Definitions

  • This invention relates to valved closures for pressure vessels, such as kegs or casks for beverages dispensed through the valved closure by pressure gas admitted to the keg or cask through the closure.
  • the vessel has welded to it a tubular neck-like socket into which the valved closure is inserted, the socket and closure having mating screw threads or a bayonet type connection.
  • Such arrangements are generally satisfactory in practice, but have a disadvantage in that it is possible inadvertently to unscrew the closure of disengaged the bayonet connection whilst the vessel is pressurised internally. This dangerous possibility may occur for example when attempting to disengage from the closure a dispense head by which connection is made between the container and a dispense tap.
  • the closure is merely retained by a split ring which engages a groove internally of an annular cask fitting and overlies shoulders on the closure body.
  • the split ring is usually readily accesible and can be removed easily using a tool, e.g. a screwdriver. It this is done when the vessel is pressurised internally, the closure will be ejected with great force.
  • a security closure-fitting unit is also described in EP ⁇ A ⁇ 0102701 (Art. 54(3)EPC) wherein the body and valve means is retained by a top plate of which the marginal edge portions have been deformed to form a clench around the flared top 3 of the housing.
  • the plate further forms an integral constructional part of the valve means.
  • a valve closure for dispensing liquid from a pressure vessel has a neck, for rigid attachment as a mounting ring to the mouth of a tap body in the vessel, a valve-containing tubular body inserted co-axially in the neck and a rigid anti-tamper ring of malleable metal has an inner periphery shaped to engage the tubular body and a relatively thin outer peripheral skirt, which is to be deformed by a power tool, for conversion into a security collar with an inturned border in fitted engagement about the rim of a given neck, the security collar being separate from any valve component of the tubular body, whereby distortion or removal of the security collar from the neck by a special tool cannot affect the valve contained within the tubular body and only the anti-tamper ring has to be replaced each time the valve closure is removed from the pressure vessel.
  • the tubular body and the keg neck have mating external and internal threads
  • the tubular body also has a radially outwardly extending flange proximate the top thereof and the inner periphery of the security collar is shaped to axially engage the flange.
  • the security collar provides the sole means for axially retaining the tubular body in the keg neck.
  • the security collar of the above two embodiments in each case consists of a rigid collar of malleable metal having a thinner skirt to be crimped about a keg neck by a suitable power tool and similarly cut off by the use of a special tool.
  • Such collars are conveniently made of aluminium.
  • the security collar comprises two or more part rings, each having an inner periphery shaped to engage with a locking feature on or in the outer surface of the valve tubular body and an outer peripheral skirt to be deformed into said fitting engagement about the rim of a given neck.
  • the part rings are made of a deformable stainless steel.
  • the valved closure shown by Fig. 1 consists of a tubular valve body 10, housing valve components generally indicated by reference 12 and of the kind which are assembled in the body 10 from its inner end, the body including internally a valve seat 14 against which the valve seals and which prevents ejection of the valve.
  • the valve itself does not form part of the present invention and need not be further described.
  • the body 10 has a small, radially outwardly extending flange 16 near the top thereof and around the periphery of which a number of flats are provided to enable the body 10 to be rotated.
  • a keg or cask 18 has a tap hole 20 and a generally cylindrical neck 22 is welded to the keg about the tap hole leaving the hole mouth as a radially inwardly extending flange 24; an O-ring seal 26 being trapped between flange 24 and a complementary shoulder 28 on the valve body 10.
  • valve body 10 and the neck 22 have mating respectively external and internal threads; the valve body (and associated valve components 12) being screwed into the keg neck, using the aforementioned flats.
  • a rigid ring 30 is shaped internally to fit over the valve body 10 and its flange 16 and has an external, downwardly directed, relatively thin skirt 32 that is shaped to overhang an external lip 34 on the keg neck 22.
  • the collar 30, although rigid, is made of a malleable metal such as aluminium so that a suitably designed power tool can crimp the relatively thin skirt 32 around and underneath the neck lip 34 as shown in the Figure.
  • the ring 30, with its skirt 32 thus forms a strong collar that secures the valve body in the keg neck against axial withdrawal and against rotation.
  • valve can only be extracted from the keg if the securing collar 30 is removed and this requires the use of a special tool to cut the crimped collar off the keg neck. This securing mechanism will not only guard against accidental removal of the valve or casual interference but will guard against deliberate attempts at valve removal other than with a suitable tool.
  • the ring collar 30 is the only component that will have to be replaced each time the valve is removed and the keg refilled.
  • Fig. 2 shows another embodiment of the invention, in this case both open and closed, and like parts having been given the same references.
  • the valve body 10 has no external thread and the keg neck 22, although shown plain, could be a standard keg neck with an internal thread or bayonet socket.
  • the ring collar 30 has an inner axially depending flange 36 to trap the valve body 10.
  • the inside of the ring collar is also shaped to receive a dispense head.
  • valve body 10 together with an appropriate ring collar 30, enables conventional, non- secured valve components to be fitted and secured in any existing keg neck.
  • FIG. 3 shows a third embodiment of the invention and like parts have again been given the same references.
  • valve body 10 has a radially outwardly extending flange 15 at the top thereof and from the periphery of which depends a short axial skirt 17.
  • the keg or cask 18 is of stainless steel as is the neck 22; in other respects all is as described above.
  • Two separate U-section stainless steel half collars 29 and 31 retain the closure valve body 10 in the container 18; the inner skirts 33 of the collars being located in a pre-machined groove 35 in the outer surface of the valve body 10 prior to the insertion of the closure valve in the neck. Thereafter the half collars are self-locating within and around the neck and ready for the crimp operation which, with the aid of specially designed hydraulic equipment, crimps the outer skirts 37 of the collars around and underneath the neck lip 34 as shown in the Figure.
  • the half collars 29 and 31, with their skirts 33 thus form a strong collar that secures the valve body in the keg neck against axial withdrawal.
  • valve can only be extracted from the keg if the half collars 29 and 31 are removed and this requires the use of a special tool to cut the crimped collars off the keg neck. This securing mechanism will not only guard against accidental removal of the valve or casual interference but will guard against deliberate attempts at valve removal other than with a suitable tool. Spacing washer 39, shown to be located between the half collars 29 and 31 and the valved body flange 15, is for assembly purposes only.
  • the ring collars 29 and 31 are the only components that will have to be replaced each time the valve is decrimped and removed and refitted to the keg.
  • Another advantage of this embodiment especially when used with large flanged valves, is that the crimp is well "hidden” by the depending skirt, thus reducing the likelihood of abuse.
  • valve body design is such that a single ring can pass over the valve body and still secure the valve body and keg neck together, whereas it is the diameter of the valve body flange 15 in the third embodiment that necessitates the use of split ring collars.
  • valve body flange 15 in the third embodiment that necessitates the use of split ring collars.
  • either aluminium split ring collars or a stainless steel single ring collar could be used.
