Definitions

• the present invention relates to a device for dispensing a liquid under pressure as well as an apparatus for issuing multiple portions of a liquid under pressure incorporating at least one device according to the invention.
• EP 0077910 in which an issuing nozzle is disclosed.
• the nozzle comprises an outer tubular member and an inner tubular member arranged coaxially one inside the other.
• the inner coaxial member is provided with a resilient sealing element at a distal end and the outer tubular member has been provided with a nozzle shaped open-end.
• the inner tube is activated for example by electromagnetic means pulling the inner tube up relative to the outer tube.
• the nozzle may therefore be activated anywhere by activating the electromagnetic means.
• Substantially similar devices or constructions are known from GB 2447920 or US 4533070.
• the nozzle arrangements in these three prior art disclosures are more or less equivalent and all rely on for example magnetically activated means in order to open or close the issuing nozzle.
• GB2369817 disclose a dispenser handle for use when dispensing liquids such as strong spirits from a bottle.
• the handle comprises a reservoir into which a predetermined volume of liquid is filled. The filling is regulated by a ball valve system internally in the handle/reservoir. By activating a lever (handgrip) a central stem arranged inside the reservoir is elevated.
• the distal end of the stem is provided with a valve body, which cooperates with a valve seat near the outlet in order to open or. close the outlet from the reservoir.
• the stem is hollow at the distal end in order to allow air to enter the res- ervoir, making it possible for the liquid in the reservoir to escape.
• the lever further have the function of manipulating the stem such that the ball valve is opened/closed in order to allow further volumes of spirit into the reservoir.
• This construction is specifically designed for spirits having no or very little sugar con- tent, in that it is impossible to clean the interior of the reservoir, without completely dismantling the device. Spirits having a high alcohol content will not pollute the mechanism. Furthermore other liquids as for example soft drinks and beer having a sugar content will relatively quickly clog up the interior of the device, due to the fact that especially sugar substances will adhere to the interior surfaces inside the reservoir - thereby render the device useless.
• US 5603363 is an apparatus known for dispensing liquids into containers such as cups and the like.
• the container must be equipped with a magnetic marker, such that as the container is placed around the issuing nozzle of the device, the magnetic marker will be recognized by a sensor on the apparatus, whereby the apparatus will open the issuing nozzle and issue the liquid into the container.
• the liquid will be issued as was the case with the devices mentioned above relatively close to the bottom of a container.
• WO 0152621 an apparatus for dispensing a carbonated beverage, such as for example a soft drink or beer, where the apparatus comprises a dispensing nozzle which nozzle at a distal end is provided with electric or electronic switch means which when encountering the bottom of a container activates a controller in the apparatus.
• the controller carries out a number of processes before the liquid is dispenses such as for example reducing the pressure in the liquid to be dispensed which is forwarded be- forehand to an intermediate reservoir.
• the apparatus furthermore includes an elevator for the container such that the container for example in the shape of a cup may be placed on the elevator and the apparatus activated in order to dispense liquid.
• the cup After activation the cup is elevated until the bottom of the cup comes into contact with the electronic switch means arranged in the distal end of the nozzle.
• the liquid in the intermediate reservoir is pressure reduced to a suitable pressure close to atmospheric pressure after which the liquid is dispensed into the cup.
• the elevator After the dispensing has terminated, the elevator lowers the now filled cup and makes it available for the user.
• the invention also aims at providing an apparatus by which it is possible to issue multiple beverages simultaneously.
• the invention addresses this by providing a device for dispensing a liquid under pres- sure where said device comprises connection means for connecting said device to the source of liquid, and where the device in the opposite end of the connection means has an outlet body which outlet body may be brought into a closed position where no liquid is dispensed, and an open position where liquid is dispensed, which outlet body incorporates a separate valve body cooperating with a valve seat, where said valve body has a head portion and a stem portion, where said stem portion in the closed position extends out of an opening in said outlet body, and where a lower surface of said head portion in the closed position is in contact with said valve seat and in said open position is out of contact with said valve seat.
• valve body as a completely separate member which is mechanically activated by for example bringing the bottom of a container into contact with the stem portion of the valve body
• a very simple and reliable mechanism is provided. Furthermore, from a cleaning perspective it is relatively easy to clean the outlet body containing the valve seat and the valve body, whereas for example looking to the prior art as discussed above with reference to WO 0152621 and GB2369817 a number of interior surfaces of the device, are very difficult to access. Furthermore, by having a valve seat engaging the lower portion of the head of the valve body it is ensured that the pressure originating from the pressurized liquid will force the valve body effectively into contact with the valve seat, when the valve body is not elevated, for example by contact with the bottom of a container.
• the prior art de- vice relies on a closure between an upper part of the valve body and a coaxially arranged tubular member or that the valve body is withdrawn into the tubular member and by means of an O-ring provides sufficient sealing action against an interior wall of a tubular member. Both these arrangements have to counter the pressure in the beverage to be dispensed whereas the present invention uses the pressure in the liquid in order to force the valve body against the valve seat and thereby attain a simple and reliable closing.
• a very fast opening of the dispensing valve is achieved. This is important in that the sooner a lami- nar flow (or substantial laminar) is achieved the less foam is generated. As the object is to provide liquid dispensation, the foam generation shall be avoided, apart from the desired foam generation, as will be further explained below.
• a further advantage compared to prior art devices is the arrangement of the valve body relative to the outlet body.
• the opening By extending the stem of the valve body through an opening in the outlet body, the opening also serves as guidance for the valve body's movements relative to the valve seat. In this manner it is achieved that the valve body will be correctly placed relative to the valve seat and thereby effectively close the valve.
• the device according to the invention is connectable directly to the source of liquid under pressure, for example a keg of beer, and as such is a very simple device.
• the underlying principle of the present invention therefore basically differs from the cited prior art in that activation of the device is achieved by inserting the outlet portion of the device into a container into which it is desirable to dispense a liquid. By engaging a surface of the container, typically the bottom, with the stem of the valve body the valve is opened.
• the device has a longitudinal axis where said outlet body is arranged coaxially around said axis, and an inner cavity is arranged inside said outlet body where said cavity has one or more outlet openings downstream from said valve seat and an opening coaxial with the axis for allowing the stem portion of the valve body to extend to the exterior of said outlet body where said cavity has a size allowing the valve body to move freely along the axis a predetermined distance.
• valve body By furthermore maintaining the valve body inside a cavity where the cavity is dimensioned to allow the valve body to move freely and at the same time allowing the liquid under pressure to flow past the valve body, it is possible to control the dispensation of the liquid by designing the cavity appropriately such that the valve body in combination with the cavity will provide a substantially laminar flow. Furthermore, the outlet open- ings below the valve seat foresee that the liquid is issued very close to the bottom radially from said longitudinal axis towards the sides of the container in which the liquid is to be dispensed. In this manner it is achieved that it is possible to dispense the liquid very quickly i.e. an average pint glass may be filled in 2 - 5 seconds.
• valve body due to the pressure in the liquid will be urged against the valve seat and thereby the closed position, where when the stem portion of the valve body is pressed towards the outlet body the valve head will be forced out of contact with the valve seat, thereby allowing liquid to issue from the outlet body.
• the pressure in the liquid will urge the lower surface of the valve head portion against the valve seat guided by the stem portion in the opening in the outlet body thereby efficiently creating a closed valve.
• mechanical influence on the stem portion will cause the lower surface of the valve body's head portion to be lifted from the valve seat whereby it is possible for the liquid to issue.
• the prior art WO 0152621 provides for an equalizing chamber as an intermediate storage for the beverage where the pressure inside the liquid is lowered prior to the dispensation. By lowering the pressure, part of the C02 in the liquid will disappear which to a user will result in a relatively "flat" drink. It is therefore desirable to dispense the drink at a pressure, where the C02 in the liquid is maintained dissolved in the liquid as long as possi- ble and in a manner such that excessive foam generation is avoided. With the present invention this is achieved by providing a substantially laminar flow through the device out through the outlet openings and past the valve body.
• the flow area through the de- vice and in particular through the outlet body is between 0,5 to 4 times more preferred 1 and 2 times the flow area of the inlet in the connection means.
• a resilient member is arranged coaxially with the longitudinal axis on the outside of the outlet body, at least partially surrounding the opening allowing the valve stem to extend from the outlet body.
• the resilient member serves to protect the container into which the liquid is to be dispensed in that the outlet body may advantageously be made from stainless steel and as such, when being brought into contact with for example a glass container, may cause damage. This is especially true due to the rapid rhythm of dispensation such that the exchange of containers takes place relatively fast whereby the risk of damage increases. Furthermore, the resilient member also serves to ensure that a certain distance is kept between the bottom of the container and the lowermost surface of the outlet body.
• the resilient member is compressible, where when the resilient member engages a surface, the valve head is lifted a predetermined distance from the valve seat, allowing the liquid to flow in a substantially laminar flow, whereas when the resilient member is compressed, the valve head will be in a position near the upper limit of the inner cavity, thereby creating a turbulent flow in the liquid flow.
• This embodiment is particularly interesting in that by designing the cavity correctly it is possible to dispense pressurized liquid such as for example beer, first as a laminar flow and after compressing the resilient member creating a turbulent flow whereby foam is generated. In this manner it becomes possible to design the beverage such that it has a suitable head of foam without substantially slowing down the process of dispensing the beverage.
• This is achieved by providing a cavity having an extent along the longitudinal axis of the device such that as the device is brought into contact with the bottom of a container, the valve body's stem engages the bottom of the container thereby elevating the lower surface of the valve body's head portion from the valve seat whereby liquid under pressure is dispensed as discussed above.
• the upper part of the valve head is at least partly convex, and that dimples, notches, grooves and/or ridges are provided on said upper part.
• This configuration of the upper part of the valve head is especially interesting in the embodiment described above where it is desirable to generate foam.
• the configuration of the upper part of the valve head may be used to enhance the foam generation. In this manner it becomes possible to increase the rate of dispensation and at the same time generate foam due to the unevenness of the upper part of the valve head.
• connection means comprises a bayonet coupling incorporating an activable one way valve, whereby the device may be separated or connected from the source of liquid.
• the device will be manufactured from stainless steel, and by being able to detach the device at the connection means it is possible to place the device for example in a dishwasher whereby a thorough cleaning of the device may be achieved or to replace it if for one reason or another a malfunction occurs.
• various size cavities and outlet openings may be especially suitable for various types of liquids and therefore it may be desirable to have various devices ready depending on the liquids to be dispensed.
• the device as such may be manufactured from plastic more or less for one time use only which is to be understood as for example if a device according to the invention is used at a theatre, concert hall or other one day event, it may be possible just to discharge the device after use or after an appropriate time interval and install fresh clean devices such that all hygienic issues may be addressed simply by discarding the devices after use and replacing with fresh, clean devices.
• the device is relatively simple in its construction and may be manufactured as injection moulded parts, the cost of the device may be maintained at a relatively low level making it feasible to discard the devices without a significant expense which would be the case if the device was manufactured from stainless steel or other more expensive material and process.
• a stem portion is provided between said outlet body and said connection means, where said stem portion has a liquid conduit.
• the stem portion serves to allow the outlet body to be placed in contact with the bottom of the container even for containers which are relatively high such that the connection means, for example as will be described below, may be incorporated in a handle which under normal use should be kept out of the container and the liquid which is to be dispensed.
• the length of the stem portion may be adapted to the container's size/height or may be of a sufficient standard length such that various sizes of containers may be used.
• the invention is also directed at an apparatus for issuing multiple portions of a liquid under pressure incorporating at least one device as described above wherein one or more devices are mounted in a vertically moveable holder along the longitudinal axis of the device, where the apparatus comprises means for moving the one or more devices into a position in a corresponding plurality of containers arranged in an array under- neath the devices, where the projecting valve stem engages the bottom of said containers, whereby the valve head is lifted free from the valve seat and the outlet body issues pressurised liquid in the container, and to a position where the outlet body of the device is above the rim of said containers.
• a flow meter or a timer is connected to the outflow of liquid from the source, such that only a predetermined amount of liquid is dispensed by the devices. In this manner it becomes possible to automatically dispense liquid simply by pressing a button whereby the containers are brought into engagement with the valve body and a predetermined amount of liquid is dispensed into the containers.
• the apparatus according to the invention is provided with a washing station where the outlet body is withdrawn into said washing station in the apparatus, where said station substantially surrounds the outlet body and, if provided also at least part of the stem, where said washing station either comprises a number of nozzles positioned to wash the outlet body's exterior and stem, the outlet openings, and the inner cavity, or where a source of UV light is arranged for treating all surfaces of the outlet body, the valve body and the stem if provided.
• the sugar will act as a glue whereby the valve body will become glued to the inside of a cavity in the outlet body.
• the washing station may also advantageously be provided with a source of ultra-light which is known to kill bacteria and other germs.
• a relief spring is arranged between the valve body and the outlet body, where said relief spring urges the valve body against the liquid pressure, i.e. away from the valve seat.
• the relief spring will be balanced such that only a minimum pressure will be needed in order to elevate the valve body from the valve seat.
• the relief springs force may be adjusted on site, such that the spring force may be adjusted according to the local circumstances.
• the pressure in the beer tank may also change over time during use, such that it may become necessary to adjust the relief springs force during use.
