Description

[Detailed Description of the Invention] This invention relates to a disposable gas lighter, which has an extremely reduced number of parts, and has excellent strength and reliable operation.

An embodiment of this invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a fuel tank, which is made of hard transparent resin in the shape of a rectangular cylinder with an open top.

The lid body 2 fitted on the top surface has a vertical hole located in the front part, and a plug body 3 made of a soft elastic material such as rubber is fitted inside. A vertical hole 4 is provided, and a fuel injection pipe 5 is inserted from above, and a fuel suction string 6 is provided from below.
Each insert is included.

The lower end of the fuel injection pipe 5 is closed with solder or the like, and a small hole 7 is opened toward the front near the lower end. However, when the fuel injection pipe 5 is tilted forward, the vertical hole 4
Since a gap is created between the inner surface and the inner surface, a fuel passage is opened.

On the upper surface of the lid body 2, there is a vertical cylinder 11 located behind the fuel injection pipe 5, which has a file wheel 8 at its upper end and a flint 10 inside which is pushed up via a spring 9. It is permanently installed in an elevated position.

As is clear from FIG. 3, this vertical tube 11 has an inclined fitting 13 having an inclined surface 13' for pressing the collar fitting 12 of the fuel injection pipe 5 at the lower front side, a finger hook 14 projecting from the upper rear side, and On both left and right sides, vertically elongated guide recesses 16, 16 to be engaged with engagement protuberances of a windshield 15, which will be described later, are provided by press working.

A cylindrical windshield 15 is attached above the fuel tank 1 with its lower end fitted into the fuel tank.

As is clear from FIGS. 2 and 4, this windshield 15 has a rear half that is sized to surround the finger hook 14 from both sides of the vertical tube 11, and has engagement ridges that protrude inward on both sides. 17.17 is formed by extrusion.

This device has the above-mentioned structure, and when the file wheel 8 is pushed down and rotated with a fingertip, the fuel injection pipe 5 is tilted forward by the tilting metal fitting 13 of the vertical tube 11 that descends against the spring 9 at the same time as ignition. Since the fuel passage is opened and ignition combustion is performed, the structure is simple and can be manufactured at low cost. At the same time, the finger hook 14 fits into the windshield 15 and prevents the upright cylinder 11 from falling backward due to compression, so ignition operation is reliable, and the windshield 15 does not fit into the fuel tank 1. Continuous circumferential surface has snot 5 on the back
It is a cylindrical body that is made of thin metal at low cost, is extremely robust, and has no risk of failure.

Note that the engagement between the vertical tube 11 and the windshield 15 is achieved by providing an engagement protuberance 17 on the windshield 15 side in the illustrated embodiment. may be provided.

Claims (1)

[Scope of utility model registration request] A plug body 3 made of a soft elastic material such as rubber is fitted on the top surface of the fuel tank 1, which has a protruding cylindrical windshield 15 having a sleeve (S) on the back surface at the upper end. 3, the lower end is closed, and a fuel injection pipe 5 with a small hole 7 opened toward the front near the lower end of the bulge is installed vertically, a collar 12 is attached to the fuel injection pipe 5, and the upper end is filed with a file behind it. A car 8, a flint 10 pushed up inside by a spring 9, an inclined metal fitting 13 having an inclined surface 13' for tilting the fuel injection pipe 5 forward by pressing a collar 12 on the front side, and a finger hook 14 on the rear side. Both sides of the vertical tube 11 are engaged with the inner surface of the windshield 15 via the engagement ridges 17 and the guide recesses 16, and the finger hooks 14 are fitted into the windshield 15, so that they are always raised by the spring 9.
