覚部分にしかぶつからないこととなる。Vent means for introducing venting air into the filter are well known in the art, and their purpose is to reduce the total smoke content in the main stream of smoke. When ventilating air enters a filter made of fibrous filter material such as cellulose acetate through ventilation holes at the periphery of the filter, cigarette smoke flows through the axial direction with a diameter smaller than the diameter of the end face of the filter plug. This relatively narrow stream of smoke, which is known to flow out of the filter2, only impinges on the taste perception area of a limited area within the smoker's mouth.
本発明の目的はフィルター使用時に喫煙者の口中の味覚
知覚部分の広い区域に刺戟をおこすような煙草フィルタ

とt%徴とする煙草フィルタープラグするものである。That is, the present invention provides a rod-shaped plug made of a filter material, which has one or more air-conducting tubes around the circumference of the plug, and the one or more air-conducting tubes are located at the suction end of the plug at a position far from the entire suction end of the outlet opening. an inlet opening in the plug, and the one or more air conduit tubes have an area whose depth gradually decreases along the air conduit tube toward the suction end of the plug. It is a cigarette filter plug.

In this case, the groove width may be constant, or may increase or decrease toward the suction end of the filter plug.

5の表面は不透過性にされてよい。The cigarette in Figure 1 is a cigarette vapor 2. (5) A self-shape-retaining filter plug 4 made of cut-out, cut-out, and fibrous cellulose acetate filter material? The periphery of the plug 4 has a large number of parallel filters 5 (8 in the drawing) extending in the axial direction.
Figure 2). As can be seen from FIG. 1, the groove 5 is shorter than the overall length of the plug and is provided from the mouth end of the plug 4, decreasing in depth in the direction of the mouth end of the plug substantially up to the mouth end. It seems like it's going on. A convenient method for forming the grooves 5 is to form a long filter rod from which the plug 4t or preferably several plugs are made using suitable molding means.
765 and the like. #
The surface of 5 may be made impermeable.
フィルター3全シガレツトロツド1,2に取シ付けるた

分では蒋5の壁部と共に空気導通f 8 km成する。A tip material 7 is used for attaching the filter 3 to the cigarette rods 1 and 2, which forms an air connection f 8 km with the wall of the rod 5 at the base of m5.

The plug 4 is wound around the upstream end of #5 at a position (6), so that each air conductor 'R8 communicates with one or more ventilation holes 9.

度成分となる。When the cigarette of FIG. The air passes through the conduit 8'Ik and exits without mixing with the cigarette smoke, essentially without mixing. The groove 5 constituting a part of the air conduit f8 has a depth that decreases in the direction of the air flow along the conduit 8, so that the air can flow through the conduit 8.
When it exits the smoker's mouth and enters the smoker's mouth, it becomes a velocity component that moves outward in a circular manner.

性の同上として受けとられる。In this way, due to the Coanda effect, a shunt of air is formed with the air flowing out from the mouth end of the filter plug 4, and as a result, the smoke hits a relatively wide area of the taste 5 in the smoker's mouth. For smokers, this is perceived as the same characteristic of smoke.
第3図にその吸口端を示したフィルターは多数の長さ方
向の周縁溝の代シに1個だけの環状周縁溝57會有する
プラグ4′からなりている。プラグ4′の軸方向断面は
第1図のプラグ4の溝5の場合と同様の外形を有する。The filter, the mouth end of which is shown in FIG. 3, consists of a plug 4' having only one annular circumferential groove 57 instead of a plurality of longitudinal circumferential grooves. The axial cross-section of the plug 4' has a contour similar to that of the groove 5 of the plug 4 in FIG.

7′は強度の高いものでなければならない。A strong outer collar or mouthpiece 7' made of plastic material or the like accommodates the plug 4', and the cigarette rod end is inserted in the same manner as the cigarette tipping 7 in FIG. The outer tube 7' must be of high strength so that the annular suction opening of the air passage tube 8' indicated by 6, which is constituted by the annular m5' and the outer f7', does not close when the filter is in use. It won't happen.
第3図のフィルターによって得られる効果は第1及び2
図のフィルター3のものと同様である。The effects obtained by the filter in Figure 3 are as follows:
It is similar to that of filter 3 in the figure.

。When the ambient air is drawn into the air conduit 'u8 through the through hole (not shown) in the wrapper or mouth piece 7', the I#5'
This is because the shape of the smoker creates a shunt of air that enters the smoker's mouth, causing the smoke to impinge on a wide range of taste-sensing areas.

It can be used in place of the axially extending groove of the filter of FIG. 1 or the single annular groove 5' of the filter of FIG. In FIG. 4, numeral 10 indicates the suction end of the filter plug 11. The first set has peripheral edges 13 that are slightly offset from the axial direction of the plug 11, and the second set of springs 14 are offset in the opposite direction by the same angle. These two sets of continuous rods 13 and 14 intersect to form a complete network structure.

合と同様にして達成される。As in the case of a single type of groove 5, the grooves 13, 14 each have a region 1 which decreases in depth in the direction of the mouth end IO of the plug 11 substantially to its end. In use, the plug 11 is superimposed by a wrapper (not shown) which allows ambient air to be introduced into the groove from a point upstream of the groove 13.14, the smoke diffusion effect being achieved in a manner similar to that of the filters already described. be done.

。The filter plug pouch and pinning means are composed of a permeable plug wrapper on the outer periphery of the plug and an impermeable long tip material overlaid on the plug wrapper and fixed to the filter plug' (+- tobacco rod 2). In this case, the ventilation holes are simply housed in the impermeable chip material.
