Description of the invention: * [Technical field to which the invention pertains] 4 The present invention relates to a cigarette with a filter, and more particularly to a cigarette with a filter that is easily taken out of the package. [Prior Art] A cigarette with a filter is stored in a package so that the filter is placed on the open end side when the package is unsealed. When smoking cigarettes, the purchased cigarette package is opened, and the i-th cigarette is caught by fingers or nails and taken out. However, since the cigarette with the filter is tightly packed in the package, it may be difficult to take out particularly in the case of a package, or it must be taken out with a strong force to deform the filter. Some smokers will tap the package to make the cigarette protrude from the package and then take it out with a finger and take it out. Some smokers find it difficult to take out the cigarette after the second root after taking out the first cigarette. In order to facilitate the removal of the cigarettes stored in the package, in the patent literature, a technique of providing a gripper protruding from the filter in the filter is proposed. (Prior Art Document) (Patent Document) Patent Document 1: Japanese Laid-Open Patent Publication No. SHO-50-112798 (Summary of the Invention) The object of the present invention is to provide a structure that is easy to remove from a relatively simple structure. Remove the cigarette with the filter. (Means for Solving the Problem) 201201718 According to one aspect of the present invention, the system has a cylindrical scent; == has an end surface; and a slab, and the front end surface and the circular base are connected to form a face bar. In the above-described cigarette holder, the bottom surface of the cigarette rod and the end surface of the cigarette rod are similarly rounded and have a cylindrical shape, and the inclined surface inclined on the long line is inclined (the effect of the invention). The bottom surface is connected to the cigarette rod. The scent of the filter with the filter of the present invention can be easily taken out from the package (especially the flexible package) with a relatively simple structure. [Embodiment] The aspect of the present invention will be described with respect to the ruler and the field. The aspect of the present invention is the same as that of the cigarette of the present invention, except that the structure is different from that of the structure. The cigarette of the scented cannon a filter has: round 枉 face) nt: has a round front end face (planar) and a circular base end face (the beauty of the fate / device, connected to the cigarette rod. The filter system is formed a chamfered cylindrical shape having a circular bottom surface (planar surface) and a sloped surface inclined with respect to an extension line of the axis of the cigarette rod: the device is attached to the cigarette rod at the lower bottom surface The base end face. "(4) Contains: The structure obtained by cutting the cylinder with respect to the axis of _ (on the extension line of the cigarette rod) (with the center axis of the filter, the instrument, and the plane inclined at an angle of (10) degrees. ς = The above plane of the cut cylinder does not cut the bottom surface of the cylinder. The bottom surface above the circle can be cut or not cut. When the above _ plane 322887 4 201201718 does not cut the top surface of the cylinder When the cut cylinder is a so-called chamfered cylinder, in the chamfered cylinder, the inclined surface is a plane of an elliptical shape. When the cutting plane cuts the upper surface of the cylinder, the resulting chamfered cylinder Upper surface and bottom surface The circular arc plane of the row and the elliptical arc plane having the inclination of the chord common to the arc of the arc of the arc plane. The elliptical arc system forms a line symmetry with respect to the long axis of the ellipse including the elliptical arc. In the case of the case, the inclined plane of the filter generally intersects the extension line of the axis of the cigarette rod. In the present invention, the beveled cylinder includes a case where the inclined surface is a curved surface. That is, the inclined elliptical surface is not a flat surface. However, a convex curved surface or a concave curved surface is formed. Here, the convex curved surface or the concave curved surface is a straight line connecting the two points of the specified maximum length and the cigarette rod in a straight line connecting the two points on the contour line of the convex curved surface or the concave curved surface. The present invention will be described with reference to the drawings. The same elements are denoted by the same reference numerals throughout the drawings, and the description thereof will be omitted. FIG. 1 shows the first aspect of the present invention. A perspective view of the cigarette 10 with a filter, and Fig. 2 is a side view of the cigarette 10 with a filter. The cigarette 10 with a filter is provided with a general cigarette filled with a cigarette paper wrapped with a general cigarette paper. material The cigarette rod 110 is formed by the outer circumference of the cylindrical rod. The cigarette rod 110 has a front end surface 111 and a base end surface 112, and the front end surface 111 and the base end surface 112 are of course circular planes. The cigarette rod 110 is similar to a general cigarette. The length of 49 mm to 68 mm and the diameter of 7.2 to 8.3 mm. At the base end face 112 of the cigarette rod 110, the filter 120 is attached by the same layer of paper 130 as the cigarette with the filter 5 322887 201201718. The filter 120 is composed of a filter body composed of, for example, a bundle of cellulose acetate fibers, and a forming paper covering the filter body. The filter 120 is in the shape of a chamfered cylinder. That is, the filter 120 is a system. An inclined plane 121 having an elliptical shape and a bottom surface 122 having a circular shape similar to the front end of the cigarette rod ι10. The slanted plane 121 of the ellipse is intersected with the axis of the cylinder (the extension of the axis AX of the cigarette rod 110). The lower surface 122 of the filter 120 abuts against the base end surface 112 of the tobacco rod 110. As with the conventional cigarette with a filter, the outer layer 130 covers the outer periphery of the cigarette rod 110 and the filter 120 from the base end portion of the cigarette rod no to the upper end of the filter 120. The diameter of the filter 120 is the same as the diameter of the tobacco rod 110. As described above, the cigarette rod 110 and the filter 120 are connected by the outer layer paper 130, but the diameter of the filter 120 does not include the thickness of the outer layer paper 130 (usually 40/m). Referring to Fig. 2, from the cigarette The acute angle 0 formed between the elliptical inclined plane 121 and the extension line of the axis AX of the cigarette rod no is preferably larger than 28 degrees and less than 72 from the viewpoint of ease of taking out (easiness of grasping with a finger). The degree is more preferably greater than 28 degrees and less than 58 degrees. Further, the filter 120 which defines the long axis of the ellipse of the inclined plane 121 (correctly, although it is the outer layer paper 130, but is shown as a filter for convenience, the same applies hereinafter), among the two points on the outer peripheral surface, 5毫米。 The distance of the cigarette rod 11 〇 轴 ( ( ( 香烟 香烟 香烟 香烟 2 2 2 2 2 2 2 2 2 mm mm mm mm mm mm mm mm mm mm mm mm mm mm mm mm mm mm Large and smaller than 12. Smaller, more preferably 5. 0 to 5_. The maximum length LL of the filter 120 in the axial direction of the cigarette 322887 6 201201718 is generally 18 25 mils to 36.25 mm. Further, at two points on the outer circumferential surface of the damper 120 of the ellipse having the long axis of the slanting plane 121, two points of the longest straight line among the two points _ straight lines on the slanting plane 121 are also connected. A cigarette with a filter shown in Figs. 1 and 2 is a double length of a filter which is manufactured by a conventional method, for example, by attaching a cigarette rod to a cigarette with a filter attached to the filter. After the cigarette connecting body at both ends of the filter member, it is placed on the circumferential surface of the circular hammer-shaped cutting cylinder and pushes the round knife toward the filter member in a direction perpendicular to the axis of the cutting cylinder, whereby one can be used. The cigarette connector simultaneously manufactures two cigarettes with filters. Fig. 3 is a perspective view showing a cigarette 2 with a filter attached to a second aspect of the present invention. Figure 4 is a side view of a cigarette 2 with a filter attached. The cigarette 20 with the filter has the same structure as the cigarette with the filter shown in Figs. 1 and 2 except for the structure of the filter 120. The filter 210 has a beveled cylindrical structure that cuts the cylinder in a plane that cuts the upper bottom surface. That is, the filter 21 has a lower end surface 213 which is circular as the base end surface 112 of the tobacco rod 110 corresponding to the lower surface of the cylinder. The upper end surface of the filter 210 is constituted by a circular arc plane 2 ι which is parallel to the lower end surface 213, and a slanted elliptical arc plane 212 having a chord which is common to the arc 211a of the circular arc plane 211. The elliptical arc plane 212 is line symmetrical with the long axis LA of the ellipse of the elliptical arc plane 212 of the packet 3. The round fox plane 211 is crossed with the axis of the cylinder (an extension of the axis of the cigarette rod 11〇). An acute angle formed between the oblique arc elliptical arc plane 212 and the axis of the cigarette rod ho 322887 7 201201718 (9 series can be compared with the cigarette 10 with the filter described with reference to Figs. 1 and 2; The sharp angle 0 is the same. Further, the difference 21 between the maximum length and the minimum length of the filter 21 in the axial direction of the cigarette rod 110 may be the same as that of the cigarette with the filter described in the first and second figures. The difference d in the middle is the same, and the maximum length LL' of the filter 210 in the axial direction of the cigarette rod no can be the same as the LL of the cigarette 10 with the filter described with reference to Figs. 1 and 2. The elliptical arc plane 212 - in the circular fox plane 211 forming the upper end surface of the filter 210, passes through the length from the chord 211a to the arc of the line including the center of the circle of the arc and straight to the chord 211a Preferably, the cigarette having the filter is 10% to the radius of the circle, and the cigarette with the filter shown in Figs. 3 and 4 is obtained after the cigarette with the filter shown in Figs. 1 and 2 is obtained. It can be manufactured by cutting the front end of the filter device in a direction perpendicular to the axis of the cigarette rod. 5 is a side view partially showing a cigarette 30 with a filter attached to a third aspect of the present invention. Fig. 6 is a perspective view partially showing a cigarette 30 with a filter attached. The filter 310 has the same structure as the cigarette with the filter shown in Fig. 1 and Fig. 2 except that the structure of the filter 310 is different. The filter 310 has a circular plane similar to the base end face 112 of the cigarette rod 1010. The lower plane 312 is formed, but the inclined surface constitutes a convex curved surface 311. The acute straight line formed by the longest straight line LB of the straight line connecting the two points on the contour line of the convex curved surface 311 and the axis of the cigarette rod 11〇 is formed. The β-system is the same as the acute angle 0 in the filter-attached cigarette 1 〇 8 322887 201201718 described with reference to Figs. 1 and 2, and is defined as a line between two points on the contour line connecting the convex curved surfaces 311. The distance in the axial direction of the cigarette rod 110 between the two points of the longest straight line LB (in other words, the maximum length LL of the filter 310 in the axial direction of the cigarette rod 11) may be as described with reference to FIGS. 1 and 2 The d and LL in the cigarette 1 with the filter are the same. 7 is a side view partially showing a cigarette 40 with a filter according to a fourth aspect of the present invention. Fig. 8 is a perspective view partially showing the cigarette 40 with a filter attached. The structure of the filter 410 is the same as that of the cigarette with the filter shown in Fig. 1 and Fig. 2. The filter 410 has a circular plane similar to the base end face ι12 of the cigarette rod 11〇. The lower bottom plane 412, but the inclined surface forms a concave curved surface 411. The acute line formed by the longest straight line LB of the straight line connecting the two points on the contour line of the concave curved surface 411 and the extension line of the axis AX of the cigarette rod 11〇 It is the same as the acute angle Θ of the cigarette with the filter described with reference to Figs. 1 and 2 . Further, the distance in the axial direction of the cigarette rod 11〇 between the two points of the longest straight line LB among the straight lines connecting the two points on the contour line of the concave curved surface 412 is defined (in other words, the filter 410 is in the axial direction of the cigarette rod 110). The maximum length LL) ' may be the same as d and LL in the cigarette 10 with the filter described with reference to Figs. 1 and 2 . The filter-attached cigarettes shown in Figures 5 and 6 and 7 and 8 are capable of cutting the filter member by laser after obtaining the previously described cigarette connector. Made in a curved shape. A cigarette with a filter shown in Figs. 5 and 6 and 9 322887 201201718 and a cigarette with a filter shown in Figs. 7 and 8 can be obtained from one cigarette connector. The cigarette with the filter according to one aspect of the present invention described above is housed in the package in the same manner as a general cigarette. In the package, the cigarette with the filter is received in such a way that the filter is located on the unsealed side of the package. Preferably, the cigarettes to which the transition device is attached in the package are preferably arranged such that the inclined faces of the filter are parallel to each other. Fig. 9 is a schematic front view showing a cigarette package 50 in which a plurality of (e.g., 20) cigarettes with a filter shown in Figs. 1 and 2 are accommodated in a flexible package 510. The cigarette pack 50 is the same as a general cigarette pack except that the cigarette with the filter accommodated therein is the product of the present invention. That is, the flexible package 510 is the same as a general flexible package, and includes, for example, a box-shaped outer side flexible package 511. In the outer flexible package 511, 20 cigarettes 10 with filters attached to the inner side flexible package 512 made of aluminum foil as the backing paper were tightly packed and housed. The flexible package 510 is sealed from the top surface to the front and back sides by a sealing paper 513. Usually, the package 510 is generally covered with a resin film (not shown). From the viewpoint of easiness of taking out from the package, the scented cigarette 10 is preferably housed in the package so that the inclined faces 121 of the filter 120 are parallel to each other as shown in Fig. 9. (Embodiment) Example 1 As shown in Table 1, the various inclination angles 0 of the inclined surface 121 and the difference d between the maximum length of the filter 120 in the axial direction of the cigarette rod 110 and the minimum length of 10 322887 201201718 were prepared to have A filter-attached cigarette constructed in the same manner as the cigarette with the instrument shown in Figs. 1 and 2. 9毫米。 The length of the cigarette rod 11 为 is 59mm' diameter of 7. 9mm. Further, the length of the filter 12 is 25 沿着 along its central axis. The cigarette rod 11 is connected to the transition piece 12 by a thickness of sm/zm. A cigarette to which a filter of 2 () of the same structure is attached is stored in a flexible package 510 as shown in Fig. 9, and sealed with a sealing paper to form a cigarette package 50. For each of the cigarette packages produced, a plurality of participants were consulted to investigate the easiness of taking out the first cigarette (the ease of grasping with a finger), and the ease of smoking when smoking cigarettes. The results are shown below. Table 1 〇 Table 1: d(mm) 0 〇1- 90 Grab the ease of taking the reference.

The slanting angle (9 is preferably greater than 28 degrees and less than 11 322887 201201718 75 degrees. In addition, it is better that the d is larger than the 2.5 legs and less than 12. 5mm. As described in detail above, the filter-attached cigarette of the present invention is easily taken out from the package (especially the flexible package) in a relatively simple configuration.
