed onto first part, which can be easily corrected by rotating the gripping element .
  • the device comprises locking means for locking the handle in the first position.
  • the device For simple pouring of the liquid from the bottle the device comprises a spout.

The liquid will hereby flow easily and wholly out of the spout, even after the valve of the pouring opening has been displaced to its closed position.
  • An advantage of pouring completely out of the spout liquid poured from the bottle is that no liquid which can be adversely affected is left in the spout.
  • Such air supply means can for instance comprise a spout with a greater throughflow area than the pouring opening.

  • Device 1 comprises a cap 4 which is arranged on neck 5 of bottle 2 and closes the opened bottle 2.
  • Cap 4 is provided with an opening 6 with a valve 7 which is adjustable between a closed first position (see figure 2) and an open second position for pouring liquid (see figure 3) .
  • Opening 6 has an inner diameter of about 9 mm so that the throughflow area amounts to about 63 mm 2 .
  • valve 7 Opening of valve 7 to its second position takes place by displacing a handle 8 connected hingedly to cap 4 under pressure in the direction of neck 5, wherein a protrusion 9, which extends toward neck 5 from a surface of handle 8 facing toward neck 5, displaces a pressing element 10 connected to valve 7 and thus opens valve 7. Displacement of pressing element 10 also leaves clear a gas feed to the inner space of bottle 2, as will be further elucidated below. Pressing element 10 is connected to cap 4 using a spring 11 such that, after release of the pressure on handle 8, spring 11 pushes pressing element 10 outward and valve 7 is closed. Valve 7 is therefore located in its closed first position unless, preferably during pouring, a pressure is exerted on handle 8.
  • cap 4 is provided with clamping means 12 which for instance comprise an engaging surface 13.
  • Extending round clamping means 12 is a pressing cylinder 15 connected to cap 4 by means of co-acting screw means 14.
  • the thickness of the wall of pressing cylinder 15 increases in a direction away from the underside of bottle 2.
  • pressing cylinder 15 is rotated counter-clockwise, pressing cylinder 15 will displace in the direction of the underside of bottle 2, whereby clamping means 12 will displace over the surface of pressing cylinder 15 rising obliquely inward and are therefore displaced inward.
  • This increases the pressure of clamping means 12 on neck 5 of bottle 2, whereby a good attachment is provided between cap 4 and neck 5.
  • clamping means 12 are displaceable in a direction from and toward neck 5 using pressing cylinder 15, variations in the outer diameter of neck 5 can be compensated by cap 4 and a good attachment can be provided.
  • cap 4 is provided with sealing means extending on the inner side of neck 5.
  • the sealing means comprise a preferably flexible cylinder 16 with an edge 17 extending radially outward.
  • Cap 4 has at an end remote from neck 5 of bottle 2 a detachable spout 18.
  • An advantage of such a detachable spout 18 is that it can be easily detached for cleaning purposes.
  • Device 1 further comprises a reservoir 20 for a gas which does not adversely affect liquid 3.
  • the gas can for instance be an inert gas, such as nitrogen or argon, or a non-inert gas such as carbon dioxide.
  • a tube 21 is connected on one side for medium throughflow to reservoir 20 and connected on the other for medium throughflow to the inner space of bottle 2.
  • the poured volume of liquid is replaced according to the invention by a substantially equal volume of gas from reservoir 21. This replacement of the liquid by gas will be further described hereinbelow.
  • valve 7 of cap 4 takes place by inward displacement of pressing element 10 using handle 8.
  • a closing valve 23 which closes the medium- throughflow connection between reservoir 20 and bottle 2, from a closed first position to an open second position.
  • Figures 2 and 3 show that, when handle 8 is displaced inward, valve 7 of cap 4 is first displaced to its open second position and closing valve 23 is then displaced, with a short delay, to its open second position.
  • valve 7 is connected to pressing element 10 such that valve 7 is opened immediately upon displacement of pressing element 10, while closing valve 23 is then opened only at the moment the end zone of pressing element 10 facing toward closing valve 23 comes into contact with closing valve 23 and displaces closing valve 23.
  • the time duration of the short delay between opening of valve 7 and closing valve 23 is determined by the speed at which handle 8 is displaced inward and the distance between the end zone of pressing element 10 facing toward closing valve 23 and the closing valve 23 in the closed first position.
  • the pressure of the gas in tube 21 on the upstream side of closing valve 23 is roughly equal to the atmospheric pressure, whereby during pouring of liquid out of bottle 2 the gas flows out of reservoir 20 through tube 21 into the inner space of bottle 2 and so replaces the volume of liquid poured out. After pouring of liquid the pressure on handle 8 is released, whereby a spring 24 with which closing valve 23 is connected to device 1 presses closing valve 23 to its closed first position.
  • the pressure of the gas in device 1 is by way of example, though not exclusively, as follows.
  • the pressure of the gas in reservoir 20 is about 200 bar. This pressure is chosen such that sufficient gas can be stored in the relatively small volume of reservoir 20. If a greater or smaller volume is provided or, depending on the volume of the bottle, more or less gas is required, it is possible to opt for a different pressure of the gas in reservoir 20. Because the liquid would be pressed out of bottle 2 with considerable force at a pressure of 200 bar, the pressure is reduced in steps to a pressure just above or just below the atmospheric pressure. This reduction of the pressure in steps takes place using three pressure reducing valves. A first pressure reducing valve 25 reduces the pressure of the gas from 200 bar to about 10 bar.
  • the second pressure reducing valve 26 reduces the pressure from 10 bar to about 1 bar.
  • the third pressure reducing valve 27 is a choke valve and reduces the pressure to about 50 mbar.
  • the pressure of 50 mbar is the pressure of the gas at which it flows into bottle 2 for the purpose of replacing the poured volume of liquid with gas.
  • the pressure of 50 mbar is chosen such that liquid 3 flows out of bottle 2 at a speed suitable for pouring. If the pressure is too low, the outflow speed of liquid 3 is too low and if the pressure is too high, the outflow speed of liquid 3 is too high.
  • the pressure is preferably adjustable so that the outflow speed can be varied. Adjustment of the pressure can for instance take place by adapting the size of the cross-section of choke valve 27.
  • the cross-section is for instance 0.4 mm at a pressure of 50 mbar. Depending on the desired pressure, the cross-section can be increased or reduced, this resulting in respectively a greater or smaller pressure.
  • a safety valve 28 is further provided. In the case for instance a pressure reduction or closing valve 23 is not functioning properly, gas can flow therethrough out of the part of tube 21 lying downstream of closing valve 23 if the pressure in this part of tube 21 is higher than a predetermined pressure, for instance 200 mbar.
  • An indicator 29 is further provided which indicates the degree of filling of reservoir 20.
  • the length of tube 21 is chosen such that the end of tube 21 extending in the bottle extends to a position between about 1/4 and 1/3 the height of bottle 2.
  • This is particularly advantageous for wine bottles, as will now be elucidated. Particularly in the case of non-sparkling red wine it is possible that sediment is situated in the bottom of bottle 2. It is not desirable for this sediment to disperse through liquid 3 in bottle 2. In order to prevent dispersal of the sediment through liquid 3, the end of the tube is preferably not situated very close to the bottom of the bottle 2 but at the above stated height.
  • Another advantage of the chosen length is that the same tube 21 is thereby suitable for different bottles of different heights. In the case of liquids other than wine, the end of tube 21 extending in bottle 2 optionally does extend close to the bottom of bottle 2, and the length of tube 21 is chosen as such.
  • Figure 1 shows that tube 21 is curved such that the end of tube 21 extending in the bottle extends close to wall 22 of bottle 2.
  • the end of tube 21 is not situated in liquid 3 during pouring, but above the liquid surface. Bubbling of the liquid and/or dispersal of sediment is hereby prevented.
  • a non-return valve 30 Arranged at the end of tube 21 extending in bottle 2 is a non-return valve 30 which makes it possible for gas to flow out of tube 21 into the bottle during pouring of liquid 3 from bottle 2, but prevents liquid 3 flowing into tube 21.
  • Tube 21 further has a second gas outflow opening 31 for feeding gas to the inner space of bottle 2 when the bottle is in a vertical position.
  • the second gas outflow opening 31 is situated at a location of tube 21 such that it is situated in the neck 5 of bottle 2.
  • the second gas outflow opening 31 has the following advantage.
  • Handle 8 is displaced for this purpose toward neck 5 when the bottle is in its vertical position. Displacement of handle 8 opens closing valve 23 as described above, whereby gas will flow out of reservoir 20 through tube 21.
  • a spherical closing element 32 closes the end of tube 21 extending in bottle 2 when the bottle is in its vertical position, while conversely leaving the second gas outflow opening 31 clear.
  • the gas will hereby flow through the second gas outflow opening 31 into bottle 2 and press the ambient air out of bottle 2. It is advantageous in the vertical position of bottle 2 that the gas flows out of tube 21 at the position of neck 5, so that no bubbling of the liquid takes place, as would indeed be the case if the gas were to flow out of the end of tube 21 situated in the bottle. Dispersal of sediment is also prevented.
  • Figure 2 shows that during pouring of liquid 3 from bottle 2, wherein the bottle is situated at the angle suitable for pouring relative to the vertical, closing element 32 displaces toward the second gas outflow opening 31 such that the second gas outflow opening 31 is closed and the end of tube 21 with non-return valve 30 situated in bottle 2 is conversely left open, whereby the gas flows through this end of tube 21 into bottle 2.
  • An advantage of such a spherical closing element 23 is that it is displaceable under the influence of gravitational force and is thus automatically adjustable depending on the position of bottle 2.
  • Reservoir 20 is connected releasably to device 1 by means of co-acting screw means 33 such that reservoir 20 can be removed for the purpose of refilling or replacing an empty reservoir.
  • Figures 4-6 show a device 101 according to a second embodiment of the invention. Corresponding components are numbered with corresponding reference numerals, increased in each case by 100.
  • Device 101 according to figures 4-7 differs in a number of aspects from the device according to figures 1-3, which aspects will be further elucidated hereinbelow. For the other aspects reference is made to the description relating to figures 1-3.
  • Figure 4 shows that the external design of device 101 differs from that of device 1 of figure 1.
  • Cap 104 thus takes a more compact form in the new design.
  • Pressing cylinder 115 has a number of grooves 140 extending along the length of the outer surface of cylinder 115, using which grooves 140 the rotation of cylinder 115 for the purpose of clamping the cap 104 onto neck 105 of bottle 102 can take place in simple manner.
  • Handle 108 forms the housing for reservoir 120 such that cap 104 has only one protrusion for both handle 108 and reservoir 120.
  • Handle 108 is provided here with screw means 133 such that a lower part of handle 108 can be unscrewed in order to remove a, for instance empty, reservoir 120, see figures 5 and 6.

  • Handle 108 comprises a displacing element 142 which is connected to valve 107 and which displaces and thereby opens valve 107 when handle 108 is displaced in the direction of neck 105 of bottle 102.
  • displacing element 142 fulfils the function of pressing element 10.
  • Displacing element 142 has a protrusion 143 which lies against a stop 145 connected to a spring 111 such that spring 111 presses displacing element 142 outward after the pressure on handle 108 has been released, and valve 107 closes. Valve 107 is therefore in its closed first position unless, preferably during pouring, a pressure is exerted on handle 108.
  • a locking element 144 is provided for the purpose of locking handle 108 in its non-pressed-in position. Figures 5 and 6 show that this locking element 144 is displaceable between a first
  • locking element 144 locks the non- pressed-in position of handle 108 and therefore prevents displacement of handle 108 (see figure 5), and a second position in which the displacement of handle 108 is released (see figure 6) . Placing locking element 144 in its first position prevents in simple manner unintended pressing of handle 108, and thereby unintended opening of valve 107.
  • the releasable spout 118 has a curvature for the purpose of pouring liquid 103 out of bottle 102 into for instance a glass 160 in simple manner and without dripping.
  • the curvature of spout 118 extends in the direction of handle 108, which indicates that handle 108 is situated on the underside of bottle 102 during pouring of liquid 103.
  • the handle 108 according to the invention can be pressed in easily and with only one hand of the user for the purpose of pouring liquid 103, as shown in figure 7.
  • gripping element 149 has a protrusion 153 disposed on the side of handle 108 facing toward bottle 102. In order to ensure that protrusion 153 is disposed on the side of handle 108 facing toward bottle 102, gripping element 149 is connected rotatably to handle 108 with a screw 150.
  • tube 121 has the above described curve, the curve being directed toward the side of bottle
  • Tube 121 differs from tube 21 of figures 1-3 in that the second gas outflow opening 131 is not closable but, using resistance and/or pressure, the gas automatically flows either out of opening 151 of tube 121 debouching in bottle 102 or out of second opening 131.
  • Tube 121 comprises for this purpose a relatively short inner tube 146 extending therein and debouching in tube 121. The gas is delivered here from reservoir 120 via inner tube 146 to tube 121 and then, depending on the angle of bottle 102 relative to the vertical, delivered via either second opening 131 or opening 151 to respectively neck 105 or relatively close to the bottom of bottle 102.
  • Device 101 further comprises a second valve 147 arranged hingedly in spout 118 by means of a hinge 152.
  • Second valve 147 is displaceable between a first position, in which second valve 147 closes spout 118, and a second position in which second valve 147 leaves spout 118 clear.
  • the closure of spout 118 by second valve 147 serves to prevent for instance vermin such as (fruit) flies or contaminants being able to get into device 101, or even bottle 102.
  • the closure of spout 118 can optionally be liquid-tight .
  • a pin-like actuator 148 lies on one side against second valve 147 and on the other against displacing element 142.
  • actuator 148 comes up against an obliquely rising surface of displacing element 142 and is thereby displaced in the direction of second valve 147, which second valve 147 it therefore displaces to the open second position thereof.
  • the hinge 152 with which second valve 147 is disposed hingedly in spout 118 is preferably adapted such that second valve 147 closes with a certain delay. It is hereby possible, when valve 107 is already closed and, due to the certain delay, second valve 147 is at least partially open, to pour liquid present in spout 118 out of spout 118.
  • spout 118 has a larger throughflow area than pouring opening 106. It will hereby be the case during pouring of the liquid that a determined quantity of air is continuously present in spout 118. This determined quantity of air in spout 118 ensures that liquid present in spout 118 can be poured therefrom, even after valve 107 has been closed.

  • figure 7 shows bottle 102 during pouring of the liquid.
  • the angle of bottle 102 relative to the vertical y is indicated in this figure 7 with a, this showing that the angle a lies between about 90° and 135° during pouring.
  • Devices 1,101 are preferably embodied such that they, or determined components thereof, are easy to clean.
  • Devices 1, 101 can on the other hand be embodied such that they, or components thereof, are intended for once-only use.
  • device 1,101, and cap 4,104 in particular, can be adapted to the size and shape of bottle 2,102.
  • Device 1,101 can optionally comprise a thermometer for measuring the temperature of liquid 3,103.
  • a dosing device can also be provided for dosing the volume of liquid 3,103 to be poured.
  • Handle 8,108 can for instance be displaced for this purpose in the direction of neck 5,105, wherein handle 8,108 moves back automatically after a predetermined period of time and thus automatically closes the opening after the predetermined period of time. This can be particularly advantageous for applications of device 1,101 in the catering sector when standard quantities of liquid,
  • the opening shown in the figures has a throughflow area of approximately 63 mm 2
  • the throughflow area may have any size, such as, but not limited thereto, a minimum of 5 mm 2 , a minimum of 10 mm 2 , a minimum of 20 mm 2 , a minimum of 30 mm 2 , a minimum of 40 mm 2 , or a minimum of 50 mm 2 .
