Definitions

  • the present invention relates to an aerosol generation device, and more precisely to a cartomizer intended for equipping an aerosol generation device.
  • the aerosol-forming liquid needs to be preserved by protection means with barrier properties.
  • protection means is intended for protecting against the permeability of gases and vapor.
  • oxygen has a tendency to oxidize nicotine, which reduces the nicotine concentration in the aerosol-forming liquid and changes the colour of the liquid, that consequently has an impact on the user’s product satisfaction and deviation from the labelled value beyond what is acceptable from a quality and/or legal standpoint.
  • a lot of aerosol-forming liquid comprise hygroscopic components, such as propylene glycol and vegetable glycerin, and nicotine, which all have a tendency to absorb water which negatively influences the user’s sensory experience.
  • the overall protection means of the cartomizer which dictates shelf-life, comprises a structural or secondary packaging, a primary packaging and the cartomizer.
  • the primary packaging usually provides the main barrier properties. It is typically manufactured from materials with very high gas and vapor barrier properties, such as aluminum and/or Polyethylene terephthalate (PET) coated with Polyvinylidene chloride (PVDC) in a blister pack format.
  • PET Polyethylene terephthalate
  • PVDC Polyvinylidene chloride
  • the secondary packaging may also comprise an external film that reduces ingress of vapor and/or gas.
  • the cartomizer and in particular its body or outer casing, provides actually very low barrier properties due to two main reasons: i) many current cartomizers have an open design (for instance due to air inlet(s)) that allows an air flow to go through the body and mix with the generated vapor to form the aerosol, which exposes the aerosol-forming liquid to the environment, and ii) the body materials used to define the reservoir that houses the aerosol-forming liquid have challenging requirements, such as a high chemical resistance to prevent migration of harmful chemical components or substances to the content of aerosol-forming liquid in quantities which could change its composition or the generated aerosol and thereby could increase the user’s risk.
  • the cartomizer is a consumable and therefore it is desirable to manufacture its body with high-volume and cost- effective techniques, such as injection molding of thermoplastics.
  • an object of this invention is to improve the situation, and notably to allow decreasing the barrier properties requirements of the primary or secondary packaging of the cartomizers.
  • the entire body may be formed of the polymer multilayer structure.
  • the high or very high protection is (are) now achieved at least partially by the cartomizer body, which allows a possible use of simpler, lower-cost, and more environmentally friendly (or sustainable) materials for the packaging of the cartomizer.
  • a user interface 28 may be coupled to the controller 27 and the power source 23 to allow the user to control at least partly the controller 27.
  • the user interface 28 may comprise a display (such as a screen or light emitting diode (or LED)-type interface) arranged for displaying information relative to a current vaping session or a possible current charging session and for allowing the user to control the controller 27.
  • the user interface 28 may be fixed partly to the printed circuit board 29 to ease and simplify its connections with the controller 27.
  • the aerosol chamber 7 may comprise an aerosol-forming liquid transport element 33 to transport aerosol-forming liquid from the openings 15 of the internal wall 6 to the heater 18.
  • this aerosol-forming liquid transport element 33 may be a capillary element (possibly a capillary wick) having two opposite ends set in front of the openings 15, and possibly against the latter (and therefore against the internal surface of the internal wall 6).
  • the aerosol forming liquid transport element 33 may traverse two large openings (larger than those referenced 15) and defined in the internal wall 6 to finish in the reservoir 5.
  • each protection layer 20 provides the high/very high gas and/or moisture barrier properties or absorption.
  • the protection layer 20 may have a water vapor transmission rate (WVTR) that is less than 10 g/m 2 /24 hours.
  • WVTR water vapor transmission rate
  • its WVTR may be less than 6 g/m 2 /24 hours, and more preferably less than 1 g/m 2 /24 hours.
  • the polymer multilayer structure 19 may comprise an outer layer 21 made of thermoplastic co-polyester, a protection layer 20 made of EVOH or COC, and an inner layer 21 made of thermoplastic co-polyester.
  • the removable protection elements 31 may have a water vapor transmission rate (WVTR) that is less than 10 g/m 2 /24 hours, preferably than 6 g/m 2 /24 hours, and more preferably less than 1 g/m 2 /24 hours.
  • WVTR water vapor transmission rate
  • the removable protection elements 31 may have an oxygen transmission rate (OTR) that is less than 10 cm 3 /m 2 /24 hours, preferably less than 6 cm 3 /m 2 /24 hours, and more preferably less than 3 cm 3 /m 2 /24 hours.
  • OTR oxygen transmission rate
  • the removable protection elements 31 may be formed of a polymer material having a water vapor transmission rate (WVTR) that is less than 40 g.pm/m 2 /24 hours, and preferably less than 4 g.pm/m 2 /24 hours.
  • WVTR water vapor transmission rate
  • this polymer material to form the at least one layer of the removable protection elements 31 may have an oxygen transmission rate less (OTR) that is less than 40 cm 3 .pm/m 2 /24 hours, and preferably less than 4 cm 3 .pm/m 2 /24 hours.
  • OTR oxygen transmission rate less
  • the cartomizer body 4 may be formed of a single piece.
  • the whole reservoir 5 may be defined by compartmenting walls (and notably the outer one 17) that all have the polymer multilayer structure 19.
  • the cartomizer body 4 could be formed of two pieces welded together.
  • the mouthpiece 8 may form a part of the containment walls 30. But in a variant of embodiment, the mouthpiece 8 could overlay a containment wall 30 of the reservoir 5.
  • the containment walls 31 include the outer wall 17 (notably the part defining partly the reservoir 5) and the aerosol chamber 7 (with the heater 18).
  • the mouthpiece 8 can be removable to allow access to one of the protection elements 31 .
  • a first removable protection element 31 is stuck to the end of the internal wall 6 that is intended for being oriented towards the electrical and control device 3 in order to close the first inlet 11, and a second removable protection element 31 is stuck to the outer face of the internal wall defining partly the reservoir 5 in order to close the end of the central conduit 9 at the level of the aerosol outlet 16.
  • a first removable protection element 31 is stuck to the end of the internal wall 6 that is intended for being oriented towards the electrical and control device 3 in order to close the first inlet 11, and a second removable protection element 31 is stuck to the outer face of the mouthpiece 8 to close the aerosol outlet.
