Definitions

  • the present invention relates to a flavor inhaler including a carbon heat source and a tubular member.
  • a flavor inhaler that includes a heat source having a columnar shape and a tubular member having a tubular shape is known.
  • one end portion of the tubular member configures a mouthpiece, and the other end portion of the tubular member configures a supporting portion that supports the heat source.
  • a technology is proposed in which a carbon heat source comprising 10 to 60 wt% of carbon is used as the heat source.
  • the carbon heat source is arranged to be exposed from the tubular member (for example, Patent Literature 1).
  • the heat source is previously attached to the tubular member, and thus, a flavor ingredient moves between the heat source and an internal member of the tubular member (in this case, an ingredient comprised in the flavor source moves to the heat source), and this result is a concern over deteriorating of a flavor inhaling taste.
  • the holder is repeatedly used, and thus, a structure of the holder is highly complicated, and a manufacture cost of the holder is high. Therefore, the holder described in the Patent Literature 2 is not suitable for being disposable. Further, the heat source and the flavor source are kept separated of the holder, and thus, it is necessary that the heat source is mounted to the holder that houses therein the flavor source after the flavor source is mounted to the holder, and such a task is a cumbersome task for user.
  • a flavor inhaler comprises: a heat source having a columnar shape extending along a predetermined direction; and a tubular member previously housing a flavor source and having a tubular shape.
  • the heat source and the tubular member are a disposable member.
  • the heat source is provided separately of the tubular member that previously houses the flavor source.
  • the tubular member is configured by a member having more flexibility than the heat source.
  • the tubular member is a paper tube configured by at least one of a laminated paper and a thick paper of a heat conduction member.
  • the tubular member is a simple tube paper formed by winding a sheet-like member into a tubular shape, the sheet-like member configured by at least one of a laminated paper and a thick paper of a heat conduction member.
  • an external dimension of the heat source is approximately equal to an internal dimension of the tubular member.
  • one end portion of the heat source is an ignition end portion and the other end portion of the heat source is an insertion end portion inserted into the tubular member along the predetermined direction, and the insertion end portion has an inclination surface having an inclination relative to the predetermined direction.
  • one end portion of the tubular member is a mouthpiece and the other end portion of the tubular member is a supporting portion that supports the heat source.
  • the supporting portion has such a shape that an internal dimension of the supporting portion is smaller as it is closer to the mouthpiece.
  • a flavor inhaler comprises: a heat source having a columnar shape extending along a predetermined direction; and a tubular member previously housing a flavor source and having a tubular shape.
  • the heat source and the tubular member are a disposable member.
  • the heat source is provided separately of the tubular member that previously houses the flavor source.
  • the tubular member is configured by a member having more flexibility than the heat source.
  • a tubular member is a disposable member that previously houses a flavor source. Therefore, it is not necessary for a user to mount a flavor source to the tubular member, and thus, it is possible to alleviate a user's task.
  • a carbon heat source is provided separately of the tubular member that previously houses the flavor source. Therefore, an ingredient comprised in the flavor source does not move to the carbon heat source before the flavor inhaler is used. Thus, it is possible to restrain a flavor inhaling taste from deteriorating.
