It shows the case of smoking a cigarette.

Hereinafter, embodiments of the cigarette holder according to the present invention will be described in detail with reference to the attached drawings.

[Embodiment 1]
As shown in FIGS. 1 and 2, the cigarette holder sales set G includes a plurality of holder bodies 1 (five in the embodiment) including tar extraction means 6 inside, and a tubular adapter 9. Is a set product consisting of a combination of one cigarette cover and one mouthpiece cover 8. In the packaging case E, five holder bodies 1 each containing the tar extraction means 6, one adapter 9 and one mouthpiece cover 8 are housed and traded.

As shown in FIG. 3, the cigarette holder A has an adapter 9 in the first cigarette insertion portion 2 of the holder main body 1 taken out from the packaging case E shown in FIG. 1, and a mouthpiece cover 8 in the mouthpiece 3. Is attached and used. The adapter 9 has a flange portion 9b that is removable from the tip of the holder body 1 and has a length that can be held by being sandwiched between the fingers of one hand. The flange portion 9b serves as a stopper when inserting the adapter 9 into the first cigarette insertion portion 2, and also makes it easier to pinch the adapter 9 with fingers when inserting and removing the adapter 9 into the holder body 1 and increases the strength. It is also provided to prevent thermal deformation. The holder body 1 is formed with a grip groove 2a on the outer periphery of the first cigarette insertion portion 2 adjacent to the flange portion 9b of the adapter 9 to prevent slipping when held by the fingers of the opposite hand. The user can smoothly pull out the adapter 9 from the holder body 1 by holding the flange portion 9b and the first cigarette insertion portion 2 with one finger and moving them in opposite axial directions. is there. By attaching and detaching the adapter 9 to and from the holder body 1, the cigarette holder A can properly hold and smoke cigarettes of various sizes.

As shown in FIGS. 3 to 5, the cigarette holder A has a first cigarette insertion portion 2, a mouthpiece 3, and a flue 5 that communicates between the first cigarette insertion part 2 and the mouthpiece 3. From the holder body 1 to be held, the tar extraction means 6 including the filter 6a housed in the flue portion of the holder body 1, and the first cigarette insertion part 2 to be detachably inserted into the first cigarette insertion part 2. It is composed of a tubular adapter 9 having a small-diameter small-diameter cigarette insertion portion 9 m and a mouthpiece cover 8 detachably attached to the mouthpiece 3.

As shown in FIGS. 3 and 5, the holder main body 1 is provided with a cylindrical first cigarette insertion portion 2 and substantially flattened portions provided at opposite ends of the first cigarette insertion portion 2 via a step portion 3a. It has a shaped mouthpiece 3.

As shown in FIG. 4, the adapter 9 includes a flange portion 9b that abuts on the first cigarette insertion portion 2 and a tubular portion 9a that forms a small-diameter cigarette insertion portion 9m provided following the flange portion 9b. .. The tubular portion 9a is provided with a constricted portion 9c on the lower end side thereof, and the constricted portion 9c is located at a portion of a step portion 1g provided at the lower end portion of the first cigarette insertion portion 2.

As shown in FIG. 5, the holder body 1 is made of a first resin material, and the adapter 9 is made of a second resin material that is softer than the first resin material. The holder body 1 is made of polystyrene, which is a white thermoplastic resin material, by injection molding, and has a length of about 50 mm. The adapter 9 is made of polyethylene, which is a white thermoplastic resin material, by injection molding and has a length of about 15 mm. Therefore, when the adapter 9 is slid along the holder body 1, there is little change in the catching force and the frictional force, and the slide of the adapter 9 is stable.

As shown in FIG. 5, the flue 5 has a trumpet-shaped cross section in the axial direction when viewed from the front, penetrates the inside of the holder body 1 in the axial direction, and is held by the first cigarette insertion port 4 and the user in the mouth. It communicates with the mouthpiece 3 for smoking.

As shown in FIG. 5, the holder body 1 has a third cylinder portion 1c having a diameter smaller than that of the second cylinder portion 1b on the tip end side of the second cylinder portion 1b, and a cylindrical filter in the third cylinder portion 1c. The tar extraction means 6 made of 6a is frictionally held.

As shown in FIG. 5, the holder main body 1 has a first cylinder portion 1a constituting the first cigarette insertion slot 4 and a second cylinder portion 1b constituting the reduced diameter portion 1e. In the adapter 9, the cylinder portion 9a is slidable in the first cylinder portion 1a, and a friction portion 9d that rubs against the second cylinder portion 1b is provided on the tip end side of the cylinder portion 9a via the constricted portion 9c. .. After the adapter 9 slides freely along the first cylinder portion 1a, the friction portion 9d reaches the second cylinder portion 1b, and the adapter 9 rides on the second cylinder portion 1b over the step portion 1g and rubs against the adapter 9. 9 is held by the holder body 1.

On the lower end side of the outer peripheral surface of the adapter 9, a constricted portion 9c of a concave groove along the circumferential direction and a friction portion 9d of an annular ridge are formed. The friction portion 9d reaches the second cylinder portion 1b and is inside the second cylinder portion 1b without being pressed against the inner peripheral surface of the first cylinder portion 1a as the adapter 9 slides on the tip side of the cylinder portion 9a. It rubs against the peripheral surface. As a result, the difficulty of attachment / detachment due to engagement is alleviated, and the smoothness of attachment / detachment work of the adapter 9 to / from the holder body 1 is ensured.

As shown in FIGS. 3 to 5, the user sandwiches the flange portion 9b with his / her fingers, slides the adapter 9 along the first cylinder portion 1a by a distance E2 = 11 mm, and slides the flange portion 9b into the first cigarette insertion slot 4. Engage in. At this time, the slide is smooth at the first distance E1 = 9 mm when entering the first cigarette insertion slot 4. After that, the friction portion 9d increases and maintains the frictional resistance with respect to the second cylinder portion 1b within a range of about 2 mm until the flange portion 9b engages with the first cigarette insertion port 4. Therefore, the distance that the friction portion 9d rubs against the second cylinder portion 1b after sliding the adapter 9 along the first cylinder portion 1a is 1 mm or more and less than 2 mm.

The friction portion 9d is provided on the tip end side of the tubular portion 9a via a constriction portion 9c, and has a rounded portion 9h having a taper on the tip end side. The constricted portion 9c of the peripheral groove has a smaller diameter than the second cylinder portion 1b, and the annular friction portion 9d has a larger diameter than the second cylinder portion 1b. Further, the axial length of the constricted portion 9c is larger than the radial depth of the constricted portion 9c with respect to the friction portion 9d.

Specifically, as an example, the diameter d2 of the second cylinder portion 1b was set to 7.0 mm, the diameter of the constricted portion 9c was set to D3 = 6.8 mm, and the diameter of the friction portion 9d was set to D2 = 7.2 mm. The diameter d1 of the first cylinder portion 1a was set to 7.9 mm, whereas the diameter of the cylinder portion 9a was set to D1 = 7.8 mm.

As a result, in the cigarette holder A of the first embodiment, when the adapter 9 is attached to the holder body 1, the adapter 9 smoothly slides along the first cylinder portion 1a, and the flange portion 9b is inserted into the first cigarette insertion port 4. Friction is held by increasing the frictional force smoothly before hitting the entrance. This increase in frictional force occurs as the inlet of the second cylinder portion 1b is elastically expanded along the taper of the rounded portion 9h and the diameter of the friction portion 9d is reduced.

On the other hand, when the adapter 9 is removed from the holder body 1, the friction portion 9d smoothly reduces the frictional force with respect to the holder body 1 in the process of sandwiching the flange portion 9b with fingers and separating it from the entrance of the first cigarette insertion port 4. .. This decrease in frictional force occurs as the inlet of the second cylinder portion 1b is expanded along the taper of the rounded portion 9h and the diameter of the friction portion 9d is released. Then, when the flange portion 9b is separated from the inlet of the second cylinder portion 1b, the adapter 9 shifts to a smooth slide with respect to the holder body 1.

Therefore, the adapter 9 can be smoothly inserted and removed from the holder body 1 as compared with the case where the conventional lock structure or suction structure for engaging the protrusion and the recess between the holder body 1 and the adapter 9 is adopted. Therefore, it is difficult to drop the adapter 9 and the holder body 1 to the ground due to the excessive force of the pulling fingers.

As described above, in the first embodiment, the distance at which the friction portion 9d generates frictional resistance is set to 1 mm or more and less than 2 mm. Therefore, the balance between the smooth sliding distance by the tubular portion 9a and the distance accompanied by the frictional resistance of the friction portion 9d when the adapter 9 is attached and detached is sensuously comfortable in the size of the cigarette holder. Eliminates anxiety and low reproducibility due to a large distance with frictional resistance, and alleviates the difficulty of attaching and detaching due to excessive friction between the outer peripheral surface of the adapter 9 and the inner peripheral surface of the first cigarette insertion slot 4. ing. As a result, the adapter 9 can be smoothly attached to and detached from the holder body 1.

By the way, in the cigarette holder A of the first embodiment, the contact of the friction portion 9d with respect to the second cylinder portion 1b functions as a linear seal at the tip of the adapter 9, so that the contact with the first cylinder portion 1a of the holder body 1 It is difficult for tar to enter the gap of the cylinder portion 9a of the adapter 9. As a result, adhesion between the holder body 1 and the adapter 9 due to tar is less likely to occur, and the increase / decrease of the frictional resistance when the adapter 9 is attached / detached becomes more continuous and smooth, and when the adapter 9 is attached / detached. The reproducibility of the response is high. Further, as the adapter 9 is attached / detached, the adapter 9 is less likely to get dirty on the fingers. Since the constricted portion 9c reduces the wall thickness of the cylinder portion 9a of the adapter 9 to reduce the rigidity of the cantilever, the variation in the contact pressure with the second cylinder portion 1b around the friction portion 9d becomes small, and the friction The sealing performance of the part 9d is enhanced.

In the first embodiment, the holder body 1 has a third cylinder portion 1c having a diameter smaller than that of the second cylinder portion 1b. As an example, the first cylinder portion 1a has a diameter d1 = 7.9 mm and a length e1 = 9.0 mm. The second cylinder portion 1b has a diameter d2 = 7.0 mm and a length e2 = 5.0 mm. The third cylinder portion 1c has a diameter d3 = 6.5 mm and a length e3 = 20.0 mm. The third cylinder portion 1c is a part of the flue 5 that connects the first cigarette insertion port 4 and the suction port portion 3. The third cylinder portion 1c houses the tar extraction means 6 composed of a 20.0 mm filter 6a, which is an example of a predetermined length, by frictionally holding the tar extraction means 6 in close contact with the inner peripheral surface of the third cylinder portion 1c. ..

The filter 6a constituting the tar extraction means 6 is a predetermined one in which various natural fibers and synthetic fibers, for example, fibers such as acetylcellose, rayon, and polypropylene are focused in a cylindrical shape, and at the same time, the side surface portions are melted and coated by heat. It is cut appropriately to the length of the fiber, and allows smoke to pass through when smoking to remove harmful components and tar taste in the smoke. The portion of the tar extracting means 6 can be a disk-shaped tar extractant described in Patent Document 1, and in this sense, both are collectively referred to as a tar extracting means.

FIG. 6 is an explanatory view of a modified example of the adapter 9 in the cigarette holder A of the first embodiment shown in FIGS. 1 to 5. The adapter 9B of the modified example is used in place of the adapter 9 of the cigarette holder A of the first embodiment. Therefore, in FIG. 5, members common to the cigarette holder A are designated by the same reference numerals as those in FIGS. 1 to 4, and duplicate description will be omitted.

The adapter 9B of the modified example has a reduced diameter portion 9i that restricts the insertion of the super slim size cigarette 10C at the end of the third cigarette insertion port 9f. With this configuration, the super slim size cigarette 10C inserted into the third cigarette insertion slot 9f abuts against the reduced diameter portion 9i to generate a response, so that the super slim size cigarette 10C is excessive with respect to the third cigarette insertion slot 9f. It is possible to avoid falling due to inadequate insertion or inadequate insertion.

The constricted portion 9k of the adapter 9B of the modified example is a U-shaped groove having a groove width in the axial direction larger than the groove depth with respect to the friction portion 9d. Here, the groove depth is 1/2 of the diameter difference between the friction portion 9d and the constricted portion 9k. The U-shaped groove is a groove having a flat groove bottom having the same depth and a substantially U-shaped cross section. With this configuration, the rigidity of the cantilever beam that supports the friction portion 9d is reduced, so that the adapter 9B can be smoothly attached to and detached from the holder body 1, and the reproducibility of the attachment and detachment of the adapter 9B is improved.

As shown in FIG. 7, a plurality of second cigarette insertion ports 9e and third cigarette insertion ports 9f having different diameters are provided in the small-diameter cigarette insertion portion 9m of the adapter 9. The adapter 9 is used for the holder body 1 when smoking a slim size cigarette 10B (diameter about 7 mm) or a super slim size cigarette 10C (diameter about 5 mm), which is thinner than the commercially available regular size cigarette 10A (diameter about 8 mm). It is attached to the first cigarette insertion slot 4.

As shown in FIG. 7A, when smoking the regular size cigarette 10A, the user directly inserts the regular size cigarette 10A into the first cigarette insertion slot 4 of the holder body 1 of the cigarette holder A. At this time, the insertion end of the regular size cigarette 10A abuts on the step portion 1g transitioning from the first cylinder portion 1a to the second cylinder portion 1b and is stopped. When smoking a commercially available regular-sized cigarette 10A, the user causes the first cylinder portion 1a constituting the first cigarette insertion slot 4 to hold the regular-sized cigarette 10A. The second cylinder portion 1b from which the adapter 9 has been removed is a cigarette insertion port (4b) for inserting and holding a cigarette having a diameter smaller than that of the first cigarette insertion port 4. As a result, the parts of the holder body 1 are shared with the cigarette holder that does not use the adapter 9.

FIG. 7B shows a state in which the adapter 9 is attached to the first cigarette insertion slot 4 of the holder body 1 and the slim size cigarette 10B is inserted into the second cigarette insertion slot 9e of the adapter 9. At this time, the insertion end of the slim-sized cigarette 10B abuts on the step portion 9g transitioning from the second cigarette insertion port 9e to the third cigarette insertion port 9f and stops. When smoking a commercially available slim-sized cigarette 10B, the user inserts and attaches the adapter 9 into the first cigarette insertion slot 4 of the holder body 1. The user holds the slim-sized cigarette 10B in the second cigarette insertion slot 9e of the adapter 9. of

FIG. 7C shows a state in which the adapter 9 is attached to the first cigarette insertion slot 4 of the holder body 1 and the super slim size cigarette 10C is inserted into the third cigarette insertion slot 9f of the adapter 9. At this time, the insertion end of the super slim size cigarette 10C can be inserted until it hits the tar extraction means 6. When smoking a commercially available super slim size cigarette 10C, the user inserts and attaches the adapter 9 into the first cigarette insertion slot 4 of the holder body 1. The user inserts the super slim size cigarette 10C as far as it will go and holds it in the third cigarette insertion slot 9f of the adapter 9.

The present invention is not limited to the above embodiment, for example, the inner diameters of the first to third cigarette insertion ports can be appropriately changed according to changes in the size of commercially available cigarettes, and the outer shapes of the holder body and the adapter are also designed. Various changes can be made from the above viewpoints and the like. Therefore, the present invention includes all modified embodiments that can be easily conceived by those skilled in the art from the above description.

For example, in the first embodiment, the first cylinder portion 1a, the second cylinder portion 1b, and the third cylinder portion 1c are all described as parallel inner cylindrical surfaces. The first cylinder portion 1a constituting the first cigarette insertion port 4 has a cylindrical surface having a constant diameter, and the smooth and rattling slide of the adapter 9 is prioritized. However, in order to facilitate the insertion of the regular size cigarette 10A, the first cigarette insertion port 4 has the entrance side slightly wider than the diameter of the regular size cigarette 10A and the back side of the regular size cigarette 10A. It may be slightly narrower than the diameter to prevent the tobacco from falling out. The inner diameter of the first cylinder portion 1a may be formed so as to gradually narrow from the inlet side to the inner diameter side. In this case, the tubular portion 9a of the adapter 9 may also be formed so that the diameter gradually decreases from the inlet side to the inner side in correspondence with this.

On the other hand, the second cigarette insertion port 9e and the third cigarette insertion port 9f formed in the adapter 9 give priority to the insertion of the cigarette and make the inlet side slightly wider than the outer diameter of the compatible cigarette. It is recommended that the back side be formed so that it is slightly narrower than the outer diameter of the compatible cigarette. A tapered step portion 9 is actually formed between the second cigarette insertion port 9e and the third cigarette insertion port 9f.

Further, in the first embodiment, one constricted portion 9c and one friction portion 9d are provided on the tip end side of the tubular portion 9a of the adapter 9, but the present invention is not limited to this, and a plurality of constricted portions 9c and friction portions 9d are provided. It is also possible to provide it.

Further, since the recovered tar does not adhere to the inside of the adapter 9 and it is not necessary to check the recovery condition of the tar, it is not necessary to use a transparent resin material, and the adapter 9 may be translucent. It may be colored from the viewpoint of the above, and in some cases, it may be made of a metal such as aluminum.

Further, normally, the holder body 1 in which the tar extraction means 6 is housed, the adapter 9, and the mouthpiece cover 8 are sold together, but in that case, the holder in which the tar extraction means 6 is housed is sold. The number of main bodies 1 is, for example, 5 or more as shown in FIGS. 1 and 2, and the number of adapters 9 and mouthpiece covers 8 is less than the number of holder main bodies 1, for example, one by one or the holder main body. It is less than the number. With such a configuration, cost reduction and convenience can be enhanced.

Further, the tar extraction means 6 may add various substances to the fibers focused in a cylindrical shape. Examples of the substance to be added include vitamin C, lactose, enzyme, silica gel, herbal extract, glycyrrhizin, and zeolite. Vitamin C adsorbs 3,4 benzpyrene, which is a harmful substance in smoke, and lactose suppresses the oxidation of this vitamin C. Enzymes remove odors caused by nicotine and tar in smoke and spicy taste in smoke, and silica gel and herb extracts remove harmful substances such as nicotine and tar. Various substances are directly applied to the fibers of the tar extraction means 6 composed of the filter 6a, or adsorbed between the fibers.
