DESCRIPTION

Rolling paper for a smoking article

technical field

The present invention relates to a rolling paper for a smoking article having a low ignition propensity and a smoking article comprising a rolling paper having a low ignition propensity.

technical background

When a burning smoking article is left on furniture and equipment, such as a sofa or bed, it could start a fire. To avoid this, various strategies are known from the prior art to cause a smoking article to self-extinguish. These types of smoking articles are generally known as "low igniting propensity" smoking articles. However, it is not desirable to have a smoking article that self-extinguishes while a smoker is using it.

US 2013/104,915 discloses a cigarette paper providing a cigarette made therefrom with self-extinguishing properties, wherein the base paper has a CO ² diffusivity of less than 0.35 cm/s and the cigarette comprises at least one discrete zone, wherein this zone is perforated and has a higher air permeability than the air permeability beyond the perforated zone.

Document US 2016/198,761 refers to a cigarette paper with self-extinguishing properties that has treated areas, on which a composition containing filler particles or a mixture of filler particles is applied, in which the diffusion capacity in treated areas is less than in an untreated area of the cigarette paper. In this regard, at least 20% by weight of the filler particles in the treated areas is formed by a filler with a laminated shape, a filler with a scalenohedral crystal structure, a filler with a rhombohedral crystal structure, or a filler with a cubic shape.

In order to prevent a fire and to suppress secondhand smoke, Japanese Utility Model No. 3049857 discloses a cigarette in which the length of the tobacco rod is half that of the normal cigarette. Also Japanese Patent Application KOKAI No. 7-327654 discloses a cigarette in which the length of the tobacco rod is decreased to 1 to 1.5 cm to prevent fire and to suppress secondhand smoke. These cigarettes having a shorter than usual tobacco rod provide a considerably smaller number of puffs than that provided by the commercially available cigarette.

The problem of the present invention is to provide a rolling paper for a smoking article which has a low propensity for ignition and a reduced impact on taste.

US 2012/0227754 discloses a smoking article including a smoking cylinder made using a paper rolling stock having an additive material applied thereto as a pattern. The rolling paper includes at least one region coated with an additive material coating formulation having a porosity of less than about 20 CORESTA and a diffusion capacity of no greater than 0.2 cm/s. The coated region is a base sheet having a porosity of greater than about 120 CORESTA and a diffusion capacity of at least 1.7 cm/s.

Brief description of the invention

The inventors have discovered that by providing a rolling paper for a smoking article with a plurality of burn-suppressing regions and a certain diffusion capacity ratio between the burn-suppressing regions and the base paper, i.e., the non-smoke suppressive regions, it is possible to obtain a low ignition propensity smoking article with a reduced impact on taste.

A first aspect of the present invention relates to a rolling paper comprising a base paper, wherein the base paper comprises a plurality of burn-suppressing regions that are provided spaced from each other, wherein the diffusion capacity ratio between the burn suppressing regions and the base paper, ie, the non-burn suppressing regions, is in the range of 5% to 35%.

In another aspect of the present invention, there is disclosed a smoking article comprising a charge of smoking material surrounded by a rolling paper in accordance with the first aspect of the invention. The smoking article is in particular a low ignition propensity smoking article.

Additional aspects and embodiments of the invention are disclosed in the dependent claims and may be drawn from, without limitation, the following description and examples.

figures

The accompanying drawings are intended to illustrate embodiments of the present invention and convey a further understanding thereof. In connection with the description, it serves as an explanation of concepts and principles of the invention. Other embodiments and many of the advantages indicated in connection with the drawings can be obtained.

Fig. 1 is a partially broken, schematic perspective view showing an example of a cigarette that is wrapped with a cigarette paper having band-shaped burn-suppressing regions according to an embodiment of the present invention.

The cigarette 10 has a tobacco rod 11 consisting of a tobacco filler 13 which is wrapped with a rolling paper 12 of the present invention in the form of a column. A normal filter 15 can be attached to the proximal end (ie, the rear end in the inhalation direction) 11b of the tobacco rod 11 using tipping paper 14 according to a conventional method.

A plurality of band-shaped burn suppressing regions 122, which are coated as will be explained in the following description, are formed on one of the surfaces of the base paper 121 constituting the rolling paper 12 of the present invention. These band-shaped burn suppressing regions 122 are formed spaced apart from each other in the circumferential direction of the tobacco rod 11.

Non-burn suppressor regions 123 are formed between adjacent band-shaped burn suppressor regions 122. Since the regions 123 are made up of a part of the base paper 121, they can be burned in a normal smoking state. Therefore, the regions 123 each act as a non-burn suppressor region. For example, the band-shaped burn suppressing regions 122 may each have a width of 1 to 6 mm in the circumferential direction. The distance between adjacent burn suppressor regions 122 may be from 2 to 20 mm.

In the cigarette shown in Fig. 1, a non-smoke-suppressing region 124 may be provided to the region that covers a distance d from the tip 11a of the base paper 121.

Fig. 2 is a partially broken, schematic perspective view showing an example of a cigarette that is wrapped with a cigarette paper having annular stripe-shaped burn-suppressing regions according to another embodiment of the present invention.

Cigarette 20 is similar in structure to cigarette 10 shown in Figure 1, except for the structure of the burn suppressing regions in the rolling paper. Therefore, in Fig. 2, an identical reference number is assigned to the same element as the constitutional element in Fig. 1, and explanation thereof is omitted.

In the cigarette 20 shown in Fig. 2, a plurality of annular stripe-shaped burn-suppressing regions 211 are formed on the base paper 121 of the rolling paper 21 enclosing the tobacco filler 13, defining burn-suppressing regions. These annular strip-shaped burn-suppressing regions 211 are formed spaced apart from each other in the longitudinal direction of the tobacco rod 11.

Non-burn suppressor regions 212 are formed between adjacent annular fringe-shaped burn suppressor regions 211. Since the non-burn suppressing regions 212 are made up of a part of the base paper 121, they can burn in a normal smoking state. Therefore, the regions 212 each act as a non-burn suppressor region, like the regions 123 of FIG. 1. For example, the annular fringe-shaped burn suppressor regions 211 may each have a width of 4 to 7 mm in the longitudinal direction. The distance between adjacent burn suppressor regions 211 may be from 18 to 25 mm.

Detailed description of the invention

Unless otherwise defined, the technical and scientific terms used in this document have the same meaning as that usually understood by a person skilled in the art to which this invention pertains.

All values given in the present disclosure are to be understood supplemented by the word "approximately", unless otherwise clear from the context.

Smoking articles mentioned in this document are not particularly limited and may be, for example, cigarettes, cigarillos or the like. They typically have a generally cylindrical tube-shaped configuration and include a charge, roll, or column of smokable material, such as shredded tobacco (for example, in a cut filler form), that is surrounded by a paper wrapper that forms a called "tobacco cylinder". A cigarette or cigarillo usually also has a cylindrical filter element aligned in end-to-end relationship with the tobacco rod. The filter element may comprise, for example, a stopper of cellulose acetate tow, and the tow is bounded by a wrapping material known as "stop wrap". Typically, the filter element is attached to one end of the tobacco rod using a rolling material known as "tip wrapper". The filter element enclosed by the nozzle wrap is known as the "nozzle element".

As used herein, "wt%" is meant as percent by weight, based on the dry weight of the base paper, unless otherwise explicitly specified. In the present disclosure, all amounts given in % by weight in a particular embodiment add up to 100% by weight. The weight percent, thus, is calculated by dividing the mass of each component by the dry mass of the base paper.

As used herein, a "low igniting propensity" smoking article is one that has been designed so that it is less likely than a conventional cigarette to ignite furniture and equipment, for example, soft furnishings such as a sofa or mattress. . Ideally, a low ignition propensity smoking article will continue to burn when freely suspended such as in an ashtray holder or when held in the hand without puffing ("free burn"). The tendency of a cigarette to go out during free burn is called "self-extinguishment".

The ability of a smoking article to go out or generate enough heat to continue burning and thus potentially cause ignition of bedding or upholstered furniture (referred to as LIP) can be measured by any suitable method. In the present invention this is done in accordance with ISO 12863:2010.

The probability of a smoking article going out while burning in open air (referred to as PHASE) can be measured by any suitable method. In the present invention this is done in accordance with ISO 12863:2010.

The TNCO levels mentioned in this document represent the levels of tar, nicotine and carbon monoxide and can be measured by any suitable method. In the present invention this is done in accordance with ISO 3308:2012.

The symbol "CU" in this document indicates the CORESTA air permeability unit which is commonly used in paper specifications by designers of smoking articles. The CORESTA air permeability unit is defined as: "the volumetric flow rate of air in cubic centimeters per minute (cm3/min) passing through a 1 square centimeter (cm2) sample of substrate at an applied pressure difference of 1 kilo-Pascal (kPa)" and is measured in accordance with ISO 6565:2011.

The number of puffs on a smoking article can be measured by any suitable method. In the present invention this is done in accordance with ISO 3308:2012.

The diffusion capacity of a rolling paper is measured in the present invention according to the recommended method of CORESTA n.277 (CRM n.277) of April 2014.

The present invention relates to a rolling paper for a smoking article comprising a base paper, wherein the base paper comprises a plurality of burn suppressing regions which are provided spaced from one another, wherein the ratio of diffusion capacity between the scorch suppressing regions and the base paper is in the range of 5% to 35%. By providing this diffusion capacity relationship between the burn-suppressing regions and the base paper outside the burn-suppressing regions (non-burn-suppressing regions) it is possible to provide a low ignition propensity smoking article with reduced impact on the smoke. taste. The rolling paper is formed from a base paper with burn suppressing regions provided thereon. Since the regions of the rolling paper that are outside of the burn suppressive regions are to be considered non-burn suppressive regions, the latter being the same as the base paper, the present application uses the terms "non-burn suppressive regions" and " base paper" interchangeably.

In certain embodiments of the present rolling paper, the diffusion capacity ratio between the burn-suppressing regions and the non-burn-suppressing regions, i.e., the base paper, is in the range of 10% to 35%, or from 15% to 35%, or from 5% to 30%, or from 10% to 30%, or from 15% to 30%, or from 10% to 25%, or from 15% to 25%.

In a particularly preferred embodiment, the diffusion capacity ratio between the burn-suppressive regions and the non-burn-suppressive regions is in the range of 9% to 17%. It has been found that the impact on flavor is particularly reduced in this range while the rolling paper shows good LIP and PHASE performance.

Burn suppressing regions may be provided on a surface of the base paper or embedded within a matrix of the base paper. The plurality of scorch suppressing regions may be provided on a same surface of the base paper. Alternatively, one or more of the plurality of scorch suppression regions may be provided on a first surface of the base paper and the remainder of the plurality of scorch suppression regions may be provided on an opposite second surface of the base paper.

The shape and amount of these burn suppressing regions are not further limited and may vary according to the specific requirements of the smoking article. In certain embodiments, suppressor regions of burnt are in a form of bands. In one embodiment, all the bands are parallel to each other. In another embodiment, at least two bands are not parallel to each other.

In certain embodiments of the present smoking article comprising a rolling paper, when the rolling paper is wrapped around a tobacco rod, the burn suppressing regions are in the form of bands extending in a longitudinal direction of the tobacco rod. and which are spaced apart from each other in a circumferential direction of the tobacco rod.

In certain embodiments of the present smoking article comprising a rolling paper, when a tobacco rod is wrapped by the rolling paper, the burn-suppressing regions are in the form of curved annular fringes extending in a circumferential direction of the cylinder. of tobacco and which are spaced apart from each other in a longitudinal direction of the tobacco rod.

In certain embodiments of the present rolling paper, the diffusion capacity of the base paper, that is, the non-smoke suppressive regions, is from 1.0 to 2.0 cm/s, for example, from 1.0 to 1 .8 cm/s or, for example, 1.2 to 1.6 cm/s or, for example, 1.2 to 2.0 cm/s or, for example, 1.2 to 1.8 cm/s or eg 1.2 to 1.6 cm/s or eg 1.4 to 2.0 cm/s or eg 1.4 to 1.8 cm/s or eg 1.4 to 1.6 cm/sec.

In certain embodiments of the present rolling paper, the diffusion capacity of the burn suppressing regions is 0.10 to 0.35 cm/s or, for example, 0.15 to 0.35 cm/s or, for example, from 0.20 to 0.35 cm/s or, for example, from 0.10 to 0.30 cm/s or, for example, from 0.15 to 0.30 cm/s or, for example, from 0.20 to 0.30 cm/s or eg 0.10 to 0.25 cm/s or eg 0.15 to 0.25 cm/s or eg 0.20 to 0.25 cm/ yes

These scorch suppressing regions may contain additives that reduce the diffusion capacity of the base paper. Additives that can be applied to the wrapper can be any of those used in the art to reduce the ignition propensity of smoking articles.

In certain embodiments of the present rolling paper, the burn suppressing regions in the rolling paper contain at least one additive that reduces the diffusion capacity of the base paper. Additives are optionally selected from the group consisting of alginates, polyvinyl alcohol, polyvinyl acetates, including partially hydrolyzed derivatives and copolymers, modified and unmodified starches, cellulose derivatives, such as carboxymethylcellulose, ethylcellulose, hydroxymethylcellulose, and combinations of the themselves.

According to certain embodiments, the balance up to 100% by weight of the dry weight of the base paper is essentially filler and fibrous material.

In certain embodiments of the present rolling paper, the basis weight of the base paper is from 20 to 26 g/m2, for example, from 21 to 24 g/m2, or, for example, from 23 to 25 g/m2, for example. , 24g/m2. By providing a base paper with a basis weight in these ranges it is possible to obtain a desired opacity of the rolling paper while controlling the CO level.

In certain embodiments of the present rolling paper, the fibrous material is a cellulosic fibrous material.

The present invention further relates to a smoking article comprising a rolling paper as in the embodiments described above and in which the rolling paper surrounds a charge, roll or column of smoking material to form a cylinder of tobacco.

In certain embodiments of the present smoking article, when rolling paper is wrapped around a tobacco rod, the burn suppressing regions are in the form of bands extending in a longitudinal direction of the tobacco rod and spaced apart from each other. in a circumferential direction of the tobacco rod.

In certain embodiments of the present smoking article, when a tobacco rod is wrapped in rolling paper, the burn suppressing regions are in the form of curved annular fringes extending in a circumferential direction of the tobacco rod and spaced apart. with each other in a longitudinal direction of the tobacco rod.

The present invention relates to a rolling paper comprising a plurality of burn suppressing regions which are provided spaced apart from one another on a surface of the rolling paper, wherein the ratio of diffusion capacity between the burn suppressing regions and non-suppressor regions of burning is in the range of 5% to 35%.
