Definitions

  • This invention relates to a valve fitting for a keg particularly to safety features, tamper evidence and improved sealing between the keg and valve.
  • valve fitting for a keg of the kind generally used to store beer, or other liquids, under pressure.
  • the valve fitting may be of any kind but in particular, although not exclusively, may be of the kind referred to within the trade as a 'spear'.
  • the valve fitting to which this invention applies is one which is removable from the keg by the appropriate means such as a screw thread.
  • the valve fitting includes a tube which extends downwardly into the keg and this provides a passage for exiting of the fluid from the keg.
  • valve mechanism Spears are well known as the valve mechanism and extraction tube for dispensing pressurised liquids from containers.
  • spears There are a number of different types of spears and they have different configurations and shapes and this invention can be applied to any of the different types of spears.
  • the valve mechanism has two valves one has a larger diameter than the other and there is a tube which extends to within a few millimetres from the bottom of the container.
  • the larger diameter valve opens up into the top of the container whereas the smaller valve opens up and is connected to the tube.
  • the two valves reverse their rolls when filling the container to that of dispensing from the container. In the case of filling, the container is upside down with the spear at the bottom and the two valves are then opened.
  • the liquid to be stored in the container is forced in through the larger valve and this pushes any gas in the container via the tube and out through the smaller valve.
  • the container When dispensing the liquid in the container the container is the right way up with the spear at the top.
  • the two valves are open and gas under pressure comes in through the larger valve and forces the liquid via the tube out through the smaller valve.
  • the container At all stages in its life the container whether it is empty or full is under pressure. Therefore the pressure in the container can be dangerous to any unqualified person that attempts to remove a spear that does not have any safety features to prevent the spear from blowing out.
  • valve fitting for a keg including:
  • valve for permitting/preventing flow of fluid through a fluid conduit, the valve having a valve entrance
  • connection formation for engagement with a corresponding formation on a keg for securing the valve fitting to the keg
  • the at least one other aperture/passage is positioned closer to the valve entrance than the at least one filling aperture/passage.
  • valve fitting for a keg including:
  • valve for permitting/preventing flow of fluid through a fluid conduit, a connection formation for engagement with a corresponding formation on a keg for securing the valve fitting to the keg, and
  • At least one release aperture/passage which is at least partially formed in the connection formation of the valve body.
  • valve fitting for a keg including:
  • valve for permitting/preventing flow of fluid through a fluid conduit, a connection formation for engagement with a corresponding formation on a keg for securing the valve fitting to the keg,
  • At least one other release aperture/passage in the valve body which permits gas to pass therethrough whilst the connection formation on the valve body is at least partially engaged with the corresponding formation on the keg.
  • valve fitting for a keg including:
  • valve for permitting/preventing flow of fluid through a fluid conduit, a connection formation on the valve body for engagement with a corresponding formation on a keg for securing the valve fitting to the keg, and means for permitting gas to pass through or past at least a part of the valve fitting whilst the connection formation is at least partially engaged with the corresponding formation on the keg.
  • a keg including:
  • a formation for engagement with a connection formation of a valve fitting wherein the formation includes at least one release aperture/passage for permitting gas to exit from the keg whilst the formation on the keg is at least partially engaged with the connection formation on the valve body
  • valve fitting for a keg including:- a valve body; a valve for permitting/preventing flow of fluid through the fluid conduit, a connection formation for engagement with a corresponding formation on a keg for securing the fitting to the keg and a seal between the keg and valve body that has the thread within the pressure side of the keg.
  • valve fitting for a keg including:- a valve body, a valve for permitting/preventing flow of fluid through the fluid conduit, a connection formation for engagement with a corresponding formation on a keg for securing the fitting to the keg and two escape passages for the pressurised gas from the keg as the connection formation of the valve fitting is disengaged from the corresponding formation on the keg.
  • the first escape of pressurised gas starts in the initial stage of disengagement and the second occurs later through the disengagement
  • valve fitting for a keg including:- a valve body; and a valve for permitting/preventing flow of fluid through the fluid conduit, wherein an external surface of the valve body includes a thread that extends to a much longer length than the thread in the keg
  • valve fitting for a keg including:- a valve body; and a valve for permitting/preventing flow of fluid through the fluid conduit, wherein a rubber seal between the neck and spear body is sealed by a combination of both a radial and axial force
  • tamper evident member for positioning around a circumference of a formation of a keg neck and a formation around the valve body which when the valve is started to be disengaged the tamper evident member breaks
  • the present invention which can be applied to any of the spear configurations and shapes, it provides a blowout safety feature that prevents any unqualified/unauthorised persons from becoming injured should they attempt to remove the spear from a keg.
  • the invention includes tamper evidence that has to be destroyed or damaged before the spear can be removed to show that someone has tampered with the spear and attempted to remove it.

  • FIG. 1 shows a valve fitting 1 (a 'trilobe' spear) for a keg in accordance with the present invention.
  • the valve fitting 1 includes a valve, with a valve entrance 1 A, and a valve body 5.
  • the valve permits/prevents the flow of fluid through a fluid conduit.
  • the valve 1 includes a small valve 8 and a large valve 7, for assisting in filling a keg with a liquid, e.g. beer.
  • a seal 2 is in an open position showing the large valve 7 and the small valve 8 in the open position. These two valves 7 and 8 are opened when filling or dispensing by the appropriate mechanisms (note neither the keg filling nor the keg dispensing devices are shown in the figures).
  • a spring 4 pushes closed the seal 2 and closes the two valves 7 and 8 when the filling and dispensing mechanisms are removed from the spear 1 .
  • the valve body 5 contains all the parts of the spear with a tube assembly 6 being positively fixed to the valve body 5 and it holds all the spear 1 parts in place.
  • the valve body 5 is generally annular in shape and includes one or more filling apertures/passages in the form of ports 15.
  • the ports 15 extend through a sidewall 25 of the valve body 5.
  • the valve body 5 includes three ports 15.
  • the ports 15 are substantially equally spaced apart around a central axis A of the valve body 5 (i.e. at 120°).
  • the main purpose of the ports 15 is permitting beer into the keg when filling, although they do permit gas to escape from the keg on dispensing.
  • the valve body 5 includes a connection formation 50 on its outer surface.
  • the connection formation 50 is a male helical thread which has first and second thread parts 9, 10.
  • the first thread part 9 is continuous around the circumference of the valve body 5, with a thread length W and is located closest to the valve entrance 1 A.
  • the first thread part 9 is for holding and sealing the spear in place in a keg neck 18 (see figure 2a).
  • the second thread part 10 is a segmented thread that has a length Y and is located axially adjacent the first thread part 9.
  • Each segment has a thread width X (see figure 1 a(ii) and 1 b) and there can be any number and in this case the width is the same width as a column of material 1 1 , but this can change from spear type to spear type.
  • the first thread part 9 continues into the second thread part 10.
  • the keg 17 has a neck 18 which includes a corresponding formation in the form of a female thread 19 (see figure 2a).
  • the male thread 9, 10 of the valve body 5 is configured to engage with the female thread 19 of the keg 17, to secure the valve fitting 1 to the keg 17.
  • the valve fitting includes a sealing member 12.
  • the sealing member is a neck seal 12.
  • the neck seal 12 ensures that a fluid-tight seal is created by screwing the connection formation 50 of the valve body 5 into the female thread 19 of the neck 18 (see figure 2a and 4) which compresses the seal 12.
  • the neck 18 of the keg 17 includes a sealing surface 20 with which the sealing member 12 engages.
  • the sealing surface 20 is inclined at an angle to an elongate axis A of the valve fitting 1 .
  • a location ring 13 which is part of a tamper evidence feature 21 .
  • the valve fitting 5 includes one or more release apertures/passages 14A, 14B, 14C.
  • the release apertures/passages 14A, 14B, 14C permit gas to exit from the keg 17 while the male thread 9, 10 of the valve body 5 is at least partially engaged with the female thread 19 of the keg 17.
  • the release apertures/passages 14A are holes which extend through the sidewall 25 of the valve body 5.
  • the release apertures/passages 14A are substantially equally spaced apart around the central axis A of the valve body 5 (i.e. at 120°) and are positioned closer to the valve entrance 1 A than the ports 15.
  • the release apertures/passages 14A are circular in cross-section, but they could be any other shape.
  • Figures 1 a(ii) and 1 a(iii) show a more detailed view of how the ports 15 and release apertures/passages 14A are arranged in the valve body 5.
  • the release apertures/passages 14A are offset from the ports 15, such that the release apertures/passages are located axially in line with the columns of material 1 1 between the ports 15. It should be appreciated that there may be any number of ports 15 or release apertures/passages 14A, and the release apertures/passages 14A need not necessarily be positioned above the columns of material 1 1 , although this configuration is advantageous for strength of the fitting provided.
  • valve body 5 at the lower end of the second thread part 10 there is provided a non-threaded portion 10A (shown in figures 1 a(ii) and 1 a(iii)). Where the thread is at its smallest diameter is the trough of the thread. The trough of the second thread part 10 has a smaller diameter Z than the diameter N of the non-threaded portion 10A. This can be seen in more detail in figure 1 a(ii).
  • the valve body 5 permits gas to flow around the outside of the valve body 5, past the non-threaded portion 10A. Gas flows into the valve body 5 through the ports 15, and exits from the keg 17 through the release apertures/passages 14A.
  • FIG. 1 b shows a U type spear body 5'.
  • the U type spear body 5' is an alternative body type to the valve body 5 previously described and is substantially the same as valve body 5 .
  • the valve body 5' has connection formation 50' in the form of the male thread 9', 10' which engages with the female thread 19' of the keg neck 18' .
  • the release apertures/passages 14B are grooves. Each groove 14B is formed in the outer surface of the valve body 5'. The grooves 14B are cut into the first thread part 9' on the valve body 5' axially adjacent the ports 15' although they could be axially adjacent the columns of material 1 1 .
  • the grooves 14B are specific to the valve body 5' and any other bodies with similar features and perform the same function as the holes 14A in the valve body 5 (figures 1 a(i) to 1 a(iii)). The function of the grooves 14B will be described in relation to Figure 5a.
  • the grooves 14B, and there can be any number, are deeper than the route or trough diameter Z' of the thread 9' on the valve body 5'.
  • the grooves 14B are formed in the first thread part 9' of the valve body 5'.
  • the release aperture/passage 14B need not be formed from a portion of the connection formation 50' which is cut out the release aperture/passage 14B could be formed by an alteration of the connection formation 50', such as a deepened thread trough.
  • Figure 2a shows the keg neck 18, including the female thread 19 with a thread length E which is used in conjunction with the connection formation 50, 50' on the valve body 5, 5' for screwing the spear 1 into the neck 19 and forming a seal with the neck seal 12 against the angled sealing surface 20 in the keg neck 18.
  • the angled sealing surface 20 in conjunction with the point contact P on the neck seal 12 provides improved sealing.
  • the improved sealing occurs firstly because of the initial contact that is achieved by the point P and then as the spear 1 is screwed in further to the keg neck 18 the neck seal 12 is compressed even further until the two location ring faces 13 (see figure 1 a(i)) and 16 touch. When these rings touch it prevents over compression of the neck seal 12 and therefore less damage to the seal 12 by over compression.
  • the neck seal 12 is compressed in both a radial and axial manner as it is pushed into the angled sealing surface 20 on the keg neck 18 (see figure 4 which shows these features). The result is to give longer lasting and improved first time sealing for this part of the assembly.
  • the neck 18 with a thread 19 which has a length E and an inside diameter F together with the angled sealing surface 20 are features that will be described further when referring to figures 4, 5a and 5b.
  • FIG. 2b A further embodiment is shown in figure 2b.
  • the release aperture/passage 14C is an axial slot 14C located in the female thread 19" of the keg neck 18" rather than in/on the valve body 5, 5'. .
  • the valve fitting 1 " used with the keg 17" may be similar to those already known.
  • FIG 3 which shows the tamper evident collar 21 that has an internal diameter D which is a free fit over the two location rings 14 on the spear body 5 and 16 on the keg neck 18.
  • the collar 21 and its function will be explained in Figures 4 and 5a(i).
  • this shows the spear 1 screwed into the neck 18 which is the position for the spear 1 when it is in use.
  • the collar 21 is shown around the neck 18 location ring 16 and the spear 1 location ring 13.
  • the two clip ends of the collar 21 are able to slide over the two location rings 13 and 16 during assembly but once in place cannot be slide off.
  • the various embodiments of the invention all provide a gas flow path between inside the keg 17, 17', 17" and atmosphere, while the valve fitting 1 , 1 ', 1 " is still engaged with the keg neck 18, 18', 18".
  • a common feature to all of the described embodiments, is that the connection formation 50, 50', 50" of the valve fitting 1 ,1 ',1 " is axially longer that the corresponding formation 19, 19', 19" on the keg 17, 17', 17". This permits the valve fitting 1 , 1 ', 1 " to be partially unscrewed/unsecured, and to let gas escape, without the valve fitting 1 , 1 ', 1 " and the keg 17, 17', 17” being completely disconnected.
  • Figure 5a shows the spear 1 and keg neck 18 in the position at which the spear 1 has been unscrewed to the point where the holes 14A in the valve body 5 are clear of the female thread 19 of the neck 18. Gas is permitted to exit from the keg 17 by flowing out through the holes 14A, and hence the pressure within the keg 17 is released prior to the valve fitting 1 being fully removed.
  • Figure 5b shows the grooves 14B formed in the first thread part 9' of the valve body 5'.
  • the grooves 14B define a through path between an interior of the keg 17' and atmosphere. Gas is permitted to flow through the path, defined by the grooves 14B, while the valve fitting 1 ' is still engaged with the keg neck 18'.
  • Figure 5c shows the axial slots 14C formed in the female thread 19' of the keg neck 18". As a valve fitting 1 " is unscrewed from the keg 17", the axial slots 14C define a passage between the valve fitting 1 " and the keg neck 18". Gas is permitted to flow through the passage while the connection formation 50" is still engaged with the keg neck 18"'.
  • Any one of the three alternatives for the first safety feature renders the spear safe from blowing out and injuring someone.
  • a secondary gas escape path is provided as illustrated in figure 5a(ii), when the valve fitting 1 , 1 ", 1 " is unscrewed further from the keg neck 18, 18', 18".
  • the non-threaded portion 10A, 10A' has a smaller diameter N than the diameter Z, Z' of the second thread part 10.
  • the tamper evidence collar 21 will break at its weak point 23. Once the collar is broken it shows that someone has attempted to tamper and remove the spear 1 .
  • the first blow out safety device occurs when the spear 1 is partly unscrewed out of the neck 18 and the holes 14A alternative one are exposed or the alternative two that the grooves 14B are exposed or the alternative three that the slots 14C are exposed to atmosphere. The exposure of these escape routes 14A or 14B or 14C permits pressurised gas to escape from the keg.
  • the second blow out safety feature is when the spear 1 is unscrewed further out of the keg neck 18 and then any residual gas pressure in the keg will escape through the gap between the diameter Z on the spear 1 body 5 and the internal thread diameter F on the keg neck 18. This renders the spear 1 safe from blow out and the breaking of the collar 21 acts as a tamper evident device.
  • the spear 1 is assembled back into the keg neck 18 it is screwed in until the point P on the neck seal 12 starts to make contact with the keg neck 18 angled sealing face 20. This starts the sealing process which continues to improve as the neck seal 12 gets more compressed until the spear 1 is fully tightened into the keg neck 18 and location collars 13 and 16 touch. By the collars touching it prevents over tightening and damage to the neck seal 12.
  • a spear and keg neck with tamper evidence, two blow out safety features and improved sealing between the keg and the spear in claim 1 This is characterised in that there is a neck thread 19 within the neck 18 with sufficient length of thread E to hold the spear in place as well as creating a screw force that is able to compress a neck seal 12 to prevent any gases escaping from the keg.
  • the neck seal 12 is gradually compressed starting at the point P as it makes contact with the neck 18 angled sealing face 20. As the spear 1 is further tightened so the neck seal 12 is compressed further. From the initial contact of point P with the angle face 20 there is a seal between the spear 1 and the keg neck 18. Further tightening of the spear 1 into the keg neck 18 further improves the sealing between the two parts until the two location rings 13 and 16 touch. When the two location rings touch it prevents over tightening and possible damage to the seal.
  • the tamper evidence comprises of a collar 21 that is firstly pushed over the locating ring 16 on the keg neck 18.
  • the clips 22 on the collar 21 when pushed over the locating ring 16 will spring and retract out of the way and permit the collar 21 to slide over the locating ring 16. Once in this position the collar 21 cannot be pulled off the locating ring 16 as the clips 22 will not retract in this direction.
  • the spear 1 is tightened into the keg neck 18 the other set of clips 22 will retract out of the way as they pass over the spear 1 locating ring 13. Again the clips 22 cannot retract in the opposite direction.
  • This is characterised in that the screw thread on the spear 1 body 5 has one part of the thread 9 which is continuous around the circumference with a length W with three alternative methods to get gas to escape from the keg 17 when the spear is unscrewed.
  • the first alternative is to have some holes 14A in this thread 9 that pass from the outside to the inside of the body 5.
  • the second alternative is to have some grooves 14B in the thread 9 that are deeper than the thread 9.
  • the third alternative is to have some slots 14C in the keg neck 18A that are deeper than the thread 19.
  • This is characterised in that the screw thread on the spear 1 has one part with a segmented thread 10 with a thread length of Y.
  • the number of segments is equal to the number of ports 15 in the spear 1 .
  • the width of each segment X is equal to the width of the columns between the ports 15. However below the ports there is no thread and the diameter at this point is Z.
  • Within the keg neck 18 there is a thread whose internal diameter is F.
  • the gap between the diameters Z and F is important so that should the safety feature in claim 4 above not completely exhaust all the gas in the keg then any residual gas can escape through the gap between Z and F.
  • the spear 1 will still be held in the keg neck 18 by the segmented thread 10 as it is still engaged with the keg neck 18 thread 19 and that is when the second safety feature works. Finally the spear can then be completely removed
  • a spear 1 and keg neck 18 with tamper evident and two blow out safety devices characterised in that the above can be used on all types and configurations of spears in the drinks and chemical industry where the spear is held in with a screw thread.

Abstract

Lorsque la pointe est dévissée d'un tonnelet sous pression, le dispositif inviolable se casse puis le gaz présent dans le tonnelet s'échappe par l'une des trois voies d'évacuation alternatives. Les trois voies d'évacuation alternatives traversent des trous dans le corps de pointe, des rainures dans le corps ou des fentes dans le col du tonnelet. Lorsque l'on dévisse davantage la pointe, une voie d'évacuation secondaire supplémentaire est créée par le biais d'un espace entre le col du tonnelet et la partie inférieure du corps de pointe. L'étanchéité entre le tonnelet et la pointe est obtenue par compression d'un joint carré au niveau d'un coin jusqu'à ce qu'il ne soit plus compressé lorsque les surfaces de col et de corps finissent par se toucher.
