SIMULATED CIGARETTE
[001] The present invention deals with a simulated cigarette, which cigarette comprises a housing that has a shape and size generally similar to that of a cigarette; a reservoir of inhalable composition, inside the housing; an outlet valve controlling the flow of the reservoir; an outlet passage from the outlet valve to an outlet of the housing from which a user inhales the composition. A simulated cigarette like this will subsequently be referred to as "of the described species".
[002] Simulated cigarette of the described species is described in publications WO 2009/001078 and WO 2009/001082, both in the name of the same Applicant. [003] Such documents describe a simulated cigarette device that is refillable in combination with a refill pack that has the size and shape of a cigarette pack. User removes the simulated cigarette from the pack and holds it against an outlet hole in the pack to refill it. It is designed to mimic the action of removing a real cigarette from a pack. By replicating the act of smoking, the device is more likely to obtain consumer acceptance. [004] However, the simulated cigarette device described in these two publications and, in reality, the similar cigarette devices described in other documents, such as US 4,393,884 and DE 4030257, are simply cylindrical plastic tubes.
[005] The present invention aims to provide a simulated cigarette device, which more closely resembles the physical sensation of a real cigarette.
[006] According to a first aspect of the present invention, a simulated cigarette of the described species is characterized by the fact that the housing is adjacent to the outlet end and has a deformable material on its external periphery.
[007] Such deformable material is capable of being squeezed or flexed by a smoker's index finger and thumb. This is an important aspect for a smoker and is part of the behavioral cycle of the smoking ritual. The first aspect of the present invention, therefore, provides a tactile feel similar to a conventional cigarette. The deformable material also provides a more realistic smoking experience for the user when it comes to inhalation. Users typically wrinkle inhalation devices with their lips or teeth, so it is advantageous to make the material against which they press accordingly deformable.
[008] As well as providing increased comfort, the deformable material can also be used to affect the flow characteristics of the inhalable composition. Preferably, deformable material is configured to be deformable with respect to that outlet passage, to change the flow characteristics of the outlet passage. With a deformable material of this type, the user can interrupt the flow of inhalable material, giving rise to vortices that will change the reservoir supply. This mimics the way in which smokers modify the supply of a conventional tobacco cigarette by squeezing the filter to reduce the pore size, thereby modifying the flow of smoke, therefore. This allows the user to modify the flow by narrowing the outlet passage and thereby accelerating the flow speed.
[009] In order to further increase the control that is exercised by a user, the outlet valve is preferably a valve activated by breathing, which is triggered by an air flow through the housing in an actuation passage parallel to the flow through the outlet passage and in which the deformable material is positioned so that it is deformable within the housing to a position where it affects the flow through at least one of the actuation passage and the exit passage, in order to affect the dosage of inhalable composition that a user receives from the cigarette.
[0010] If the user restricts the actuation passage, the suction force required to open the valve increases, while restricting the outlet passage increases the flow speed. This is an important adaptive behavioral mode for smokers, since, when they desire a deeper inhalation, usually at a peak of desire, they can modify the suction chamber through this action and modestly increase the speed of flow and, therefore, the absorption speed for the lung, allowing sophisticated control of flow characteristics. Additionally, if the user exerts less suction force than usual and restricts the chamber, the device can work in the opposite way, creating a limitation in the breathing force exerted on the breathing activation system and, therefore, limiting the opening valve and thus the flow rate by the user. Thus, allowing distortion of the flow path, similar to a tobacco cigarette, a more sophisticated control of the flow characteristics is allowed.
[0011] The deformable material can be elastomeric or it can be a flexible film, containing a fluid or gel.
[0012] When the deformable material includes liquid or gel, as another enhancement of the invention, it can be supersaturated and arranged to come into contact with nucleation sites by hitting the cigarette, to form crystals and undergo an exothermic reaction.
[0013] This can produce a warming sensation at the tip of the cigarette, which the user will find pleasant and, again, will replicate the heating effect of a real cigarette by pulling smoke through the filter.
[0014] As the cigarette device is designed to be refilled numerous times, there is preferably a portion of compartments containing liquid or gel, which are separately actionable to produce an exothermic reaction.
[0015] In addition, or as an alternative to using the exothermic reaction in such a way as to provide a warm sensation adjacent to a cigarette nozzle, the cigarette can be configured to direct the heat produced inward in order to heat the inhalable composition in the exit passage. [0016] This forms a second aspect of the present invention, which can be defined, in the broadest sense, as a simulated cigarette of the described species, further comprising a chemical heater provided adjacent to the outlet passage and arranged to be activated to undergo a reaction exothermic to heat the inhalable composition when it moves along the outlet passage.
[0017] The generation of heat in a simulated cigarette is known, for example, in EP 1,618.83 and WO 2009/155957. However, in these cases, heat is used to vaporize the composition. In this second aspect of the present invention, the inhalable composition is released from a reservoir and is subsequently heated by a heater.
[0018] The generation of heat in a simulated cigarette is known, for example, from EP 1,618,803 and WO 1009/155957. However, in these cases, heat is used to vaporize the composition. In this second aspect of the present invention, the inhalable composition is released from a reservoir and is subsequently heated by a heater.
[0019] The inhalation composition is released from the reservoir and will generally be cold. It is heated, to a certain extent, by the surrounding housing, when it moves around the outlet passage and, if present, by dilution of air from the actuation passage. However, if the device is used repeatedly, the mouthpiece itself can become cold to the touch. This can be avoided by heating the mouthpiece, which also has a beneficial effect on the entire inhalable composition flowing through the mouthpiece.
[0020] Preferably, the outlet valve is at least 4 mm from the outlet. This allows sufficient time for the inhalable composition to mix with the ambient air, to allow the heating effect mentioned above. This allows sufficient time for the inhalable composition to mix with the ambient air, to allow the heating effect mentioned above.
[0021] Preferably, the heater is provided with a gel or liquid that is supersaturated and that is willing to come into contact with the nucleation sites when hitting the cigarette, to form crystals and undergo an exothermic reaction.
[0022] When the cigarette device is designed to be refilled numerous times, there are preferably a plurality of compartments containing liquid or gel that are separately actionable to produce an exothermic reaction. These components are preferably provided by breakable microcapsules.
[0023] According to a third aspect of the present invention, a simulated cigarette of the described species is wrapped in a wrapper comprising an adhesive layer to stick to the housing, a layer of paper or paper type and a polymeric film to cover and protect the paper or paper layer or paper type.
[0024] In the prior art mentioned above, all simulated cigarettes of this type have only a plastic housing as they are designed to be durable. US 2004/0003820 describes a substitute cigarette with a chamber lined with scraped release coated paper, which is scratched with a wire brush to release a cigarette-like aroma. This document describes that the vessel is lined or lined with a white material, like paper, for improved realism, but there is no indication of the underlying material of the housing or how it is implemented. JP2010 / 33663 describes an inhaler containing a string of capsules. These are crushed by the user's finger to release their contents for inhalation. The device is covered with a paper-like material, since it is required to be deformable to crush the capsules.
[0025] The third aspect of the present invention more accurately replicates the feel of a real cigarette. In addition, it is suitable for the arrangement described in WO 2009/001078 that is designed to be refilled only a relatively small number of times, so that longevity is less of an issue. The polymeric film is able to protect the paper when the time for which it is used, although for less than the prior art above, is still significantly longer than a real cigarette or the devices of US2004 / 0003820 and JP 2010/035663 . [0026] Preferably, the wrap is hydrophobic, so that it does not absorb moisture from the user's mouth, the environment or the filling process. The wrap is preferably an easy to clean paper. It is also preferably flame retardant in case of hazardous or wrong ignition. Preferably, the wrap is provided with a flavor (e.g., menthol) and / or an antibacterial agent.
[0027] One such example of a wrap is a crown-treated, coextruded and biaxially oriented propylene, located with an acrylic-based adhesive. The adhesive is a floating acrylic based adhesive, comprising acrylic esters copolymerized with acrylic acid.
[0028] This is laminated on supercalendered icing paper, which provides the image and texture of a paper wrapper, where the transparency is around 30-60%, most preferably 45%. A compatible ink, preferably a raw material consisting of an acrylate mixture, which in its cured form finished in an acrylate polymer contains very little residual monomer, such as to improve the chemical stability of the system. Such a system can also be impregnated with a Silver Ion spray coating on top of the icing paper, to limit any microbial activity through continued use and the extreme tip can be sprayed with a compatible fire retardant material before the adhesive layer and polypropylene extruded applied.
[0029] Additionally, a laminate is fitted over the system to improve the stability and duration of use. A highly resistant acrylic adhesive is used to fix the laminate underlying the icing paper on the plastic chassis of the inhaler, so that it remains in a fixed position without spiraling or unwinding during the assigned shelf life. Such a system should incorporate a co-extruded and biaxially oriented crown-treated polypropylene of as low a density as possible, without compromising strength, in order to improve the stability of wrapping fixation.
[0030] The system must meet the standards established under ISO 10993, when referring to the biocompatibility of components. As such, the plastic coating must satisfy a safety test guideline under European Pharmacopeia, in order to ensure compatibility in transient oral mucosal contact, with adhesive layers ensuring compatibility with European food directive laws, FDA 175.105 and German recommendations XIV , as published by BR. This construction must also be classified as a safety product according to the material description provided by EC directive 92/59, article 2 (b), which will ensure safety for repeated use.
[0031] The wrap can be used by itself, but it is particularly advantageous when used in combination with the deformable material of the first aspect of the present invention and / or the heater of a second aspect of the present invention, since the overall effect more strictly resembles a real cigarette.
[0032] In all aspects of the invention, the reservoir is preferably pressurized and refillable. The refill is preferably carried out through a refill valve at the end of the cigarette opposite the outlet.
[0033] Examples of a simulated cigarette, according to the numerous aspects of the present invention, are now described with reference to the accompanying drawings, in which: Fig. 1 is a cross section of a simulated cigarette; Fig. 2 is an exploded view of the simulated cigarette;
Figs. 3A, 3B, and 3C are seen in perspective from alternative deformable members; and Fig. 4 is a cross section of the example in Fig. 3A.
[0034] The device has a housing 1 composed of a main chassis 2 and a closing element 3, as shown in Fig. 2. This is held in position by the label 4. Inside the housing, there is a reservoir 5 containing the inhalable composition . This is preferably pressurized but could also operate with a non-pressurized reservoir in combination with a Venturi nozzle, to generate increased suction force on that reservoir. It can be refillable, as described in WO 2009/001082, through the refill valve 6, or the device can be a single use device or it can be arranged so that the reservoir 5 is a refillable component.
[0035] The breath-activated valve 7 is positioned between an outlet end 8 and the reservoir 5. The breath-activated valve is arranged so that when the user sucks at the outlet end 8, the breath-activated valve 7 becomes opens to allow the inhalable composition of reservoir 5 to be inhaled.
[0036] The housing downstream of valve 7 has two passages. The first of these is the suction passage 9, which communicates with a chamber 10, as will be described in more detail below. The suction passage and the composition passage are located in the outlet passage 13, which leads to the outlet end 8.
[0037] A deformable tubular nozzle 14 is provided between the reservoir 5 and the composition passage 11. The element is selectively deformable between the open and closed configurations by a mechanism as described below.
[0038] This mechanism comprises a reed 15 and a membrane 16 hingedly fixed. The hingedly fixed vane has a pivot 17 at the end closest to the outlet end 8 and a central reinforcement rib 18, running along its length and tapering away from the outlet end. Near the intermediate point, the reed 15 is provided with a recess 19 to receive a spring 20, which tends it to the closed position shown in Fig. 1. Below the recess 19 there is a claw 21 having a triangular cross section, which is configured to apply the force provided by the reed 15 to the nozzle 14 through a narrow area (although the nozzle is shown in Figure 1 in its uncompressed, open state, while in use, with the reed in this position, it deforms the nozzle to seal the reservoir). The reed 15 is supported by the diaphragm 16, which is sealed in the housing at its ends 22, 23.
[0039] An entrance 24 is provided into the chamber 10, while the side under the membrane 16 is opened to atmospheric pressure when the leak path passes through the housing 1, which is not shown in the drawings, since it is not shown in the plane of Figs. 1 and 2.
[0040] When a user sucks at the outlet end 8, air is sucked through the inlet 24 through the chamber 10 and out of the suction passage 9, thereby decreasing the pressure inside the chamber 10. This causes the reed 15 is raised against the action of the spring 20, deforming the diaphragm and raising the claw 21, to allow the deformable nozzle 14 to open, thereby allowing the inhalable composition of the reservoir 5 along the composition passage 11 into the outlet passage 13, where it mixes with the suction air. The degree of suction applied by the user will determine the extent to which the reed 15 moves and, therefore, the amount of composition the user receives. As soon as the user stops the suction, the atmospheric pressure will return to the chamber 10 and the spring 20 will push the vane down, thereby holding the nozzle 14 closed. [0041] The simulated cigarette described so far is generally as described in WO 2011/015825.
[0042] The housing 1 is provided at the outlet end with a generally annular recess 30 surrounding the outlet passage 13. Within this annular recess there is a deformable member 31 which, in situ, is flush with the surface of the housing 1, as shown in Figure 1. The deformable material 31 can be an elastomeric member, or it can be a thin-walled capsule, containing a liquid or gel that is described in more detail below. An annular edge 32 is present at the outlet end of the cigarette. It may be thinner than the border shown or it may not be present at all.
[0043] The deformable material 31 is generally positioned in the area that would be occupied by the filter of a conventional cigarette. Thus, the user is able to squeeze the end of the cigarette so that he squeezes the cigarette filter and keeps this end of the cigarette in his mouth and, in both cases, obtains a tactile sensation comparable to that of a real cigarette. [0044] Furthermore, the housing 1, in the vicinity of the outlet passage 31, is provided with a pair of diametrically opposed openings 33 and, as shown in Fig. 1, the deformable material 31 is arranged to bulge through them to design into the outlet passage 13. When the user presses on the deformable material, the degree to which the deformable material bulges into the passage 11 is varied. If the user presses on top of the deformable material 31 (with reference to the orientation shown in Fig. 1), he will restrict the flow through the suction passage 9, with the effect that the user will need to suck more heavily on the device to obtain the profile desirable inhalation. If he presses on the bottom of the deformable material 31, he will restrict the flow through the composition passage 11 with the effect that, if the valve is fully open, the flow speed will increase and speed up the supply route. Pressing at the top and base of the deformable member 31 simultaneously will increase the resistance and will need to suck harder on the device, but also, due to the nature of the construction of the composition passage 11, it will increase the flow and speed of the supply. This is a useful detail for smokers who want to increase the absorption rate when they experience a peak of craving. Thus, a user is able to self-regulate the flow of the inhalable cigarette composition, much like they are able to do with a conventional cigarette squeezing into the filter.
[0045] As well as providing tactile benefits and the ability to regulate flow, the deformable material 31 can also be designed as a heater.
[0046] As mentioned above, the deformable member 31 may contain liquid or gel. This can be an acetate and, preferably, sodium acetate, which is supersaturated. This can be encapsulated within microcapsules having a polymeric or cellulosic capsule. If there are about 20 such microcapsules, the device can be reused numerous times, each time breaking a small number of capsules. Within the deformable material 31 and surrounding the internal wall there is a layer, disc or film of ferrous metal or other that provides a greater area of reactive surface. When the user hits the outer wall of the deformable element 31, just as a smoker is used to doing to release ash that has accumulated in the tip of the cigarette, sodium acetate crystals are released into the solution, which then act as local nucleation. This causes the solution to suddenly crystallize, releasing energy and thereby creating a heating effect on the surrounding material, which the user can perceive. This heat can be controlled to ensure that the temperature is pleasant and warm and does not approach higher temperatures, which may impact the integrity of the device. In order to last through various refills of the device, the deformable member 31 can be composed of multiple layers or compartments 34, each individually connected to separate solutions and ferrous metals. It is possible that the outer wall of the deformable member 31 could be a good insulator, allowing minimal heat to be conducted out of the device, so that the heat is instead directed inward to heat the flow through the overpass 13 .
[0047] Alternative designs of deformable element 31 are shown in Figs. 3A - 3C and 4. In Figures 3A and 4, each of a plurality of frangible balls 35, containing acetate, is positioned on a ferrous disc 36, which provides the nucleation sites. Pressure on the external wall of the deformable limb breaks some of the frangible balls, so that the acetate comes into contact with the ferrous disc, initiating nucleation and causing an exothermic reaction.
[0048] In Fig. 3B, compartments 34 are filled with calcium powder and frangible balls 37 containing water are arranged along the length of each compartment. Again, the pressure on the deformable member 31 breaks the balls 37 and the water and calcium chloride react exothermically.
[0049] In Fig. 3C, each compartment 34 contains an elongated ferrous disc 38, the compartment filled with acetate. In this case, pressure on the deformable member 1 causes a sudden “instant” deformation of a disc 38 to trigger nucleation.
[0050] Other sources of chemical heating, for example, may include but are not limited to using an in situ combination of calcium chloride and a reservoir containing pure distilled water. Calcium chloride is separated from water by a film or a diaphragm which, when beaten or pushed, loses the integrity of its shell and allows the water to dissipate and, therefore, causing an exothermic reaction to occur. For use in a multiphase manner, distilled water can be manufactured into microcapsules, pellets or spheres enclosing a polymeric or cellulosic wrap, which are no more than 2 mm in diameter. These microcapsules can be located inside the chamber and evenly distributed around a surrounding layer or finely divided calcium chloride powder. When the user squeezes the deformable member 31, the nozzle element, pressure is applied to the microcapsules, so that its capsule breaks and releases its restraint from distilled water. Around 20 microspheres can be arranged inside the deformable chamber, for multi-activation during the use of the cigarette device.
[0051] As can be seen in Fig. 1, the claw 21, which represents the effective outlet of the reservoir 5, is positioned some considerable distance from the outlet end 8. This distance is preferably greater than 10 mm. This means that the composition must flow for a reasonable distance through the device, before being inhaled by the smoker. Thus, it can be heated by the housing surrounding the composition passage 11 and the outlet passage 13. It is diluted and heated by the air in the suction passage 9 and is also heated by the heat generated in the deformable member 31, if it is designed as the element exotherm described above. The smoker, therefore, inhales the composition which is heated to a degree ideally replicating the temperature of the smoke of a real cigarette, but at least heated to a degree in order not to cause discomfort.
[0052] Label 4 is an overcoat that substantially surrounds the entire curved surface of the simulated cigarette. As shown in Fig. 2, it is divided into two sections, namely, 40 and 41, which are colored and patterned to resemble a conventional cigarette with a filter tip. In combination with the deformable member 31, the cigarette end of the cigarette both looks and feels like a conventional cigarette filter. The label has at least one laser-punched hole, so as not to obstruct the entry 24.
[0053] The coatings applied to label 4 demonstrate hydrophobic properties, but also create a lipophobic and oleophobic surface to repel water, dirt on surfaces and any formulation that may be applied or accidentally emitted during the refill process.
This ensures that the cigarette paper does not tear or stain, as the formulation may contain propylene glycol, PEG or aromatic oils, which will result in rapid discoloration of the paper and reduce its structural integrity. As such coatings, phosphonate based application and applied in a monolayer can be used. This can be provided, for example, by Aculon Inc. This will also provide an additional quality of easy cleaning, so that dirt does not accumulate in the nozzle. Since the device is intended to be disposable, a coating can be applied only to the nozzle and the distal end where the refill valve is located, to reduce the likelihood of dirt ingress and tearing of paper. This also provides increased consumer response, so that users can clean the nozzle tip easily without fear of tearing the paper or fabric, for example, if lipstick is accidentally applied.
[0054] Additionally, fluoropolymers can be used, applied directly to the paper or fabric coating as a powder or spray and provide the necessary oil-repellent / water-repellent properties. These may include PTFE (polytetrafluoroethylene), PFA (perfluoroalkoxy polymer resin), FEP (fluorinated ethylene-propylene), and polyethylene-tetra-fluoroethylene ETFE, but not limited to these types of fluoropolymers. Care is taken when choosing a coating that demonstrates adequate biomaterial compatibility, especially if in frequent contact with the skin. [0055] The wrap can be paper-like material, such as a tightly woven cotton, or other fabric and a coating of particles of silica or titania can be used to provide hydrophobic properties in devices where the oleophobic property is not required due to a different composition of the formulation.
[0056] Preferably, a material is used containing a hydrophobic, lipophobic and oleophobic property, but it also has the fire retardant capacity. This is to protect the device in case of being exposed to fire or naked flame unduly. Such coatings may include / Aluminum Trihydride (ATH), Antimony Trioxide (Sb203) and Zinc Borate. Zinc oxides can also be used in a pharmaceutical grade specification, for use in this regard.
[0057] A chemical specialty, MP Protect, available at ISC
Ltd., can also be applied, which incorporates a fire retardant system for substrates rich in cellulose, such as wood, paper, cotton, and certain textile applications. This will allow the ability to withstand flames, according to the burning test of DIN 53438, but it also has the property of granting an antibacterial quality, which can destroy microorganisms, such as influenza, salmonella and Legionella. This can be an important attribute to devices if shared routinely in social situations. [0058] An antibacterial coating on the nozzle can be particularly advantageous as part of a coating or in addition to several coatings, but locally applied to the nozzle. Such coatings may include a thin layer of silver, ionizable silver embedded in the fabric, alloy or silver oxide that will help reduce the spread of bacteria and has been approved for use in breathing devices, such as endotracheal breathing tubes by the FDA. This will provide an improved hygienic aspect to the device if used multiple times before it is eventually discarded.
