Definitions

  • the present invention relates to filters for smoking articles.
  • the filtering material typically used in smoking article filters is a continuous tow of filamentary cellulose acetate plasticised with triacetin, which is gathered together to form a solid cylindrical rod of filtering material.
  • the solid cylindrical rod of filtering material may then be chopped into segments to provide individual filters.
  • Smoking articles such as conventional tobacco cigarettes are most commonly sold filter tipped.
  • a filter is attached to a rod of tobacco for example using one or more wrappers.
  • Marijuana smoking articles also known as "joints" are typically hand-rolled by the smoker.
  • Marijuana smoking articles do not typically include a filter comprising a cylindrical rod of acetate fibres. This is because the cellulose acetate is thought to excessively filter the active ingredients in marijuana smoke, for example CBD and/or THC.
  • Many marijuana smokers prefer to smoke marijuana smoking articles using a rudimentary smoker-prepared mouthpiece, commonly known as a "roach".
  • a roach is generally prepared by rolling a strip of cardboard at an angle to edge of the strip to form a conical mouthpiece.
  • Roaches do not significantly filter the marijuana smoke, and simply serve to prevent the heat from the smoke and/or burning particles in the smoke, e.g. burning
  • Marijuana particles from burning the smoker's lips whilst inhaling.
  • roaches include the significant amount of time for the smoker to prepare and an undesirable, untrustworthy and unreproducible crude-looking end appearance. Further, a roach does not provide the same firmness and/or experience as a manufactured cigarette filter. Accordingly, it is desirable to provide a refined, reproducible and trustworthy looking smoking article filter for use with a marijuana smoking article, either for use as a "roll- your-own" product, or for use in a manufactured filter tipped marijuana smoking article (e.g. cigarette).
  • the smoking article filter should prevent the smoker's lips from getting burnt and provide a reproducible, refined and trustworthy looking end appearance similar to that of a modern filter-tipped cigarette, whilst (like roaches) not significantly reducing the quantities of active ingredients in the marijuana smoke.
  • a mouthpiece or filter (e.g. for use in a smoking article) comprising a longitudinally extending (e.g. cylindrical) rod of filtering material including at least one longitudinally extending channel which extends along (e.g. through) the full length of the mouthpiece or filter.
  • the channel is surrounded by the filtering material along the full length of the mouthpiece or filter, but open at both ends.
  • a mouthpiece or filter (e.g. for use in a smoking article) comprising a longitudinally extending tubular rod of filtering material, the inner surface of the tubular rod of filtering material defining at least one (e.g. cylindrical) channel which extends along (e.g.
  • the longitudinally extending rod of filtering material may be of uniform cross-section along its full length (for example, being of uniform annular cross-section along its full length with the inner surface of the annular cross-section defining the channel).
  • the channel may be of uniform cross-section along its full length.
  • the channel may be of circular cross section, or other cross section (e.g. star- shaped, crescent shaped, flower-shaped, cross-shaped, X-shaped etc.)
  • the longitudinally extending rod of filtering material is of uniform outer dimension along its full length but the channel (which may or may not be of uniform cross-section along its full length) is helical about the longitudinally extending axis of the filter (e.g. the channel is in the form of a spiral about the longitudinal axis of the filter).
  • a helical channel increases the distance the marijuana smoke has to travel to reach the smoker's lips, thus providing a cool yet minimally filtered smoke. This advantage is not possible using existing roach technology.
  • the mouthpiece of the present invention may be referred to as a filter.
  • the level of filtration provided by the mouthpiece or filter may be varied according to the user's preference by varying the features of the mouthpiece or filter e.g. varying the diameter of the channel(s) present.
  • the level of filtration may be varied for example from providing no filtration to providing some filtration (e.g. 2-3%).
  • a mouthpiece or filter according to the present invention allows for smoke constituents to be focused towards the user and for cooling of the smoke as it travels to the user.
  • the mouthpiece or filter also may prevent embers or loose particulate matter from reaching the user's mouth and provides a grip point for the users fingers at the end of the product.
  • the mouthpiece or filter of the present invention may provide a unique visual experience for the user, for example by having a certain colour (e.g. red, yellow or green) or being capable of colour change during use of the product.
  • the mouthpiece or filter may provide a similar smoking experience (e.g. in terms of mouth-feel) to a cigarette due to the uniformity and firmness of the mouthpiece, and/or may make it easier to make the 'joint'.
  • the channel may be of circular, semi-circular (D-shaped), square, triangular, hollow star shaped, trilobal, pentagonal or cog-shaped cross-section, or of a cross-section in the shape of a logo or other pattern.
  • Mouthpieces or filters having a non-cylindrical channel, particularly those channel mouthpieces or filters having a complex and/or unsymmetrical cross-sectional profile may be of particular use in combatting anti- counterfeiting.
  • Channel mouthpieces or filters wherein the channel is not of uniform cross-section along its full length may also be of use in combatting anti-counterfeiting.
  • the channel which extends the full length of the mouthpiece or filter may be of uniform cross-section along the full length of the mouthpiece or filter.
  • the rod of filtering material is preferably of uniform outer dimensions along its full length (e.g. a cylinder of uniform dimensions along its full length).
  • Channel mouthpieces or filters may be manufactured by pulling a continuous bundle of cellulose acetate filamentary tow, optionally with triacetin already applied thereto, through a fix die having an external diameter equal to that of the desired external diameter of the mouthpiece or filter to be produced, the fix die including a protruding inner rod (or mandrel) extending through the die having a cross-sectional profile equal to that of the desired cross-section of the channel .
  • the filamentary tow When the filamentary tow is pulled through the die, it passes around the inner rod such that on exiting the die, a mouthpiece or filter is formed having a channel having a cross-sectional profile equivalent to that of the inner rod. Heated steam may be applied to the filamentary tow whilst the filamentary tow is in the die.
  • the heated steam may be applied via a duct in the die.
  • the heated steam may be for curing plasticizer applied to the filamentary tow (if present), allowing the mouthpiece or filter to maintain the shape of the die after exiting the die.
  • the inclusion of a channel extending along (e.g. through) the full length of the mouthpiece or filter allows a significant quantity of smoke (e.g. marijuana smoke, e.g. hemp smoke, e.g. oregano smoke) to pass directly to the smoker's mouth without being overly filtered.
  • the mouthpiece or filter also provides a refined end appearance and prevents the smoker's fingers and/or mouth from being burnt.
  • the mouthpiece or filter of the present invention may comprise a single channel.
  • the mouthpiece or filter of the present invention may comprise multiple channels.
  • the mouthpiece or filter may comprise from 1 to 20 channels, for example from 1 to 10 channels, for example from 2 to 10 channels, for example from 1 to 5 channels, for example from 2 to 5 channels, for example 3 channels, for example 1 channel.
  • the mouthpiece or filter of the present invention comprises multiple channels, these may be arranged in a number of different ways, for example in a triangular pattern, for example in a circular pattern, for example in a square pattern.
  • the use of multiple channels may further cool the smoke and prevent embers from reaching the user's mouth.
  • the longitudinally extending rod of filtering material when the mouthpiece or filter comprises a single longitudinally extending channel, the longitudinally extending rod of filtering material may be of uniform annular cross-section along its full length with the inner surface of the annular cross-section defining the channel. In another embodiment, when the mouthpiece or filter comprises 3 longitudinally extending channels, the longitudinally extending rod of filtering material may be of uniform cross-section along its full length with the channels arranged in a triangular pattern (see e.g. Figure 4).
  • the filtering material may be, for example, any of those materials (usually filamentary, fibrous, web or extruded) conventionally employed for tobacco smoke filter manufacture.
  • the filtering material may be natural or synthetic filamentary tow, e.g.
  • the filtering material may be a thermoplastic or otherwise spinnable polymer, for example polypropylene, polyethylene terephthalate or polyactide. It may be, for example, natural or synthetic staple fibres, cotton wool, web material such as paper (usually creped) and synthetic non-wovens, and extruded material (e.g. starch, synthetic foams).
  • the filtering material comprises cellulose acetate filamentary tow.
  • the fibres may be plasticised.
  • the filtering material may optionally include a plasticiser.
  • the formation of plasticised tow is well known in the art.
  • the plasticiser (which plasticises the fibres) may be, for example, triacetin, triethyleneglycol diacetate (TEGDA) or polyethylene glycol (PEG).
  • TAGDA triethyleneglycol diacetate
  • PEG polyethylene glycol
  • the fibres may be fibres of plasticised cellulose acetate tow.
  • the fibres may be cellulose acetate tow which has been plasticised with e.g. triacetin.
  • the filtering material may optionally include a binder material.
  • the filtering material may optionally include a water soluble binder material.
  • water soluble materials include water soluble polymer materials such as polyvinyl alcohol, polyvinyl pyrrolidone, polyvinyl ether, starches, polyethylene glycols and polypropylene glycols; blends of water soluble binders with plasticisers such as triacetin, triethyleneglycol diacetate (TEGDA), or polyethylene glycol (PEG); and hot melt water soluble binders in particulate form.
  • TOGDA triethyleneglycol diacetate
  • PEG polyethylene glycol
  • the filtering material may include an additive.
  • the additive may be a particulate additive.
  • the particulate additive may be any particulate additive suitable for use in a smoke filter - e.g. activated carbon, zeolite, ion exchange resin (e.g. a weakly basic anion exchange resin), sepiolite, silica gel, alumina, molecular sieves, carbonaceous polymer resins and diatomaceous earths.
  • the particulate additive may be a mixture of two, or more, materials.
  • the additive may be a pigment, for example a pearlescent pigment or a thermo-chromatic pigment,
  • the additive may include a smoke modifying agent (for example a flavourant).
  • a smoke modifying agent for example a flavourant
  • This may be any smoke modifying agent (e.g. flavourant) known or suitable for use in a smoking article such as a cigarette, for example flavourant such as menthol, spearmint, clove oil etc.
  • the flavourant may be any flavouring agent known for use in smoke filters.
  • the flavouring agent may be menthol, spearmint, peppermint, nutmeg, cinnamon, clove, lemon, chocolate, peach, strawberry, vanilla etc.
  • the smoke modifying agent (flavourant) may be applied to the filtering material in liquid form.
  • the smoke modifying agent (flavourant) may be liquefied prior to application to the filtering material, for example by heating above the melting point, for example by mixing with a liquid carrier.
  • the smoke modifying agent (flavourant) may be applied to the filtering material prior to the filtering material entering the die, for example immediately before entering the die.
  • the smoke modifying agent (flavourant) may be mixed with and applied with a plasticiser, for example by spraying the mixture of smoke modifying agent (flavourant) and plasticiser onto the filtering material.
  • a preferred smoke modifying agent (flavourant) is menthol.
  • the additive may be sepiolite granules to which menthol flavourant has been applied.
  • the filtering material may include fully enclosed (e.g. embedded) pocket(s) of additive embedded therein.
  • the additive may be a particulate additive such as activated carbon (see above), which is for example enclosed within the filtering material as a discrete pocket or pod of particles of particulate additive which is substantially separate from, and fully enclosed within, the filtering material.
