Claims
- 1. A lighter comprising:a hollow casing having a first side wall disposed in spaced apart relation to a second side wall, a first end wall disposed in spaced apart relation to a second end wall, an open top, and a bottom wall connected to the side walls and end walls; a cover pivotally attached to the casing by a hinge disposed on the first end wall adjacent to the open top; and, an inside unit having at least one transverse rib disposed across a majority of the width of at least one of the side walls and integrally formed therein, the inside unit sized such that the transverse rib fits snugly inside the casing so that the inside unit is held in position by a frictional fit yet can be removed from the casing by hand, the transverse rib positioned such that it is near the bottom wall when the inside unit is inserted into the casing.
- 2. The lighter of claim 1, wherein the transverse rib is disposed substantially parallel to the bottom wall of the casing.
- 3. The lighter of claim 1, wherein a cross-section taken along a longitudinal axis of the transverse rib is defined by a curve having a single radius.
- 4. The lighter of claim 1, wherein a cross-section taken along longitudinal axis of the transverse rib is defined by a curve having multiple radii.
- 5. The lighter of claim 1, wherein the transverse rib extends from a first corner where the first side wall connects to the first end wall to a second corner where the first side wall connects to the second end wall.
- 6. The lighter of claim 5, wherein the transverse rib has a first cross-sectional area adjacent the corner and has a second cross-sectional area adjacent a midportion of the transverse rib, the second cross-sectional area being larger than the first cross-sectional area.
- 7. The lighter of claim 1, wherein the first side wall and the second side wall have a transverse rib disposed thereon.
- 8. A pyrophoric lighter, comprising:a hollow casing having a first side wall disposed in spaced apart relation to a second side wall, a first end wall disposed in spaced apart relation to a second end wall, an open top, and a bottom wall connected to the side walls and end walls; a cover having a pair of spaced apart side walls and a pair of spaced apart end walls, the cover pivotally attached to the casing by a hinge connected to the cover and to the first end wall of the case adjacent to the open top, the cover having a cross member disposed in spaced apart relation to the end wall of the cover; and, an inside unit having a hollow housing defined by a first side wall disposed in spaced apart relation from a second side wall, a first end wall disposed in spaced apart relation to a second end wall and a top plate, the first and second side walls extending above the top plate and being formed to provide a wind screen and a front and rear pair of lugs, the inside unit having a lever mounted between the rear pair of lugs and a spring-biased plunger for biasing the lever against the cross member when the cover is closed, the inside unit having a flint wheel mounted in the front pair of lugs, the flint wheel disposed adjacent to the flint and to a wick extending from a fuel reservoir defined inside the housing, the inside unit having at least one transverse rib disposed across a majority of the width of at least one of the side walls and integrally formed therein, the inside unit sized such that the transverse rib fits snugly inside the casing so that the inside unit is held in position by a frictional fit yet can be removed from the casing by hand, the transverse rib positioned such that it is near the bottom wall when the inside unit is inserted into the casing.
- 9. A method of manufacturing a lighter, comprising the steps of:providing a hollow casing having a first side wall disposed in spaced apart relation to a second side wall, a first end wall disposed in spaced apart relation to a second end wall, an open top, and a bottom wall connected to the side walls and end walls; providing a cover pivotally attached to the casing by a hinge disposed on the first end wall adjacent to the open top; providing an inside unit having a hollow housing defined by a first side wall disposed in spaced apart relation from a second side wall, a first end wall disposed in spaced apart relation to a second end wall and a top plate, the first and second side walls extending above the top plate and being formed to provide a wind screen and a front and rear pair of lugs, the inside unit having a lever mounted between the rear pair of lugs and a spring-biased plunger for biasing the lever against the cross member when the cover is closed, the inside unit having a flint wheel mounted in the front pair of lugs, the flint wheel disposed adjacent to the flint and to a wick extending from a fuel reservoir defined inside the housing; and, integrally forming at least one transverse rib disposed across a majority of the width of at least one of the side walls and integrally formed therein, the inside unit sized such that the transverse rib fits snugly inside the casing so that the inside unit is held in position by a frictional fit yet can be removed from the casing by hand, the transverse rib positioned such that it is near the bottom wall when the inside unit is inserted into the casing.
