Description

The present invention relates to an electronic cigarette cartridge using a tobacco plant or a non-tobacco plant and a supporting member thereof.

In recent years, in order to match the tendency of smoking cessation of cigarettes, electronic cigarette products for enjoying cigarettes have become widespread by heating cartridges containing tobacco components and sucking vaporized tobacco components without using flames. It has begun (see, for example, Patent Document 1 below).

In the electronic cigarette of Patent Document 1, a heating element is inserted into the aerosol-forming base material of the cartridge to heat the aerosol-forming base material to generate an aerosol containing a tobacco component. The cartridge has a hollow tubular support element that supports the aerosol-forming substrate, which resists the forces that the cartridge receives as the heating element is inserted into the aerosol-forming substrate. The tobacco component released from the aerosol-forming substrate by heating is transferred to the mouthpiece located downstream through the hollow portion of the support element and sucked by the user.

The aerosol-forming base material 110 is produced, for example, by powdering the above-mentioned material, mixing it with glycerin or oil, kneading it, and then making it into a rod shape and drying it. Alternatively, it is produced by making a paste containing water without drying.

As shown in FIG. 3, when the shape of the filler 111 manufactured as the aerosol-forming base material 110 is, for example, a rod shape or a strip shape, the longitudinal direction of the shape of the filler 111 is set to the X direction at the time of filling. It is packed so that it follows. This stabilizes the airflow and makes it easier for the user to inhale the aromatic components from the aerosol-forming substrate 110.

Note that FIG. 3 is a view seen from the end of the electronic cigarette cartridge 100 on the side where the aerosol-forming base material 110 is located, and is partially viewed from the perspective so that the filler 111 inside the electronic cigarette cartridge 100 can be seen. Of course, in addition to this, if it is a flat plate-shaped filling, it may be rolled and packed, or if it is a small piece-shaped filling, it may be packed randomly.

As shown in FIG. 4, the electronic cigarette cartridge 100 is attached to the electronic cigarette body 200 at the time of use by the user. The electronic cigarette body 200 is provided with an insertion portion 210 for inserting the electronic cigarette cartridge 100.

Further, a heating element 211 is provided in the central portion of the bottom of the insertion portion 210, and the heating element 211 has a pin-shaped or blade-shaped member having a sharp tip, and is inside the aerosol-forming base material 110. And heats the aerosol-forming substrate 110. More specifically, the heating element 211 is inserted into the central portion of the aerosol-forming base material 110 when the electronic cigarette cartridge 100 is inserted into the insertion portion 210 of the electronic cigarette body 200.

The heating element 211 directly or indirectly generates heat by the electric power supplied from a battery (not shown) provided in the electronic cigarette body 200. The heat of the heating element 211 heats the aerosol-forming base material 110 to generate an aerosol containing an aromatic component. Then, the generated aerosol is transferred to the mouthpiece 140 via the support member 120 and the cooling member 130 (in the case of being illustrated in FIG. 2B) described below, and the user sucks the aerosol from the mouthpiece 140 side to obtain a fragrance. The ingredients will reach the user's mouth.

Although FIG. 4 shows a case where the heating element 211 has one pin-shaped member, the heating element 211 may have a plurality of pin-shaped members.

<Support member 120> The support member 120 supports the aerosol-forming base material 110. The support member 120 is arranged adjacent to the aerosol-forming substrate 110 and has a central portion 121 and a plurality of side portions 122. The central portion 121 is located along the central axis in the longitudinal direction (X direction) of the electronic cigarette cartridge 100. The plurality of side portions 122 extend outward from the central portion 121 and come into contact with the packaging member 150 located on the peripheral edge of the electronic cigarette cartridge 100. The side portion 122 is fixed to the inner surface of the packaging member 150 by, for example, an adhesive.

Further, another member may be arranged between the aerosol-forming base material 110 and the support member 120. That is, the support member 120 may be arranged with another member sandwiched between the aerosol-forming base material and the support member 120. Other members may include, for example, a thin filter that removes fine particles from the filler 111, another support member that supports the aerosol-forming substrate 110, and the like.

As shown in FIG. 4, the support member 120 resists the force received by the electronic cigarette cartridge 100 when the heating element 211 of the electronic cigarette body 200 is inserted into the aerosol-forming base material 110, and the aerosol-forming base material 110 is used. Prevents or suppresses movement in the X direction.

More specifically, since the side portion 122 of the support member 120 is fixed to the inner surface of the packaging member 150, the peripheral portion of the aerosol-forming base material 110 can be reliably supported. Further, since the support member 120 has the central portion 121, it is possible to prevent the filler 111 at the central portion of the aerosol-forming base material 110 from being pushed out in the X direction by the heating element 211 inserted into the aerosol-forming base material 110. As described above, in the support member 120 of the present embodiment, the aerosol flow path is provided not in the central portion where the force exerted by the heating element 211 acts, but in the peripheral portion.

The aerosol generated by heating the aerosol-forming base material 110 is generated from the one end portion of the electronic cigarette cartridge 100 by using the space formed between the central portion 121 and the inner surface of the packaging member 150 covering the support member 120 as a flow path. Transferred towards the other end (see arrow in the figure).

As described above, in the present embodiment, the support member 120 has a central portion 121 and a plurality of side portions 122. The central portion 121 and the plurality of side portions 122 can be integrally formed by using, for example, a mold. By forming the shape as in Examples 1 to 4 described above, the support member 120 can be easily pulled out from the mold when molding, so that the support member 120 can be manufactured more easily than the hollow tubular support member.

Further, the support member 120 can be preferably formed by using, for example, silicone, but the support member 120 is not limited to silicone, and other materials having excellent heat resistance may be used.

<Cooling member 130> As shown in FIG. 2B, the cooling member 130 cools the aerosol that has passed through the support member 120. The cooling member 130 is arranged on the side opposite to the aerosol-forming base material 110 with the support member 120 interposed therebetween, and is adjacent to the support member 120. The aromatic component contained in the aerosol produced by the aerosol-forming substrate 110 is transferred along the cooling member 130, cooled to a temperature that can be sucked by a person, and transferred to the mouthpiece 140. The cooling member 130 has, for example, a sheet containing polylactic acid, and the sheet includes a plurality of folds. Alternatively, the sheet is rolled up or folded and contracted in a direction orthogonal to the X direction.

The length of the cooling member 130 in the X direction can be adjusted according to the length of the support member 120 in the X direction. As shown in FIG. 2 (A), when the length of the support member 120 in the X direction is long (for example, 26.5 mm), the support member 120 has a function of supporting the aerosol-forming base material 110 and the aerosol. It also has the function of cooling the contained aromatic components to a temperature that can be inhaled by humans. Therefore, the cooling member 130 can be omitted. As a result, the production cost of the electronic cigarette cartridge 100 can be reduced.

<Mouthpiece 140> The mouthpiece 140 is adjacent to the cooling member 130 or the support member 120, and is arranged at the other end of the electronic cigarette cartridge 100. The mouthpiece 140 includes, for example, a cellulose acetate filter as a filter for removing fine particles. The aromatic component that has passed through the filter of the mouthpiece 140 is sucked by the user. The mouthpiece 140 is fixed to the inner surface of the packaging member 150 by, for example, an adhesive.

The electronic cigarette cartridge 100 having the support member 120 and the support member 120 of the present embodiment described above has the following effects.

A space is formed between the central portion 121 of the support member 120 and the inner surface of the packaging member 150 that covers the support member 120. Therefore, the aerosol-forming base material 110 can be stably supported by the central portion 121 when the heating element 211 is inserted into the aerosol-forming base material 110 while securing the flow path through which the aerosol is transferred.

Further, since the aerosol-forming base material 110 produces an aerosol containing an aromatic component of a non-tobacco plant, the user can enjoy the scent of the plant. It can also be used as a tobacco substitute by users with smoking habits. Furthermore, it can be expected to improve the health of the user by producing aroma components of plants that are beneficial to the health of the user.

The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the claims.

For example, in the above-described embodiment, the case where the central portion and the plurality of side portions of the support member are integrally formed has been described. However, the present invention is not limited to the case where the central portion and the plurality of side portions are integrally formed, and the central portion and the plurality of side portions are configured to be combined after being formed separately. May be good.

Further, in Examples 1 to 4 described above, the case where the cross section of the support member has a shape in which the peripheral edge portion of the disk is cut out at two or four places in a rectangular shape has been described. However, the cross section of the support member is not limited to such a shape, and may be a shape in which the peripheral edge portion of the disk is cut out at three or five or more places in a rectangular shape, or a triangular shape or a polygonal shape instead of a rectangular shape. It may be a shape, a semicircular shape, a semi-elliptical shape, or any other shape cut out in any form composed of a curved line, a straight line, or a combination thereof.
