Abstract
A non-refillable gas lighter includes a member made of dry powdered metal and having a gas throughput according to the limited height of flame inserted in the flow route of the gas in the burner body upstream of the burner mouth which can be closed by a valve tappet. A helicoidal spring is disposed in an area of a push-buttom and a flint. One projecting end of the spring grips under the flint and presses the flint against a sparking wheel and another projecting end of the spring grips operatively in closing-direction on the push-button.
Claims2
A non-refillable gas lighter, comprising:
- a liquid gas reservoir including gas outlet means for releasing gas from said reservoir;
- a burner body defining a flow channel having a mouth which is in flow communication with said gas outlet means;
- a valve tappet disposed in said flow channel;
- a helicoidal spring having first and second ends;
- a spring-loaded push-button connected at one end with said valve tappet, and means mounting push button for displacing said valve tappet for selectively opening and closing the mouth of said flow channel with respect to said gas outlet means, said spring-loaded push-button engaging at another end the first end of said helicoidal spring and being lifted, by a spring force transmitted by the first end of said helicoidal spring, into a position corresponding to the closed position of said valve tappet, with said valve tappet being displaced into its closed position by the spring force of the first end of said helicoidal spring transmitted by way of said push-button;
- a spring-loaded flint having one end engaging the second end of said helicoidal sprig and an opposite end;
- and
- a sparking wheel mounted and means for mounting said wheel for rotation, by an external force, against the opposite end of said spring-loaded flint, the second end of said helicoidal spring being urged against the one end of said flint for pressing the opposite end of said flint against said sparking wheel.
