FIG. 3 shows a tape having a plurality of sealed pockets with thinned regions spaced along the length. FIG. 1 is a schematic view of a cigarette with a filter having a cut section of tape disposed inside the filter. Fig. 6 is a schematic diagram showing that the pockets are ruptured by strongly pushing the outside of the filter, where the thinned area guides the additive toward the end of the cigarette filter. Fig. 6 is a schematic showing that the pocket is ruptured by strongly pushing the outside of the filter, where the thinned area guides the additive towards the mouth end of the cigarette filter. 1 is a schematic diagram illustrating a method for manufacturing a tape having a plurality of sealed pockets having thinned regions spaced along the length. Fig. 6 is a schematic diagram illustrating another example of a section of tape inside a cigarette filter. Fig. 6 is a schematic diagram showing that a pocket is ruptured by strongly pressing the outside of the filter. 6 shows another example of an additive release member having a thinned region. Fig. 4 shows still another example of an additive release member having a thinned region, (a) is a perspective view, (b) is an end view, and (c) is an AA 'line shown in (b). (D) is a cross-sectional view taken along the line BB ′ shown in (b).

  FIG. 1 shows a tape 1, which has a plurality of additive-containing members in the form of sealed pockets 2 spaced along its length. Each pocket 2 has an inner space containing an additive. The tape and pocket may be formed from a flexible polymeric material such as polyvinyl alcohol (PVOH) or polyethylene (PE).

  As shown in FIG. 2, the cut section 1 a of the tape 1 may be positioned in the cellulose acetate plug of the filter 3 of the cigarette 4. By applying pressure on the outside of the filter 3, the smoker can break the pocket 2, thereby releasing the additive. In this way, the smoker can selectively flavor the smoke drawn from the cigarette 4.

  The tape 1 is provided with a thinned corner region 5 at one end of the pocket 2. As illustrated in FIG. 3, the pocket is broken at the thinned corner region 5 when pressure is applied to the outside of the filter 3. In the example of FIG. 3, the pocket 2 contains a smoke modifier (eg water, triacetin or a flavor), and the thinned corner area 5 guides the smoke modifier towards the tobacco rod of the cigarette 4. It is configured. This is particularly advantageous in filters where smoke flows more slowly near the end of the cigarette than near the end of the mouth, for example when a ventilation hole is provided near the end of the mouth. In this case, it is possible to lengthen the time during which the smoke modifier and the smoke interact by guiding the smoke modifier toward the end of the mouthpiece.

  Alternatively, as shown in FIG. 4, each pocket 2 may be provided with a thinned corner region 5 in the mouth end region of the pocket instead of the tobacco end region. In the example of FIG. 4, the smoke modifier in the form of a flavor is contained in the pocket 2. Accordingly, the pocket 2 of FIG. 4 is configured to guide the flavor toward the mouth end of the cigarette 4. As a result, the flavoring agent is released near the mouth end to maximize the flavor.

  A horizontal or vertical bag-filling method may be used for manufacturing the tape 1. The tape 1 may be formed from two or more polymer layers, which are sealed together and the unsealed areas form the pockets 2. Heat sealing, ultrasonic sealing, water bonding or any other suitable method may be used to form the seal.

  The thinned corner region 5 of the tape 1 may be formed by a modified vertical bag making and filling method. In particular, the sealing process is changed to provide a pocket 2 having a transverse edge that makes an acute angle with the longitudinal axis of the filter 3, thereby providing a thinned corner region 5.

  FIG. 5 shows a method for manufacturing the tape 1.

  In step A, a cavity 7 is formed in the first layer 6. This forming step includes a step of forming the first layer 6 in the shape of a mold (not shown) under vacuum. The cavity 7 protrudes from one side (for example, the lower side) of the layer 6. The cavity 7 is formed to have a transverse edge that forms an acute angle with the longitudinal axis of the first layer 6. In step B, the cavity 7 is filled with the additive 8. In step C, the second layer 9 is disposed on the first layer 6 on the side opposite to the side from which the cavity 7 protrudes (for example, the upper side). In step D, the layers 6, 9 are sealed together, for example using heat sealing. A sealed region 10 is formed around each cavity 7, thus forming a pocket 2 in the tape 1.

  The tape 1 may be manufactured by another method.

  For example, a cavity having a transverse edge that is normal to the longitudinal axis of the first layer may be formed. In this case, a transverse edge that makes an acute angle with the longitudinal axis of the tape may be provided at the portion of the sealed area between the pockets.

  Other examples of tapes having a thinned sealing area may be manufactured in a similar manner.

  For example, an unsealed region may be provided between the pockets so that the sealed region at the lateral edge of each pocket is narrower than the sealed region at the longitudinal edge of each pocket. When pressure is applied to the pocket, the tape layer separates in this narrow sealed area and the pocket is torn.

  Alternatively, the sealed area of the longitudinal edge of each pocket may be made narrow enough so that the tape layer separates in this area.

  In any case, the sealed region may be weakened by including one or more unsealed regions therein. For example, a sealed region may include a narrow unsealed region ("line") that passes through it in a direction perpendicular to the edge of the pocket. This line is narrow enough so that the additive cannot pass through it, but the layers of the tape are easily separated. The strength of the sealing portion can be adjusted by changing the temperature of the sealing unit, for example.

  The tape 1 may be wound around a reel, drawn from the reel into a flow of filter tow passing through a filter rod manufacturing machine, and incorporated into a long filter rod. The cutter of the filter maker then cuts the long filter rods into segments, forming individual filter rods each containing one or more pockets 2. This filter manufacturing process is substantially similar to the process described in the following Patent Document 1, but a long tube containing a capsule of the following Patent Document 1 is replaced with the tape 1. The following Patent Document 1 is cited as a reference in the present specification.

  Therefore, the pocket 2 and its thinned region 5 can be easily arranged in the filter 3 by the above-described method of the present invention.

  In some examples, a portion of the tape 1 may be folded back along the longitudinal edge of the tape 1 and fastened to the tape 1. This can obtain the effect of reducing the tensile stretching in the longitudinal direction of the tape 1 and increasing the tensile strength in the longitudinal direction. This makes it easier to handle the tape 1 especially during manufacture, for example when the tape 1 is wound on a reel and then pulled out.

  FIG. 6 a shows another example of a section 11 a of tape 11 located in the cellulose acetate plug of filter 13 of cigarette 14. Section 11a includes a first fluid containing pocket 12a and a second fluid containing pocket 12b. The pair of pockets 12 a and 12 b are at the same position in the longitudinal direction along the tape 11.

  As shown in FIG. 6b, the pockets 12a, 12b are arranged such that both the pockets 12a, 12b break simultaneously and both fluid additives are released simultaneously by crushing with a finger to apply pressure to the outside of the filter. ing. A thinned area (not shown) in each pocket may guide the smoke modifier toward the cigarette rod and / or mouth end, in which case the direction is added as described above. You may decide according to the kind of agent.

  The tape 11 may be manufactured by the same method as described above and contained in the filter 13.

  FIG. 7 shows an example of the additive release member 15. The additive release member 15 is a substantially elongated tube, and preferably has a substantially annular or elliptical cross section.

  The additive release member 15 is substantially tubular and may have a curved end. The flange 16 may extend at the curved end, which is excess material when the outer shell is formed.

  The additive release member 15 includes a thinned line 17. The thinned line extends in the longitudinal direction, preferably substantially the entire length of the additive release member 15. The additive release member 15 tears only along the thinned line, or first tears along the thinned line, and then immediately tears over substantially the entire area of the additive release member 15. The thinned line may be formed by a joint between two parts of the additive release member 15.

  The additive release member 15 may be manufactured using a blow fill sealing method or a bagging sealing method.

  FIG. 8 shows still another example of the additive release member 20. The additive release member 20 includes a body 21 and an additive 22. Additive 22 may comprise a fluid, powder or any other suitable additive material. The body 21 is made of a flexible material, preferably a polymer material such as polyvinyl alcohol (PVOH). The fuselage 21 includes a tubular section 21a having a first end section 21b at one end and a second end section 21c at the other end. Sections 21a, 21b and 21c together form a container for additive 22.

  The first end section 21b includes an end wall that closes one end of the tubular section 21a. This end wall is preferably rounded. Tubular section 21a is substantially cylindrical toward first end section 21b, and first end section 21b may include a substantially hemispherical end wall as shown.

  The wall of the tubular section 21a has been modified to form a seal at the second end section 21c. Preferably, the wall sections corresponding to the two opposite halves of the tubular section 21a are flat and in contact, in which case the contact area is a substantially flat rectangular area. The two wall sections may be joined together in any suitable manner as described below.

  The additive release member 20 can be produced by the method described below. The unsealed fuselage, ie the fuselage 21 that does not have the second end section 21c, is initially molded in any suitable manner. The unsealed body is then filled with additive 22. This involves holding the unsealed body vertically with its open end facing upwards. The unsealed fuselage is then sealed by deforming the wall sections of the tubular section 21a and joining them together, thereby forming the second end section 21c. The wall sections may be joined together by heat sealing, ultrasonic welding, water bonding or any other suitable method.

  In use, the additive release member 20 includes an additive 22 until released by a smoker. Depending on the pressure applied to the member 20, the member 20 is torn at the second end section 21c, for example, by a smoker crushing the outside of the filter in which it is contained. In particular, the seal between the wall sections is designed to break partially or completely. The additive 22 is then forced out of the member 20 via the torn second end section 21c. The member 20 can be aligned with the longitudinal axis of the filter and thinned at either end so that the additive 22 is released towards either the tobacco end or the mouth end of the filter. Can have different areas.

  The additive release members 16 and 20 may be connected by a long member, for example, as described in Patent Document 1 below, or may be attached to the tape with an adhesive. The filter may be manufactured by a method similar to that described above. Alternatively, the additive release members 16 and 20 may be directly introduced into the filter.

  Many further modifications, variations and implementations are possible.

  For example, the additive-containing member may have any suitable shape.

  Furthermore, while the insertion of the additive-containing member into the filter rod has been described above, in other examples the additive-containing member may be located elsewhere in the smoking article, for example around the smoking article or inside the tobacco rod. In some examples, tapes 1, 11 may be configured as a plug wrapper or chipping paper for use in the manufacture of cut strips or smoking articles.

  In addition, additive-containing members in the form of additive-containing pockets have been described above, but in some cases, alternatively or additionally, the additive-containing member has, for example, flavor pellets or beads or one or more additive components. Other solid materials may be included.

  In addition, the additive-containing pocket described above releases the additive under pressure, but other release mechanisms are also available. For example, a member containing a specific additive may release the additive by dissolving in accordance with the presence of moisture. When smoke is thus sucked from the final smoking article, moisture in the smoke field may cause the additive to be released.

  The terms additive release member and additive-containing member are used interchangeably herein.

  The additive release member may be a capsule having an outer shell containing an additive fluid (liquid or powder) in an internal cavity. The outer shell of each additive release member is fragile so as to release all the additive upon application of pressure.

  The filter may include a reaction surface that can press the additive release member to facilitate the release of the additive. In particular, the additive release member may be disposed on the outer surface of the filter. A radially adjacent filter medium may provide a reaction surface that can press the additive release member. Preferably, the filter media may be relatively hard to form a reaction surface (eg, by being rich in plasticizer) and may have a hardness that is greater than 90% of the Filtrona scale. The additive release member may be disposed within the filter media or may be disposed in a cavity adjacent to the filter media. The cavity may be formed by an elongate inner rod of filter media, which is surrounded by one or two filter media annular outer sections. The cover layer that forms the outer surface of the filter is attached to one or both of the outer sections of filter media and is spaced from the inner rod that forms the cavity. The inner rod is preferably stiffer than the annular outer section by optionally containing more plasticizer.

  Alternatively, each additive release member may be actuated to release a plurality of individual amounts of additive content, preferably by a plurality of individual pressurizations. This type of additive release member may include an outer shell that is elastically or plastically deformable and is preferably configured to release the additive through a slit formed in a predetermined area. . Alternatively, this type of additive releasing member may include a porous absorbent base material (for example, an open cell foam) having an open cell structure containing the additive. The substrate may be at least partially elastically deformable. The substrate is surrounded by an outer shell to hold the additive and may be fragile, elastically deformable, plastically deformable or a thin coating. This substrate may form a separate additive release member or may be in the form of an annulus provided in the first filter section. Alternatively, this type of additive release member includes a porous matrix having a closed cell structure (e.g., closed cell foam) that contains the additive in individual cavities and is plastically deformable to release the additive. May be included.

  These additive release members may be individually attached to the filter or substrate. Alternatively, these additive release members may be connected by a web or may be connected by a laminated strip of sheet material. Alternatively, the strip of sheet material may be formed such that the additive release member does not have a separate outer shell and the strip of sheet material contains the additive.

  The additive release member may be manually operated to release the additive, or the additive may be removed from the at least one additive release member by moving the movable part around the smoking article. It may be configured to release. This movement is preferably slid or rotated on the outer surface of the filter by a ring or C-shaped clip. The filter may provide a reaction surface against which the additive release member is pressed by the movable part.

  The additive release member may be located in one or more grooves that extend circumferentially, longitudinally, or spirally. Alternatively, the movable part may include a cover layer that forms two adjacent surfaces, and the additive release member is located between the adjacent surfaces, thereby allowing movement of the adjacent surfaces of the cover layer. The additive is released from at least one additive release member.

  The additive release member is preferably a sphere. Alternatively, the additive release member may be a long one extending parallel to the longitudinal axis of the filter. This elongated additive release member preferably has an annular or elliptical cross-section and contains more additive than an additive release member of the same diameter. This elongate additive release member preferably has a maximum width of less than 3.5 mm or less than 3 mm, or 2 mm to 3 mm. Alternatively or additionally, the elongated additive release member has a radial cross-sectional area of less than 50% and optionally less than 40% or 30% of the radial cross-sectional area of the smoking article.

  These additive release members are preferably located individually in the smoking article. Alternatively, the plurality of additive release members may be surrounded by an outer wall or an outer capsule. The outer capsule may be porous or may be configured to break or deform to release the additive upon compression. The outer capsule may further encapsulate itself. The additive may be included in a plurality of individual cavities in the open cell substrate or the closed cell substrate. Open cell substrates and optional closed cell substrates have outer capsules. One or more additive release members may be attached to the outer surface of the substantially larger additive release member. Alternatively, a plurality of additive release members of the same or different sizes may be attached together. Any of these embodiments may be considered as multiple members associated with a single structure.

  Embodiments of the present invention are configured to comply with applicable laws and / or regulations, such as those relating to flavors, additives, emissions, ingredients, etc. according to non-limiting examples. For example, the present invention is configured such that a smoking article embodying the present invention complies with regulations that may be applied before and after the smoker adjusts, and also after the release of one or more additional additives. .
