Abstract
In a preferred embodiment of the invention, the lighter comprises an igniter having a striker wheel which may rotate about an axis first in a clockwise direction and second in a counter-clockwise direction when the wheel is viewed from its side. A stopping means is mounted on the wheel so that its range of movement at least in the clockwise direction is limited. It is while the wheel is being rotated in its clockwise direction that it and the igniter's flint may cooperate together to create a spark which ignites the lighter fuel. When the wheel is rotated in the counter-clockwise direction, no spark is created. When the wheel has been rotated to its extreme limit of its clockwise movement, the lighter can no longer be ignited unless the wheel is moved in accordance with two separate actions, that is, first rotating the wheel in the counter-clockwise direction and then back in the clockwise direction. Because two separate movements are required, the chances that the lighter will be accidentally made operational are reduced, as is the likelihood that a child will light the lighter.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
