Description

Vaporisable Material Plug and Capsule The present invention relates to a plug of vaporisable material and a vaporisable material-containing capsule for use in a vapour generating device. Devices which heat rather than burn vaporisable material, such as tobacco, to create a vapour for inhalation are becoming popular. They generally comprise a heat source powered by gas or electricity and a chamber for receiving a plug of vaporisable material or a disposable capsule containing a vapour-generating product. In use the plug or capsule is inserted into the device and heated by the heat source to generate a vapour for inhalation. An example of such a device can be found in PCT publication WO 2009/079641.
Such devices have become popular because they can provide a user with an experience very similar to smoking the vaporisable material but without the burning of plant material such as tobacco.
However, such devices are not always popular with consumers because they can produce inconsistent levels of vapour and are often unreliable in terms of the length of use of an individual capsule, leaving to an inconsistency of flavour delivery to a user.
The present invention seeks to provide a plug of vaporisable material and capsule for containing such a plug which overcomes at least some of these problems.
According to the present invention there is provided a plug of vaporisable material for a vapour generating device which generates a vapour by heating at least the base of the plug, the plug comprising: vaporisable material shaped such that it defines a cavity within the vaporisable material.
The plug may be provided in a capsule.
With a plug or capsule with contents comprising a plug in the manner defined it is possible to provide accurate and consistent filling of the capsule with product.
Furthermore, by defining the thickness of the material within the plug, by provision of the cavity within the contents, when the plug or a capsule containing such a plug is heated in use it is possible to define quite specifically the speed of release of vapour to a user and the length of time over which vapour is released.
Also, by provision of the cavity it is possible to reduce significantly the draw resistance experienced by the user when drawing on vapour produced by the material.
The cavity may be frusto-conical in shape with the apex of the cavity adjacent to the base of the plug or capsule. This improves even more significantly the consistency of flavour delivery and greatly improves a user's experience when using the heating device. The angle of inclination of the frusto-conical shape with respect to a line perpendicular to the base of the plug or capsule may be in the range of 10 to 15 degrees and may be about 12 degrees.
It will be appreciated that the thickness of the contents between the base of the plug and the cavity can be controlled to optimise vapour generation and draw characteristics and may vary dependent on the overall depth of the plug, the material contents and the volume of material. The thickness may be controlled so that the ratio of overall plug depth to thickness of material between the base and the cavity is in the range of thirteen to one and four to one. In one embodiment the cavity may be formed so that the thickness of the contents between the cavity and the base of the plug or capsule is in the range of 1.5 mm +1-0.5 mm.
The material in the plug may comprise tobacco.
One example of the present invention will now be described with reference to the accompanying drawings in which: Figure 1 is a side cross-sectional schematic view of a heating device comprising a capsule according to the present invention; and Figure 2 is a side cross-sectional view through a plug and capsule in accordance with the invention.
Referring to Figure 1 there is shown a tobacco heating device 1 of the type generally described in PCI publication WO 2009/079641. The device has a mouthpiece 10, body 11, heater 12, heating chamber 13 and a fuel supply 14.
The device also usually has control components to regulate the temperature of the device particularly within the heating chamber to control a container 20 placed within the device in use. Whilst this example device uses a combustible fuel as a heat source, it will be appreciated that the device may have another type of heat source and power supply, such as an electrical heater and battery,
for example.
In use a capsule 20 is inserted into the heating chamber 13, and the heater 12 supplied with fuel from the fuel tank 14 to heat the heating chamber 13, under the control of a user. The contents of the capsule 20 are heated by the heater 12 to create an aerosol vapour based on the contents of the container, that aerosol then being inhaled by the user via the mouth piece 10.
Referring to Figure 2, a plug of vaporisable material 25 according to the invention is shown. In this example the plug is provided in a capsule 20. It is possible to provide the plug in a user-removable wrapper which is taken off prior to insertion of the plug 25 into the heating chamber 13 of the device I or to supply the plug 25 in a dispenser which inserts the plug 25 into the device 1 to avoid handling by a user.
The capsule 20 comprises an outer body 21 with a base 22 and opening 23.
Preferably the capsule body is made of a metal, crystalline or noncrystalline inorganic ceramic or plastic material capable of upholding temperatures of at least 180°C. A preferred material for the capsule according to the invention may be aluminium.
The opening 23 is sealed with a foil 24 to retain the plug of material 25 within the capsule 20 during transport and insertion into the device of Figure 1 and to maintain the freshness of the product prior to use. Foil 24 is pierced by the device I upon insertion so that, when the plug of material 25 is heated in use through the capsule 20, the vapour which is generated can pass out of the capsule 20 and through the mouth piece 10. The material from which the plug 25 is formed is vaporisable under heating and may be a tobacco-based product which can have a number of compositions. Examples of the types of material are described in WO 2009/079641. The nature of the composition will depend upon a desired flavour to be provided to a user, as well as other factors such as intended storage lifetime.
It will be noted that the plug of material 25 within the capsule 20 is shaped and positioned within the capsule 20 such that it defines a central cavity 26 within the capsule 20 even when it is filled. It will be noted that in this example the cavity 26 is generally frusto-conical in shape, with the apex 27 of the cavity being at the end closest the base 22 of the body 21 of the capsule 20 when in position. The cavity is formed by compressing the plug material with an appropriately shaped tool. If the plug is to be supplied in the capsule 20 this may be done either before or after the insertion of the plug 25 into the capsule 20 and before the foil seal 24 is applied. By providing such a cavity it is possible to control with accuracy and consistency the thickness d between the cavity 26 and the base 22 of the capsule 20. It will be appreciated that other cavity shapes, such as a cylinder, can ensure accuracy of content thickness d to ensure consistency of vapour delivery and are in accordance with the invention.
In particular however the provision of a frusto-conical shape has further advantages in that it is possible to control, again with accuracy and consistency, the amount of plug material at any particular distance from the base of the plug.
What the applicant has appreciated is that by controlling the distribution of the contents of the plug of vaporisable material 25 with respect to their distance from the base of the plug it is possible to predetermine the heat profile of the contents with respect to time when the plug 25 is heated in use. This in turn ensures that the delivery of vapour, and hence flavour, to a user can also be predetermined with a significant degree of consistency and accuracy. By determining the thickness d of material at the base of the plug (which is where heat is applied), it is possible to predetermine the amount of vapour released on initial heating to control the amount of flavour released to a user. It has been determined that a thickness d in the range of 1.5mm plus or minus 0.5 mm is particularly beneficial in ensuring speedy vapour generation after the start of heating. That is in the example shown in figure 2, a relative ratio of depth to thickness that lies in the range of approximately thirteen to one to four to one.
By controlling the angle of inclination of the frusto-conical cavity it is also possible to control the release of vapour as the capsule heats up over time from the base upwards thereby controlling the profile of vapour delivery over the total heating lifetime of the plug 25 to accurately predetermine the overall time of delivery of the entire contents of the plug in vapour form. This provides a user with a reliable and consistent experience in using the device. In this respect an angle of inclination for the inclined side of the frusto-conical shape in the range of 10 to 15 degrees from a line perpendicular to the base 22 of the capsule 20 has been found to be beneficial and an angle of 12 degrees from such a line is particularly beneficial.
As will be appreciated providing a cavity of frusto-conical shape it is possible to provide a relatively linear heat profile for the plug material with respect to time, which in turn provides a linear vapour delivery. Other cavity shapes, such as a partial ovoid, for example could be selected to provide a non-linear profile and thereby vary the vapour delivery to alter the user inhalation experience in a controlled manner. It should also be noted that the plug of vaporisable material could be inserted straight into an oven of a device without being first introduced in a capsule. Having the plug introduced in a capsule helps the users to remove a used plug in a hygienic manner and avoids contamination of a clean plug by residues left in the oven by a prior plug.
