Child resistant gas lighter

Abstract

The child resistant gas lighter of the invention has an ignition sleeve having a slit defined therein and an integrated safety cap having a press surface, an opposite slide surface, a direction bar formed on the slide surface which is inserted in the slit and is able to make the safety cap slidable in the slit. In use, a user has to move the safety cap against a bias spring by his thumb until the safety cap is no longer blocked by a top surface of a flame cover and then press down the safety cap. The invention is hard for children to get understand how to ignition thus making it safer for children, and needs a smaller pressing force thus making the gas lighter more adult user friendly without sacrificing child resistance.

AI Technical Summary

Benefits of technology

[0010]The main object of the invention is to provide a child resistant gas lighter which is hard for children to get understand how to ignition thus making it safer for children.

[0011]Another object of the invention is to provide a child resistant gas lighter which needs a smaller pressing force, making the gas lighter more adult user friendly without sacrificing child resistance.

[0012]In order to accomplish the aforementioned objects, the present invention provides a child resistant gas lighter having a fuel-storage chamber for containing liquefied gaseous fuel; an upliftable gas release nozzle mounted on the fuel-storage chamber; a piezoelectric unit mounted on the fuel-storage chamber and having a piezoelectric button which when pressed downward, is able to startup the piezoelectric unit to generate sparks for ignition; a pair of pillars securely mounted on the fuel-storage chamber; an ignition trigger having a ignition sleeve slidably mounted on the pair of pillars which when pressed down, slidable with respect to the pair of pillars and when released, resumable to its undepressed position; a lever rotatably mounted on the fuel-storage chamber which when the ignition trigger is pressed down, is able to uplift the gas release nozzle to release the gaseous fuel and at the same time depress the piezoelectric button to startup the piezoelectric unit to generate sparks; a slit defined in the ignition sleeve; a flame cover having a top surface and being installed on the fuel-storage chamber and fixed to the pair of pillars; and, an integrated safety cap having a press surface, an opposite slide surface, a direction bar formed on the slide surface which is inserted in the slit and is able to make the safety cap slidable in the slit, a pair of stoppers formed on the direction bar which is able to prevent falling off of the safety cap with respect to the ignition sleeve when sliding, a pole formed on the direction bar, a bias spring installed on the pole biasing the safety cap with respect to the ignition sleeve, and, a shoulder near the first end of the safety cap.

Problems solved by technology

However, a child is unable to complete the two movements in one single action so that the safety lock can prevent the piezoelectric lighter from being ignited by the children.” (col.

The operation button (432), an area of which is smaller than that of the ignition cap (41), needing a larger pressing force from the thumb of a user, who may have a very skinny thumb, increases the difficulty of completing ignition from either children or adults.
