Description

Volatilization Device The present invention relates to a volatili2ation device. A volatili2ation device uses a heat source to heat an aerosol generating substance; the resultant volatili2ed aerosol is then delivered to a user. The aerosol generating substance is not combusted.
WO 2008/015441 teaches heating tobacco in order to deliver a volatili2ed material to a consumer in the form of a simulated cigarette. A heat sink is heated by an external heat source, and the heat transferred through a heat pipe to a volatili2ation component containing tobacco. The heat sink is permanently exposed, and after being heated, the hot heat sink may pose a danger to the consumer.
The present invention provides, in a first aspect, a device for delivering volatili2ed material, comprising: a heat sink configured to receive heat from an external heat source, a socket configured to receive a volatili2ation component having a source of volatili2able material, wherein the socket is configured such that the source of volatili2able material is in detachable heat transfer communication with the heat sink; a cover movable between a first position covering the heat sink, and a second position in which the heat sink is uncovered.
The present invention provides, in a second aspect, a kit of parts comprising: a device for delivering volatili2ed material, comprising: a heat sink configured to receive heat from an external heat source, a socket configured to receive a volatili2ation component having a source of volatili2able material, wherein the socket is configured such that the source of volatili2able material is in detachable heat transfer communication with the heat sink; a cover movable between a first position covering the heat sink, and a second position in which the heat sink is uncovered and one or more volatili2ation components configured to detachably connect to the device.
The present invention provides, in a third aspect, a method of delivering volatili2ed material, comprising: providing a device having a heat sink, a socket and a moveable cover; inserting a volatili2ation component having a source of volatili2able material into the socket such that the volatili2ation component is in heat transfer communication with the heat sink; heating the heat sink with an external heat source, moving the cover from a second position in which the cover is uncovered to a first position covering the heat sink.
Thus, the device has a heated part configured to receive heat from an external heat source, and configured to cover the heated part of the device.
The present invention will now be described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a longitudinal cross-sectional view of the device according to the present invention, in a first state; Figure 2 is a perspective view of the device according to the present invention, in a second state; Figure 3 is a further perspective view of the device according to the present invention, in a second state; Figure 4 is a perspective view of the device according to the present invention, in the first state; and Figure 5 is a further perspective view of the device according to the present invention, in the first state.
Figure 1 shows a device I for delivering volatili2ed material. The device I is in the form of a simulated cigarette, and is a reusable device for delivering heat to a replaceable insert. A volatili2ation component 8, which is usable only once and is intended to be disposed of after use, can be releasably connected to the device 1.
The volatili2ation component 8 contains a source of volati2able material, which is so preferably contained in tobacco. Alternatively, the volatili2ation component 8 may contain a volati2able active agent as a source of volatizable material in addition to, or instead of, tobacco. The volatili2ation component 8 may optionally include a volati2able flavouring. Heat from the device I vaporises volati2able material in the component 8, and the volati2ed (vaporised) material may be inhaled as an aerosol.
The source of volati2able material is not burned.
The device I has a heat sink 2 which can receive heat from an external heat source, for example, a cigar lighter. The heat sink 2 is located at an end of the device 1, which will be termed the forward end 26. The heat sink 2 is connected to a heat transfer device, in the form of a heat pipe 4. The heat pipe 4 extends longitudinally along the device I and has a distal end 6. The end 6 is shaped to penetrate into the volatili2ation component 8, which contains the volati2able material. In particular, the end 6 may taper to a point. The volatili2ation component 8 is insertable into an end of the device I opposite to the heat sink 2, which will be termed the rearward end 28.
The heat sink 2 collects and retains heat that is supplied from an outside source.
Heat sink 2 is preferably a metal or ceramic material, such as a honeycomb ceramic, aluminium, or may utilise an encapsulated or closed cell structure containing a phase change material. A suitable phase change material is a eutectic of tin (91 wt%) and 2inc (9 wt%). Preferably, the heat sink 2 is between 15mm to 30mm in length and may have a diameter of around 16.5mm. The heat sink 2 is of a material which can be heated to an operating temperature between around 250 °C to 400 °C.
The heat pipe 4 is preferably a hollow metal tube, for example a titanium, aluminium or copper tube sealed at both ends and filled with a heat transfer material. The heat pipe 4 is arranged to transfer heat from the heat sink 2 to the volatili2ation component 8. Preferably, the heat transfer material comprises a capillary wicking material that is saturated with liquid such as, for example, water.
The heat pipe 4 is preferably around 2mm to 6mm in diameter and around Scm to 9cm in length.
The functioning and further details of the heat sink 2, heat pipe 4 and volatili2ation component 8 may be found in WO 2008/015441, which is incorporated herein by reference.
An inner housing 12 extends longitudinally along the device 1, and surrounds the heat pipe 4. The inner housing 12 is substantially in the form of a cylindrical tube.
At a forward end, the inner housing 12 is attached to the heat sink 2. The inner housing 12 has substantially the same outer diameter as the heat sink 2. At a rearward end, the inner housing 12 forms a socket 14 for receiving the volatili2ation component 8.
The inner housing 12 is preferably made of an insulating material having a low thermal conductivity. A suitable material is one of polyetherimide, polyetheretherketone (PEEK) or another polymer based material.
A plurality of perforations 52 are formed in the inner housing 12, which act as air holes to allow airflow into the inner housing 12.
A moveable cover 20 surrounds the inner housing 12. The cover 20 is substantially in the form of a cylindrical tube, extending longitudinally and forming an exterior of the device 1. The moveable cover 20 is slidable around the inner housing 12 in an axial direction. The moveable cover 20 is approximately the same length as the combined length of the heat sink 2 and the inner housing 12.
The cover 20 is moveable between a first position and a second position. Figure 1 shows the cover 20 in the first position.
In the first position, the cover 20 surrounds the heat sink 2. The cover 20 extends around the periphery of the heat sink 2, The cover 20 therefore inhibits external contact with the heat sink 2, preventing the potentially hot heat sink 2 from contacting the external environment. The first position is at a forward position relative to the inner housing 12.
so In the second position, the cover 20 does not surround a substantial part of the heat sink 2, and in particular, does not extend around the periphery of a substantial part of the heat sink 2. In the second position, the heat sink 20 is uncovered. The cover therefore allows the heat sink 2 to be heated by an external heat source, for example, a cigar lighter. The second position of the cover 20 is at a rearward position relative to the inner housing 12.
The cover 20 is preferably made of two materials having different thermal properties. A first part 22 of the cover adjacent a forward end 26 is preferably made of a material suited to withstand the temperature of the hot heat sink 2, which may be in the range 250 °C to 400 °C. The first part 22 of the cover 20 overlies the heat sink in the first position, and so is in close proximity to the heat sink 2. The first part 22 of the cover 20 is preferably made of a ceramic material.
A second part 24 of the cover 20 adjacent a rearward end 28 is preferably made of a material suited to withstand lower temperatures than the first part. The heat pipe 4 is at a lower temperature than the heat sink 2, and the inner housing 12 provides insulation from the heat pipe 4. The second part 24 of the cover 20, forming the majority of the length of the cover, is preferably made of one polyetherimide, polyetheretherketone (PEEK) or another polymer based material. In particular, the second part 24 of the cover 20 may be formed of the same material as the inner housing 12.
The movable cover 20 protects the user from the heat sink 2 when device I is in use, and the heat sink 2 has been heated. The moveable cover 20 and inner housing 12 provides thermal insulation for the hot parts of the device 1, protecting the user and retaining heat in the heat sink 2 and heat pipe 4.
The inner housing 12 and cover 20 may be connected by a mechanism including runners and rails which provides for relative movement. Alternatively, the device may comprise any mechanism allowing relative movement between the inner housing 12 and cover 20, in particular axial sliding movement.
Jo A biasing mechanism is configured to urge the movable cover into one of the first or second positions. Preferably, the biasing mechanism is arranged to bias the cover from the second position into the first position. The biasing mechanism is preferably a coil spring 30 extending axially between the inner housing 12 and the movable cover 20. The spring 30 is compressed between a flange 42 at the rearward end of the inner housing 12 and a shoulder 44 on an interior surface of the cover 20. The spring 30 acts to urge the cover 20 forwardly, over the heat sink 2. The cover 20 can be manually retracted from the first position to the second position.
The cover 20 may be moved from the first position to the second position by pushing the volatili2ation component 8 against the bias of the biasing mechanism, which compresses spring 30.
The inner housing 12 and movable cover 20 are co-axial tubes, which define between them an air gap 32. The air gap 32 extends around the circumference of the inner housing 12, and may extend over only part or substantially the whole length of the device 1, and the air gap may extend continuously or be formed of discrete sections. The air gap 32 defines a pre-determined volume of air which acts as an insulating layer. The air gap 32 may optionally be considered to include the air in the region in which spring 30 is located. The air gap 32 may also be considered as the area adjacent the forward end, between the heat sink 2 and the cover 20, and at a separate area adjacent the rearward end. The air gap 32 improves thermal insulation between the hot components of the device 1, the heat pipe 4 and heat sink 2, and the exterior surface of the device 1.
The device I is configured to releasably hold the cover 20 in the selected first or second position. The cover 20 is held in the first position by the biasing mechanism urging the shoulder 44 against a shoulder 46 connected to the inner housing 12.
The cover 20 is releasably held in the second position by a mechanism which will be described below, with reference to Figures 2 to 5.
In the first position, the cover 20 extends over the entire length of the device 1. The cover 20 forms the entire peripheral exterior surface of the device 1. In the second position, the heat sink 2 is exposed, and the cover 20 forms the remainder of the peripheral exterior surface of the device 1.
The device I is configured to receive a replaceable volatili2ation component 8 containing a source of volatili2able material. The present invention may comprise a kit including the device I and one or more volatili2ation components 8.
The volatili2ation component 8 preferably has a stepped outer diameter, defining a smaller diameter portion 48 and a larger diameter portion 50. The smaller diameter portion 48 is dimensioned to closely fit in the socket 14. The smaller diameter portion 48 may be provided with a bore 10 into which an end 6 of heat pipe 4 can enter, allowing transfer of heat from the heat pipe 4 to the source of volati2able material. The bore 10 has an interior diameter substantially matching an exterior diameter of the heat pipe 4.
The larger diameter portion 50 abuts against the rearward end of the socket 14, and prevents the volatili2ation component 8 from entering too far into the device 1. The larger diameter portion 50 is dimensioned to have a smaller diameter than an inner diameter of the cover 20, such that the cover 20 can surround the volatili2ation component 8 in the second position.
The volatili2ation component 8 may further comprise a filter section (not shown) axially aligned with a volatili2ation section containing the source of volatili2able material. The filter section defines a mouthpiece end. The filter section preferably comprises a cross-linked polypropylene web, or a high denier per filament cellulose acetate, or a shaped cellulose acetate tube. The filter section is attached to the volatili2ation section by an outer paper wrap.
In the first position shown in Figure 1, the cover 20 does not extend over the larger diameter portion 50 of the volatili2ation component 8, and the cover 20 does not extend substantially rearwardly of the inner housing 12. The volatili2ation component 8 is accessible to a consumer, who can draw on the volatili2ation component 8 in order to inhale vaporised material.
Figures 2 and 3 show the device I in a second state, in which the cover 20 is in the second position and the heat sink 2 is exposed. The heat sink 2 can be heated by an external heat source, since it is not surrounded by the cover 20. The cover 20 has moved axially relative to the inner housing 12 from the first position. In the second position, the cover 20 extends rearwardly of the inner housing 12 to partially or fully cover the volatili2ation component 8. The cover 20 preferably extends such that the rearward end 28 is substantially aligned with the rearward end of the volatili2ation component 8.
The heat sink 2 is substantially cylindrical, with a series of concentric ribs on curved sides 38. The ribs increase the surface area of the heat sink 2. A forward end 40 of heat sink 2 is preferably planar.
The cover 20 is preferably releasably held in the second position by a retaining mechanism. The retaining mechanism includes a catch, preferably in the form of a button 36. The button 36 is urged radially outwardly by a spring (not shown) into an aperture 37 in the movable cover 20. Figures 2 and 3 show the button 36 extending through the aperture in the cover 20, and flush with the exterior surface of the cover 20. The engagement of the button 36 in the aperture 36 prevents axial movement of the cover 20. In order to move the cover 20 into the first position, the catch is actuated to release the moveable cover 20. The button 36 is depressed such that it no longer engages with the aperture. The cover 20 is provided with only one such aperture 37, so the button 36 restricts movement of the cover 20 only in the second position. The force applied by the biasing mechanism 30 actuates the relative movement between the cover 20 and inner housing 12 until the cover 20 reaches the first position.
The cover 20 is described as held in the second position with a button extending through the cover, and in the first position with abutting shoulders 44, 46.
Alternatively, the device I may be provided with a different mechanism for securing the cover 20 in the first and/or second position. One or more ball bearings may be so used to secure the cover in the first and/or second position, instead of the button 36 and spring. The one or more ball bearings may be held in permanent positions on the inner housing 12, and allowed to roll freely. The external cover 20 has an interior surface in contact with the ball bearings. The external cover 20 may be provided with one or more protrusions or traps' on the interior surface which are engageable with the ball bearings, to prevent movement of the inner housing 12 beyond the first and/or second position. Alternatively, the one or more ball bearings may be urged radially outwardly by a spring, and may engage with an aperture in the cover 20 to secure the cover in the first and/or second position.
An indicator may be located on the device in order to indicate when the heat sink 2 has achieved an operating temperature. The indicator may be a thermo-chromic dye on the cover 20, inner housing 12 or on the heat sink 2. Alternatively, a different type of visual indicator may be located on the device 1. Alternatively, the device I may have a sound generator to generate an audible sound when the heat sink 2 has achieved an operating temperature.
Figure 3 shows the device I from a rearward end. A volatili2ation component 8 is not inserted into the device 1.
Figures 4 and 5 show the device I with the cover 20 in the first position. The cover extends over the heat sink, and in particular, surrounds the curved sides 38 of the heat sink 2. The cover 20 does not cover the forward end 40 of the heat sink 2.
The heat sink 2 is considered as covered in this first position since a substantial part, in particular the curved periphery, of the heat sink is covered. Preferably, the cover 20 extends a short distance forwardly of the forward end 40 of the heat sink 2.
In the first position, the button 36 is not aligned with aperture 37, and so does not extend into aperture 37.
Figure 5 shows the device I from a rearward end. A volatili2ation component 8 is not inserted into the socket 14.
In use, the volatili2ation component 8 is inserted into the socket 14 of the inner housing 12, with the heat pipe end 6 being received in contact with the source of -10 -volatili2able material in the volatili2ation component 8. The cover 20 may be in the first or second position for the volatili2ation component 8 to be inserted.
The cover 20 is then moved to, or maintained in, the second position such that the heat sink 2 is accessible. The cover 20 may be moved to the second position by the user holding the cover 20 and pushing the inner housing 12 or volatili2ation component 8 forwardly. In the second position, the cover 20 is positioned to expose a substantial part of the heat sink 2, such that the heat sink 2 can be heated.
The heat sink 2 is heated from an external heat source, for example, a cigar lighter.
The heat sink 2 is heated to an optimum temperature, which may be indicated by an indicator. When the heat sink 2 reaches a desired temperature, heating is ceased.
The cover 20 is moved to the first position, preferably by releasing a catch which allows the biasing mechanism to actuate the relative movement of the cover 20 and inner housing 12. Preferably, the catch is released by depressing button 36.
The user draws on the rearward end of the volatili2ation component 8. Air passes into the device through air holes 52, and the air is heated by the heat transfer pipe 4. The heated air then passes through the tobacco, active agent and/or flavouring of the volatili2ation component 8, which has also been heated by contact with the heat pipe 4. The hot air volatili2es the tobacco, active agent and/or flavouring, which is then drawn into the mouth of the user.
After the tobacco, active agent and/or flavouring in the volatili2ation component 8 have been exhausted, the volatili2ation component 8 is removed with the cover in the first position. A fresh volatili2ation component 8 may then be inserted into socket 14.
The device I has been described as having an inner housing 12 co-axial with the cover 20. Alternatively, the device I may not have an inner housing. The movable cover 20 may form a single sleeve around the heat sink 2 and heat pipe 4. The cover may be attached by a supporting structure, not being a sleeve, to the heat sink 2 and heat pipe 4.
-11 -The cover 20 has been described as having two parts formed of different materials.
Alternatively, the cover 20 may be formed of a single material. Preferably, the single material is a polymer material.
The volatili2ation component 8 has been described as having a bore for receiving the heat pipe. Alternatively, the volatilization component 8 may not have a bore, and comprise a solid cylinder of volatili2able material. The heat pipe 4 may be configured such that only an end surface of the heat pipe end 6 contacts the volatili2able material. Alternatively, the heat pipe end 6 may be shaped to penetrate into the tobacco or a substrate in the volatili2ation component 8, to improve contact and heat conduction. The heat pipe end 6 may take the form of a screw, a single penetration needle, a cone with flat fins or a plurality of penetration needles.
The volatili2ation component has been described as containing tobacco, which provides the source of volati2able material. Alternatively, the volatilization component 8 may not contain tobacco and the volati2able material is an active agent and/or flavouring stored in the volatilization component 8.
Any of the features described in any of the embodiments or in the described prior art embodiments may also be applied to any other of the embodiments of the present invention.
