details

Typical rolled tobacco products are made by the user through the use of loose cut tobacco and rolling paper. The consumer typically removes the cut tobacco and spreads it evenly along the length of the paper, forms a channel with paper so that the cigarette is included at the bottom of the channel, and rolls the paper between the fingers and the thumb to manipulate the cigarette to form a substantially cylindrical A phosphorous tobacco rod is formed, the paper is rolled around the cigarette, and the free edge of the paper is struck on the outer surface of the cylindrical article being manufactured to form a smokeable cigarette. Methods of forming such cigarettes require handling the cigarette and paper separately, resulting in cigarettes having varying amounts of tobacco. This gives the consumer an inconsistent smoking experience. There is also a risk of losing cigarettes by spilling them separately from cigarettes and paper.

Also, a rolling tobacco product has been proposed in which the paper is provided with a layer of tobacco attached to one side of the paper. However, these prefilled papers do not always provide a consistent smoking experience for the user. For example, the prefilled paper may be folded or curled somewhat firmly. Thus, the suction resistance can vary from smoking article to smoking article.

The laminate according to the invention comprises a layer of tobacco material and a support sheet. The layer of tobacco material includes a rough surface to provide a permeable structure through which air can be drawn out when the laminate is rolled up or folded into a smoking article. At least a portion of the tobacco material layer surface contacts the support sheet when the laminate is curled or folded. The presence of the rough surface provides a channel through which air can be drawn through or between the tobacco material and the adjacent support sheet.

As used herein, “tobacco material” refers to any smokeable material and leaves, leaf parts, flowers, roots and stems, and blends thereof of any part, such as any member of the genus Nicotiana . (blend), reconstituted tobacco, tobacco substitutes, tobacco derivatives, dried fruits or herbs, and the like. In some embodiments, the tobacco material comprises reconstituted tobacco.

The tobacco material layer has a rough surface. For example, the tobacco material layer may be described as having an uneven or irregular surface. The rough surface may be formed when producing the tobacco material layer. For example, pressing the layer of tobacco material longitudinally or laterally can provide a rough surface. For example, strands of tobacco material may be placed on paper and compressed to form irregular surfaces.

In some embodiments, the rough surface can be produced by the presence of fibrous material. For example, larger particles or fibers may be uniformly or randomly distributed across the surface of the tobacco material layer to provide a rough surface comprising a series of channels or pathways within the tobacco material through which air may pass. These pathways may be in the tobacco material layer or may be formed between the surface of the tobacco layer and an adjacent layer when dried or folded. Alternatively, relatively large fiber particles may be present in the tobacco material layer. Their larger size prevents tobacco material from forming a smooth surface and thus creates a rough surface. Fibrous materials can be cellulose sources such as tobacco, reconstituted tobacco (including, for example, so-called Fibex), wood or paper, waste lamina, or other sheet materials, such as non-combustible inorganic fillers. It may be derived from smokeable filler materials including blends of binders, binders, and aerosol generating means. Most preferably, the fibrous material includes smokeable materials, such as cut tobacco stems.

In some embodiments, the tobacco material may be flexible to allow the laminate to be rolled up or folded without cracking, fragmentation or otherwise separating from the support sheet of the tobacco material layer. For example, the tobacco material layer may include additives that allow the tobacco material layer to be manipulated on the support sheet without breaking. In particular, various gums and pectins can be used as binders when preparing the tobacco material layer to help maintain the integrity of the tobacco material layer. Preferred binders are natural pectins, such as fruits, citrus fruits, tobacco pectin, guar gums such as hydroxyethyl guar and hydroxypropyl guar, locust bean gum such as hydroxyethyl and hydroxypropyl locust Empty gums, alginates, starches such as modified or derivatized starches, celluloses such as methyl, ethyl, ethylhydroxymethyl and carboxymethyl cellulose, tamarind gum, dextran, pullalon, konjac Powder, xanthan gum and the like.

In some embodiments, the tobacco material may further contain water. If the reconstituted tobacco material contains water as an additive, the tobacco material is more flexible. For example, the tobacco material may contain about 5 wt% water to about 20 wt% water. Preferably, the tobacco material contains about 12 wt% water to about 16 wt% water.

In other embodiments, the tobacco material layer may further comprise additional additives such as flavorings and / or flavoring agents. As used herein, the terms "flavor" and "flavour" refer to materials that, if allowed by local regulations, can be used to produce the desired taste or flavor in products for adult consumers. These extracts (e.g. licorice, hydrangea, Japanese white magnolia leaf, chamomile, fenugreek, cloves, menthol, cacao, Japanese peppermint, anise seed, cinnamon, herb, zelkova, cherry, berry, peach, apple, Drambuie, Bourbon, Scotch, Whiskey, Spearmint, Peppermint, Lavender, Cardamom, Celery, Cascarilla, Nutmeg, Sandalwood, Bergamot, Geranium, Honey Essence, Rose Oil, Vanilla, Lemon Oil, Orange Oil , Cassia, caraway, cognac, jasmine, ylang-ylang, sage, fennel, piment, ginger, anise, cilantro, coffee or mint oil of any species of Mentha) , Flavor enhancers, bitterness receptor site blockers, sensory receptor site activators or stimulants, sugars and / or sugar substitutes (e.g. sucralose, acesulfame potassium, aspartame, saccharin, cyclate, lactose , Sucrose, article Course, fructose, sorbitol or mannitol) and other additives, for example, may include charcoal, chlorophyll, minerals, plant material or breath refreshing agent (breath freshening agent). These may be mimic, synthetic or natural ingredients or blends thereof. These may be in any suitable form, for example oils, liquids or powders.

In some embodiments, the tobacco material layer can include humectants such as glycerol, polyethylene glycol, and propylene glycol.

In some embodiments, the rough surface may extend over the entire thickness of the tobacco material layer. If the rough surface extends over the entire thickness of the tobacco material layer, the rough surface provides minimal resistance regardless of how tightly the laminate is dried or folded. In some embodiments, the dried laminate provides low suction resistance for consumer preference.

In some embodiments, the pressure drop of the dried laminate is between about 30 mm WG (Water Gauge) and about 200 mm WG. Preferably, the pressure drop is about 95 mm WG to about 155 mm WG. In some embodiments, the pressure drop is between 0.2 and 1.5 mm WG, preferably between 0.5 and 1.0 mm WG / mm, per mm length of dried laminate.

In some embodiments, the thickness of the tobacco material layer is about 0.5 mm to about 3 mm.

In addition to the layer of tobacco material, the laminate includes a support sheet. As used herein, "sheet" is intended to refer to any material that is suitable for supporting a cigarette and that can be wrapped by itself. The support sheet can be made of any sheet suitable for enclosing the tobacco rod of the smoking article. In some embodiments, the support sheet may comprise paper. Examples include, but are not limited to, standard wrapping paper used for rolled or pre-made cigarettes and reconstituted tobacco sheets. This material may have a paper texture, may be rough, moist or otherwise distinguished from standard paper textures. For example, the support sheet can be a sheet comprising any reconstituted material comprising reconstituted tobacco material, or a sheet comprising choke, or a sheet comprising a blend of inorganic filler material, binder and aerosol-generating means. .

In some embodiments, the tobacco material layer covers the entire area of the support sheet except for at least one strip without tobacco. Preferably, the tobacco free strip is located near or along the edge. In some embodiments, an adhesive may be applied to at least one of these tobacco free edges. In some embodiments, the laminate is curled to form a smoking article. When the laminate is curled, a tobacco free area along the edge of the support sheet may be attached to the outer surface of the smoking article to maintain the laminate in a substantially cylindrical shape.

In some embodiments, the tobacco material layer may cover the entire area of the support sheet except for strips located along the longitudinal edges. When the tobacco free strip is positioned along the longitudinal edge, the laminate can be more easily rolled up into smoking articles.

In some embodiments, a pack containing at least one laminate according to the present invention is provided. For example, the pack may contain a number of laminates that can be rolled up or folded into smoking articles. In some embodiments, the laminate may be provided in a individually sealed wrapper. When the laminate is held in a separate wrapper, the moisture in the wrapper can be optimized. For example, the moisture in the wrapper may be about 5 wt% water to about 20 wt% water, preferably about 12 wt% water to about 16 wt% water. The inner atmosphere of the individual wrapper may be selected to ensure that the tobacco material layer is kept fresh and to maintain the desired moisture content so that the laminate can be rolled up or folded while maintaining structural integrity. In order to maintain the optimized moisture content of the laminate, the laminate can be provided with a modified atmospheric wrapper to maintain aroma and texture similar to conventional dried cigarettes.

In some embodiments, the laminate can include additional removable layers located on the support sheet. For example, the laminate may have a removable separator that exposes the adhesive when removed from the support sheet. In some embodiments, the removable protective sheet can prevent the loss of tobacco material from the tobacco material layer during transportation and storage. In addition, the protective sheet can help prevent degradation of the tobacco material layer to ensure that the laminate can be dried or folded as desired by the user.

In some embodiments, the laminate may include a layer of tobacco material positioned to receive the filter plug when the laminate is rolled or folded. For example, the tobacco material layer may not extend to the edge of the support sheet. In particular, one edge of the laminate sheet can be shaped to form a cavity to receive the filter plug when the laminate is rolled up or folded. In this case, when the laminate is curled or folded, the user can position the filter plug in this tobacco free area. A smoking article is provided to the user by rolling or folding the laminate around the filter plug.

In another embodiment, the dried laminate can be smoked in the absence of a filter plug.

In another embodiment, the laminates may be used in "make your own cigarette" type tobacco industry products, cigarillo, Glo or any other suitable tobacco industry product.
