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 object of the invention is to provide such a valve closure the unauthorised removal of which, or its components, is rendered difficult by making the manner of removal unobvious and also reducing to a minimum the risk of ejection of the valve of the closure by the pressure gas.
  • a valved closure for a pressure vessel such as a keg or a cask, comprises an externally screw-theaded neck, for rigid attachment as a mounting ring to the rim of a tap-hole in the vessel, the neck having internal angularly-spaced radial lugs, a valve- containing tubular body inserted coaxially in the neck, the valve body having external angularly-spaced radial lugs engageable with and disengageable from the neck lugs by axial displacement and rotation of the valve body, an internally screw-threaded collar carried by the valve body and screwed onto the neck, check means preventing axial withdrawal of the valve body from the collar and a locking ring assembly interposed axially between opposed parts of the collar and neck to hold the collar in a position preventing axial displacement of the valve body for disengagement of the lugs:
  • a resilient seal is provided between the valve body and the neck and the seal must be compressed by axial movement of the body before the lugs can be brought into engagement by rotation of the body.
  • the lockring ring is a split ring which can be opened at its split and passed laterally into or from its locking position and it may also be frangible so that its removal involves breakage, thus providing evidence of tampering and preventing re-use.
  • valve closure comprises a valve body 10 housing valve components, generally indicated by the reference 20 in Fig. 4, of the kind which are assembled in the body 10 from its inner end, the body including internally a valve seat 21 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 top flange 10a of lobed shape to provide a hand-grip for turning, a rebate forming an inward axially-facing shoulder 10b, angularly-spaced circumferentially-extending lugs 11 at about mid-length of the body, these lugs having at their ends anti-rotation stops 11 a, and an inward shoulder 10c near the inner end of the main part of the body.
  • the body 10 is inserted coaxially into a neck 12 which has a flange 12a at its inner end to form a mounting ring which is welded to the rim of a tap-hole of a keg or cask (not shown).
  • a resilient 0-ring seal 13 lies between a shoulder 12b on the neck and the shoulder 10c on the body 10.
  • the neck 12 has an external screw-thread 14 and internally has angularly-spaced lugs 15 of a circumferential dimension to allow the lugs 11 to pass axially between them and to fit between the anti-rotation stops 11 a when the body is turned to inter-engage the lugs.
  • the valve closure also includes a collar 16 which has an internal screw-thread 16a to engage the thread 14 on the neck. Within its outer end the collar has a circumferential groove in which is engaged a split metal check ring 17 the internal diameter of which is less than the outer diameter of the lugs 11.
  • neck 12 will remain fixed to the cask or keg and only the remaining components will be removed at any time.
  • the body and collar 16 are first axially inter-engaged and loosely held together by inserting the check ring 17 into its groove whilst projecting into the axial gap between the shoulder 106 and the lugs 11.
  • valve body 10 is now pushed down to compress the seal 13 to carry the lugs 11 axially clear of lugs 15 and the body is then rotated to align the sets of lugs 11 and 15. On releasing the body, the lugs 11 rise into abutment with lugs 15 which lie between the anti-rotation stops 11 a as shown in Fig. 2.
  • the collar 16 is now unscrewed upwardly on the thread 14 until its upper end abuts the valve body flange 10a and the check ring 17 abuts the shoulder 10b (Fig. 3).
  • a split locking ring 19 of plastics or other frangible material is now passed laterally into the groove 12c to occupy the axial space between the lower end of the collar 16 and the bottom of the groove.
  • the components are so dimensioned that unless the lugs 15 are properly engaged between the stops 11 a the locking ring 19 cannot be inserted between the collar 16 and the bottom of groove 12c.
  • Removal of the valve body 10 is effected by a reverse operation. After ensuring that the pressure within the cask or kegs is fully relieved, the locking ring 19 is removed, the collar 16 is screwed down to contact the bottom of groove 12c, and the lugs 11, 15 are disengaged by depressing and then turning the valve body 10. The body 10 and collar 16 may now be removed.
  • valve body 10 cannot be rotated because the anti-rotation stops 11 a contact the fixed lugs 15. Also the collar 16 shrouds the neck 12 and cannot be screwed up or down so that the method of removal of the body and collar is not obvious, thus militating against tampering with the closure.
  • the shoulders 10c and 12b are bevelled to facilitate rolling displacement of the 0-ring seal 13 during assembly of the closure.
  • the locking ring 19 as shown in Figs 4 and 5 is weakened by a deep circumferential groove 1 9a in its underside so that when the ring is removed, such as by a hook engaged in an eye 19b at the split of the ring, the outer part of the ring will tear before the remainder of the ring leaves the grooves 12c. Thus the ring 19 is not re-usable and its torn state indicates tampering.

Claims (6)

1. Fermeture à clapet pour un récipient sous pression, tel qu'un tonneau ou un tonnelet, comportant un col à filetage extérieur (12) pour être fixé rigidement comme un anneau de montage sur le rebord d'un trou de cannelle dans le récipient, le col ayant des pattes radiales intrieures angulairement espacées (15), un corps tubulaire (10) contenant le clapet introduit coaxialement dans le col, le corps de clapet ayant des pattes radiales extérieures angulairement espacées (11) pouvant coopérer avec les pattes du col (15) et en être dégagées par un déplacement axial et une rotation du corps de clapet, un collier à filetage intérieur (16) porté par le corps de clapet et vissé sur le col, des moyens d'arrêt (17) empêchant d'enlever axialement le corps de clapet du collier, et une bague de verrouillage (19) interposée axialement de façon amovible entre des parties opposées du collier et du col pour tenir le collier dans une position empêchant de déplacer axialement le corps de clapet pour dégager les pattes.
2. Fermeture à clapet selon la revendication 1, caractérisée en ce qu'un joint élastique (13) est monté entre le corps de clapet (10) et le col (12) et que le joint joint doit être comprimé par un mouvement axial du corps de clapet avant de pouvoir amener les pattes (11, 15) en coopération par rotation du corps.
