    [001] The present invention relates to containers for an aerosol generating substrate and to a method of manufacturing such containers. The invention further relates to electrically heated aerosol generating devices configured for use with the containers.
    [002] Aerosol generating systems comprising aerosol generating containers and devices are known. A particular system is disclosed in WO 2009/079641 and comprises a container comprising a cover containing vaporizable viscous material and an aerosol former such as propylene glycol. The cover is sealed by a cap which can be penetrated by the aerosol generating device when the container is inserted therein to allow air flow through the container when in use. The device comprises a heater configured to heat the outer surface of the cover to a temperature of up to about 200°C and, in one example, the outer surface of the cover is heated to 170°C. The aerosol generating device is elongated and similar in diameter to a conventional combustible smoking article (a cigarette) and as such, the heater is necessarily in close proximity to the outer wall of the device. It has been found that the proximity of the heater to the external wall of the device results in an external temperature of the device housing in the heater region of over 90 degrees. At the very least, this can be uncomfortable for the user. In addition, it has been found that the time for the first drag of the device is up to 30 seconds.
    [003] Thus, it would also be desirable to provide a container that enhances the heating of the aerosol forming substrate.
    [004] In accordance with one aspect of the present invention, there is provided a container for an aerosol generating substrate, the container having a puncturing area, for use in an electrically heated aerosol generating device having a piercing element for puncturing the area of puncture. drilling. The container comprises: a wrapper; and a cover including the puncture area and a heater, the heater defining the boundary of the puncture area.
    [005] Advantageously, to provide a heater in the lid, arranged to allow the lid to be pierced, allowing heat to be applied more efficiently to the container. Providing the puncture area allows the lid to be punctured to allow a generated aerosol to be released from the container without damaging the heater.
    [006] The heater preferably has an inner edge and an outer edge, where the inner edge of the heater defines the boundary of the perforation area. Alternatively, the outer edge of the heater defines the boundary of the perforation area.
    [007] The heater is preferably arranged within an annular portion of the lid. Therefore, the central portion of the lid is preferably free from the heater and therefore can be pierced without damaging the heater. Positioning the heater on an annular portion of the cap can increase the size of the puncture area. The annular portion is preferably adjacent to the outer edge of the cap.
    [008] The heater is preferably provided in a waveform within the annular portion of the lid, so that the total length of the heater is greater than the circumferential length of the annular portion. Advantageously, increasing the length of the heater improves heat transfer from the heater to the aerosol forming substrate. The waveform can be a triangle wave, a square wave, or a sine wave.
    [009] The heater preferably comprises two electrical contacts, the first electrical contact at a first distance from an edge of the cover and the second electrical contact at a second distance from an edge of the cover. By providing the electrical contacts in this arrangement, the container can be placed in an aerosol generating device in any rotational orientation, while still allowing the correct electrical connections to be made.
    [0010] The container shell preferably has a substantially circular cross-sectional shape. By providing a substantially circular cross-sectional shape, the container can be more easily inserted into a cavity of an aerosol generating device. However, any other suitable cross-sectional shape can be provided, such as an elliptical.
    [0011] The material used to form the container shell can be metal, preferably aluminum. Alternatively, the material used to form the shell may be polymeric, such as any suitable polymer capable of withstanding the operating temperature of an aerosol forming device.
    [0012] The lid is preferably made of a polymer or a metal, and more preferably it is made of aluminium. The lid may be laminated to improve sealability and, in a particularly preferred embodiment, is laminated anodized, food-grade aluminum.
    [0013] The lid may be sealed to the container shell using any suitable method, including: adhesive, such as an epoxy adhesive; heat sealing; ultrasonic welding; and laser welding.
    [0014] The heater preferably comprises at least one strip with electrical resistance provided on a flexible substrate. Providing the heater on a flexible substrate allows the heater to be applied to the lid more easily and increases the heater's durability. In the present embodiment, the lid is preferably formed as a laminate comprising the flexible substrate. The laminate preferably further comprises a layer of a perforable sheet material, the sheet may be a metal, preferably aluminium. Alternatively, the sheet may be polymeric.
    [0015] Preferably, the electrically resistant strip is adhered to the flexible substrate using any suitable means.
    [0016] The range with electrical resistance can be any of the following: stainless steel, copper, bronze, platinum, gold and silver; or any other resistive material that can provide a sufficiently high temperature when supplied with an electrical current during operation so that a sufficiently dense aerosol is formed.
    [0017] By providing the heater in the lid on a flexible substrate, the manufacturing process can be simplified. The manufacturing process is described below in more detail.
    [0018] The or each electric heating element preferably has an elongated cross-section. When the aerosol generating substrate is a liquid, providing the elongated cross-sectional profile increases the volume of liquid in contact with the heater and therefore the heater is more efficient. A conventional heater, with a coil of wire as the heating element, usually has a circular or oval cross-section shape, and a meniscus of the liquid may form only on the sides of the wire. In comparison, the elongated cross-sectional profile of the present invention allows a meniscus of the liquid to form both on both sides of the heater and on the top surface.
    [0019] The elongated transverse profile is preferably rectangular. A rectangular cross-sectional shape is easier to manufacture and therefore reduces costs.
    [0020] The electrical resistance of the or each heater is preferably between 0.3 and 4 Ohms. More preferably, the electrical resistance of the or each heater is between 0.5 Ohms and 3 Ohms, and most preferably is about 1 Ohms. The electrical resistance of the or each heater is preferably at least one order of magnitude and more preferably at least two orders of magnitude greater than the electrical resistance of the contacting parts. This ensures that the heat generated by passing current through the heating element is located in the heater. It is generally advantageous to have a low overall resistance to the heater if the system is battery powered. A low resistance, high current system allows high energy distribution to the heater. This allows the heater to get the electrically conductive filaments to a desired temperature quickly.
    [0021] As used herein, the term "longitudinal" refers to the direction between the proximal end and the opposite distal end of the container, and refers to the direction between the proximal end, or mouthpiece, and the distal end of the generating device. of aerosol.
    [0022] The aerosol forming substrate is preferably a substrate capable of releasing volatile compounds that can form an aerosol. Volatile compounds are released by heating the aerosol-forming substrate.
    [0023] The aerosol forming substrate may be solid or liquid or comprises solid and liquid components. In a preferred embodiment, the aerosol forming substrate is solid.
    [0024] The aerosol forming substrate may comprise nicotine. The nicotine-containing aerosol forming substrate may be a nicotine salt matrix. The aerosol forming substrate may comprise a plant-based material. The aerosol-forming substrate may comprise tobacco, and preferably the tobacco-containing material contains volatile tobacco flavor compounds, which are released from the aerosol-forming substrate upon heating. The aerosol forming substrate may comprise a homogenized tobacco material.
    [0025] The container preferably comprises an aerosol-forming substrate comprising nicotine, wherein, when in use, the aerosol-forming substrate is accessible once the puncturing area has been pierced.
    [0026] The aerosol forming substrate may alternatively comprise a non-tobacco-containing material. The aerosol forming substrate may comprise a homogenized plant-based material.
    [0027] The homogenized tobacco material can be formed by agglomerating the individualized tobacco. When present, the homogenized tobacco material may have an aerosol former content equal to or greater than 5% on a dry weight basis and preferably between more than 5% and 30% by weight on a dry weight basis.
    [0028] The aerosol forming substrate may comprise at least one aerosol former. The aerosol former may be any suitable and known compound or mixture of compounds which, when in use, facilitates the formation of a dense, stable aerosol and which is substantially resistant to thermal degradation at the operating temperature of the aerosol generating device. Suitable aerosol formers are well known in the art and include, but are not limited to: polyhydric alcohols such as triethylene glycol, 1,3-butanediol and glycerin; esters of polyhydric alcohols such as glycerol mono-, di- or triacetate; and aliphatic esters of mono-, di- or polycarboxylic acids, such as dimethyl dodecanedioate and dimethyl tetradecanedioate. Particularly preferred aerosol formers are polyhydric alcohols or mixtures thereof, such as triethylene glycol, 1,3-butanediol and, most preferably, glycerin.
    [0029] The aerosol forming substrate may comprise other additives and ingredients, such as flavorings.
    [0030] Preferably, the aerosol forming substrate comprises nicotine and at least one aerosol former. In a particularly preferred embodiment, the aerosol former is glycerin.
    [0031] The container is preferably filled with between about 150 mg and about 400 mg of aerosol-forming substrate, more preferably between about 200 mg and about 300 mg of aerosol-forming substrate, and in a preferred embodiment , about 250 mg of aerosol forming substrate.
    [0032] In accordance with a further aspect of the present invention, there is provided a method of manufacturing a container comprising an aerosol generating substrate described herein.

    [0033] Preferably, the method further comprises the step of forming each strip with electrical resistance by at least one of: stamping; print; engraving; deposition with sintering; and deposition without sintering. In a particularly preferred embodiment, the electrically resistive bands are formed by stamping. Preferably, the tolerance of the dimensions of the electrical resistance strip is less than 1/10° mm, and preferably, the accuracy is at least 99%.
    [0034] Preferably, the method comprises applying the electrically resistive formed strip onto a substantially continuous web of flexible substrate material, the continuous web of substrate material being supplied on a spool, for use in forming lids for a container. By providing a substantially continuous weft spool of flexible substrate material, the heater forming process can be separated from the cap forming process, thus improving the efficiency of the manufacturing process.
    [0035] According to a further aspect of the present invention, an electrically heated aerosol generating device is provided. The device comprises: a power supply; a cavity for receiving a container as described herein containing an aerosol forming substrate; the electrical contacts connected to the power supply and configured to couple the power supply to the heater of a container through the electrical contacts of the container; and means for puncturing the puncturing area of a container when the container is received in the cavity.
    [0036] By providing an aerosol generating device, the heating efficiency of an aerosol generating substrate and hence the aerosol generating efficiency can be improved because the heater can be provided closer to the aerosol generating substrate.
    [0037] The piercing means is preferably a piercing element. The device preferably further comprises a mouthpiece. The mouthpiece comprises: the piercing element; at least one air inlet and at least one air outlet, wherein the piercing element comprises at least a first conduit extending between at least one air inlet and a distal end of the piercing element and at least one second conduit that extends between a distal end of the piercing element and at least one air outlet so that in use, when the user breathes in through the mouthpiece, air flows to the along the airflow path extending from at least one air inlet, through at least one first conduit, through a portion of the container, through at least one second conduit, and out of at least one exit.
    [0038] The piercing means may be an electrical insulator. As used here, "electrical insulator" is a material whose internal electric charges do not flow freely, and therefore very unlikely to conduct an electric current under the influence of an electric field. Preferably, the electrical insulator must have a resistivity of 1 x 104 Qm or more.
    [0039] Preferably, the electrical contacts are provided at a first and a second radial distance from the longitudinal axis of the device to ensure proper connection to the electrical contacts of the heater. In a preferred embodiment, the electrical contacts are substantially continuous rings, so that the container can be provided in the cavity in any axial rotation and still allow the proper electrical connections to be made. Preferably, the rings are concentric.
    [0040] In the embodiment comprising a mouthpiece having a piercing element, electrical contacts are provided on the device housing and on the mouthpiece. The electrical contacts on the nozzle are preferably rings and more preferably concentric rings. The electrical contacts in the housing are preferably provided at the first and second radial distance. Thus, the electrical contacts inside the mouthpiece are configured to couple the electrical contacts of the container to the electrical contacts of the device provided in the housing.
    [0041] The power supply can be a battery and can be a rechargeable battery set for many charge and discharge cycles. The battery may be a lithium-based battery, for example lithium-cobalt, lithium-iron-phosphate, lithium titanate, or a lithium polymer battery. Alternatively, the battery may be a nickel metal hydride battery or a nickel cadmium battery. Battery capacity is preferably selected to allow multiple uses by the user before recharging is required. Battery capacity is preferably sufficient for a minimum of 20 uses by the user before recharging is necessary.
    [0042] As an alternative, power supply can be another form of charge storage device, such as a capacitor. The power supply may require recharging and may have a capacity that allows sufficient energy storage for one or more smoking experiences; for example, the power supply may have sufficient capacity to allow continuous aerosol generation for a period of about six minutes, corresponding to the typical time taken to smoke a conventional cigarette, or for a period that is a multiple of six minutes. In another example, the power supply may have sufficient capacity to allow a predetermined number of puffs or discrete activations of the heater assembly.
    [0043] The aerosol generating device further comprises, preferably, electronic control components. The control electronics are preferably configured to supply and regulate power from the power supply to at least one heater. Power can be supplied to the heater assembly continuously after system activation, or it can be supplied intermittently, such as on a puff basis.

    [0044] Control electronics may include a microprocessor, which may be a programmable microprocessor. Control electronics may comprise other electronics.
    [0045] The control electronics are further configured, preferably, to maintain the temperature of the at least heater at an operating temperature of between about 80 degrees C to 270 degrees C. The operating temperature depends on the type of aerosol former , if any, used in the aerosol generating substrate. Preferably, when the aerosol former is propylene glycol, the operating temperature is preferably between about 80 degrees C and about 90 degrees C. Preferably, when the aerosol former is glycerin, the operating temperature is preferably at between about 120 degrees C and about 200 degrees C.
    [0046] In addition, control electronics can be configured to allow instantaneous heating of the aerosol generating substrate. Instant heating, as used herein, is defined as heating for less than about 3 seconds, more preferably, for less than 2 seconds. During flash heating, enough energy is transferred to the aerosol generating substrate to raise the temperature of the aerosol generating substrate by up to 350 degrees C to reach the volatilization temperature as quickly as possible.
    [0047] The aerosol generating device may further comprise a temperature sensor adjacent the cavity for receiving the container. The temperature sensor is in communication with the control electronics to allow the control electronics to maintain the temperature at operating temperature. The temperature sensor may be a thermocouple or alternatively at least one heater may be used to provide temperature related information. In this alternative, the temperature dependent resistive properties of the at least one heater are known and are used to determine the temperature of the at least one heater in a manner known to those skilled in the art.
    [0048] The aerosol generating device may comprise a puff detector in communication with the control electronics. The puff detector is preferably configured to detect when a user draws into the mouth of the aerosol generating device. The control electronics are preferably further configured to control power to at least one heating element dependent on the blow detector input.
    [0049] The aerosol generating device further preferably comprises a user input such as a switch or button. This allows the user to activate the device. The switch or button can initiate aerosol generation or prepare the control electronics to wait for the blow detector to enter.
    [0050] In use, the user inserts a container described in this document into the cavity of an aerosol generating device as described in this document. The user then attaches the mouthpiece to the main body of the aerosol generating device that pierces the capsule with the piercing part. The user then activates the device by pressing the button. The user then draws on the mouthpiece, drawing the air into the device through the air inlet, the air then passes through the container which draws the vaporized aerosol forming substrate into the air stream and exits the device through the air outlet in the mouthpiece, to be inhaled by the user.
    [0051] The aerosol generating device further comprises a housing comprising the cavity and other components. The housing of the aerosol generating device is preferably elongated, such as an elongated cylinder with a circular cross-section. The housing may comprise any suitable material or combination of materials. Examples of suitable materials include metals, alloys, plastics or composite materials that contain one or more of those materials, or thermoplastics that are suitable for pharmaceutical or food applications, for example, polypropylene, polyetheretherketone (PEEK) and polyethylene. Preferably, the material is light and not fragile.
    [0052] Preferably, the aerosol generating system is portable. The aerosol generating system may have a size comparable to a conventional cigar or cigarette. The smoking system may have an overall length of between about 30 mm and approximately 150 mm. The smoking system may have an outside diameter of between approximately 5 mm and approximately 30 mm.
    [0053] The aerosol generating device may further comprise a heater. The additional heater can be provided in the cavity to receive a container. The additional heater is configured to receive power from the power supply. The additional heater may allow the aerosol generating substrate to reach operating temperature more quickly.
    [0054] Any feature in one aspect of the invention may be applied to other aspects of the invention, in any appropriate combination. In particular, the method aspects can be applied to the apparatus aspects, and vice versa. Furthermore, any, some, and/or all of the features in one aspect may be applied to any, some, and/or all of the features in any other aspect, in any appropriate combination.
    [0055] It is also to be contemplated that specific combinations of the various features described and defined in any aspects of the invention may be implemented and/or provided and/or used independently.
    [0056] The invention will be described below, by way of example only, with reference to the accompanying drawings, in which:
    [0057] Figure 1 shows a lid comprising an electrical heater for a container in accordance with the present invention;
    [0058] Figure 2 shows a container according to the present invention comprising a lid, as shown in Figure 1;
    [0059] Figure 3 shows a further embodiment of a lid comprising an electrical heater for a container in accordance with the present invention;
    [0060] Figure 4 shows an aerosol generating device in accordance with the present invention, with and without a container, in accordance with the present invention; and
    [0061] Figures 5 show a method of manufacturing a container according to the present invention.
    [0062] Figure 1 shows a lid 100 for a container for use in an aerosol generating device. The cover 100 comprises a pierceable film 102 and an electrical heating element 104. The electrical heating element comprises two electrical contacts 106 and 108. The electrical contacts are provided at a first and a second radial distance from the center of the cover. . The electrical heating element 104 is arranged having a puncturing area A. Area A can be punctured without affecting the operation of the heating element.
    [0063] The electric heater is preferably formed of foil material for stamping, the material being preferably stainless steel, copper or bronze. The manufacturing process is described below in more detail.
    [0064] Figure 2 shows an exploded view of a container 200. The container comprises a housing 202 having a thin-walled outer wall and a thin-walled base. Cap 100 is provided at the open end of housing 202 to form the sealed container for use in an aerosol generating device. Before the cap is sealed to the housing flap 202, the container housing is filled with an aerosol-forming substrate (not shown). Approximately 250 mg of aerosol forming substrate is supplied into the container. The aerosol forming substrate comprises a nicotine-containing material such as tobacco and an aerosol former. The aerosol former is glycerin which provides a good mouthfeel to the user; Glycerin has also been found to produce an appropriately small aerosol droplet diameter compared to other aerosol formers.
    [0065] Figure 3 shows an alternative cap 300 for use in an aerosol generating device. The cover 300 again comprises a puncture film 302 and an electrical heating element 304. The electrical heating element comprises two electrical contacts 306 and 308. Again, the electrical contacts are provided at a first and a second radial distance from the cover center. The electrical heating element 304 is arranged having a puncturing area B. Area B can be punctured without affecting the operation of the heating element. The embodiment shown in Figure 3 allows a heating element to have a greater overall length than the embodiment shown in Figure 1.
    [0066] Figure 4(a) shows a cross-sectional view of an aerosol generating device 400 for use with a container 200 described above. The aerosol generating device comprises an outer housing 402 adapted to house: a power supply 404 such as a rechargeable battery; and control circuit 406. Housing 302 further comprises a cavity 408 configured to receive a container 200. Aerosol generating device 400 further comprises a nozzle 412 attachable to a proximal end of the aerosol generating device housing 402. The nozzle comprises a piercing part 414 and two airflow conduits, an inlet conduit 416 and an outlet conduit 418. The nozzle further comprises electrical contacts 420, in the form of concentric rings, which are described in more detail below.
    [0067] Figure 4(b) shows a cross-sectional view of an aerosol generating device 400 comprising a container 200. The container is received in the cavity of the housing. The electrical contacts of the container lid 200 connect to the electrical contacts of the mouthpiece when the mouthpiece is coupled to the housing 402. The electrical contacts of the mouthpiece further connect to the electrical contacts within the aerosol generating device, which are coupled to the control circuit 406.
    [0068] In use, the user inserts the container 200 into the cavity of the aerosol generating device 400 and then couples the mouthpiece 412 to the housing 402. Upon coupling the mouthpiece, the piercing portion 414 pierces the lid of the container and forms a airflow route from the air inlet, through the container to the air outlet. By doing this, electrical connections are also made. The user then presses a button (not shown) to activate the device. To activate the device, the heater is powered by the control electronics 406 from the power supply 404. When the capsule temperature reaches the operating temperature of between about 220°C and about 240°C, the user is informed by means of an indicator (not shown) which the user can then swallow through the mouthpiece. When the user inhales through the mouthpiece, air enters the air inlet, proceeds through conduit 416 into the mouthpiece and capsule, drags the vaporized aerosol-forming substrate, and then exits the capsule through outlet conduit 318 into the mouthpiece. .
    [0069] The container shell can be manufactured using suitable known techniques such as drawing and therefore will not be described in detail in this document. However, the manufacturing process of the heating element and lid is described with reference to Figures 5.
    [0070] Figure 5(a) shows a coil 500 comprising a web of flexible substrate material. The flexible substrate material is configured to receive a pre-embossed heating element 502. The heating element may be embossed using a suitable die and stamper assembly. Therefore, in the process step shown in Figure 5(a), a substantially continuous web of flexible substrate material having various heating elements is formed.
    [0071] Figure 5(b) shows the next step in the process. The web of flexible substrate material is cut, using a stamper 504 and die, into individual disks 506 each having a heating element. The discs have a diameter substantially equal to the diameter of the cap.
    [0072] Figure 5(c) shows the individual discs 506 being applied to a substantially continuous web of puncture film 508, such as aluminum. Discs can be applied using adhesive (not shown) or any other suitable attachment means to secure the disc to the film.
    [0073] The covers 100 are then formed using an additional stamper 510 and die, as shown in Figure 5(d). The preformed shell of the container is then filled with the aerosol forming substrate 512 using the nozzle 514, as seen in Figure 5(e). As shown in Figure 5(f), the cap 100 is finally sealed to the edge of the container using the applicator 516 to form a sealed container for use in the aerosol generating device as described above.
    [0074] Other container designs that incorporate a heater, in accordance with this description, can now be devised by a person skilled in the art.
    [0075] The examples of the modalities described above illustrate, but are not limiting. In view of the exemplary embodiments discussed above, other embodiments consistent with the above exemplary embodiments will now be apparent to those skilled in the art.
