专利说明:

[001] The present invention relates to a pressurized refill can with an outlet valve. It was designed in particular to be a refill for a simulated cigarette such as that described in WO 2009/001078. However, it can also be used in other products that require a pressurized gas refill.
[002] In WO 2009/001078, a simulated cigarette is proposed which has dimensions similar to those of a conventional cigarette. The cigarette has a reservoir for receiving a pressurized gas including a propellant. The reservoir has a breath activated valve at one end (as described in more detail in WO 2011/015825, WO 2011/015826) and a refill valve at the opposite end.
[003] A refill assembly having the shape and size of a normal cigarette pack is provided with a refill gas cylinder and has a refill valve that is arranged to mate with the refill valve on the cigarette for refilling periodically the cigarette.
[004] As described in WO 2009/001078, the refill valve of the device is a check valve which is biased to a closed position and the can refill valve comprises a hollow nozzle with lateral openings and which is also spring loaded . When the two are pushed together, the mouthpiece urges the check valve away from its seat thereby initially exhausting the device. A subsequent thrust of the device over the mouthpiece causes a shoulder on the refill to engage and engage with an annular seat on the end of the device to establish a seal. A subsequent movement causes the mouth of the can filling valve to be pressed against its spring thereby opening a flow path from the refill into the cigarette. The nozzle on the can loading valve is provided with a pair of side outlets which are generally perpendicular to the central hole through the nozzle. The valve seat of the device, however, has a flat surface against which the cylindrical refill nozzle is pushed. Additionally, the refill nozzle has a considerably smaller diameter and longer length than the inlet port of the device refill valve. This will result in a significantly high probability of misalignment during loading due to slippage thus providing a loading mechanism susceptible to damage to the refill nozzle.
[005] Also relevant to the invention are refill valves used for refilling cigarette lighters and the like with butane gas. Lighters are loaded with butane, the expandability of which is significantly different from that of the propellant-based system to which the present invention is concerned. It is also of significantly lower pressure than the pressure required to refill a simulated propellant-based cigarette. With a propellant pot system, the propellant (such as hydrofluoroalkane (HFA)) will expand as the liquid leaves the reservoir thereby maintaining a constant high pressure within the reservoir. With a butane-based system, as the butane gas is depleted, the pressure in the reservoir drops. This means that they can be charged from a recharge without necessarily needing to exhaust the chamber. This refilling process for a butane system is typically assisted by the use of a relatively large cylinder that is held in an inverted configuration above the lighter to provide gravity assist for refilling.
[006] The connectivity between the lighter's inlet valves and the outlet valve of a refill cylinder operate in a way that allows it to perform the function of charging a reservoir without depleting it. If the lighter reservoir becomes charged with air due to incorrect charging technique, the reservoir will need to be exhausted before charging. In this case, the exhaust procedure is actuating the refill valve using a device such as a pen or screwdriver to open the valve and allow any trapped air to escape. US 3 277 674 describes a refillable lighter with an exhaust path incorporated in the valve of the lighter. There is no description of the nature of the refill valve.
[007] Also of some superficial similarity to the present invention are certain pressurized metered dose inhaler (PMDI) valves such as those described in WO2008/071901. These have a nozzle in the form of a blind hole that is closed at one end and open at the opposite end with axially spaced side holes extending through the wall of the nozzle into the axial hole. The dispenser body is provided with annular seals surrounding the nozzle such that, as the nozzle is pressed into the dispenser, the inner side hole passes the inner seal thereby placing the nozzle in communication with the formulation in the can and aiding in the feed formulation to the dosing chamber. By further pressing the hole in the dispenser, the inner side hole further passes the inner seal and a hole divider comes into line with the inner seal resulting in blocking the flow of formulation from the dispenser into the dosing chamber through the hole internal. At the same time, the outer side hole crosses the outer seal putting the outer hole in communication with the formulation in the metering chamber. This results in flow of a metered amount of formulation out of the chamber through the hole. In its untensioned configuration, the mouthpiece is urged to an outermost position by a spring where the outer side hole is outside the seal.
[008] Such valves are not refill valves. Also, they are unsuitable for use in refilling a simulated cigarette as the metering chamber is much smaller than the cigarette. Refill will therefore require the cigarette to be pressed against the valve multiple times, which will not work in practice given the need to exhaust the cigarette before charging.
[009] None of these documents are able to overcome the problems of W02008/001078 and therefore there is nothing in the art that represents the robust and reliable valve for refilling a simulated cigarette at the relatively high pressures it requires.
[0010] According to a first aspect of the present invention, there is provided a pressurized refill can containing a reservoir of composition including a propellant and a nicotine or a pharmaceutically acceptable salt or derivative thereof, the reservoir being at a pressure of more than than 400 kPa at 20°C, and a refill outlet valve comprising a rod with an axial bore open at the axial end furthest from the reservoir to provide an outlet that discharges the composition in an axial direction, the rod being displaceable from from a closed position so that it is urged by a first resilient member with an elastic force of more than 10 N when no external force is applied to a dispensing position against the action of the first resilient member to open a flow path from from the reservoir to the outlet.
[0011] The present invention therefore provides a relatively high pressure can and axial outlet at the end of the hole, the rod being displaceable against a relatively high elastic force. Such a device is readily suitable for being pressed firmly against the charging valve of a simulated cigarette. Furthermore, the fact that the refill valve is required to open against a high elastic force means that it is reliably able to open the refill valve on a device to be refilled prior to opening the refill valve on the can. WO2009/001078 is not well suited to dealing with high tensile strength as the design of the nozzle means there is a high probability of misalignment which limits the force that can be applied to open the reservoir. The greater the opening force that is required, the greater the force on the stem and therefore the higher the probability that a misaligned valve element will prevent the loading valve from opening correctly.
The composition preferably comprises a solvent which may be a monohydric alcohol and may further comprise a glycol and/or glycol ether. In this case, the ratio of monohydric alcohol:glycol or glycol ether by weight is from 6:1 to 1:1. Preferably, the composition comprises from 0.1 to 2% w/w propylene glycol, based on the total weight of the composition. Preferably, the composition comprises from 0.5 to 1.5% w/w ethanol based on the total weight of the composition.
[0013] The propellant is preferably a hydrofluorocarbon.
Preferably, the composition further comprises 0.001% w/pa 0.45% w/p and more preferably 0.026% w/pa 0.084% w/w of nicotine or pharmaceutically acceptable salt or derivative thereof, based on the total weight of makeup.
[0015] Further details and advantages of the composition are provided in applicant's earlier application GB 1215273.2.
[0016] The outer diameter of the rod is preferably greater than 3 mm.
[0017] The refill valve can be a metered valve, as long as it has a relatively large metering chamber. However, preferably it is an undosed valve.
[0018] Preferably the stem is closed at the end opposite the outlet to create a blind hole and further comprises a side hole in the side wall of the stem leading to the blind hole, the refill outlet valve further comprising an annular seal surrounding the stem by that, in the first position, the side hole is not in communication with the interior of the can, and in the dispensing position, the side hole is arranged to move within the can with respect to the seal to open a flow path from the interior of the can through the side hole and along the blind hole to the outlet end.
[0019] The refill valve with a side hole that moves against the resilient member in selective communication with the can through a seal provides a simple and robust mechanism to obtain an undosed refill outlet.
[0020] Preferably in the first position, the annular seal covers and seals the side hole.
[0021] If the side hole is to be positioned as it is for a PMDI valve as mentioned above, this will provide an unintended exhaust path via the valve stem which is opened to allow composition to escape during disengagement. By covering the side hole with the seal, there is no such exhaust path as the side hole does not travel out beyond the seal.
[0022] Preferably, the radially outermost edge of the rod at the exit end is rounded. This rounded edge provides an improved seal with a device being refilled even in the event of a slight misalignment between the stem and device.
[0023] Another potential problem faced by a refillable device that is designed to contain an inhalable composition is the potential for the reservoir to be loaded with an unauthorized substance. For example, if the device can be recharged from a butane gas refill, this could be dangerous for the user.
[0024] Therefore, preferably the rod has a maximum outer diameter of more than 3 mm and, wherein, at the exit end of the rod, at least part of the wall of the rod extends inwardly from the outer diameter by hair. minus 50% of the radius.
[0025] This can be expressed in slightly different terms than the rod having a maximum outside diameter of more than 3 mm, and wherein, within a defined circle at the output end having a diameter of 1.5 mm, there is a present resource.
[0026] In general, for butane gas refills and the like, the rod has a relatively small outer diameter and relatively thin wall in order to maximize the hole size and thus flow rate for a given rod size.
[0027] Provide a significantly larger outside diameter that also extends inward to a significant extent for at least part of its circumference. It may have a relatively thick wall. A similar effect can be achieved with an annular end cap that has the required dimensions. Alternatively, the rod has a localized feature, such as a single spoke or cruciform element extending through the hole, or a pin that is supported on the rod and occupies a central portion of the rod at its exit end. For the purposes of this invention, the pin in this case is considered to be an extension of the wall.
[0028] In such an arrangement, the device can be dimensioned in such a way that it only works with a rod that satisfies these requirements. A stem such as a conventional butane stem which has an outside diameter that is too small will be unable to seal against the seat such that significant amounts of the composition will leak around the stem during the refill process rendering it useless as recharging device in practice. Second, any refill with a larger outside diameter but which has a conventional thin wall will be able to engage with the seat in the device, but will not be able to press against the charging valve element as there is nothing in the center of such a rod which is in a position to press against the charging valve element. Having a thicker wall, the stem according to the fourth and fifth aspects of the invention is able to press against the charging valve element so that it correctly operates the device.
[0029] As far as the applicant is aware, there are currently no refill cans that have a rod that meets the above requirements. Therefore, there is no possibility that the device can be refilled with a hazardous substance from any known refill canisters.
[0030] According to a second aspect of the present invention, there is provided a combination of a pressurized refill can according to the previous aspects of the present invention in combination with a device to be refilled, the device comprising a reservoir with a refill valve. loading and an outlet valve, the loading valve comprising a seat for receiving the outlet end of the stem, a valve element protruding into the seat and being urged by a second resilient member having an elastic force which is less than that the elastic force of the first member is resilient to a position where it closes the loading valve, the valve element protruding into the seat to such an extent that when the rod is inserted into the seat, it displaces the loading element. charging valve to open an exhaust flow path around the valve element and around the outside of the stem, the stem being arranged such that The additional pressure pushing the device and can together causes the stem to rest on the seat and the refill outlet valve to open, thereby creating a flow path from the can into the reservoir of the device.
[0031] This combination provides a very simple reload operation as far as a user is concerned. They simply need to press the device against the rod in the refill can with a gentle action. The device will then automatically exhaust when the filling valve element is moved, after which increasing pressure applied by the user will open the refill outlet valve and refill the container. The user should hear and possibly see a formulation exhaust spray. This then stops when the refill outlet valve is opened. Also, the user will feel a slight push back when the device's reservoir is full.
[0032] The device is preferably a sham cigarette. Preferably, the outlet valve of the device is a breath activated valve and/or the composition contains nicotine.
[0033] The portion of the seat facing the rod preferably has a generally partly spherical surface which is complementary with a rounded outermost edge of the rod. This means that even if the stem is slightly misaligned with respect to the valve seat, the rounded seat surface and the rounded edge of the stem will still make reliable contact thereby reducing the potential for any leakage between the stem and the seat during recharge process.
[0034] In order to further facilitate the alignment of the stem with respect to the seat, both the stem and the seat have portions of parallel sides that are complementary to each other. These parallel sided portions serve to guide the stem into the seat. Preferably, however, the length of the superposition of the parallel sided portions when fully coupled together extends for less than 8 mm and more preferably less than 3 mm.
[0035] According to a third aspect of the present invention, there is provided a method for using a combination according to the sixth aspect of the present invention to recharge the device, the method comprising the steps of pressing the device against the valve stem. outlet with a first force to open the loading valve of the device against the action of the second resilient member to exhaust the reservoir of the device via a path between the stem and the seat; and increasing the force with which the device seat is pressed against the rod to overcome the force of the resilient first member to open a flow path from the refill can into the device reservoir and disengage the device from the rod to close the charging outlet valve and the charging valve on the device.

[0045] The simulated smoking device comprises a simulated cigarette 1 which, apart from its refill valve, is as described in WO 2009/001078. This has a reservoir for an inhalable composition, a breath operated valve and a refill valve described below. With the exception of the refill valve, the cigarette will not be described further here. Other modifications to the simulated cigarette device are described in applicant's earlier applications WO 2010/073018, WO 2011/015825, WO 2011/015826 and WO 2011/117580.
[0046] The composition of the reservoir is described in WO 2009/001085. Further details are provided in WO 2014/033437.
[0047] The remainder of the simulated smoking device is the refill device. This comprises a main housing portion 2 which is a molded piece of plastic. This is surrounded by a thin card sleeve 3 on which various information such as promotional information is printed. The housing size is preferably similar to the size of a cigarette pack and can be adjusted to suit particular sized formats, for example to be the pack size of 10 or 20 cigarettes. The housing 2 has a recess 4 in which the charge can 5 of pressurized refill gas is contained. The can 5 has an outlet rod 6 at its lowest end. With the can 5 in the recess 4, the mouthpiece 6 sits above the refill outlet port 7. The simulated cigarette device 1 is refilled by being pressed against the refill outlet port 7 as described in detail below. The can may instead simply be a single cylinder which may then have a larger capacity as it is not constrained by needing to fit into a housing sized like a cigarette pack.
[0048] In general terms, the housing 2 is divided into two halves with one half containing the refill gas can 5 and the other part containing a hinged drawer 8 with a release mechanism 8 prompted by a spring 10. This arrangement constitutes the object of WO 2011/095781.
This invention relates to improvements in the design of the refill can refill valve 5 as will be described below with reference to Fig. 4 and/or the simulated cigarette refill valve 1 described below with reference to Figs. 6A and 6B. The interaction between the two in the recharge operation is illustrated in Figs. 5A-5D.
The refill valve 20 of the refill can 5 is an unmetered valve which is modified from the valve of a pressurized metered dose inhaler. Fig. 4 shows the end cap 21 of the refill can 5 which has an annular configuration and surrounds the valve. Inside the cap is an outer annular seal 22 and an inner annular seal 23 which, in the PMDI valve design, form the ends of a metering chamber.
[0051] The valve stem 6 is slidable within the seals 22, 23 against the action of a spring 25 that provides a pull force of more than 5 N and preferably more than 10 N in the rest position shown in Fig. 4. The valve stem 6 is provided at its outlet end with an axial bore 24 which extends axially inwardly from an outlet 26. A side bore 27 extends radially outwardly from the axial bore 24 to the outer periphery of stem 6. In the rest position shown in Fig. 4, side hole 27 is covered by outer annular seal 22. The seal between outer seal 22 and outer periphery of valve stem 26 prevents flow out of the can of recharge.
[0052] In the metered valve on which this design is based, the valve stem is further provided with an outer periphery that seals with the annular inner seal 23 with a hole through the stem that establishes selective communication with the metering chamber between the seals rings in order to charge the camera. In the present case, however, the rod 6 has a non-circular cross section in the vicinity of the motorcycle annular inner seal 23 such that it does not seal with the annular inner seal and the chamber between the two annular seals 22, 23 is always open for the main reservoir inside the refill can 5. This makes the valve a non-dosed valve.
[0053] The refill can 5 is designed to operate in the inverted configuration as shown in Figs. 1 to 4. It could, however, alternatively operate in the opposite way if a dip tube were provided to communicate between the bottom portion of the can and the refill valve 20.
[0054] When the outlet rod 6 is pressed, as the side hole 27 passes through the outer seal 22, this opens a flow path from the interior of the refill can through the side hole 27 and along the axial hole 24 to exit 26.
[0055] As shown in Fig. 4, the radially outer edge of the output end of the output rod 6 has a curved profile 28 for the reasons described below.
The charging valve 35 on cigarette 1 will be described with reference to Figs. 6A and 6B.
[0057] The cigarette 1 has an inhalation end 30 associated with a breath activated valve (not shown) such that drawing over the inhalation end 30 opens the breath activated valve allowing a user to inhale the contents of the reservoir 31. At the end opposite the inhalation end 30 is the charging end 32 which is provided with the charging valve 35 as shown in Figs. 6A and 6B.
[0058] The loading valve comprises a box 36 that supports the remaining valve components within the loading end 32 of the reservoir 31. The box has a series of large side openings 37 that allow open communication between the interior of the box 37 and the remainder of the reservoir 31.
[0059] Contained within the housing is a second spring 38 which urges a valve element 39 to a closed position as shown in Fig. 5A. The valve element 39 has a circular base 40 from the center of which a bung 41 protrudes upwards. The lower surface of the base 40 is arranged to receive the top of the spring 38, while the upper annular surface 42 receives an annular sealing element 43 which surrounds the lower portion of the bung 41. As best seen in Fig. 5A, the bung 41 it has a series of axially extended flow channels 44 which start above the annular sealing member 43 and extend to the uppermost surface of the bung 41.
[0060] The charging valve 35 is completed by the end cap 45 which has an annular lowermost surface 46 which seals with the upper face of the annular sealing element 43. The end cap has a central opening 47 through which the bung 41 protrudes. The central opening 47 opens outwardly in a generally partly spherical seat 48 which further opens outwardly into a recessed region comprising a series of radially inwardly extending projections 49 whose inner faces 50 have a partly cylindrical configuration to establish a guide path for the output rod 6 as described below. Each face 50 has a tapered guide on surface 51.
[0061] In order to refill the reservoir 31 of the cigarette 1, the charging end 32 of the cigarette 1 is presented to the outlet rod 6 of the refill can 5 as shown in Fig. 5A. At this time, the charging valve 35 of the reservoir 31 is closed when the spring 38 urges the valve member 39 to its uppermost position where the annular sealing member 43 seals against the lowermost annular surface 46 on the cap. 45. Similarly, the refill outlet valve 20 is closed when the side hole 27 is sealed by the outer annular seal 22.
[0062] When the cigarette 1 is pressed onto the rod 6, initially, the widened guide surfaces 51 of the projections 49 in cooperation with the curved profile 28 on the exit rod 6 assist the user in coating the cigarette 1 with the rod 6 Subsequently, the cylindrical face of the rod 6 engages with the inner faces 50 of the projections 49 thereby ensuring that the cigarette 1 is in general axial alignment with the rod 6. Any slight misalignment between the cigarette 1 and the rod 6 is accommodated, even to some extent, by the generally spherical nature of the seat 48 in the end cap 45 and the curved profile 28 over the end of the rod 6 as described below.
[0063] As shown in Fig. 5B, as soon as the rod 6 engages with the uppermost surface of the bung 41 of the valve element 39, it begins to move the valve element 39 downward. This is because the second spring 38 exerts a weaker force than the first spring 25 so that the valve element 39 starts to move before the rod 6 is moved. This distances the annular sealing element 43 from the lowermost annular surface 46 thus opening an exhaust flow path from the reservoir, around the base 40 of the valve element 39, between the annular sealing element 43 and the surface a. lowermost 46 of the end cap 45, along the flow channels 44 and out of the cigarette 1.
[0064] Once the cigarette 1 is engaged to the point where the curved profile 28 rests on the seat 48 as shown in Fig. 5C, the next opening phase begins. In this position, the cigarette may continue to exhaust as the seat 48 does not form a perfect seal with the curved profile 28 at the end of the rod 6. As the valve element 39 cannot be pressed any further, the application of additional pressure to the cigarette 1 will now cause the rod 6 to be urged upwards into the refill can 5 against the action of the first spring 25 until the side hole 27 is moved into the outer annular seal 22. This opens a refill flow path from the refill can 5 along side hole 27 and axial hole 24, through outlet 26, along flow channels 44 and into reservoir 31 via the space between annular sealing element 43 and annular surface a lowermost 46 of the end cap 45. During this period, little or no flow passes through the interface between the seat 48 and the end of the rod 6 because, although, as mentioned above, this surface is not sealed, the flow path of recharge above menc ionated provides a much larger and more direct flow path to the composition from the reservoir so that any leakage around the valve stem is kept to a minimum. In addition, the spherical nature of the seat 48 and the curved profile 28 at the tip of the rod 6 ensure that this leakage is kept to a minimum even if the cigarette 1 is angularly offset by a small degree from the geometric axis of the rod 6. Larger angles are generally impeded by the projections 49 engaging with the rod.
[0065] When the reservoir 31 is full of composition, the user will feel a slight push back when the pressure in the reservoir 31 equalizes with the pressure in the refill can 5 thereby preventing further flow. They then move the cigarette 1 away from the can 5 which quickly causes the two springs 25, 38 to return their respective valves to the closed position.
[0066] The arrangement at the end of the output rod 6 will now be described with reference to Figs. 7 and 8.
[0067] The dimensions required at the end of the output rod are best illustrated as defined with reference to the prior art. A nozzle of the type used for a refill of butane gas, it has a relatively small outside diameter and a thin wall. The approach taken in the present case is to have a much larger outside diameter and relatively thick wall, or at least some other feature present for the central region at the end of the mouthpiece. The reason for this is evident, for example, from Fig. 5B. a relatively large outside diameter is required in order to reliably engage with the seat region 48. The presence of a thick wall or some other feature for the center end region is required in order to abut against the top of the bung 41 to press the valve element 39. Since a conventional butane gas refill is used to attempt to load the cigarette, its relatively thin nozzle will not contact the seat 48 and will therefore establish a leak path around the rod. This will make it useless in practice. Also, if a rod with a larger outside diameter but a conventional wall thickness were to be used, it would be able to engage seat 48 properly. However, the open space in the center of the rod will be so large that it will simply fit over the bung 41 and will not be able to press on it.
[0068] The present output rod has an outer diameter D of at least 3 mm as shown in Fig. 7. For the purpose of calculating this diameter D, the curved profile 28 at the output end is disregarded. Within the circle of diameter D, a second concentric circle with a diameter d of 1.5 mm is defined within which there should be something present on the end face of the nozzle. In other words, at the end of the mouthpiece, if there is an inner circular diameter d with a diameter of 1.5mm that has no feature present, it will not be able to engage with the bung 41.
The preferred dimensions for the nozzle 6 are an outer diameter of 3.15 mm to 3.20 mm, an inner diameter of 1.10 mm to 1.30 mm.
[0070] Fig. 8A shows a mouthpiece with a relatively thick wall 60. The wall is of sufficient thickness so that it extends within the inner circle d.
[0071] A similar effect is obtained in Fig. 8B which has a thin wall tube 61 with an end cap to provide the required dimensions.
[0072] Fig. 8C has a similar thin wall, but has a pin 62 supported at the output end by spokes 61. As is evident from Fig. 8C, pin 62 is present within the inner circle of going to be able , in use, to engage with the bung 41.
[0073] Finally, in Fig. 8D, a transom 63 extends diametrically across the end of the mouthpiece. This could alternatively be a cruciform feature or some other intermittent feature that is capable of engaging with the bung 41.
