Definitions
- the present invention relates to a smoking substitute system and particularly, although not exclusively, to a smoking substitute system having a device with engagable housing portions.
- the smoking of tobacco is generally considered to expose a smoker to potentially harmful substances. It is generally thought that a significant amount of the potentially harmful substances are generated through the heat caused by the burning and/or combustion of the tobacco and the constituents of the burnt tobacco in the tobacco smoke itself.
- Conventional combustible smoking articles such as cigarettes, typically comprise a cylindrical rod of tobacco comprising shreds of tobacco which is surrounded by a wrapper, and usually also a cylindrical filter axially aligned in an abutting relationship with the wrapped tobacco rod.
- the filter typically comprises a filtration material which is circumscribed by a plug wrap.
- the wrapped tobacco rod and the filter are joined together by a wrapped band of tipping paper that circumscribes the entire length of the filter and an adjacent portion of the wrapped tobacco rod.
- a conventional cigarette of this type is used by lighting the end opposite to the filter, and burning the tobacco rod. The smoker receives mainstream smoke into their mouth by drawing on the mouth end or filter end of the cigarette.
- Such smoking substitute systems can form part of nicotine replacement therapies aimed at people who wish to stop smoking and overcome a dependence on nicotine.
- Smoking substitute systems include electronic systems that permit a user to simulate the act of smoking by producing an aerosol (also referred to as a "vapour") that is drawn into the lungs through the mouth (inhaled) and then exhaled.
- aerosol also referred to as a "vapour”
- the inhaled aerosol typically bears nicotine and/or flavourings without, or with fewer of, the odour and health risks associated with traditional smoking.
- smoking substitute systems are intended to provide a substitute for the rituals of smoking, whilst providing the user with a similar experience and satisfaction to those experienced with traditional smoking and with combustible tobacco products.
- Some smoking substitute systems use smoking substitute articles (also referred to as a "consumables”) that are designed to resemble a traditional cigarette and are cylindrical in form with a mouthpiece at one end.
- HT Heated Tobacco
- HNB Heat not burn
- the tobacco may be leaf tobacco or reconstituted tobacco.
- the vapour may contain nicotine and/or flavourings.
- the intention is that the tobacco is heated but not burned, i.e. the tobacco does not undergo combustion.
- a typical HT smoking substitute system may include a device and a consumable.
- the consumable may include the tobacco material.
- the device and consumable may be configured to be physically coupled together.
- heat may be imparted to the tobacco material by a heating element of the device, wherein airflow through the tobacco material causes components in the tobacco material to be released as vapour.
- a vapour may also be formed from a carrier in the tobacco material (this carrier may for example include propylene glycol and/or vegetable glycerine) and additionally volatile compounds released from the tobacco.
- the released vapour may be entrained in the airflow drawn through the tobacco.
- the vapour passes through the consumable (entrained in the airflow) from the location of vapourisation to an outlet of the consumable (e.g. a mouthpiece), the vapour cools and condenses to form an aerosol for inhalation by the user.
- the aerosol will normally contain the volatile compounds.
- HT smoking substitute systems heating as opposed to burning the tobacco material is believed to cause fewer, or smaller quantities, of the more harmful compounds ordinarily produced during smoking. Consequently, the HT approach may reduce the odour and/or health risks that can arise through the burning, combustion and pyrolytic degradation of tobacco.
- Some systems include a device with a cap that is engagable with a body of the device.
- the cap may be engaged with the body by a snap engagement mechanism.
- snap engagement mechanisms can, in some cases, provide a connection that does not provide sufficient retention between the body and cap.
- the present invention relates to a smoking substitute device including a first housing portion engageable with a second housing portion, and a reinforcement element mountable to the second housing portion for resisting disengagement of the first and second housing portions.
- a smoking substitute device comprising a first housing portion, a second housing portion configured for snap engagement with the first housing portion when moved towards one another along an engagement axis, the second housing portion comprising: an elongate engagement member having a hook portion at a distal end thereof, the elongate member configured to flex from an engaged position in which the hook portion engages the first housing portion to a disengaged position in which the hook portion is deflected away from the engagement axis, and a reinforcement element mountable to the second housing portion and configured to resist flexing of the elongate member away from the engagement axis.
- a reinforcement element increases the external force required to disengage the first housing portion from the second housing portion. This may help to prevent the involuntarily disengagement of the first housing portion from the second housing portion. Further, the provision of a separate reinforcement element may allow differences in material between the engagement member and the reinforcement element. The reinforcement element may thus be formed of material that has greater durability (e.g. under conditions in which components may be susceptible to heat damage).
- the elongate engagement member may extend substantially parallel to the engagement axis.
- the reinforcement element may be configured to resist movement of the engagement member (i.e. the hook portion) in a direction that is generally perpendicular (i.e. lateral) to the engagement axis. Movement of the engagement member away from the engagement axis may result in disengagement of the first housing portion from the second housing portion. Thus, the reinforcement element may increase the force required to disengage the first housing portion from the second housing portion.
- the reinforcement element may engage an outwardly facing surface of the elongate member so as to resist movement of the engagement member in the lateral direction.

- the edge may be an edge of an aperture or recess formed in the first housing portion. Alternatively, the edge may form part of a ledge or lip of the first housing portion.
- the hook portion may comprise an engagement surface that abuts the edge when engaged.
- the engagement surface and edge may be oriented so as to be generally perpendicular to the engagement axis. In this way, when the engagement surface abuts the edge, movement of the first and second housing portions away from each other (e.g. along the engagement axis) is restricted.
- the engagement surface may define an in use lower surface of the hook portion.
- the hook portion may be received in an aperture or recess of the first housing portion.
- the aperture of recess may be elongate (e.g. in the direction of the engagement axis) so as to allow the hook portion to slide within the aperture or recess.

- the hook portion may snap into and engage with a recess, aperture or ledge of the first housing.
- the second housing portion may comprise a further engagement member (i.e. so as to have two engagement members) spaced from and opposing one another. Both of the engagement members may be as described above.
- the engagement members may be arranged such that their hook portions are directed towards one another.
- the engagement members may both be spaced laterally from the engagement axis.
- the members may be arranged about the engagement axis so as to be diametrically opposite one another with respect to the engagement axis.
- the reinforcement element may be configured to resist movement of the engagement members away from the engagement axis.
- the reinforcement element may engage respective outwardly facing (i.e. outer) surfaces of the engagement members (so as to resist movement of each engagement member away from the engagement axis).

- the opening 221 and the cavity 222 are formed so as to receive at least a portion of the consumable 202.
- a portion of the consumable 202 is received through the opening 221 and into the cavity 222.
- the downstream end 218 of the consumable 202 protrudes from the opening 221 and thus protrudes also from the device 201.
- the opening 221 includes laterally disposed notches 226. When a consumable 202 is received in the opening 221, these notches 226 remain open and could, for example, be used for retaining a cover to cover the end of the device 201.
- Figure 2E shows a cross section through a central longitudinal plane through the device 201.
- the device 201 is shown with the consumable 202 engaged therewith.
- the device 201 comprises a heater 204 comprising heating element 223.
- the heater 204 forms part of the body 209 of the device 201 and is rigidly mounted to the body 209.
- the heater 204 is a rod heater with a heating element 223 having a circular transverse profile.
- the heater may be in the form of a blade heater (e.g. heating element with a rectangular transverse profile) or a tube heater (e.g. heating element with a tubular form).
- the heating element 223 of the heater 204 projects from an internal base of the cavity 222 along a longitudinal axis towards the opening 221. As is apparent from the figure, the length (i.e. along the longitudinal axis) of the heating element is less than a depth of the cavity 222. In this way, the heating element 223 does not protrude from or extend beyond the opening 221.
- the heating element 223 penetrates the aerosol-forming substrate 213 of the consumable 202.
- the heating element 223 extends for nearly the entire axial length of the aerosol-forming substrate 213 when inserted therein.
- the heater 204 is activated, heat is transferred radially from an outer circumferential surface the heating element 223 to the aerosol-forming substrate 213.
- the cap 210 is configured for engagement with the body 209.

- the body 209 comprises two opposing elongate engagement members 250 that extend longitudinally and parallel to the engagement axis (i.e. so as to be parallel to the heating element 223).
- the engagement members 250 each comprise a flexible arm 251 and an inwardly protruding hook portion 232 disposed at a distal end of the flexible arm 251.
- Each hook portion 232 comprises an engagement surface 233 (defining an underside of the hook portion 232) and an opposing ramp surface 234 (which defines a distal leading surface of the hook portion 232).
- the elongate engagement members 250 are configured to flex such that their respective hook portions 232 move laterally (with respect to the engagement axis) between an engaged position and a disengaged position.
- the hook portions 232 each define a free end of their respective engagement member 250.
- Each engagement member 250, at an opposing end, is integrally formed with the body 209 such that the engagement members 250 are formed of the same material as the body 209 (which may be e.g. a plastic material).
- the body 209 comprises a guide structure 235, which is generally tubular and defines an elongate cavity. This elongate cavity receives a portion of the cap 210 when the body 209 and cap 210 are engaged.
- the guide structure 235 comprises opposing elongate longitudinal slots 236. Each engagement member 250 extends longitudinally within a respective slot 236. In this way, the hook portions 232 project inwardly into the cavity defined by the guide structure 235.
- the hook portions 232 are moved outwards by contact of a leading edge of the cap 210 with the ramp surfaces 234, and then the hook portions 232 subsequently snap into longitudinally extending apertures formed in the cap 210.
- the elongate nature of these apertures allows the cap 210 to move longitudinally with respect to the body 209 (whilst engaged).
- the cap 210 is shown in a retracted position in which it is fully received in the cavity of the guide structure 235.
- the cap 210 is shown in an extended position in which the cap 210 has been slid in a longitudinal direction away from the body 209.
- engagement surfaces 233 of the hook portions 232 abut (i.e. so as to engage with) respective lower edges 237 of the apertures formed in cap 210.
- This interaction between the lower edges 237 and the engagement surfaces 233 prevents further movement of the cap 210 away from the body 209.
- the cap 210 may be partially retained in the retracted and extended positions by bump features (e.g. protrusions interacting with the hook portions 232) formed in the side edges 230 of the apertures formed in the cap 210.
- the cap 210 can only be disengaged from the body 209 by moving the hook portions 232 outwardly.
- the body 209 further comprises a reinforcement element 240.
- This reinforcement element 240 is shown in isolation in Figure 2I .
- the reinforcement element 240 comprises opposing curved arms 238 so as to be generally C-shaped.
- a distal end of each arm 238 comprises an outwardly extending lip 239 (i.e. extending away from the opposing arm 238).
- the reinforcement element 240 is pushed onto the guide structure 235 so as to wrap around the guide structure 235.
- the lips 239 of the reinforcement element 240 facilitate receipt of the guide structure 235 between the arms 238.
- the reinforcement element 240 is formed of a flexible metallic material (such as spring steel).
- each of the arms 238 of the reinforcement element 240 engages an outwardly facing surface of a respective one of the engagement member 250.
- Each engagement member 250 comprises a recess 241 (see Figure 2J ) to accommodate this engagement.
- the engagement member 250 resists lateral movement of the hook portions 232 away from the engagement axis (i.e. and out of the apertures of the cap 210). In this way, the force to disengage the cap 210 from the body 209 is increased by the reinforcement element 240.
- the presence of the reinforcement element 250 may increase the disengagement force from approximately 60 N to 100 N.
- the device 202 further comprises an electronics cavity 224.
- a power source in the form of a rechargeable battery 205 (a lithium ion battery), is located in electronics cavity 224.
- the device 202 includes a connector (i.e. forming part of an IO module of the device 201) in the form of a USB port 206.
- the connector may alternatively be, for example, a micro-USB port or a USB-C port for examples.
- the USB port 206 may be used to recharge the rechargeable battery 205.

- the controller 208 is configured to control the operation of the heater 204.
- Such control of the operation of the heater 204 may be accomplished by the controller toggling the electrical connection of the rechargeable battery 205 to the heater 204.
- the controller 208 is configured to control the heater 204 in response to the user depressing the button 212. Depressing the button 212 may cause the controller to allow a voltage (from the rechargeable battery 205) to be applied to the heater 204 (so as to cause the heating element 223 to be heated).
- the controller is also configured to control the LEDs 211 in response to (e.g. a detected) a condition of the device 201 or the consumable 202.
- the controller may control the LEDs to indicate whether the device 201 is in an on state or an off state (e.g. one or more of the LEDs may be illuminated by the controller when the device is in an on state).
- the device 202 comprises a further input means (i.e. in addition to the button 212) in the form of a puff sensor 225.
- the puff sensor 225 is configured to detect a user drawing (i.e. inhaling) at the downstream end 218 of the consumable 202.
- the puff sensor 225 may, for example, be in the form of a pressure sensor, flowmeter or a microphone.
- the puff sensor 225 is operatively connected to the controller 208 in the electronics cavity 224, such that a signal from the puff sensor 225, indicative of a puff state (i.e. drawing or not drawing), forms an input to the controller 208 (and can thus be responded to by the controller 208).

- the consumable 302 includes a tank 327.
- the tank 327 defines a reservoir for the storage of an aerosol-former, which in this embodiment, is in the form of e-liquid.
- the consumable 302 is a "single-use" consumable. That is, upon exhausting the e-liquid in the tank 327, the intention is that the user disposes of the whole consumable 302.
- the e-liquid i.e. aerosol former
- the tank may be refillable with e-liquid or the e-liquid may be stored in a non-consumable component of the system.
- the e-liquid may be stored in a tank located in the device or stored in another component that is itself not single-use (e.g. a refillable cartomizer).
- a heater 304 is located in the consumable 302 and is configured to heat and vaporise the e-liquid (stored in the tank 327).
- the heater 304 comprises a porous wick and a resistive heating element.
- the porous wick conveys e-liquid from the tank 327 to the heating element.
- the heating element is a heating filament that is helically wound around a portion of the porous wick, such that when the heating element is heated (e.g. by the action of electrical current passing through the heating element), heat is transferred from the heating element to the e-liquid conveyed by the wick.
- This transfer of heat vaporises the e-liquid and the resultant vapour is entrained in an airflow passing through the consumable 302 (i.e. driven by a user drawing on a downstream end 318 of the consumable 302). Between the vaporisation point at the coil and the downstream end 318 (i.e. the mouth end), the vapour condenses into an aerosol, and is subsequently inhaled by the user.

- the heater electrical contacts 328 are brought into electrical contact with corresponding device electrical contacts (not shown) on the device 301.
- the device electrical contacts are electrically connected (directly or indirectly) to the rechargeable battery.
- the controller may thus be configured to control the voltage applied across the device electrical contacts from the rechargeable battery. By controlling the voltage applied across the device electrical contacts, the voltage applied to the heater 304 is correspondingly controlled.
- the device 302 includes an output means (forming part of the UI of the system 300) in the form of a single light-emitting diode ("LED") 311.
- the LED 311 is operatively connected to the controller, such that controller can control the illumination of the LED 311.
