FIELD OF THE INVENTION

The present invention is related to a disposable fuel can for a pocket lighter or table lighter.

BACKGROUND

Pocket lighters are small hand-held lighters which are easily stored in a garment pocket of a lighter user and easily held in a palm of a users' hand. Traditional pocket lighters contain built-in fuel tanks. Built-in fuel tanks of traditional pocket lighters hold a minimal amount of butane fuel storage requiring frequent refill or disposal/replacement of the pocket lighter. Moreover, many lighter users are reluctant to refill a lighter due to a complicated refilling process. Additionally, because of a variety of different butane suppliers, butane purity, butane pressures (mixed gases) and butane quality suffer causing a negative impact on a lighters' performance. Built-in fuel tanks contain extra mechanical parts used for refilling the tanks and are common causes of lighter repair or failure.
