TECHNICAL FIELD

The present disclosure relates to the field of lighters, more specifically to a lighter coupleable to geometrically different gas and/or fuel reservoir devices.

BACKGROUND

Lighters used for igniting purposes like igniting tobacco, cigars and/or cigarettes have been developed over the past years. These lighters have a fuel reservoir and either a rotary friction element or a piezoelectric ignition device to generate a spark at a nozzle which emits the fuel delivered by the fuel reservoir. Lighters are commercially available in different forms and sizes, for example as a small pocket lighter such as the BIC Maxi J26. Lighters have also evolved from the small pocket lighters to several forms of extended lighters that are more useful for general purposes, for example lighting candles, barbecue grills, fireplaces and/or campfires such as the BIC MegaLighter U 160. Earlier attempts at such designs relied simply on extended actuating handles to house a typical lighter at the end. However, gas and/or fuel sources of a lighter can also be in the form of gas and/or fuel reservoirs permanently installed in the lighter. There are lighters that are non-refillable and are disposed of when the gas and/or fuel reservoir is empty. In such lighters, a non-commercially available fuel and/or gas reservoir, e.g. the BIC J6S3 GR, can be built into as a sub-assembly by the manufacturer.

Nowadays, however, lighters are in great demand which are refillable, for example for financial and environmental reasons. Such lighters can be refilled, for example, with a separate gas lighter refill, often sold as a can having an adapter to refill the gas and/or fuel reservoir of the lighter. However, it is desirable that gas and/or fuel refill operations are easy to manage, safe and inexpensive. Furthermore, it would be desirable to provide a lighter without a permanently attached gas and/or fuel reservoir, but which is able to couple with an interchangeable and commercially available lighter and/or with an interchangeable, non-commercially available gas and/or fuel reservoir for supplying gas and/or fuel to the lighter. More specifically, with such a lighter a user could safely provide gas and/or fuel to the lighter without discarding any usable parts, as compared to a common non-refillable lighter. Thus, a pocket lighter (e.g., BIC Maxi J26) can not only be used independently as a lighter, but also as a gas and/or fuel source. However, since commercially available lighters (e.g., BIC Maxi J26) and non-commercially available gas and/or fuel reservoirs (e.g., BIC J6S3 GR) differ in its geometrical and structural dimensions, it becomes difficult to selectively couple both variations to a lighter.

The object of the present disclosure is to provide an easy, safe and inexpensive gas and/or fuel refill and/or supply for a lighter. More specifically, the object of the present disclosure is to provide a lighter which can be coupled to geometrically different gas and/or fuel reservoirs devices.

SUMMARY

The present disclosure relates to a lighter according to claim 1. The dependent claims depict embodiments of the present disclosure.

According to a first aspect of the present disclosure, a lighter comprises a housing having a nozzle. The housing is adapted to receive a gas and/or fuel reservoir device. Furthermore, the lighter comprises a connecting device which is configured to couple the gas and/or fuel reservoir device to the nozzle. The connecting device is adjustable along a longitudinal axis of the lighter such that the lighter can be coupled to different gas and/or fuel reservoir devices having different geometrical and/or structural dimensions. Since the connecting device is adjustable, the lighter can be coupled to variations of gas and/or fuel reservoir devices which might have different geometrical and structural dimensions. As an example, the lighter according to the present disclosure can be selectively coupled to a commercially available pocket lighter or to a non-commercially available gas and/or fuel reservoir. Thus, a lighter can be provided with an easy, safe and inexpensive refill and/or supply of gas and/or fuel. Furthermore, an eco-friendly lighter can be provided because less components have to be disposed of as compared to a non-refillable lighter. In this document, a lighter can be defined as being a portable combustion product and/or a flame producing assembly. Such products and/or assemblies are generally designed to produce a flame out of the combustion of a flammable material, when ignited by an ignition device, that can be integrated to the lighter. The flammable material can be stored within the portable combustion product and/or flame producing assembly, for example in a container comprised within or at the housing of the lighter. The flammable material used in lighters can be liquefied gas, for example liquefied hydrocarbon of the n-butane, isobutane, propane type or a mixture of these gases commonly named liquefied petroleum gas (LPG). The portable combustion products and/or flame producing assemblies are widely used for igniting a variety of combustible materials and items such as cigarettes, candles, flammable gas (e.g., in gas stoves), fireplaces, and many others. Portable combustion products and/or flame producing assemblies and/or lighters can be commercially available in different forms and sizes.

The lighter can comprise a longitudinal axis, wherein the connecting device can be adjustable along the longitudinal axis. This means that a size or dimension of the connecting device along the longitudinal axis is variable. More specifically, the connecting device may be adjustable by at least 0.5 mm, in particular by at least 0.7 mm, along the longitudinal axis.

Furthermore, the connecting device can be adjustable between a fully extended position and a fully retracted position. The distance between the fully extended position and the fully retracted position may be in the range of 0.5 to 15 mm, in particular in the range of 0.7 to 10 mm, more specifically in the range of 0.8 to 8 mm.

The connecting device can comprise a biasing element, more specifically a compression spring, wherein the biasing element can bias the connecting device in the direction of the longitudinal axis.

In the fully extended position as described above, the biasing element may have a biasing force of at least 40%, more specifically of at least 50%, in particular of at least 60%, compared to the biasing force in the fully retracted position.

The connecting device can be adjustable transverse to the longitudinal axis, wherein the connecting device may be adjustable by an angle a of at least 5°, more specifically by at least 7°, in particular by at least 10°, measured between the longitudinal axis of the lighter and a longitudinal axis of the connecting device.

The connecting device may comprise a cylindrical connecting body having a length and a diameter. The connecting body may have an outer circumferential surface, a first end face and a second end face. Furthermore, the connecting body may comprise an opening, defining an inner circumferential surface.

The connecting body can comprise a chamfer arranged between first end face and outer circumferential surface. The chamfer may extend at least partially over the circumference of the connecting body. The chamfer should be understood as a slope cut arranged at a right-angled portion or any other place where two surfaces meet at a sharp angle. In particular the chamfer is a slope cut or portion arranged between the first end face and the outer circumferential surface.

The connecting body can comprise a recess extending at least partially over the outer circumferential surface. The recess may extend at least partially over the length of the connecting body.

The recess and the chamfer or slope cut as described above may be substantially aligned to each other on the outer circumferential surface with respect to the longitudinal axis of the connecting device. The recess and the chamfer may be oriented toward a center of the lighter.

Starting from the first end face of the connecting body along the longitudinal axis, the connecting body may comprise the chamfer, followed by a section of the diameter as mentioned above, followed by the recess.

The housing may comprise a support element configured to receive and support the connecting device. The connecting device may be movably received by the support element.

According to a second aspect of the present disclosure, a lighter is provided according to the first aspect of the present disclosure, but which can further comprise a gas and/or fuel reservoir device coupled to the lighter. The gas and/or fuel reservoir device may be configured to be replaceably coupled to the lighter. The gas and/or fuel reservoir device may comprise a fluid reservoir and a valve assembly for selectively dispensing fuel and/or gas, more specifically wherein the connecting device may be configured to be coupled to the valve assembly in a fluid-tight manner.

For all aspects and embodiments as described above, the gas and/or fuel reservoir device may be configured to be independently used as a lighter.

Embodiments of the lighter according to the present disclosure will be described in reference to the drawings as follows.

Fig. 1 is a schematic view of a lighter 1 according to the present disclosure. The lighter 1 comprises a housing 10 which has a nozzle 40. The housing 10 is adapted to receive a gas and/or fuel reservoir device 20. Furthermore, the lighter 1 comprises a connecting device 30, which is configured to couple the gas and/or fuel reservoir device 20 to the nozzle 40. The connecting device 30 is adjustable, which is described in more detail below. Since the connecting device is adjustable, the lighter can be coupled to variations of gas and/or fuel reservoir devices which might have different geometrical and structural dimensions. As an example, the lighter 1 according to the present disclosure can be selectively coupled to a commercially available pocket lighter or to a non-commercially available gas and/or fuel reservoir. Thus, a lighter can be provided with an easy, safe and inexpensive refill and/or supply of gas and/or fuel. Furthermore, an eco-friendly lighter can be provided because less components have to be disposed of as compared to a non-refillable lighter.

As shown in Fig. 1, the lighter 1 comprises a longitudinal axis LI, which extends in a longitudinal direction of the lighter 1. Thereby, the longitudinal axis LI can extend through a center of the lighter 1, more specifically through a geometrical center of the housing 10 of the lighter 1. The housing 10 comprises a housing recess 12 which is configured to receive and support the gas and/or fuel reservoir device 20. The housing recess 12 may extend in a longitudinal direction of the housing 10, beginning from one end face of the housing 10, which may be opposite the nozzle 40. In the embodiment shown in Fig. 1, the housing recess 12 extends aligned to the longitudinal axis LI. More specifically, the longitudinal axis LI extends through the geometrical center of the housing recess 12.

The lighter 1 may further comprise a lid, however not shown in Fig. 1, which may be designed to be coupled to the housing 10. More specifically, the lid may be configured to cover the housing recess 12. In embodiments, the lid may be coupled to the housing 10 by a positively locking connection, more specifically by a snap-fit connection. The lid may be a separate component and the housing may comprise a flange, wherein the lid can be pushed over the housing flange, more specifically along the longitudinal axis LI . Additionally or alternatively, the lid can be connected to the housing 10 via a hinge. Thereby, at least on edge of the lid may be connected by a pin to the housing 10, more specifically to an edge of the housing flange. Thus, the lid can be pivoted towards to the housing 10 in order to cover the housing recess. Furthermore, the lid may comprise a tensioning element which may be configured to apply a preload in the direction of the longitudinal axis LI.

Figs. 3 and 5A to 5C are schematic views of the adjustable connecting device 30. As shown in Fig. 5B, a coordinate system can be defined for the connecting device 30. The coordinate system comprises a longitudinal direction x of the connecting device 30, a radial direction r of the connecting device 30 which is perpendicular to the longitudinal direction x, and a perpendicular direction p which is perpendicular to the longitudinal direction x and the radial direction r.

As shown in Figs. 3 and 5B, the connecting device 30 comprises a connecting body 34, wherein the connecting body 34 may be cylindrical. The connecting device 30 comprises a longitudinal axis L2 which extends through the center of the connecting device 30 in the longitudinal direction x of the connecting device 30, more specifically in the longitudinal direction x of the connecting body 34. The connecting body 34 is defined by a length 1 and a diameter d. Furthermore, the connecting body 34 has an outer circumferential surface 341, a first end face 342 and a second end face 343. As shown in Fig. 5B, the connecting body 34 comprises an opening 344, which defines an inner circumferential surface 345. The opening 344 may extend through the connecting device, more specifically the connecting body 34, from the first end face 342 to the second end face 343. The connecting body 34 comprises a coupling member 38 which can be arranged at the second end face 343. The coupling member may be rigidly connected to the connecting body 34. The coupling member 38 may be configured to couple the connecting device 30 to the nozzle 40. The coupling member 38 may comprise a coupling opening which may be fluidly coupled to the opening 344 of the connecting device 30.

As shown in Figs. 3 and 5B, the connecting body 34 comprises a chamfer 346 or slope cut. The chamfer 346 is arranged between the first end face 342 and the outer circumferential surface 341. The chamfer 346 may extend at least partially over a circumference of the connecting body 34. The circumference of the connecting body 34 may be defined on the outer circumferential surface 341 with respect to the longitudinal axis L2. The chamfer may extend from the first end face 342 at a position which is less than half the diameter d in an oblique direction toward the outer circumferential surface 341 of half the diameter d. The oblique direction may be defined by the radial direction r with respect to the longitudinal axis L2 and the longitudinal direction x with respect to the longitudinal axis L2. In a plane defined by the radial direction r and the longitudinal direction x, the chamfer 346 may comprise a linear shape and/or a concave shape and/or a convex shape and/or a wave-shape comprising a concave portion and a convex portion. Additionally or alternatively, the chamfer 346 may comprise rounded edges.

In embodiments, the connecting body 34 comprises a bevel 347 arranged between the first end face 342 and the inner circumferential surface 345. The bevel may extend at least partially over the circumference of the inner circumferential surface 345. In embodiments, the bevel extends over the circumference of the inner circumferential surface 345 of the connecting body 34.

As shown in Figs. 3, 5B and 5C, the connecting body 34 comprises a recess 348 which extends at least partially over the outer circumferential surface 341. More specifically, the recess 348 extends at least partially over the length 1 of the connecting body 34. Referring to Fig. 5C, the recess 348 may have a planar shape on the outer circumferential surface 341, which may form a plane that is substantially parallel to a plane x-p defined by the longitudinal direction x and the perpendicular direction p.

In embodiments, the connecting body 34 may only comprise the chamfer 346 or the recess 348. In case the connecting body 34 comprises both the recess 348 and the chamfer 346, the recess 348 and the chamfer may be substantially aligned to each other on the outer circumferential surface 341, more specifically on a circumferential position of the connecting body 34, with respect to the longitudinal axis L2. Referring to Fig. 2, the longitudinal axis LI of the lighter 1 and the longitudinal axis L2 of the connecting device 30 may lie in the same plane with respect to the perpendicular direction p. Thus, the recess 348 and the chamfer 346 may be oriented toward the center of the lighter 1, more specifically toward the geometric center of the lighter 1. In other words, the recess 348 and the chamfer 346 may be oriented toward the longitudinal axis LI of lighter 1. As shown in Figs. 3 and 5B, when starting from the first end face 342 along the longitudinal axis L2, more specifically in the longitudinal direction x, the connecting body 34 comprises the chamfer 346, followed by a section of diameter d, followed by the recess 348. However, in embodiments, the recess 348 may extend from the first end face 342 at least partially along the connecting body 34 toward the second end face 343. Thus, starting from the first end face 342, the connecting body 34 may comprise the chamfer 346, followed by the recess 348. In embodiments, the chamfer 346 may not be provided at all. Thus, starting from the first end face 342, the connecting body may comprise the recess 348 extending at least partially along the connecting body 34 toward to second end face 343.

As shown in Figs. 3 and 5B, the connecting body 34 comprises a first portion 350 proximate the first end face 342 having diameter d and a length 11. Furthermore, the connecting body 34 comprises a second portion 351 proximate the second end face 343 having a diameter dl and a length 12. The diameter dl of the second portion 351 may be larger than the diameter d of the first portion 350. The second portion 351 may be rigidly connected to the first portion 350. In embodiments, the connecting body 34 further comprises a third portion 352 arranged between the first portion 350 and the second portion 351, wherein the third portion 352 has a diameter d2 and a length 13. In this case, the first portion 350 may be rigidly connected to the third portion 352 and the third portion 352 may be rigidly connected to the second portion 351. The diameter dl of the second portion 351 may be larger than the diameter d of the first portion 350 and/or the diameter d2 of the third portion 352. More specifically, the diameter d2 of the third portion 352 may be smaller than the diameter d of the first portion 350 and/or the diameter dl of the second portion 351. In embodiments, the length 12 of the second portion 351 may be less than the length 11 of the first portion 350 and/or the length 13 of the third portion 352. The length 11 of the first portion 350 and/or the length 13 of the third portion 352 may be at least 2 times, in examples at least 4 times, larger than the length 12 of the second portion 351. At least a portion of the connecting body 34 may comprise a square-shaped cross-section, more specifically a square-shaped cross-section with rounded edges. As shown in Fig. 5 A, the third portion 352 comprises a square-shaped cross-section with rounded edges.

The opening 344 as described above may have a first opening portion proximate the first end face 342, more specifically in the first portion 350, having a first opening diameter, and a second opening portion proximate the second end face 343, more specifically in the second and third portion 351, 352, having a second opening diameter. The first opening portion and the second opening portion may be fluidly coupled to each other. The first opening diameter may be larger than the second opening diameter.

As shown in Figs 5B and 5C, the connecting device 30 further comprises a seal member 35, more specifically a seal bushing. The seal member 35 may be configured to couple to the gas and/or fuel reservoir device 20. The seal member 35 may be arranged in the connecting body 34, more specifically in the opening 344 of the connecting body 34 proximate the first end face 342, in particular in the first opening portion.

As shown in Figs. 3 and 5B, the connecting body 34 comprises a groove 36 on the outer circumferential surface 341. The groove 36 may extend at least partially over the circumference of the connecting body 34. In embodiments, the groove 36 may extend over the whole circumference of the connecting body 34. The groove may be formed between first portion 350 and third portion 352. As can be seen in Figs. 4A to 4C, the connecting device 30 may comprise a retaining ring 37, which can be inserted into the groove 36.

As shown in Figs. 1, 2 and 4A to 4C, the connecting device 30 is arranged in the housing 10. The housing 10 comprises a support element 11 that is configured to receive and support the connecting device 30. The connecting device 30 may be movably received by the housing 10, more specifically by the support element 11. In embodiments, the support element 11 may support and receive the third portion 352 of the connecting body 34.

Referring to Figs. 1, 2 and 4A to 4C, the connecting device 30 is adjustable substantially along the longitudinal axis LI. In embodiments, the connecting device 30 is adjustable along the longitudinal axis LI. More specifically, the connecting device 30 can be adjustable by at least 0.5 mm, more specifically by at least 0.7 mm, along the longitudinal axis LI. It should be understood that an adjustment of the connecting device 30 does not mean that the connecting device 30 is actively actuated by another component, e.g. actively actuated by an actuator which may adjust the position of the connecting device 30 due to any input, e.g. like a force and/or a control signal. Rather, it means that the connecting device 30 is configured to move when another component transmits a force to the connecting device 30 which will be described more detailed below. However, it should be understood that active actuation of the connecting device 30 may not be excluded in the present disclosure.

Figs. 4A to 4C are schematic views of the adjustable connecting device 30. The connecting device 30 is adjustable between a fully extended position Pl and a fully retracted position. The fully extended position Pl of the connecting device is shown, for example, in Fig. 4A. A retracted position P2 is present, when, starting from the fully extended position Pl, the connecting device 30 is adjusted and/or moved along the longitudinal axis LI relative to the housing 10, more specifically relative to the support element 11 (see, e.g., Fig. 4B or 8A). The fully retracted position is reached, when the connecting device 30 is adjusted along the longitudinal axis LI relative to the support element 11 as far as possible depending on geometric conditions, more specifically stops, that are described in detail below. In embodiments, the distance between the fully extended position Pl and the fully retracted position may be in the range of 0.5 to 15 mm, more specifically in the range of 0.7 to 10 mm, in particular in the range of 0.8 to 8 mm.

As shown in Figs. 1, 2 and 4A to 4C, the connecting device 30 comprises a biasing element 31, wherein the biasing element 31 biases the connecting device 30 in the direction of the longitudinal axis LI of the lighter 1, more specifically along the longitudinal axis L2 opposite the longitudinal direction x. The biasing element 31 may be a compression spring, more specifically a coil spring. When the connecting device 30 is not adjusted, as shown in Fig. 4A, the biasing element 31 biases the connecting device 30 to maintain in the fully extended position Pl. In the fully extended position Pl, the longitudinal axis L2 of the connecting device 30 may be substantially parallel to the longitudinal axis LI of the lighter 1. In the fully extended position Pl, the biasing element 31 may have a biasing force of at least 40%, more specifically of at least 50%, in particular of at least 60%, compared to the biasing force in the fully retracted position.

As shown in Fig. 4C, the connecting device 30 is not only adjustable along the longitudinal axis LI, but is also adjustable transverse to the longitudinal axis LI of the lighter 1. More specifically, the connecting device 30 may be pivotable. “Transverse” refers to a direction which is perpendicular to the longitudinal axis LI in a plane defined by longitudinal axis LI and transverse direction when the lighter 1 is viewed from a side view, e.g. as shown in Figs. 1 and 2. More specifically, the connecting device 30 may be pivotable about an imaginary pivot axis PA which is perpendicular to the plane defined by longitudinal axis LI and the transverse direction. The connecting device 30 may be pivoted substantially about the structure of the support element 11 that supports the connecting device 30, more specifically substantially about the imaginary pivot axis PA of the support element 11, shown in Fig. 4C. However, it should be noted that the imaginary pivot axis PA may change its position depending on forces acting on the connecting device 30 and respective force application points FAP. Such a force application point FAP is shown in Fig. 4C. The connecting device is adjustable in the transverse direction, since the gas and/or fuel reservoir device 20, which may be coupled to the lighter, can have structural components wherein a direct access of the connecting device 30 to couple to the gas and/or fuel reservoir device 20 may not be possible. Since the connecting device 30 is adjustable along the longitudinal axis LI and/or transverse to the longitudinal axis LI, the connecting device 30 may compensate for geometrical differences and/or may move around any structural components of the gas and/or fuel reservoir device 20 to couple to the latter.

Referring to Fig. 4C, the connecting device 30 may be adjustable by an angle a of at least 5°, more specifically by at least 7°, in particular by at least 10°, measured between the longitudinal axis LI of the lighter 1 and a longitudinal axis L2 of the connecting device 30. It is to be noted that in Fig. 4C, the longitudinal axis LI has been moved parallel from the center of the lighter 1 as described above toward the connecting device 30, in order to simplify a visualization of the angle a. Angle a may be present when the connecting device 30 is adjusted in the transverse direction, in other words when the connecting device 30 is pivoted.

In embodiments, wherein, when starting from the first end face 342 of the connecting body 34 the chamfer 346 is provided followed by the recess 348, or only the recess 348 is provided, it may be sufficient that the connecting device 30 is only adjusted along the longitudinal axis LI, but not in the transverse direction.

As shown in Figs. 2 and 4A to 4C, the connecting device 30 comprises a first stop 33 and the housing 10 comprises a second stop 32. The biasing element 31 is arranged between the first stop 33 and the second stop 32. The biasing element 31 may surround the outer circumferential surface 341 of the connecting body 34. More specifically, the biasing element 31 may surround the third portion 352. In embodiments, the first stop 33 is formed by the retaining ring 37, when the retaining ring 37 is inserted into the groove 36. However, in an embodiment, instead of providing the groove 36 and the retaining ring 37, the first stop 33 may be formed by a side wall of the first portion 350, which may be provided when the diameter d of the first portion is larger than the diameter d2 of the third portion 352. Alternatively, the first stop 33 may be formed a fourth portion, which may be arranged between third portion 352 and first portion 350, and which may have a diameter that is larger than the diameter d2 of the third portion 352. The fourth portion may be rigidly connected to the first portion 350 and the third portion 352. As shown in Figs. 2 and 4A to 4C, the second stop 32 is formed by the support element 11, more specifically by at least a portion of a side wall of the support element 11 facing the first stop 33. The connecting device 30 further comprises a third stop 331, more specifically wherein the third stop 331 is formed by the second portion 351.

As shown in Fig. 4A, in the fully extended position Pl, the third stop 331 contacts the second stop 32. More specifically, the third stop 331 may contact at least a portion of a side wall of the support element 11 facing the third stop 331. In other words, in the fully extended position Pl, the second portion 351 (or third stop 331) contacts the support element 11 on a first side wall of the support element 11. In this embodiment, the biasing element 31 is arranged between a second side wall of the support element 11, opposite the first side wall, and the first stop 33. The first side wall of the support element 11 may face toward the nozzle 40 of the lighter 1 and the second side wall of the support element 11 may face toward the housing recess 12 of the lighter 1.

As shown in Fig. 4B, in a retracted position P2 which is between the fully extended position Pl and the fully retracted position, and/or in the fully retracted position of the connecting device 30, a distance dretract can be defined between the second stop 32 and the third stop 331. The distance dretract may refer to the respective distances in mm as described above.

Fig. 4C shows an adjusted, retracted position P3 of the connecting device 30 wherein the connecting device 30 is adjusted along the longitudinal axis LI and transverse to the longitudinal axis LI, thus forming the angle a. Such a retracted position P3 occurs when a force is applied on the connecting device 30, more specifically wherein the force can be applied on the chamfer 346 shown by force application point FAP. Thereby, the force is obliquely applied on the connecting device 30, having not only a force component in the direction of the longitudinal axis LI, but also in the transverse direction with respect to the longitudinal axis LI. The angle a as described above is formed due to the application of the oblique force. Since the biasing element 31 can be a compression spring, more specifically a coil spring, the biasing force of the biasing element 31 may increase on a side of the connecting device 30, to which the connecting device 30 is adjusted and/or pivoted. When the force is released from the connecting device 30, the increased biasing force may push the connecting device 30 back to the fully extended position Pl, wherein the angle a may be about 0° and/or wherein the distance dretract may be about 0.0 mm. As described above, the support element 11 is configured to support and receive the connecting device 30, more specifically wherein the connecting device 30 can be adjustably and/or movably received by the support element 11. Referring to Figs. 3 and 4A to 4C, the support element 11 and/or the connecting device 30 may be adapted to prevent rotation of the connecting device 30 about its longitudinal axis L2 when received by the support element 11. In a first embodiment, rotation of the connecting device 30 may be prevented by the squareshaped cross-section of the connecting body 34, more specifically the third portion 352, and an associated shape of the support element 11 that allows adjustment of the connecting device 30 but prevents rotation about longitudinal axis L2. Additionally or alternatively, the connecting body 34 may comprise an anti-rotation element 39 on the outer circumferential surface 341, wherein the anti -rotation element 39 may protrude in a radial direction of the connecting body 34 from the outer circumferential surface 341.

Referring to Figs. 1 and 2, the lighter 1 comprises an igniter assembly 50 operatively connected to the housing 10 for generating a spark at the nozzle 40, more specifically at the nozzle outlet 41. The igniter assembly 50 comprises a piezoelectric mechanism 51, which is adapted to provide electrical voltage due to an application of force on solids. The housing 10 may comprise an electrically conductive component which may be electrically coupled to the piezoelectric mechanism 51. The electrically conductive component may be arranged between the nozzle 40, more specifically the nozzle outlet 41, and the piezoelectric mechanism 51 to form an electrode. Referring to Fig. 7 the nozzle 40 may include at least a protruding portion 401 with electrically conductive material which is electrically coupled to the piezoelectric mechanism 51. Thus, when the piezoelectric mechanism 51 is actuated, a spark is formed between the nozzle 40 comprising an electrically conductive material and the electrically conductive component, more specifically wherein the spark is formed at the nozzle outlet 41. In embodiments, the electrically conductive component may include a tab extending toward the nozzle 40, more specifically toward the nozzle outlet 41, wherein the spark may be formed between the tab and the nozzle 40. The lighter 1 may comprise an electrically insulating component disposed around at least a portion of the nozzle 40 for preventing undesired sparks between the nozzle 40 and the electrically conductive component.

As shown in Figs. 1 and 2, the lighter 1 comprises an actuating assembly 60 operatively coupled to the housing 10 and configured to operatively activate the igniter assembly 50. The actuating assembly 60 comprises a linkage arm 61 which may be operatively coupled to the igniter assembly 50 for activating the igniter assembly 50. The linkage arm 61 may, when actuated, compress the piezoelectric mechanism 51 which in turn will generate a spark at the nozzle 40, more specifically at the nozzle outlet 41. In embodiments, a pin 13 is rigidly connected to the housing 10, wherein the linkage arm 61 may be coupled to the pin 13. More specifically, the linkage arm 61 may be pivotably coupled to the pin 13. The actuating assembly 60 further comprises a trigger member 62 operatively coupled to the linkage arm 61 and to the housing 10. The trigger member 62 may be adapted to be actuated by a user. The igniter assembly 50 may be activated by the linkage arm 61 when a user actuates the trigger member 62. The trigger member 62 may extend from the housing 10 and may be movable from a first, unactuated position to a second, actuated position. Referring to Fig. 2, a biasing member 14 is arranged between housing 10 and actuating assembly 60, more specifically between housing 10 and trigger member 62, which may be configured to urge the trigger member 62 and/or the linkage arm 61 to the first, unactuated position in case the trigger member 62 is not actuated by a user.

In embodiments, however not shown in the figures, the housing 10 may further comprise a locking element operatively coupled to the actuating assembly 60. The locking element may be movable between a first locking element position and a second locking element position. In the first locking element position, the locking element may prevent operative movement of the actuating assembly 60 and in the second locking element position, the locking element may permit operative movement of the actuating assembly 60. The locking element may be provided in order to increase the safety of the lighter, e.g. to make the lighter child resistant. In the first locking element position, a movement of the actuating assembly 60, more specifically of the trigger member 62 may be prevented such that the igniter assembly 50 cannot be actuated. In other words, in the first locking element position, the locking element may prevent operative movement of the trigger member 62 even when a force is applied by a user on the trigger member 62. In embodiments, the locking element may be configured to be automatically moved to the first locking element position when not actuated by a user. The locking element may be provided as a switch operatively coupled to the housing. The switch may be movable from the first locking element position to the second element position. Additionally or alternatively, the safety of the lighter 1 may be increased by an adaption of the force required to activate the lighter 1, e.g. via the biasing element 14 and/or by the actuating assembly 60 shown in Fig. 2. The biasing element may be configured to urge the trigger member 62 to the first, unactuated position. In order to actuate the lighter 1, a user may have to apply a force on the trigger member 62 that is larger than the spring force provided by the biasing element 14 and/or that is large enough to actuate the actuating assembly 60, e.g. for activating the igniter assembly 50 and/or the gas and/or fuel reservoir device 20. In embodiments, the biasing element 14 may be adapted to provide a spring force sufficiently large and/or the actuating assembly 60 may be configured to require an actuation force large enough to provide a child safety lock for the lighter 1, thus increasing safety of the lighter 1.

According to a second aspect of the present disclosure, a lighter 1 comprises the gas and/or fuel reservoir device 20 coupled to the lighter 1, as shown in Figs. 1 and 2. The lighter 1 can be provided with any of the embodiments as described for the first aspect of the present disclosure. The gas and/or fuel reservoir device 20 is configured to be replaceably coupled to the lighter 1. The gas and/or fuel reservoir device 20 is configured to be inserted into the housing 10. More specifically, the gas and/or fuel reservoir device 20 is configured to be inserted into the housing recess 12.

The gas and/or fuel reservoir device 20 is now described in more detail. Figs. 6A and 6C are exploded views of two different embodiments of the gas and/or fuel reservoir device 20, which can be coupled to the lighter 1, respectively. As shown in Figs. 6A and 6C, the gas and/or fuel reservoir device 20 comprises a fluid reservoir 21 and a valve assembly 22 for selectively dispensing gas and/or fuel. The fluid reservoir 21 can be filled with gas and/or fuel and may be refilled when empty. In an embodiment, the gas and/or fuel in the fluid reservoir 21 can be liquid and can become gaseous when exiting the fluid reservoir 21. The fuel and/or gas may be isobutane blend hydrocarbon comprising a density at 23°C of at least 0.553 g/cm ³ and vapor pressure at 55°C up to 679kPa. The fluid reservoir 21 can be made of plastic, more specifically polyacetal, in particular Delrin. The fluid reservoir 21 comprises a base 212 that is connected to the fluid reservoir 21 on one side of the fluid reservoir. The base 212 may comprise an opening extending through the base 212 such that the fluid reservoir 21 can be filled with fuel and/or gas through the opening. The fluid reservoir 21 may comprise a ball 213 provided in the opening which, together with the structure of the base 212, may act as a non-return valve which prevents fluid from leaking out of the fluid reservoir 21 through the base 212. On a side of the fluid reservoir 21 opposite the base 212, the fluid reservoir comprises at least one protrusion 211, more specifically two protrusions 211, which may be separated from each other and which extend in a longitudinal direction of the fluid reservoir 21.

The valve assembly 22 comprises an adjustable valve 23 and a valve actuator 24, wherein the valve actuator 24 is operatively coupled to the valve 23 for opening and closing the valve 23. The protrusions 211 are configured to pivotally support the valve actuator 24. The adjustable valve 23 comprises a movable valve member 231 and a valve seat 232, which is configured to movably receive the valve member 231. The valve seat 232 is rigidly connected to the fluid reservoir 21. The movable valve member 231 is operatively coupled to the valve actuator 24 for opening and closing the valve 23. Alternatively, the valve assembly 22 may comprise a non- adjustable valve.

The gas and/or fuel reservoir device 20 comprises a spring element 25 coupled to the valve actuator 24, wherein the spring element 25 may urge the valve actuator 24 to an unactuated position wherein the valve 23 is closed. In this case, the valve member 231 is pushed against the valve seat 232, wherein the gas and/or fuel reservoir 20 is prevented from dispensing gas and/or fuel. With respect to Fig. 6B, the valve 23 may further comprise a rubber gasket 233 connected to the valve member 231 such that a fluid-tight connection between valve member 231 and valve seat 232 can be provided when the valve 23 remains unactuated. The valve 23 further comprises a membrane 234 for regulating fluid flow, which may be connected to the valve seat 232, and a disk 235 for sealing the membrane 232 in the valve seat 232. The valve assembly 22 may further comprise a hood 28 coupled to the fluid reservoir 21 and covering at least one or more of the components as described above. Referring to the embodiment of the gas and/or fuel reservoir device 20 shown in Figs. 6C and 6D, the gas and/or fuel reservoir device 20 is configured to be independently used as a lighter, e.g. as a pocket lighter such as the BIC Maxi J26. In the embodiment of the gas and/or fuel reservoir device 20 shown in Figs. 6C and 6D, the gas and/or fuel reservoir device 20 comprises an ignition device 26 for generating a spark at the valve assembly 22, more specifically at the valve 23. The ignition device 26 comprises a spark wheel 261 coupled to the gas and/or fuel reservoir device 20 and a flint 262 coupled to the gas and/or fuel reservoir device 20, wherein the flint 262 is operatively coupled to the spark wheel 261 to generate a spark upon rotation of the spark wheel 261. The valve actuator 24 may be operatively coupled to the ignition device 26. Alternatively, the ignition device 26 may comprise a piezoelectric component which may be configured to generate a spark at the valve 23 upon activation by the valve actuator 24. The gas and/or fuel reservoir device 20 may comprise a spring member 264, that urges the flint 262 toward the spark wheel 261. The ignition device 26 comprises a guard member 263 which may be adapted to prevent rotation of the spark wheel 261 in the absence of a pushing force by a user toward the spark wheel 261. Additionally, the guard member 263 may be adapted to allow rotation of the spark wheel 261 in the presence of a pushing force by a user toward the spark wheel 261. The guard member 263 comprises a nose 265 which protrudes towards the valve 23, more specifically towards the movable valve member 231.

The connecting device 30 is configured to be coupled to the valve assembly 22, more specifically to the adjustable valve 23, in a fluid-tight manner. When coupled, the connecting device 30, more specifically the connecting body 34, receives the valve 23, more specifically the movable valve member 231, in the opening 344 proximate the first end face 342. The fluid- tight connection can be provided by the seal member 35 configured to receive the valve member 231.

The actuating assembly 60 as described above and coupled to the housing 10 is further configured to operatively actuate the gas and/or fuel reservoir device 20 for dispensing the gas and/or fuel, more specifically to operatively actuate the valve actuator 24. Referring to Fig. 2, the linkage arm 61 is configured to be operatively coupled to the igniter assembly 50 for activating the igniter assembly 50 and/or is configured to be operatively coupled to the gas and/or fuel reservoir device 20 for dispensing gas and/or fuel. More specifically, the valve assembly 22, in particular the valve actuator 24, may be configured to be actuated by the linkage arm 61 when a user actuates the trigger member 62. When actuated, the valve member 231 is moved by the valve actuator 24 in the direction of the longitudinal axis LI. The movement of the valve member 231 to open the valve 23 for dispensing gas and/or fuel may be either compensated by a movement of the valve member 231 in the opening 344 of the connecting device 30 relative to the connecting device 30, and/or by a movement of the valve member 231 and the connecting device 30 relative to the housing 10, more specifically relative to the support element 11 due to an adjustment of the connecting device 30.

In embodiments, the second, actuated position of the actuating assembly 60 may comprise a first actuation step and a second actuation step subsequent to the first actuation step. In the first actuation step, the linkage arm 61 may be configured to actuate only the valve assembly 22. In the second actuation step, the linkage arm 61 may be configured to actuate the valve assembly 22 and to activate the igniter assembly 50. These features can ensure that gas and/or fuel is already available at the nozzle outlet 41 when a spark is generated.

In embodiments, as shown in the schematic views of the lighter 1 in Figs. 8A and 8B, the actuating assembly 60 comprises an intermediate pivoting turn rod 63 coupled to the housing 10, more specifically wherein the intermediate pivoting turn rod 63 is pivotally coupled to the housing 10 by a turn rod pin 64. The turn rod 63 is arranged between the linkage arm 61 and the gas and/or fuel reservoir device 20. More specifically, the turn rod 63 is operatively coupled to the linkage arm 61 and the valve actuator 24. The turn rod 63 may comprise a turn rod opening 65 configured to receive and slidingly support a projection of the linkage arm 61, e.g. as shown in Fig. 8B. In the first actuation step, the linkage arm 61 may be configured to actuate the valve assembly 22 via the turn rod 63 in order to anticipate the opening of the valve 23 for a better and stabilized lighting efficiency of the lighter 1.

Referring to Figs. 1 and 2, the gas and/or fuel reservoir device 20 is coupled to the connecting device 30 and is thus fluidly coupled to the nozzle 40 via the connecting device 30. More detailed, when the gas and/or fuel reservoir device 20 is actuated thus dispensing gas and/or fuel, the gas and/or fuel is dispensed from the fluid reservoir 21 through the valve seat 232 and flows into an opening of the valve member 231. The valve 23, more specifically the valve member 231, and the connecting device 30 are fluidly coupled such that the gas and/or fuel can flow via the connecting device 30 and the conduit to the nozzle 40, more specifically to the nozzle outlet 41. Due to the features described above, there may be geometrical differences between the embodiment of the gas and/or fuel reservoir device 20 as shown in Fig. 6A (which will be referred to in the following as a first gas and/or fuel reservoir device) compared to the embodiment of the gas and/or fuel reservoir device 20 as shown in Fig. 6C (which will be referred to in the following as a second gas and/or fuel reservoir device). First and second gas and/or fuel reservoir devices may have a different height, more specifically wherein the height may be measured between the base 212 and the valve 23. The difference in height may be at least 0.3 mm, more specifically at least 0.5 mm, in particular at least 0.7 mm. However, the difference in height between first and second gas and/or fuel reservoir devices can be compensated by the connecting device 30 being adjustable along the longitudinal axis LI, e.g. as shown in Fig. 8A.

Furthermore, the geometric structure of the first gas and/or fuel reservoir device may allow a direct access of the connecting device 30 to couple to the first gas and/or fuel reservoir device. However, since the second gas and/or fuel reservoir device comprises a guard member 263 having a nose 265 protruding towards the valve 23, a direct access of the connecting device 30 to couple to the second gas and/or fuel reservoir device may not be possible. However, since the connecting device 30 is adjustable in a transverse direction (and/or pivotable), the connecting device 30 may get around the nose 265 and couple to the second gas and/or fuel reservoir device.

Referring to Figs. 1 and 2, the coupling of the gas and/or fuel reservoir device 20 to the lighter 1 will now be described in more detail. A user detaches the lid from the housing 10 such that the housing recess 12 is opened to receive and support the gas and/or fuel reservoir device 20. Then a user pushes the gas and/or fuel reservoir device 20 into the housing recess 12 along the longitudinal axis LI and with the valve assembly 22 oriented towards the nozzle, more specifically toward the connecting device 30. The gas and/or fuel reservoir device 20 contacts the connecting device 30 such that the connecting device 30 can be coupled to the valve assembly 22, more specifically to the valve 23, in a fluid-tight manner. During coupling and depending on the geometric structure of the gas and/or fuel reservoir device 20 as described above, the connecting device 30 may be adjusted along the longitudinal axis LI and/or in the transverse direction. If a direct access of the connecting device 30 to the valve 23 with respect to the longitudinal axis LI is possible, the connecting device 30 may only be adjusted along the longitudinal axis LI . If a direct access of the connecting device 30 to the valve 23 with respect to the longitudinal axis LI is not possible, the connecting device 30 may be adjusted in the transverse direction and/or is pivoted to get around the geometric structure. In case the gas and/or fuel reservoir device 20 comprises the nose 265 protruding to the valve 23, the nose 265 may contact the connecting body 34, more specifically the chamfer 346, at force application point FAP as shown in Fig. 4C. The connecting device 30 pivots and the shape of the chamfer 346 assists the connecting body 34 to slide around the nose 265 when the gas and/or fuel reservoir device 20 is pushed towards the connecting device 30. Subsequently, the nose 265 reaches the recess 348 such that the connecting device 30 can be pivoted back to a position wherein the angle a approaches 0° and/or wherein the longitudinal axis L2 is substantially parallel to longitudinal LI. Finally, the connecting device 30 has access to the valve 23 and can be coupled to the valve 23.

The user attaches the lid to the housing 10 which in turn holds the gas and/or fuel reservoir device 20 in the coupled position. More specifically, the tensioning element of the lid may urge the gas and/or fuel reservoir device 20 along the longitudinal axis LI toward the connecting device 30. The tensioning element may be adapted to compensate for a difference in height of varying gas and/or fuel reservoir devices 20 in the housing recess 12. Although the above coupling is described for the nose 265, it should be understood that the connecting device 30 may be configured to get around any other structural component of the gas and/or fuel reservoir device 20 that may prevent direct access of the connecting device 30 to the valve 23.
