Description

TECHNICAL FIELD

[0001] The present disclosure relates to a charger for receiving an aerosol-generating article with an improved closing device, an aerosol-generating system comprising the charger, and a method of using the aerosol-generating system. BACKGROUND

[0002] Electrically operated aerosol-generating systems generally comprise an aerosol-forming substrate and an atomiser operated to atomise volatile compounds in the aerosol-forming substrate to form an aerosol for inhalation by a user. Typically, electrically operated aerosol-generating systems also comprise an aerosol-generating device comprising a power supply for supplying power to the atomiser. The atomiser can be an electrically operated heating device, such as an electric heater.

[0003] In some systems, the aerosol-generating device is configured to receive an aerosol-generating article comprising a solid aerosol-forming substrate, such as a substrate comprising homogenised tobacco. In these systems, the device typically comprises an atomiser and a power supply in the form of a rechargeable battery connected to the atomiser, the atomiser being arranged to heat the aerosol-forming substrate when the article is received in the device.

[0004] Some electrically operated aerosol-generating systems comprise a separate charger for releasably receiving and recharging the aerosol-generating device when it is not in use. Typically, the aerosol-generating device will be used frequently. For example, the aerosol-generating device can be used multiple times a day. Therefore, the user will frequently insert and remove the aerosol-generating device into the charger within a day.

[0005] In some aerosol-generating systems, the charger further comprises a lid. The lid is movable from an open position, in which the aerosol-generating device is receivable by the charger, to a closed position, in which the aerosol-generating device is protected from dust.

[0006] The charger typically comprises electrical contacts. The aerosol-generating device also typically comprises electrical contacts. In order to recharge the aerosol-generating device received in the charger, the aerosol-generating device should be positioned in the charger such that the electrical contacts of the aerosol-generating device are electrically connected with the electrical contacts of the charger when the aerosol-generating device is received in the charger. In the closed position, the lid also prevents the user from changing the position of the aerosol-generating device within the charger. However, the electrical connection can not be maintained at all times if the charger is stored in a particular orientation or dropped by the user of the device. If the electrical connection is not maintained at all times when the aerosol-generating device is received in the charger, the aerosol-generating device can not be recharged correctly. This risk is particularly high when the aerosol-generating system is a portable system. Furthermore, there is a risk that the lid can be accidentally forced from the closed position into the open position.

[0007] Furthermore, in many aerosol-generating systems, the lid in the open position is generally at risk of being damaged. This is especially the case if the lid protrudes from the charger in the open position. For example, the lid can be movable about a rotational axis, wherein in the closed position the lid is substantially parallel to and adjacent to a surface of the charger. After rotation about the rotational axis, the lid in the open position is substantially perpendicular to the surface of the charger. When the charger protrudes in this way perpendicularly, there is a risk of damage to the lid. SUMMARY

[0008] It is desirable to provide a charger that can allow reliable and efficient charging by ensuring an electrical connection between the charger and an aerosol-generating device received in the charger. In view of the frequency of use of aerosol-generating systems, it is desirable to provide a charger that can be quickly and simply manipulated by a user of the device. It is also desirable to provide a charger with a robust lid.

[0009] In the present disclosure, a charger for charging an aerosol-generating device is provided. The charger can comprise a housing. The housing can define a cavity for receiving an aerosol-generating device to be charged. The cavity can have an opening. At least one electrical contact can be located in the cavity. The charger can further comprise a lid. The lid can be slidable relative to the opening between an open position and a closed position. An inner surface of the lid can face the cavity when the lid is in the closed position. At least a portion of the inner surface of the lid can define a profiled engagement member. The profiled engagement member can have a leading edge and a trailing edge. The profiled engagement member can be inclined into or towards the cavity when the lid is in the closed position. The inclination can increase in a direction from the leading edge to the trailing edge of the profiled engagement member.

[0010] In one example, a charger for charging an aerosol-generating device comprises a housing defining a cavity for receiving an aerosol-generating device to be charged, the cavity having an opening; at least one electrical contact located in the cavity; and a lid slidable relative to the opening between an open position and a closed position, an inner surface of the lid facing the cavity when the lid is in the closed position, wherein: at least a portion of the inner surface of the lid defines a profiled engagement member having a leading edge and a trailing edge, the profiled engagement member being inclined into or towards the cavity when the lid is in the closed position, the inclination increasing in a direction from the leading edge to the trailing edge of the profiled engagement member.

[0011] When the cover is in the open position, an aerosol-generating device can be received in the cavity by the charger. When the cover is in the closed position, the aerosol-generating device received in the cavity is protected from surrounding dust and dirt. In the closed position, the cover also prevents a user from changing the position of the aerosol-generating device within the charger. Electrical contact between at least one electrical contact of the charger and the aerosol-generating device received in the charger is ensured. Advantageously, such a charger allows for reliable and efficient charging of the aerosol-generating device received in the cavity. Furthermore, advantageously, the slidable cover is robust.

[0012] When the cover is in the closed position, the profile engagement member being tilted into or towards the cavity advantageously allows for engagement of the aerosol-generating device received in the cavity. By engaging the aerosol-generating device, the profile engagement member advantageously holds the aerosol-generating device in a predetermined position within the cavity. In the predetermined position, the aerosol-generating device can be electrically connected with the charger. Irrespective of the orientation of the charger, or if a sudden force is applied to the charger, for example in case of a drop of the charger, the engagement of the profile engagement member with the aerosol-generating device can advantageously ensure the electrical connection between the aerosol-generating device and the charger.

[0013] The electrical connection between the aerosol-generating device and the charger can be achieved when the aerosol-generating device is in contact with the at least one electrical contact located in the cavity. In particular, electrical communication can be achieved when the at least one electrical contact on the aerosol-generating device is in contact with the at least one electrical contact located in the cavity.

[0014] As used herein, the term“profile engagement member” relates to a portion of the inner surface of the cover which is configured to engage a surface of the aerosol-generating device received in the cavity of the charger by contact with the surface of the aerosol-generating device when the cover is in the closed position. The profile engagement portion can engage the aerosol-generating device at some intermediate position of the cover, i.e. at a position between the open position and the closed position, and remain in engagement with the aerosol-generating device as the cover is slid from the intermediate position to the closed position.

[0015] As used herein, the term“inner surface of the cover” means the surface of the cover facing the housing of the charger. This inner surface faces the cavity defined in the housing of the charger when the cover is in the closed position.

[0016] The profile engagement member can be configured to urge the aerosol-generating device received in the cavity into engagement with the at least one electrical contact when the cover is in the closed position. This advantageously ensures that the electrical communication between the aerosol-generating device and the charger is maintained. By urging the aerosol-generating device into contact with the at least one electrical contact of the charger, the electrical resistance between the at least one contact and the aerosol-generating device can be significantly reduced. This can ensure efficient charging of the aerosol-generating device.

[0017] As used herein, the term "urge" or "urging" means a force applied by one component to another component.

[0018] The profile engagement member can protrude into or towards the cavity when the lid is in the closed position. The protrusion of the profile engagement member can increase in a direction from the leading edge to the trailing edge of the profile engagement member. This is a result of the inclination of the profile engagement member increasing into or towards the cavity from the leading edge to the trailing edge.

[0019] Preferably, the leading edge can extend into or towards the cavity insufficiently to engage the aerosol-generating device received in the cavity. Thus, the profile engagement member does not immediately engage the aerosol-generating device received in the cavity when the lid is slid from the open position to the closed position. As the lid continues to be slid towards the closed position, the profile engagement portion can protrude into or towards the cavity to an extent that it engages the aerosol-generating device received in the cavity and then incrementally urges the aerosol-generating device to an extent that it engages the at least one electrical contact. This configuration advantageously results in a smooth engagement of the profile engagement member with the aerosol-generating device.

[0020] Sliding the lid from the open position to the closed position can move the profile engagement member into an overlapping relationship with the cavity. In this overlapping relationship, the profile engagement member can advantageously interact with and engage the aerosol-generating device received in the cavity. The leading edge of the profile engagement member can first move into the overlapping relationship with the cavity as the lid is slid from the open position to the closed position.

[0021] The inclination of the profile engagement member can linearly increase into or towards the cavity from the leading edge to the trailing edge. Alternatively, the inclination can increase non-linearly. For example, the rate of change of the inclination can increase from the leading edge to the trailing edge. The increasing protrusion into or towards the cavity of such a lid can be slow at first and then increase more rapidly as the lid is slid from the open position. The non-linear inclination can be configured such that there is a smooth engagement of the profile engagement member when the rate of increase of the inclination is lower. After engagement, the aerosol-generating device can be pushed into the cavity rapidly to ensure electrical connection. Thus, the non-linear increase of the inclination of the profile engagement portion can reduce the necessary travel distance of the lid from the open position to the closed position.

[0022] Although reference is made throughout to the lid being slid from the open position to the closed position, the lid can equally be slid from the closed position to the open position.

[0023] Preferably, the at least one electrical contact of the charger is a resilient element.

[0024] As used herein, the term "resilient element" refers to an element that can be deformed or deflected under an applied force, but is able to return to its original position or state after the applied force is removed. When a resilient element is deformed or deflected under the action of a component moving an applied force towards the resilient element, the resilient element generates a counter force to urge the component away from the resilient element. Examples of resilient elements include coil springs and cantilever springs.

[0025] The at least one electrical contact can be a resilient element configured to apply a force to an aerosol-generating device received in the cavity in the direction of the cavity opening when the cover is in the closed position. The force applied by the resilient element advantageously urges the aerosol-generating device against the cover, and in particular against the profiled engagement member of the cover, when the cover is in the closed position. This advantageously ensures electrical communication between the aerosol-generating device and the charger when the cover is in the closed position.

[0026] The charger can comprise an aerosol-generating device release mechanism. The aerosol-generating device release mechanism can be located in the cavity. The aerosol-generating device release mechanism can comprise a resilient element. The aerosol-generating device release mechanism can be configured to urge an aerosol-generating device received in the cavity in the direction of the cavity opening when the cover is in the closed position. The aerosol-generating device release mechanism can be configured to at least partially urge the aerosol-generating device out of the cavity when the cover is in the open position. By urging the aerosol-generating device out of the cavity, a user of the device can more easily remove the aerosol-generating device from the charger.

[0027] This is because an area can be provided where a user can hold the aerosol-generating device. A user of the device can grasp this area and interact with it.

[0028] The aerosol-generating release mechanism can be a resilient element in the form of a coil spring or a cantilever spring located in the cavity of the charger.

[0029] The charging device can comprise a primary power source. The primary power source can be electrically coupled to the at least one electrical contact of the charger. The aerosol-generating device can comprise a secondary power source. The secondary power source can be electrically coupled to the at least one electrical contact of the aerosol-generating device.

[0030] The primary power source and the secondary power source can comprise any suitable type of power source. The primary power source and the secondary power source can comprise one or more of a battery and a capacitor. The primary power source and the secondary power source can comprise a lithium-ion battery. The primary power source and the secondary power source can be rechargeable power sources. The primary power source and the secondary power source can be the same. The primary power source and the secondary power source can be different. The primary power source can have a greater size or capacity than the secondary power source of the aerosol-generating device. This can allow electrical communication between the primary power source and the secondary power source when the charger and the aerosol-generating device are electrically connected. The electrical communication between the primary power source and the secondary power source can allow the primary power source to be used to recharge the secondary power source. Thus, the profile engagement member ensures that the connection between the aerosol-generating device and the charger advantageously ensures that the primary power source recharges the secondary power source when the aerosol-generating device is received in the charger and the lid is in the closed position.

[0031] The cavity of the charger can have a size that substantially corresponds to the size of the aerosol-generating device to be received in the cavity. Preferably, the cavity is an elongate cavity extending from the opening to a closed end. The length of the cavity from its opening to its closed end is preferably substantially similar to the length of the aerosol-generating device to be received in the cavity. The aerosol-generating device received in the cavity of the charger can extend out or over the opening of the cavity when received in the cavity. This extension out or over the cavity can be a result of at least one electrical contact of the charger pushing the aerosol-generating device out of the cavity.

[0032] The profile engagement member can be a cam surface. A surface of the aerosol-generating device received in the cavity can be a cam rider. In particular, a top surface of the aerosol-generating device can be the cam rider.

[0033] As used herein, the term“cam surface” refers to a surface of a first component configured to contact a portion of a second component. As used herein, the term“cam rider” refers to a portion of a second component configured to contact a cam surface. The cam surface and the cam rider are configured such that movement of the first component is transmitted to the second component by contact between the cam surface and the cam rider. Typically, the cam surface passes over the cam rider.

[0034] The profile engagement member, as a cam surface, can be configured to transmit a sliding movement of the lid to the aerosol-generating device, as a cam rider. As the lid moves from the open position to the closed position, the aerosol-generating device can follow or conform to the inclination of the profile engagement member. As the profile engagement member inclines into or towards the cavity, the aerosol-generating device is pushed in the direction towards the cavity as the lid moves from the open position to the closed position. This advantageously pushes the aerosol-generating device against the electrical contacts in the cavity.

[0035] The aerosol-generating device can only ride the profile engagement member after the profile engagement member engages the aerosol-generating device.

[0036] The lid that slides between the open position and the closed position is movable in a sliding plane.

[0037] As used herein, the term "sliding plane" refers to a plane in which the lid is located when the lid is in the closed position, the open position, or an intermediate position between the closed position and the open position. The sliding plane defines x and y directions in a Cartesian coordinate system. The lid can extend substantially in the x and y directions. The lid can slide in a direction along the x axis. In other words, the lid can slide linearly.

[0038] The direction of the inclination of the profile engagement member can be out of the sliding plane. The profile engagement member can be inclined into the cavity out of the sliding plane when the lid is in the closed position.

[0039] As used herein, the term "out of the sliding plane" means that a non-zero component of the inclination of the profile engagement member is in a direction that is normal to both the x direction and the y direction defined by the sliding plane. In other words, the non-zero component of the inclination of the profile engagement member is in the z direction in the Cartesian coordinate system defined by the sliding plane.

[0040] The cavity can define a longitudinal axis. The longitudinal axis can be parallel to a direction in which the aerosol-generating device is inserted into the cavity. The longitudinal axis can be parallel to the z direction defined above. Thus, the profile engagement member that is inclined into the cavity or towards the cavity is inclined towards the z axis.

[0041] The lid can comprise an outer surface that extends substantially parallel to the sliding plane. The outer surface can be located on a side of the lid that is opposite to the inner surface. The inner surface of the lid can comprise a portion that is not inclined into the cavity or towards the cavity when the lid is in the closed position. The portion of the inner surface of the lid can extend substantially parallel to the sliding plane. The portion of the inner surface of the lid can extend substantially parallel to the outer surface of the lid.

[0042] The housing of the charger comprises a front wall, a rear wall, a bottom wall, a top wall, a first side wall, and a second side wall. The charger housing can have a parallelepiped shape.

[0043] The terms "front", "rear", "upper", "lower", "side", "top", "bottom", "left", "right", and other terms used to describe the relative positions of the components of the charger and the aerosol-generating device refer to the charger having a cavity opening configured to receive the aerosol-generating device at a top end in an upright position. The cavity can be formed in the top end. The sliding plane described above can be substantially parallel to the top end. The lid can slide in a left-to-right direction relative to the top end.

[0044] The term "longitudinal" refers to a direction from the bottom to the top, and vice versa.

[0045] Advantageously, the slidable cover is robust. The slidable cover can be attached to a track formed in the housing of the charger. The track can extend parallel to a top surface of the charger. The cover can fit to the track.

[0046] The housing of the charger can comprise a face over which the cover can slide. The inner surface of the cover can not slide beyond the face of the housing when the cover is slid from the open position to the closed position. When in the open position, the cover can not protrude from the device and thus there is no position where the cover has an increased risk of damage. The face of the housing can lie in a plane substantially parallel to the aforementioned sliding plane. Advantageously, this arrangement is robust.

[0047] The charger can comprise an actuation member. The charger can comprise means to slide the cover from the open position to the closed position in response to the user of the charger manipulating the actuation member. By providing an actuation member to operate the cover, the process of opening and closing the charger is simplified, making it more comfortable for the user. For example, the actuation member on the charger housing can advantageously be positioned such that a user holding the charger in one hand can manipulate the actuation member using the same hand. This can be more comfortable than moving the cover itself. The actuation member can be positioned on a front side of the charger housing.

[0048] The actuation member can be a slider. The means to slide the cover can be a mechanical linkage between the slider and the cover. The mechanical linkage can directly transfer motion of the slider to the cover. The mechanical linkage can be a rigid shaft directly connecting the slider to the cover.

[0049] Alternatively, the actuation member can be a button or a switch. The means to slide the cover can comprise an actuator and a mechanical linkage between the actuator and the cover. The actuation member can be configured to send an electrical signal to the actuator in response to the actuation member being manipulated by the user of the charger. The actuator can be a linear actuator configured to move the cover from the open position to the closed position.

[0050] The means to slide the cover can comprise a locking mechanism configured to prevent the cover being slidable from the closed position to the open position without the actuation member being manipulated by the user of the charger. Advantageously, the locking mechanism prevents the user accidentally forcing the cover from the closed position to the open position, for example if the charger is stored in the user’s pocket.

[0051] The locking mechanism can comprise a locking pin configured to engage the cover when the cover is in the closed position to prevent the cover being slidable and disengage in response to the actuation member being manipulated by the user of the charger. The locking pin can disengage the cover when the means to slide the cover moves the cover from the closed position to the open position. The means to slide the cover can first move a cam which disengages the locking pin. Advantageously, the locking pin being operated by the actuation member allows the user to both unlock and slide the cover in one action.

[0052] The lid can be biased towards the closed position. The lid can be biased towards the closed position by a spring, the spring being attached to the lid at a first end of the spring and to the housing of the charger at a second end of the spring. Advantageously, the lid being biased to the closed position means that the position of the lid is urged towards the closed position. Whenever the lid is in the open position, the biasing force can urge the lid back to the closed position without requiring the user to manipulate the actuation element. This advantageously prevents the user from inadvertently leaving the lid in the open position. This also advantageously means that if the lid is accidentally forced open, for example when the charger is stored in the user's pocket, it will automatically close again.

[0053] As used herein, the term "aerosol-generating device" refers to a device that interacts with an aerosol-forming substrate to generate an aerosol that can be inhaled directly into the lungs of a user through the mouth of the user. In certain embodiments, the aerosol-generating device can heat the aerosol-forming substrate to promote the release of volatile compounds. The aerosol-generating device can interact with an aerosol-generating article comprising an aerosol-forming substrate or a cartridge comprising an aerosol-forming substrate. An electrically operated aerosol-generating device can comprise an atomizer, such as an electric heater, to heat the aerosol-forming substrate to form an aerosol.

[0054] As used herein, the term 'aerosol-forming substrate' is used to describe a substrate that is capable of releasing, upon heating of volatile compounds, to form an aerosol. The aerosol produced by the aerosol-forming substrate of the aerosol-generating article described herein can be visible or invisible, and can include vapour (e.g. fine particulate matter in a gaseous state, which is typically a liquid or solid at room temperature) as well as gas and droplets of condensed vapour.

[0055] The aerosol-forming substrate can be a solid aerosol-forming substrate. The aerosol-forming substrate can comprise both a solid component and a liquid component.

[0056] Preferably, the aerosol-forming substrate comprises nicotine. More preferably, the aerosol-forming substrate comprises tobacco.

[0057] Alternatively or additionally, the aerosol-forming substrate can comprise a non-tobacco containing aerosol-forming material.

[0058] If the aerosol-forming substrate is a solid aerosol-forming substrate, the solid aerosol-forming substrate can comprise, for example, one or more of a powder, a granule, a pellet, a shard, a fine strip, a strip or a sheet material containing one or more of a herbal plant leaf, a tobacco leaf, a tobacco rib filler, a flat expanded tobacco and a homogenised tobacco.

[0059] Optionally, the solid aerosol-forming substrate can contain tobacco or non-tobacco volatile flavour compounds which are released upon heating the solid aerosol-forming substrate. The solid aerosol-forming substrate can also comprise one or more capsules, for example including additional tobacco volatile flavour compounds or non-tobacco volatile flavour compounds, and such capsules can melt during heating of the solid aerosol-forming substrate.

[0060] Optionally, the solid aerosol-forming substrate can be provided on or embedded in a thermally stable carrier. The carrier can take the form of a powder, a granulate, a pellet, a shard, a fine rod, a rod or a sheet. The solid aerosol-forming substrate can be deposited on the surface of the carrier in the form of, for example, a sheet, a foam, a gel or a slurry. The solid aerosol-forming substrate can be deposited over the entire surface of the carrier, or alternatively, can be deposited in a pattern so as to provide for non-uniform flavour delivery during use.

[0061] If the aerosol-forming substrate is a liquid, the aerosol-generating article or cartridge can comprise means for holding the liquid substrate. The aerosol-forming substrate can alternatively be any other kind of substrate, for example a gaseous substrate, a gel substrate or any combination of the various types of substrate.

[0062] Preferably, the aerosol-forming substrate comprises an aerosol-forming agent.

[0063] As used herein, the term "aerosol-forming agent" is used to describe any suitable known compound or mixture of compounds which, in use, facilitates the formation of an aerosol and which is substantially resistant to thermal degradation at the operating temperature of the aerosol-generating article.

[0064] Suitable aerosol-forming agents are known in the art and include, but are not limited to: polyhydric alcohols, for example propylene glycol, triethylene glycol, 1,3-butanediol and glycerol; esters of polyhydric alcohols, for example glycerol monoacetate, glycerol diacetate or glycerol triacetate; and aliphatic esters of mono-, di- or poly-carboxylic acids, for example dimethyl dodecanedioate and dimethyl tetradecanedioate.

[0065] A preferred aerosol-forming agent is a polyhydric alcohol or a mixture thereof, such as propylene glycol, triethylene glycol, 1,3-butanediol and most preferably glycerol.

[0066] The aerosol-forming substrate can comprise a single aerosol-forming agent. Alternatively, the aerosol-forming substrate can comprise a combination of two or more aerosol-forming agents.

[0067] Preferably, the aerosol-forming substrate has an aerosol-forming agent content of greater than 5% by dry weight.

[0068] The aerosol-forming substrate can have an aerosol-former content of between about 5% and about 30% by dry weight.

[0069] In a preferred embodiment, the aerosol-forming substrate has an aerosol-former content of about 20% by dry weight.

[0070] In the present disclosure, there is also provided an aerosol-generating system comprising a charger and an aerosol-generating device; the charger comprising a housing defining a cavity for receiving the aerosol-generating device, the cavity having an opening; at least one electrical contact located in the cavity; and a cover slidable relative to the opening between an open position and a closed position, an inner surface of the cover facing the cavity when the cover is in the closed position, wherein: at least a portion of the inner surface of the cover defines a profiled engagement member having a leading edge and a trailing edge, the profiled engagement member being inclined into or towards the cavity when the cover is in the closed position, the inclination increasing in a direction from the leading edge to the trailing edge of the profiled engagement member; wherein the profiled engagement member is configured to urge the aerosol-generating device into engagement with the at least one electrical contact when the cover is in the closed position and the aerosol-generating device is received in the cavity.

[0071] The features of the charger described above can apply to the charger of the aerosol-generating system.

[0072] The aerosol-generating device can be received in the cavity by the charger when the cover of the charger is in the open position. When the cover is in the closed position, the aerosol-generating device is protected from surrounding dust and dirt. In the closed position, the cover also prevents the user from changing the position of the aerosol-generating device within the charger and ensures electrical contact between the at least one electrical contact of the charger and the aerosol-generating device. Advantageously, such a charger allows reliable and efficient charging of the aerosol-generating device received in the cavity.

[0073] The urging of the aerosol-generating device into engagement with the at least one electrical contact ensures that electrical communication between the aerosol-generating device and the charger is maintained.

[0074] The at least one electrical contact of the charger can be a resilient element. The resilient element can be configured to exert a force on the aerosol-generating device received in the cavity in the direction of the cavity opening when the cover is in the closed position.

[0075] The charger can comprise an aerosol-generating device release mechanism. The aerosol-generating device release mechanism can be located in the cavity. The aerosol-generating device release mechanism can comprise a resilient element.

[0076] Sliding the cover from the open position to the closed position can move the profiled engagement member into overlapping relationship with the cavity. The leading edge of the profiled engagement member can be the first to move into overlapping relationship with the cavity as the cover is slid from the open position to the closed position.

[0077] The charging device can comprise a primary power source. The primary power source can be electrically coupled to the at least one electrical contact of the charger. The aerosol-generating device can comprise a secondary power source. The secondary power source can be electrically coupled to the at least one electrical contact of the aerosol-generating device. Electrical communication between the primary power source and the secondary power source can allow the primary power source to be used to recharge the secondary power source. Thus, the profile engagement member ensures that the connection between the aerosol-generating device and the charger advantageously ensures that the primary power source recharges the secondary power source when the aerosol-generating device is received in the charger and the lid is in the closed position.

[0078] The cavity of the charger can have dimensions that substantially correspond to the dimensions of the aerosol-generating device to be received in the cavity. The length of the cavity from its opening to its closed end is preferably substantially similar to the length of the aerosol-generating device to be received in the cavity.

[0079] The profile engagement member can protrude into or towards the cavity when the lid is in the closed position.

[0080] The profile engagement member can be a cam surface and the surface of the aerosol-generating device received in the cavity can be a cam follower.

[0081] The lid that slides between the open and closed positions can move in a sliding plane.

[0082] The charger can comprise an actuation member. The charger can comprise means to slide the lid from the open position to the closed position in response to a user manipulating the actuation member of the charger.

[0083] The actuation member can be a slider. The means to slide the lid can be a mechanical linkage between the slider and the lid.

[0084] Alternatively, the actuation member can be a button or a switch. The means to slide the lid comprises an actuator and a mechanical linkage between the actuator and the lid.

[0085] The lid can be biased towards the closed position. The lid can be biased towards the closed position by a spring attached to the lid at a first end of the spring and to the housing of the charger at a second end of the spring.

[0086] In the present disclosure, a method of using an aerosol-generating system is provided, the aerosol-generating system comprising a charger and an aerosol-generating device; the charger comprising: a housing defining a cavity for receiving the aerosol-generating device, the cavity having an opening; at least one electrical contact located in the cavity; and a cover slidable relative to the opening between an open position and a closed position, an inner surface of the cover facing the cavity when the cover is in the closed position, wherein: at least a portion of the inner surface of the cover defines a profiled engagement member having a leading edge and a trailing edge, the profiled engagement member being inclined into or towards the cavity when the cover is in the closed position, the inclination increasing in a direction from the leading edge to the trailing edge of the profiled engagement member; the method comprising:

[0087] inserting the aerosol-generating device into the cavity of the charger when the cover is in the open position; and

[0088] sliding the cover from the open position to the closed position;

[0089] wherein in the closed position, the profiled engagement member of the cover urges the aerosol-generating device into engagement with the at least one electrical contact.

[0090] The method can comprise the step of sliding the cover from the closed position to the open position before inserting the aerosol-generating device into the cavity.

[0091] The charger can charge the aerosol-generating device when the aerosol-generating device is received in the cavity and the cover is in the closed position. A controller in the charger can couple a main power supply of the charger with the at least one electrical contact of the charger. The aerosol-generating device in engagement with the at least one electrical contact can be in electrical communication with the at least one electrical contact, for example, via at least one electrical contact on the aerosol-generating device. Thus, a secondary power supply located in the aerosol-generating device can be charged by the main power supply of the charger. The charging of the aerosol-generating device can be regulated by the controller of the charger.

[0092] The method can further comprise the step of sliding the cover from the closed position to the open position when a user wants to use the aerosol-generating device received in the charger.

[0093] The charger can comprise an aerosol-generating device release mechanism. The aerosol-generating device release mechanism can push the aerosol-generating device out of the cavity of the charger when the cover is slid to the open position. This can advantageously push a portion of the aerosol-generating device out of the cavity. A user of the aerosol-generating system can use this portion to pull the aerosol-generating device out of the cavity.

[0094] The step of sliding the lid from the open position to the closed position (or vice versa) can comprise the user directly manipulating the lid of the charger. Alternatively, the charger can comprise an actuation member in the form of a slider, switch or button, manipulation of which operates the lid. Manipulation of the actuation member can cause the lid to slide from the open position to the closed position.

[0095] The lid can be biased towards the closed position. The step of inserting the aerosol generating device into the device cavity can comprise exerting a force on the lid against the biasing element to hold the lid in the open position. This force can be exerted directly on the lid by the user. Alternatively, the force can be exerted via the device to slide the lid. The step of sliding the lid from the open position to the closed position can comprise removing the force holding the lid in the open position, such that the lid automatically moves to the closed position due to the biasing element.

[0096] Features described in relation to one example or embodiment can also be applicable to other aspects and embodiments. For example, features described in relation to the aerosol generating article and the aerosol generating system as described above can also be used in combination with methods of using the aerosol generating article and the aerosol generating system as described above.

[0107] Figure 1 a schematic diagram of a known electrically operated aerosol-generating system is shown. The known electrically operated aerosol-generating system comprises a charger 1, an aerosol-generating device 20 and an aerosol-generating article 30.

[0108] The charger 1 comprises a housing 2 having the overall dimensions and shape of a conventional cigarette pack. A lithium-ion battery 3 and circuitry 4 are housed within the charger 1. The charger 1 further comprises a generally cylindrical cavity 5 for receiving an aerosol-generating device 20. The cavity 5 is defined by the housing 2. Electrical contacts (not shown) are arranged at the closed end of the cavity 5 for electrically connecting an aerosol-generating device received in the cavity 5 to the battery 3 of the charging device 1.

[0109] The aerosol-generating device 20 is substantially cylindrical and has the overall dimensions of a conventional cigar. The length of the device 20 is substantially the same as the length of the cavity 5 and the diameter of the device 20 is slightly smaller than the diameter of the cavity 5 so that the device 20 fits snugly in the cavity 5. The aerosol-generating device 20 comprises an open cavity 21 at the proximal end for receiving an aerosol-generating article. The aerosol-generating device 20 further comprises a battery (not shown) housed in the housing of the device and an electric heater (not shown) arranged in the cavity 21 for heating at least a portion of the aerosol-generating article 30 when the aerosol-generating article 30 is received in the cavity 21.

[0110] The aerosol-generating article 30 comprises an aerosol-forming substrate (not shown) comprising a mass of crimped tobacco sheet and a filter (not shown) arranged back-to-back with the aerosol-forming substrate in the form of a rod. The aerosol-generating article 30 has a diameter substantially equal to the diameter of the cavity 21 of the device 20 and a length longer than the length of the cavity 21 so that when the article 30 is received in the cavity 21 of the device 20, the filter protrudes from the cavity 21 and can be drawn upon by a user, similar to a conventional cigarette.

[0111] In use, a user inserts the article 30 into the cavity 21 of the device 20 and turns on the device 20 to activate the electric heater. The electric heater heats the aerosol-forming substrate of the article 30 so that volatile compounds of the aerosol-forming substrate are released and aerosolised to form an aerosol. The user draws on the mouthpiece of the article 30 and inhales the aerosol generated from the heated aerosol-forming substrate. After use of the device 20, the article 30 can be removed from the device 20 for disposal and the device 20 can be placed in the charger 1 for storage and to charge the battery of the device 20.

[0112] Figure 2 A perspective view of a charger 100 according to the present application is shown. The charger 100 comprises a charger housing 102 and a lid 110. The charger housing 102 has a parallelepiped shape. A cavity 120 for receiving an aerosol-generating device is defined in the charger housing 102. The cavity 120 comprises a cavity wall 122 and a cavity opening 124 defined in a top surface 104 of the charger housing 102. The charger further comprises two electrical contacts (not shown in the middle) and a power source in the form of a rechargeable battery (not shown) within the cavity. The rechargeable battery is couplable to the electrical contacts located in the cavity. Figure 2 The charger 100 further comprises a power source in the form of a rechargeable battery (not shown in the middle) and two electrical contacts (not shown in the middle) located in the cavity. The rechargeable battery is couplable to the electrical contacts located in the cavity.

[0113] The charger housing 102 defines a track 112 which extends slightly above the top surface 104 of the charger housing 102 on either side of the cavity 120. A lid 110 is attached to the track 112 such that the lid can slide along the track 112. A stop (not shown) at either end of the track prevents the lid 110 from sliding beyond the end of the track 112, and thus beyond the top surface 104 of the charger housing 102. As can be seen in Figure 1 Fig. a, the lid 110 does not protrude beyond the top surface in the open or closed positions of the lid.

[0114] The lid 110 can slide between an open position (shown in Figure 2 Fig. a) and a closed position (shown in Figure 2 Fig. b). In the open position, the cavity 120 is accessible such that an aerosol-generating device can be received in the cavity 120 by the charger 100. In the closed position, the lid 100 closes the cavity 120 by facing the cavity opening 124. Closing the cavity protects the cavity 120 from dust and prevents a user from changing the position of an aerosol-generating device received within the cavity 120 of the charger 100. The charger housing 102 acts as a shell to receive the aerosol-generating device and provides protection for the aerosol-generating device received in the cavity. The lid 110 also serves to ensure electrical contact between the aerosol-generating device received in the cavity and the electrical contacts of the charger (not shown in Figure 2 Fig. a) located in the cavity 120. This is described in more detail below in relation to Figure 3 Fig. b.

[0115] Figure 3 A cross-sectional view of the charger 100 is shown with an aerosol-generating device 300 received in the cavity 120. Figure 3 Fig. a shows the lid 110 in the open position, and Figure 3 Fig. b shows the lid 110 in the closed position. The lid 110 comprises an inner surface 310, a portion of which defines a profiled engagement member 312. The profiled engagement member 312 comprises a front edge 314 and a rear edge 316. As Figure 3 Fig. b shows, the profiled engagement member 312 is inclined towards the cavity when the lid is in the closed position. The inclination of the profiled engagement member 312 increases in a direction from the front edge 314 to the rear edge 316.

[0116] The aerosol-generating device comprises two electrical contacts 302, 303. The aerosol-generating device also comprises a power source in the form of a rechargeable battery (not shown). The rechargeable battery of the aerosol-generating device can be electrically coupled with the two electrical contacts 302 and 303.

[0117] Two electrical contacts, 304 and 305, are located within the charger's cavity. When the aerosol generating device is received within the cavity, its electrical contacts 302 and 303 align with the charger's contacts 304 and 305. When an electrical connection is established between the charger's electrical contacts and the aerosol generating device's electrical contacts, the charger's rechargeable battery can be used to recharge the aerosol generating device's rechargeable battery. For reliable charging of the rechargeable battery, the electrical connection must remain consistent.

[0118] Electrical contacts 304 and 305 are elastic elements in the form of cantilever springs.

[0119] like Figure 3 As shown in Figure a, the electrical contacts extend upward from the closed end of the cavity in the direction of the cavity opening. When the cover 110 is open and assuming the charger remains upright, the aerosol generating device 300 rests on the electrical contacts 304 and 305. The aerosol generating device 300 has a length substantially the same as the length of the cavity (from the closed end of the cavity to the cavity opening). However, due to the upward extension of the electrical contacts 304 and 305, when the cover is in the open position, the aerosol generating device received in the cavity and resting on the electrical contacts 304 and 305 extends above the level of the cavity opening 322.

[0120] When the cover is in the open position, the electrical connection between electrical contacts 302 and 304 and 303 and 305 cannot be guaranteed and may therefore not be consistent. For example, if the charger 100 is not stored in an upright position, or is shaken or dropped, the electrical connection between the charger's electrical contacts and the device's electrical contacts may not be maintained.

[0121] When the cover 110 is in the closed position, electrical continuity is ensured between electrical contacts 302 and 304, and 303 and 305. This is because, in the closed position, the contour engagement member 312 of the cover 110 engages with the top surface 322 of the aerosol generating device 300 received in the cavity 120. This engagement ensures electrical continuity between the aerosol generating device 300 and the charger's electrical contacts 304 and 305, regardless of the charger's orientation or any sudden force applied to the charger (e.g., in the event of the charger being dropped). In other words, the engagement ensures that contact is maintained between the charger's electrical contacts 302 and 303 and the aerosol generating device's electrical contacts 304 and 305.

[0122] The reason for ensuring electrical communication is that the profile engagement member 312 pushes the aerosol-generating device into contact with the contacts of the charger 304 and 305 when the lid is in the closed position. The profile engagement member 312 exerts a force on the top surface 322 of the aerosol-generating device, pushing it into the cavity and pushing and abutting against the electrical contacts 304 and 305 in the direction of the electrical contacts. The force exerted causes the electrical contacts 304 and 305 to deform and generate a reaction force that pushes the aerosol-generating device 300 away from the electrical contacts (i.e. a reaction force that pushes the aerosol-generating device back out of the cavity 120). When the lid is in the closed position, the force exerted by the electrical contacts 304 and 305 pushes the aerosol-generating device against the lid, and in particular against the profile engagement member of the lid. This ensures contact between the aerosol-generating device 300 and the electrical contacts of the charger 304 and 305.

[0123] In Figure 3 In the illustrated embodiment, the profile engagement member 312 is configured to first engage the top surface 322 of the aerosol-generating device 300 received in the cavity 120 at an intermediate position of the lid (i.e. a position between the open and closed positions). This intermediate position is at Figure 3 c. As described in relation to Figure 2 The lid 110 is slidable on the track 112 between the open and closed positions. As the lid is slid along the track 112 towards the closed position, the profile engagement member 312 moves into overlapping relationship with the cavity 120. The leading edge 314 is the first to move into overlapping relationship with the cavity 120. Due to the inclination of the profile engagement member 312, the profile engagement member 312 protrudes increasingly towards the cavity as the lid is moved from the open position to the closed position. In Figure 3 c, the overlapping relationship of the profile engagement member 312 with the cavity 120 is such that the profile engagement member protrudes sufficiently towards the cavity to first contact and engage the top surface 322 of the aerosol-generating device 300. This arrangement results in a smooth engagement between the profile engagement portion and the aerosol-generating device.

[0124] As the lid is slid from the intermediate position illustrated in Figure 3 c to the closed position illustrated in Figure 3 b, the profile engagement member 312 and the aerosol-generating device 300 remain engaged. As the profile engagement member 312 protrudes increasingly towards the cavity, an increasing force is exerted on the aerosol-generating device to push the aerosol-generating device into contact with the electrical contacts 304 and 305. In turn, the electrical contacts 304 and 305 deform increasingly from their extended state and thus exert an increasing reaction force to push the aerosol-generating device back out of the cavity.

[0125] After the incline of the profiled engagement portion, the profiled engagement member 312 acts as a cam surface and the aerosol-generating device 300 acts as a cam rider. As the lid is slid from the open position to the closed position, the lateral movement of the profiled engagement member 312 is translated into a longitudinal movement of the aerosol-generating device into the cavity.

[0126] In the embodiments described so far, the lid 110 is slid from the open position to the closed position when the user directly manipulates the lid. Figure 4 A perspective view of an embodiment of the charger is shown in which the user instead manipulates an actuation member rather than directly manipulating the lid. Manipulation of the actuation member causes the lid to slide from the open position to the closed position (and vice versa).

[0127] In Figure 4 , the actuation member is in the form of a slider tab 402 and an elongate opening in the charger housing 404. The slider tab 402 is coupled to the lid 110 such that sliding the slider tab 402 causes the lid 110 to slide. The slider tab 402 can be slid along the elongate opening 404 from a first position in which the lid is in Figure 4 a shown open position to a second position in which the lid is in Figure 4 b shown closed position.

[0128] Figure 5 A cross-sectional view of the charger of Figure 4 is shown, showing the linkage between the slider tab 402 and the lid 110. Figure 5 a shows the lid 110 in the open position. Figure 5 b shows the lid in the closed position. The linkage between the slider tab 402 and the lid 110 is via a shaft 502 and is a direct mechanical linkage. When the slider tab 402 is moved, this moves the lid. The charger housing defines a hollow space 504. The shaft can move through this hollow space when the slider tab 402 is manipulated.

[0129] In some embodiments, the actuation member is a button or switch (not shown) rather than a slider tab and an elongate opening. The button or switch can be positioned on the charger housing. The user can manipulate the button or switch to operate an actuator positioned in the charger housing. The manipulation can be performed by pressing the button or toggling the switch. Pressing the button or toggling the switch sends a signal to a controller (not shown). The controller then controls the actuator to move the lid from the open position to the closed position in response to this manipulation.

[0130] Figure 6 A cross-sectional view of the charger is shown including an actuator in the form of a linear actuator 602 and including a piston rod 604. A direct mechanical linkage in the form of a rigid shaft 606 connects the piston rod 604 with the lid 110. Figure 6a shows the lid in an open position. Figure 6 b shows the lid in a closed position. The linear actuator 602 is configured to receive an electrical signal from a button or switch via a controller. When the user presses the button or switches the switch, the controller causes the linear actuator 602 to extend or retract the piston rod 604 as required. This in turn moves the lid from the open position to the closed position and vice versa. The linear actuator is connected to a rechargeable battery of the charger (not shown). The rechargeable battery provides power to the linear actuator. The charger housing defines a hollow space 608. The rigid shaft 606 can move through this hollow space when the slider tab 502 is manipulated.

[0131] Figure 7 An embodiment of a charger is shown that includes a biasing element in the form of a spring 702. The spring 702 is attached to the charger housing 102 at a first end 704 and to the lid 110 at a second end 706. Figure 7 a shows the lid of the charger in an open position. When the lid is in the open position, the spring 702 is compressed. In other words, the spring 702 is deformed when the lid is in the open position. As a result, the spring exerts a force on the lid, pushing the lid towards the closed position. The lid is pushed back each time it is in the open position, or in an intermediate position between the open and closed positions. This can prevent a user of the charger from inadvertently leaving the lid in the open position. If the lid is accidentally forced open, the biasing element will automatically close the lid again.

[0132] Figure 7 b shows the lid of the charger in a closed position. In the closed position, the spring 702 is in an undeformed state. Alternatively, the spring 702 can still be deformed, although to a lesser extent than when the lid is in the open state. In this arrangement, the lid is urged to remain closed even when it is in the closed position. This makes it more difficult for the lid to be accidentally forced open.

[0133] Figure 8 A cross-sectional schematic view of a charger including an aerosol-generating device release mechanism is shown, with the lid shown in an open position. The aerosol-generating device release mechanism is a coil spring 802 located in the cavity 120 between the electrical contacts 304 and 305. The coil spring is configured to push the aerosol-generating device 300 out of the cavity 120 (i.e. above the cavity opening 124) when the lid is in the open position. The spring 802 pushes on a bottom surface 804 of the aerosol-generating device 300. By pushing the aerosol-generating device out of the cavity, a user of the device can more easily remove the aerosol-generating device from the charger. This is because a portion of the aerosol-generating device is provided that the user can hold.

[0134] As described in relation to the previous embodiment, when the cover is in the closed position, the spring 802 is compressed and the aerosol-generating device is pushed against the electrical contacts 304 and 305. However, in order to close the cover, a user of the device needs to manually push the aerosol-generating device 300 below the level of the cover 110 so that the profiled engagement member 312 can be moved into overlapping relationship with the cavity opening.

[0135] Figure 9 is a flowchart outlining a method of using an aerosol-generating system according to the present disclosure.

[0136] At step 902, an aerosol-generating device is received into the cavity of the charger. This is when the cover is in the open position.

[0137] At step 904, a user slides the cover from the open position to the closed position. As described, as the cover is slid from the open position to the closed position, the cover engages the aerosol-generating device. In the closed position, the cover pushes the aerosol-generating device into engagement with the at least one electrical contact. This ensures that the electrical connection between the aerosol-generating device and the charger is maintained. This allows the aerosol-generating device to be charged by the charger. When the cover is closed, it protects the cavity and the aerosol-generating device received in the cavity from dust from the surrounding environment.

[0138] At step 906, the user slides the cover from the closed position to the open position. The user does this to be able to access the aerosol-generating device received in the cavity (according to step 908).

[0139] In some embodiments, the cover is biased closed. In these embodiments, the movable element automatically returns from the open position to the closed position. Therefore, step 904 can be automatic.

[0140] In the open position, the aerosol-generating device release mechanism pushes the aerosol-generating device out of the cavity. By pushing the aerosol-generating device out of the cavity, a portion of the aerosol-generating device extends out of the cavity. This portion can be used by a user of the aerosol-generating system to assist in removing the aerosol-generating device. When the charger comprises an aerosol-generating device release mechanism, step 904 can require the user to manually push the aerosol-generating device into the cavity before sliding the cover to the closed position to compress the aerosol-generating device release mechanism.
