The present application is a national phase entry under 35 U.S.C. § 371 of International Application No. PCT/EP2018/097081, filed Dec. 28, 2018, published in English, which claims priority to European Application No. 17211199.9 filed Dec. 29, 2017, the disclosures of which are incorporated herein by reference.
The present invention relates to a smoking device. In particular, the present invention relates to a smoking device for heating a tobacco consumable to release an inhalable vapour, the smoking device providing storage for additional tobacco consumable.
Smoking devices such as electronic cigarettes which generate a vapour from a liquid are relatively well known and are becoming increasingly popular. Another type of smoking device utilises controlled-temperature heating whereby a tobacco consumable is heated to release a vapour but without increasing the heating temperature to a level at which the material burns. Such smoking devices have the advantage of generating an inhalable vapour without requiring burning of the tobacco consumable. In these known smoking devices, only a specified amount of a tobacco consumable is heated at any one time such that the smoking experience can be tailored to suit the user.
Smoking devices are generally utilised by a user at several time intervals throughout a day. The smoking devices must therefore be suitable to provide the user with sufficient tobacco consumable to enable effective operation of the device. In particular, the user does not want to run out of tobacco consumable. Many of the known smoking devices contain limited tobacco consumable and may require a user to separately carry additional tobacco consumable or containers thereof, such as capsules, in order to replenish the smoking device. Such tobacco consumable and containers thereof are generally not reusable, suitable only to be used with the smoking device in a single instance. There therefore exists a need for a smoking device configured to heat, without burning, a tobacco consumable, the smoking device additionally enabling a user to store additional tobacco consumable for replenishing the smoking device.
It is an object of the aspects of the present invention to provide a solution to the above mentioned or other problems.
According to a first aspect of the present invention there is provided a smoking device comprising a heating chamber for heating a tobacco consumable and a storage portion for storing the tobacco consumable, wherein the storage portion is resealable.
The smoking device according to the present invention is advantageously configured to heat, without burning, a tobacco consumable, in addition to enabling a user to store additional tobacco consumable for replenishing the smoking device. The user is thus able to replenish the tobacco consumable used in the device without having to separately carry additional tobacco consumable or containers thereof, such as capsules. The resealable nature of the storage portion enables the storage portion to be reusable and furthermore, enables the quality of the additional tobacco consumable stored with the device to be maintained.
The smoking device may be elongate. The smoking device may comprise a longitudinal direction, having a longitudinal axis along its length. The smoking device may have a first end and a second end. The smoking device may have a mouthpiece for inhalation situated at or toward the second end. The smoking device may have any suitable dimensions. Preferably, the smoking device is configured to fit into the palm of a hand of the user.
The storage portion of the smoking device may be elongate. The storage portion may comprise a longitudinal direction, having a longitudinal axis along its length. The storage portion of the smoking device may comprise a resealable closure situated at or toward an end of the smoking device, preferably the first end of the device. The resealable closure may have an open and a closed position. The resealable closure may be detachable from the storage portion. Alternatively, the resealable closure may be connected to the storage portion. The resealable closure may be rotatably connected to the storage portion such that the resealable closure has an open and a closed position. By the term “rotatably connected” as used herein, is meant that the resealable closure is connected to the storage portion by a pivot point. It will be understood by a skilled person that the resealable closure may rotate about the pivot point between the open and closed positions. For example, the resealable closure may rotate about the pivot point between the open and closed position in the longitudinal direction of the device, such as a hinged lid or may rotate between the open and closed position laterally from the pivot point. The resealable closure may be slidably connected to the storage portion such that the resealable closure has an open and a closed position. By the term “slidably connected” as used herein, is meant that the resealable closure is connected to the storage portion via an engagement portion such that the resealable closure may slide along the engagement portion between the open and closed positions. It will be further appreciated that resealable closures detachable from the storage portion may in fact remain connected to the smoking device via a linking portion such as a cord, line or strip of material to prevent the resealable closures completely detaching from the storage portion of the smoking device. The open position of the resealable closure is intended to refer to the position of the resealable closure when the storage portion and contents thereof are accessible to a user and the closed position of the resealable closure is intended to refer to the position of the resealable closure when the storage portion is sealed. Examples of suitable resealable closures include detachable closures such as stoppers, bungs, caps including screw caps; rotatable closures such as hinged lids and laterally rotating lids or panels and slidable closures such as sliding lids or panels. Preferably, the detachable closure is a hinged lid. The resealable closure may further comprise a seal associated therewith, operable to seal the storage portion when the resealable closure is in the closed position. The seal may be formed from any suitable material. Examples of suitable materials for the seal include resilient materials such as rubber, plastic, metal and combinations thereof. The resealable closure of the storage portion enables a user to access the storage portion of the smoking device to remove or refill tobacco consumable, whilst maintaining the quality of the tobacco consumable stored therein. It will be understood by a skilled person that the tobacco consumable can thus be stored in the storage portion in an airtight manner. By the term “airtight” as used herein is meant that the change in moisture level of the tobacco consumable in the storage portion is less than 20%, such as less than 10% and preferably, less than 5% of the original value after exposure to 180 days with a room temperature of 22° C. and room relative humidity of 60%.
The storage portion of the smoking device may comprise a separator operable to partition the storage portion into at least a first storage portion and a second storage portion, at least one of the first and second storage portions comprising a resealable closure. Both of the at least first and second storage portions may comprise a resealable closure. When the at least first and second storage portions both comprise a resealable closure, the resealable closure of the at least first storage portion may be at or toward a first end of the smoking device and the resealable closure of the second storage portion may be at or toward a second end of the smoking device. The resealable closures of the at least first and second storage portions may each have an open and a closed position as described above in relation to the resealable closure of the storage portion. The resealable closures of the at least first and second storage portions may each further comprise a seal associated therewith as described above in relation to the resealable closure of the storage portion. The at least first and second storage portions provide a user with different storage options for tobacco consumable. For example, a user may store different varieties of tobacco consumable in each of the at least first and second storage portions or use the first or second storage portion to store any used tobacco consumable, whilst storing fresh tobacco consumable in the other storage portion. The storage portion may be partitioned by the separator such that each of the at least first and second storage portions has the same volume as the other and thus, is operable to receive the same capacity of tobacco consumable. Alternatively, the at least first and second storage portions may be partitioned so as to have differing volumes and differing capacity for tobacco consumable. The separator of the storage portion may be formed from any suitable material. The separator of the storage portion may be moveable to alter the volume of the at least first and second storage portions. The separator of the storage portion may comprise a handle accessible from the exterior of the smoking device to enable a user to move the separator. When the storage portion is elongate, the separator is moveable in the longitudinal direction of the storage portion to alter the volume of the at least first and second storage portions.
The separator may be generally perpendicular to the longitudinal direction of the storage portion. The separator being movable enables the user of the smoking device to tailor the volume and thus, storage capacity of the at least first and second storage portions.
The heating chamber of the smoking device may comprise an opening and a closure associated therewith. It will be understood by a person skilled in the art that the opening and closure associated therewith may enable air to flow through the heating chamber, or alternatively, the heating chamber may additionally comprise other openings to enable air to flow through the heating chamber and facilitate the production of vapour and its movement towards the mouthpiece upon inhalation of the user. The closure associated with the opening of the heating chamber may have an open and a closed position. It will be appreciated that the closure associated with the opening of the heating chamber may enable air to flow through the heating chamber when the closure is in the closed position during use of the smoking device. The open position of the closure of the heating chamber is intended to refer to the position of the closure when the heating chamber and contents thereof are accessible to the user and the closed position of the closure of the heating chamber is intended to refer to the position of the closure when the heating chamber and contents thereof are no longer accessible to a user. It will be appreciated that when the closure of the heating chamber is in the open position and the heating chamber and contents thereof are accessible to the user, the storage portion of the smoking device is sealed when the resealable closure of the storage portion is in the closed position. The closure of the heating chamber may be detachable from the smoking device. Alternatively, the closure of the heating chamber may be connected to the smoking device. Examples of suitable closures include detachable closures such as stoppers, bungs, caps including screw caps; rotatable closures such as hinged lids and laterally rotating lids or panels and slidable closures such as sliding lids or panels. Preferably, the detachable closure is a hinged lid. The closure of the heating chamber may be resealable. It will be appreciated that when the closure of the heating chamber is resealable, the closed position of the closure of the heating chamber is intended to refer to the position of the closure when the heating chamber is sealed. When the closure of the heating chamber is resealable, the closure may be as described above in relation to the resealable closure of the storage portion of the smoking device. It will be appreciated that the closure of the heating chamber will be heat-resistant. The opening of the heating chamber and closure associated therewith enable a user to fill the heating chamber with tobacco consumable and prevent the tobacco consumable from falling out of the heating chamber of the smoking device. The opening and closure associated therewith may be positioned at or toward a first end of the device. The opening and closure associated therewith may be positioned at or toward the same end of the device as the resealable closure of the storage portion. When the storage portion is partitioned into at least a first storage portion and a second storage portion, the opening and closure associated therewith may be positioned at or toward the same end of the device as the resealable closure of the first storage portion. The user can thus easily transfer tobacco consumable from the storage portion of the smoking device to the heating chamber.
The storage portion of the smoking device may be detachable from the smoking device. The storage portion and smoking device may thus comprise a connecting mechanism to facilitate the attachment and detachment of the storage portion. Examples of suitable connecting mechanisms include fastenings such as magnets, latches, clasps, and hook-and-eye closures.
The capacity of the storage portion may be smaller than, the same as or greater than that of the heating chamber of the smoking device. Preferably, the capacity of the storage portion is such that the user can use the device throughout the whole day without having to replenish the tobacco consumable in the storage portion. By the term “capacity” as used herein, is meant the maximum amount of tobacco consumable that can fill the volume of the storage portion. Preferably, the capacity of the storage portion is the same or greater than that of the heating chamber of the smoking device, most preferably, greater than the capacity of the heating chamber.
A user may transfer tobacco consumable from the storage portion of the smoking device to the heating chamber via the resealable closure of the storage portion and the opening of the heating chamber. A user can thus control the amount of tobacco consumable being introduced into the heating chamber according to personal preference. The smoking device may further provide the user with an indication as to when transfer of tobacco consumable from the storage portion to the heating chamber is required. Examples of such indications include visual indications such as a constant or flashing LED light and physical indications such as vibration or pulsing of the smoking device. Alternatively, the smoking device may comprise a transfer mechanism to transfer, in use, tobacco consumable from the storage portion of the smoking device to the heating chamber. Examples of transfer mechanisms include a mechanical network of moveable components, such as flat panels, that transfer a portion of the tobacco consumable, the portion corresponding to the capacity of the heating chamber, from the storage portion to the heating chamber. The transfer mechanism, such as the mechanical network of moveable components may be activated by the user of the device via a trigger such as a button or switch. It will be appreciated that smoking devices comprising transfer mechanisms may further provide the user with an indication as to when transfer of tobacco consumable from the storage portion to the heating chamber is required. Examples of such indications include visual indications such as a constant or flashing LED light and physical indications such as vibration or pulsing of the smoking device. Alternatively, the transfer mechanism may, in use, transfer the tobacco consumable from the storage portion to the heating chamber upon measurement of a predetermined parameter associated with the smoking device. Examples of such predetermined parameters include a predetermined heating time, a predetermined number of inhalations (puffs) taken by a user and a predetermined time since the previous refill. For example, transfer mechanisms may transfer the tobacco consumable from the storage portion to the heating chamber after 5 to 7 minutes of heating, such as after 5.5 to 6.5 minutes of heating, preferably after 6 minutes of heating, after 8 to 12 inhalations (puffs) taken by the user, such as after 9 to 11 inhalations (puffs) taken by the user, preferably 10 inhalations (puffs) taken by the user, within 0.5 hours to 2 hours of the previous refill, such as within 0.5 hours to 1.5 hours of the previous refill, preferably within 1 hour of the previous refill or within 2 to 4 days of the previous refill, such as within 2.5 to 3.5 days of the previous refill, preferably within 3 days of the previous refill.
Tobacco consumable for use in the smoking device may be provided in any suitable form. Examples of suitable forms of tobacco consumable include those such as capsules, sticks, tobacco tablets, free-tobacco, reconstituted tobacco sheets and tobacco foam.
