<p>A roll and press gas lighter is rendered child resistant by an impeding element (26) mounted on the lighter body such that its surface (26') is preferably substantially flush with a low friction surface (16') which forms the outer periphery of the thumbwheels (16). The impeding element preferably comprises a protective strip which extends around the sparkwheel (15). In use the engaging surface (26') of the impeding element is engaged by the user's thumb simultaneously with the low friction surface, increasing the force required to rotate the sparkwheel and hence the child resistance of the lighter. The degree of child resistance of the lighter is determined inter alia by the smoothness of the thumbwheels and the position of the impeding element.</p> |
