Abstract
The present invention provides a utility lighter with a safeguard that prevents inadvertent activation by children. Inside the lighter shell, the piezoelectric unit is located between the trigger and the safety button. When the trigger is pulled or pushed, the piezoelectric unit is moved. This movement can either be blocked by the safety button, or allowed to take place alongside the movement of the safety button. When the user holds the safety button and pulls the trigger simultaneously, the piezoelectric unit is blocked and generates a spark. If the trigger is pressed alone it stops before the piezoelectric unit is activated because of its movement backward. Children will find it very difficult to pull the trigger while retaining the safety button, vastly decreasing their chances of activating the lighter.
