Description

  The present invention relates to a filter for smoking articles.

  As used herein, a smoking article refers to a smokable article, such as a cigarette, cigar, or cigarillo, that includes tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes and non-flammable ( Heat-not-burn) material. The smoking article is provided with a filter for the smoker to inhale the gas flow.

  It is known that tobacco flavoring agents are used in smoking articles such as cigarettes to provide brand-specific flavors to smokers. For example, cigarette tobacco may be flavored with menthol or other approved standard flavoring agents to flavor the gas stream inhaled by the smoker.

  The present invention provides another method for flavoring a smoking article with a filter.

  According to the present invention, there is provided a filter for a smoking article comprising a plug made of a filter material and a packaging material mounted with an adhesive around the filter material, the adhesive containing a flavoring agent for the smoking article. provide.

  The flavoring agent may be naturally colored to provide a visually identifiable portion in the filter, thereby distinguishing it from other smoking articles by its unique appearance.

  The packaging material may include a sheet material in which an adhesive is applied in a predetermined pattern, and the sheet material is wound around the filter material.

  A plug made of a filter material may have a generally cylindrical outer periphery to which an adhesive is applied in a stripe shape.

  The end face of the plug made of filter material may have a normal circular shape, and the stripes of adhesive will be visually identifiable parts spaced along the circumference of the end face. May be configured. These visually identifiable portions may exhibit a castellated pattern along the periphery of the circular end surface.

  The adhesive material may include polyvinyl acetate and the naturally colored flavoring agent may include a brand-specific flavoring agent.

  The flavoring agent may be a flavoring agent for tobacco, and is not necessarily limited, but is an extract (eg, licorice, cocoa, hydrangea, oakashiwa (Japanese white bark magnesium leaf), camomil, koroha, clove, menthol, mint) , Anise fruit, Cinnamon, Herb, Winter green, Cherry, Berry, Peach, Apple, Drambuy, Bourbon, Scotch, Whiskey, Spearmint, Peppermint, Lavender, Cardamom, 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, Korea Mint oil from any of the genus, coffee and mint species), flavor masking agents, bitterness receptor site blockers, receptor site enhancers, sweeteners (eg sucralose, acesulfame potassium, aspartame, saccharin, May include at least one of cyclamate, lactose, sucrose, glucose, fructose, sorbitol or mannitol) and other additives such as aroma pyrazines, chlorophylls, minerals, plants or breath deodorants . These may be imitation, synthetic or natural ingredients and may be blends thereof. These may be in any suitable shape, for example oil, liquid or powder.

  Coloring additives such as charcoal may be added to the adhesive. Therefore, for example, when the filter material includes fibrous cellulose acetate, the adhesive portion of the filter can be visually identified by charcoal.

  The packaging material may include a plug wrap for the filter material.

  The invention also includes smoking articles such as cigarettes with filters. The cigarette includes a rod of smoking material, such as tobacco, attached to a filter by an adhesive comprising a tipping paper and a flavoring agent applied to the chipping paper.

  For a further understanding of the present invention, various aspects of the invention will be described with reference to the accompanying drawings.

1 is a schematic side view of a cigarette. FIG. FIG. 2 is an end view of the cigarette viewed from the direction of arrow A in FIG. 1. FIG. 3 is a partially exploded perspective view of the cigarette shown in FIGS. 1 and 2. It is a figure which shows the manufacturing process of the plug wrap for filters by this invention. It is a figure which shows the process of wrapping the surroundings of a filter material with a plug wrap in order to manufacture the filter by this invention.

  1, 2 and 3 show a smoking article in the form of a cigarette comprising a filter according to the invention. This cigarette includes a generally cylindrical tobacco rod 1 wound on paper, which rod is mounted coaxially to the filter 2 by a tipping paper 3 glued around one end and the cylindrical filter 2. Has been. 2 and 3 show a filter 2 comprising a substantially cylindrical tow made of a filter material 4 such as fibrous cellulose acetate. The filter material 4 is wound by a wrapping material 5 made of a plug wrap-shaped sheet material, and an adhesive 6 is applied to the plug wrap in a stripe shape, whereby the plug wrap 5 is wrapped around the filter material 4. By being wound, it is fixed at a predetermined position by the adhesive 6.

  A method for manufacturing the filter 2 having a predetermined length is shown in FIGS. As shown in FIG. 4, the flat sheet of the plug wrap 5 passes through the bonding station 7 in the direction of arrow B, and at this station, the nozzle 8 applies the adhesive 6 along the plug wrap in stripes in parallel and in the longitudinal direction. To do.

  As shown in FIG. 5, a generally cylindrical tow consisting of a plug wrap 5 and a filter material 4 is fed to the packaging station 9 in the direction of arrow C, where the plug wrap is wound around the filter material 4 and bonded nozzles. 10, whereby the plug wrap completely covers the filter material 4 to form a substantially cylindrical filter 11 having a predetermined length according to the present invention. The filter is then cut to a suitable length for an individual cigarette as schematically illustrated by dotted line 2 in FIG.

  As shown in FIG. 4, the adhesive stripe 6 is applied from the tank 13 through the nozzle 8. The adhesive may include conventionally used polyvinyl acetate, which may further include a flavoring agent for flavoring cigarette smoke. The flavoring agent may be naturally colored so that the adhesive 6 can be visually identified on the end face 13 of FIGS. 2 and 3. The adhesive portion 6 is arranged in a regular concavo-convex pattern around the circular end surface of the filter 2, so that the cigarette has a different appearance from other cigarettes. It is preferable that the number of stripes of the adhesive 6 applied to the plug wrap 5 is variously changed in order to provide different numbers of irregularities around the end face.

  The added flavoring agent may include substances or compounds approved for use in cigarettes, for example, menthol, Amakusa, caramel, or one of the flavoring agents listed above.

  During use, the smoke coming out of the burning tobacco rod 1 is sucked through the filter through the adhesive stripe 6, thereby providing the consumer with a flavored tobacco smoke.

  Of course, the adhesive stripe 6 may comprise a mixture of different flavors, for example a brand-specific flavor mixture so that the smoker can recognize the brand.

  In addition, the adhesive stripe 6 may contain a material approved for use in cigarettes, which acts as a colored material so that the stripe pattern is visible on the end face 13. Also good. For example, a white cellulose acetate filter rod with adhesive strips colored with Amakusa (black) may be used. Alternatively, filter rods formed substantially of carbon paper have a dark appearance, especially when used with carbon chipping paper. In that case, a strip of cream adhesive colored with vanilla may be applied to achieve the desired effect. If the adhesive stripe is lighter in color than the surrounding material, it is more preferable to use an adhesive material that does not mix with the surrounding material, such as a hot-melt adhesive.

  In another shape, a stripe of adhesive may be applied to the inside of the tipping paper 3 that adheres to the plug wrap 5 in order to give a flavor and also a characteristic pattern. If the product flavor is contained only in the adhesive stripe placed on the chipping paper, the flavor can be transferred from the adhesive to the surrounding material, such as menthol is preferred. . On the other hand, the flavor in use may be reliably delivered by improving ventilation, for example. The filter material 4 itself may also be colored. They may be colored with a naturally colored flavoring agent different from that used for the adhesive part 6 or an unscented colorant.

  Instead of the uneven shape shown in FIG. 2 and FIG. 3, some modification may be added to the pattern of the adhesive portion 6 in order to give a semicircular or other characteristic pattern, for example.

  The invention also includes further modifications or variations within the scope of the following claims.
