Abstract:

A piezoelectric lighter with a child resistant ignition mechanism which prevents accidental ignition and ignition by unintended users and by minor children under the age of 5 years. The safety ignition mechanism is an activation device that requires two displacements in order to ignite the lighter. The displacements are achieved by applying a continuous and increasing force to the activating component in order to ignite the lighter. The first displacement unlocks the ignition device and the second displacement initiates simultaneously an electrical discharge and a fuel discharge, which results in a flame. Whenever a user discontinues the application of force to the activating component, the ignition mechanism returns to an inoperable, locked position. The effectiveness of this activating device in resisting the manipulations of children under the age of 5 years has been established by tests performed pursuant to the requirements of the United States Consumer Product Safety Commission.
