Definitions

  • the present invention relates to a safety device and method for bottles, in gas apparatus.
  • Portable or camping gas burners and more generally gas apparatuses provided with bottle or cartridge for feeding a butane, propane or LPG type of gas, generally have the problem of the accidental detachment of the bottle from the gas drawing apparatus with the consequent danger of fire (if the flame is ignited) or gas leak (if the flame is off).
  • the prior art gas apparatuses described above normally have a laterally closed or open cylindrical body, provided with an upper opening through which is inserted the gas drawing apparatus and with a lower opening, larger than the previous one, through which is inserted the bottle, which is then coupled with the gas drawing apparatus, in the sense that the apparatus partially penetrates in the bottle perforating it in gas tight fashion.
  • the bottle can be maintained in its seat and in the correct operating position by means of a typical bayonet coupling (with obvious problems with the possible accidental uncoupling of the bottle) or by means of an elastic device.
  • the elastic device can be obtained by means of a wire-like metallic element, so shaped as to be able to be inserted elastically and manually in the body of the apparatus to lock the bottle inferiorly and/or extracted therefrom to allow the extraction of the bottle, or a closure element with bayonet coupling can be used.
  • An aim of the present invention is to eliminate the drawbacks described above and to allow to obtain a device and a method for locking/unlocking the bottle that allow the extraction of the bottle itself only when the ignition or gas drawing apparatus is completely removed from the equipment and hence the flame is absent.
  • the device comprises an element for retaining the bottle in the body of the apparatus and prevent its accidental egress, which device is inserted in the same opening through which the bottle is inserted and is so shaped as to allow the extraction or egress of the bottle only after a rising movement of the bottle within the body.
  • Said element is so shaped that the rising movement of the bottle or cartridge can take place only after extracting the drawing apparatus from the body or case.
  • Said element is preferably constituted by an annular retaining element that is elastically inserted into the body or case, encompassing the lower part or bottom of the bottle or cartridge and simultaneously constituting a lower end stop thereof.
  • the method for safely extracting a bottle or cartridge from a gas apparatus provides for the egress or extraction of the bottle or cartridge from the body or case to be possible only after a step of rising the bottle or cartridge inside the body or case.
  • the number 1 globally indicates a gas apparatus of the type comprising an ignition apparatus 2, a body or case 3 for housing a bottle or cartridge 4 of gas (preferably butane, propane or LPG), and a known gas regulation and drawing group 5 for regulating the flow of the gas that feeds the ignition apparatus, accordingly regulating the produced flame and for guaranteeing both the gas tight coupling with the cartridge and the drawing of the gas.
  • gas preferably butane, propane or LPG
  • the apparatus 5 is inserted in known fashion into the body or case 3, being screwed in a first upper threaded opening, not shown herein.
  • the bottle 4 is instead inserted inferiorly into the body through a second opening 6 having larger dimensions than the previous one.
  • the bottle is retained in its seat by an original annular element 7 which is elastically inserted in the same opening 6 through which is inserted the bottle 4, and is so shaped as to allow the extraction or egress of the bottle only after a rising movement of the bottle inside the body 3.
  • the drawing apparatus 5 When the bottle is inserted in the body and the annular retaining element 7 is also positioned correctly, the drawing apparatus 5 is superiorly screwed until a needle-like element punctures the bottle, penetrating therein, whilst an appropriate gasket creates a seal between the ignition apparatus and the bottle, thereby preventing gas from escaping.
  • the perforation of the bottle takes place as a result of the thrust exerted on the bottle by the drawing apparatus and of the fact that the bottle cannot move away inferiorly because it is retained in the case by the element 7 which bears down on a recess 8 that constitutes the lower edge of the body or case 3.
  • the element 7, which constitutes means for retaining the bottle 4 in the body 3, is preferably made of nylon 6 or in any case of a suitable material with elastic properties, and is inserted elastically in the body 3 encompassing the lower part or bottom of the bottle 4 and constituting a lower end stop thereof.
  • the element 7, which extends in annular fashion for about 320-350°, is originally provided with a step 9 along its own peripheral edge to house within it the bottom of the bottle.
  • the element 7 comprises two holes 10 (which in an embodiment variation not shown herein can be replaced by simple suitable shapes) for the insertion of two fingers to grip the annular element manually and extract it from the body 3.
  • the element 7 can be gripped and extracted only when the bottle does not bear down within the step 9, i.e. it is necessary to raise the bottle inside the body 3 by a few millimetres (preferably, 1 mm to 10 mm) to disengage it from the step 9. But the bottle is prevented from rising by the presence of the drawing apparatus inserted therein in gas tight fashion, and therefore it is necessary preliminarily to unscrew the drawing apparatus and completely extract it from the body 3 to allow an adequate movement of the bottle.
  • the height of the step (preferably from 1 mm to 10 mm) is calculated in such a way as to cause the extraction of the element 7 (and hence of the bottle) to be preferably able to take place only when the drawing apparatus 5 is completely extracted from the body or case 3.
  • the body or case 3 comprises a plurality of lateral openings 11 having the purpose of lightening the body 3, of allowing the vision of the cartridge (when present), and of improving the vaporisation and combustion of the gas.
  • the method of the present invention originally provides for the egress or extraction of the bottle 4 to be enabled only after the rise of the bottle in the body 3, preferably possible only as a result of a complete extraction of the ignition apparatus 2 from the body 3.
  • the device and the method of the present invention therefore provide a high degree of safety to the gas apparatus.
  • any opening by means of unscrewing the drawing apparatus 5) with a cartridge in which gas is still present, entails a leak but with the apparatus 5 still screwed to the body 3. In this way, the operator can intervene by re-screwing the apparatus and eliminate gas leaks at the origin.
