Figure 1 (FIG.1) schematically illustrates an example of embodiment of a portable device according to the invention, before the mixing of a shredded tobacco substrate and a flavouring agent, and
Figure 2 (FIG.2) schematically illustrates the portable device of figure 1 after the mixing of the shredded tobacco substrate and flavouring agent.

Detailed description of embodiments

The invention aims, notably, at offering a portable device 1 intended, at least, for producing a flavoured tobacco substrate 2 from the mixing of a shredded tobacco substrate 3 and a flavouring agent contained into a container 4.
As illustrated in figures 1 and 2 a portable device 1, according to the invention, comprises at least a first compartment 5, a second compartment 6, a mixing compartment 7, and an access control means 8.
The first compartment 5 is configured to receive a shredded tobacco substrate 3. This shredded tobacco substrate 3 is manually introduced by a user into the first compartment 5.
The second compartment 6 is configured to receive a flavour container 4 comprising a flavouring agent. This flavour container 4 is replaceable by the user of the portable device 1, and can be preferably chosen between several flavour containers 4 containing respectively flavouring agents having different flavours.
For instance, each flavour container 4 may be a rigid capsule or a pouch (possibly similar to a tea bag), preferably made of biodegradable or compostable material. For instance, a polyhydroxybutyrate (or PHB) material or a styrenic block copolymer (or TPS) material can be used.
Also for instance, the flavouring agent may be a gaz or a liquid.
Amongst the possible flavours there may be for example menthol, fruity and fudge, etc.
Also for instance, the second compartment 6 may comprise an opening (not illustrated) that allows the user to retrieve a flavour container 4 that has been used and to introduce a new flavour container 4. Such an opening may be a door that can be locked/unlocked by the user.
The mixing compartment 7 is coupled (directly or indirectly) to the first 5 and second 6 compartments.
The access control means 8 is configured to control accesses between the first compartment 5, second compartment 6 and mixing compartment 7 to allow release of the shredded tobacco substrate 3 and flavouring agent into the mixing compartment 7 so that they mix together to produce a flavoured tobacco substrate 2.
So, in a first (or close) state of the access control means 8 (illustrated in figure 1) the shredded tobacco substrate 3 and flavouring agent cannot be mixed into the mixing compartment 7, while in a second (or open) state of the access control means 8 (illustrated in figure 2) the shredded tobacco substrate 3 and flavouring agent can be mixed into the mixing compartment 7.
This allows a simple and easy production of a flavoured tobacco substrate 2 ready for use.
For instance, and as illustrated in the non-limiting example of figures 1 and 2, the access control means 8 may comprise at least a shutter (or flap) controlling access of the shredded tobacco substrate 3 to an outlet 9 of the first compartment 5.
This (each) shutter 8 may be manually actuated by the user by means of a dedicated control element (or unit), or else electronically actuated by a control device 10 of the portable device 1 when it receives a user command through a user interface 11.
Also for instance, the portable device 1 may be configured to allow release of the shredded tobacco substrate 3 and flavouring agent into the mixing compartment 7 by gravity. In this case, once the shutter(s) is (are) in the second (or open) state, the user must hold the portable device 1 in an approximately upright position to allow the shredded tobacco substrate 3 and flavouring agent to fall into the mixing compartment 7.
Also for instance, the mixing compartment 7 may be adapted to mix the shredded tobacco substrate 3 and flavouring agent when it is shaken (manually) by a user. In other words, once the shredded tobacco substrate 3 and the flavouring agent haven fallen into the mixing compartment 7, the user has just to shake the portable device 1 during several seconds (typically between 5 s and 10 s) in order to mix them and then to obtain the flavoured tobacco substrate 2 into the mixing compartment 7.
Also for instance, the mixing compartment 7 may be made in stainless steel in order to be easily cleaned by the user by means of a suitable brush.
Also for instance, and as illustrated in the non-limiting example of figures 1 and 2, the mixing compartment 7 may comprise a first opening 11 that allows the user to retrieve the produced flavoured tobacco substrate 2. Such a first opening 11 may be, for instance, a door that is locked during shaking and unlocked by the user when he wants to retrieve the produced flavoured tobacco substrate 2. It is important to note that in this embodiment the portable device 1 is used for producing a flavoured tobacco substrate 2 that the user introduces manually in a paper, after retrieval from the mixing compartment 7, before rolling this paper manually or by means of a dedicated rolling device. In this case, the amount of the flavoured tobacco substrate 2 delivered to the user can correspond substantially to a substrate dose necessary for making a cigarette, according to known techniques "Roll your Own" (or "RYO") and/or "Make your Own" (or "MYO"). In this case, the dimensions of the first compartment 5 can be adapted to receive a predetermined amount of the shredded tobacco substrate 3. In other words, the first compartment 5 can be used as a measuring receptacle allowing the user to obtain the desired dose of flavoured substrate. In some cases, the first compartment 5 can comprise visual indicators allowing the user to vary the amount of the shredded tobacco substrate 3 basing for example on the cigarette dimensions and/or number intended to be obtained.
In the embodiment illustrated non-limitatively in figures 1 and 2, the portable device 1 may also allow the user to inhale components produced by heating of the flavoured tobacco substrate 2 into the mixing compartment 7.
In this embodiment, the mixing compartment 7 comprises a heater 12 configured to heat the flavoured tobacco substrate 2 to generate an aerosol when it is supplied with electrical energy, and an aerosol opening 13 for releasing this generated aerosol. Moreover, the portable device 1 comprises a power source 14 storing electrical energy, and the above mentioned control device 10 for controlling supply of electrical energy to the heater 12.
For instance, this power source 14 may be a rechargeable battery. In this case the portable device 1 may comprise an electrical connector to which a charger cable may be connected during a charging session of the rechargeable battery 14. Such a charger cable may be coupled to an (AC) adapter or to a wall socket. The charger cable and/or the (AC) adapter may belong to the portable device 1.
Also for instance, the heater 12 may comprise a ceramic plate providing a temperature around 300°C under control of the control device 10 during a vaping session.
As illustrated in figures 1 and 2, this control device (or controller) 10 may be fixed onto a printed circuit board (or PCB) 15.
Explicit use of the term "controller" should not be construed to refer exclusively to hardware capable of executing software, and may implicitly include, without limitation, digital signal processor (DSP) hardware, processor, application specific integrated circuit (ASIC), field programmable gate array (FPGA), read only memory (ROM) for storing software, random access memory (RAM), and non volatile storage. Other hardware, conventional and/or custom, may also be included. The functions of the control device (or controller) 10 may be carried out through the operation of program logic, through dedicated logic, through the interaction of program control and dedicated logic, or even manually (by the user). These functions may be provided through the use of dedicated hardware as well as hardware capable of executing software in association with appropriate software.
The user interface 11 is coupled to the control device (or controller) 10 and the power source 14 and allows the user to control at least partly the control device (or controller) 10.
For instance, and as illustrated in the non-limiting example of figures 1 and 2, the user interface 11 may be fixed partly to the printed circuit board 15 to ease and simplify its connections with the control device (or controller) 10. But the user interface 11 may have its own printed circuit board connected to the printed circuit board 15 by wires of flexible circuit(s) in order to be deported anywhere.
As illustrated, the control device (or controller) 10, user interface 11, power source 14 and mixing compartment 7 may be housed in a first body 16 of the portable device 1, which is coupled to the second compartment 6.
For instance, the coupling between the first body 16 and the second compartment 6 can be done by screwing by means of two corresponding threaded portions, or by clipping or else by means of magnets.
In the case where the portable device 1 allows the user to inhale an aerosol, it may also comprise an aerosol pipe 17 communicating with the aerosol opening 13 and comprising an outlet 18 for delivering the generated aerosol to a user. Such an aerosol pipe 17 may be detachable in order to be cleaned. Moreover, this aerosol pipe 17 may be made in stainless steel, for instance. More, and as illustrated in the non-limiting example of figures 1 and 2, the aerosol pipe 17 may be fluidly coupled to a mouthpiece (or mouth end) 19 that is more comfortable for the user than the standard outlet 18 of the aerosol pipe 17. Such a mouthpiece 19 may be detachable, for instance to be cleaned or replaced by a new one.
Also for instance, and as illustrated in the non-limiting example of figures 1 and 2, the first compartment 5 may be located above the second compartment 6, and the second compartment 6 may be located above the mixing compartment 7 and may communicate at least with the mixing compartment 7 through an outlet 20, possibly under control of the access control means 8.
With such an arrangement, the first compartment 5 may communicate with the second compartment 6 under control of the access control means 8, as illustrated in the non-limiting example of figures 1 and 2. In this case and as illustrated, the shutter 8 controls the access to the outlet 9 of the first compartment 5 allowing access to the second compartment 6. But in a variant this shutter 8 could control the access to the outlet 20 of the second compartment 6 allowing access to the mixing compartment 7. In another variant (not illustrated), the first compartment 5 could communicate through a pipe (or conduit) with the mixing compartment 7 under control of the access control means 8, while in parallel the second compartment 6 communicates with the mixing compartment 7 through the outlet 20.
In a first variant of embodiment (not illustrated), the second compartment 6 could be located above the first compartment 5, and the first compartment 5 could be located above the mixing compartment 7 and could communicate with the second compartment 6, possibly under control of the access control means 8, and with the mixing compartment 7, under control of the access control means 8.
In a second variant of embodiment (also not illustrated), the first 5 and second 6 compartments could be located at the same level of the portable device 1, and could communicate separately with the mixing compartment 7, possibly under control of the access control means 8.
Also for instance, and as illustrated in the non-limiting example of figures 1 and 2, the second compartment 6 may comprise a piercing element 21 adapted to pierce the flavour container 4 to define hole(s) allowing to release the flavouring agent.
This piercing element 21 is manually actuated by the user when he decides to mix shredded tobacco substrate 3 with the flavouring agent. As illustrated, the piercing element 21 may be fitted in the second compartment 6 so that it can slide when it is pushed by the user inside the second compartment 6. Preferably, this piercing element 21 is fitted against an elastic restoring force that allows it to return to its initial position (illustrated in figures 1 and 2) when the user does not push anymore on it. This elastic restoring force may be provided by a return coil spring 22.
For instance, the piercing element 21 may be made in stainless steel in order to be easily cleaned by the user when it is detachable.
Also for instance, and as illustrated in the non-limiting example of figures 1 and 2, the first compartment 5 may comprise a reservoir 23 containing a liquid, and a sprayer 24 coupled to this reservoir 23 and arranged to spray liquid on the shredded tobacco substrate 3 to moisten the latter (3) before it is released and mixed. This liquid may be water.
The sprayer 24 comprises a pump protruding outside the first compartment 5 and that may be manually actuated by the user for example through successive pushes. In a variant (not illustrated) the sprayer 24 may be fully housed into the first compartment 5 and electronically actuated by the control device 10 when it receives a user command through the user interface 11 (or a dedicated command button (or touch)).
The liquid capacity of the reservoir 23 can be typically equal to 10 ml, for instance. Moreover, the first compartment 5 may comprise an opening that allows the user to retrieve the reservoir 23 in order to refill it, and possibly to clean it. This opening may also offer an access to the first compartment 5 that allows the user to introduce each new shredded tobacco substrate 3. Such an opening may be a door that is locked during shaking and unlocked by the user when he wants to introduce a new shredded tobacco substrate 3 or to refill the reservoir 23.
For instance, the first compartment 5 may be detachable from the second compartment 6. This may ease introduction of a new shredded tobacco substrate 3 or filling of the reservoir 23. In this case, the coupling between the first 5 and second 6 compartments can be done by screwing by means of two corresponding threaded portions, or by clipping or else by means of magnets, for instance.
Also for instance, the second compartment 6 may comprise an ejector (not illustrated) configured to eject a flavour container 4 that has been used. This ejector may be manually actuated by the user when he pulls on it, or may be electronically actuated by the control device 10 when it receives a user command through the user interface 11 (or a dedicated command button (or touch)).
Also for instance, and as mentioned above, the first compartment 5 and the mixing compartment 7 may have a storage capacity that allows storage of an amount of shredded tobacco substrate 3 corresponding substantially to a cigarette dose.
