Definitions
- the present invention relates to incendiary devices configured to ignite cigarettes, cigars and pipes.
- lighters include refillable fuel reservoirs. When such a lighter is depleted of fuel it can be refilled using commercially available fuel. Unfortunately, the refueling process can sometimes be messy and dangerous. As fuel is transferred from a fuel source, such as a canister, into the lighter's fuel reservoir, some of the fuel may spill. The spilled fuel can not only stain fabrics and leave a foul smelling residue, but it is also highly flammable and could accidentally ignite causing injury or property damage.
- a fuel source such as a canister
- Refillable lighters are generally constructed of durable, long-lasting materials and are intended to remain in working order for many years. These lighters also generally include a multitude of moving mechanical parts. Unfortunately, these moving parts sometimes wear out, causing the lighter to become inoperative. Some of these moving parts are very small and/or difficult to remove from the lighter. Therefore, when a lighter breaks down it can be very difficult, time consuming and expensive to replace the worn out parts and restore the lighter to working order.
- one aspect of the present lighter is the realization that it would be beneficial to all users of refillable lighters to separate the lighter fuel from the user as much as possible.
- the user would be safer and there would be less of a likelihood of fuel staining any fabrics or leaving a foul smell behind.
- Another aspect of the present lighter is the realization that it would be beneficial to all users of refillable lighters to be able to replace worn out components of the lighters without the difficulty, delay and expense of repair procedures. For example, if a user could simply dispose of a worn out lighter component by quickly disassembling the lighter and replacing the worn out component with a new one, the user would be able to use his or her lighter again immediately instead of having to wait for a repair process to be completed by a professional. A do-it-yourself repair capability would also likely save the lighter user money in repair costs.

- FIG. 1 illustrates one embodiment of the present multi-component lighter 30.
- the lighter 30 includes a fuel cartridge 32 and a housing 34.
- the housing 34 includes an upper case 36 and a lower case 38.
- the housing may comprise only a single component.
- the fuel cartridge 32 could be integral with the lower case 38, or the upper case 36 may be used with the fuel cartridge 32 without the lower case 38.
- Figure 2 illustrates another embodiment of the present lighter 40.
- This embodiment is substantially identical to the embodiment of Figure 1, and includes a fuel cartridge 32 and an upper case 36.
- the lower case 42 includes a punch cutter 44 pivotably attached thereto. The structure and function of the cutter 44 are described in greater detail below.
- the lighter 30, 40 advantageously comprises two basic components, the housing 34 and the fuel cartridge 32.
- the housing 34 comprises an upper case 36 and a lower case 38, 42.
- the housing may comprise only one case.
- the housing 34 and the fuel cartridge 32 may be easily assembled and disassembled by the lighter user without the need to use any tools.
- the user can thus easily remove one or more components of the lighter and replace that component with a new one. For example, if the fuel cartridge is empty, the user can dispose of it and replace it with a new full one.
- the refilling process is thus much safer and faster and prevents fuel from staining fabrics or leaving a foul smell.
- a user could replace the upper case 36 if any portion of that component were to wear out or become damaged.
- the upper case includes several moving parts. With a typical prior art lighter including similar moving parts, if the lighter became inoperative a user would have to purchase a new lighter or have expensive and time consuming repairs performed by a professional. With the present lighter 30, 40, if the upper case 36 (or the lower case 38 or the fuel cartridge 32) becomes inoperative or unsightly for any reason, the user can purchase a replacement component and then perform a do-it-yourself repair by discarding the damaged component and replacing it with a new one. Such a do-it-yourself repair would likely be less expensive than purchasing an entire lighter, and could likely be completed in less time than repairs performed by a professional repair facility.
- the upper case 36 includes a cavity 43 that is sized and shaped to receive the fuel cartridge 32 in a sliding engagement.
- the lower case 38 also includes a cavity 46 that is sized and shaped to receive the fuel cartridge 32 and the upper case 36 in a sliding engagement. All three components 32, 36, 38 preferably engage one another in a friction fit, so that the components are not likely to spontaneously separate from one another.
- the fuel cartridge 32 may include one or more bosses and/or convexities and the upper case 36 may include one or more detents, concavities and/or apertures.
- the fuel cartridge 32 includes two convexities 48 on a front surface thereof ( Figure 1), and the upper case 36 includes two apertures 50 in a front surface thereof. Similarly located convexities and apertures may also be provided on rear surfaces of the fuel cartridge 32 and the upper case 36.
- the apertures 50 receive the convexities 48.
- one or more fastening members such as screws (not shown), may be used to further strengthen the connection between the fuel cartridge 32 and the upper case 36.
- a screw may extend through the upper case 36 and into the fuel cartridge 32. Preferably, however, the screw would not compromise the integrity of the fuel cartridge, which could cause fuel to leak.
- the upper case 36 may also include one or more bosses 51.
- bosses 51 In the illustrated embodiment, two spaced bosses 51 are provided on a front surface of the upper case 36, near a lower edge thereof. Similarly located bosses 51 may also be provided on a rear surface of the upper case 36.
- the bosses 51 engage inner surfaces of the lower case 38, 42.
- the bosses 51 may also provide a more snug fit between the upper case 36 and the lower case 38, 42, thereby lessening the chances that these two components could spontaneously separate. And, the bosses 51 may engage detents or depressions (not shown) in the inner surfaces of the lower case 38, 42 to further secure the lower case 38, 42 and the upper case 36 to one another.
- the upper case 36 may also include one or more raised ribs 53.
- the ribs serve similar functions as the bosses 51 illustrated in Figures 1 and 2. That is, they protect the surfaces of the upper case 36 and provide a more snug fit between the upper case 36 and the lower case 38, 42.
- each rib comprises an embossed, or raised, surface that extends upward in a substantially straight vertical line from adjacent a lower end of the upper case 36.
- upper and lower ends 55 of each rib 53 may slope toward the upper case 36. As the upper case 36 is slid into the lower case 38, the sloped surfaces 55 contact upper edges 57 of the lower case 38 and help to guide the upper case 36 into the lower case 38.
- three horizontally spaced and vertically oriented ribs 53 are provided on the front surface of the upper case 36.
- Three similarly spaced and oriented ribs may also be provided on a rear surface of the upper case 36.
- a further rib is provided on a left-side surface of the upper case 36.
- the ribs 53 could have other shapes and/or configurations, that fewer or more ribs could be provided, and that the ribs could be differently located.
- the rib 53 on the left-side surface may not be provided.
- the upper case 36 may include a tensioning spring 59.
- the tensioning spring comprises two oppositely extending, cantilevered leaf springs 61.
- the leaf springs 61 are formed from a flat plate 63 having two U-shaped voids 65. The open ends of the voids 65 face one another. A free end of each leaf spring includes a convexity 67.
- the convexities 67 extend outward from a right-side surface of the upper case 36, thereby creating an interference fit between the upper case 36 and the lower case 38.
- the leaf springs 61 are bent inward by contact between the convexities 67 and the inner surface of the lower case 38.
- the bent leaf springs 61 thus create a tensioning force that holds the upper case 36 snugly within the lower case 38.
- the tensioning spring 59 need not be provided.
- the fuel cartridge 32 further includes a cantilevered spring tab 52 extending from a right-side surface thereof.
- An upper end of the spring tab 52 adjoins a fuel reservoir portion 54 of the fuel cartridge 32, and a cantilevered portion extends generally downwardly therefrom.
- a right side of the spring tab 52 slopes outwardly and then inwardly as a thickness of the spring tab 52 increases and then decreases toward a free end 56 of the spring tab 52.
- a maximum thickness of the spring tab 52 occurs at a ridge 58 on the lower half thereof. The ridge 58 and the sloped surfaces to either side of the ridge 58 engage an opening 60 on a tongue 62 of the upper case 36, as shown in Figure 4.
- FIG 7 illustrates the upper case 36 and its related components.
- the upper case 36 comprises a rigid outer casing 70 that is shaped substantially as a rectangular parallelepiped and includes interior cavities that receive various components.
- the upper case 36 houses an electronic piezo 72 ( Figure 3) that produces a spark to ignite the lighter fuel and produce a flame.
- the structure and function of a typical electronic piezo, and its related components, is well known to those of ordinary skill in the art. Accordingly, the operation of some of the components of the present lighter will not be discussed in detail.
- the present lighter could include alternative apparatus for producing a spark.
- the lighter could include a flint and a metal spark wheel.
- An upper right-hand portion of the outer casing 70 receives a reciprocating ignition button 74 ( Figures 3, 7 and 13-16).
- the button 74 is mounted on a spring (not shown), which is located inside a housing 76 ( Figure 3).
- a spring not shown
- the spring returns the button 74 to the at rest configuration illustrated in Figure 3.
- An upper left-hand portion of the outer casing 70 receives a burner cylinder 78.
- a lower end 80 of the burner cylinder 78 receives fuel from the fuel cartridge 32 and discharges the vaporized fuel into the atmosphere through one or more flame holes 82 ( Figures 3 and 16) each time the ignition button 74 is depressed.
- a spark discharge unit 84 located adjacent the burner cylinder 78 produces a spark each time the ignition button 74 is depressed. The spark ignites the vaporized fuel to produce a flame that bums in a space just above the burner cylinder 78.
- Front and rear surfaces of the casing 70 may include openings 85 ( Figure 7) that enable air to pass through to the burner cylinder 78 to enhance the combustion there. However, as those of ordinary skill in the art will appreciate, the openings 85 need not be provided.
- the upper left-hand portion of the outer casing 70 also receives a hinged cover 86.
- the cover 86 is substantially L-shaped in profile.
- a lower portion thereof includes an aperture 88 ( Figure 7) that receives a pin 90 ( Figure 3).
- the pin 90 passes through the outer casing 70 and through the aperture 88 to pivotably secure the cover 86 to the upper case 36.
- a lever 92 actuates the cover 86 in response to movement of the ignition button 74. With reference to Figures 4 and 5, the lever 92 is pivotably mounted to the upper case 36 with a pin 94 in a manner similar to the cover 86.
- the button 74 moves a right-hand portion of the lever 92 downward, causing the lever 92 to pivot about the pin 94, which is disposed near a left-to-right center of the lever 92.
- a left-hand portion thereof moves upward and applies a force to the lower end of the cover 86.
- the applied force induces a rotation of the cover 86 about its pin 90 and moves the cover 86 to the open configuration Figure 5.
- the spring (not shown) urges the button 74 back upward to the at rest position, as shown in Figure 4.
- the cover 86 does the same.
- a right-hand portion of the outer casing 70 receives an interior support member 96 that locates and supports various components of the lighter 30.
- a right-hand portion of the support member 96 includes an elongate vertical cavity 98 that contains the piezo 72 and the housing 76 for the spring (not shown).
- a lower surface 100 of the support member 96 includes a female guide member in the form of a cavity 102 that receives a male guide member in the form of a prong 164 extending from the fuel cartridge 32, as explained in greater detail below.
- a tongue 62 extends downward from a lower right-hand corner of the support member 96 ( Figure 7).
- a left-side surface of the tongue 62 includes a groove 104 ( Figure 3) that receives and guides the spring tab 52 of the fuel cartridge 32, as described above.
- the tongue 62 also includes an opening 60 that receives the ridge 58 of the spring tab 52, as also described above.
- FIG 8 illustrates an exploded view of the fuel cartridge 32.
- the fuel cartridge 32 comprises a fuel reservoir 54 having an interior cavity 106 ( Figure 3) configured to store fuel in a liquid and/or gaseous phase.
- the fuel may be butane or any other suitable fuel.
- the fuel reservoir 54 comprises a lower portion 108 shaped substantially as a rectangular parallelepiped, and an upper portion 110 that is also shaped substantially as a rectangular parallelepiped.
- the fuel reservoir 54 may advantageously be made of molded plastic, so that the fuel reservoir 54 is relatively inexpensive to produce.
- the fuel reservoir 54 may also advantageously be made of a transparent or translucent material, so that an amount of liquid fuel contained within the fuel reservoir 54 is easily discernible through a visual inspection.
- a left-hand side of the fuel cartridge 32 includes an elongate vertical cavity 112 ( Figure 3) configured to receive a fuel transfer column 114.
- the fuel transfer column 114 which is shown in an exploded view in Figure 8, includes a tubular stem 116 configured to transmit fuel from the fuel reservoir 54 to the burner cylinder 78.
- the stem 116 includes external threads 118 that engage internal threads (not shown) in the elongate vertical cavity 112 to secure the stem 116 within the cavity.
- a flame height adjuster 120 is secured to a lower end of the stem 116, and a fuel outlet nozzle 122 is secured to an upper end of the stem 116. Rotation of the flame height adjuster 120 with respect to the stem 116 allows the user to adjust the flow rate of fuel through the fuel transfer column 114, thereby enabling adjustment of the size of the flame produced by the burner cylinder 78.
- the lower end of the stem 116 may also include a fuel inlet valve 124, as illustrated in Figure 3.
- the fuel inlet valve 124 enables additional fuel to be added to the fuel reservoir 54 in a manner well-known in the art. However, since the fuel cartridge 32 is removable and replaceable, the fuel inlet valve 124 need not be provided.
- the components of the fuel transfer column 114 may be made of one or more metals, such as brass or steel, for example. However, those of ordinary skill in the art will appreciate that the fuel transfer column 114 could be made of any suitable materials that preferably do not corrode or deteriorate in the presence of lighter fuel.
- Figure 10 illustrates the upper end of the stem 116 and the fuel outlet nozzle 122 in detail, with the nozzle 122 being shown in cross-section.
- the outlet nozzle 122 is configured to attenuate a pressure and/or velocity of fuel passing through the outlet nozzle 122.
- the nozzle 122 is substantially cylindrical and includes a narrow opening 126 approximately midway therethrough.
- the upper end of the stem 116 is also substantially cylindrical and includes first and second O-rings 128.
- a lower portion 130 of the nozzle 122 slides over the O-rings 128 in a friction fit.
- the O-rings 128 abut the inner surface 132 of the lower portion 130 of the nozzle 122 to seal the lower end of the nozzle 122 and prevent the escape of fuel therethrough.
- the upper end of the stem 116 further includes external threads 134 located above the O-rings 128.
- the inner surface 132 of the nozzle 122 includes internal threads 138 that engage the external threads 134 on the stem 116 to secure the nozzle 122 to the stem 116.
- the threaded engagement advantageously prevents the accidental separation of these two components. This feature is of particular advantage when the fuel cartridge 32 is removed from the housing 34 for any reason, since the nozzle 122 is relatively small, and could be misplaced. This feature is also of particular advantage where the fuel cartridge 32 is separately packaged as a replacement part for the lighter 30, 40. The securely held nozzle 122 is unlikely to be lost while the user replaces an empty fuel cartridge 32 with a full one.
- the nozzle 122 comprises a lower portion 130 and an upper portion 136 that are separate pieces. Those of ordinary skill in the art will appreciate that the nozzle 122 could be constructed of one unitary piece.
- the nozzle 122 may also include a fuel chip (not shown) that may help to attenuate the pressure and/or velocity of fuel passing through the outlet nozzle 122. Those of ordinary skill in the art will appreciate, however, that the fuel chip need not be provided.
- a lever 140 is pivotably attached to an upper end of the fuel cartridge 32.
- the lever 140 is illustrated in front elevation in Figure 8, and in a top plan view in Figure 9.
- the lever 140 includes a fulcrum 142 near a left-to-right center thereof.
- the fulcrum 142 comprises first and second cylindrical posts 144 ( Figure 9) that extend in opposite directions from front and rear surfaces, respectively, of the lever 140.
- the lever 140 further includes a horizontal portion 146 extending to the left of the fulcrum 142, and a diagonal portion 148 extending up and to the right of the fulcrum 142.
- the horizontal portion 146 is substantially U-shaped, including first and second spaced legs 150, and the diagonal portion 148 is substantially rectangular.
- an upper end of the fuel cartridge 32 includes spaced front and rear walls 152.
- the walls 152 comprise upward extensions of front and rear walls of the fuel reservoir 54. Only the front wall is visible in Figure 8.
- Each wall 152 includes an aperture 154 that pivotably receives one of the posts 144.
- Each aperture 154 opens to a top edge 156 of its respective wall 152.
- a distance between first and second sides of the opening 158 is slightly less than a diameter of either post 144.
- the lever 140 thus snaps onto the fuel reservoir 54 as the posts 144 slide through the narrow openings 158 and into the apertures 154.
- the lever 140 is likewise removable from the fuel reservoir 54 by popping the posts 144 back out of the apertures 154 through the narrow openings 158.
- the stem 116 includes a narrow neck portion 160 below the O-rings 128. With reference to Figures 3 and 4, the neck 160 seats between the legs 150 of the lever 140.
- a right-hand portion 162 of the lever 92 pushes downward on the diagonal portion 148 of the lever 140.
- the lever 140 thus pivots about its posts 144 and the legs 150 pivot upward, drawing the upper portion of the stem 116 upward.
- the upper portion of the stem 116 moves upward fuel flows from the reservoir 54, through the fuel transfer column 114 and into the burner cylinder 78.
- the illustrated lever 140 is advantageously constructed of one piece.
- the lever 140 is thus less expensive to produce than levers made of multiple pieces.
- the lever 140 may also be made of molded plastic, which further reduces the cost of producing the lever 140.
- upper surfaces of the fuel cartridge 32 include first and second male guide members 164.
- Each male guide member 164 is shaped as a prong, including a substantially cylindrical base portion extending from the fuel cartridge 32, and a substantially conical portion extending upward from the base portion and terminating in a rounded tip.
- each prong 164 is configured to mate with one of first and second female guide members 102, 166 in the fuel cartridge 32.
- the first female guide member 102 comprises a substantially cylindrical cavity
- the second female guide member 166 comprises an aperture.
- the female guide members 102, 166 could have other configurations.
- the positions of the male and female guide members may be reversed partially or entirely.
- each prong 164 enters its respective mating female guide member 102, 166. Because the pointed tip of each prong 164 is substantially smaller in diameter than its respective female guide member 102, 166, each prong 164 is very likely to locate its respective female guide member 102, 166 even if the fuel cartridge 32 and the upper case 36 are misaligned as the two components are brought together. Once the tip of each prong 164 has properly located its female guide member 102, 166, the tapering ends of the prongs 164 help to properly align the fuel cartridge 32 with the upper case 36 as the components are slid together all the way.
- a method of refueling the present lighter 30, 40 comprises the step of replacing an empty, or partially empty, fuel cartridge 32 with a full one, or a partially full one.

- an empty fuel cartridge 32 can be replaced with a commercially available full one.
- the replacement process keeps the user safely separated from the flammable and foul smelling fuel, which is at all times contained inside the fuel reservoir.
- the replacement process involves the steps of removing the fuel outlet nozzle 122 from the empty fuel cartridge 32 and securing it to the new fuel cartridge 32.
- Commercially available replacement fuel cartridges may not include the fuel outlet nozzle 122, which may advantageously reduce the retail price of the replacement fuel cartridge.
- the fuel outlet nozzle 122 may contain a fuel chip and/or other small components that cause it to be relatively expensive to produce.

Abstract
The present lighter (30,40) includes two basic components, a housing (34) and a fuel cartridge (32). The housing may comprise multiple pieces. The fuel cartridge is easy to remove from the housing without the use of any tools. Thus, an empty fuel cartridge (32) can quickly be replaced with a full one by the user. Replacing the fuel cartridge, rather than refilling it, prevents the user from coming into contact with lighter fuel. The housing (34) and the fuel cartridge (32) are each relatively inexpensive to mass produce. Thus, a worn or damaged housing may be removed from the lighter by the user and replaced with a new housing. The disposability and replaceability of the lighter components makes repairs to the lighter quick and inexpensive. All or part of the housing may also be replaced with a housing having a different outward appearance. A user can thus change the appearance of his or her lighter by changing housings, rather than having to purchase multiple lighters. The housing may include surface features, such as bosses (51), ribs (53) and/or tensioning springs (59), to tighten a fit of the housing and prevent spontaneous separation. The surface features may also protect the appearance of the housing.
Description
- This application claims priority of
US application Serial No. 11/505,250, filed on August 15, 2006 US application Serial No. 11/517,824 filed on September 8,2006 - The present invention relates to incendiary devices configured to ignite cigarettes, cigars and pipes.
- Many high-end lighters include refillable fuel reservoirs. When such a lighter is depleted of fuel it can be refilled using commercially available fuel. Unfortunately, the refueling process can sometimes be messy and dangerous. As fuel is transferred from a fuel source, such as a canister, into the lighter's fuel reservoir, some of the fuel may spill. The spilled fuel can not only stain fabrics and leave a foul smelling residue, but it is also highly flammable and could accidentally ignite causing injury or property damage.
- Refillable lighters are generally constructed of durable, long-lasting materials and are intended to remain in working order for many years. These lighters also generally include a multitude of moving mechanical parts. Unfortunately, these moving parts sometimes wear out, causing the lighter to become inoperative. Some of these moving parts are very small and/or difficult to remove from the lighter. Therefore, when a lighter breaks down it can be very difficult, time consuming and expensive to replace the worn out parts and restore the lighter to working order.
- In light of the above shortcomings of prior art lighters, one aspect of the present lighter is the realization that it would be beneficial to all users of refillable lighters to separate the lighter fuel from the user as much as possible. Thus, if a user could refill his or her lighter with only a very low risk that fuel might be spilled, the user would be safer and there would be less of a likelihood of fuel staining any fabrics or leaving a foul smell behind.
- Another aspect of the present lighter is the realization that it would be beneficial to all users of refillable lighters to be able to replace worn out components of the lighters without the difficulty, delay and expense of repair procedures. For example, if a user could simply dispose of a worn out lighter component by quickly disassembling the lighter and replacing the worn out component with a new one, the user would be able to use his or her lighter again immediately instead of having to wait for a repair process to be completed by a professional. A do-it-yourself repair capability would also likely save the lighter user money in repair costs.

- Figure 1 illustrates one embodiment of the present multi-component lighter 30. The lighter 30 includes a
fuel cartridge 32 and ahousing 34. In the illustrated embodiment, thehousing 34 includes anupper case 36 and alower case 38. However, those of skill in the art will appreciate that in other embodiments the housing may comprise only a single component. For example, thefuel cartridge 32 could be integral with thelower case 38, or theupper case 36 may be used with thefuel cartridge 32 without thelower case 38. - Figure 2 illustrates another embodiment of the present lighter 40. This embodiment is substantially identical to the embodiment of Figure 1, and includes a
fuel cartridge 32 and anupper case 36. However, thelower case 42 includes apunch cutter 44 pivotably attached thereto. The structure and function of thecutter 44 are described in greater detail below. - In each of the embodiments of Figures 1 and 2, the lighter 30, 40 advantageously comprises two basic components, the
housing 34 and thefuel cartridge 32. In addition, in the illustrated embodiments thehousing 34 comprises anupper case 36 and alower case - As explained in detail below, the
housing 34 and thefuel cartridge 32 may be easily assembled and disassembled by the lighter user without the need to use any tools. The user can thus easily remove one or more components of the lighter and replace that component with a new one. For example, if the fuel cartridge is empty, the user can dispose of it and replace it with a new full one. By refilling the lighter in this manner, the user never comes into contact with lighter fuel. The refilling process is thus much safer and faster and prevents fuel from staining fabrics or leaving a foul smell. - As another example, a user could replace the
upper case 36 if any portion of that component were to wear out or become damaged. The upper case includes several moving parts. With a typical prior art lighter including similar moving parts, if the lighter became inoperative a user would have to purchase a new lighter or have expensive and time consuming repairs performed by a professional. With the present lighter 30, 40, if the upper case 36 (or thelower case 38 or the fuel cartridge 32) becomes inoperative or unsightly for any reason, the user can purchase a replacement component and then perform a do-it-yourself repair by discarding the damaged component and replacing it with a new one. Such a do-it-yourself repair would likely be less expensive than purchasing an entire lighter, and could likely be completed in less time than repairs performed by a professional repair facility. - With reference to Figures 3 and 4, the
upper case 36 includes a cavity 43 that is sized and shaped to receive thefuel cartridge 32 in a sliding engagement. Thelower case 38 also includes acavity 46 that is sized and shaped to receive thefuel cartridge 32 and theupper case 36 in a sliding engagement. All threecomponents fuel cartridge 32 may include one or more bosses and/or convexities and theupper case 36 may include one or more detents, concavities and/or apertures. In the illustrated embodiment, thefuel cartridge 32 includes twoconvexities 48 on a front surface thereof (Figure 1), and theupper case 36 includes twoapertures 50 in a front surface thereof. Similarly located convexities and apertures may also be provided on rear surfaces of thefuel cartridge 32 and theupper case 36. When thefuel cartridge 32 and theupper case 36 are brought together as shown in Figures 4 and 6, theapertures 50 receive theconvexities 48. The engagement of these features further strengthens the connection between thefuel cartridge 32 and theupper case 36. If desired, one or more fastening members, such as screws (not shown), may be used to further strengthen the connection between thefuel cartridge 32 and theupper case 36. For example, a screw may extend through theupper case 36 and into thefuel cartridge 32. Preferably, however, the screw would not compromise the integrity of the fuel cartridge, which could cause fuel to leak. - With reference to Figures 1 and 2, the
upper case 36 may also include one ormore bosses 51. In the illustrated embodiment, two spacedbosses 51 are provided on a front surface of theupper case 36, near a lower edge thereof. Similarly locatedbosses 51 may also be provided on a rear surface of theupper case 36. Thebosses 51 engage inner surfaces of thelower case upper case 36 is slid into or out of thelower case upper case 36 are protected against scratches that could be caused by contact with inner surfaces of thelower case bosses 51 thus prolong the new appearance of theupper case 36. Thebosses 51 may also provide a more snug fit between theupper case 36 and thelower case bosses 51 may engage detents or depressions (not shown) in the inner surfaces of thelower case lower case upper case 36 to one another. - With reference to Figures 22 and 23, the
upper case 36 may also include one or more raisedribs 53. The ribs serve similar functions as thebosses 51 illustrated in Figures 1 and 2. That is, they protect the surfaces of theupper case 36 and provide a more snug fit between theupper case 36 and thelower case upper case 36. With reference to Figure 23, upper and lower ends 55 of eachrib 53 may slope toward theupper case 36. As theupper case 36 is slid into thelower case 38, thesloped surfaces 55 contactupper edges 57 of thelower case 38 and help to guide theupper case 36 into thelower case 38. - In the illustrated embodiment, three horizontally spaced and vertically oriented
ribs 53 are provided on the front surface of theupper case 36. Three similarly spaced and oriented ribs may also be provided on a rear surface of theupper case 36. A further rib is provided on a left-side surface of theupper case 36. Those of ordinary skill in the art will appreciate that theribs 53 could have other shapes and/or configurations, that fewer or more ribs could be provided, and that the ribs could be differently located. For example, therib 53 on the left-side surface may not be provided. - With reference to Figure 23, the
upper case 36 may include atensioning spring 59. In the illustrated embodiment, the tensioning spring comprises two oppositely extending, cantilevered leaf springs 61. The leaf springs 61 are formed from aflat plate 63 having twoU-shaped voids 65. The open ends of thevoids 65 face one another. A free end of each leaf spring includes aconvexity 67. With reference to Figure 22, theconvexities 67 extend outward from a right-side surface of theupper case 36, thereby creating an interference fit between theupper case 36 and thelower case 38. Thus, when theupper case 36 is positioned within thelower case 38, theleaf springs 61 are bent inward by contact between the convexities 67 and the inner surface of thelower case 38. Thebent leaf springs 61 thus create a tensioning force that holds theupper case 36 snugly within thelower case 38. Those of ordinary skill in the art will appreciate that thetensioning spring 59 need not be provided. - With reference to Figure 3, the
fuel cartridge 32 further includes a cantileveredspring tab 52 extending from a right-side surface thereof. An upper end of thespring tab 52 adjoins afuel reservoir portion 54 of thefuel cartridge 32, and a cantilevered portion extends generally downwardly therefrom. Beginning near a vertical center thereof, a right side of thespring tab 52 slopes outwardly and then inwardly as a thickness of thespring tab 52 increases and then decreases toward afree end 56 of thespring tab 52. A maximum thickness of thespring tab 52 occurs at aridge 58 on the lower half thereof. Theridge 58 and the sloped surfaces to either side of theridge 58 engage anopening 60 on atongue 62 of theupper case 36, as shown in Figure 4. With reference to Figure 3, as thefuel cartridge 32 is slid into the cavity 43 in theupper case 36, the upper slopedsurface 64 on thespring tab 52 engages alower edge 66 of thetongue 62, and thespring tab 52 flexes as thefuel cartridge 32 is slid further into theupper case 36. As thefuel cartridge 32 and theupper case 36 near the fully engaged configuration of Figure 4, theridge 58 passes alower edge 68 of theopening 60 in thetongue 62 and thespring tab 52 pops outwardly as theridge 58 pops into the opening in thetongue 62. The engagement of these features further strengthens the connection between thefuel cartridge 32 and theupper case 36. - Figure 7 illustrates the
upper case 36 and its related components. Theupper case 36 comprises a rigidouter casing 70 that is shaped substantially as a rectangular parallelepiped and includes interior cavities that receive various components. In the illustrated embodiment, theupper case 36 houses an electronic piezo 72 (Figure 3) that produces a spark to ignite the lighter fuel and produce a flame. The structure and function of a typical electronic piezo, and its related components, is well known to those of ordinary skill in the art. Accordingly, the operation of some of the components of the present lighter will not be discussed in detail. Those of ordinary skill in the art will appreciate, however, that the present lighter could include alternative apparatus for producing a spark. For example, the lighter could include a flint and a metal spark wheel. - An upper right-hand portion of the
outer casing 70 receives a reciprocating ignition button 74 (Figures 3, 7 and 13-16). Thebutton 74 is mounted on a spring (not shown), which is located inside a housing 76 (Figure 3). When the lighter user depresses and releases thebutton 74, the spring returns thebutton 74 to the at rest configuration illustrated in Figure 3. An upper left-hand portion of theouter casing 70 receives aburner cylinder 78. Alower end 80 of theburner cylinder 78 receives fuel from thefuel cartridge 32 and discharges the vaporized fuel into the atmosphere through one or more flame holes 82 (Figures 3 and 16) each time theignition button 74 is depressed. Aspark discharge unit 84 located adjacent theburner cylinder 78 produces a spark each time theignition button 74 is depressed. The spark ignites the vaporized fuel to produce a flame that bums in a space just above theburner cylinder 78. Front and rear surfaces of thecasing 70 may include openings 85 (Figure 7) that enable air to pass through to theburner cylinder 78 to enhance the combustion there. However, as those of ordinary skill in the art will appreciate, theopenings 85 need not be provided. - The upper left-hand portion of the
outer casing 70 also receives a hingedcover 86. Thecover 86 is substantially L-shaped in profile. A lower portion thereof includes an aperture 88 (Figure 7) that receives a pin 90 (Figure 3). Thepin 90 passes through theouter casing 70 and through theaperture 88 to pivotably secure thecover 86 to theupper case 36. Alever 92 actuates thecover 86 in response to movement of theignition button 74. With reference to Figures 4 and 5, thelever 92 is pivotably mounted to theupper case 36 with apin 94 in a manner similar to thecover 86. When the lighter 30 user depresses thebutton 74, as shown in Figure 5, thebutton 74 moves a right-hand portion of thelever 92 downward, causing thelever 92 to pivot about thepin 94, which is disposed near a left-to-right center of thelever 92. As thelever 92 pivots, a left-hand portion thereof moves upward and applies a force to the lower end of thecover 86. The applied force induces a rotation of thecover 86 about itspin 90 and moves thecover 86 to the open configuration Figure 5. When the user releases thebutton 74, the spring (not shown) urges thebutton 74 back upward to the at rest position, as shown in Figure 4. As thebutton 74 moves upward thelever 92 pivots back toward its at rest position, and thecover 86 does the same. - A right-hand portion of the
outer casing 70 receives aninterior support member 96 that locates and supports various components of the lighter 30. For example, with reference to Figure 3, a right-hand portion of thesupport member 96 includes an elongatevertical cavity 98 that contains the piezo 72 and thehousing 76 for the spring (not shown). Alower surface 100 of thesupport member 96 includes a female guide member in the form of acavity 102 that receives a male guide member in the form of aprong 164 extending from thefuel cartridge 32, as explained in greater detail below. Atongue 62 extends downward from a lower right-hand corner of the support member 96 (Figure 7). A left-side surface of thetongue 62 includes a groove 104 (Figure 3) that receives and guides thespring tab 52 of thefuel cartridge 32, as described above. Thetongue 62 also includes anopening 60 that receives theridge 58 of thespring tab 52, as also described above. - Figure 8 illustrates an exploded view of the
fuel cartridge 32. Thefuel cartridge 32 comprises afuel reservoir 54 having an interior cavity 106 (Figure 3) configured to store fuel in a liquid and/or gaseous phase. For example, the fuel may be butane or any other suitable fuel. In the illustrated embodiment, thefuel reservoir 54 comprises alower portion 108 shaped substantially as a rectangular parallelepiped, and anupper portion 110 that is also shaped substantially as a rectangular parallelepiped. Thefuel reservoir 54 may advantageously be made of molded plastic, so that thefuel reservoir 54 is relatively inexpensive to produce. Thefuel reservoir 54 may also advantageously be made of a transparent or translucent material, so that an amount of liquid fuel contained within thefuel reservoir 54 is easily discernible through a visual inspection. - A left-hand side of the
fuel cartridge 32 includes an elongate vertical cavity 112 (Figure 3) configured to receive afuel transfer column 114. Thefuel transfer column 114, which is shown in an exploded view in Figure 8, includes atubular stem 116 configured to transmit fuel from thefuel reservoir 54 to theburner cylinder 78. In the illustrated embodiment, thestem 116 includesexternal threads 118 that engage internal threads (not shown) in the elongatevertical cavity 112 to secure thestem 116 within the cavity. - A
flame height adjuster 120 is secured to a lower end of thestem 116, and afuel outlet nozzle 122 is secured to an upper end of thestem 116. Rotation of theflame height adjuster 120 with respect to thestem 116 allows the user to adjust the flow rate of fuel through thefuel transfer column 114, thereby enabling adjustment of the size of the flame produced by theburner cylinder 78. The lower end of thestem 116 may also include afuel inlet valve 124, as illustrated in Figure 3. Thefuel inlet valve 124 enables additional fuel to be added to thefuel reservoir 54 in a manner well-known in the art. However, since thefuel cartridge 32 is removable and replaceable, thefuel inlet valve 124 need not be provided. The components of thefuel transfer column 114 may be made of one or more metals, such as brass or steel, for example. However, those of ordinary skill in the art will appreciate that thefuel transfer column 114 could be made of any suitable materials that preferably do not corrode or deteriorate in the presence of lighter fuel. - Figure 10 illustrates the upper end of the
stem 116 and thefuel outlet nozzle 122 in detail, with thenozzle 122 being shown in cross-section. Theoutlet nozzle 122 is configured to attenuate a pressure and/or velocity of fuel passing through theoutlet nozzle 122. Thenozzle 122 is substantially cylindrical and includes anarrow opening 126 approximately midway therethrough. The upper end of thestem 116 is also substantially cylindrical and includes first and second O-rings 128. Alower portion 130 of thenozzle 122 slides over the O-rings 128 in a friction fit. The O-rings 128 abut theinner surface 132 of thelower portion 130 of thenozzle 122 to seal the lower end of thenozzle 122 and prevent the escape of fuel therethrough. - The upper end of the
stem 116 further includesexternal threads 134 located above the O-rings 128. Theinner surface 132 of thenozzle 122 includesinternal threads 138 that engage theexternal threads 134 on thestem 116 to secure thenozzle 122 to thestem 116. The threaded engagement advantageously prevents the accidental separation of these two components. This feature is of particular advantage when thefuel cartridge 32 is removed from thehousing 34 for any reason, since thenozzle 122 is relatively small, and could be misplaced. This feature is also of particular advantage where thefuel cartridge 32 is separately packaged as a replacement part for the lighter 30, 40. The securely heldnozzle 122 is unlikely to be lost while the user replaces anempty fuel cartridge 32 with a full one. - In the illustrated embodiment, the
nozzle 122 comprises alower portion 130 and anupper portion 136 that are separate pieces. Those of ordinary skill in the art will appreciate that thenozzle 122 could be constructed of one unitary piece. Thenozzle 122 may also include a fuel chip (not shown) that may help to attenuate the pressure and/or velocity of fuel passing through theoutlet nozzle 122. Those of ordinary skill in the art will appreciate, however, that the fuel chip need not be provided. - With further reference to Figure 8, a
lever 140 is pivotably attached to an upper end of thefuel cartridge 32. Thelever 140 is illustrated in front elevation in Figure 8, and in a top plan view in Figure 9. With reference to Figure 8, thelever 140 includes afulcrum 142 near a left-to-right center thereof. Thefulcrum 142 comprises first and second cylindrical posts 144 (Figure 9) that extend in opposite directions from front and rear surfaces, respectively, of thelever 140. With reference to Figure 8, thelever 140 further includes ahorizontal portion 146 extending to the left of thefulcrum 142, and adiagonal portion 148 extending up and to the right of thefulcrum 142. In top plan view (Figure 9), thehorizontal portion 146 is substantially U-shaped, including first and second spacedlegs 150, and thediagonal portion 148 is substantially rectangular. - With reference to Figure 8, an upper end of the
fuel cartridge 32 includes spaced front andrear walls 152. Thewalls 152 comprise upward extensions of front and rear walls of thefuel reservoir 54. Only the front wall is visible in Figure 8. Eachwall 152 includes an aperture 154 that pivotably receives one of theposts 144. Each aperture 154 opens to a top edge 156 of itsrespective wall 152. At theopening 158, a distance between first and second sides of theopening 158 is slightly less than a diameter of eitherpost 144. Thelever 140 thus snaps onto thefuel reservoir 54 as theposts 144 slide through thenarrow openings 158 and into the apertures 154. Thelever 140 is likewise removable from thefuel reservoir 54 by popping theposts 144 back out of the apertures 154 through thenarrow openings 158. - With reference to Figure 10, the
stem 116 includes anarrow neck portion 160 below the O-rings 128. With reference to Figures 3 and 4, theneck 160 seats between thelegs 150 of thelever 140. When the user depresses theignition button 74, as shown in Figure 5, a right-hand portion 162 of thelever 92 pushes downward on thediagonal portion 148 of thelever 140. Thelever 140 thus pivots about itsposts 144 and thelegs 150 pivot upward, drawing the upper portion of thestem 116 upward. When the upper portion of thestem 116 moves upward fuel flows from thereservoir 54, through thefuel transfer column 114 and into theburner cylinder 78. - The illustrated
lever 140 is advantageously constructed of one piece. Thelever 140 is thus less expensive to produce than levers made of multiple pieces. Thelever 140 may also be made of molded plastic, which further reduces the cost of producing thelever 140. - With reference to Figures 3 and 8, upper surfaces of the
fuel cartridge 32 include first and secondmale guide members 164. Eachmale guide member 164 is shaped as a prong, including a substantially cylindrical base portion extending from thefuel cartridge 32, and a substantially conical portion extending upward from the base portion and terminating in a rounded tip. Those of ordinary skill in the art will appreciate that themale guide members 164 could have other configurations. With reference to Figures 3 and 4, eachprong 164 is configured to mate with one of first and secondfemale guide members fuel cartridge 32. In the illustrated embodiment, the firstfemale guide member 102 comprises a substantially cylindrical cavity, and the secondfemale guide member 166 comprises an aperture. Those of ordinary skill in the art will appreciate that thefemale guide members - With further reference to Figures 3 and 4, as the
fuel cartridge 32 is slid into theupper case 36, the pointed tip of eachprong 164 enters its respective matingfemale guide member prong 164 is substantially smaller in diameter than its respectivefemale guide member prong 164 is very likely to locate its respectivefemale guide member fuel cartridge 32 and theupper case 36 are misaligned as the two components are brought together. Once the tip of eachprong 164 has properly located itsfemale guide member prongs 164 help to properly align thefuel cartridge 32 with theupper case 36 as the components are slid together all the way. - In one embodiment, a method of refueling the present lighter 30, 40 comprises the step of replacing an empty, or partially empty,
fuel cartridge 32 with a full one, or a partially full one. The user first removes thelower case empty fuel cartridge 32 from theupper case 36. The user can then discard thedisposable fuel cartridge 32 and replace it with a new one that is full of fuel.Pre-filled fuel cartridges 32 may be available at retail outlets, so that the process of refueling the present lighter 30, 40 does not require the use of a fuel source, such as a canister, or the transfer of fuel from the fuel source into the fuel reservoir. As discussed above, the process of transferring fuel from a source container into a fuel reservoir can be messy and dangerous. With the present lighter anempty fuel cartridge 32 can be replaced with a commercially available full one. The replacement process keeps the user safely separated from the flammable and foul smelling fuel, which is at all times contained inside the fuel reservoir. In one embodiment, the replacement process involves the steps of removing thefuel outlet nozzle 122 from theempty fuel cartridge 32 and securing it to thenew fuel cartridge 32. Commercially available replacement fuel cartridges may not include thefuel outlet nozzle 122, which may advantageously reduce the retail price of the replacement fuel cartridge. For example, thefuel outlet nozzle 122 may contain a fuel chip and/or other small components that cause it to be relatively expensive to produce. In certain embodiments, however, commercially available replacement fuel cartridges may include thefuel outlet nozzle 122, so that the method of replacing an empty fuel cartridge may not include the steps of removing thefuel outlet nozzle 122 from theempty fuel cartridge 32 and securing it to thenew fuel cartridge 32. - In another embodiment, a method of refueling the present lighter 30, 40 comprises the step of adding fuel to the fuel reservoir by transferring the fuel from a fuel source, such as a canister, into the fuel reservoir through the
fuel inlet valve 124. In this embodiment, there is no need to remove thelower case door 178 on the lighter 40. The user simply positions the fuel source with respect to thefuel inlet valve 124 so that the fuel may be transferred therethrough. For example, the fuel source may include a nozzle that engages thefuel inlet valve 124 and injects fuel therethrough. Such fuel sources are well-known in the art and will not be described in detail here. - Figures 11 and 12 illustrate the
lower case 38 of the lighter 30 of Figure 1. In the illustrated embodiment, thelower case 38 is shaped substantially as a rectangular parallelepiped with an open top. Those of ordinary skill in the art will appreciate that the illustrated shape is merely one design choice, and that housings having different shapes are entirely within the scope of the claims herein. With reference to Figure 11, in the illustrated embodiment afront wall 168 of thelower case 38 includes first and secondair inlet openings 170 near an upper left corner thereof. Similar openings may be included on a rear wall of thelower case 38. Theopenings 170 are substantially oval, although any other shape could be used. When theignition button 74 of the lighter 30 is depressed and fuel is flowing to theburner cylinder 78, air flows through theair inlets 170 to theburner cylinder 78 to enhance the combustion of the fuel. Those of ordinary skill in the art will appreciate that theair inlets 170 need not be included. - With reference to Figure 12, in the illustrated embodiment a
left side wall 172 of thelower case 38 includes afuel viewing window 174 that enables easy viewing of a level of fuel in thefuel reservoir 54. The lighter user may thus easily discern how much fuel is left in his or her lighter 30 without disassembling the lighter 30. In the illustrated embodiment, thefuel viewing window 174 comprises an oval-shaped aperture. However, those of ordinary skill in the art will appreciate that the aperture could have any shape, such as round or elliptical. Alternatively, a fuel viewing window may not be provided. - In one embodiment the
lower case 38 is constructed of a metal, such as stainless steel, chrome-plated steel or anodized aluminum. Thelower case 38 may also be constructed of other suitable materials, such as high-strength plastic or ceramic. Thelower case 38 may have a smooth outer surface, as shown, or it may include a surface texture or pattern. Thelower case 38 may also be any of a variety of colors, and/or include a logo or emblem. In one embodiment, a first lower case having a first appearance characteristic, such as a silver color, may be quickly replaced with a second lower case having a second appearance characteristic, such as a gold color. Lower cases of different colors, textures, etc. may be sold at retail outlets so that lighter owners can customize their own lighter 30 by merely replacing one lower case with another. In this manner, a given lighter 30 may be easily and inexpensively converted to match different outfits, or to be suited for certain occasions, such as a golf outing or fishing trip, for example, all without the unnecessary expense of purchasing multiple lighters. A lighter owner simply purchases multiple lower cases to use as he or she sees fit. - With reference to Figure 3, which illustrates the
lower case 38 in cross-section, a lower surface of thelower case 38 includes anaperture 176. Theaperture 176 is aligned with the fuel inlet valve 124 (Figure 17) so that the lighter user may refill thefuel reservoir 54 without disassembling the lighter 30. In the illustrated embodiment, theaperture 176 is round and is of a sufficient depth so that theflame height adjuster 120 does not protrude from the lower surface of the lighter 30 (Figure 4). However, those of ordinary skill in the art will appreciate that theaperture 176 could have any shape and that theflame height adjuster 120 may protrude from the lower surface of the lighter 30 or may be further recessed than as shown. Those of ordinary skill in the art will further appreciate that thelower case 38 need not include any fuel access aperture at all. - Figures 18-21 illustrate the lighter 40 shown in Figure 2, which includes a hinged
punch cutter 44. With reference to Figure 19, adoor 178 is hinged to a lower end of thelower case 38 with a hinge pin (not shown). In the illustrated embodiment, the hinge pin is located near a lower right corner of thelower case 38, but those of ordinary skill in the art will appreciate that the hinge pin and hinge mechanism could be located anywhere on thelower case 38. - The
door 178 includes anouter surface 180, which forms an outward facing surface of thelower case 38 when thedoor 178 is in the closed position shown in Figure 18, and aninner surface 182. Acylindrical punch cutter 44 extends from theinner surface 182. Anedge 184 of thecutter 44 spaced from theinner surface 182 is sharpened and is configured to remove a plug of wrapper and tobacco from an end of a cigar in a manner well-known in the art. A lower end of thelower case 38 includes a recess 186 (Figure 21) into which thecutter 44 extends when thedoor 178 is in the closed position shown in Figure 18. - The
door 178 may be pivotable through 180° with respect to thelower case 38 as shown, or it may be pivotable through a smaller or larger angle with respect to thelower case 38. With reference to Figure 21, a leaf spring 188 extends substantially perpendicularly from a lower surface of thelower case 38 within therecess 186, and is located near an end of thelower case 38 opposite thehinge 190. The leaf spring 188 engages acatch 192 on thedoor 178 to secure thedoor 178 in the closed position. An end of thedoor 178 opposite the hinge includes aboss 194 that provides a gripping surface for the user to open thedoor 178. By applying light pressure on theboss 194 with his or her finger, the user can overcome the holding force of the leaf spring 188 to flip open thedoor 178. A lower surface of thelower case 38, which is located within the recess, may include anaperture 196 that enables access to thefuel inlet valve 124, as described above with respect to the lighter 30. Those of ordinary skill in the art will appreciate that the fuelinlet access aperture 196 need not be provided. - The present lighter 30, 40 advantageously lacks a fuel hose or other components that can be difficult to align as the lighter is assembled. Some prior art lighters include a multitude of small components, and properly arranging and aligning all of these components is a difficult process that makes it very undesirable to disassemble the lighter. With the present lighter 30, 40, by contrast, the major components can be quickly and easily aligned and slid together to complete the assembly. For example, the
fuel outlet nozzle 122 and thelower end 80 of theburner cylinder 78 automatically align with one another as thefuel cartridge 32 is slid into theupper case 36. And since thefuel outlet nozzle 122 and theburner cylinder 78 are separate components, thefuel outlet nozzle 122 can be quickly and easily replaced if it is damaged. - Those of ordinary skill in the art will appreciate that the above embodiments are merely examples. Each embodiment has been described as having components having particular shapes and being located in particular areas. However, many other configurations are possible. For example, certain components may be differently shaped, may be located in different places, or may be omitted entirely. Similarly, additional components beyond those described may be included. None of the embodiments disclosed above should be interpreted as limiting the scope of the claims herein.
- The above presents a description of the best mode contemplated for the present multi-component lighter, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains to make and use this lighter. This lighter is, however, susceptible to modifications and alternate constructions from that discussed above that are fully equivalent. Consequently, this lighter is not limited to the particular embodiments disclosed. On the contrary, this lighter covers all modifications and alternate constructions coming within the spirit and scope of the lighter as generally expressed by the following claims, which particularly point out and distinctly claim the subject matter of the lighter.
