A control opening is provided on the circumferential surface of the filter to control the entry of external air into the additive in the filter.

  A smoking material rod 100 such as a cigarette includes a smoking material rod 200 and a filter 300. In FIG. 1, the smoking material rod 200 includes a substantially cylindrical tobacco material 210, such as a mixture of chopped tobacco and recycled tobacco, and a wrapper 220 that forms the circumferential surface of the rod 200. Examples of the wrapper 220 include paper known in the industry.

  FIG. 2 shows a filter 300 including a substantially cylindrical filter material plug 310 and a plug paper 320 wound around the circumferential surface of the filter material plug 310. The filter material 310 may contain cellulose acetate tow. Plug paper 320 may include paper for plug paper and may be porous to facilitate ventilation of filter material 310. The diameter of the filter 300 is substantially equal to the diameter of the smokable rod 200. The plug paper 320 is held at a predetermined position around the filter material 310 by being glued along the overlapping seam.

  In FIG. 3, the smoking material rod 200 and the filter 300 are coaxially joined to each other. More specifically, the end surface of the filter 300 comes into contact with the end surface of the smoking material rod 200, so that the smoke sucked from the rod 200 directly enters the filter 300. The rod 200 and the filter 300 are held together by a piece of chipping material 400 made of sheet-like chipping paper, for example, which is superimposed on the joint between the rod 200 and the filter 300. The chipping material 400 may be adhered to the circumferential surfaces of both the rod 200 and the plug paper 320 using a suitable adhesive such as a PVA material. The chipping material 400 may extend substantially along the entire length of the filter 300 and up to about one-tenth of the smoking material rod 200. The chipping material 400 may be substantially non-porous, but may be perforated at a position overlapping the filter material 320 to facilitate ventilation of the filter 300. For example, the chipping material 400 may include a plurality of holes extending in a ring shape around the chipping material 400, and a plurality of corresponding air channels may be provided between the outside of the smoking article 100 and the filter 300 (not shown in FIG. 3). .

  Filter material plug 310 may include at least one indentation or recess, such as one, two, three, four, five, or six indentations or recesses. This is illustrated in FIGS. 4 to 6, each indentation or recess constitutes a groove on the outer surface of the filter material 310. As shown in FIG. 5, the groove extends in the axial direction along the filter from the suction end of the filter 300. The contour line of the groove is substantially perpendicular to the mouth end face of the filter 300. Further features of this indentation or recess will be described below in the description of this groove. However, it should be noted here that it is not essential to form the indentations or recesses in a groove shape, and it is possible to use indentations or recesses of different shapes. Thus, it will be appreciated that the features described below apply to all indentations or recesses, including those that are not groove-shaped.

  The length and depth of the groove are selected according to the desired volume inside the groove (ie formed by a virtual surface extending across the groove and the open end of the groove at the circumferential edge of the filter material 310). volume). However, by way of example, the groove may extend axially along about 3/4 of the length of the filter 300 from the mouth end toward the smok rod 200, and is about half the depth of the filter 300 radius. You may have. The grooves may have a substantially triangular cross-section so that each groove extends deeper into the filter 300. This is illustrated in FIGS. However, it will be appreciated that the cross-sectional shape of the groove may be rectangular, semi-circular or any other suitable shape.

  Filter 300 may also include a liner 340. The inner surface of the groove may be lined with a liner 340 composed of a sheet-like lining material configured to fit the groove. This is clearly shown in FIG. When inserted into the groove, the liner 340 substantially covers the entire inner surface of the groove. More specifically, the liner 340 includes first and second substantially rectangular side surfaces and a substantially triangular end surface. The longitudinal edge of the first side surface is joined to the second longitudinal edge by, for example, bending a sheet-like lining material. The joint portion on the side surface of the liner 340 is located at the base of the groove, and the first and second side surfaces of the liner 340 extend outward from the joint portion to cover the inner surface extending in the axial direction of the groove. The end face of the liner 340 is located relative to the substantially triangular inner end face of the groove 340 extending across the horizontal axis of the filter 300. The opposite end of the liner 340 at the mouth end of the filter 300 may remain open, thereby allowing gas and / or smoke to exit from the open end of the groove 340 at the mouth end of the filter 300. . All that has been described here is shown in FIG.

  The liner 340 may be non-porous to prevent gas movement between the filter material 310 and the interior of the groove. As described above, the mouth end of the groove may be open, thereby allowing gas to move between the inside of the groove and the outside of the filter 300.

  The filter 300 may also include an additive material 350 that affects these parameters as gas or smoke passes through the filter 300. The additive material 350 may include, for example, a flavoring material 350 for flavoring the external air sucked into the filter 300 through the opening 410 of the chipping material 400. More specifically, additive material 350 includes basil, mint, citrus, bay leaf, cardamom, cumin, oregano, paprika, rosemary, saffron, thyme tea, eucalyptus oil, lemon, perilla, turmeric, turmeric root, cilantro, Particulate flavoring or other flavoring agents such as plant-based flavoring agents including or derived from rose, tobacco, orange blossom may be included. Mint flavors may be selected from the following mint species: corn mint, grapefruit mint, Egyptian mint, peppermint, eau de cologne mint, black peppermint, curly mint, kentucky spearmint, silver mint, pineapple mint, penny royal mint, scotch Mint and apple mint. Other flavors include extracts (e.g., licorice, hydrangea, oakashiwa (Japanese bark magnesium leaf), camomil, fenugreek, clove, menthol, mint, anise fruit, cinnamon, herb, winter green, cherry, berry, peach, Apple, Drambuy, Bourbon, Scotch, Whiskey, Spearmint, Peppermint, Lavender, Celery, Cascarilla, Nutmeg, Sandalwood, Bergamot, Geranium, Honey Extract, Rose Oil, Vanilla, Lemon Oil, Orange Oil, Cassia, Caraway, Cognac, Jasmine , Ylang ylang, sage, fennel, pimento, ginger, anise, coriander, mint oil from any species of coffee and mint group), flavored mackerel King agents, bitterness receptor site blockers, receptor site enhancers, sweeteners (eg sucralose, acesulfame potassium, aspartame, saccharine, cyclamate, lactose, sucrose, glucose, fructose, sorbitol or mannitol) and chlorophylls, minerals , Other additives such as plants or breath deodorants. These may be imitation, synthetic or natural ingredients and may be blends thereof.

  The additive material 350 may be composed of, for example, filter tow (for example, cellulose acetate tow) as a base material containing one or more of the above flavoring agents or other additives in a dispersed state.

  The additive material 350 may be positioned in the groove so as to fill the inside of the groove, for example. More specifically, the additive material 350 is disposed on the opposite side of the liner 340 from the filter material 310 to prevent the filter material 310 and the additive material 350 from contacting each other directly. Additive material 350 is comprised of a block of additive material 350 having a shape and dimensions corresponding to the internal shape and dimensions of the groove. In the example shown in FIGS. 4, 5 and 6, additive material 350 is substantially composed of a triangular prism having dimensions corresponding to the internal dimensions of the groove of filter 300. As a result, the additive material 350 is inserted into the groove. When additive material 350 is inserted into the groove, one face of the triangular prism substantially contacts the circumferential surface of the plug of filter material 310 on either side of the groove, thereby causing filter 300 to be substantially circular. It has a cross-sectional shape. Liner 340 may be impermeable to these materials so that filter material 310 and additive material 350 do not mix.

  Optionally, the liner 340 may include a slit 341 on the first or second side described above. The slit 341 may extend in the axial direction from the mouth end of the liner 340. This is illustrated in FIG. By the slit 341, the additive material and the filter material are in direct contact with each other to some extent. In addition or separately, the slit 341 may move the gas between the inside of the groove and the filter material 310. Therefore, as a matter of course, the gas is moved between the additive material 350 and the filter material 310 in the groove.

  As shown in FIG. 4, the surface shape of the plug paper 320 follows the surface shape of the filter material 310 including the surface shape of one or more grooves. Accordingly, the plug paper 320 is located between the filter 310 and the liner 340 inside the groove. This means that the plug paper 320 is in direct contact with all the axially extending surfaces of the filter material 310 including all of the inner surfaces of the one or more grooves. Therefore, the chipping material 400 outside the smoking article 100 is in direct contact with the plug paper 320 where there is no groove, and is in direct contact with the liner 340 and the additive material 350 where there is a groove. This is clearly shown in FIG.

  In FIG. 6, the plug paper 320 may be wound only around the outer periphery of the filter material 310, thereby contacting the filter material 310 only where there is no groove. Where there is a groove, the plug paper 320 extends directly across the top of the groove, thereby contacting the outer surface of the liner 340 and the block of additive material 350. Therefore, in this example, the chipping material 400 simply overlaps the plug paper 320.

  Of course, as shown in FIGS. 4-7, the end of the groove is open at the mouth end of the filter 300, so that the gas is substantially separated from the rod 200 via the groove and additive material 350. To the axial direction and exit the filter 300 at the mouth end of the groove. In the case where the above-described slit 341 is provided in the liner, further gas exits the filter through the suction end surface of the filter material 310 by entering the filter material 310 from the additive material 350 via the slit 341. Is possible.

  External air is drawn into the groove through the opening 410 of the chipping material 400. The opening 410 forms an air channel through the opening 410 and is located at a point on the circumferential surface of the chipping material 400 radially outward from the position of the groove. This is illustrated in FIG. More specifically, a radial line extending from the center of the substantially cylindrical filter 300 passes through both the groove and the opening 410. Accordingly, the external air enters the groove directly through the opening 410 (see FIG. 4) or enters the groove through a porous plug paper 320 positioned between the tipping material 400 and the additive material 350 (see FIG. 4). 6). Alternatively, external air enters the groove through the opening 410 in the chipping material 400 and through one or more holes or perforations in the plug paper 320 located between the chipping material 400 and the additive material 350. . External air is flavored by the additive material 350 in the groove when the external air is drawn toward the suction end of the filter 300 by suction applied at the suction end of the filter 300. Thereafter, the air exits from the mouth end of the filter through the mouth end of the groove or through the slit 341 of the liner 340 and through the end face of the filter material 310. The opening 410, the groove and the additive material 350 together constitute a ventilation path for the filter 300, through which external air is drawn and affects the flavor of the gas flow exiting from the mouth end of the filter 300.

  The chipping material 400 includes an opening 410 for each groove of the filter 300. Each opening 410 is located radially outward from a different groove. For example, the plurality of openings 410 are provided in a belt shape extending in the circumferential direction around the chipping material 400 so that each of the openings 410 is radially aligned with one of the grooves. 3-6 illustrate the filter 300 as including three grooves and corresponding three openings 410 in the chipping material 400. These grooves are located at substantially equal intervals on the circumference of the filter 300, but this is not important. Therefore, the interval between the grooves may not be equal. Furthermore, more or fewer grooves may be provided. Each of the plurality of grooves is filled with the additive material 350 as described above. For example, each groove may include a different additive material 350. These different additive materials 350 may include different flavors 350 so that external air that has entered the first groove through the first opening 410 is passed through the second opening 410. The external air entering the second groove is flavored differently, and the external air entering the second groove is flavored differently from the external air entering the third groove via the third opening 410. The In the example shown in FIGS. 4-7, the filter 300 includes three different flavoring materials 350 provided in three different grooves, which are made available through three different openings 410.

  In FIG. 7, the filter 300 includes a controller 500 for controlling the external air flowing through the one or more openings 410 in the chipping material 400, thereby adding one or more grooves and an additive material 350 inside the grooves. Controls the flow of external air into the interior. By controlling the flow of external air into the groove, it will be appreciated that the controller 500 can affect the taste of the gas flow exiting the mouth end of the filter 300. For example, the controller 500 may be directed to a path of external air through one of the flavor materials 350 such that external air is drawn through the openings 410 in the chipping material 400 and through the flavor material 350 in the groove. If the configuration is open, a flavored gas stream exits through the mouth end of the filter 300. An example of the opening configuration of the control device for one of the flavorant materials 350 is shown in FIG. On the other hand, when the control device 500 has a closed configuration that closes the opening 410 of the chipping material 400 corresponding to the path through the flavor material 350 and prevents external air from being sucked into the groove, the suction mouth of the filter 300 The gas stream exiting the end is not flavored by the flavor material 350 in the groove.

  As shown in FIG. 7, the controller 500 is comprised of a substantially cylindrical ring 500 that opens and closes to the air path through the flavor 350 (or other additive) material. It can be rotated relative to the circumferential surface of the filter 300 so as to take an arrangement. Ring 500 overlaps each circumferentially spaced opening 410 of chipping material 400 and air channel through ring 500 for allowing air to pass through additive material 350 through ring 500. One or more openings 510 that provide Ring 500 includes a ring seal 520 located on its inwardly facing circumferential surface. The ring seal 520 substantially hermetically seals between its inwardly facing surface and the outer circumferential surface of the chipping material 400, so that external air can pass through one or more openings 510 in the ring 500. Preventing entry into one or more openings of the chipping material 400 by a route other than the route through the. In addition, an opening seal 530 is provided around one or more openings 510 provided in the ring 500. The seals 520, 530 may be formed by using a continuous layer of rubber or other suitable material on the inwardly facing circumferential surface of the ring 500. Alternatively, the seals 520, 530 may be formed as beads of rubber or other suitable material disposed at the edge of the circumferential surface facing the inward of the ring 500.

  Furthermore, one or more openings 510 of the ring 500 may be pre-sealed with a plastic seal that is removed during use. This is to prevent unnecessary entry of external air into the additive material 350 before the smoking article 100 is used.

  The ring 500 can be rotated to move its one or more openings to align with the one or more openings of the chipping material 400. This constitutes an open arrangement of the ring that allows external air to be drawn into the one or more grooves through the openings 500, 410 of the ring 500 and tipping material 400. The ring 500 can also be rotated to move its one or more openings to shift its position from the one or more openings of the chipping material 400. This constitutes a closed arrangement of rings that prevents outside air from entering the groove by blocking the tipping material 400 from entering the opening 410. The smoking article 100 is provided to the user with the ring in a closed configuration to prevent unnecessary entry of external air into the additive material 350 prior to use.

  Optionally, the ring 500 may cooperate with one or more guiding means on the outer surface of the filter 300 to limit or prevent longitudinal movement of the ring 500 up and down the filter 300. For example, the ring 500 may include one or more formed on the outer surface of the chipping material 400 to maintain the ring substantially aligned with the axial position of the one or more openings 410 of the chipping material 400. The limit ribs 420 extending in the circumferential direction may cooperate with each other. The limiting rib 420 is configured to limit the longitudinal movement of the ring 500 to a predetermined distance, whereby the ring 500 moves the filter up and down relative to the position of the one or more openings 410 of the chipping material 400. The distance to be limited. Accordingly, the user can change the degree of longitudinal alignment between the openings 410 and 510 even when the ring 500 is in the open arrangement. Apart from this, the ring 500 and the limiting rib 420 cooperate to substantially prevent the ring 500 from sliding longitudinally along the filter, and to provide longitudinal alignment between the openings 410, 510. The degree can be kept constant.

  In the example shown in FIG. 7, the ring 500 includes one opening 510, and the chipping material 400 includes three openings 410 that are spaced apart in the circumferential direction of the filter 300. The three openings 410 of the chipping material 400 are radially aligned with the positions of the three grooves of the filter 300, respectively, so that external air flows into the grooves and passes through the additive material 350 as described above. ing. The three openings 410 of the chipping material 400 are located directly below the ring, i.e., the opening 510 of the ring 500 is axially aligned with the opening 410 of the chipping material 400 so that the opening 510 of the ring 500 is aligned. If not aligned with the opening 410 of the chipping material 400 corresponding to the groove, it prevents outside air from entering that particular groove. Each groove additive material 350 may include a different flavorant material 350. The ring 500 can be rotated to selectively align any one of the three openings 410 of the chipping material 400 with the opening 500 of the ring 500. As is apparent from the above description, the specific opening 410 of the chipping material 400 and the opening 510 of the ring 500 are aligned to be located radially inward from the specific opening 410 of the chipping material 400. External air is drawn into the groove. This is done by sucking at the mouth end of the filter 300. External air drawn into the groove is flavored by a flavoring agent 350 located in the groove before exiting through the mouth end of the groove or through the slit 341 and through the end face of the filter material 310. Of course, if external air is drawn into a groove through the corresponding opening 410 of the chipping material 400, chipping outside the filter 300 until it reaches the mouth end and / or the slit 341 of the filter 300. The non-porous nature of the material 400 and the non-porous nature of the liner 340 prevent external air from exiting the groove.

  Thus, the user of the filter 300 can remove the filter 500 from the mouth end of the filter at any time before or during smoking by rotating the ring 500 to align the opening 510 of the ring 500 with the groove containing the desired flavorant 350. The desired flavor of the resulting gas stream can be selected. For example, the flavor of the gas stream exiting the filter 300 can be switched from one flavorant material 350 to another while smoking by rotating the ring 500. Alternatively, the flavor of the gas flow can be switched from “flavored” to “no flavor” or vice versa by rotating the ring between open and closed configurations or between closed and open configurations. is there.

  Thus, a pack containing the same smoking article 100 allows the user to selectively smoke different cigarettes with different flavors.

  Next, an example of a method for manufacturing the filter 300 will be described. As known in the art, a plug of filter material is usually provided by supplying a substantially continuous stream of cellulose acetate tow to the funnel to provide a body of cylindrical cellulose acetate material. It is formed. The cellulose acetate material is passed through the garniture, and the plug paper supplied from the plug paper reel is attached to the filter material. The filter material wrapped with plug paper is then cut into individual segments for use in making the filter 300. The length to be cut is suitable for producing two cigarettes in series or into individual cigarettes as required. This cutting also involves first cutting the length of the filter material for use in multiple cigarettes and then cutting to a suitable length for use in making cigarettes in series or individually. It may be performed as a multistage process. The groove of the filter 300 is provided by placing a length of filter material 310 wound on the plug paper 320 between the first and second substantially parallel plates. The second plate is heated and provided with long groove-forming protrusions, and each protrusion corresponds to a groove of the filter. For example, the second plate includes three groove forming protrusions to form three grooves located at substantially equal intervals in the circumferential direction of the filter. The first plate moves in parallel on the second plate together with the filter material 310 engaged between the plates in order to roll the filter material on the protrusions described above. As a result, the groove forming projection is pushed into the cylindrical main body made of the filter material, and a groove is formed in the filter main body. During the groove forming process, the plug paper 320 is pushed inward into the groove to line both the groove and the cylindrical outer peripheral surface of the filter material 310. This is illustrated in FIG. In another method, the groove is formed in the filter material before the filter material 310 is wrapped in the plug paper 320. This is illustrated in FIG.

  After forming the grooves, a liner 340 made of a layer of lining sheet material is described above and inserted into each groove as shown in FIGS. This may be done before or after the filter material 310 is wrapped with plug paper as shown in FIGS. For example, as described above, the additive material 350 made of the flavor material 350 may be inserted into the groove before the filter 300 is wrapped in the chipping material 400. This is done using an injection device that includes a suitable injection nozzle configured to introduce additive material 350 from the additive reservoir into the groove.

  Alternatively, the filter 300 may include a generally cylindrical, hollow plastic cap or plastic shell that is coaxially connected to the smokable rod 200 using a suitable chipping material. As described above, a filter material such as cellulose acetate is provided inside the plastic cap, and the additive material is provided directly below the surface of the plastic shell. The shell may be provided with an opening so that external air is drawn through the additive material by suction at the end of the filter. This opening can be selectively opened and closed, for example, by rotating an external control device such as a ring as described above.
