  The present invention relates to a device for the production of the booklets at the NATIONAL PRINTING, 27. rue de la Convention - 75732 PARIS CEDEX 15 "Device for protecting a drum valve"

  protecting a drum valve, in particular a valve

  beer barrel or the like, a valve carried by a nozzle protruding from the bottom of the barrel to be

  connected to the filling or sampling pipe

  tively. Some drinks, or more generally liquids, such as beer, are packaged in returnable metal drums. Although there are drums of different capacities, their size and capacity

are in the process of standardization.

  Such a stainless steel beer can is represented

  in the cutaway view of Figure 1.

  This barrel i consists of a side wall 2 provided with reinforcing ribs 3, 4, two bottoms, 6 one of which (6) is equipped with a nozzle 7 provided with the valve 8. This valve, not shown in detail, is

  accessible through the front face of the end piece 7 and is

  lined by a dip tube 9 which is used for sampling

or filling the liquid.

  The tip 7 protrudes from the bottom 6 on some

  does not height which is nevertheless lower than the height

the edge 10 of the barrel.

  Drums are often handled

  very violent, whether full or empty.

  In the case of a keg of beer, the filling

  ge is through the valve. At the end of filling

  with beer, carbon dioxide is introduced

  mounted in the barrel under the bottom 6 (when the barrel is arranged in the position of use shown in FIG.

  Figure 1) to act as propellant gas.

  for the removal of beer.

  When drilling, the valve is re-

  related to the piping and the faucet of the counter.

  The valve comprises precision mechanics and

  seals. This valve is the essential element

  tiel and the most fragile of the keg of beer. Figure 2

  shows, in section, the shape of the valve whose

cription will not be detailed.

  The proper functioning of its valve is a determining factor in the distribution of beer

called "on pressure".

  Because of the essential importance of the valve which must not leak and allow liquid or gas to escape during storage or transport,

  the valve is checked very carefully at

  the return of the casks to the brewery.

  To protect the valve, it is known to

  a plastic or aluminum capsule

  minium. The plastic capsule is an extruded part.

  To carry brand markings for the product, large batches must be manufactured so that the unit price does not become prohibitive. It is therefore not conceivable to provide these capsules with very precise indications as to the date on which the beer is to be drunk.

particular type of beer, etc.

  Finally, the capsule is only suitable for one

valve size.

  At the moment of dropping the drum, he

  you have to tear the plastic cap with a knife.

  This can damage the rubber lips

of the valve.

  Aluminum capes, which protect known valve tips, are aluminum parts cut from a band that is embossed at the packing date. The piece of aluminum foil is cutting for the hands that handle it as

  for the valve that the cape is supposed to protect.

  To pierce the drum, it is necessary to tear

  remove the aluminum cap with forceps. It is necessary

  avoid, at all costs, that pieces of metal

  try on the valve as they will damage the valve. In general, this removal, either of the plastic cap or of the aluminum cape, is

  an unpleasant operation to perform and dangerous.

  In addition, current protection systems has the disadvantage that the indications on the plastic capsule are incomplete and not very visible; when the plastic cap or aluminum cap has been removed, it is no longer possible to know the brand of beer contained in the drum, the

  date of the last filling and the place of packing

  is lying. The present invention aims to remedy

  these disadvantages and proposes to create a

  protecting a barrel valve, especially a beer barrel, which effectively protects the valve against any damage, which can be adapted.

  valves and valve caps of different sizes

  tes, and allows to have indications relating to the contents of the drum, even after it has been pierced.

  For this purpose, the invention relates to a device

  protective device of the above type, characterized in that it comprises:

  A - a recovery plate intended to be

  on the valve of the tubular nozzle to protect

  handle the valve against shocks, B - a shrink sleeve to cap the wafer, the tip and the valve, the sleeve being heat-shrunk on the tip and the plate for

  hang the plate on the tip.

  This device is set up very simply and automatically or manually, and simply place the plate on the valve and then press the shrink sleeve over the tip of the valve and over the wafer. The sleeve is then retracted, for example by means of a stream of hot air. The sleeve traps the

  plate and clings to the tip.

  The wafer has a shape corresponding to

  that of the valve or the tip, that is to say, in general

  neral, a circular form. However, if others

  forms of mouthpiece should exist, it is easy to

  to fit a plate of different shape.

  As the wafer does not have to overflow relative to the front face of the nozzle provided with the valve,

  it is possible to use the same plate to diffe-

different types of drum.

  The indications relating to the product contained in the drum may be printed or marked on the sleeve. This impression can be done flat, before

  the realization of the sleeve. Thus, it is particularly

  interesting to print strips of monoriented heat shrinkable material, flat, to have a better quality of printing, then to fold

  this band to form a tube. The tube is itself

  me, reeled and debited at length

  in the automatic setting machine or

  manually if this is done.

  According to another characteristic, the man-

  heat-shrinkable sleeve has, before retraction, a greater length than that of the nozzle carrying the valve. To facilitate the insertion of the sleeve

  and not having to maintain or dispose of it

  particular, it is interesting that, as

  above, the sleeve is longer than the tip so that it overflows it to cover well

  the tip and the wafer after heat shrink.

  According to another characteristic, for a valve mounted on a circular tip, the wafer is a washer of diameter slightly less than

  outer diameter of the valve and / or the tip.

  According to another characteristic, the man-

  heat-shrink sleeve is a sleeve of syn-

  mono-oriented and in particular PVC.

  According to another characteristic, the man-

  chon is provided with inscriptions relating to the nature and

  the quality of the product packaged in the drum.

  According to another characteristic, the man-

  chon has a tear strip to facilitate its

  removal and removal of the wafer for use

the barrel.

  This tear strip is pre-cut or more generally made in the strip before or after printing, so that the sleeve, even before

  heat shrink, includes this tear strip.

  This facilitates the intervention of the user who drills the drum; this one does not have to use tools

  particular and especially knife.

  In a particularly interesting way, the

  sleeve has a separate transverse pre-cut

  on the one hand, the part provided with inscriptions

  to remain the mouthpiece and to allow the identifica-

  of the barrel, even after removal of the wafer and, secondly, the upper part of the sleeve intended to grip the front part of the tip and the protective plate of the valve, the tear strip

  only this pre-cut line.

  Thanks to the "lower" part of the sleeve which remains attached to the tip, the user has, at any time, the indications relating to the product contained in the barrel. It can know its exact nature, its date of putting in the drum, etc ... For the manufacturer, this simplifies the packaging because it does not have to stick a label on the bottom of the drum, label which, when the drums are stored outside, may be damaged by rain or must be removed at the time of return drums since the drum does not necessarily always receive the same type of

product or beer.

  The present invention will be described in a manner

  re more detailed with the aid of the attached drawings, in which:

  FIG. 1 is a perspective view of

  removed from an example of a beer keg to which the invention applies, FIG. 2 is a detailed view of the

  upper part of the shaft of Figure 1, cut to the

  Valve calf, - Figure 3 shows the valve of a barrel on which was placed the protective device before heat shrink,

  FIG. 4 shows the valve and the device

  after the heat shrink, FIG. 5 shows a sleeve belonging to the protective device, which sleeve is folded back to

dish.

  According to Figure 3, the protective device

  tion consists of a cover plate 11 placed on the valve 8 carried by the tubular nozzle 7 integral with the bottom 6 of the barrel. The device also comprises a heat-shrinkable sleeve 12 covering the wafer 11, the tip 7 and the valve 8 to hold the wafer 11 applied against the front face of the

the tip 7 over the valve 8.

  Figure 3 shows the protective device

  tion (11, 12) after it has been put in place.

  When the sleeve 12 is set up as

  put in place as described above, it is not

  heat-shrunk core. It is large enough to fit easily on the tip 7 and the plate

11.

  This sleeve 12 is preferably in one piece

  mono-oriented synthetic material and in particular

  PVC polyvinyl chloride. The plate 11 is in general

  a circular shaped plate with a diameter

  be slightly weaker than the upper edge of the tip and the valve 7, 8. It may also have

  other forms if, in particular cases, the

  end had to have a polygonal shape or other.

  Figure 5 shows a perspective view

  of a sleeve 12 after completion.

  Indeed, it is preferable, to achieve

  the sleeve 12, to start from a strip of thermal material

  morractable, to print this tape with the information 13 relating to the nature of the product,

  its date of manufacture or packaging, etc ...

  It is also interesting to provide the band with

  pre-cut transverse rods 14 as well as a tear strip 15. The tear strip 15 preferably joins the upper edge 16 of the future sleeve

  12 to transverse precut 14.

  Once these different operations have

  on the strip, the strip is folded so that the edges 17, 18 overlap and are glued to

  form a sleeve. The sleeve is then, preferably

  this, wound on a reel and is debited at the time of its use. We then get the sleeve & flat 12

appearing in Figure 5.

  On this sleeve, there will be a lower part

  19 and an upper part 20. After retraction

  tion and as shown in Figure 4, to

  The drum can be bored and can remove the plate 11 disengaging the valve 8, tearing the tear strip to the pre-cut 14. This allows to simply remove the "upper" part 20 of the sleeve then

  that the lower part 19 remains hooked on the

  end. It is thus possible, after drilling, to have

  always see the indications 13 on the barrel end.

  Advantageously, the lower part 19 may comprise a tear strip 21 extending from the lower edge 22 of the sleeve and reaching the

  transverse precut 14. This band 21 is

  aligned with the tear strip 15. Thus, the tear strip 21 makes it easy to remove the portion

  lower 19 without the need for tools. As the ban-

  15, 21 are not located in the extension of one another, there is no risk that at the time of removal of the tear strip, it is also detached the lower part 19 of the sleeve.

  Although the description given above con-

  mainly surrounds a barrel of beer, the invention may

  apply under the same conditions to all

  logue, with a valve like that of a keg of beer.
