BACKGROUND OF THE INVENTION
Refillable lighters are utilized for lighting cigarettes, cigars, for starting campfires and the like. Common refillable lighters utilize butane or liquid lighter fluid, for example naphtha, for the fuel. A disadvantage with butane is that is performance degrades in extreme cold conditions. Most lighters that utilize liquid lighter fluid are not fluid tight and can leak the liquid lighter fluid and/or the lighter fluid evaporates in a relatively short period of time. Any improvements in the performance of lighters would be well received by the lighter-using public.
SUMMARY OF THE INVENTION
A fueled lighter for cigarettes, cigars, and the like having a main fuel containment housing body and a forward lighting end, with a forward hinged lid having closed position and an open position, the open position providing access to a flame generator assembly. The flame generator assembly providing a wind shield with a flame outlet that is perpendicular to the major dimension and elongate axis of the lighter. When the flame generator is actuated, this orients the flame upwardly with the housing body extending generally horizontally or slightly tilted from the horizontal. The flame generator assembly comprising a flame generator base with a fuel port positioned into the wind shield and an ignition means adjacent to the fuel port. The flame generator base is unitary or integrated with a post extending from the flame generator base, rearwardly. The post having a threaded end exposed at a rearward end of the housing. A threaded connector, which may be configured as a knob, attaches to the threaded end of the post and is tightened securing the fuel containment housing together that defines fuel reservoir. In an embodiment, the post and threaded connector hold a rearward end cap in a sealing arrangement with the housing. In an embodiment, the post and threaded connector hold the flame generator base in a sealing engagement with the housing.
In embodiments, the lighter has a forward sleeve with a closeable lid, the sleeve extending around the four sides of the housing and slidable on the fuel containment housing. The forward sleeve with the closeable lid having a first closed position on the containment housing where the lid is closed on the sleeve, and the sleeve with lid is forwardly positioned with respect to the fuel containment housing, and where the sleeve and closed lid enclose the flame generator assembly, including the wind shield and wick. In embodiments, the wind shield is entirely positioned rearwardly of the lid and is totally within the confines of the sliding forward sleeve in the closed position. The lighter further having an actuation portion that activates a transition from the closed position to an operational position. In the operational position, the lid is released from the sleeve and a bias to the lid causes the lid to rotate about 270 degrees to lay along a lower margin of the sleeve. Additionally, in the transition, the fuel containment housing moves forwardly within the sleeve such that at the operational position the windshield with wick projects forwardly out of the sleeve.
In embodiments, the flame generator base having a periphery that sealingly engages with the housing and also sealingly engages with the lid hinged to the housing hen the lid is in the closed position. The sealing engagements may be provided by a pair of O-rings. The fuel port may include a wick extending from an eyelet in the flame generator base, the wick extending into the fuel reservoir defined by the fuel containment housing body.
In embodiments, the post having a bore for receiving flints, the bore extending to a flint wheel rotatably positioned below the wind shield when the lighter is in the operational position. A spring may bias the flints into engagement with the flint wheel. In embodiments, a central axis of the bore with the flints is positioned forward of the axis of the rotatable flint wheel. An upper portion of the flint wheel is positioned in a lower slot defined in the windshield.
A feature and advantage of embodiments where the lid or cover is substantially flat and does not cover the windshield when in a closed position. This reduces the cumbersome extra volume of a cup shaped lighter lid when in an operational position.
A feature and advantage of embodiments is that the body configured as a fuel housing is sealingly attached to the flame generator base of the lighter with one or more O-rings sealing the connection. Moreover, when the lid is closed, an O-ring seals the lid also to the flame generator base. All component junctures providing a leakage or evaporation pathway are sealed with O-rings, providing a lighter that will retain its fuel much longer than a conventional liquid fuel lighter.
A feature and advantage of embodiments is that the wind shield opens generally at a 90 degree angle from the greater dimension of the body. This allows the lighter to be held horizontally with the wind shield open in an upwardly direction.
A feature and advantage of embodiments is that the wind shield has a plurality of outwardly projecting tapered nozzle portions. Such outwardly projection nozzles are believed to be more effective than simple holes in providing wind protection while allowing sufficient air for combustion. As air enters the narrow opening and the opening expands on the inside of nozzle, the air velocity is reduced more so that with simple aperture in a wall.
A feature and advantage of embodiments is a hinged lid that is retained in a sealed closed position by a pivoting latch. Additionally, a U-shaped pivoting latch provides a secondary securement of the hinged lid. The U-shaped pivoting latch pivots at a lower having a latched position where it extends forwardly toward the lid, and an unlatched position where
A lower integral or unitary latch bracket extends downwardly from the housing. A first latch has a pivoting latch lever with a latching end that hooks onto a feature on the hinged lid and an opposite manual actuation portion that can be depressed to disengage the latching end from the hinged lid. The lever may be spring loaded to urge it into the latch position.
A feature and advantage is a flame generator base that has an O-ring groove for sealing connection to the housing and an adjacent exposed O-ring groove for sealing connection to the hinged lid.
A feature and advantage of embodiments is a lighter with the opening of the windshield and the opening of a hinged lid are perpendicular or substantially perpendicular to one another. This provides enhanced wind protection and further provides a barrier to contacting the flame. r
A feature and advantage of embodiments is that a manually rotatable knob, rotatable without tools, projects from a rearward end of a lighter housing body providing an ergonometric configuration for easy gripping in the lighting-operational orientation. In embodiments, the knob threadedly attached to the flint tube holds the lighter together pulling a flame generating base unitary with the flint tube towards and into the housing body and an O-ring seals the opening.
A feature and advantage of embodiments is that a manually rotatable knob, rotatable without tools, projects from a rearward end of a lighter housing secures main components of the lighter together and closes the flint tube.
In embodiments, the knob engages against a rearward housing cap that is sealing engaged with an open lower end of the housing by sandwiching a seal between the cap and the lower housing margin.
In embodiments, the knob covers a flint reservoir that has a bore with internal threads on the post defining the bore, and threaded cap with external threads is secured in the bore. A coil spring in the bore and engaging the threaded cap urges the flints toward a flint wheel mounted on the flame generator base.
A feature and advantage of embodiments is that the metallic fuel containment housing is contained within non-metallic outer housing components to provide an enhanced gripping and holding surfaces. The outer housing may be a polymer, for example, with a significant lower heat conductivity than the metal of a main body of the fuel containment housing. In embodiments, a non metallic end cap extends over a rearward open end of the main body of the fuel containment housing, and a forward non metallic sleeve extends over the forward end of the fuel containment housing and enclose the metallic forward end of the fuel containment housing and the metallic windshield within the forward outer housing component, the sleeve, when the lighter is in a closed or non use state. Both outer housing components extending radially outward from the inner fuel containment housing such that during handling of the lighter, the metallic inner fuel containment housing is not contacted or is minimally contacted by the user. Particularly in cold ambient conditions, this is more user friendly.
A feature and advantage of embodiments is that the height of the lighter in the use position is significantly less than conventional lighters. First, the lighter has a use position where greatest dimension of the lighter is positioned horizontally. The height then is the second greatest dimension of the lighter. Secondly, the hinged lid is configured as a flap rather than being a cup, and the lid lays along the body barely increasing the height of the lighter. This minimal height of the lighter is more conducive to use in camping for example, to extend the lit lighter into openings in campfire wood piles.

DETAILED DESCRIPTION
Referring to FIGS. 1-6, a lighter 20 is illustrated in a closed position and an open use or operational position and generally comprises a fuel containment housing 22 having a housing body 24 and a lid 26 hingedly connected by way of hinge 28, a latching assembly 30, and a rearwardly extending knob 32. A flame generation assembly 40 is exposed when the lid 26 is opened and comprises a flame generation base 42, windshield 44 extending from the base, a fuel port 46, an ignition means 48 on the base. The lighter has a greatest dimension D1, a length, which extends generally horizontally when the lighter is in a closed position with an axis α1 horizontal. The lighter has a second greatest dimension D2, which is a height when in the use position, and a third greatest dimension D3, a thickness or width. Length dimension D1 illustrates the length when and the width dimension will each have a
In embodiments, the windshield 44 has four walls, two upright lateral opposing walls 52, 53 extending from the flame generation base, a lower wall 54 also extending from the base 42 connecting the two lateral opposing walls, and an distal upright wall 55 connecting the two lateral opposing walls. The windshield defines an open flame region 58 and a windshield flame outlet 59 which has an axis α2. The lateral side walls have outwardly projecting dimples 60 with apertures 61. The dimples are configured as outwardly projecting nozzle portions 64 formed in the sidewalls. These are believed to provide enhanced wind protection to prevent the extinguishment of a flame, but also providing adequate air for the combustion. As depicted in FIG. 6, high velocity air flow 67 when it enters the opening is slowed to a slower air flow 68 when it expands due to the increasing area of the diverging nozzle 69 of funnel.
The lid defines an opening 66 with an axis α3 that is perpendicular or substantially perpendicular to the axis of the windshield 44. The lid is attached to the housing body 24 by hinge 28 having hinge portions 72, 73 projecting upwardly from the housing body and are connected with hinge pin 75. A spring 76 can urge the lid to the open position.
Referring to FIGS. 1-7, the latching assembly 30 comprises a latching base 80 disposed on the housing body, a first latch 82 and a second latch 84. The first latch may be configured as a lever 86, with a fulcrum configured as a pin 88, and an actuation portion 89, and a hook portion 90 opposite the actuation portion with respect to the pin 88. The hook portion engages structure, such as a lip 91, best shown in FIG. 10, outwardly allowing the lid to be opened. A spring 92, shown in FIG. 7, may urge the lever to the latched position. Depression of the actuation portion 89 pivots the hook portion 90 outwardly allowing the lid to be opened from the closed position.
The second latch 84 comprises a U-shaped latch member 96 that has ends 98 extending into openings 101 on ribs 103, 104 of the latching base 80. A polymer tube or covering 106 may provide an engagement portion for the latch member. The latch member swings from a double latched position shown in FIGS. 1 and 2, to the seated unlatched position of FIGS. 3 and 4. The legs 107, 108 of the member may provide feet for seating on a flat surface. In embodiments, the second latch needs to be unlatched before the first latch can be released, providing assurance that the lid is securely sealed on the housing body 24.
Referring to FIGS. 3-10B, the flame generation assembly includes the flame generation base 42 which has a plate portion 120 which is sized for insertion into the open interior 122 of the housing body 24. A pair of O-ring grooves 126, 128 receive O-rings 130, 131 formed of compliant material that seal the juncture 134 between the housing body 24 and the flame generation base and the juncture 136 between the lid and the flame generation base when the lid is closed.
A post 150 extends from the flame generation base 42 through the fuel reservoir 151 defined by the housing body 24 and flame generation base 42 toward the rearward end 152 of the housing base and has a threaded end 154 to which is attached the knob 32. As best shown in FIG. 10B, the post has an open interior configured as a bore 160 that defines a flint reservoir 162 for receiving flints 164. The flint reservoir having an axis α4. The bore may have interior threads 165 that receive a cap 168 with exterior threads 169. A spring 174 urges the flints 164 toward a flint wheel 180 that is rotatably attached to the flame generation base, such as be supports 182, 183 formed from the windshield and a rivet 185. The flint wheel having an axis of rotation of α5. See FIG. 7, for example. The flame generation base 42 has the fuel port 46 having an opening 190 extending into the open interior 192 of the housing body which may have filament material, such as rayon, to hold liquid lighter fluid. A wick 200 extends into the flame region and into the fluid reservoir 202 defined by the open interior 192 which may be filled with absorbent material 203. A felt pad 204 may be received in the fuel reservoir and fibrous absorbent material held in the reservoir. In embodiments, as best shown in FIG. 10A, the axis α4 of the flint reservoir is offset from the rotational axis α5 of the flint wheel. This provides an advantageous enhanced spark generation as the spark is angled more into the flame region 58 as illustrated by spark 210 in FIG. 10B, and there is more surface to surface contact between the flint and flint wheel compared to conventional arrangement where the axis intersect.
The knob 32 has an O-ring groove 221 and receives an O-ring 225 that seals the juncture 226 between the knob and housing body 24, precluding leakage of fluid. FIGS. 11 and 12 illustrate optional way to utilize the lighter, the lid, in embodiments, may provide enhanced wind protection. The knob seats comfortably in the palm of the user's hand.

The outer housing comprising a pair of outer housing components, a rear housing end cap 323 and a forward housing sleeve 324. A lid 326 connected to the housing sleeve by way of a hinge 328. A latching assembly 330 releasably secures the lid to a forward edge 331 of the housing sleeve 324 as shown in FIGS. 13-15, with the lighter 320 in a closed position or state. FIGS. 16 and 17 show the lighter in an open use position or state with the lid 326 rotated about the hinge 328 to lay along the outer surface 339 of the housing sleeve 324 revealing the flame generation assembly 340 attached to or extending from a flame generation base which in this embodiment is unitary with a main fuel containment housing body 341 and with components of the flame generation assembly 340 mounted to a flame generation base 342. The flame generation assembly includes a windshield 344, with opposing lateral walls 352, 353 extending from the flame generation base. An end wall 353 connects the two opposing lateral walls and the end wall 354 the two opposing lateral walls and the flame generation base 342 defining a flame outlet 359. The windscreen defining an open flame region 358. A fuel port 360 in the flame generation base 342 has an exposed wick 363 extending therefrom.
Referring in particular to FIGS. 13-20 and 25-27, the lid 326 may be configured as a flap with no side walls or minimal sidewalls extending around the margin 364 of the lid toward the housing sleeve 324. The lid 326 is attached to a housing sleeve 324 by hinge portions 372, 373 projecting upwardly from the housing sleeve 324 and are connected with hinge pin 375. A metal coil spring 376 can bias the lid 326 to the open position. The latching assembly 330 can comprise a spring latch member 380 with two latch ends 384, 385 two manual deflectable portions 387, 388, and an end portion 390. The spring latch member 380 held in place by a retention plate 392 having a recess 394 that conforms to the latch member 380 and exposes the two deflectable portions 387, 388 that are laterally exposed. A screw 389 secures the plate and the latch member 380 The latch ends 384, 385 are removably engageable with catch portions 396, 397 on the lid. The two latch ends 384, 385 having a lid retention position when the deflectable portions are not deflected where they are engaged with and capturing the catch portions on the lid 326 and a release position where the deflectable portions are squeezed inward moving the latch ends inward to an open region 399 between the catch portions 396, 397 such that the latch ends 384, 385 release the catch portions of the lid 326 allowing the lid to open under the bias provided by the spring 376. The spring latch member may be formed of spring steel. When released the lid rotates from the position of FIGS. 13-15 to the position of FIGS. 16 and 17 with the lid laying along the outer surface 339 of the housing sleeve with a rib 401 that may cooperate with and interface with an elongate groove 402 on the sleeve. This cooperation and interfacing reduces the overall height of the lighter and provides a more secure seating of the lid on the sleeve. Impacts or forces on the lid, when the lighter is open and the lid seated on the sleeve may be absorbed by the sleeve rather than being transmitted to the hinge with potential damage to the hinge. The lid further has a recess 404 on its inside surface 405 that receives a compliant seal 406 formed of compliant material. When the lid is closed and captured by the latch member, the compliant seal is compressed effectively sealing the lid to the sleeve.
