Definitions

  • the present invention relates to an aerosol delivery device and system, and particularly, although not exclusively, to an aerosol delivery device/system including an aerosol generator in the form of a porous element.
  • an aerosol delivery device is a smoking-substitute system, which is an electronic system that permits the user to simulate the act of smoking by producing an aerosol or vapour that is drawn into the lungs through the mouth and then exhaled.
  • the inhaled aerosol or vapour typically bears nicotine and/or other flavourings without the odour and health risks associated with traditional smoking and tobacco products.
  • the user experiences a similar satisfaction and physical sensation to those experienced from a traditional smoking or tobacco product, and exhales an aerosol or vapour of similar appearance to the smoke exhaled when using such traditional smoking or tobacco products.
  • a smoking substitute system is the so-called “vaping” approach, in which a vaporisable liquid, typically referred to (and referred to herein) as “e-liquid", is heated by a heating element to produce an aerosol/vapour which is inhaled by a user.
  • the e-liquid typically includes a base liquid as well as nicotine and/or flavourings.
  • the resulting vapour therefore also typically contains nicotine and/or flavourings.
  • the base liquid may include propylene glycol and/or vegetable glycerine.
  • a typical vaping smoking substitute system includes a mouthpiece, a power source (typically a battery), a tank for containing e-liquid, as well as a heating element.
  • a power source typically a battery
  • a tank for containing e-liquid as well as a heating element.
  • electrical energy is supplied from the power source to the heating element, which heats the e-liquid to produce an aerosol (or "vapour") which is inhaled by a user through the mouthpiece.
  • Vaping smoking substitute systems can be configured in a variety of ways.
  • there are "closed system" vaping smoking substitute systems which typically have a sealed tank and heating element. The tank is pre-filled with e-liquid and is not intended to be refilled by an end user.
  • One subset of closed system vaping smoking substitute systems include a base unit which includes the power source, wherein the base unit is configured to be physically and electrically coupled to a consumable including the tank and the heating element.
  • the consumable may also be referred to as a cartomizer. In this way, when the tank of a consumable has been emptied, the consumable is disposed of. The base unit can be reused by connecting it to a new, replacement, consumable.
  • Another subset of closed system vaping smoking substitute systems are completely disposable, and intended for one-use only.
  • vaping smoking substitute systems which typically have a tank that is configured to be refilled by a user. In this way the system can be used multiple times.
  • An example vaping smoking substitute system is the myblu® e-cigarette.
  • the myblu® e-cigarette is a closed system which includes a base unit and a consumable.
  • the base unit and consumable are physically and electrically coupled together by pushing the consumable into the base unit.
  • the base unit includes a rechargeable battery.
  • the consumable includes a mouthpiece, a sealed tank which contains e-liquid, as well as a heating element, which for this system is a heating filament coiled around a portion of a wick.
  • the wick is partially immersed in the e-liquid, and conveys e-liquid from the tank to the heating filament.
  • the device is activated when a microprocessor on board the base unit detects a user inhaling through the mouthpiece. When the system is activated, electrical energy is supplied from the power source to the heating element, which heats e-liquid from the tank to produce a vapour which is inhaled by a user through the mouthpiece.
  • a smoking substitute device it is desirable to deliver nicotine into the user's lungs, where it can be absorbed into the bloodstream.
  • e-liquid is heated by a heating element to produce an aerosol/vapour which is inhaled by a user.
  • Many e-cigarettes also deliver flavour to the user, to enhance the experience.
  • Flavour compounds are contained in the e-liquid that is heated. Heating of the flavour compounds may be undesirable as the flavour compounds are inhaled into the user's lungs.
  • Toxicology restrictions are placed on the amount of flavour that can be contained in the e-liquid. This can result in some e-liquid flavours delivering a weak and underwhelming taste sensation to consumers in the pursuit of safety.
  • liquid used to form an aerosol can leak from the device and/or can collect in or on parts of the device.
  • liquid can be entrained in an airflow in the airflow path.
  • the present invention has been devised in light of the above considerations.
  • the present invention relates to an aerosol delivery device comprising an aerosolisation chamber having a uniform/constant cross-sectional area along its length, and a porous liquid transfer element at least partly received in the aerosolisation chamber.
  • an aerosol delivery device comprising:
  • an aerosolisation chamber having a uniform cross-sectional area may reduce or avoid the build-up of aerosol precursor at the mouthpiece aperture.
  • a conical chamber can diverge from the aerosol generating portion of the liquid transfer element, which may result in a space between the wall(s) defining the chamber and the liquid transfer element that is larger than would otherwise be the case of a non-diverging (i.e. uniform cross-section) chamber.
  • This larger space may allow for a greater build-up of aerosol precursory, so as to result in a larger propensity for leakage from the device and may also result in a greater propensity for large droplets of aerosol precursor to be entrained in airflow from the device.
  • the provision of a uniform cross-section chamber may result in a more consistent droplet size in the aerosol delivered by the device.
  • the surface tension of any aerosol precursor between the chamber walls and the aerosol generating portion may be more likely to be sufficient to retain the aerosol precursor in the device.
  • the aerosolisation chamber extends from the mouthpiece aperture, it may otherwise be considered an outlet (e.g. a mouthpiece outlet) of the device.
  • the aerosol generating portion of the liquid transfer element may have a larger transverse cross-sectional area (taken at a location adjacent the conveying portion) than a transverse cross-sectional area (taken at a location adjacent the aerosol generating portion) of the conveying portion.
  • the aerosol generating portion may define an enlarged portion of the aerosol generator.
  • the aerosol generating portion may have a circular transverse cross-sectional shape.
  • the conveying portion may have a circular transverse cross-sectional shape.
  • the aerosol generating portion may have a larger radius than the conveying portion.
  • a transversely (e.g. radially) extending transition surface may be defined between the conveying portion and the aerosol generating portion.
  • the transition surface may define an outward step from the conveying portion to the aerosol generating portion.
  • the transition surface may have a concave profile.
  • the transition surface may form a smooth continuous transition with an outer circumferential surface of the conveying portion.
  • there may be a (substantially) sharp transition between the transition surface and an outer circumferential surface of the aerosol generating portion.
  • a leading edge of the aerosol generating portion may be defined between the transition surface and the outer circumferential surface of the aerosol generating portion.
  • the aerosolisation chamber may have a cylindrical shape.
  • the aerosolisation chamber may have a circular cylinder shape (i.e. having a circular transverse cross-section) or an elliptical cylinder shape (having an elliptical transverse cross-section).
  • a transverse cross-sectional shape of the aerosol generating portion may correspond to a transverse cross-sectional shape of the aerosolisation chamber (i.e. they may both be circular or elliptical). In this way, the aerosol generating portion and a wall defining the aerosolisation chamber may be concentrically arranged.
  • the longitudinal length of the aerosolisation chamber may be between 6 mm and 3 mm, for example between 5 mm and 4 mm, e.g. about 4.5 mm.
  • the aerosol generating portion may be fully received in the aerosolisation chamber.
  • a portion of the conveying portion i.e. a portion adjacent the aerosol generating portion
  • only a portion of the aerosol generating portion (or liquid transfer element) may be received in the aerosolisation chamber (i.e. at an upstream end of the aerosolisation chamber).
  • a portion of the aerosolisation chamber e.g. at or adjacent to the mouthpiece aperture and downstream of the aerosol generating portion
  • An airflow path may be defined between a wall defining the aerosolisation chamber and the liquid transfer element. Where the aerosolisation chamber is cylindrical, the airflow path may be annular. The airflow path may have a constricted region defined by the aerosol generating portion. The transverse/radial distance between the aerosol generating portion and the wall of the aerosolisation chamber at the constricted region may be less than 0.5 mm, for example less than 0.4 mm, or e.g. less than 0.3 mm.
  • the constricted region may define the narrowest part of the airflow path through the aerosolisation chamber. This constriction of the airflow passage increases the velocity of air/vapour passing through the aerosolisation chamber.
  • the constriction may be referred to as a Venturi aperture.
  • the constriction may have a toroidal shape (i.e. extending about the aerosol generating portion of the liquid transfer element).
  • the toroidal shape may, however, be interrupted by supports (e.g. projections, ribs, etc.) protruding inwardly from wall(s) of the aerosolisation chamber to support the aerosol generating portion in the aerosolisation chamber.
  • the constriction reduces the air pressure of the airflow flowing through the constriction (i.e. in the vicinity of the aerosol generating portion). This low pressure and high velocity facilitate the generation of an aerosol from the aerosol precursor held in the aerosol generating portion (i.e. conveyed from the storage chamber by the liquid transfer element). This aerosol is entrained in the airflow passing through the constriction and is discharged from the mouthpiece aperture of the aerosol delivery device.
  • the airflow path may have an expansion region downstream of the constricted region, in which a cross-sectional area of the airflow path (e.g. gradually) increases in the downstream direction.
  • the expansion region may be defined by a tapered section of the aerosol generating portion.
  • the tapered section may taper inwardly in a direction from the constricted region to a downstream (distal) end of the aerosol generating portion.
  • the taper may have a curved profile (i.e. in the longitudinal direction).
  • upstream and downstream are used herein with reference to the direction of airflow through the device during normal use of the device (i.e. by way of inhalation at the mouthpiece aperture).
  • the transverse/radial distance between the aerosol generating portion and the wall of the aerosolisation chamber at the distal/downstream end of the aerosol generating portion may be less than 1 mm, for example less than 0.7 mm, or e.g. less than 0.5 mm.
  • the transverse/radial distance between the aerosol generating portion and the wall of the aerosolisation chamber at the distal/downstream end of the aerosol generating portion may be less than 20% of the diameter of aerosolisation chamber, for example less than 17%, or e.g. less than 15%.
  • a distal (transversely extending) end surface of the aerosol generating portion may be being substantially planar.
  • the aerosol generating portion and thus the liquid transfer element
  • the aerosol generating portion may have a flattened or truncated distal end.
  • the combination of the planar/flattened distal end and the aerosolisation chamber of constant cross-sectional area may provide a more evenly dispersed spray from the device.
  • such an arrangement may result in a smaller gap between the aerosolisation chamber walls and the aerosol generating portion (e.g. compared with an arrangement having a conical outlet and/or a conical aerosol generating portion), which may reduce the presence of large droplets of liquid in the aerosol discharged from the device.
  • the distal end of the aerosol generating portion may be spaced from the mouthpiece aperture/end surface (e.g. transversely extending end surface of the mouthpiece) in an upstream longitudinal direction. That is, the distal (downstream) end of the aerosol generating portion/liquid transfer element may be recessed with respect to the end surface of the mouthpiece.
  • the distal end may be spaced (in the longitudinal direction) from the end surface of the mouthpiece or mouthpiece aperture by less than 1.5 mm, or less than 1 mm, or e.g. less than 0.5 mm.
  • the aerosolisation chamber may be defined by a tube extending upstream and longitudinally from the end surface of the mouthpiece.
  • the device may comprise a retaining element for retaining the liquid transfer element in position with respect to the mouthpiece.
  • the retaining element may comprise a mounting portion extending about the tube so as to mount the retaining element to the tube.
  • the retaining element may comprise a collar projecting from the mounting portion and at least partly circumscribing the liquid transfer element (e.g. the conveying portion) so as to retain the liquid transfer element against movement relative to the mouthpiece.
  • the liquid transfer element (e.g. the conveying portion) may comprise one or more recesses for receipt of a portion of the collar so as to facilitate retaining of the liquid transfer element by the collar.
  • the aerosol delivery device may comprise a flow passage for fluid flow therethrough.
  • the flow passage may extend generally in the longitudinal direction between (and may fluidly connect) an inlet of the aerosol delivery device and the aerosolisation chamber.
  • a user may draw fluid (e.g. air) into and through the flow passage and aerosolisation chamber of the aerosol delivery device by inhaling at the mouthpiece aperture.
  • the flow passage may comprise one or more deflections. It may comprise a transverse portion proximal the inlet such that there is a deflection between inlet and the transverse portion of the flow passage.
  • the flow passage may then comprise a generally longitudinal portion downstream of the transverse portion.
  • the longitudinal portion may extend within a spacing between a device housing (which may be integral with the mouthpiece) and a tank (discussed further below) defining the storage chamber.
  • the flow passage may then deflect again (e.g. radially) at the upper surface of the tank within the mouthpiece, through the aerosolisation chamber, towards the mouthpiece aperture.
  • the flow passage may be a single (annular) flow passage around the tank or it may comprise two branches which split around the tank and re-join within the mouthpiece e.g. proximal the liquid transfer element.

  • a porous body may be disposed within the storage chamber, which may contain the aerosol precursor.
  • the tank may at least partially define the flow passage.

  • the liquid transfer element i.e. the aerosol generating portion
  • the liquid transfer element may do this in such a way that does not use heat to form the aerosol, and therefore in some embodiments may be referred to as a "passive" aerosol generator.
  • the conveying portion may be elongate and generally cylindrical, and may be at least partially enclosed within one or more internal walls of the aerosol delivery device.
  • the one or more internal walls enclosing the conveying portion may form part of the tank defining the storage chamber.
  • the tank may at least partly surround (e.g. may fully surround) the conveying portion. That is, the tank may define a conduit through which the conveying portion passes.
  • the conveying portion may extend generally longitudinally (e.g. centrally) through a portion of the tank (i.e. through the conduit defined by the tank).
  • the liquid transfer element (i.e. conveying portion) may extend into the storage chamber so as to be in contact with (e.g. at least partially submerged in) the aerosol precursor.
  • the liquid transfer element may be configured to convey the aerosol precursor from the storage chamber to the aerosolisation chamber via a wicking/capillary action.
  • the aerosol may be sized to inhibit pulmonary penetration.
  • the aerosol may be formed of particles with a mass median aerodynamic diameter that is greater than or equal to 15 microns, e.g. greater than 30 microns, or greater than 50 microns, or may be greater than 60 microns, or may be greater than 70 microns.
  • the aerosol may be sized for transmission within at least one of a mammalian oral cavity and a mammalian nasal cavity.
  • the first aerosol may be formed by particles having a maximum mass median aerodynamic diameter that is less than 300 microns, or e.g. less than 200 microns, or less than 100 microns. Such a range of mass median aerodynamic diameter can produce aerosols which are sufficiently small to be entrained in an airflow caused by a user drawing air through the aerosol delivery device and to enter and extend through the oral and or nasal cavity to activate the taste and/or olfactory receptors.
  • the size of aerosol formed without heating may be typically smaller than that formed by condensation of a vapour.
  • the mass median aerodynamic diameter is a statistical measurement of the size of the particles/droplets in an aerosol. That is, the mass median aerodynamic diameter quantifies the size of the droplets that together form the aerosol.
  • the mass median aerodynamic diameter may be defined as the diameter at which 50% of the particles/droplets by mass in the aerosol are larger than the mass median aerodynamic diameter and 50% of the particles/droplets by mass in the aerosol are smaller than the mass median aerodynamic diameter.
  • size of the aerosol refers to the size of the particles/droplets that are comprised in the particular aerosol.
  • the above configuration of the aerosol delivery device may be representative of an activated state of the aerosol delivery device.
  • the aerosol delivery device may additionally be configurable in a deactivated state.
  • the liquid transfer element may be isolated from the aerosol precursor.

  • the liquid transfer element 315 comprises a conveying portion 317 and an aerosol generating portion 322, which is located in aerosolisation chamber 319.
  • the aerosol generating portion 322 is a porous nib.
  • a storage chamber 316 (defined by a tank 318) for storing a first aerosol precursor (i.e. a liquid comprising a flavourant) is fluidly connected to the liquid transfer element 315.

  • the aerosol generating portion 322 is wider (has a greater radius) than the conveying portion 317.

  • the liquid transfer element 315 and the conduit 324 are located in a substantially central position within the storage chamber 316 and are substantially parallel to a central longitudinal axis of the consumable 303.
  • the porous nature of the liquid transfer element 315 means that first (flavoured) aerosol precursor in the storage chamber 316 is drawn into the liquid transfer element 315. As the flavoured aerosol precursor in the liquid transfer element 315 is depleted in use, further flavoured aerosol precursor is drawn from the storage chamber 316 into the liquid transfer element 315 via a wicking action.
  • the storage chamber 316 is fluidly isolated from the liquid transfer element 315.
  • the isolation is achieved via a plug 320 (preferably formed from silicone) located at one end of a conduit 324 surrounding the liquid transfer element 315.
  • the plug may be replaced by any one of: a duck bill valve; a split valve or diaphragm; or a sheet of foil.
  • the storage chamber 316 further includes an air bleed channel 332, which in the deactivated state is sealed by a sealing element comprising a pierceable membrane (preferably made from foil).
  • Activation (or piercing) member 330 which projects inwardly from the mouthpiece 309, and may take the form of a blade, pierces the pierceable membrane and opens the air bleed channel 332 when the consumable is moved to the activated state (as is discussed in more detail below).
  • the liquid transfer element 315 (i.e. the aerosol generating portion 322) is located within the aerosolisation chamber 319, such that an airflow path is defined between the liquid transfer element 315 an inner surface of the tube 337 defining the aerosolisation chamber 319.
  • This airflow path comprises a constricted region which is defined by the aerosol generating portion 322. This constriction results in increased air velocity and a corresponding reduction in air pressure of the air flowing along the airflow path and thus the constricted region may be referred to as a Venturi aperture.
  • one or more supports may extend inwardly from the wall defining the aerosolisation chamber 319 (e.g. tube 337) to contact the aerosol generating portion 322 and to support the aerosol generating portion 322 within the aerosolisation chamber 319.
  • the cartomizer portion 301 of the consumable 303 includes a reservoir 305 (defined by a container) for storing a second (e-liquid) aerosol precursor (which may contain nicotine).

  • the base unit includes an electrical power source, for example a battery.
  • Figure 3B shows the consumable 303 of Figure 3A in an activated state.
  • mouthpiece 309 is moved along a central longitudinal axis 350 in an upstream direction towards cartomizer portion 301.
  • the mouthpiece 309 is fixed by a collar 308 to the conveying portion 317 of the liquid transfer element 315 and therefore liquid transfer element 315 moves with the mouthpiece 309.
  • the mouthpiece 309 and liquid transfer element 315 are moved relative to the tank 316.
  • activation/piercing member 330 contacts and pierces a sealing element in the form of a pierceable membrane extending across the air bleed channel 332 thereby fluidly connecting the vapour flow passage 321 the storage chamber 316. This allows air from the vapour flow passage 321 to enter the storage chamber 316 as aerosol precursor is removed from the storage chamber 316 by the liquid transfer element 315.
  • liquid transfer element 315 pushes on, and moves, plug 320 out of the conduit 324 which then allows liquid transfer element 315 to come into contact with the flavoured aerosol precursor stored in the storage chamber 316.
  • the plug 320 may then be unconstrained within the storage chamber, or may be pushed by liquid transfer element 315 into a holding location.
  • a user draws (or “sucks”, “pulls”, or “puffs") on the mouthpiece 309 of the consumable 303, which causes a drop in air pressure at the mouthpiece aperture 307, thereby generating air flow through the inlet opening 306, along the airflow passage, out of the mouthpiece aperture 307 and into the user's mouth.
  • the heater 314 When the heater 314 is activated by passing an electric current through the heating filament in response to the user drawing on the mouthpiece 309 (the drawing of air may be detected by a pressure transducer), the e-liquid located in the wick 311 adjacent to the heating filament is heated and vaporised to form a vapour in the vaporising chamber 325.
  • the vapour condenses to form the e-liquid aerosol within the vapour outlet 323.
  • the e-liquid aerosol is entrained in an airflow along the vapour flow passage 321, through the aerosolisation chamber 319, to the mouthpiece aperture 307 for inhalation by the user when the user draws on the mouthpiece 309.
  • the base unit supplies electrical current to the consumable electrical contacts 113. This causes an electric current flow through the heating filament of the heater 314 and the heating filament heats up. As described, the heating of the heating filament causes vaporisation of the e-liquid in the wick 311 to form the e-liquid aerosol.
  • the constricted region of the air path results in an increase in air velocity and corresponding decrease in air pressure in the airflow in the vicinity of the porous aerosol generating portion 322.
  • the corresponding low pressure and high air velocity region causes the generation of the flavoured aerosol from the porous surface of the aerosol generating portion 322 of the liquid transfer element 315.
  • the flavoured aerosol becomes entrained in the airflow and ultimately is output from the mouthpiece aperture 307 of the consumable 303 and into the user's mouth.
  • the flavoured aerosol is sized to inhibit pulmonary penetration.
  • the flavoured aerosol is formed of particles with a mass median aerodynamic diameter that is greater than 70 microns.
  • the flavoured aerosol is sized for transmission within at least one of a mammalian oral cavity and a mammalian nasal cavity.
  • the flavoured aerosol is formed by particles having a maximum mass median aerodynamic diameter that is less than 100 microns. Such a range of mass median aerodynamic diameter will produce aerosols which are sufficiently small to be entrained in an airflow caused by a user drawing air through the device and to enter and extend through the oral and or nasal cavity to activate the taste and/or olfactory receptors.
  • the e-liquid aerosol generated is sized for pulmonary penetration (i.e. to deliver an active ingredient such as nicotine to the user's lungs).
  • the e-liquid aerosol is formed of particles having a mass median aerodynamic diameter of less than 1 micron. Such sized aerosols tend to penetrate into a human user's pulmonary system, with smaller aerosols generally penetrating the lungs more easily.
  • the e-liquid aerosol may also be referred to as a vapour.
  • the size of aerosol formed without heating is typically smaller than that formed by condensation of a vapour.
  • FIG 3C illustrates the flow of vapour through the flavour pod portion 302 of figures 3A and 3B .

  • the airflow path through the device deflects at the vapour passage inlet 304 i.e. there is a deflection between the vapour outlet 323 and the transverse portion 321a of the vapour flow passage 321.
  • the vapour flow passage 321 then deflects again from the transverse portion 321a to a longitudinal portion 321b which extends generally longitudinally between a device housing 310 (which is integral with the mouthpiece 309) and the tank 318.
  • the vapour flow passage 321 deflects again at the upper surface of the tank 318 within the mouthpiece 309 such that airflow/vapour is directed through the aerosolisation chamber 319, towards the mouthpiece aperture 307.
  • the vapour flow passage 321 may be a single (annular) flow passage around the tank 318 or it may comprises two braches which split around the tank 318 and re-join within the mouthpiece 309 proximal the liquid transfer element 315.
  • Air (comprising the e-liquid aerosol from the cartomizer portion 301 as explained above with respect to Figure 3A ) flows through the vapour outlet 323 and into the vapour passage 321. Further downstream, as air flows past the aerosol generating portion 322 in the aerosolisation chamber 319, the velocity of the air increases, resulting in a drop in air pressure. As a result, the flavoured aerosol precursor held in the aerosol generating portion 322 becomes entrained in the air so as to form the flavoured aerosol.
  • the flavoured aerosol has the particle size and other properties described above with respect to Figure 3A .
  • the liquid transfer element 315 transfers further flavoured aerosol precursor from the storage chamber 316 to the aerosol generating portion 322.

  • a body 434 of the bung 433 is received in the air bleed channel 432, but does not fully obstruct the air bleed channel 432. That is, a portion of the air bleed channel 432 remains unobstructed by the body 434 of the bung 433.
  • an enlarged head 435 of the bung 433, which is located in the storage chamber 416 extends fully across the entrance to the air bleed channel 432 so as to obstruct the channel 432.
  • an elongate activation member (extending inwardly from the mouthpiece 409) engages the body 434 of the bung 433 and pushes the bung 433 in the upstream direction (see Figure 4B ).
  • the aerosol generating portion 422 of the liquid transfer element shown in the Figures 4A and 4B has a flattened/planar upper (downstream) end surface, which is similar to that shown in Figure 3A to 3C . This is better seen in Figure 4C , which shows the mouthpiece 409 of the embodiment of Figures 4A and 4B in more detail.
  • the conveying portion 417 has a smaller cross-sectional area than the aerosol generating portion 422 of the liquid transfer element 415.
  • a step (from the conveying portion 317 to the aerosol generating portion 422) is defined by a radial transition surface 436.
  • the transition surface 436 has a concave profile such that there is a smooth transition between the conveying portion 317 and the transition surface 436 and a sharp/hard edge between the transition surface 436 and the aerosol generating portion 422.
  • This edge is an upstream leading edge of the aerosol generating portion 422 and defines an upstream end of a constricted region 438 of an airflow path between the aerosol generating portion 422 and the tube 437 defining the aerosolisation chamber 419. Downstream of this constricted region 438 is an expansion region 439. In this expansion region 329 the airflow path gradually increases in cross-sectional area in the downstream direction. This a result of the aerosol generating portion 422 having a slight inward taper towards the planar distal end surface 429 and the cylindrical shape of the aerosolisation chamber 419.
  • the collar 408 which partially circumscribes the liquid transfer element 415.
  • the collar 408 is connected to a mounting portion 440, which surrounds the tube 437 so as to mount the collar 408 to the tube 437.
