Definitions

  • Aerosol generating articles for example heated smoking articles, may be configured so that the combustible heat source is blind, which may limit the amount or number volatile compounds released from combustion of the heat source that enter air drawn through the smoking article.
  • Heated smoking articles having blind combustible heat sources may transfer heat to the aerosol-generating substrate primarily via conduction.
  • Heated smoking articles may also be configured so that the heat source is non-blind.
  • Heated smoking articles having non-blind combustible heat sources transfer heat to the aerosol-generating substrate primarily via convection through one or more air flow channels through the heat source, which allow volatile compounds from the heat source to enter air drawn through the smoking article. Because one aim of heated smoking articles is to reduce certain smoke constituents produced via combustion, heated smoking articles employing blind heat sources may be preferred.
  • heated smoking articles may require direct contact with air to burn properly.
  • heated smoking articles may be manufactured such that the heat source is exposed to a smoker and their surroundings during smoking.
  • temperatures of the combustible heat sources may be quite high when burning.
  • temperatures of the heat sources during combustion may be more than 600° C.
  • the invention provides an assembly comprising a holder and an aerosol generating article.
  • the aerosol generating article comprises a heat source and aerosol generating substrate downstream of the heat source and conductively coupled to the heat source such that heat from the heat source is transferred to the aerosol generating substrate without combusting the aerosol generating substrate.
  • the aerosol generating article further comprises a wrapper circumscribing the aerosol generating substrate.
  • the wrapper defines one or more ventilation through holes
  • the holder comprises a mouthpiece having a mouth end and a distal end and defines a passage extending from the mouth end to the distal end. The passage is configured to receive, for example slidably receive, the aerosol generating article inserted in a direction from the distal end towards the mouth end.
  • Aerosol generating articles according to the invention have a proximal end through which, in use, an aerosol exits the article for delivery to a user, and have an opposing distal end.
  • the proximal end of the aerosol generating article may also be referred to as the mouth end.
  • a user draws on the proximal end of the aerosol generating article in order to inhale an aerosol generated by the aerosol generating article.
  • upstream and downstream are relative to the direction of aerosol movement through the aerosol generating article when a user draws on the proximal end.
  • holders according to the present invention may have one or more advantages relative to currently available aerosol generating articles that include a combustible heat source.
  • holders according to the invention provide a simple to use barrier to protect a smoker or their surrounding environment from contact with a combusted heat source having a high temperature.
  • the cage of the end piece that surrounds the heat source may be separated from the heat source so that the temperature of the cage is lower than the temperature of the combusted heat source.
  • the cage may also be configured to efficiently dissipate heat to reduce temperature of the cage relative to the combusted heat source.
  • one or more additional elements disposed in the passage may engage the aerosol generating article.
  • the aerosol generating article is preferably retained in a longitudinal position relative to the mouthpiece in use.
  • the aerosol generating article is preferably insertable or removable from the passage with minimal force.
  • the aerosol generating article may be readily inserted or withdrawn from the passage by a user.
  • the cage preferably has sufficient permeability to allow air to access the heat source through the cage to maintain combustion of the heat source.
  • permeability refers to a percent of total area of a surface or a portion of a surface that is void space area.
  • at least a portion of the cage that surrounds the heat source has sufficient permeability to allow a lighting of the heat source by a flame.
  • the heat source can be lit through the cage.
  • the cage comprises a distal face defining an opening that has a cross sectional area that is the same as the bore of the cage.
  • the cage comprises openings, such as through-holes, disposed radially about the heat source.
  • the cage comprises ventilation through-holes downstream of the portion surrounding the heat source.
  • such holes allow cool air to be drawn through the aerosol generating article.
  • the cage comprises a non-permeable wall between the distal end of the cage and the downstream ventilation openings. Such a wall may reduce the amount or number of combustion products from the heat source from entering the air drawn into the aerosol generating article.
  • a holder according to the present invention is configured to allow an aerosol generating article to be inserted, mouth end first, into a passage defined by the mouthpiece until the mouth end engages a shoulder or tapered portion in proximity to the mouth end. If the cage is slidable over the mouthpiece, the cage may be distally advanced over the mouthpiece until the cage engages the mouthpiece and further advancement is prevented. Distal movement of the cage may occur until, for example, a proximal stop of the cage engages a distal flange of the mouthpiece. Openings at the distal portion of the cage allow for lighting of the heat source, continued combustion of the heat source, and evacuation of combustion gasses when the aerosol generating article is fully inserted into the holder.
  • Openings in the cage permit outside air to be drawn into the aerosol generating article, through or around a heated aerosol generating substrate and into a user's mouth.
  • the openings that permit outside air to be drawn through the aerosol generating article are separated from more distal cage openings by a seal.
  • the cover may be moved to cover distal openings in the cage to aid in extinguishing the heat source. If the mouthpiece is telescoping, the mouth end can be pressed and moved distally relative to the distal end of the mouthpiece to eject the extinguished smoking article.

  • the combustible heat source has a mass of between about 300 mg and about 500 mg, more preferably of between about 400 mg and about 450 mg.
