Definitions

  • the present invention relates to cartridges for pressurized liquefied gas such as the type used for camping stoves and lanterns and similar applications.
  • such cartridges consist of a generally cylindrical casing having a bottom wall, a side wall and an upper wall equipped with a perforable central part.
  • these cartridges must be internally equipped with a safety device having the function of preventing gas leakage following perforation of the upper wall by the equipment user.
  • the safety device of the perforable cartridges in question may consist of a valve with a spring-loaded obturator, for example as in the case of document FR-A-2901863 , or more simply of a seal facing the perforable part and carried by an elastic element tending to push the seal around this perforable part, as described for example in document EP-B-1406041 .
  • the seal is annular, so as to be passed through by the piercing member of the apparatus connected to the cartridge, and the elastic element has at least two bearing points so as to bear against at least one inner wall of the cartridge.
  • the direct bearing involves instability to the seal, as well as some complications in mounting of the safety device inside the cartridge.
  • document EP-B-1406041 proposes several solutions, all having a relatively complex construction owing to the fact that the elastic element bearing the annular seal and the related support are made in one piece together.
  • the present invention aims to overcome the aforesaid drawbacks, and to provide a perforable cartridge for liquefied gas in which the safety device is capable of ensuring the necessary reliability, along with a simple and economical construction, both from a manufacturing point of view and in relation to its assembling and and mounting inside the cartridge.
  • this object is achieved by means of a cartridge for liquefied gas of the type defined in the preamble of Claim 1, whose peculiar characteristic resides in that it comprises a support distinct from said elastic element and consisting of an elastic ring forcedly engaged above an inner annular projection of the side wall of the casing formed in the vicinity of its upper wall, and in that said elastic element is formed by an arcuate strip having two opposite arms mechanically engaged with two diametrically opposed areas of the elastic ring.
  • each of said two arms of the arcuate strip has respective hoooking appendages engaged above and below said elastic ring.
  • the invention also relates to a method for manufacturing the cartridge, with particular reference to the steps of assembly and mounting of the safety device.
  • the cartridge for liquefied gas comprises a casing having an essentially cylindrical-shaped canister 1, having a side wall 2 and an upper wall 3 formed of a single piece, and a bottom wall 4 fixed to the edge of the side wall 2 typically by means of roller seaming.
  • the upper wall 3 has, in a conventional manner, a lowered central portion 5, which is perforable by thrusting the supply duct of an apparatus such as a stove, a lantern, a heater or similar gas-powered appliances.
  • the side wall 2 includes, in the vicinity of the upper wall 3, an inner annular projection 6 that forms the peripheral support for a safety device, indicated as a whole by 7, and represented in greater detail in Figures 2 and 3 .
  • the annular projection 6 has an inclined slide surface at its bottom part 6, and a radially-orientated flat surface at the upper wall 3 part.
  • the safety device 7 is formed by three components: an elastic element 8, an annular seal 9 carried by the elastic element 8, and a support 10 of the elastic element 8.
  • the elastic element 8 consists of a metal strip, typically made of harmonic steel, to the central part of which the seal 9 is fixed, and whose arms extending radially from opposite parts of the seal 9 are each formed with respective sets of terminal hook appendages of mechanical coupling of which the side ones, indicated as 12, are bent below the central one, indicated as 11.
  • the length of the strip 8 is greater than the inner diameter of the elastic ring 10 so that, when the arms 8a, 8b are coupled to the elastic ring 10 in the manner outlined below, the strip 8 assumes the arcuate configuration shown in Figures 1 and 2 .
  • the seal 9 typically produced by means of molding a soft thermoplastic material, has a generally triangular cross-sectional profile, as represented in Figures 1 and 2 , and is formed of a single piece with a base 13 which, as is also represented in Figures 4 and 5 , has a pair of integral feet 14, forcibly engaged against corresponding holes 15 of the strip 8.
  • the elastic ring 10 which is a distinct and separate piece relative to the strip 8, has a flat configuration and an open gap 16. In its undeformed condition, its outer diameter is greater than the inner diameter of the annular projection 6 of the cartridge 1.
  • Figure 6 schematically shows the successive assembly steps of the safety device 7, and its mounting within the cartridge 1, after the formation of a single piece composed of the upper wall 3 and the side wall 2, plastically deformed in order to form the inner annular projection 6, and before applying the bottom wall 4.
  • the arms 8a, 8b of the strip are elastically deformed in order to mechanically connect by hooking the terminal appendages 11, 12 respectively below and above two diametrically opposed areas of the elastic ring 10, preferably offset by 90° with respect to the gap 16.
  • the safety device 7 is then introduced axially within the side wall 2 until the elastic ring 10, becoming radially deformed, goes beyond the inner annular projection 6, and is forcedly snap-fit engaged thereabove. This step is facilitated by the slide conformation of the lower part of the projection 6.
  • the annular seal 9 faces the perforable part 5 of the upper wall 3, and axially bears against its edge under the thrust exerted by the elastic strip 8.
  • the final step consists of attaching the bottom wall 4 to the edge of the side wall 2 of the cartridge 1.
  • the seal 9 has an annular design, as a matter of fact it is more preferable that it so designed to be not passed through by a piercing member associated with an apparatus employing the cartridge.
  • the seal 9 can be formed by a solid body shaped as a non-pierceable plug or, in case the seal be still annular, the strip 8 would be formed centrally with an embossment or projection protruding axially within the seal towards the perforable part 5, so as to be intercepted by the piercing member thus preventing the latter from passing through the seal.
