- Figure 2 is a schematic diagram of a first end view of an aerosol generating article according to an example of the invention.
- Figure 3 is a schematic diagram of a first end view of a different aerosol generating article according to an example of the invention.
- Figure 4 is a schematic diagram of a side view of an aerosol generating article according to an example of the invention.
- Figure 5 is an exploded schematic diagram of a wrapper according to an example of the invention.
- lacquer refers to a coating, formed from polymers dissolved in volatile organic compounds, where the solvent is removed by evaporation, effecting curing of the polymers to produce a hard, durable finish.
- the lacquer may be an acrylic lacquer.
- the lacquer may be a styrene acrylic copolymer dispersion.
- the term“laminate” refers to a multi-layer structure in which the layers are fastened together to form a single body.
- the layers may be fastened with an adhesive, for example.
- the layers may be fastened by static interaction.
- the laminate structure might be formed by (partially) melting a first layer, contacting the first layer with a second layer and allowing the first layer to solidify. Any suitable mechanism for fastening the layers together including, but not limited to, the above examples, tying, sewing, screwing, nailing, bolting, hooking etc.
- each layer in the laminate structure may be fastened to the adjacent layer(s).
- the periphery of two layers may be fastened together with intermediate layers trapped in-between.
- peripheral layers may be referred to herein as the “innermost” and “outermost” layers. This refers to their location when the material is wrapped around an aerosol generating material.
- the wrapper comprises more than three layers. In some cases, the wrapper consists of three layers. In some cases, the wrapper may consist of a three layer laminate structure comprising the peripheral layers and the intermediate layer.
- FIG. 5 is a schematic illustration of a laminate wrapper according to the invention.
- the laminate structure (indicated by dotted lines) includes the peripheral layers 501,503 and the intermediate layer 502.
- the non-combustible material comprises a metal foil. In some cases, it may consist essentially of or consist of a metal foil. Suitably, the metal foil may comprise, essentially consist of or consist of an aluminium foil. The metal foil is a non-combustible material that can nevertheless act to conduct heat to the aerosol generating material in use.
- the metal foil may be less than about 100 pm, 50 pm, 20 pm, 10 pm or 8 pm thick. In some cases, it may be more than about 1 pm, 3 pm or 5 pm thick.
- the paper layer in the wrapper is a tobacco wrapping paper.
- a consideration when preparing aerosol generating articles such as tobacco heating products is that they should not produce an acceptable smoking experience if combusted, so that the user is not minded to burn the aerosol generating article. This is because the formulation of the aerosol generating material is not configured for combustion (and the aerosol that results from combustion may be less suitable for inhalation than the aerosol that results from heating but not burning that aerosol generating material, or than the aerosol which results from combustion of traditional cigarettes).
- non-combustible layer in the wrapper prevents the aerosol generating article from being burned and smoked as a conventional combustible cigarette.
- the inventors have found that the outer surface temperature of laminate wrappers described herein which have an intermediate layer comprising foil cool faster that comparative wrappers which comprise only paper. This eases handling for the user, and may be due to the higher thermal conductivity of the intermediate foil layer.
- non-combustible refers to a material that will not ignite or bum at temperatures normally associated with lighting (igniting) or burning of tobacco.
- a metal foil layer results in a wrapper that has a low porosity, reducing side stream air flow to the aerosol generating material. This further reduces the propensity to bum through limiting the oxygen levels at the aerosol generating material.
- peripheral surfaces with a coefficient of friction that is higher than a certain value is beneficial because this makes the wrapper easier to handle and process during the manufacturing process. It allows known machinery to be more readily employed. Specifically, this allows the garniture belt of an aerosol generating article making machine to drive the laminate wrapper through the garniture during the aerosol generating article manufacturing process.
- the lacquer may provide improved surface properties for the laminate wrapper.
- the lacquer may have a coefficient of friction that is sufficiently high to improve handling during manufacture. (Surfaces that are too smooth may slip in manufacturing machinery.)
- the lacquer aids in adhering the wrapper to itself when arranged around the aerosol generating material, since the lacquer retains adhesive on its surface and adheres more readily than the intermediate metal foil layer.
- the lacquer may provide resistance to corrosion of the metal foil layer.
- Metals such as aluminium may corrode, for example oxidise, in use or upon storage, and the presence of the lacquer may mitigation this corrosion.
- the paper in the innermost layer of the wrapper may have a basis weight of at least about lO g.m 2 , 15 g.m 2 , 20 g.m 2 or 25 g.m 2 to about 50 g.m 2 , 45 g.m 2 , 40 g.m 2 or 35 g.m 2 .
- Paper having a density in this range has a low porosity, which further reduces the propensity to bum through limiting the oxygen levels at the aerosol generating material.
- the innermost layer may also comprise a flavourant, which is transferred to the aerosol generating material when wrapped around the aerosol generating material and heated.
- the flavourant may comprise menthol.
- the paper in the innermost layer of the wrapper may be treated with one or more burn-retardant substances.
- the wrapper can be wound onto a bobbin core for use with standard cigarette makers that are fed from a single paper bobbin.
- one or more ventilation apertures may be formed in the wrapper. The ventilation apertures may provide airflow into the aerosol-generating article during use, the air forming part of the inhaled aerosol.
- the laminate wrapper may be formed using any suitable lamination technique.
- the layers may be adhered together.
- At least part of the innermost layer is disposed in contact with the aerosol generating material.
- the aerosol generating material comprises tobacco.
- the tobacco may be any suitable solid tobacco, such as single grades or blends, cut rag or whole leaf, ground tobacco, tobacco fibre, cut tobacco, extruded tobacco, tobacco stem and/or reconstituted tobacco.
- the tobacco may be of any type including, but not limited to, Virginia and/or Burley and/or Oriental tobacco.
- the aerosol generating material may be a rod of aerosol generating material.
- the term“rod” generally refers to an elongate body which may be any suitable shape for use in an aerosol generating assembly. In some cases, the rod is substantially cylindrical.
- the wrapper circumscribes at least the end of the rod that is distant from the user’s mouth in use (i.e. a distal-end rather than a mouth-end). This ensures that the non-combustible wrapper is disposed around the end of the rod which the user might try to ignite.
- the laminate wrapper circumscribes the rod over at least 25% of the rod length. In some cases, the wrapper extends over at least 35%, 40%, 45% or 50% of the rod length. As more of the rod is circumscribed, burning of the rod is more difficult.
- the wrapper does not extend over the entire length of the rod of aerosol generating material, resulting in cost savings. In some cases, the laminate wrapper extends over less than about 85%, 80%, 75%, 70%, 65% or 60% of the rod length.
- FIG. 1 illustrates an example aerosol generating article.
- the aerosol generating article 101 includes an aerosol generating material 103 which is wrapped by a laminate wrapper 102.
- this wrapper extends from the distal-end of the aerosol generating material over approximately 50% of the distance to the mouth- end of the aerosol generating material.
- the wrapper 102 comprises three layers, wherein the outermost layer comprises a lacquer, the innermost layer comprises paper and the intermediate layer comprises a non-combustible material.
- the wrapper may also be arranged over the distal-end of the aerosol generating material, so that the distal-end is completely enclosed in the wrapper.
- Figure 2 illustrates an example in which the wrapper 102 is wrapped around the circumference of the aerosol generating material 103. The distal-end of the aerosol generating article
- Figure 3 illustrates an alternative example of an aerosol generating article 101 in which the wrapper 102 completely encloses the distal- end of the aerosol generating article.
- the aerosol generating article may additionally comprise a filter and/or a cooling element.
- the cooling element may be arranged between the aerosol generating material and the filter.
- the filter may be arranged between the aerosol generating material and the cooling element.
- the filter and/or cooling element may be joined to the aerosol generating material by a wrapping material that circumscribes these components. This may, in some cases, be the laminate wrapper discussed above.
- the mouth-end of the aerosol generating material may be provided adjacent to one or more of a cooling element and a filter.
- a cooling element if present, allows vapour components to condense to form an aerosol and/or spaces the very hot parts of the apparatus from the user.
- a filter if present, may remove components from the fluid flow, affecting the chemical composition of the inhaled aerosol.
- Figure 4 illustrates an example of an aerosol generating article 101 which includes, in addition to the features of figure 1, a cooling element 104, a filter 105 and a mouth-end tube 106.
- the cooling element 104 and filter 105 may be arranged between the mouth-end of the aerosol generating material 103 and the mouth- end tube 106, so that flow from the aerosol generating material 103 passes through the cooling element 104 and filter 105 (or vice versa if the filter is arranged before the cooling element in the flow) before reaching the user.
- the example in Figure 4 illustrates a cooling element 104, a filter 105 and a mouth-end tube 106, one or more of these elements may be omitted in other examples.
- the mouth-end tube, if present, 106 may be formed of for example paper, for example in the form of a spirally wound paper tube, cellulose acetate, cardboard, crimped paper, such as crimped heat resistant paper or crimped parchment paper, and/or polymeric materials, such as low density polyethylene (LDPE), or some other suitable material.
- the mouth-end tube 106 may be a hollow tube. Such a hollow tube may provide a filtering function to filter volatilised aerosol generating material.
- the mouth-end tube 106 may be elongate, in order to be spaced from the very hot part(s) of the main apparatus (not shown) that heats the aerosol generating material.
- the cooling element 104 may comprise a monolithic rod having first and second ends and comprising plural through holes extending between the first and second ends.
- the through holes may extend substantially parallel to the central longitudinal axis of the rod.
- the through holes of the cooling element 104 may be arranged generally radially of the element when viewed in lateral cross- section. That is, in an example, the element has internal walls which define the through holes and which have two main configurations, namely radial walls and central walls.
- the radial walls extend along radii of the cross-section of the element and the central walls are centred on the centre of the cross-section of the element.
- the central walls in one example are circular, though other regular or irregular cross-sectional shapes may be used.
- the cross-section of the element in one example is circular, though other regular or irregular cross-sectional shapes may be used.
- the cooling element 104 may be substantially incompressible. It may be formed of a ceramic material, or of a polymer, for example a thermoplastic polymer, which may be an extrudable plastics material.
- the porosity of the element is in the range 60% to 75%. The porosity in this sense may be a measure of the percentage of the lateral cross-sectional area of the element occupied by the through holes. In an example, the porosity of the element is around 69% to 70%.
- the cooling element 104 may be formed from a sheet material that is folded, crimped or pleated to form through holes.
- the sheet material may be made, for example, from metal such as aluminium; polymeric plastics material such as polyethylene, polypropylene, polyethylene terephthalate, or polyvinyl chloride; or paper.
- the cooling element 104 and the filter 105 may be held together by a wrapper paper to form an assembly.
- the assembly may then be joined to the aerosol generating material by a further wrapper which circumscribes the assembly and at least the mouth end of the aerosol generating material to form the aerosol generating article 101.
- the aerosol generating article 101 is formed by wrapping the cooling element 104, the filter 105 and the aerosol generating material 103 effectively in one operation, with no separate tipping paper being provided for the cooling element and/or filter components (if present).
- one or more ventilation apertures may be formed in the aerosol generating article.
- the ventilation apertures may provide airflow into the article during use which forms part of the inhaled aerosol. It may be desirable to reduce airflow over the distal-end of the article to reduce the propensity to bum, and so the apertures may be formed nearer to the mouth-end of the article than to the distal-end.
- the ventilation apertures may be formed in the cooling element and/or filter, if present.
- the ventilation holes may be formed in a part of the article that is not wrapped in the non-combustible material. The inventors have established that cutting the non combustible material to form ventilation apertures may not be straightforward.
- the aerosol generating article may be arranged at least partially within a heating device to form an aerosol generating assembly which heats the article to generate an aerosol without burning.
- the article may be provided in an assembly with a fuel source, such as a combustible fuel source or chemical heat source, which heats but does not burn the aerosol generating material.
