Description Of The Prior Art
Liquid fuel burning cigarette lighters generally include reservoirs within the lighter housings to contain the fuel and prevent inadvertent leaking. Numerous types of mechanisms and methods are known to release the fuel from the reservoirs in a controlled manner and to ignite the fuel for lighting a cigarette, cigar, or smoking pipe, however, there exists a need for removing the fuel cartridge from the lighter safely.
Numerous innovations for cigarette lighter usable devices have been provided in the prior art, which will be described below in chronological order to show advancement in the art, and which are incorporated herein in their entirety by reference thereto. Even though these innovations may be suitable for the specific individual purposes to which they address, nevertheless, they differ from the embodiments of the present invention.
U.S. Pat. No. 2,710,533—issued to Fischer et al. on Jun. 14, 1955 in U.S. class 67 and subclass 7.1—teaches a ignition lighter mechanism that can be attached to a cartridge containing a liquified fuel under pressure, such as, butane, propane, and similar fuels that are adapted to turn into a gas upon being released into the atmosphere from the reservoir or container. A feature resides in the combination of a cartridge that carries a supply of liquified fuel, and the neck of which, is threaded so as to receive the lighter unit that includes a fuel release valve that permits the fuel from the cartridge to leak slowly through the same, a snufier cap, and a pyrophoric flint, and abrading wheel to direct a spark over the nozzle of the lighter unit. This combination of elements including mainly the cartridge holding a supply of compressed fuel for the flame of the lighter and the lighter unit provide the essential elements of the combination that produce a lighter, either of the pocket type or the desk type.
U.S. Pat. No. 4,330,954—issued to Lonsmin on May 25, 1982 in U.S. class 40 and subclass 486—teaches a cigarette lighter cover that is a novelty sleeve for the cigarette lighter, and which has a tubular body portion with a hollow interior space sized to receive the body of the cigarette lighter of conventional design. One end of the body portion is closed off to form a bottom end of the sleeve. The other end of the body portion is open to receive the cigarette lighter. An image-presenting assembly is situated on one side of the sleeve and includes a filmstrip. Opaque portions of the filmstrip have a desired color to provide a portion of an image and a translucent portion has the remaining portion of the image that is caused to appear and disappear. A dark background is situated behind the translucent portion of the filmstrip and a light colored shield is positioned behind the filmstrip, between the filmstrip and the dark background. The shield has a handle for moving the shield to, and from, a position behind the portion of the image defined by the translucent portion of the filmstrip, thereby to cause it to appear when the shield is moved therebehind.
U.S. Pat. No. 3,414,364—issued to Bert on Dec. 3, 1968 in U.S. class 431 and subclass 143—teaches a pyrophoric cigarette lighter having a disposable fuel container which itself constitutes the main body of the lighter, complemental securing apparatus forming part of the container and cooperating with corresponding complemental securing apparatus carried by a separate igniting mechanism and a separate pressure reducer and burner unit for operatively and detachably affixing the unit and the mechanism to the disposable container. Numerous gas lighters having a disposable refill cartridge allow the user to change not only the cartridge or container, but also one of the components of the lighter. These components, however, form complex assemblies and consequently expensive units. Generally, the pressure reducer and burner unit is either an integral part of the igniting mechanism or is permanently attached to the disposable container, while the igniting mechanism forms a permanent unit with the body of the gas lighter and with the flint-carrying tube and the like.
U.S. Pat. No. 5,460,520—issued to Lin on Oct. 24, 1995 in U.S. class 431 and subclass 255—teaches a gas torch including a container that holds a disposable gas lighter, and a casing detachably connected to the container, at a top thereof to hold an electric ignition device. The casing has a horizontal partition wall to hold a gas flow guide and a flame nozzle. A trigger is turned about a pivot inside the casing and is controlled to depress the gas lever of the disposable gas lighter and the control lever of the electronic ignition device causing a flame produced at the flame nozzle.
U.S. Pat. No. 5,531,591—issued to Yamazaki on Jul. 2, 1996 in U.S. class 431 and subclass 153—teaches a safety device for use in a gas lighter. An actuating member provided on top of a lighter body is supported in a pivotal fashion by a leg downwardly extending therefrom. The leg is also provided with a lock member. A circular-arc-shaped guide groove and a recessed groove at the center-side end of the guide groove are formed along the upper end of one of the tank side surfaces. The lock member has a base portion that travels along a regulation groove in a restricted manner, a stopper that is connected to an upper part of the base portion and is engageable with the recessed groove, a finger grip that permits a lock release operation and causes the stopper fitted into the recessed groove to be engaged with the guide groove, and a spring member for urging the base portion toward the center of the lighter body and holding the lock member in a locked position and an unlocked position. The elements of the lock member are formed into one assembly. Fitting of the stopper into the recessed groove deters the pivotal movement of the actuating member. Disengagement of the stopper from the recessed groove permits pivotal movement of the actuating member, and the lock member is displaced to a lockable position upon coming into contact with the end face of the guide groove. The spring member is in a coiled shape, but may be formed into a U-shaped, V-shaped, or bow-shaped pattern.
U.S. Pat. No. 5,740,905—issued to Kilfoy on Apr. 21, 1998 in U.S. class 206 and subclass 87—teaches a key ring attachable lighter holding shell with flexible holding flaps is a shell-shaped holder into which a reusable lighter or a disposable lighter may be inserted and held securely, yet can also be taken out and replaced again, and it may be attached to a key ring or key chain in order to help prevent a person from losing a lighter as long as the keys are not lost.
U.S. Pat. No. 6,257,872—issued to Williams on Jul. 10, 2001 in U.S. class 431 and subclass 253—teaches a decorative apparatus for removable attachment to a cigarette lighter. The body of which tapers upwardly and inwardly from its base to the top thereof. The apparatus includes a rigid band. The interior of which is smaller than the cross-sectional area of the lighter base, but larger than the cross-sectional area of the lighter top. One or more distinctive members may be affixed to the band for enhancing appearance and identification.
U.S. Pat. No. 6,431,853—issued to Sher on Aug. 13, 2002 in U.S. class 431 and subclass 153—teaches a cigarette lighter including a housing. An ignition apparatus is provided for the lighter. The ignition apparatus includes a member manually movable with respect to the housing. A lock between the manually moveable member and the housing, and release apparatus are manually operable to release the lock to allow the manually moveable member to move relative to the housing to allow or cause ignition of the lighter. The release apparatus requires manual movement to release the lock in a direction different to the direction of movement of the manually moveable member to allow or cause ignition.
U.S. Pat. No. 6,443,727—issued to Huang on Sep. 3, 2002 in U.S. class 431 and subclass 132—teaches a safety lighter that is locked in a non-operable condition with a safety latch operable with a rotatable gear device. The rotatable gear is located in a top surface of the lighter actuator and is coupled to a rack that moves linearly when the gear is rotated. The rack is extended into, or withdrawn from, the lighter housing to prevent or permit actuation of the lighter mechanism, respectfully. A lower portion of the rack has a sloped profile to permit the rack to be pushed upward by the lighter housing when the actuation device is returned to a normal locked position. In the normal locked position, the rack is driven into the lighter housing by a spring located in the actuator. The actuator mechanism is unlocked by rotating the gear in a direction opposite to that of the rotational direction for operating the actuator. The location of the gear on the top surface of the actuator permits the actuator to be unlocked and operated.
U.S. Pat. No. 6,478,575—issued to Sher on Nov. 12, 2002 in U.S. class 43 land subclass 153—teaches a lighter that has a housing, a gas reservoir in the housing, and an ignition apparatus. The ignition apparatus includes a first manually moveable member and a second independently operable and manually moveable member so that when the first member is operated gas is supplied from the gas reservoir and when the second member is operated the ignition apparatus operates, so that both the first manually moveable member and the second manually moveable member must be operated to cause the lighter to ignite. The two manually moveable members may include a cap to the housing and a button moveable in a channel in the cap.
U.S. Pat. No. 6,726,470—issued to Meister on Apr. 27, 2004 in U.S. class 431 and subclass 154—teaches a windproof lighter having an inside unit and an exterior case. The inside unit has an interior chamber, a wick, a flint, a flint position apparatus positioned in the interior chamber, a flint wheel, and a chimney. The lighter has a disposable fuel cell containing lighter fuel. The fuel cell is designed to fit within the interior chamber and to not interfere with the flint position apparatus. When the container is to be used in a windproof lighter, it has an opening that receives the wick. The wick extends into the interior chamber and has a component that is larger than the opening so that when the container is properly positioned within the interior chamber, the component secures the container in position and prevents accidental spillage of the lighter fuel.
U.S. Pat. No. 6,733,277—issued to Huang on May 11, 2004 in U.S. class 431 and subclass 153—teaches a locking lever for a lighter actuation mechanism that prevents the actuator from operating when in a locked position. Operation of the lever causes a portion of the lever to be withdrawn from a housing portion of the lighter and permits the actuator to be moved and operated. The lever mechanism is spring-loaded so that the end of the lever normally extends into the lighter housing in a locked position. A top portion of the lever is flattened and curved to prevent intuitive operation while permitting easy disengaging of the locking mechanism. An end portion of the locking lever has a sloped profile to move the lever in an upward direction when the actuator device is returned to a normal position, after operating the lighter. When the lighter actuator returns to the normal position, the spring-loaded lever again extends into the housing of the lighter to prevent accidental operation. The locking lever is accessible through a top surface of the lighter actuator to permit the lighter to be unlocked and actuated with a simple motion.
U.S. Pat. No. 6,939,128—issued to Suzuki et al. on Sep. 6, 2005 in U.S. class 431 and subclass 130—teaches an ignition operation mechanism for slide type lighters that is capable of preventing accidental ignition or ignition due to erroneous use or the like while maintaining good operability. Pivots for an operating cap are made substantially circular in cross section and so sized as to form a vertically movable clearance as they are locked to a support section in the lighter main body. The pivots for the operating cap are normally urged to be positioned in the upper region of the interior of a support section by the spring force of a return spring for a piezoelectric mechanism. The operating cap is slid until a lever member, strikes the lighter main body, and no longer moves in the slide direction, from which state, the operating cap is pressed downward, whereby the pivots move downward within the support section, whereupon pressing levers reach the operation stroke that overcomes the piezoelectric mechanism producing a discharge voltage to enable ignition.
United States Patent Application Publication Number 2008/0044784—published to Park on Feb. 21, 2008 in U.S. class 431 and subclass 344—teaches two basic components, a housing and a fuel cartridge. The housing may include multiple pieces. The fuel cartridge is easy to remove from the housing without the use of any tools. Thus, an empty fuel cartridge 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. A worn or damaged housing may be removed from the lighter by the user and replaced with a new housing. 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, ribs, and/or tensioning springs to tighten a fit of the housing and prevent spontaneous separation. The surface features may also protect the appearance of the housing.
U.S. Pat. No. 7,815,432—issued to Smith on Oct. 19, 2010 in U.S. class 431 and subclass 143—teaches cigarette lighter having a removable fuel cartridge with a reservoir for holding flammable liquid fuel, a valve for controlling the flow of fuel into and from the reservoir, an ignition actuator for causing ignition of the fuel, a nozzle for causing the ignited fuel to form a lighting flame, and a valve actuator that cooperates with the ignition actuator to open the valve as the ignition actuator is actuated. The reservoir has a transparent portion that is aligned with a window in the lighter housing to allow external observation of the fuel level in the reservoir. The transparent portion includes indicia for gauging the amount of fuel. The indicia is structurally contoured to provide an apparatus for engaging the reservoir to remove the fuel cartridge from the lighter.
Chinese Patent Number CN 201718464 U—issued to Guo on Jan. 26, 2011 in International class A24F15 and subclass 18—teaches a cigarette case with a disposable lighter, which includes a cigarette case body. A cavity for containing the disposable lighter is arranged on one side of the case body. Further included is a lighter cover arranged outside the cavity body. The lighter cover is in a close sliding fit with the case body. The disposable lighter requires no gas charging.
United States Patent Application Publication Number 2016/0052700—published to Hearn et al. on Feb. 25, 2016—teaches a pressurized refill canister containing a composition including a propellant. The canister has an outlet valve having a stem biased to a closed position by a first resilient member. The stem has a maximum outer diameter of greater than 3 mm. At the outlet end of the stem, at least part of the wall of the stem extends inwardly from the outside diameter for at least 50% of the radius.
