Definitions

  • the invention relates to flavor inhalers and insertion guide members.
  • flavor inhalers used to inhale flavors without burning base material containing a flavor source.
  • These well-known flavor inhalers include an electrical smoking system with a heating element that slidingly receives a cigarette inserted into a cigarette receiver (see Patent Literature 1, for example).
  • An object of the invention is to provide a flavor inhaler and an insertion guide member which have novel structures.
  • the flavor inhaler is used with a rod-like flavor generating article.
  • the flavor inhaler comprises an insertion guide member including an opening in which the flavor generating article can be inserted, an inner peripheral surface enclosing an outer periphery of the flavor generating article inserted from the opening, and a ring-like protruding portion that protrudes from the inner peripheral surface to extend over an entire circumference of the inner peripheral surface and abuts on the flavor generating article over the entire circumference of an outer peripheral surface of the inserted flavor generating article.
  • the protruding portion includes, in a circumferential direction of the inner peripheral surface, a portion that changes in a position in the longitudinal direction of the flavor generating article that abuts on the outer peripheral surface of the inserted flavor generating article.
  • Another embodiment of the invention provides the above-mentioned flavor inhaler and an insertion guide member.
  • a flavor inhaler according to the present embodiment is used with a rod-like flavor generating article.
  • Fig. 1A is a perspective overall view of the flavor inhaler according to the present embodiment.
  • Fig. 1B is a perspective overall view of the flavor inhaler according to the embodiment which holds a flavor generating article.
  • a flavor inhaler 10 according to the present embodiment is configured to generate aerosol containing a flavor, for example, by heating a flavor generating article 110 that includes a flavor source containing an aerosol source.
  • the flavor inhaler 10 includes a top housing 11A, a bottom housing 11B, a cover 12, a switch 13, a lid portion 14, a first vent hole 15, and a cap 16.
  • the top housing 11A and the bottom housing 11B are connected together to form an outer housing 11 located at an outermost side of the flavor inhaler 10.
  • the outer housing 11 is of a size that fits in a user's hand. When using the flavor inhaler 10, the user can inhale a flavor while holding the flavor inhaler 10 in his or her hand.
  • the top housing 11A includes an opening, not shown.
  • the cover 12 is connected to the top housing 11A so as to close the opening.
  • the cover 12 includes an opening 12a in which the flavor generating article 110 can be inserted.
  • the lid portion 14 is configured to open/close the opening 12a of the cover 12.
  • the lid portion 14 is mounted on the cover 12 and configured to be movable between a first position for closing the opening 12a and a second position for opening the opening 12a along a surface of the cover 12.
  • the lid portion 14 thus allows or restricts access of the flavor generating article 110 to the inside of the flavor inhaler 10 (opening 61 of an insertion guide member 17 illustrated in Fig. 4 ).
  • the switch 13 is used to switch between ON and OFF of actuation of the flavor inhaler 10. For example, if the user operates the switch 13 with the flavor generating article 110 inserted in the opening 12a as illustrated in Fig. 1B , electric power is supplied from a power source, not shown, to a heating member, not shown. The user thus can heat, instead of burning, the flavor generating article 110. When the flavor generating article 110 is heated, aerosol is vaporized from an aerosol source contained in the flavor generating article 110, and the flavor of the flavor source is captured in the aerosol. The user can inhale the aerosol containing the flavor by sucking a portion of the flavor generating article 110 which is protruding from the flavor inhaler 10 (portion illustrated in Fig. 1B ).
  • the first vent hole 15 is a vent hole for introducing air into the inside of a heating assembly 41 (see Fig. 3 ) that is housed in an interior space of the outer housing 11.
  • the cap 16 is attachable to and detachable from the bottom housing 11B.
  • the cap 16 is mounted on the bottom housing 11B, to thereby form the first vent hole 15 between the bottom housing 11B and the cap 16.
  • the cap 16 may include, for example, a through-hole, a notch or the like, not shown.
  • a longitudinal direction of the flavor inhaler 10 refers to a direction the flavor generating article 110 is inserted into the opening 12a.
  • a side into which air enters is an upstream side
  • a side from which air exits is a downstream side.
  • Fig. 2 is a cross-section of the flavor generating article 110.
  • the flavor generating article 110 comprises a base material portion 110A that includes a filler 111 and a first paper wrapper 112 for wrapping the filler 111, and a mouthpiece portion 110B that forms an end portion on an opposite side to the base material portion 110A.
  • the base material portion 110A and the mouthpiece portion 110B are connected together by a second paper wrapper 113 that is another paper wrapper than the first paper wrapper 112.
  • the second paper wrapper 113 may be omitted, and the first paper wrapper 112 may be used to connect the base material portion 110A and the mouthpiece portion 110B.
  • the mouthpiece portion 110B illustrated in Fig. 2 includes a paper tube portion 114, a filter portion 115, and a hollow segment portion 116 disposed between the paper tube portion 114 and the filter portion 115.
  • the hollow segment portion 116 comprises, for example, a filling layer including one or more hollow channels, and a plug wrapper that covers the filling layer.
  • the filling layer has a high fiber packing density. During inhalation, therefore, air and aerosol flow only through the hollow channel or hollow channels and hardly flow through the filling layer.
  • the mouthpiece portion 110B illustrated in Fig. 2 comprises three segments. According to the present embodiment, however, the mouthpiece portion 110B may comprise one or two segments or may comprise four or more segments. It is also possible, for example, to omit the hollow segment portion 116 and arrange the paper tube portion 114 and the filter portion 115 adjacent to each other to form the mouthpiece portion 110B.
  • the flavor generating article 110 has a longitudinal length ranging preferably from 40 mm to 90 mm, more preferably from 50 mm to 75 mm, and still more preferably from 50 mm to 60 mm.
  • the flavor generating article 110 has a circumference ranging preferably from 15 mm to 25 mm, more preferably from 17 mm to 24 mm, and still more preferably from 20 mm to 23 mm.
  • the base material portion 110A of the flavor generating article 110 may have a length of 20 mm.
  • the first paper wrapper 112 may have a length of 20 mm.
  • the hollow segment portion 116 may have a length of 8 mm.
  • the filter portion 115 may have a length of 7 mm. The length of each of the foregoing segments may be changed as necessary according to manufacturability, required quality, and the like.
  • the filler 111 of the flavor generating article 110 may contain the aerosol source that is heated at predetermined temperature and generates aerosol.
  • the aerosol source may be of any kind. Materials extracted from various natural products and/or components thereof may be selected according to the intended use.
  • the aerosol source may be, for example, glycerin, propylene glycol, triacetin, 1, 3-butanediol or a mixture of these substances.
  • An amount of the aerosol source contained in the filler 111 is not particularly limited.

  • the filler 111 of the flavor generating article 110 may contain shred tobacco as a flavor source.
  • the shred tobacco may be made of any material including publicly-known materials, such as laminae and stems. If the flavor generating article 110 has a circumference of 22 mm and a length of 20 mm, the amount of the filler 111 contained in the flavor generating article 110 ranges, for example, from 200 mg to 400 mg and preferably from 250 mg to 320 mg.
  • a moisture content of the filler 111 ranges, for example, from 8% by weight to 18% by weight and preferably from 10% by weight to 16% by weight.
  • the moisture content in the above ranges suppresses the adhesion of a stain on the paper wrappers and improves a winding efficiency during manufacture of the base material portion 110A.
  • size or preparation method for the shred tobacco used as the filler 111 may be prepared using dried tobacco leaves that are cut into pieces each having a width ranging from 0.8 mm to 1.2 mm.
  • the dried tobacco leaves also may be pulverized into particles with an average particle diameter ranging from about 20 ⁇ m to about 200 ⁇ m to be equalized in size, processed into a sheet, and then shredded into pieces each having a width ranging from 0.8 mm to 1.2 mm.
  • the dried tobacco leaves subjected to the above-described sheet processing may be gathered together, instead of being shredded, and used as the filler 111.
  • the filler 111 may include one or more kinds of aroma chemicals.
  • the aroma chemical may be of any kind but is preferably menthol from a perspective of addition of a favorable smoking flavor.
  • the first and second paper wrappers 112 and 113 of the flavor generating article 110 may be made of base paper having a basis weight ranging, for example, from 20 gsm to 65 gsm, and preferably from 25 gsm to 45 gsm.
  • the first paper wrapper 112 and the second paper wrapper 113 are not particularly limited in thickness.

  • the loading material preferably ranges from 15% by weight to 45% by weight relative to the preferable range of basis weight (from 25 gsm to 45 gsm).
  • the loading material may be, for example, calcium carbonate, titanium dioxide, kaolin or the like.
  • the paper containing such a loading material shows a bright white color that is preferable in view of appearance of the paper used as paper wrapper for the flavor generating article 110, and can permanently maintain whiteness.
  • the paper wrapper containing a large amount of such a loading material has, for example, an ISO brightness of 83% or more.
  • the first and second paper wrappers 112 and 113 preferably have a tensile strength of 8 N/15 mm or higher.
  • the tensile strength can be increased by reducing the contained amount of the loading material.
  • the tensile strength can be increased by reducing the contained amount of the loading material to be lower than an upper limit of the contained amount of the loading material within each of the base weight ranges as exemplified above.

  • the enclosing portion 66 encloses the outer periphery of the downstream end of the container 42.
  • a region where the outer peripheral surface of the flavor generating article 110 is away from the inner peripheral surface 62, that is, a gap is formed at each of longitudinally located positions in the flavor generating article 110 in a region where the outer peripheral surface of the inserted flavor generating article 110 abuts on the protruding portion 63. Therefore, if the outer peripheral surface of the flavor generating article 110 receives pressure from the protruding portion 63 during the insertion and/or removal of the flavor generating article 110, at least part of the pressure is used for movement and/or deformation of the flavor generating article 110 in the gaps.
  • a perpendicular reaction force that is actually applied to the outer peripheral surface of the flavor generating article 110 from the protruding portion 63 is smaller than the pressure in a case where the gaps are not formed. According to the above-described configuration, the perpendicular reaction force is small, which is applied to the outer peripheral surface of the flavor generating article 110 from the protruding portion 63. This reduces a frictional force acting on the flavor generating article 110 during the insertion and/or removal of the flavor generating article 110.
  • the protruding portion 63 abuts on the flavor generating article 110 over the entire circumference of the outer peripheral surface of the inserted flavor generating article 110, which prevents thermal vapor generated in the heating portion 40 from leaking through the opening 61.
  • the protruding portion 63 may be configured to abut on a part of each of longitudinally located portions of the inserted flavor generating article 110, which is easy to be elastically deformed by receiving a radially inward pressure.
  • the protruding portion 63 may be configured to abut on the paper tube portion 114 in the flavor generating article 110 illustrated in Fig. 2 .
  • the guide portion 64 includes the guide surface 64a disposed to face the outer peripheral surface of the inserted flavor generating article 110, the guide surface 64a prevents the inserted flavor generating article 110 from oscillating about the horizontal portion 63c serving as a fulcrum.
  • the insertion guide member 17 may be formed by combining a plurality of members. This makes it easy to form the insertion guide member 17 having a complicated shape.
  • the protruding portion 63 may be formed at a joint between the plurality of members. If the plurality of members are combined, it is necessary to eliminate a step created at the joint between the plurality of members. However, if the step is used as the protruding portion 63, the process of eliminating the step can be omitted.
  • the non-protruding portion 62a may be formed only either on the opening 61 side of the protruding portion 63 or on the opposite side from the opening 61.
  • the convex portions 63b do not necessarily have to be provided in two places and may be provided in three or more places as long as the convex portions 63b are disposed at regular intervals in the circumferential direction of the inner peripheral surface 62.
  • the inner peripheral surface 62 may be provided with only one convex portion 63b.
  • the guide portion (first guide portion) 64 may extend from the horizontal portion 63c toward the opening 61 (upper side on Fig. 5 ) along the longitudinal direction of the inserted flavor generating article 110.
  • the guide portion 64 may extend only from either one of the horizontal portions 63c.

  • Fig. 13 is a cross-section of the inner peripheral surface 62 taken along and viewed in a direction of an arrow 13-13 shown in Fig. 11 .
  • the protruding portion 63 is formed of an inclined portion 63a extending at an angle to a longitudinal direction of an inserted flavor generating article 110. According to the above-described configuration, a perpendicular reaction force that is applied to an outer peripheral surface of the flavor generating article 110 from the protruding portion 63 can be evenly dispersed in the longitudinal direction of the flavor generating article 110. There is one or two contact points between the protruding portion 63 and the flavor generating article 110 at each of longitudinally located positions in the flavor generating article 110 in a region where the outer peripheral surface of the inserted flavor generating article 110 abuts on the protruding portion 63. This enlarges a gap at each of the longitudinally located positions in the flavor generating article 110 and thus facilitates movement and/or deformation of the flavor generating article 110.

Since the guide portion 64 extends from the opening 61-side (upper side on Fig. 14 ) end portion of the of the protruding portion 63 to the opposite side from the opening 61 (lower side on Fig. 14 ), the guide portion 64 is capable of guiding movement of the flavor generating article 110 to a large extent in the longitudinal direction of the flavor generating article 110.
  • the guide portion 64 does not necessarily have to extend from the opening 61-side (upper side on Fig. 14 ) end portion of the protruding portion 63 and may extend from anywhere in the protruding portion 63.
