Definitions

  • FIG. 1 is a perspective view showing a cigarette with a filter according to the first embodiment of the present invention.
  • FIG. 2 is a side view of the cigarette with a filter shown in FIG.
  • FIG. 3 is a perspective view showing a cigarette with a filter according to the second aspect of the present invention.
  • FIG. 4 is a side view of the cigarette with a filter shown in FIG.
  • FIG. 5 is a side view partially showing a cigarette with a filter according to the third aspect of the present invention.
  • 6 is a perspective view partially showing the filter-attached cigarette shown in FIG.
  • FIG. 7 is a side view partially showing a cigarette with a filter according to the fourth aspect of the present invention.
  • FIG. 8 is a perspective view partially showing the filter-attached cigarette shown in FIG.
  • FIG. 9 is a schematic front view showing a cigarette package in which a plurality of cigarettes with filters shown in FIGS. 1 and 2 are accommodated.
  • the upper surface of the obtained oblique cutting cylinder is composed of an arc plane parallel to the lower bottom surface and an inclined elliptic arc plane having a common chord with the arc chord of the arc plane.
  • This elliptical arc is axisymmetric with respect to the major axis of the ellipse including the elliptical arc.
  • the inclined plane of the filter usually intersects the extension of the cigarette rod axis.
  • the acute angle ⁇ formed between the elliptical inclined plane 121 and the extension line of the axis AX of the cigarette rod 110 is 28 from the viewpoint of easy picking up of the cigarette (easy picking with a finger). It is preferably greater than 80 degrees and less than 72 degrees, more preferably greater than 28 degrees and 58 degrees or less.
  • a cigarette rod between two points on the outer peripheral surface of a filter 120 that defines the major axis of the ellipse of the inclined plane 121 (precisely, it is a chip paper 130 but is expressed as a filter for simplicity; the same applies hereinafter).
  • the cigarette with filter 30 has the same structure as the cigarette with filter shown in FIGS. 1 and 2 except that the structure of the filter 310 is different.
  • the filter 310 has a lower bottom plane 312 that is the same circular plane as the base end surface 112 of the cigarette rod 110, but the inclined surface constitutes a convex curved surface 311.
  • the acute angle ⁇ formed between the longest straight line LB among the straight lines connecting the two points on the contour line of the convex curved surface 311 and the extension line AX of the axis of the cigarette rod 110 has been described with reference to FIGS. 1 and 2. It is the same as ⁇ in the cigarette with filter 10.
  • the distance in the axial direction of the cigarette rod 110 between two points that define the longest straight line LB among the straight lines connecting the two points on the contour line of the convex curved surface 312 (in other words, the axis of the cigarette rod 110 of the filter 310).
  • the maximum length LL in the direction is also the same as d and LL in the cigarette with filter 10 described with reference to FIGS.
  • the cigarette with filter 40 has the same structure as the cigarette with filter shown in FIGS. 1 and 2 except that the structure of the filter 410 is different.
  • the filter 410 has a lower bottom plane 412 that is the same circular plane as the base end surface 112 of the cigarette rod 110, but the inclined surface forms a concave curved surface 411.
  • the acute angle ⁇ formed between the longest straight line LB among the straight lines connecting the two points on the contour line of the concave curved surface 411 and the extension line AX of the axis of the cigarette rod 110 has been described with reference to FIGS. 1 and 2. It is the same as ⁇ in the cigarette with filter 10.
  • the cigarette with a filter according to the present invention has a relatively simple structure and can be easily taken out from a package, particularly a soft package.
