Definitions

  • the present invention relates to the field of tobacco, in particular to reconstituted tobacco as well as aerosol-generating articles.
  • the present invention further relates to smoking devices, especially to an electrically heated e-liquid system or an electrically heated aerosol-generating system.
  • Illicit trade of aerosol-generating articles is a problem, as counterfeit articles in particular may be of inferior quality or, may not be suited to a specifically dedicated aerosol generating system.
  • a code or equivalent marking containing information about the article may be arranged onto an outer surface of the article, for it to be detected in use or prior use with a certain device. This allows to check for authenticity of the consumable article and in case of negative check, to provide an appropriate control, such as to power off the heating system with which it is used.
  • WO2017207442A1 discloses a tubular aerosol-generating article, marked with an identifier.
  • the identifier is arranged on the inner surface of the article or can be anywhere.
  • the tubular aerosol generating article comprises a mouthpiece, a proximal end and a distal end configured to receive the heating portion of the main unit.
  • the identity of the tubular aerosol-generating article comprises a sensor system and the detection is done by optical scanner and electric circuitry.
  • the system disclosed in WO2017207442A1 is limited to either a variation of an intensity or change of electrical current or resistive information when a stick has been introduced. For example, the system may detect a single resistance value that may be compared by values stored into a lookup table. Therefore, the system is limited to low density codes and would be easy to reproduce.
  • WO2019129378A1 discloses an inhaler for heated cigarette rods
  • the invention is achieved by a method to identify coded information arranged on an aerosol-generating consumable article.
  • the article defines an insertion direction Z and comprises at least one indicium containing coded information about the article arranged on or inside said article; the aerosol generating device comprising a heating cavity arranged for insertion of the article along the insertion direction and comprising an indicium detection system .
  • an indicium or indicium layer may be made of an array of electrically conductive layers arranged in the length of said insertion direction Z and wherein said indicium detection system comprises at least one electrical detector. Similar detection methods as the ones used in the case of optical detection schemes may be applied, such as the use of conductive conical shaped indicia.
  • said conductive layers are metallic layers. Thin metallic layers such as thin wires may be easily integrated in an article. These layers may be arranged for example as an array of metallic wire parts. Metallic wires or layers may have a rigidifying function. Because of their rigidity metallic wires or layers may be easily introduced into the article for example in glue or bond or as separation layers on an article.
  • the detection may be based on the detection of electrical and/or magnetic properties of the indicium.
  • Electrical detection methods may be based on the detection or measurement of a capacitance, an inductance, or a resistance. Using electrical and/or magnetic detection of a moving indicium is simpler than optical detection because it requires less space.
  • a movement of the aerosol-generating article may be realized after the full insertion of the article in said cavity.
  • the movement may be, for example, any back-and-forward movement of the aerosol-generating article after it has been inserted in the cavity 200.
  • indicia 10 are realized onto or into layers that may have typically one of the functions of: - joining or adhesion;
  • Indicia may also be arranged on parts or inserts or layers that are incorporated into or onto an article for the mere purpose of proving an indicium.
  • an indicium 10 may be formed by at least two straight lines or stripes that are arranged according to an angle relative to a longitudinal axis of an article 10.
  • an indicium 10 may comprise two thin lines or strips that are separated by a small distance or be in contact at the side of the consumable portion of an article, and having a greater separation at the side to the mouthpiece of an article.
  • Such lines or stripes may have a curved shape and/or have a variable width.
  • Said at least two straight lines or stripes may have an angle relative to each other or may even be crossing lines or stripes.
  • an indicium may comprise two thin lines that present a relative angle of less than 10°, preferably less than 5°, which is difficult to detect by the un-aided human eye.
  • Such variant can also be combined with the embodiment of Fig.8, further described, that comprises an additional longitudinal code, possible a bar code extending in the length of said two lines or strips.
  • a layer may overlap, at least partially, another layer that is also used as indicium 10; layers may have any 2D and/or 3D shape , the 2D shape being defined in the plane of the layer.
  • a shape is defined by a polynomial, such as a triangle, a pentagon, an ellipse, or an oblong shape;
  • variable width may be a series of continuous or discontinuous steps arranged over at least a portion of its length.
  • indicia 10 may be formed by a thickened predetermined area of a surface of an article 1 .
  • an indicium 10 may be formed by at least two optical or electrical layers 10, 10’ that have different optical transmission or reflection properties, or different electrical properties.
  • said indicium 10 is made of an array of successive conductive layers arranged in the length of said insertion direction Z and wherein said indicium detection system 100 comprises at least one electrical detector 110.
  • said conductive layers are metallic layers.
  • the layer is a graphite layer or a conductive ink layer.
  • a layer of an article may have a directional conductivity.
  • the conductivity may be different in two orthogonal directions. This may be realized for example by directional doping of the layers.
  • different types of conductive layers may be implemented on or into the same consumable article 1.
  • an electrical detector 100 of the invention is configured to detect at least an electrical resistance between said conductive layers 10 and said electrical detector.
  • said indicium 10 is made of an array of magnetic layers 10 arranged in the length of said insertion direction Z, and wherein said indicium detection system 100 comprises at least one magnetic detector configured to detect a magnetic field generated by said magnetic layers.
  • said indicium 10 is made of at least a first array 10’ and a second array 10” of detectable layers that are both extending along or parallel to said insertion direction Z.
  • the signals S1 , S2 provided by the optical or electrical effect each of said at least a first array 10’ and a second array 10” of detectable layers are detected by at least one detector 110, 110’ and are superposed to provide a superposed signal S3 that provides a unique identification code identifying the aerosol-generating consumable article 1.
  • Said detector 110, 110’ may be an optical or electric or magnetic sensor but may also be a sensor that is configured to measure optical and electrical effects at the same time.
  • a sensor may detect a polarisation state and at the same time be configured as a Faraday effect sensor wherein the polarisation state changes upon an induced current, for example induced in a metallic layer or wire.
  • said indicium detection system 100 comprises at least one electrical detector 130 and at least one optical detector 140.
  • Fig.9 illustrates how a first signal Sz may be provided in relation with the longitudinal distribution of code elements 1001, 1004, 1007, 1010 of the indicium 10.
  • Fig.9 shows exemplary signals Sz1, Sz4, Sz7, Sz10 corresponding to longitudinal-oriented code elements 1001 , 1004, 1007, 1010.
  • the variations of the widths of the steps of the indicium may provide an addition signal Sy, which maxima area aligned with the centre of the steps as illustrated in Fig.9.
  • Sy which maxima area aligned with the centre of the steps as illustrated in Fig.9.
  • the sum of the signals Sx related to the longitudinal code elements and the signals Sy related to the information on the variation of width or presence of steps constitute a code signal S1+S2 that comprises much more information than simpler codes such as the one illustrated in Fig.1.
  • an aerosol-generating device 2 comprising, arranged in an outer body a power supply section (not illustrated) and a cavity 200 defining a cavity axis 204, said body having an opening accessible at the outer body and being configured to receive a consumable article 1 defining an insertion direction Z.
  • the aerosol-generating device 2 further comprises an indicium detection system 100 configured arranged in the device 2 to detect said readable code optically and/or electrically during the insertion movement of said article 1 into said cavity 200 from a proximal end 2a to a distal end 2b thereof.
  • an aerosol-generating article 1 defining an insertion direction Z and comprising at least one indicium 10 containing coded information about the article 1 , said indicium 10 and said coded information being arranged along or parallel to said insertion direction Z for being readable by an indicium detection system 100 of an aerosol-generating device 2 during the movement of insertion of said aerosol-generating article 1 into said aerosol-generating device 2.
