Abstract
A pocket lighter of the present invention comprises a gas container having an outlet valve through which ignitable gas is released. An igniter device having a reciprocative plunger is also provided. The igniter device is operative to produce a spark when the plunger is axially moved. A thumb actuator is operative to cause opening of the outlet valve and axial movement of the reciprocative plunger, thereby producing a controlled flame. The pocket lighter is constructed and arranged such that at least ten pounds of force is required to operate the thumb actuator.
Claims15
A pocket lighter comprising:
- a gas container having an outlet valve through which ignitable gas is released;
- an igniter device having a reciprocative plunger which operates against a first predetermined force of an internal spring, said igniter device being operative to produce a spark when said plunger is axially moved;
- a thumb actuator operative to cause opening of said outlet valve and axial movement of said reciprocative plunger to thereby produce a controlled flame;
- at least one actuator spring contributing a second predetermined force of at least about five pounds to a total force required to operate said thumb actuator;
- and
- whereby said pocket lighter is constructed and arranged such that said total force required to operate said thumb actuator is child resistant, but only a force exceeding said first predetermined force is necessary to cause ignition of said igniter device.

A pocket lighter comprising:
- an outer housing having an open end;
- a housing end cap configured to be fit into said open end of said outer housing;
- a gas container located in said housing, said gas container having an outlet valve through which ignitable gas is released;
- an igniter device located in said housing, said igniter device having a reciprocative plunger operative against a first predetermined force of an internal spring to produce a spark when axially moved;
- a thumb actuator located at said housing endcap and movable with respect thereto, said thumb actuator operative to cause opening of said outlet valve and axial movement of said reciprocative plunger to thereby produce a controlled flame;
- at least one actuator spring contributing a second predetermined force of at least about five pounds to a total force required to operate said thumb actuator;
- a pivotal lever extending between said outlet valve and said thumb actuator;
- and
- whereby said pocket lighter is constructed and arranged such that said total force required to operate said thumb actuator is at least ten pounds, but only a force exceeding said first predetermined force is necessary to cause ignition of said igniter device.
