Definitions

  • the present invention relates to a filter segment and a tobacco product.

Therefore, in recent years, the filter segments of cigarettes and non-combustion heated tobacco products are required to include a plurality of filter segments having their respective functions and to shorten the axial length of each filter segment to about 5 to 15 mm. ..
  • the filter segment is manufactured by cutting a continuous rod-shaped body obtained by bundling a large number of long fibers such as cellulose acetate fibers and continuously winding them on a plane perpendicular to the longitudinal direction. Since the fibers constituting the filter segment extend substantially parallel to the axial direction of the filter segment, the destructive capsule may be displaced when an external force is applied to the filter segment containing the destructive capsule. If the destructive capsule is misaligned, the destructive capsule may not be easily crushed. In particular, when the length of the filter segment in the axial direction is short, the holding capacity of the destructive capsule is low because there are few places where the fibers are entangled with each other, and the position of the destructive capsule is likely to shift when an external force is applied. Also, significant misalignment can cause the destructive capsule to deviate out of the filter segment.
  • An object of the present invention is to provide a filter segment in which the misalignment of the destructive capsule is suppressed even when an external force is applied, and a tobacco product containing the filter segment.
