ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a lighter that is improved in strength includes a thinner wall portion to change the direction of explosion, if occurs. The present invention also relates to lighter that can increase the density of tobacco in the cigarette.
2. Description of the Related Art
Conventional lighters contain highly volatile fuel and thus might explode when they are placed in a vehicle and exposed to the sun. This may cause damage to the vehicle and injury to people in or adjacent to the vehicle. A further drawback to conventional lighters is that they cannot be attached to a key ring or the like. Smokers often place a filter cigarette upside-down and tap the filter end of the filter cigarette on a desk surface to make the tobacco become denser, yet the filtering effect is not improved, as the density in the filter portion is not changed.
SUMMARY OF THE INVENTION
It is the primary object of the present invention to provide a lighter that is improved in strength or has a thinner wall portion to change location of explosion, if occurs, thereby reducing possibility of injury to people.
It is another object of the present invention to provide a lighter that includes a through-hole in the lighter housing, thereby allowing the lighter to be attached to a key ring for convenient carriage.
It is a further object of the present invention to provide a lighter that includes at least one through-hole in the lighter housing through which a cigarette is passable for making the tobacco and the filter portion of the cigarette become denser.
A lighter in accordance with the present invention includes a lighter housing having at least one through-hole with a maximum diameter greater than a diameter of a cigarette and a minimum diameter smaller than the diameter of the cigarette. Thus, the cigarette may be passed through the through-hole to make the tobacco and the filter portion denser. The lighter housing may include reinforcing ribs to improve the strength. In addition, the lighter housing may include thinner wall portions to divert the force of explosion, if it occurs such that fragments and gas shall not scatter outward, thereby reducing possibility of injury to people.
Other objects, specific advantages, and novel features of the invention will become more apparent from the following detailed description and preferable embodiments when taken in conjunction with the accompanying drawings.
