Definitions

  • the invention relates to a safety device for use in an outlet opening of a pressurized beverage keg, in particular a beer keg, with a housing, a central tube, a bayonet plate which engages with outer projections in the L-slots of the housing part, further with a compression spring which is supported on the one hand on the bayonet plate and on the other hand on a sealing device.
  • Various types of safety devices of the aforementioned type are known in practice. They serve to seal a pressurized beverage keg, in particular a beer keg, after filling and during transport at the outlet opening and to be connected to a dispensing head when the beverage is subsequently filled.
  • the safety devices are inserted into the respective outlet opening of the beverage keg.
  • the part of the beverage keg simply referred to here as the outlet opening generally has a pipe socket which partially projects into the beverage keg and is provided with an internal thread at the outer upper end, so that the safety device can be screwed tight after use by means of an external thread.
  • the beverage keg is then subjected to further treatment processes, in particular pressure measurement for leaks, cleaning, etc., until the beverage keg is finally filled and closed at the inlet opening.
  • this embodiment has the disadvantage that the safety device with its individual parts must be used in the disassembled state because the dimension of the bayonet plate is larger than the diameter of the outlet opening or the said pipe socket because of the fixed hook.
  • the bayonet plate must therefore first be individually inclined through the outlet opening on the inside and pivoted into the correct position, after which the actual assembly of the safety device must take place with the bayonet catch, etc.
  • these manipulations are extraordinarily cumbersome and time-consuming in view of the large number of barrels that arise.
  • the invention is therefore based on the object of providing a safety device which, in the assembled state, can be brought into the operating position by simply pressing it into the outlet opening and then screwing it tight.
  • At least one movable locking element which is designed and arranged such that it is opposite the edge of the outlet opening during the operation can dodge and reaches behind the inner edge of the outlet opening in the operating position.
  • FIGS 1, 4 and 5 show an embodiment of a safety device for use in an outlet opening, not shown in the drawing, of a pressurized beverage keg, in particular a beer keg.
  • the device has a housing 1 with an external thread 2, which, as described, is provided for screwing in and final tightening in an internal thread in the outlet opening.
  • the housing part 5 is reduced in diameter, namely to adapt to the known, not shown pipe socket at the outlet opening of the beverage barrel. To seal this against a sealing ring 6.
  • openings 7 are also provided for the passage of compressed gas, in particular Co2, when a tap is installed.
  • the bayonet plate is provided with three outer projections 12, 13 and 14 distributed around the circumference.
  • the safety device also has a central tube 15, which extends in a known manner with its lower end close to the bottom of the beverage barrel.
  • the upper tube part 16 is somewhat tapered relative to the lower one, ie it is kept smaller in diameter, but it is made in one piece with the remaining part of the central tube.
  • An end plate 18 is fastened to the upper end of the central tube 15. Furthermore, the upper end of the tubular part 16 is surrounded by a sealing ring 19 and a support ring 20.
  • a compression spring 21 in the form of a helical spring, which is supported on the one hand, namely at the lower end on the bayonet plate 11 and on the other hand with the upper end on the support ring 20 and thus on the sealing ring 19 and the end plate 18 of this entire sealing device.
  • the safety device has a movable locking element 22, which is designed and arranged such that it can evade during the deployment process with respect to the not shown edge of the outlet opening or the pipe socket at the outlet opening and then in the operating position behind the inner one Edge of the outlet opening engages.
  • the locking element 22 is preferably held between a part of the bayonet plate 11 and the compression springs 21, and in the operating position it projects outward beyond the housing part 5. It is essential that the locking element is movable in any direction. For example, it could also be moved within the plane that runs perpendicular to the image plane of FIG. 1 by means of a guide or the like. In the preferred exemplary embodiment according to FIG.
  • the locking element 22 is pivotally mounted at the inner end, so that it can pivot upwards through an angular range 23 into the position shown in broken lines, ie in a position in which the locking element is located completely within the lower housing part 5 is located and does not prevent when the safety device is pressed into the outlet opening of the beverage barrel.
  • the pivoting movement is caused by the fact that the outer edge of the locking element lies against the relevant inner wall of the outlet opening, so that the locking element is automatically pivoted upwards.
  • Part of the locking element 22 projects through this window to the outside, the lower window edge 25 and / or the bayonet plate 11 acting as a stop for the locking position.
  • the locking element 22 in the embodiment according to FIG. 1 it is guided in the operating position in a recess 34 in the bayonet plate 11, the surface of the recess being flush with the bottom edge 25 of the window, that is to say the height corresponds.
  • a particularly simple embodiment of the locking element is shown in perspective in Figure 2, namely it consists of a rectangular web 26 with an angled part 27 which engages behind the inner edge or in a recess of the bayonet plate 11, so that the locking element also in the radial direction and is simultaneously held under the pressure of the compression spring 21.
  • the locking element can also have a different design.
  • it can consist of a rectangular web 28 with a T-shaped widening 29 at the inner end.
  • a spherical inner end of the locking element can also serve the same purpose.
  • the window 24 described is closed on all sides.
  • FIGS. 6 and 7 essentially corresponds to that according to FIGS. 4 and 5.
  • the same reference numerals have therefore been used for the same or equivalent parts.
  • the window 30 is partially open downwards, ie next to one end of the lower window edge 33, which runs in the tangential direction and again serves as a stop surface for the locking element 22, an axially downwardly extending open slot 32 is provided in the lower housing part 5.
  • the width of this slot 32 corresponds approximately to the width of the locking element 22, so that it can be guided down through the slot.
  • the lower window edge 33 which acts as a stop in the locking position, has a greater width than the tangential bayonet slots 10, so that the locking element is still held even after the bayonet lock has been opened and can only emerge through the axial slot part 32 of the window opening 31 when it is turned further.
  • the invention which has been explained in detail above, essentially depends on the fact that the entire safety device can be inserted in a completely assembled form through the outlet opening of the beverage barrel, the subsequent disassembly is also that is, the safety device can be removed from the opening of the beverage barrel in a simple manner.
