Definitions

  • the invention relates to an insert to be fitted to a valve for a cartridge for storing liquefied gas under pressure, such as butane or propane - LPG.
  • a cartridge for storing liquefied gas under pressure such as butane or propane - LPG.
  • These cartridges may be connected to combustion devices / appliances and are used for preparing coffee, boiling various decoctions and roasting food.
  • Known cartridges are disposable rather than refillable; they have various dimensions and capacity ranging from 190 gr. to 500 gr.
  • One known type of cartridge is connected to the combustion devices by perforation.
  • Such a pierceable cartridge is presented in Figure 1 of European Standard Fpr 417:201 1 .
  • Other known cartridges for storing gas include a storage container for storing the gas and a valve, which connects the cartridge to the combustion device. In operation the cartridges provide through their valve evaporated gas to the combustion devices, which are safely connected therewith.
  • Such known cartridges are provided with a thread in order to screw the cartridges to combustion devices which are provided with complementary thread.
  • a cartridge with a threaded centre boss valve cup is presented in European Standard Fpr 417:201 1 .
  • the cartridge receives a combustion device through a clasping action.
  • US patent US 6,202,982 describes an appliance with a body 8 and a rotating part 9 that carries tabs 19 and is connected to a lever 23.
  • the lever 23 can be rotated by the user between a locked position, to lock the appliance to a cartridge 2, and an unlocked position, to release the appliance from the cartridge 2.
  • a relative rotation of the rotating part 9 with respect to the body 8 to the locked position forces the tabs 19 provided in the rotating member 9 outwards and engages the tabs 19 in a groove that is below an annular rim 6 of cartridge 2.
  • European patent application EP 251 1587 suggests fitting to the valve of the cartridge, a ring-shaped adaptor with lugs extending in the axial direction of the adaptor.
  • the lugs are to engage with the teeth of the appliance that is shown in the international application WO 2006/042971 .
  • With such an adaptor there is no need to provide the valve of the cartridge with teeth, which are complementary to the teeth of the appliance.
  • the invention aims to a cartridge that may be used with the known appliances having a body and a rotatable member. Further, the invention aims to a cartridge with high safety level with regard to liquefied gas leakage and to the robustness and strength of the valve. Further, the invention aims to a cartridge that provides an alternative manner of locking any cartridge with a rotatable member to gaz appliances. Further, the invention aims at an insert for a valve of such a cartridge.
  • An insert according to the invention is defined in independent claim 1 .
  • a valve for a gas cartridge comprises a jacket with an outer wall, a boss and a bottom wall that connects the outer wall and the boss.
  • the valve further comprises an insert fitted to the valve, whereby the insert and the valve have complementary means that prevent at least the relative rotation between the jacket and the insert.
  • the insert has an annular body that is made from a compressible material with hardness in the range from 12 Sh A to 80 Sh A.
  • Sh A denotes Shore hardness, type A.
  • Embodiments, which are only examples are made of material with hardness in the range of 12 Sh A to 36 Sh A, for example silicon and ethylene vinyl acetate or 50 Sh A to 70 Sh A, for example rubber.
  • the annular body may have an annular portion that is fitted in a groove or fold formed in the outer wall of the jacket.
  • the insert includes two annular cylindrical portions with a common axis and disposed one at the top of the other.
  • the insert has a face in contact with the valve of the jacket and a free face configured to abut to an appliance.
  • the free face of the insert may be coated with removable adhesive to facilitate the engagement and disengagement of the cartridge and the appliance more than once.
  • the insert comprises a ring-shaped body and a base element rigidly connected thereto, whereby the material of the base element is made of a material with a hardness that is higher than the material of the body of the insert.
  • an insert according to the invention improves the leakproofness of the connection between the appliance and the cartridge, because the pressure that is exerted to the insert and to the bottom of the jacket of the valve as a result of the force acting between the cartridge and the appliance, seals any escape route from the container to the environment.
  • One reason of defective connections that may cause leakages from the container is the tolerances between the appliance and the cartridge that may lead to an unstable connection between the two parts.
  • Such tolerences may exist also in the case of a cartridge with a threaded centre boss valve cup and an appliance with a complementary thread.
  • Figure 1 shows a cartridge and a combustion device / appliance.
  • Figure 2 shows a safety valve before connecting it to the storage container.
  • Figure 3 shows the safety valve after in the gas cartridge.
  • Figure 4 shows an insert before fitting the insert to the valve.
  • Figure 5 shows a section of the top of a cartridge with an insert according to the invention.
  • Figures 6 and 7 show schematically two alternative examples of an insert according to an invention fitted in a valve of a gas cartridge.
  • Figures 8 to 10 show schematically further alternative examples of an insert according to an invention fitted in a valve of a gas cartridge, which may be made of more than one component.
  • FIGS 11 and 12 show schematically further alternative examples of an insert according to an invention.
  • Figure 1 shows a cartridge 60 and an appliance 70.
  • the appliance 70 has a body and a rotating part such as the body and the rotating part of the appliances described in US 6,202,982 or WO2006/042971 and in the discussion of the state of the art of the present document. Further, the appliance 70 has locking elements, i.e. the tabs of the appliances described in US 6,202,982 or WO2006/042971 and in the discussion of the state of the art of the present document (page 1 , last paragraph and page 2, first paragraph), which are configured to interact with the cartridge 60 and to lock the appliance 70 with the cartridge 60.

  • the cartridge comprises a storage container 30 made of tinplate and a safety valve 10.
  • the safety valve 10 has a jacket 1 with an almost cylindrical boss 12 and an almost cylindrical outer wall 13.
  • the boss 12 defines in its interior an almost cylindrical space 14.
  • the safety valve 10 includes a cylinder 3, a piston 8 and a spring 2.
  • the cylinder 3, piston 8 and spring 2 are placed within the space 14 defined by the boss 12.
