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.

1 . A child resistant gas lighter having a fuel-storage chamber for containing liquefied gaseous fuel, an upliftable gas release nozzle mounted on said fuel-storage chamber, a piezoelectric unit mounted on said fuel-storage chamber and having a piezoelectric button which when pressed downward, is able to startup said piezoelectric unit to generate sparks for ignition, a pair of pillars securely mounted on said fuel-storage chamber, an ignition trigger having an ignition sleeve slidably mounted on said pair of pillars which when pressed down, slidable with respect to said pair of pillars and when released, resumable to its undepressed position, a lever rotatably mounted on said fuel-storage chamber which when said ignition trigger is pressed down, is able to uplift said gas release nozzle to release said gaseous fuel and at the same time depress said piezoelectric button to startup said piezoelectric unit to generate sparks, and, a flame cover having a top surface and being installed on said fuel-storage chamber and fixed to said pair of pillars, wherein the improvements comprising:
 a slit defined in said ignition sleeve;   an integrated safety cap having a press surface, an opposite slide surface, a direction bar formed on said slide surface which is inserted in said slit and is able to make said safety cap slidable in said slit, a pair of stoppers formed on said direction bar which is able to prevent falling off of said safety cap with respect to said ignition sleeve when sliding, a pole formed on said direction bar, a bias spring installed on said pole biasing said safety cap with respect to said ignition sleeve, and, a shoulder near said first end of said safety cap.   
     
     
         2 . The child resistant gas lighter as claimed in  claim 1 , wherein said child resistant gas lighter has a housing for containing said fuel-storage chamber. 
     
     
         3 . The child resistant gas lighter as claimed in  claim 1 , wherein said the press surface of said safety cap has a raised wale for antislipping when moved by thumb. 
     
     
         4 . The child resistant gas lighter as claimed in  claim 2 , wherein said press surface of said safety cap has a raised wale for antislipping when moved by thumb. 
     
     
         5 . The child resistant gas lighter as claimed in  claim 1 , wherein said flame cover further has a recess for receiving said shoulder of said safety cap, making said top surface of said flame cover be at a same level as a top surface of said safety cap. 
     
     
         6 . The child resistant gas lighter as claimed in  claim 5 , wherein said child resistant gas lighter has a housing for containing said fuel-storage chamber. 
     
     
         7 . The child resistant gas lighter as claimed in  claim 5 , wherein said the press surface of said safety cap has a raised wale for antislipping when moved by thumb. 
     
     
         8 . The child resistant gas lighter as claimed in  claim 6 , wherein said press surface of said safety cap has a raised wale for antislipping when moved by thumb.
