"Conventional Technical Background and Problems Therein" In recent years, individual preferences regarding cigarettes have diversified, and various brands of filtered cigarettes with variable taste have been developed. For example, a typical example of such filtered cigarettes is:
One example is a filter chip in which small holes are formed at equal intervals in the circumferential direction on the outer circumferential surface of the filter tip. In this cigarette with small holes, when smoking, air can be introduced into the filter tip through the small holes, so this introduced air dilutes the smoke flow flowing inside the filter tip, which allows the smoker to moderately smoke the smoke. You can inhale diluted and light cigarette smoke.

By the way, as mentioned above, it goes without saying that there are differences in the degree of preference between individuals regarding the light taste of smoking, but each individual may also change the taste of cigarettes depending on the time and situation. There's something I want to taste.

However, since the cigarettes that each individual purchases are usually of a fixed brand, the level of flavor that this brand of cigarette has is always the same; It is virtually impossible to enjoy tobacco by changing it.

For this reason, there is a desire for a filter-equipped cigarette that can vary the taste of each brand of tobacco, and various proposals have been made to obtain such filter-equipped cigarettes. However, the manufacturing cost was high and it was not suitable for mass production, and could not be put to practical use.

``Embodiment of the Invention'' A filter-equipped cigarette according to an embodiment of the invention will be described below with reference to FIGS. 1 to 3.

1 in FIG. 1 is a filter chip. This filter chip 1 is formed by wrapping a plug paper ring 3 around a rod-shaped filter material 2 made of a fiber material such as cellulose acetate or polypropylene.

A cigarette main body 5 is arranged in series at the end opposite to the mouth end of the filter tip 1, and the filter tip 1 and the cigarette main body 5
and are mutually connected by a connecting ring 6.
The connecting ring 6 is formed by wrapping and gluing a piece of non-breathable paper chip paper from the other end of the filter tip 1 to the cigarette body 5. A tip ring 7 made of tip paper is also wrapped around and glued to the suction end of the filter tip 1 with a predetermined gap between it and the connecting ring 6.

A ventilation portion 8 is provided in a portion of the filter tip 1 exposed to the outside between the tip ring 7 and the connection ring 6, as shown in FIGS. 2 and 3. In the case of this embodiment, the ventilation section 8 is constructed by forming a large number of small holes 9 in a portion of the outer peripheral surface of the filter chip 1 close to the connecting ring 6, that is, in the plug paper 3. The formed annular region has a predetermined width in the axial direction of the filter chip 1.

Further, an adjustment ring 10 made of tip paper is fitted from the outside to a portion of the filter tip 1 exposed between the tip ring 7 and the connection ring 6. The adjustment ring 10 has a width in the axial direction that can sufficiently cover the annular region in which the small hole 9 is formed, and is capable of sliding on the outer peripheral surface of the filter tip 1 in the axial direction. There is.

According to the above-mentioned filtered cigarette, when the cigarette is smoked in the state shown in FIG. As shown by the solid arrow in FIG. 2, the smoke flows from the cigarette body 5 through the filter material 2 of the filter tip 1 to its mouth end, and from this mouth end only smoke flows into the smoker's mouth. do. Therefore, in this case, the smoker can enjoy a relatively heavy smoking taste.

On the other hand, as shown in FIG. 3, the adjustment ring 10 is slid and positioned toward the tip ring 7, and smoking is thereby performed with the entire annular region of the small hole 9 exposed to the outside, as described above. Naturally, the smoke flows from the cigarette body 5 through the filter material 2 to the mouthpiece end, and from this mouthpiece end into the smoker's mouth, but in this case, as shown by the broken line in FIG. In addition, since the air introduced from each small hole 9 flows into the filter tip 1, it is possible not only to suppress the amount of smoke flowing into the smoker's mouth, but also to reduce the amount of smoke that enters the smoker's mouth.
Inside, the smoke stream is diluted with air, giving the smoker a light tasting experience.

Furthermore, as is already clear from the above description, by adjusting the axial position of the adjustment ring 10,
By varying the exposed area of the small holes 9 that are exposed to the outside, the amount of smoke flow and the amount of air that enters the smoker's mouth can be arbitrarily changed, so the smoker can change the taste from light to heavy. You can enjoy the gradual taste sensation up to the tasteful taste.

Incidentally, since the adjustment ring 10 is positioned between the connection ring 6 and the tip ring 7, these rings 6 and 7 function as a stopper for the adjustment ring 10, and can prevent the adjustment ring 10 from falling off from the cigarette. It also has advantages.
