Cl.
  • This invention relates to a throw away gas-lighter and more particularly, a throw away gas lighter which comprises a transparent or substantially transparent body and a transparent or substantially transparent fuel reservoir received in the body for rotational movement relative to the body and having gas flow adjusting means.
  • gas-lighters There have been proposed a great variety of gaslighters, but most of the prior art gas-lighters comprise a metal body and a metal fuel reservoir received in the body and therefore, the fuel within the reservoir could not be seen from the exterior of the lighter.
  • plastic gas-lighters have been proposed, in any of the prior art plastic gas lighters the body or casing concurrently serves as the fuel reservoir. Therefore, the prior art plastic gas-lighters are advantageous over the metal gas-lighters in that the fuel within the reservoir can be seen from the exterior of the lighters, but
  • the plastic flame-opening-defining component is easily scorched or melted away by the flame to give an unpleasant appearance to the lighter.
  • the friction wheel in any of the prior art gas-lighters is formed with a square through hole and mounted on a support part of the body of the lighter by means of a pin or shaft extending the square hole.
  • Such a prior art friction wheel has the disadvantages that the wheel 'requires the processing work for drilling the square hole, the pin or shaft has to be separately prepared and the assembly of the friction wheel requires the work for passing the pin or shaft through the hole.
  • one object of the present invention is to provide a throw away gas-lighter which can effectively eliminate the disadvantages inherent in the prior art gas-lighters referred to hereinabove and at the same time has advantages over the prior art gas-lighters.
  • Another object of the present invention is to provide a throw away gas-lighter which comprises a body or casing formed of transparent or substantially transparent material and a gas fuel reservoir formed of transparent or substantially transparent material and received within the body for manual rotational movement relative to the body and in which a clearance is defined by the body and reservoir for receiving an indication material such as an advertisement material so that advertisement effect can be simply obtained without the necessity for any external printing.
  • Another object of the present invention is to provide a throw away gas-lighter which comprises a body or casing and agas fuel reservoir received within the body for manual rotation relative to the body and provided with gas flow adjusting means at the outer end which extends beyond an adjacent part of the-body for access so that the adjustment of gas'flow from the reservoir can be effected by turning the reservoir by means of the adjusting means.
  • Another object of the present invention is to provide a gas-lighter in which the plastic at the area adjacent the flame opening formed in the plastic cap of the lighter is protected against scorch or melting so that the gas-lighter will have an extended service life.
  • a further object of the present invention is to provide a throw away gas-lighter which includes, a friction wheel assembly comprising a main friction wheel and a pair of separate opposite synthetic resin operation wheels which sandwich the main friction wheel therebetween and the wheel components of the friction wheel assembly can be separately produced and then assembled in a quite simple manner so that the friction wheel assembly can be produced on a mass production basis at a relatively less expense.
  • FIG. 1 is a side elevational view of the throw away gas-lighter constructed in accordance with the present invention
  • FIG. 2 is a side elevational view of said gas-lighter of FIG. 1 in partially longitudinal section;

  • the burner support body 18 has at the upper end a radially and outwardly extending integral annular flange 22 which has an outer face 23 where the burner support body is secured to the upper portion of the reservoir 2 at 4a by supersonic welding for rotational movement therewith.
  • the inner surface of the upper portion of the burner support body or the intergral flange 22 thereof is threaded for receiving the burner assembly in the manner as will be described hereinbelow.
  • the gas reservoir 2 is filled withthe liquefied gas 17 in any suitable conventional manner to a desired or predetermined amount, the burner support body 18 having the burner assembly 21 mounted therein in thread engagement with the threaded inner surface of the support body 18 is fitted in the open upper portion of the reservoir 2 and the burner support body 18 and reservoir 2 are supersonically welded together in the manner as mentioned hereinabove. Thereafter, the sub-assembly is fitted in the inermediate member 9 which has been previously supersonically welded to the upper portion of the body 1.
  • the intermediate member 9 is formed thicker at one peripheral edge (the right-hand edge 26 as seen in FIG. 3) than the diametrically opposite peripheral edge and the thicker peripheral edge 26 is formed a flint opening 28 therein.
  • a coiled spring 29' is received in the flint opening 28 and a flint 27 is also received in the opening 28 over the spring 29 to be normally urged outwardly thereby.
  • a friction wheel assembly 29 is rotatably mounted on the intermediate member 9 by means of bosses 31 and 31 in friction engagement with the flint 27.
  • a pair of integral ears 30 and 30 project upwardly from the thick peripheral edge 26 of the intermediate member 9 and the abovementioned bosses 31 are supported in the ears 30.
  • the wheel assembly 29 is more clearly shown in FIG. 7 of the accompanying drawings.
  • the wheel assembly comprises a main wheel body 36 having the opposite ends faces 33 and 33 which are formed therein with a center recess 34, respectively and the periphery of the main wheel body provides the abrasive surface which frictionally engages the flint 27.
  • sparks are struck between the main wheel assembly and flint to ignite the fuel spourting from the nozzle 42 of the burner assembly 21.
  • the friction wheel assembly 29 further includes a pair of opposite synthetic resin operation wheels 38 and 38 which have on the inner surfaces cylindrical knuried center bosses 37 to be received in the recesses 34 in the main wheel body 36 and on the outer surfaces the abovementioned bosses 31.
  • Each of the operation wheels 38 has a larger diameter than the main wheel body 36 and the inner surface of the operation wheel is formed with an annular projection 38 extending along the peripheral edge the inner diameter of which is substantially the same as the outer diameter of the main wheel body 36 to define a circular recess so that the opposite ends 36a of the main wheel body are fitted in the recesses in the operation wheels.
  • the friction wheel assembly 29 which has been fabricated by fitting the main wheel body 36 in the opposite operation wheels 38 is then mounted on the ears 30 on the intermediate member 9 thereby to complete the assembly of the friction wheel assembly 29 to the intermediate member and in consequence, to the body 1.
  • An actuation lever 39 is pivotally mounted on the intermediate member 9 right below the friction wheel assembly 29 and the lever has an outer manipulation end 40 and a bifurcated inner end 41 which engages the nozzle 42 under a bulged portion 46 formed adjacent the upper end 45 of the nozzle.
