Definitions

  • the invention relates to a pouch made of a nonwoven material containing a tobacco material and/or another nicotine-containing material, hereinafter also referred to as a snus pouch, oral pouch or oral tobacco pack, these terms applying both to tobacco material and to pouches containing other nicotine-containing material.
  • Oral tobacco or smokeless tobacco is a tobacco product or nicotine-containing tobacco substitute (hereinafter also: nicotine-containing substitute, nicotine-containing substrate, other nicotine-containing material or tobacco substitute) that enables rapid absorption of nicotine through the oral mucosa. Tobacco smoke is not released.
  • Oral tobacco packs are known which contain a generally moist tobacco composition in a pouch made of a nonwoven material.
  • comparable products are also known which contain a dry, often not brownish but white nicotine-containing substitute instead of moist tobacco.
  • Snus is a form of oral tobacco that is particularly common in Scandinavia and is made from dried, ground tobacco with water, salt and flavorings. Snus is usually packaged in small cellulose bags and consumed as portion snus. With white portion snus, the pouch is dry to improve storage properties. In some cases, white portion snus uses a nicotine-containing substitute instead of tobacco. With original portion snus, the bag is moist. The snus pouch is placed behind the upper lip or lower lip. It releases tobacco flavor and nicotine within 15 to 60 minutes. The bag is then removed from the mouth.
  • Nonwovens made from viscose fibers that are chemically bonded ( chembound ) with binding agents basically meet these different requirements and are established on the market as a standard material for oral tobacco packs.
  • the use of a suitable binder allows thermal sealing of the non-thermoplastic nonwovens made of viscose fibers, which are advantageous because of their spontaneous wettability with saliva and their softness. It is important that the binding agent is chosen so that no sharp edges are created when sealing the bag.
  • the EP 3 223 636 B1 describes the use of a chemically bonded nonwoven made of viscose fibers with a certain proportion of viscose fibers with a multilobal (trilobal) cross section to optimize the feel, especially for oral use, and for rapid wetting.
  • the proportion of multilobal fibers increases the optical transparency of the fleece, accelerates wetting through increased capillary action of the channels formed by the multilobal fibers and offers a pleasant surface roughness upon oral contact.
  • the multilobal fibers are relatively expensive.
  • Such cellulosic fibers with a multilobal cross section are manufactured by the Kelheim Fibers company and sold under the name Galaxy Fiber.
  • the US 9,913,491 B2 describes the use of a nonwoven fabric to make a snus bag.
  • a perforated, hydroentangled nonwoven made of viscose fibers is preferably additionally treated with a chemical binder in order to obtain the desired material properties.
  • the perforation increases the permeability of the nonwoven for saliva and flavors and reduces its bending stiffness.
  • the WO 2016/040754 A1 discloses a method of making a bag from an embossed nonwoven fabric containing a tobacco material.
  • the nonwoven fabric includes fibers based on cellulose and binding fibers.
  • the higher number of different substrates makes it desirable to label the products with regard to their respective properties and to present the diversified product portfolio in an attractive manner for the customer. This would be desirable directly on the product, in addition to the conventional advertising options on packaging containing the product.
  • the invention is based on the object of providing an oral tobacco pack that enables the properties of the nonwoven material to be adjusted more easily to the respective substrate.
  • a method for producing the bag from a nonwoven material containing a tobacco material and/or another nicotine-containing material is to be provided.
  • the task is solved by a bag according to claim 1. Furthermore, the task is solved by a method according to claim 10. Advantageous embodiments of the bag and the method are specified in the subclaims and in the following description.
  • the bag according to the invention made of a nonwoven fabric contains a tobacco material and / or another nicotine-containing material, the nonwoven fabric being a chemically consolidated or a mechanically consolidated nonwoven fabric, fibers based on cellulose, a binder on the surface of the fibers, compacted zones and not or comprises compacted zones to a lesser extent and the at least partially crosslinked binder holds the compacted zones in the compacted state.
  • Nonwovens suitable for snus bags e.g. made from chemically bonded fibers containing viscose
  • non-woven fabrics with maximum permeability for flavors are used for snus bags. Such a material has a relatively open pore structure.
  • the nonwoven material By locally pressing (embossing) the material, the nonwoven material can be compacted in one or more defined zones in a simple calendering process with an engraving roller (embossing roller) and a smooth roller, and thus the pore structure in the area of the one or more compacted zones can be more or less closed and, if necessary .occlude to a lesser extent in the less compacted zones than in the compacted zones.
  • the nonwoven fabric In the zones compacted to a lesser extent, the nonwoven fabric is compacted to a lesser extent than in the compacted zones.
  • the nonwoven is a textile fabric and the compacted zones are formed by compacting the nonwoven in a direction perpendicular to the two main directions of expansion of the nonwoven.
  • the binder connects the fibers of the nonwoven fabric in the compacted zones and, if necessary, in the zones compacted to a lesser extent by gluing, mechanical entanglement or other interactions, whereby these zones are held or fixed in the respective compacted state.
  • the fibers can be glued together by at least partially crosslinking the binder when the nonwoven is pressed together due to an increase in pressure and temperature in the compacted zones.
  • the crosslinking can be brought about by an increase in the temperature of the rollers due to the heat released during pressing by the rollers and/or by targeted heat supply.
  • the fibers can also be glued together by heating and cooling thermoplastic binders or by compressing pressure-sensitive binders.
  • the nonwoven material is permanently compacted and kept closed in the compacted zones.
  • the compacted and closed zones remain largely compacted and closed even when wet during oral use.
  • they point compacted zones have a reduced permeability (passage of saliva with flavorings of the tobacco material) compared to the non-compacted or to a lesser extent compacted zones of the nonwoven material.
  • the permeability of the nonwoven material in the compacted zones can be negligibly low.
  • the permeability is not or only partially reduced by compaction of the fibers, so that the nonwoven fabric can retain its original or only partially reduced permeability there.
  • the overall permeability of the nonwoven material to the starting material used can be reduced and adapted to the respective tobacco materials or tobacco substitute contained in the snus bag.
  • the structure of the compacted zones and the non-compacted or to a lesser extent compacted zones not only can the permeability for flavors be adjusted, but also the bending stiffness, elongation, and strength can be influenced in the longitudinal and transverse directions, as well as by adjusting the three-dimensional
  • the surface structure specifically models the roughness and thus the feel of the bag when it is removed from the pack and when used orally.
  • the targeted adjustment of the fleece properties mentioned by locally compacting and solidifying the fleece can also be used to specifically influence the visual appearance of the fleece and thus produce visually diversified snus bags.
  • the diversified properties of the nonwoven material can be adjusted in a subsequent, less complex processing step, whereby the same nonwoven material can always be used as the starting product.
  • the nonwoven fabric is a chemically bonded nonwoven fabric.
  • the fibers are connected to one another at contact points via a binder applied to them.
  • the chemically bonded nonwoven fabric includes a chemical binder.
  • the chemical binder is an at least partially crosslinkable binder. When the binder is crosslinked, long-chain molecules are formed from monomers or short-chain molecules, which can be crosslinked with one another and form a polymer.
  • the compacted zones are permanently fixed in the compacted state by the same binder.
  • a binder can be used in the production of the nonwoven material, which chemically crosslinks into a thermoset when drying and connects the fibers to one another at the contact points, although the crosslinking only occurs partially, so that crosslinkable components still remain.
  • the pressure and temperature can be increased locally so that the binder crosslinks in the area of the embossing zones and forms a permanently compacted structure that has a certain wet strength.
  • the starting material for the nonwoven material can be, for example, that from pelytex & Co. KG, Willy-Pelz-Str. 2-4, 23812 Wahlstedt under the product name Nonwoven product marketed as “Nonwova CV 29/viv” can be used. Compacted zones and non-compacted zones or zones that are not compacted to a lesser extent are produced in the starting material by local pressing (embossing).
  • the nonwoven fabric is a mechanically bonded nonwoven fabric.
  • the nonwoven material is mechanically consolidated by needling or by water jets.
  • the mechanically bonded nonwoven is additionally provided with the binder.
  • the compacted zones are permanently held in the compacted state by interactions between the binder and fibers.
  • the bag has sealing seams in which overlapping areas of the nonwoven material are connected to one another by the binding agent.
  • sealing seams when sealing the sealing seams, pressure and/or temperature is exerted on the areas of the nonwoven material to be connected.
  • Binder of the non-woven material that has not yet bonded can be used to produce the sealing seams. These can be portions of the binder that have not yet bonded together in the compacted and/or non-compacted zones.
  • the nonwoven fabric comprises fibers of one or more of the following types of cellulosic fibers: viscose fibers, lyocell fibers or cotton fibers.
  • claim 1 states that the bag comprises a nonwoven fabric with compacted zones and zones that are not compacted or are compacted to a lesser extent.

  • the nonwoven fabric comprises several compacted zones and only a single non-compacted or to a lesser extent compacted zone or only a single compacted zone and several non-compacted or to a lesser extent compacted zones.
  • the nonwoven fabric comprises a plurality of separate compacted zones within a contiguous non-compacted or compacted zone to a lesser extent.
  • the zone that is not compacted or is compacted to a lesser extent forms a contiguous base area in which the compacted zones that are separated from one another are arranged.

  • the compacted zones and the zones not compacted or compacted to a lesser extent are arranged in a checkerboard pattern, with the compacted zones being arranged like the dark areas and the zones not compacted or compacted to a lesser extent being arranged like the light areas of the checkerboard pattern.
  • different sections of the nonwoven material have compacted and non-compacted zones or zones that are not compacted or are compacted to a lesser extent in different ways described above.
  • one side of the bag is designed in a different way than the other side.
  • the compacted zones and/or the non-compacted or to a lesser extent compacted zones have one or more of the following shapes: polygonal, circular, oval, cross-shaped, strip-shaped, wave-shaped (e.g. in the form of a sine, rectangular, Triangular or sawtooth oscillation).
  • the bag has a sealing seam running in the longitudinal direction on a large side in an overlapping area of the nonwoven fabric and sealing seams running in the transverse direction on the two transverse sides in the overlapping areas of the nonwoven fabric.
