Traditional hand-rolled tobacco products are made by consumers using loose cut tobacco and wrapping paper. Consumers usually weigh the cut tobacco and spread it evenly along the length of the wrapping paper to form a groove in the wrapping paper so that the cut tobacco is contained at the bottom of the groove. Made to handle shredded tobacco by rolling a piece of paper between your thumb and other fingers to form a cylindrical tobacco rod, and wrap the paper around the shredded tobacco to form a smokable cigarette. Adhere the free edge of the wrapping paper to the outer surface of the cylindrical article. This method of forming cigarettes requires that the cut tobacco and the wrapping paper be handled separately, resulting in variability in the amount of cut tobacco in the cigarette. This results in an inconsistent consumer smoking sensation. In addition, there is a risk that the cut tobacco will spill and disappear if the cut tobacco and the wrapping paper are handled separately.

Hand-rolled tobacco products have also been proposed with a wrapping paper having a layer of cut tobacco adhered to one side thereof. However, these pre-cigarette-wrapped papers do not always provide the consumer with a consistent smoking sensation. For example, pre-filled wrapping paper is more or less tight to roll and fold. Therefore, the suction resistance may vary depending on the smoking article.

The laminate of the present invention comprises a layer of tobacco material and a support sheet. This layer of tobacco material has a roughened surface to provide a permeable structure that allows air to be drawn in when the stack is rolled or folded into a smoking article. When the laminate is rolled or folded, at least some of the surface of the layer of tobacco material contacts the support sheet. The presence of the roughened surface provides a channel through which air is drawn through the tobacco material or between the tobacco material and the adjacent support sheet.

The term "tobacco material" as used herein includes all smoking materials, including but not limited to, for example, leaves, parts of leaves, flowers, roots, and other tobacco species. All parts and mixtures thereof, reconstituted tobacco, alternative tobacco, tobacco derivatives, dried fruits or herbs. In one embodiment, the tobacco material comprises reconstituted tobacco.

The layer of tobacco material has a rough surface. For example, the layer of tobacco material may have a non-uniform or irregular surface. The roughened surface may be formed as the layer of tobacco material is made. For example, the roughened surface may be provided by compressing a layer of tobacco material longitudinally or laterally. For example, an irregular surface may be formed by placing a strand of tobacco material on a paper wrapper and compressing it.

In some embodiments, the roughened surface may be produced by the presence of fibrous material. For example, large particles of fibers are evenly or randomly distributed across the surface of the layer of tobacco material, providing a roughened surface with a series of grooves or channels for the passage of air within the tobacco material. These pathways may be in the layer of tobacco material or may be formed between the surface of the layer of tobacco material and the surface of the adjacent layer when rolled or folded. Alternatively, there may be relatively larger particles of fibers in the layer of tobacco material. Due to their larger size, the tobacco materials are formed to have a rough surface rather than a smooth surface. The fibrous material may be tobacco, reconstituted tobacco (such as that referred to as Fibex), wood or paper, cellulosic sources such as waste lamina, non-combustible inorganic fillers, binders and Other sheet materials such as smokable fillers that include a blend of aerosol generating means may be used.

In one embodiment, when the tobacco material is rolled or laminated to form a laminate, no layer of tobacco material is crushed or broken apart or separated from the support sheet. The tobacco material may be flexible. For example, additives may be included that allow the layer of tobacco material to be handled on the support sheet without tearing. In particular, various gums and pectins may be used as binders to maintain their integrity when making layers of tobacco material. More preferred as a binder is natural pectin, for example fruit, citrus, tobacco pectin, guar gum such as hydroxyethyl guar and hydroxypropyl guar, locust bean gum such as hydroxyethyl and hydroxypropyl locust bean gum, Examples include alginate, starch such as processed starch and derivatized starch, cellulose such as methyl cellulose, ethyl cellulose, ethyl hydroxymethyl cellulose and carboxymethyl cellulose, tamarind gum, dextran, pralone, konjac flour and xanthan gum.

In some embodiments, the tobacco material may further comprise water. When the reconstituted tobacco contains water as an additive, the tobacco material becomes softer. For example, the tobacco material may contain from about 5% to about 20% by weight water. More preferably, the tobacco material may contain from about 12% to about 16% by weight water.

In another embodiment, the layer of tobacco material may further comprise additives such as flavors and/or flavoring agents. As used herein, the terms "flavor" and "flavorant" refer to materials that, where permitted by law, can be used to create a desired taste or aroma in an adult consumer product. These are extracts (e.g. licorice, hydrangea, jojoba, chamomile, fenugreek, clove, menthol, cacao, peppermint, anise fruit, cinnamon, medicinal herbs, medaka, cherry, berries, peach, apple, drambui, bourbon, scotch, whiskey. , Spearmint, peppermint, lavender, cardamom, celery, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey extract, rose oil, vanilla, lemon oil, orange oil, cassia, oleander, cognac, jasmine, ylang ylang, medicinal salvia, wikia , Allspice, ginger, anise, coriander, coffee, or peppermint oil from any species of mint), flavor enhancers, bitter taste receptor site blockers, sensory receptor site activators or stimulants, sugars and/or Or sugar substitutes (eg sucralose, acesulfame potassium, aspartame, saccharin, cyclamate, lactose, sucrose, glucose, fructose, sorbitol or mannitol), and charcoal, chlorophyll, minerals, botanicals, or halitosis deodorants, etc. Other additives may be included. These may be imitation, synthetic or natural ingredients, or mixtures thereof. These may be in any suitable form such as oil, liquid or powder.

In some embodiments, the layer of tobacco material may include humectants such as glycerin, polyethylene glycol and propylene glycol.

In some embodiments, the roughened surface may extend across the entire thickness of the layer of tobacco material. If the rough surface extends across the entire thickness of the layer of tobacco material, the rough surface will provide a minimum resistance no matter how tightly rolled or folded the laminate. In some embodiments, the rolled laminate provides a low drag resistance that is consumer preferred.

In one embodiment, the pressure drop of the rolled laminate is from about 30 mm WG (Water Gauge) to about 200 mm WG. Preferably, the pressure drop is about 95 mmWG to about 155 mmWG. In some embodiments, the pressure drop is 0.2 to 1.5 mmWG per mm of rolled laminate length, more preferably 0.5 to 1.0 mmWG per mm.

In one embodiment, the layer of tobacco material has a thickness of about 0.5-3 mm.

In addition to a layer of tobacco material, the laminate may include a support sheet. The term "sheet" as used herein refers to any material suitable for supporting a cigarette and capable of being wrapped around a cigarette. The support sheet may be made of any sheet suitable for surrounding a tobacco rod of a smoking article. In some embodiments, the support sheet may include paper. Examples include, but are not limited to, conventional wrapping paper used for hand-rolled or common preformed cigarettes. The material may have the texture of paper, or may have a rough, moist feel or otherwise differ from the texture of normal paper. For example, the support sheet may be a sheet containing recycled material such as recycled tobacco, or a sheet containing chalk, or a sheet containing a blend of inorganic filler material, binder and aerosol generating means.

In some embodiments, the layer of tobacco material covers the entire support sheet except for at least one piece free of tobacco material. More preferably, the tobacco-free strip is located near or along the edge. In some embodiments, adhesive may be applied to at least one of these tobacco-free edges. In some embodiments, the laminate is rolled to form a smoking article. As the laminate is rolled, areas free of tobacco material along the edges of the support sheet may be adhered to the outer surface of the smoking article to hold the laminate in a substantially cylindrical shape.

In some embodiments, the layer of tobacco material may cover the entire support sheet except for the strip located along the longitudinal edge. When the strips of tobacco material are placed along the longitudinal edges, the laminate is easier to roll when formed into a smoking article.

In one embodiment, a pack comprising at least one laminate according to the present disclosure is provided. For example, the pack may include many stacks that may be rolled or folded to form a smoking article. In some embodiments, the laminate may be provided individually wrapped in a wrapper. If the laminate is held in a separate wrapper, the humidity within the wrapper may be optimized. For example, the humidity within the wrapper can be from about 5 wt% water to about 20 wt% water, and more preferably from about 12 wt% water to about 16 wt% water. The internal air of the individual wrappers may be selected to ensure that the layer of tobacco material is kept fresh and the desired moisture content is maintained, which allows the laminate to retain its structural integrity. It can be rolled or folded. In order to keep the optimum moisture content of the laminate constant, the laminate is provided in a freshness-wrapped package, which allows it to retain the same odor and texture as conventional cigarettes.

In some embodiments, the laminate may further include a removable layer overlying the support sheet. For example, the laminate may have removable cutouts that expose the adhesive when removed from the support sheet. In some embodiments, the removable protective sheet may prevent loss of tobacco material from the layer of tobacco material during shipping and storage. In addition, the protective sheet may prevent deterioration of the layers of tobacco material to ensure that the consumer can roll or fold the laminate as desired.

In some embodiments, the laminate may include a layer of tobacco material arranged such that the laminate is capable of receiving a filter plug when the laminate is rolled or folded. For example, the layer of tobacco material may not extend to the edge of the support sheet. In particular, one edge of the laminate sheet may be shaped to form a cavity for receiving a filter plug when the laminate is rolled or folded. In this case, the consumer may place the filter plug in this tobacco-free area when the stack is rolled or folded. Providing the consumer with a smoking article by rolling or folding the laminate around the filter plug.

In another embodiment, the rolled laminate may be smoked without a filter plug.

In another embodiment, the laminate may be used in a "hand-rolled" type tobacco industry product, Cigarillo, Glo or any other suitable tobacco industry product.

The laminated body 10 is shown in FIG. The laminate 10 includes a support sheet 12 and a layer 14 of tobacco material.

When rolled up as shown in FIG. 2, the laminate 10 forms a smoking article 20.

FIG. 3 shows a laminate 10 that includes a support sheet 12, a layer of tobacco material 14, and a tobacco-free region 16 of the support sheet 12. Such a laminate allows the filter plug to be placed in the tobacco-free region 16 when making a smoking article. When rolled, this tobacco-free region 16 will form a hollow tube for receiving a filter plug.
