专利说明:

[001] The present invention relates to a pressurized refill can with an outlet valve. It was designed, in particular, for a charger for a simulated cigarette as described in WO 2009/001078. However, it can also be used in other products that require a pressurized gas recharger.
[002] In WO 2209/001078, a simulated cigarette is proposed, the dimensions of which are similar to those of a conventional cigarette. The cigarette has a reservoir for receiving a pressurized gas including a propellant. The reservoir has a breathing activated valve at one end (as described in more detail in WO 2011/015825, in WO 2011/015826) and a recharge valve at the opposite end.
[003] A refill pack has the shape and size of a normal cigarette pack with a refill gas cylinder and has a filling valve that is arranged to couple with the refill valve on the cigarette to periodically refill the cigarette.
[004] As described in WO 2009/001078, the reload valve of the device is a non-return valve that is ordered in a closed position and the can reload valve comprises a hollow nozzle with side holes which is also spring-loaded. When the two are pushed together, the nozzle pushes the check valve away from its rest, thereby initially exhausting the device. Subsequent pushing of the device into the nozzle causes a shoulder on the recharger to engage and engage with an annular assembly at the end of the device to provide a seal. Subsequent movement causes the nozzle of the can filling valve to be compressed against its spring, thereby opening a flow path from the recharger to the cigarette. The nozzle in the can filling valve is provided with a pair of side outlets that are generally perpendicular to the central hole through the nozzle. The valve rest of the device, however, has a flat surface against which the cylindrical refill nozzle is pushed. In addition, the refill nozzle has a considerably smaller diameter and a longer length than the inlet passage of the recharge valve of the device. This would result in a significantly high probability of misalignment during filling due to sliding, thereby providing a filling mechanism prone to damage the refill nozzle.
[005] Also relevant to the invention are the refill valves used for butane gas to refill cigarette lighters and the like. Lighters are filled with butane, the expandability of which is significantly different from that of the propellant based system with which the present invention is of interest. It is also of significantly lower pressure than the pressure required to refill a simulated cigarette based on propellant. With a propellant-based 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 is depleted, the pressure in the reservoir drops. This means that they can be filled from a recharger without necessarily having to exhaust the chamber. The recharging process for a butane system is typically assisted by the use of a relatively large cylinder that is attached in an inverted configuration above the lighter to provide gravity assistance to the recharger.
[006] The connectivity between the lighter inlet valves and an outlet valve of a recharge cylinder operate in a way that allows them to perform the function of filling a reservoir without exhausting it. If the lighter reservoir is filled with air due to an incorrect filling technique, the reservoir would need to be exhausted before filling. In this case, the exhaust procedure is the actuation of 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 built into the valve of a lighter. There is no description of the nature of the refill valve.
[007] Also of some superficial similarity to the present invention are some pressurized metered dose inhaler (PMDI) valves, such as that described in WO2008 / 071901.
[008] These have a nozzle in the form of a blind hole that is closed at one inner end and opened at the opposite end with axially spaced side holes extending through the nozzle wall in the axial hole. The dispenser body is provided with annular seals that surround the nozzle so that, as the nozzle is compressed in the dispenser, the inner side hole passes through the inner seal, thereby placing the nozzle in communication with the formulation in the can and assisting in providing formulation to the measuring chamber. In additional compression of the hole in the dispenser, the inner side hole passes beyond the inner seal and a hole divider comes in line with the inner seal resulting in the flow of formulation from the dispenser into the measurement chamber through the inner hole. At the same time, the outer side hole crosses the outer seal placing the outer hole in communication with the formulation in the measuring chamber. This results in the flow of a measured amount of formulation out of the chamber through the hole. In its uncompressed configuration, the nozzle is ordered in an external position by a spring in which the external side hole is on the outside of the seal.
[009] Such valves are recharge valves. Also, they are not suitable for use in refilling a simulated cigarette as the measuring chamber is much smaller than the cigarette.
[0010] Recharging, therefore, requires that the cigarette be pressed against the valve several times, which would not work in practice, given the need to exhaust the cigarette before filling.
[0011] None of these documents is capable of overcoming the problems of WO 2008/001078 and there is, therefore, nothing in the technique that represents the robust and reliable valve for recharging a simulated cigarette at relatively high pressures that it requires.
[0012] In accordance with a present aspect of the present invention, a pressurized refill can containing a reservoir of composition including a propellant is provided, and an uncalibrated filling outlet valve comprising a stem displaceable from a first position to the which is requested by a first resilient member when no external force is applied to a dispensing position against action by the first resilient member, the stem comprising a blind hole opened at one outlet end and closed at the opposite end and a side hole in the side wall of the stem leading to the blind hole, the refill outlet valve additionally comprising an annular seal that surrounds the stem by which, in the first position, the side hole is not in communication with the inside of the can, and in the position of dispensing, the side hole is arranged to move into the can via the side hole and along the blind hole to the end of the can. and exit.
[0013] A refill valve with a side hole that moves against the resilient member in selective communication with the can through the seal provides a simple and robust mechanism to achieve an uncalibrated refill outlet.
[0014] Preferably, the stem is slidable through the annular seal.
[0015] Preferably, the first resilient member exerts a force on the rod of at least 5N, and preferably at least 10N when it is in the uncompressed state. This relatively high spring force is required if it is necessary to first overcome the spring force in the device to be recharged to provide a flow path.
[0016] Preferably, the radially outer edge of the stem at the outlet end is rounded. This rounded edge provides improved sealing with a device to be refilled in the event of a slight misalignment between the stem and the device.
[0017] An additional potential problem faced by a refillable device that is designed to contain an inhalable composition is the potential for the reservoir to be filled with an unauthorized substance. For example, if the device can be recharged from a butane charger, this could be dangerous for the user.
[0018] Preferably, therefore, the stem has a maximum outer diameter greater than 3 mm, and in which, at the stem's outlet end, at least part of the stem wall extends inwardly from the outside diameter by at least 50% of the radius.
[0019] This can be expressed in slightly different terms as the stem having a maximum outer diameter greater than 3 mm and, where, within a defined circle at the outlet end having a diameter of 1.5 mm, a characteristic is present .
[0020] In general, for butane gas rechargers and the like, the rod has a relatively small outside diameter and a relatively thin wall to increase the size of the bore and thus the flow for a given size of the rod.
[0021] Providing a significantly larger outside diameter that also extends inward for a significant extent over 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 stem has a focused feature, such as a spoke or cruciform extending across the hole, or a pin that is supported on the stem and occupies a central portion of the stem at its outlet end. For the purpose of the invention, the pin, in this case, is considered to be an extension of the wall.
[0022] In such an arrangement, the device can be dimensioned in such a way that it will only work with a rod that fulfills these requirements. A rod such as a conventional butane rod that has an outside diameter that is very small will not be able to seal against the rest so that significant amounts of the composition will leak around the rod during the reloading process making it useless as a recharge device in practice. Second, any recharger with a larger outside diameter, but which has a conventional thin wall will be able to engage with the rest on the device, but will not be able to press against the filling valve element as there is nothing in the center of such a stem that is in a position to press against the filling valve element. Having a thicker wall, the stem according to the fourth and fifth aspects of the invention is able to press against the valve filling element, so that it correctly operates the device.
[0023] As far as we know, there are currently no refill cans that have a rod that meets the requirements above. There is, therefore, no possibility that the device could be refilled with hazardous substance from any known refill cans.
[0024] The composition preferably comprises a solvent which can be a monohydric alcohol and can additionally comprise a glycol and / or a glycol ether. In this case, the ratio of monohydric alcohol: glycol ether by weight is 6: 1 to 1: 1. Preferably, the composition comprises from 0.1 to 2% by weight of propylene glycol, based on the total weight of the composition. Preferably, the composition comprises from 0.5 to 1.5% by weight of ethanol, based on the total weight of the composition.
[0025] The propellant is preferably a hydrofluorocarbon.
[0026] Preferably, the composition further comprises from 0.001% by weight to 0.45% by weight and more preferably 0.026% by weight to 0.084 by weight of nicotine or a pharmaceutically acceptable derivative or salt thereof, based on the total weight of the product. composition.
[0027] Additional details and advantages of the composition are provided in our previously filed application WO 2014/033437.
[0028] According to a third aspect of the present invention, a combination of a pressurized refill can according to the previous aspects of the present invention is provided in combination with a device to be refilled, the device comprising a reservoir with a pressure valve. filling and an outlet valve, the filling valve comprising a rest and being requested by a second resilient member having a spring force that is less than the spring force of the first resilient member in a position in which it closes the filling valve, a valve element protruding from the rest to the point that, when the stem is inserted into the rest, it displaces the filling valve element to open an exhaust flow path around the valve element and around the outside of the stem, the stem being arranged so that the additional pressure that drives the device and the can together causes the stem to land on the rest and the valve refill outlet opens, thereby creating a flow path from the can into the device’s reservoir.
[0029] This combination provides a simple reload operation as the user is taken into account. They simply need to press the device against the stem in the refill can with a smooth action. The device will then automatically exhaust as the filling valve element is moved, over which the increasing pressure applied by the user will open the outlet valve of the refill and refill the container. The user should hear and possibly see a spray of formulation being exhausted. This then stops when the refill outlet valve is opened. In addition, the user should feel a slight thrust when the device's reservoir is full.
[0030] The device is preferably a simulated cigarette.
[0031] Preferably, the outlet valve of the device is a valve activated by breathing and / or the composition contains nicotine.
[0032] A portion of the rest facing the stem preferably has a spherical surface generally in part that is complementary to a rounded outer flap of the stem. This means that even if the stem is slightly misaligned with respect to the valve seat, the rounded surface of the stem and the rounded edge of the stem will still make reliable contact thereby reducing the potential for any leakage between the stem and the rest during the process of reloading.
[0033] To additionally facilitate the alignment of the stem with respect to the rest, both the stem and the rest have parallel side portions that are complementary to each other. These parallel side portions serve to guide the stem at rest. Preferably, however, the length of the overlap of the parallel side portions when completely coupled to each other extends by less than 8 mm and more preferably less than 3 mm.
[0034] According to a fourth aspect of the present invention, a method is provided for using a combination according to a sixth aspect of the present invention to recharge the device, the method comprising the steps of pressing the device against the valve stem exit with a first force to open the filling valve of the device against the action of the second resilient member for the exhaustion of the device reservoir via a path between the stem and the rest; and increasing the force with which the device rest is pressed against the stem to overcome the force of the first resilient member to open a flow path from the refill can in the device reservoir and disengage the device from the stem to close the valve refill outlet valve and the filling valve of the device.

[0045] The simulated smoking device comprises a simulated cigarette 1 which, in addition to its refill valve, is as described in WO 2009/001078. It has a reservoir for an inhalable composition, a breathing operated valve and a recharge valve described below. In addition to the refill valve, the cigarette will not be described further here.
[0046] Additional modifications to the simulated cigarette device are described in our previous orders WO2010 / 073018, WO2011 / 015825, WO2011 / 015826 and WO2011 / 117580.
[0047] A composition of the reservoir is described in WO2005 / 001085. Additional details are provided in WO2014 / 033437.
[0048] The rest of the simulated smoking device is the recharging device. This comprises a main housing portion 2 which is a plastic mold. It is surrounded by a thin cardboard sleeve 3 on which various information is printed such as promotional information. The size of the housing is preferably similar to the size of a cigarette pack and can be adjusted to adapt to sizing formats, for example, to be the pack size of 10 or 20 cigarettes. The housing 2 has a recess 4 in which the refill can 5 of a pressurized recharge gas is contained. Can 5 has an outlet rod 6 at an outer end. With the can 5 in the recess 4, the nozzle 6 rests above the outlet hole 7. The simulated cigarette device 1 is refilled by being pressed against the refill outlet hole 7 as described in detail below. The can can, instead, simply be a stand-alone cylinder which could then have a greater capacity as it is not compressed by the fact that it needs to fit into a housing sized to the size of a cigarette pack.
[0049] In general terms, the housing 2 is divided into two halves with one half having the can of refill gas 5 and the other part containing an articulated drawer 8 with a release mechanism 8 requested by a spring 10. This arrangement forms the subject of WO 2011/095781.
[0050] This description refers to improvements in the design of the refill valve of the refill can 5 as will be described below with reference to Fig. 4 and / or the simulated cigarette filling valve 1 described below with reference to Figs. 6A and 6B. The interaction between both in the reloading operation is illustrated in Figs. 5A to 5D.
[0051] The refill valve 20 of the refill can 5 is an unmeasured valve that 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 cover is an external annular seal 22 and an internal annular seal 23 which, in the design of the PMDI valve, form the ends of a measuring chamber.
[0052] The valve stem 6 is slidable inside the seals 22, 23 against the action of a spring 25 that provides a stress force greater than 5N and preferably greater than 10N in the rest position shown in Fig. 4. The pressure stem valve 6 is provided at its salutary end with an axial bore 24 that extends axially inward from an outlet 26. A side bore 27 extends radially outwardly from axial bore 24 to the outer periphery of stem 6. In a resting position shown in Fig. 4, the side hole 27 is covered by an external annular seal 22. The seal between the outer seal 22 and the outer periphery of the valve stem 26 prevents the flow from leaving the refill can.
[0053] In the measured valve in which the design [and requested, the valve stem is additionally provided with an external periphery that seals with the internal annular seal 23 with a hole through the stem that provides selective communication with the measurement chamber between the annular seals to charge the chamber. In the present case, however, the stem 6 has a non-circular cross section in the vicinity of the inner annular seal 23 so that it does not seal with the inner annular seal and the chamber between the two annular seals 22, 23 is always open to maintain the main reservoir inside the refill can 5. This makes the valve an uncalibrated valve.
[0054] 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.
[0055] When the outlet rod 6 is compressed, once the side hole 27 passes through the outer seal 22, it opens a flow path from the inside of the refill can through the side hole 27 and along the axial hole 24 for outlet 26.
[0056] As shown in Fig. 4, the radially outer edge of the outlet end of the outlet rod 6 has a curved profile 28 for the reasons described below.
[0057] The filling valve 35 in cigarette 1 will be described with reference to Figs. 6A and 6B.
[0058] Cigarette 1 has an inhalation end 30 associated with a breathing activated valve (not shown), such that sucking on the inhalation end 30 opens the breathing activated valve allowing a user to inhale the contents of the reservoir 31. On end opposite the inhalation end 30 is the filling end 32 which is provided with the filling valve 35 as shown in Figs. 6A and 6B.
[0059] The filling valve comprises a cage 36 that supports the remaining valve components within the filling end 32 of the reservoir 31. The cage has a number of large side openings 37 that allow open communication between the inside of the cage 37 and waste from the reservoir 31.
[0060] Contained within the cage is a second spring 38 requesting a valve element 39 for a closed position as shown in Fig. 5A. The valve element 39 has a circular base 40 from the center from which a projection 41 projects 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 that surrounds the lower part of the projection 41. As best seen in Fig. 5A, the projection 41 has a number of axially extending flow channels 44 starting above the annular sealing element 43 and extending to the upper surface of the projection 41.
[0061] The filling valve 35 is completed by an end cap 45 which has a lower annular 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 projection 41 protrudes.
[0062] The central opening 47 opens in a rest generally spherical part 48 which additionally opens in a cut out region comprising a number of projections extending radially inwards 49, the inner faces 50 which have a part cylindrical configuration to provide a guide for the output rod 6 as described below. Each face 50 has a tapered conductor on the surface 51.
[0063] To refill the reservoir 31 of the cigarette 1, the filling 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 filling valve 35 of the reservoir 31 is closed as the spring 38 pushes the valve element 39 to its upper position in which the annular sealing element 43 seals against the lower annular surface 46 in the end cap 45 Similarly, the refill outlet valve 20 is closed as the side hole 27 is sealed by the outer annular seal 22.
[0064] As the cigarette 1 is pressed on the stem 6, initially, the enlarged driving surfaces 51 of the projections 49 in cooperation with the curved profile 28 on the outlet stem 6 assist the user in aligning the cigarette 1 with the stem 6. Subsequently, the cylindrical face of the stem 6 engages with the inner faces 50 of the projections 49 thereby ensuring that the cigarette 1 is in generally axial alignment with the stem 6. Any slight misalignment between the cigarette 1 and the stem 6 is accommodated, to some extent, by the generally spherical nature of the rest 48 on the end cap 45 and the curved profile 28 on the end of the stem 6 as described below.
[0065] As shown in Fig. 5B, as soon as the stem 6 engages with the upper surface of the protrusion 41 of the valve element 39, it begins to move the valve element 39 downwards. This is because the second spring 38 exerts a weaker force than the first spring 25, so that the valve element 39 begins to move before the stem 6 is moved. This moves the annular sealing element 43 away from the lower 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 lower surface. 46 of the end cap 45, along the flow channels 44 and out of the cigarette 1.
[0066] Once the cigarette 1 is engaged to the point where the curved profile 28 lands on the rest 48 as shown in Fig. 5C, the next opening phase begins. In this position, the cigarette can continue to exhaust as the rest 48 does not form a perfect seal with the curved profile 28 at the end of the valve 6. Due to the fact that the valve element 39 cannot be further compressed, application for additional pressure to cigarette 1 it will now cause the rod 6 to be pushed up 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 space between the annular sealing element 43 and the lower annular surface 46 of the end cap 45. During this period, little or no flow passes through the interface between the rest 48 and the end of the stem 6, as, even though, this sup If the surface is not sealed, the aforementioned recharge flow path 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 rest 48 and the curved profile 28 d points of the rod 6 ensures that its leakage is kept to a minimum, even if the cigarette 1 is angularly deflected to a small degree from the geometric axis of the rod 6. Larger angular deviations are generally prevented by the projections 49 engaging with the rod.
[0067] When the reservoir 31 is full of composition, the user will feel a slight backward push as the pressure in the reservoir 31 equalizes with the pressure in the refill can 5, thus avoiding additional flow. They then push the cigarette 1 away from the can 5, which quickly causes the two springs 25, 38 to return to their respective valves to the closed position.
[0068] The arrangement at the outlet rod end 6 will now be described with reference to Figs. 7 and 8.
[0069] The dimensions required at the end of the output rod are best illustrated defined with reference to the prior art. A nozzle of the type used for refilling butane gas has a relatively small outside diameter and a thin wall. The approach used in the present case must have a much larger outside diameter and a relatively thick wall, or at least some other characteristics present towards the central region at the end of the nozzle. The reason for this is apparent, for example, in Fig. 5B. A relatively large outside diameter is required to reliably engage with the resting region 48. The presence of a thick wall or some other feature in the direction of the central region of the end is necessary to hold against the top of the protrusion 41 to compress the valve element 39. If a conventional butane refill is used to try to fill the cigarette, its relatively thin nozzle would not make contact with the rest 48 and would therefore provide a path leakage around the rod. This would make it useless in practice. Also, if a rod with a larger outside diameter, but a conventional wall thickness were used, this would be able to engage the rest 48 properly. However, the open space in the center of the stem would be so large that it would simply fit over the protrusion 41 and would not be able to compress it.
[0070] The current outlet 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 outlet end is ignored. Within the circle of diameter D, a second concentric circle with a diameter of d of 1.5 mm is defined within which there must be something present on the end face of the nozzle. In other words, at the end of the nozzle, if it has a circular inner diameter d with a diameter of 1.5 mm that has no characteristic present, it will not be able to engage with the projection 41.
[0071] The preferred dimensions for the nozzle 6 are an external diameter of 3.15 mm to 3.20 mm, an internal diameter of 1.10 mm to 1.30 mm.
[0072] Fig. 8A shows a nozzle with a relatively thick wall 60. The wall is of sufficient thickness that extends within the inner circle d.
[0073] A similar effect is achieved in Fig. 8B which has a thin-walled tube 61 with an end cap to provide the required dimensions.
[0074] Fig. 8C has a similar thin wall, but has a pin 62 supported at the exit end by rays 62. As is apparent from Fig. 8C, pin 62 is present within the inner circle of must be able to , in use, engage with the projection 41.
[0075] Finally, in Fig. 8D, a crossbar 63 extends diametrically across the end of the nozzle. This may alternatively be a cruciform or other intermittent feature that is capable of engaging with the projection 41.
